G(t)=t squared - 2; Find g(9)

GaryK [48]

Answer:

79

Step-by-step explanation:

So we have the function:

$g(t)=t^2-2$

To find g(9), substitute 9 for t. Thus:

$g(9)=9^2-2$

Square:

$g(9)=81-2$

Subtract:

$g(9)=79$

So, our answer is 79.

And we're done!

Hotels, like airline, often overbook, counting on the fact that some people with reservations will cancel at the last minute. A

agasfer [191]

Answer: The required probability is 0.334.

Step-by-step explanation:

Since we have given that

N = 15 reservations

probability of reservations will not be used = 0.2

probability of reservations will be used = 1-0.2=0.8

Let X be the Binomial variable,that the number of reservations canceled.

We need to find the probability that more than 8 but less than 12 reservations.

So, it becomes,

$P(8$

Hence, the required probability is 0.334.

Caroline babysat for two families - the Nelsons and the Smiths. Use the info below to compare her earnings.

algol13

Answer:

She earns $6.50 from the Smiths which is 25 cents more than she earns at the Nelsons.

Step-by-step explanation:

To solve this problem you must find the hourly rate she earns at the Smiths. This will allow you to compare to the hourly rate that is given for the Nelsons. To find the Smiths hourly rate divide $39 by the 6 hours she babysat there. This will have the hourly rate. 39/6=6.5. This means she earns $6.50 an hour for the Smiths. When comparing the rates it is clear that she earned 25 cents more at the Smiths.
