Answer:

No the school libary doesn not have enough pace for all the books. If the least amount of books came which is 15 books in all of 42 boxes (15*42), it would be 630 books and the school libary shelf can only hold 600 books becuase 10 shelves * 60 books on each shelf is 10*60 which is 600. If the least amount of books can’t even fit then the others wold defietnly not fit.

Shen took out a loan for 7600 that charges an annual interest rate of 8.2%, compounded monthly. Answer each part

velikii [3]

Step 1

Given;

$\begin{gathered} P=7600 \\ r=\frac{8.2}{100}=0.082 \\ t=1 \end{gathered}$

Step 2

A) she will owe

$\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ A=7600(1+\frac{0.082}{12})^{12\times1} \\ A=\text{ \$}8247.16 \end{gathered}$

B) The effective annual rate is given as;

$\begin{gathered} R=(1+\frac{i}{n})^n-1 \\ R=[(1+\frac{0.082}{12})^{12}-1]\times100 \\ R=0.08515\times100=8.515\text{\%} \\ R\approx8.52\text{\%} \end{gathered}$

On a track and field team, 8% of the members run only long-distance, 32% compete only in field events, and 12% are sprinters onl

kondor19780726 [428]

Answer:

0.40

Step-by-step explanation:

Members who run only long distance = 8%

So, probability that a member will run only long distance = P(A) = 0.08

Members who compete only in field events = 32%

So, probability that a member will compete only in field events = P(B) 0.32

Members who are sprinters = 12%

So, probability that a member is sprinter = P(C) 0.12

We have to calculate the probability that a randomly chosen team member runs only long-distance or competes only in field events. i.e we have to find P(A or B). Since these events cannot occur at the same time, we can write:

P(A or B) = P(A) + P(B)

Using the values, we get:

P(A or B) = 0.08 + 0.32 = 0.40

Thus, the probability that a randomly chosen team member runs only long-distance or competes only in field events is 0.40

The Table below gives you The population of Texas since 1970. Find the average rate if change from 1970 to 1090

ruslelena [56]

Answer:

Average rate of change = 0.29 million per year

Step-by-step explanation:

Average rate of change in the population from year 1970 to year 1900 is given by the formula,

Average rate of change = $\frac{\text{Population in year 1990-Population in year 1970}}{1990-1970}$

= $\frac{17-11.2}{1990-1970}$

= $\frac{5.8}{20}$

= 0.29 million per year

Therefore, average rate of change in the population from 1970 to 1990 will be 0.29 million per year.
