Step-by-step explanation:
Z - score
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Calculate the Z value for the next car that passes through the checkpoint will be traveling slower than 65 miles per hour.
This is Z when X = 65. So

Answer:
1,530
Step-by-step explanation:
box 1 (left one): 10*9*9=810
box 2 (right one): 18*4*10=720
720+810=1,530
Answer:
1530 cm^3
Step-by-step explanation:
They are two Rectangular Prism.
prism 1.
length l = 18 cm
width w = 10 cm
height h = 4 cm
diagonal d = 20.976177 cm
total surface area S_tot = 584 cm^2
lateral surface area S_lat = 224 cm^2
top surface area St_op = 180 cm2
bottom surface area S_bot = 180 cm^2
volume V = 720 cm^3
Prism 2.
length l = 10 cm
width w = 9 cm
height h = 9 cm
diagonal d = 16.1864141 cm
total surface area S_tot = 522 cm^2
lateral surface area S_lat = 342 cm^2
top surface area Stop = 90 cm^2
bottom surface area Sbot = 90 cm^2
volume V = 810 cm^3
Add 720 cm^3+810 cm^3 = 1530 cm^3
Agenda: l = length
w = width
h = height
d = diagonal
S_tot = total surface area
S_lat = lateral surface area
S_top = top surface area
S_bot = bottom surface area
V = volume
Formula: Volume of Rectangular Prism: V = lwh

What is Scott's total pay if he doesn't sell any copies of History is Fun?
Answers
Answer:
A. $80
B. $2100
Step-by-step explanation:
Given:
80x+2100=y
Rewrite the equation
y = 80x + 2100
Where,
y = Scott's total pay (in dollars)
x = number of copies of History is Fun he sells
2100 = fixed pay
A.
Since, x = number of copies of History is Fun he sells
If x = 0
y = 80x + 2100
= 80(0) + 2100
= 0 + 2100
= 2100
y = $2100
If x = 1
y = 80x + 2100
= 80(1) + 2100
= 80 + 2100
= 2180
y = $2180
change in Scott's total pay for each copy of History is Fun he sells = $2180 - $2100
= $80
B. What is Scott's total pay if he doesn't sell any copies of History is Fun?
That is, when x = 0
y = 80x + 2100
= 80(0) + 2100
= 0 + 2100
= 2100
y = $2100

Answer:
well 660
Step-by-step explanation:
well frist we will have to subtract 408 with every other number
408-138=270
270-111=159
this is what he had left
but if it's the other way around 410+140+110=660
