Answer:1695.75

Step-by-step explanation:

We know that there are 7 days in a week. Since 57 people rent skates each day, we know that 57*7=399 skates are rented each week. Since one skate cost 4.25, we know that 399*4.25 is the cost, which is 1695.75. (If you are not allowed to use a calculator, you can do 400*4.25-4.25, to make it easier to compute)

borishaifa [10]

Step-by-step explanation:

9 -  \frac{x}{5}  = 3 \\ 9 - 5 \times  \frac{x}{5}  = 3 \times 5 \\ 9 - x = 15 \\  - 9 - x =  - 9 + 15 \\  - x = 6 \\  - x \div  - 1 = 6 \div  - 1 \\ x =  - 6

Mason has 108 feet of material to build a fence around a rectangular pool on his property. If the width of the fence must be 6 f
Vlad1618 [11]

Answer:

Option A (48 yards).

Step-by-step explanation:

The perimeter of any shape other than the ellipse is given by:

Perimeter = Sum of all sides.

Since there are two pairs of lines and both lines in the pair are congruent in each other in a rectangle, the formula can be updated as:

Perimeter of a rectangle = 2L + 2W; where L is the length and W is the width.

The perimeter of the fence around the rectangular pool is 108 feet and the width of the pool is 6 feet. The length can be calculated by plugging in the values in the above equation:

108 = 2L + 2(6).

2L = 108 - 12.

L = 96/2.

L = 48 feet.

So Option A is the correct answer!!!

Twenty-five percent of the customers entering a grocery store between 5 P.M. and 7 P.M. use an express checkout. Consider five r
steposvetlana [31]

Answer:

The required probability = 0.2637

Step-by-step explanation:

Let X represents the no of customers that uses the express checkout.

X \sim Binomial (n =5, p= 0.25)

The probability mass function is given by:

P(X =x) = \dfrac{5!}{x!(5-x)!}(0.25)^x (1-0.25)^{5-x} \ \ ; for \ x =0,1,2,3,4,5

To find:

P(X =2) = \dfrac{5!}{2!(5-2)!}(0.25)^2 (1-0.25)^{5-2} \ \

P(X =2) = \dfrac{5!}{2!(3)!}(0.25)^2 (0.75)^{3} \ \

P(X =2) = \dfrac{5\times 4 \times 3!}{2!(3)!}(0.25)^2 (0.75)^{3}

P(X =2) = \dfrac{20}{2!}(0.25)^2 (0.75)^{3}

P(X = 2) = 0.2637

Thus, the required probability = 0.2637
