Last night, a basketball team made 12 shots. If their shooting percentage is 75%, how

kvv77 [185]

Answer:

16 shots

Step-by-step explanation:

Start by making a proportion.

We know that 75% is the same as 3/4.

The 12 lines up with the 3 because it is shots made, not total shots.

So now, the proportion should look like this: $\frac{12}{x} =\frac{3}{4}$

Cross multiply.

12 x 4 = 48

3 x x = 3x

Set equal and solve for x.

3x = 48

48 / 3 = 16

16 = x

The Ray family went out to dinner The price of the meal was $38.95 The sales tax was 7% of the price of the meal. The tip was 18

Andrews [41]

Answer:

$49.18

Step-by-step explanation:

Dinner cost $38.95 before tax and tip are included.

Directions say to ADD 7% tip first so,

38.95 multiplied by 7%= 2.7265, Round up to $2.73

ADD $38.95 and $2.73 tax= $41.68

Now, multiply $41.68 by 18% to find the tip amount

$41.68 * 18%= 7.5024, Round to $7.50

ADD $41.68 and $7.50 to get answer: $49.18

Answer:

"34,814" is the correct solution.

Step-by-step explanation:

The given values are:

Intercept coefficient,

$\beta_0 = 23,859$

Production coefficient,

$\beta_1 = 3.13$

Units sold,

x = 3,500

Now,

The total cost will be:

⇒ $\bar{y}=\beta_0+\beta_1 x$

On substituting the estimated values, we get

⇒ $=23,859+3.13\times 3,500$

⇒ $=23,859+10,955$

⇒ $=34,814$
