Mr.Walden wrote the expression. He asked his students to write an equivalent expression of simplified form.

mafiozo [28]

Answer:

option D

Brianna

Step-by-step explanation:

Given in the question the expression wrote by Mr.Walden

$\frac{p^{-5} }{q^{0} }$

To write the simplified form of this expression we will use negative rule of exponent

$b^{-n}$ = 1 / $b^{n}$

$q^{-5} = \frac{1}{q^{5} }$

so,

$\frac{1}{q^{5} x q^{0} }$

$\frac{1}{q^{5} p^{0} }$

Only Brianna wrote right simplification of the expression written by Mr.Walden

Suppose babies born in a large hospital have a mean weight of 3316 grams, and a standard deviation of 324 grams. If 83 babies ar

Anuta_ua [19.1K]

Answer: 0.129

Step-by-step explanation:

Let $\overline{X}$ denotes a random variable that represents the mean weight of babies born.

Population mean : $\mu= \text{3316 grams,}$

Standard deviation: $\text{324 grams}$

Sample size = 83

Now, the probability that the mean weight of the sample babies would differ from the population mean by greater than 54 grams will be :

$P(|\mu-\overline{X}|>54)=1-P(\dfrac{-54}{\dfrac{324}{\sqrt{83}}}$

hence, the required probability = 0.129

mart [117]

Answer:

The duty he has to pay is 156.25$.

Step-by-step explanation:

We know that for foreign-made vehicles imported into the U.S., whether new or used, either for personal use or for sale, are generally dutiable at the following rates: Cars: 2.5%.

From task we know that the Fiat car abroad that cost him $6,250.

We have the following proportion:

$100:6250=2.5:x\\\\100x=2.5\cdot 6250\\\\100x=15625\\\\x=156.25\\$

The duty he has to pay is 156.25$.
