Navid had $72 in her savings account.

Fofino [41]

Answer:

9 weeks.

Step-by-step explanation:

First, find how many dollars Navid needs to save.

288-72= 216

Then, divide how much money that is needed by the number of dollars that are saved per week.

216/24= 9

Then tie it up into an equation:

(288-72)/24= x

x=9

What is the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings

Sophie [7]

Answer:

the experimental probability is 70%

Step-by-step explanation:

PLEASE HELP, TIMEDThe table shows the results of a survey in which 10th-grade students were asked how many siblings (brothers and/or sisters) they have.

What is the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings?

To the nearest whole percent, the experimental probability is

a. 65%.

b. 70%

c. 75%

d. 80%

We are given to find

the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings

we know that

probability = ( number of favourable outcomes)/ ( total possible outcomes)

a 10th-grade student chosen at random has at least one, but no more than two, siblings

so, there can be one or two siblings

so, total number of such students =18+10=28

Number of favourable outcomes =28

total number of students =4+18+10+8=40

so, total favourable outcomes =40

now, we can find probability

$p=\frac{28}{40}\\\\p=\frac{28}{40}\times 100\\\\p=70$

So,

Therefore, the experimental probability is 70%
