Z-score for a variable X is calculated using
Z(x)=(x-mean)/standard deviation.
Here
x=56
mean=65
standard deviation=5
so
Z(65)=(65-56)/5=9/5=1.8
Answer:
4 inches should be turned up on both sides.
Step-by-step explanation:
In order to find this, create a situation in which we give the amount turned up on each side as x. Then give the amount that isn't turned up as 16 - 2x (since 2x is the amount turned up). Now we can find the area by multiplying the 3 measurements.
100 * x * (16 - 2x) = MAX
100 * (16x - 2x^2) = MAX
-200x^2 + 1600x = MAX
Now that we have a quadratic function, we can find the maximum value of x by using the vertex formula for x values (-b/2a).
x = -b/2a
x = -1600/2(-200)
x = -1600/-400
x = 4
Answer:
D : -5 ≤ x < 1
R : -4 ≤ y < 7
Step-by-step explanation:
In a graph, domain is always represented by the x-axis while the range is represented by the y-axis.
In this diagram, at x-axis, the dots are connected by -5 and 1. At y-axis, the dots are connected by -4 and 7.

Answer:
3
Step-by-step explanation:
You're simply divided each number by two
500/2= 250
250/2= 125
125/2= 62.5
62.5/2=?
