We have been given a graph of a normal distributed data and we are asked to find the mean from our graph.

Since we know that a normal distribution is a bell shaped curve, perfectly symmetric around its center. The density curve is symmetric about mean. In a normal distribution mean, median and mode are equal.

We can see from our graph that our graph is symmetric about 4. The center of graph is 4, therefore, mean of our data is 4.

If a sentence is defined recursively by f(0)=3 and f(n+1) = f(n) +5 for n ? 0, then f(2) is A) 2 B) 3 C) 5 D) 8
VladimirAG [237]

The recursive formula f(n+1)=f(n)+5 means that the next term in the sequence is 5 more than the previous one.

So, we know that we start from f(0)=3, which means that the next term is

f(1) = f(0)+5 = 3+5 = 8

Similarly,

f(2) = f(1)+5 = 8+5 = 13

What is the volume of the composite figure?
Sladkaya [172]

Answer:

748 in^3.

Step-by-step explanation:

This consists of a triangular prism and a  rectangular cuboid .

Volume of the prism =  .1/2 * 8 *11 * 17 = 748 in^3

Volume of the cuboid =  5*8*17 = 680 in^3

Therefore the volume of the whole figure

= 680 + 748 =  1428 in^3.
