I don’t know for sure but I think the answer is probably B.

A cylindrical tank with radius 5 m is being filled with water at a rate of 3 m3 ymin. How fast is the height of the water increa

Marizza181 [45]

The rate at which the height of the water in this cylindrical tank is increasing is 26.18 m/mn.

<h3>How to calculate the volume of a cylinder?</h3>

Mathematically, the volume of a cylindrical tank can be calculated by using this formula:

V = πr²h

Where:

h is the height.

r is the radius.

Differentiating with respect to h, we have:

dV/dt = πr²(dh/dt)

3 = 3.142 × 5² × dh/dt

3 = 78.55dh/dt

dh/dt = 78.55/3

dh/dt = 26.18 m/mn.

The math department at a small school has 5 teachers. The ages of these teachers are 23, 34, 37, 42, and 58. Suppose you select

denis23 [38]

The graph that shows the sampling distribution of the sample minimum age is; Option C Graph

<h3>Sampling distribution</h3>

We are given the ages of the 5 teachers as;

23, 34, 37, 42 and 58.

The options that show the sampling distribution of the sample minimum age has been attached.

Since 4 teachers will be selected out of the 5, it means that the minimum age of the 4 selected teachers will be 23 years of age 4 time while the minimum age will be 34 if the 23 year old teacher is not selected.

In conclusion, the sampling distribution for this scenario of minimum age should show 4 teachers at the 23 year mark and 1 teacher at the 34 year mark.
