121 of the green beans will be shorter than 13 centimeters.

First, we need to evaluate the expression below to find the z-score.
(13 - 11.2) / 2.1. = 0.86

The matching percent for this z-score is 0.8051.

Multiplying 0.8051 by 150 gives us about 121 green beans.

antoniya [11.8K]

Answer:

Wikipedia defines polynomials as "<em>an expression consisting of variables and coefficients</em>."

You would think that F(x) would not be a polynomial, but you could think of it like this:

F(x) = 0x + 1050

So, yes, I suppose constant terms by themselves are polynomials, it's just that they only have one term and would not really be called a <em>poly</em>-nomial.

You should probably research some more just in case.

Bess [88]

Answer:

y=7x-47

Step-by-step explanation:

y - 9 = 7x - 56 \\ y = 7x - 56 + 9 \\ y = 7x - 47

Lelu [443]
Hello! To find the answer to this, we must add all of the first 5 numbers. When you do that, the sum should be 81. You must do 16 * 6 to find the number of points combined he needs to add up to the average. 16 * 6 = 96. 96 - 81 = 15. On the 6th test, you must score 15 points to have an average of 16 points. The answer is 15.
