Bogdan [553]

Answer:

<em>The probability is 0.89 or 89%</em>

Step-by-step explanation:

<u>Probability</u>

There are n=27 students in a certain Algebra 2 class. 18 out of them play basketball and 16 of them play baseball.

We also know 3 students play neither sport. This leaves 27-3=24 students playing sports.

The probability that a randomly chosen student plays basketball or baseball is:

\displastyle p=\frac{24}{27}

Simplifying:

\displastyle p=\frac{8}{9}=0.89

The probability is 0.89 or 89%

Larry buys a tent that is on sale for 25% off the original price. The original price is $80 more than the sale price. What is th
myrzilka [38]

Answer:

The original price of the tent = $320

Step-by-step explanation:

Let the original price be =$ x

Discount offered  = 25% of the orignal price = \frac{25}{100}\times x=0.25\times x =\$ 0.25x

Original price is $80 more than sale price

Discount = Original price - Sale price = $80

So, we have

0.25x=80

We need to solve for x to find original price

Dividing both sides by 0.25

\frac{0.25}{0.25}x=\frac{80}{0.25}\\x=\$320

∴ The original price of the tent = $320
