Answer:
C.
Step-by-step explanation:
The random variable W is Normal, with a mean of 28 ounces and a standard deviation of four ounces.
mean of total = 7+7+7+7 = 28
Variance of total = 4+4+4+4 = 16
SD of total = sqrt(16) = 4
The expression that shows the surface area of the pyramid is (2 * 2) + 4(0.5 * 2 * 3)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The surface area of pyramid = sum of individual area of the surface
Surface area = (2 * 2) + 4(0.5 * 2 * 3)
The expression that shows the surface area of the pyramid is (2 * 2) + 4(0.5 * 2 * 3)

Answer:
f(x) = 7 sec(x)
Step-by-step explanation:
The range of the function is less than -7 or greater than 7. So the midline is y=0 and the amplitude is 7.
There are two asymptotes per period, so the period of the function is 2π.
Therefore, the function is:
f(x) = A sec(2π / T x)
f(x) = 7 sec(2π / (2π) x)
f(x) = 7 sec(x)
Answer:
x <40
Step-by-step explanation:
The income from the pens is 2*x
He made less than 80
2x <80
Divide each side by 2
2x/2 < 80/2
x < 40
