Answer:

POLYNOMIAL is a 10-letter word

Step-by-step explanation:

A polynomial is such an expression.

Virtually any kind of algebraic expression is made by adding or subtracting terms, grouping them, applying functions to them, or dividing them. (A term is already a product; increasing the number factors doesn't change that.)

A polynomial is a special kind of sum-of-terms expression involving terms that are non-negative integer powers of a variable.

The length of time before a seed germinates when falling on fertile soil is approximately Normally distributed with a mean of 60

PIT_PIT [208]

Answer:

b. 0.12

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 600, \sigma = 100$

What is the probability that a seed will take more than 720 hours before germinating?

This is 1 subtracted by the pvalue of Z when X = 720. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{720 - 600}{100}$

$Z = 1.2$

$Z = 1.2$ has a pvalue of 0.88.

1 - 0.88 = 0.12

So the correct answer is:

b. 0.12

Which is another way to write 42+63

zysi [14]

21+21+31.5+31.5 over here we split both of the numbers in half, creating a different way of writing the equations!
or the easier way would be:
63+42 All we did here was switch the numbers to create the same equation in the opposite form!
