Paton knows she will make a selection from 36 total possible outcomes. Which statement might describe what Paton is doing? Check all that apply.

Answer: All but statement 1

Step-by-step explanation:

In order to get 36 as an outcome, the numbers need to multiply together in order to get 36. In other words, a*b*c*d*....= desired outcome number. In statement 1, 3*9=27, and therefore not 36 outcomes. The rest do multiply to 36.

Answer:

2,3,4,5

The value of a house is $165,000 and it loses 4% of its value every year. A. Use the exponential decay formula below to write a function for the home's value, y, after t years.

y=A(1±r)^t

B. Now use your formula to find the value of the home after 20 years. Round to the nearest dollar.

1)Y=165000(1-0.04)^t

2)y=165000(1-0.04)^20=?? Use the calculator

2)y=165000(1-0.04)^20=?? Use the calculator

Joe has finished 14 of the 30 lessons in his piano book. Lindsey has finished the same percent of lessons from her piano book, but her book contains 45 lessons. How many lessons has Lindsey finished?

Answer:

Lessons has Lindsey finished = 21

Step-by-step explanation:

It is given that,

Joe has finished 14 of the 30 lessons in his piano book. Lindsey has finished the same percent of lessons from her piano book, but her book contains 45 lessons.

To find the percentage of lessons of Joe

Percentage = (14*100)/30 = 140*3 = 46.67%

To find the lessons has Lindsey finished

Lindsey has finished the 46.67% of lessons from her piano book

46.67% of 45 = (46.67*45)/100 = 2100/100 = 21

Therefore lessons has Lindsey finished = 21

Answer:

Step-by-step explanation:

14 is 46.67% of thirty so you’d need to find out what 46.67% of 45 is which would be 21

Hope this is right and it helped XD

A junior basketball has a diameter of approximately 7 in., and a regulation basketball has a diameter of approximately 9.5 in. about how many times as great is the volume of the regulation basketball as the volume of the junior basketball?

Scale factor = 9.5 / 7

the ratio of the volumes will be 9.5^3 / 7^3

= 2.5 to nearest thousandth

So the volume the regulation ball is 2.5 times the volume of the junior one.

the ratio of the volumes will be 9.5^3 / 7^3

= 2.5 to nearest thousandth

So the volume the regulation ball is 2.5 times the volume of the junior one.

4. The cosine function can be made to have the same values as the sine function for each angle by including a shifted _______ in the calculation. A. amplitude

B. wavelength

C. period

D. phase

Answer: Option D

phase

Step-by-step explanation:

By definition, the cosine function has the following form

Where is known as the phase angle

By definition the sinx function is equal to the cosx function with a phase shift of

So if we have the function

and we want to transform it into the function then

Finally

the answer is the option D
