Answer:

3.6%

Step-by-step explanation:

We are solving the above question, using the simple interest Formula:

I = PRT

Where

I = Interest = $9

P = Principal = $150

R = Interest rate = ??

T = Time in years = 20 months

We convert this to years

12 months = 1 year

20 months = x

x = 20/12

x = 1.67 years

Hence, making R the subject of the formula

R = I/PT

R = 9/150 × 1.67

R = 9/250.5

R = 0.0359281437

Converting to percentage

R = 0.0359281437 × 100

R = 3.59281437%

R = 3.6 %

The simple interest rate she is earning is 3.6%

Is the distance a baseball travels in the air after being hit a discrete random​ variable, a continuous random​ variable, or not
LuckyWell [14K]

Answer: a continuous random​ variable

Step-by-step explanation:

<u><em>Can you count the distance it traveled?</em></u> You can't, so it couldn't be discrete because you can count discrete variables.

<u><em>Can you measure the distance it traveled? </em></u>You sure can, that makes it a continuous random variable.

<u><em>Do you know the exact distance it's going to travel?</em></u><u> </u>You won't, therefore it's a random variable since you don't know the value beforehand.
