Answer:
D . 0.4
Step-by-step explanation:
let the height be the y coordinate
let the width be the x coordinate
first point :
width/x : 0.5
height/y : 0.8
according to the formula given:
height = constant/width :
so:
0.8 = constant/0.5
constant = 0.4
next point:
x : 0.8
y : 0.5
0.5 = constant/0.8
constant = 0.4
for all of the points, the constant is 0.4
If L = length of each edge the
L^3 = 231
L = 6.136 in^3 to the nearest thousandth

Answer:
Step-by-step explanation:
Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test reults
µ = mean score
σ = standard deviation
From the information given,
µ = 1700 points
σ = 75 points
We want to the probability that a student will score more than 1700 points. This is expressed as
P(x > 1700) = 1 - P(x ≤ 1700)
For x = 1700,
z = (1700 - 1700)/75 = 0/75 = 0
Looking at the normal distribution table, the probability corresponding to the z score is 0.5
P(x > 1700) = 1 - 0.5 = 0.5
