Elza [17]

Answer:

P(X

And we can find this probability using the normal standard distribution table and we got:

P(z

And the percentage faster than 13.28 seconds would be 91.9%

Step-by-step explanation:

Let X the random variable that represent the runtimes of a population, and for this case we know the distribution for X is given by:

X \sim N(13,0.2)  

Where \mu=13 and \sigma=0.2

We want to find this probability:

P(X

And we can use the z score formula given by:

z=\frac{x-\mu}{\sigma}

Using this formula we have:

P(X

And we can find this probability using the normal standard distribution table and we got:

P(z

And the percentage faster than 13.28 seconds would be 91.9%

What does "Classify the polynomial by the number of terms" mean
soldier1979 [14.2K]

"Classify the polynomial by the number of terms" means a term contains both the variables and its coefficient. For example a "monomial" has one term like 2x^{2}.

A binomial has 2 terms like 3x^{2}+6x

A trinomial has 3 terms like 4x^{2}+5x-8

And a polynomial has 4 or more terms.

So basically one can classify the type of polynomial by counting the number of terms in a given equation.

AlladinOne [14]

Answer:

He earn $535.00 in the 5% account

Step-by-step explanation:

I =  \frac{prt}{100}

I = interest amount

p = $10 700

r = 5%

t = 1 year

I = (10700×5×1)/100

= $535.00
