Answer:
26
Step-by-step explanation:
The number has to be greater than 15 but not less than 25 so any number that is at least 25 works.
Answer:
It would just be at least 26. Because, it's saying that n has to be greater than 15 and greater than 25. so, that the n < 25 is wrong. So i would put 26 because 15 < (is less than) 26, and 26 <(less than) 25 is wrong which is required to be an answer. So you could do 26 through infinity.

A boat travels 3 miles south and then 9 miles east. How far is the boat from the starting point
Tyra's family is spending the afternoon in Millersville. They plan to see a movie and then explore
the town. The movie will cost the family $36, and parking costs $4 per hour.
How long will the family be able to spend in Millersville if they want to spend less than $60 and
they don't have any other expenses?
Follow the steps to answer this question.
1. Write an inequality that shows that Tyra's family spends less than their limit. Explain how you
wrote the inequality, and define any variables used.
2. Solve your inequality. Show your work. What does your solution mean?
Answer: 36+4h=60
36+4h-36=60-36
4h=24
4h÷4=24÷4
h=6
So, after the move they can spend 6 hours there. (6×4=24, 24+36=60, they will spend $60 if they spend 6 hours there, $56 if they spend 5 hours there and don't want to spend $60).

Write an equation that passes through a pair of points
a. y= x+3
b. y= x-3
c. y= -x+2
d.y= -x-2
Answer:
C. [tex] y = -x + 2 [/tex]
Step-by-step explanation:
First, find the slope, m, of the line that passes through the two given points.
Slope = [tex] \frac{rise}{run} = \frac{-2}{2} = -\frac{1}{1} = -1 [/tex]
Next, determine the y-intercept, b.
The y-intercept is where the line intercepts the y-axis. The line intercepts the y-axis at y = 2. Therefore, b = 2.
Now, to get an equation of the line, substitute m = -1, and b = 2 in [tex] y = mx + b [/tex].
✅The equation would be:
[tex] y = -1x + 2 [/tex]
[tex] y = -x + 2 [/tex]

Answer:-3/9
Step-by-step explanation:
When you adding or subtracting fractions they need to have the same denominator... which in the question they do! :) after you get your denominator the same you add the second numerator from the first one, in this one it’s 3 + (-6). Oh no a negative! But don’t worry when you add a negative it’s just like subtracting a regular number, so you really are just doing 3-6 which is -3 then you just put that over the denominator you had before, and you get -3/9

1 1/8 = g - 4 2/5, what does g equal?
Answer:
Step-by-step explanation:
It might help to use decimals
1 1/8 = 1.125
4 2/5 = 4.4
Add these together
1.125 + 4.4 = 5.525 That's the correct answer, but likely not in the form you wanted.
1 1/8 = 9/8
4 2/5 = 22/5
9/8 + 22/5
multiply through by the Lowest Common Denominator
9*5/40 + 22*8/40 =
45/40 + 176/40
221/40
5.525
5 21/40
You get the fraction by multiplying 40 * 0.525 which is 21
So you can express 0.525 as 21 / 40

Jill wrote the number 66 If her rule is add 9,what is the fourth number in jills pattern
Answer:
102
Explanation: 66+36 (9 times 4 is 36 and u add it to the 66 because u have to add 9 four times.)
self check
66+9= 75 (1st slot)
75+9=84 (2nd slot)
84+9= 93 (3rd slot)
93+9= 102 (4th and final slot, what u were looking for to begin with)
Noise levels at 3 airports were measured in decibels yielding the following data:
108,146,160
Required:
a. Construct the 90% confidence interval for the mean noise level at such locations. Assume the population is approximately normal.
b. Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answer:
a) The 90% confidence interval for the mean noise level at such locations
(112.46 , 163.54)
b) The critical value that should be used in constructing the confidence interval
Z₀.₁₀ = 1.645
Step-by-step explanation:
Step(i) :-
Noise levels at 3 airports were measured in decibels yielding the following data
108 146 160
Mean of given data
[tex]x^{-} = \frac{108+146+160}{3} = 138[/tex]
x : 108 146 160
x-x⁻ : -30 8 22
(x-x⁻ )² : 900 64 484
Variance σ ² = ∑(x-x⁻ )²/ n-1
= [tex]\frac{900+64+484}{3-1}= 724[/tex]
Standard deviation
σ = √724 = 26.90
Step(ii):-
The 90% confidence interval for the mean noise level at such locations
[tex](x^{-} - Z_{0.90} \frac{S.D}{\sqrt{n} } , (x^{-} + Z_{0.90} \frac{S.D}{\sqrt{n} } )[/tex]
The critical value that should be used in constructing the confidence interval
Z₀.₁₀ = 1.645
[tex](138 - 1.645 \frac{26.90}{\sqrt{3} } , (138 + 1.645 \frac{26.90}{\sqrt{3} } )[/tex]
( 138 - 25.54 , 138 + 25.54 )
(112.46 , 163.54)

