Answer:
the probability of a rating that is between 200 and 275 is 0.4332
Step-by-step explanation:
Given the data in the question;
if an applicant is randomly selected, the probability of a rating that is between 200 and 275
mean μ = 200
standard deviation σ = 50
P( 200 < X < 275 ) = P( X-μ / σ < x-μ / σ < X-μ / σ )
P( 200 < X < 275 ) = P( 200-200 / 50 < x-μ / σ < 275-200 / 50 )
= P( 0/50 < Z < 75/50 )
= P( 0.00 < Z < 1.50 )
P(Z < 1.50) - P(Z < 0.0)
from the standard normal table
P(Z < 1.50) = 0.9332
P(Z < 0.0) = 0.5000
so
P( 200 < X < 275 ) = 0.9332 - 0.5000
P( 200 < X < 275 ) = 0.4332
Therefore, the probability of a rating that is between 200 and 275 is 0.4332
Is $20.29 with $4 dollar shipping more, or is $23.09 with 3 dollar shipping more? Help please, ASAP! :(
Answer:
23.09 w/ 3 dollar shipping is more.
Step-by-step explanation:
20.29 + 4 = 24.29
23.09 + 3 = 26.09
hope this helps :)
Answer:
23.09 dollars and 3 dollar shipping is more than 20.29 with 4 dollar shipping
Step-by-step explanation:
if you add the shipping and price together 23.09 dollars and 3 dollar shipping is 26.09 in total
And the 20.29 with 4 dollar shipping is 24.29 in total
and 26.09 is greater than 24.29, so 23.09 dollars and 3 dollar shipping is more than 20.29 with 4 dollar shipping
Which of the following is the equation of a line perpendicular to the line y =
-10x+1, passing through the point (5,7)?
Answer: The answer is C.
Step-by-step explanation: This is because when you solve you get y=1/10x+6.5 this graph runs through the point (5,7) and is perpendicular to y=-10x+1. In order for two equations to be perpendicular their slopes will be the opposite.

30 kilograms of beans costs $5. How many kilograms of beans can you buy for $20?
Answer:
120 kg
the kilograms of beans which can by for $20 are
30*(20/5) = 30.4 = 120 (kg)
Answer: 120 kilograms
Step-by-step explanation:
We can buy 30 kilograms of beans for $5 dollars. We need to find how many kilograms of beans we can buy for $20.
The first step is to divide 20 by 5. Then, using the quotient, we can multiply it by 30 to see how many kilograms of beans we can buy for $20.
20 ÷ 5 = 4.
4 x 30 = 120.
Therefore, we can buy 120 kilograms of beans for $20.
Cool beans ;)
(25m + 22) + (9m) = ?
Answer:
Step-by-step explanation:
Simplifying
25m + 22 = 9m
Reorder the terms:
22 + 25m = 9m
Solving
22 + 25m = 9m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-9m' to each side of the equation.
22 + 25m + -9m = 9m + -9m
Combine like terms: 25m + -9m = 16m
22 + 16m = 9m + -9m
Combine like terms: 9m + -9m = 0
22 + 16m = 0
Add '-22' to each side of the equation.
22 + -22 + 16m = 0 + -22
Combine like terms: 22 + -22 = 0
0 + 16m = 0 + -22
16m = 0 + -22
Combine like terms: 0 + -22 = -22
16m = -22
Divide each side by '16'.
m = -1.375
Simplifying
m = -1.375

A line that includes the points (-9, h) and (-8, 9) has a slope of 10. What is the value of h?
Answer:
-1
Step-by-step explanation:
Use the rule y2-y1 / x2-x1
y1 = h
y2 = 9
x1 = -9
x2 = -8
so you get
9-h / (-8) - (-9) = 10
cross multiply to get
9-h = 10
so -h = 10-9
so h = -1

Given that L is a linear function, L (5) = 100 and L (9) = 150.
a. Determine the value of L (13)
Answer:
L(13) = 200
Step-by-step explanation:
Linear function:
A linear function has the following format:
[tex]y = mx + b[/tex]
In which m is the slope(how much y changes when x changes by 1) and b is the y-intercept(value of y when x = 0).
Finding the slope:
L (5) = 100 and L (9) = 150.
The slope is given by the change in the output(L, which is equals to y in the general formula) divided by the change in the input(x).
Change in the output: 150 - 100 = 50
Change in the input: 9 - 5 = 4
Slope: [tex]m = \frac{50}{4} = 12.5[/tex]
So
[tex]y = 12.5x + b[/tex]
L (5) = 100
So [tex]y(5) = 100[/tex], which means that when [tex]x = 5, y = 100[/tex], and we use this to find b.
[tex]y = 12.5x + b[/tex]
[tex]100 = 12.5*5 + b[/tex]
[tex]b = 100 - 12.5*5[/tex]
[tex]b = 37.5[/tex]
So
[tex]L(x) = 12.5x + 37.5[/tex]
a. Determine the value of L (13)
L when [tex]x = 13[/tex]. So
[tex]L(13) = 12.5*13 + 37.5 = 200[/tex]
