Step-by-step explanation:
The distance between each big tick mark is 1, (for example take 2 and 1, 2 minus 1 equals to 1), however, in between each of these big tick marks are four small tick marks. The distance between each small tick mark is the distance between each big tick mark divided by the amount of small tick marks plus 1 (1 divided by 4, which is 1/4).
So in this number line you count by 1/4.

Faber Kozlowski had 6 times as much money as Theriault Luigi. After Faber Kozlowski spent 1/3 of his money and Theriault Luigi spent 4/5 of his money, they had a total of $1155 left.
(a) How much money did Faber Kozlowski and Theriault Luigi have altogether at first?
(b) Theriault Luigi spent 3/4 of his remaining money on a hoodie. What fraction of his original amount of money did he spend on the hoodie?
Answers
Answer:
Step-by-step explanation:
Let's use variables to represent the amount of money each person had at first.
Let x be the amount of money that Theriault Luigi had.
Then, according to the problem, Faber Kozlowski had 6 times as much money as Theriault Luigi, which means Faber Kozlowski had 6x dollars.
After Faber Kozlowski spent 1/3 of his money, he had 2/3 of his money left, which is (2/3)(6x) = 4x dollars.
After Theriault Luigi spent 4/5 of his money, he had 1/5 of his money left, which is (1/5)x dollars.
Together, they had a total of $1155 left, which means:
4x + (1/5)x = 1155
Multiplying both sides by 5 to eliminate the fraction gives:
20x + x = 5775
Combining like terms gives:
21x = 5775
Dividing both sides by 21 gives:
x = 275
Therefore, Theriault Luigi had $275 at first, and Faber Kozlowski had 6 times as much, which is $1650 at first.
So, the answer to (a) is $275 + $1650 = $1925.
For (b), Theriault Luigi spent 3/4 of his remaining money on a hoodie, which means he spent (3/4)(1/5)x = 3/20 of his original amount of money on the hoodie.
Therefore, Theriault Luigi spent 3/20 of his original amount of money on the hoodie.
Answer:
(a) $1925
(b) 15%
Step-by-step explanation:
(a)
Let f = original amount of money Faber had.
Let t = original amount of money Theriault had.
"Faber Kozlowski had 6 times as much money as Theriault Luigi. "
f = 6t
"After Faber Kozlowski spent 1/3 of his money"
He has now: 2/3 f
"and Theriault Luigi spent 4/5 of his money"
He has now: 1/5 t
"they had a total of $1155 left"
2/3 f + 1/5 t = 1155
f = 6t
2/3 f + 1/5 t = 1155
2/3 (6t) + 1/5 t = 1155
4.2t = 115
t = 1155/4.2
t = 275
f = 6t = 6(275) = 1650
f + t = 275 + 1650 = 1925
Part (a) answer: $1925
(b)
Original amount: t = 275
He first spent 4/5 of the original amount, so he had 1/5 left.
275/5 = 55
He spent 3/4 of $55 on the hoodie.
3/4 × $55 = $41.25
$41.25/$275 × 100% = 15%
Part (b) answer: 15%

After: 2, 7, 3, 6, 8, 13, 3, 5
Has there been a decrease in the number of crimes since the inauguration of the program? Use the .01 significance level.

Answers
The p-value method yields P (T > 2.119) = 0.0359. It may be said that, at a 1% level of significance, there has been no decline in crime since the program's inception.
Explain about the Paired T-Test:The observations for the paired t-test are drawn from a single random pair sample. There are the same number of observations in both samples. Each respondent has two observations for the experimental variable recorded.
The alternative is:
[tex]H_{0} =[/tex]: Since the program's launch, there has been no drop in the number of crimes.
The alternate theory is that:

Mathematically,
[tex]H_{0} =[/tex] μo = 0
[tex]H_{a} =[/tex] μd > 0
Given table:
Number of Crimes Before After d = (before - after) d²
A 14 2 14-2 = 12 14² = 144
B 7 7 17 - 7 = 0 0² = 0
C 4 3 4 - 3 = 1 1² = 1
D 5 6 5 - 6 = -1 -1² = 1
E 17 8 17-8 = 9 9² = 81
F 12 13 12 - 13 = -1 -1² = 1
G 8 3 8 - 3= 5 5² = 25
H 9 5 9 -5 = 4 4² = 16
Total 8 29 269
The formula for the t statistic is:
t = ∑d / √[n(∑d²) - (∑d)²] / (n - 1)
t = 29 / √[8*269 - 29²] / (8 - 1)
t = 2.119
As a result, the test statistic's value is 2.119.
8 – 1 Equals 7 degrees of freedom.The p-value method yields P (T > 2.119) = 0.0359.The p-value is inconsequential since it exceeds the specified significance level of 0.01 in this case.
This indicates that at a 1% level of significance, the null hypothesis cannot be ruled out.
As a result, it may be said that, at a 1% level of significance, there has been no crime decline in since the program's inception.

