A 3
Andrew [12]

Answer:

There are (63) combinations. The notation means "six choose three". Out of six items (flavors) choose three.

(nk)=n!k!(n−k)!.

(63)=6!3!3!.

Think of it this way. There are 6 ways to choose a flavor. Once you choose, there are 5 ways to choose the next. After that, there are 4 flavors left. which is 6!/3!=6⋅5⋅4⋅3⋅2⋅13⋅2⋅1=6⋅5⋅4=120.

But, you could have chosen {chocolate,vanilla,strawberry} and you get the same combination as {vanilla, strawberry, chocolate} so we have to divide by 3!=3⋅2⋅1=6 to account for the order of choosing.

So the number of combinations of flavors is (63)=1206=20.

The area of the given parallelogram is 120.

Step-by-step explanation:

Step 1:

The parameters needed to determine the area of a parallelogram are the base length and height.

The base length of this parallelogram is 15 inches while its height is 8 inches.

The area of a rectangle is determined by multiplying the base length with the height.

Step 2:

The area of the parallelogram = (b)(h).

Here the base length is 15 inches and the height is 8 inches.

The area of the parallelogram =(15)(8) = 120.

So the area of the given parallelogram is 120.

Regression analysis was applied between sales data (in $1,000s) and advertising data (in $100s) and the following information wa
Darya [45]

Answer:

A. $66,000

Step-by-step explanation:

The relationship between sales data (in $1,000s) and advertising data (in $100s) is:

y=12+1.8x

If  if advertising is $3,000, then x =$30, and the point estimate for sales (in thousands of dollars) is:

y(30)=12+1.8*30\\y=66

Converting it to dollars, the point estimate for sales is:

S=1,000*66\\S=\$66,000
