Step-by-step explanation:
The times that a cashier spends processing individual customers' orders are independent random variables with mean 3.5 minutes and standard deviation 3 minutes. Find the number of customers n such that the probability that the orders of all n customers can be processed in less than 2 hours, is approximately 0.1. (Round your answer to the nearest integer.)
Answer:
26 customers
Step-by-step explanation:
First: determine the z score from standard normal probability table with an indicative area of 0.1
Z-score from probability table = - 1.28
mean = 3.5 minutes
std = 3 minutes
next determine the Z-score based on the information given in the question
Z = ( std - mean ) / processing time
= ( 3 - 3.5 ) / 2 = -0.25
Finally determine the number of customers
N = [tex](\frac{-1.28}{-0.25} )^2[/tex] = 1.6384 / 0.0625 = 26.21 ≈ 26 customers
Charlotte has 30 beads. She has 8 more red beads than blue beads. Which equation represents this situation? Please help :(
Answer:
The second answer choice is right
Step-by-step explanation:
Evaluate f(x) = 2x - 7 when x = 8.
Answer:
9
Step-by-step explanation:
Substitute 8 in place of x
f(x) = 2*8-7
f(x) = 9
Answer:
9
Step-by-step explanation:
plug in 8 where x is so it would look like
2(8)-7 = 9
do 2 *8 first which is 16
then do 16-7 which gives you 9
90 POINTS: What is the slope of the line in the correct graph? What is the slope of the line in the incorrect graph? Are the slopes the same or different? First is correct, Second isn't
Answer:
Correct graph
[tex]slope \frac{(175 - 105)}{(9 - 2)} \\ = \frac{70}{7} \\ = 10[/tex]
Incorrect graph
[tex]slope = \frac{(175 - 105)}{(8 - 2)} \\ = \frac{70}{6} \\ = 11.7[/tex]
Slopes are not the same
The slope of the correct graph is 10 and the slope of the incorrect graph is 11.7. The slopes of both graphs are different.
Slope formula = [tex]y_{2}-y_{1} / x_{2}-x_{1}[/tex]
Writing the equation in correct graph:
Slope = 175 - 105 / 9 - 2
⇒ 70 / 7
⇒ 10
Slope of correct graph is 10.
Writing the equation in incorrect graph:
Slope = 175 - 105 / 8 - 2
⇒ 70 / 6
⇒ 11.7
Slope of incorrect graph is 11.7 .

3. Is XY Tangent to circle Z?
Y
12 X
(20
Z
18
Answer:
XY is a tangent
Step-by-step explanation:
Given
[tex]XY = 12[/tex]
[tex]WY = 20[/tex]
[tex]WZ = 8[/tex]
Required
Is XY a tangent?
XY is a tangent if:
[tex]WY^2 = XY^2 + WX^2[/tex]
Because XY should make a right angle at point X with the circle
Where
[tex]WX = 2 * WZ[/tex]
So, we have:
[tex]WY^2 = XY^2 + WX^2[/tex]
[tex]WY^2 = XY^2 + (2*WZ)^2[/tex]
[tex]WY^2 = XY^2 + (2WZ)^2[/tex]
[tex]WY^2 = XY^2 + 4WZ^2[/tex]
This gives:
[tex]20^2 = 12^2 + 4*8^2[/tex]
[tex]400 = 144 + 256[/tex]
[tex]400 = 400[/tex]
Yes, XY is a tangent
Twice a number , subtracted from 60 is 20. Find the number
Answer:
The number is 20.
Step-by-step explanation:
60 - 2y = 20
- 2y + 60 = 20
- 2y + 60 - 60 = 20 - 60
- 2y = - 40
- 2y ÷ - 2 = - 40 ÷ - 2
y = 20

Given g(x) = -x + 5, solve for x when g(x) = 0
Answer:
x = 5
Step-by-step explanation:
Given g(x) = - x + 5 and g(x) = 0 , then equate the right sides
- x + 5 = 0 ( subtract 5 from both sides )
- x = - 5 ( multiply both sides by - 1 )
x = 5
