In simple words, The question is asking us to find the Slope of the given line...
[tex] \boxed{ \sf \: m = \frac{rise}{run} = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } }[/tex]
The letter m represents slopeTo find the slope, We need to take two point and then identitify x1, x2, y1, y2
(3,-4)(-1,8)Now,[tex] \tt \: m = \frac{8 - ( - 4)}{ - 1 - 3} [/tex]
[tex] \tt \: m = \frac{8 + 4}{ - 4} [/tex]
[tex] \tt \: m = \frac{12}{ - 4} [/tex]
[tex] \boxed{ \bf \: slope = - 3}[/tex]
Solution:
Note that:
Slope = Rise/RunRise and Run stated in pictureStep-1: Pick and two points on the line.
My chosen points are: (0,5) and (2,-1)Step-2: Use the formula y₂ - y₁/x₂ - x₁:
y₂ - y₁/x₂ - x₁ = Slope=> -1 - 5/2 - 0 = Slope=> -6/2 = Slope=> -3 = SlopeThe slope of the line is -3.
Suppose Abby tracks her travel time to work for 60 days and determines that her mean travel time, in minutes, is 35.6. Assume the travel times are normally distributed with a standard deviation of 10.3 min. Determine the travel time
such that 26.11% of the 60 days have a travel time that is at least
.
You may find this standard normal distribution table or this list of software manuals useful. Give your answer rounded to two decimal places.
Using the normal distribution, it is found that the the travel time such that 26.11% of the 60 days have a travel time that is at least is of 42.19 minutes.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of [tex]\mu = 35.6[/tex].The standard deviation is of [tex]\sigma = 10.3[/tex].The travel time such that 26.11% of the 60 days have a travel time that is at least X when Z has a p-value of 1 - 0.2611 = 0.7389, hence X when Z = 0.64, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.64 = \frac{X - 35.6}{10.3}[/tex]
[tex]X - 35.6 = 0.64(10.3)[/tex]
[tex]X = 42.19[/tex]
The travel time such that 26.11% of the 60 days have a travel time that is at least is of 42.19 minutes.

Solve for x and y.
x
128°
у
Answer:
y88 porty forty
YoungBoy
Answer:
x = 52°
y = 128°
Step-by-step explanation:
This is an isosceles trapezoid as the legs are the same length (denoted by the double dashes).
For an isosceles trapezoid, the sets of angles adjoined by parallel lines are equal. Therefore, for this trapezoid, y = 128 and the two remaining angles are both x.
The interior angles of a trapezoid = 360°
Therefore, x + x + 128 + y = 360
Since we know y = 128:
2x + 128 + 128 = 360
⇒ 2x = 104
⇒ x = 104 ÷ 2 = 52
7 times as much as the sun of 1/3and 4/5
Answer:
Step-by-step explanation:
First of all, you add 1/3 and 4/5, so you get:
To add 2 fractions, they need to have the same denominator. Since 3 and 5 don't have a common factor, so you multiply 1/3 by 5, and 4/5 by 3, so you get:
Now, the two fractions got the same denominator, and you can add them by adding the numerators over the same denominator. (You don't add denominators in addition) so you get:
That's the sum of 1/3 + 4/5.
Now, they want the sum of the 2 fractions 7 times. So you multiply 17/15 by 7. And as you know, 7 = 7/1. So you get:
In multiplication no need to have the same denominator. You multiply nominators by nominators and denominators by denominators. So you get:
Since 119 and 15 don't have a common factor, so they can't be simplified.
So, the answer is 119/15.

Susan Marciano invested part of her 28,000 bonus in a fund that paid an 11% profit and invested the rest in stock that suffered a 5% loss. Find the amount of each investment if her overall profit was 2,920
a = amount that paid 11% profits
b = amount that lost 5% profits
we know that whatever those values are, a + b = 28000.
how much is 11% of "a"? well, (11/100) * a = 0.11a.
how much is 5% of "b"? well (5/100) * b = 0.05b.

O B. 3(x-2)(x - 5)
O C. 3x(x-2)(x-5)
O D. 3x(x-6)(x - 5)
B if not C, with the exponent of the coefficient
The factorization of the trinomial is A = 3 ( x - 2 ) ( x - 5 )
What is Factorizing?Brackets should be expanded in the following ways to factorize an expression
For an expression of the form A = a ( b + c ) , the expanded version is given by A = ab + ac, i.e., multiply the term outside the bracket by everything inside the bracket
For an expression of the form A = ( a + b ) ( c + d ) , the expanded version is given by A = ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second.
Given data ,
Let the expression be represented as A
Now , the value of A is
A = 3x² - 21x + 30 be equation (1)
On simplifying , we get
Taking 3 as the common factor of the expression , we get
A = 3 ( x² - 7x + 10 )
A = 3 ( x² - 2x - 5x + 10 )
On factorizing , we get
A = 3 ( x - 2 ) ( x - 5 )
Hence , the expression is A = 3 ( x - 2 ) ( x - 5 )

[tex]-\frac{4}{5}x+ \frac{3}{10} < \frac{8}{10}[/tex]
subtract 3/10 from both sides: [tex]-\frac{4}{5}x < \frac{5}{10}[/tex]
Divide both sides by 4/5: [tex]-x < \frac{5}{8}[/tex]
Divide both sides by -1 (reverse sign): [tex]x > -\frac{5}{8}[/tex]
[tex]-\frac{4}{5x}+ \frac{3}{10} < \frac{8}{10}[/tex]
subtract 3/10 from both sides: [tex]-\frac{4}{5x} < \frac{5}{10}[/tex]

Answer:
51.
Step-by-step explanation:
When we use PEMDAS, we need to know what it stands for first. What it stands for will give us the steps necessary to complete and solve this problem.
PEMDAS stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
In this problem we do not have parenthesis or exponents, so we can go ahead and skip to multiplication. So:
8 x 18 ÷ 4 + 15
144 ÷ 4 + 15
Now we can go to doing division.
144 ÷ 4 + 15
36 + 15
Now we can do addition.
36 + 15
So, the answer is 51.

This is Linear Equation. The Sum of three numbers is 27. The second number is three times the first, while the third is twice the first, Find the average.
Answer:
average = 9
(the third number is the average)
Step-by-step explanation:
If the sum of three numbers is 27, then the average (mean) is the total (27) divided by the number of values (3):
⇒ 27 ÷ 3 = 9
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
However, if you want to find the actual numbers:
Let x = first number
Let y = second number
Let z = third number
Given:
The sum of three numbers is 27 ⇒ x + y + z = 27The second number is three times the first ⇒ y = 3xThe third number is twice the first ⇒ z = 2xSubstitute y = 3x and z = 2x into x + y + z = 27 and solve for x:
⇒ x + 3x + 2x = 27
⇒ 6x = 27
⇒ x = 4.5
y = 3x
⇒ y = 3 x 4.5
⇒ y =13.5
z = 2x
⇒ z = 2 x 4.5
⇒ z = 9
Therefore, x = 4.5 y = 13.5 and z = 9
which means z (the third number) is same value as the average

Ling Ling collected(587) stickers and Jia Jia collected 245 stickers. After giving 40 stickers to their cousin, they put the remainder equally into(36 boxes. How many stickers were there in each box?
Answer:
22 stickers in each box
Step-by-step explanation:
Ling Ling = 587 stickers
Jia = 245 stickers
Therefore, total number of stickers = 587 + 245 = 832
if they gave 40 stickers to their cousin, then
remaining stickers = 832 - 40 = 792
If they put the remaining 792 stickers equally into 36 boxes, then
number of stickers in each box = 792 ÷ 36 = 22