The graph of a quadratic function F has zeros of -8 and four and a maximum at -2, 18 what is the value of “a” in the function equation?
Answers
Answer:
Since the given quadratic function has zeros of -8 and 4, we know that the factors of the quadratic equation are (x + 8) and (x - 4).
The maximum of the function occurs at the midpoint between the zeros, which is (-8 + 4)/2 = -2. So, the x-coordinate of the vertex is -2.
We also know that the y-coordinate of the vertex is 18. So, the vertex of the quadratic function is (-2, 18).
Using the vertex form of the quadratic function, we can write:
F(x) = a(x + 2)^2 + 18
Since the function has zeros of -8 and 4, we can write:
F(x) = a(x + 8)(x - 4)
a(x + 2)^2 + 18 = a(x + 8)(x - 4)
ax^2 + 6ax - 128a - 576 = ax^2 + 16ax - 32a
10ax - 96a - 576 = 0
10a(x - 6) = 0
a = 0 or x = 6.
Since the vertex is a maximum and the coefficient of the x^2 term is positive, we know that a > 0. Therefore, we can conclude that x = 6 and a = 3.
Hence, the value of "a" in the function equation is 3.

To find the missing angle measure, we need to use the fact that the sum of angles in a triangle is 180 degrees. Let's denote the missing angle as x. We know that one angle is 38 degrees and another angle is 12.5 degrees.Therefore, the missing angle measure is 129.5 degrees.
By subtracting these two angles from 180 degrees, we get:
180 - 38 - 12.5 = 129.5
Without additional information, it is not possible to determine the remaining parts of the triangle. We would need the lengths of at least one side or the measures of other angles to solve for the missing parts.
The given information states that AC is equal to AB minus mzB. Without knowing the values of AB and mzB, we cannot determine the exact length of AC. We would need additional information to solve for the length of AC.Therefore, the missing angle measure is 129.5 degrees.

The y-intercept of the function F(x) = 2(x - 7)(x - 3) is 42, which means that the graph of the function intersects the y-axis at the point (0, 42).
What is y-intercept?The y-intercept is the point where a function or a curve intersects the y-axis. It is the value of the dependent variable (y) when the independent variable (x) is equal to zero.
According to question:The y-intercept of a function is the point where the graph of the function intersects the y-axis. To find the y-intercept of the function F(x) = 2(x - 7)(x - 3), we need to substitute 0 for x in the equation:
F(x) = 2(x - 7)(x - 3)
So, we have:
F(0) = 2(0 - 7)(0 - 3)
Simplifying this expression, we get:
F(0) = 2(-7)(-3)
F(0) = 42
Therefore, the y-intercept of the function F(x) = 2(x - 7)(x - 3) is 42, which means that the graph of the function intersects the y-axis at the point (0, 42).

Based on the frequency distribution, using the midpoint of each data class, estimate the mean carrying load of the beams tested. For your intermediate

Answers
Based on the given frequency distribution, the estimated mean carrying load of the beams tested is approximately 904.2 pounds per square foot.
Estimate the mean carrying load of the beams tested.To estimate the mean carrying load of the beams tested, we need to find the weighted average of the midpoints of each data class.
First, we need to find the midpoint of each class interval. We can do this by taking the average of the lower and upper limits of each interval:
Midpoint of 860 to 879 = (860 + 879) / 2 = 869.5
Midpoint of 880 to 899 = (880 + 899) / 2 = 889.5
Midpoint of 900 to 919 = (900 + 919) / 2 = 909.5
Midpoint of 920 to 939 = (920 + 939) / 2 = 929.5
Midpoint of 940 to 959 = (940 + 959) / 2 = 949.5
Next, we can find the weighted average of these midpoints, using the frequencies as weights. We can set up a table to organize our calculations:
Data class Midpoint Frequency Midpoint x Frequency
860-879 869.5 5 4,347.5
880-899 889.5 9 8,005.5
900-919 909.5 12 10,914
920-939 929.5 6 5,577
940-959 949.5 2 1,899
Total 34 30,743.5
To find the weighted average, we divide the sum of the products in the last column by the total frequency:
Weighted average = Sum of (Midpoint x Frequency) / Total frequency
Weighted average = 30,743.5 / 34
Weighted average ≈ 904.2
Therefore, based on the given frequency distribution, the estimated mean carrying load of the beams tested is approximately 904.2 pounds per square foot.