Step-by-step explanation:
Jessica has a four-sided die, a six-sided die, and a 12-sided die. She rolls the three dice once. Let Z be the number of fours showing. Find E[Z] using the indicator method.
Answer:
The value of E [Z] is 0.50.
Step-by-step explanation:
The expected value is computed using the formula:
[tex]E(X)=\sum x\cdot P(X= x)[/tex]
Denote the three dices as follows:
X₁ = a four-sided die
X₂ = a six-sided die
X₃ = a 12-sided die
Define the indicator variables as follows:
[tex]I_{1}=\left \{ {{1;\ X_{1}=4} \atop {0;\ X_{1}\neq 4}} \right. \\\\I_{2}=\left \{ {{1;\ X_{2}=4} \atop {0;\ X_{2}\neq 4}} \right. \\\\I_{3}=\left \{ {{1;\ X_{3}=4} \atop {0;\ X_{3}\neq 4}} \right.[/tex]
The probability of rolling a 4 in the three dices are as follows:
[tex]P(X_{1}=4)=\frac{1}{4}\\\\P(X_{2}=4)=\frac{1}{6}\\\\P(X_{3}=4)=\frac{1}{12}[/tex]
Compute the value of E [Z] as follows:
[tex]E(Z)=E(I_{1})+E(I_{2})+E(I_{3})[/tex]
[tex]=(1\times\frac{1}{4})+(1\times\frac{1}{6})+(1\times\frac{1}{12})\\\\=\frac{3+2+1}{12}\\\\=\frac{6}{12}\\\\=\frac{1}{2}\\\\=0.50[/tex]
Thus, the value of E [Z] is 0.50.

In the statistic department of UCI, there are 60 graduate students in total, 45 PhD students and 15 master students. Among master students, 40% of them are international students. Among PhD students, 20% are international students. (a) What is the proportion of international students in the statistic department? (b) What is the proportion of master students among all domestic students.
Answer:
(a) The proportion of international students in the statistic department is 25%.
(b) The proportion of master students among all domestic students is 20%.
Step-by-step explanation:
The following can first be obtained from the question:
Total number of graduate students = 60
Number of PhD students = 45
Number of Master students = 15
Percentage of international students among the master students = 40%
Percentage of international students among the PhD students = 20%
Number of international master students = Number of Master students * Percentage of international students among the master students = 15 * 40% = 6
Number of international PhD students = Number of PhD students * Percentage of international students among the PhD students = 45 * 20% = 9
The questions can now be answered as follows:
(a) What is the proportion of international students in the statistic department?
This can be calculated as follows:
Total number of international students = Number of international master students + Number of international PhD students = 6 + 9 = 15
Total number of graduate students = 60
Proportion of international students in the statistic department = Total number of international students / Total number of graduate students = 15 / 60 = 0.25, or 25%
Therefore, the proportion of international students in the statistic department is 25%.
(b) What is the proportion of master students among all domestic students.
This can be calculated as follows:
Total number of graduate students = 60
Total number of international students = Number of international master students + Number of international PhD students = 6 + 9 = 15
Total number of domestic students = Total number of graduate students - Total number of international students = 60 - 15 = 45
Number of Master students = 15
Number of international master students = Number of Master students * Percentage of international students among the master students = 15 * 40% = 6
Number of domestic master students = Number of Master students - Number of international master students = 15 - 6 = 9
Proportion of master students among all domestic students = Number of domestic master students / Total number of domestic students = 9 / 45 = 0.20, or 20%
Therefore, the proportion of master students among all domestic students is 20%.
what is the square root of 20
Answer:
It is 4.472135955, which simplifies to 4.47
Step-by-step explanation:
Step-by-step explanation: The square root of 20 is not a perfect square.
In other words, it's impossible to find a whole number
times itself that gives us a product of 20.
However, we can simplify it.
20 breaks down into 2 x 10 and 10 breaks down into 2 x 5.
Since the 2's pair up as factors of 20, a 2 comes out of the radical.
Since the 5 doesn't pair up, it stays inside.
So our answer is 2√5.

Step-by-step explanation:
A company buys a machine for $275,000 that depreciates at a rate of 10% per year. Find a formula for the value of the machine after n years. What is its value after 5 years?
Answer:
The formula is;
V = 275,000(0.9)^n
The value of the machine after 5 years is $162,384.75
Step-by-step explanation:
Here, we want to find the formula for the value of the machine after n years
Mathematically, we can use an exponential model for this
V = I ( 1 - r)^n
Where v is the value after n years
I is the value at which the machine was bought
r is the depreciation percentage ; 10% = 10/100 = 0.1
n is the number of years
Thus;
V = 275,000(1 - 0.1)^n
V = 275,000(0.9)^n
The value of the machine after 5 years will be;
V = 275,000(0.9)^5
V = 162,384.75

Answer:
q = -2
Step-by-step explanation:
Constant = whole number
If the two lines are parallel the slopes would be equal.
So if the first line is y = -2x + 5/3
The the second line would become y = -2x + 6.
If q becomes -2, it will be a constant and the two lines will also be parallel
