What is the distance between the points (-5, -2) and (3, 13)? if necessary, round your answer to two decimal places?

VikaD [51]

In order to find the distance between the two points we utilize the Pythagorean Theorem,: 
Distance = Square Root ( (X difference)^2 + (Y difference)^2 )
So we have
Square Root (-5 -3)^2 + (-2 -13)^2 =
Square Root -8^2 + -15^2 =
Square Root (64 + 225)
=17

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%

The local store where Tim shops charges a 7% sales tax for clothing. Complete the table by figuring the cost of the jeans after

Sindrei [870]

Answer:

$A=P+P\times S\%$

Step-by-step explanation:

For calculating the sales tax of a product, it is required to first multiply the original cost price of the product by the sales tax percentage.

Once the sales tax has been computed add it to the original cost price in order to determine the total cost of the product.

The formula of final amount is:

$A=P+P\times S\%$

Here,

A = final amount

P = original cost price

S = sales tax percentage

371 + 18x ≥ 566 solve for X

Andru [333]

$18x \geqslant 566 - 371 \\ 18x \geqslant 195 \\ \frac{18x}{18} \geqslant \frac{195}{18} \\ x \geqslant 10.8333333333$

YOU CAN EVEN WRITE IT IN THE FRACTION FORM .

BE REMINDED THAT <> CHANGE SIGN WHEN YOU DIVIDE OR MULTIPLY A NEGATIVE NUMBER ONLY.
