Makes 25 dollars an hour and gets a 10% raise

1 answer:

3 0

To find the current salary, we take 10% of $25 (the raise), then add it back into the current salary.

Current salary = (25×10%) + 25

= (25 × .10) + 25
= 2.50 + 25
= $27.50

So his raise was 2.50 and he now makes $27.50

Answer:

0.6708 or 67.08%

Step-by-step explanation:

Helen can only make both free throws if she makes the first. The probability that she makes the first free throw is P(C) = 0.78, now given that she has already made the first one, the probability that she makes the second is P(D|C) = 0.86. Therefore, the probability of Helen making both free throws is:

$P(C+D) = P(C) *P(D|C) = 0.78*0.86\\P(C+D) = 0.6708$

There is a 0.6708 probability that Helen makes both free throws.

It seems appropriate to use the linear regression function of your calculator for this. Looking at the data, you know the slope is generally positive, so only the 1st and 3rd choices are potentially viable.

A calculator shows the correlation coefficient (r) rounds to 0.816, so the appropriate selection is ...