An observation is considered an outlier if it is below:
-11.5
Correct
An observation is considered an outlier if it is above:
32.5
Correct
Answers
That's correct. An observation is considered an outlier if it is more than 1.5 times the interquartile range (IQR) above the third quartile (Q3) or below the first quartile (Q1).
How to further determine the value?The IQR is the difference between Q3 and Q1:
IQR = Q3 - Q1
In this case, the first quartile Q1 is 5 and the third quartile Q3 is 16. So the IQR is:
IQR = Q3 - Q1 = 16 - 5 = 11
An observation is considered an outlier if it is more than 1.5 times the IQR above Q3 or below Q1.
To find the upper outlier bound, we add 1.5 times the IQR to Q3:
Upper outlier bound = Q3 + 1.5(IQR) = 16 + 1.5(11) = 32.5
So any observation above 32.5 is considered an outlier.
To find the lower outlier bound, we subtract 1.5 times the IQR from Q1:
Lower outlier bound = Q1 - 1.5(IQR) = 5 - 1.5(11) = -11.5
So any observation below -11.5 is considered an outlier.

What values of y and z make
Answers
The values of y and z that make the triangles to be congruent are 13 each
Calculating the values of y and zFrom the question, we have the following parameters that can be used in our computation:
The triangles
For the two triangles to be congruent, the following equations must be true
2y = y + 13
y + 5z - 20 = 2y + z + 19
When the above equations are evaluated, we have
y = 13
Next, we have
4z = y + 39
So, we have
4z = 13 + 39
Add and divide by 4
z = 13
Hence, the values of y and z are 13

One leg of a right triangle is 14 centimeters longer than the other leg. The length of the is 26 centimeters. What are the lengths of the legs?
Answers
The length of the shorter leg is 6 centimeters, and the length of the longer leg is x + 14 = 20 centimeters.
Explanation:
Let x be the length of the shorter leg of the right triangle.
According to the problem, the longer leg is 14 centimeters longer than the shorter leg, so its length is x + 14.
We also know that the length of the hypotenuse of the right triangle is 26 centimeters.By the Pythagorean theorem, we have:
x^2 + (x + 14)^2 = 26^2
Simplifying the left side:
x^2 + x^2 + 28x + 196 = 676
Combining like terms:
2x^2 + 28x - 480 = 0
Dividing by 2:
x^2 + 14x - 240 = 0
Factoring:
(x + 20)(x - 6) = 0
Therefore, x = -20 or x = 6.
Since the length of a side cannot be negative, we reject x = -20 and conclude that x = 6.
So the length of the shorter leg is 6 centimeters, and the length of the longer leg is x + 14 = 20 centimeters.
Which type of car had the largest range in monthly sales? Explain how you came up with your answer
Answers
Sample Response: I subtracted the highest and lowest numbers. The range for new cars was 31. The range for old cars was 75. The range for used cars was much bigger.
Answer:
Without access to specific data on monthly car sales, it is impossible to determine which type of car had the largest range in monthly sales. However, one possible method for finding this information would be to gather sales data for various car models across multiple months and compare the ranges of their sales figures. Alternatively, one could use industry reports or market analysis to determine which car types tend to have the largest fluctuations in sales from month to month.

find the average rate of change of f(x)=2x^2-2 from 2 to 4
Answers
Answer:
average rate of change = 12
Step-by-step explanation:
the average rate of change of f(x) in the interval a ≤ x ≤ b is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
here the interval is 2 ≤ x ≤ 4 , then
f(b) = f(4) = 2(4)² - 2 = 2(16) - 2 = 32 - 2 = 30
f(a) = 2(2)² - 2 = 2(4) - 2 = 8 - 2 = 6
then
average rate of change = [tex]\frac{30-6}{4-2}[/tex] = [tex]\frac{24}{2}[/tex] = 12
A STUDY OF INTERIOR DESIGNERS OPIONIONS WITH RESPECT TO THE MOST DESIRABEL PRIMARY COLOR FOR EXECUTIVE OFFICES SHOWED THE FOLLOWING
Answers
The probability that a designer does not prefer red is 0.77. The Option 2 is correct.
What is probability?Probability is a measure of how likely an event is to happen. Probability is represented as a fraction and always lies between 0 and 1.
The total number of opinions is:
= 92 + 86 + 46 + 91 + 37 + 46 + 2
= 400
The number of designers who do not prefer red is the sum of the opinions for all colors except red:
= 86 + 46 + 91 + 37 + 46 + 2
= 308
Therefore, the probability that a designer does not prefer red is:
= 308/400
= 0.77.

A trail mix recipe asks for 4 cups of raisins for every 6 cups of peanuts. There is proportional relationship between the amount of raisins, r (cups), and the amount of peanuts, p (cups), in this recipe. Write the equation for the relationship that has constant of proportionality greater than 1.
Answers
Answer:
r/p = 2
Step-by-step explanation:
The proportional relationship between the amount of raisins and the amount of peanuts can be expressed as:
r/p = k
where k is the constant of proportionality.
To find an equation with a constant of proportionality greater than 1, we simply need to choose a value of k that is greater than 1. For example, if we choose k = 2, the equation becomes:
r/p = 2
To check that this equation is correct, we can use the original ratio of 4 cups of raisins for every 6 cups of peanuts:
4/6 = 2/3
This confirms that the constant of proportionality is indeed 2, and that the equation for the relationship with a constant of proportionality greater than 1 is:
r/p = 2
