Due to concerns about the underinflation of footballs, the National Football League (NFL) created a series of standards that mus

t be met for the weight, length, and the long and short circumferences of each ball. It is stated that the balls are to be inflated to between 12.5 to 13.5 pounds. The pressure output by the ball pump is approximately Normal with a mean of 13 pounds and a standard deviation of 0.25 pounds. At each game, the home team must supply 12 balls to the referee 2 hours and 15 minutes prior to the start of the game for inspection.
(a) What is the probability that a randomly selected ball will not meet the inflation specifications?

A new cookie cake company is offering a
gtnhenbr [62]

Answer:

200.96in^2

Step-by-step explanation:

If the 1st cookie cake is 8" for its diameter and the 2nd cookie cake will have twice the length diameter of the 1st cookie cake .You will do 2 × 8 to get the diameter of the 2nd cookie cake.

First cookie cake diameter is 8".

Second cookie cake's diameter is 16".

Since we need the radius to find the area of the 2nd cookie cake we're going to do 16 / 2 which equals 8 so 8 is the radius.

A=(pi)r^2

A=(pi)8^2 *to the 2nd power means times by the same number

A=(pi)64

A= (3.14)(64)

A=200.96

=200.96^2

pi= 3.14 *for this problem

(4, -3), (x, 1); slope -4
Alexandra [31]

Answer:

x = 3

Step-by-step explanation:

m =  \frac{y \frac{}{2}  - y \frac{}{1} }{x \frac{}{2}  - x \frac{}{1} }

m = slope

x, y = coordinates

- 4 =  \frac{1 - ( - 3)}{x - 4} \\  - 4(x - 4)   = 1 + 3 \\  - 4x  + 16 = 4 \\  - 4 x = 4 - 16 \\  - 4x =  - 12 \\  x=  \frac{ - 12}{ - 4}  \\ x = 3
