We know that
[the circumference of a circle]=pi*D
D=circumference/pi-----------------> 28/pi-----------------> D=8.91 in

1 ft---------> 12 in
X ft--------> 8.91 in
X=8.91/12------> X=0.7425 ft

then
24/0.7425--------> 32.32 soccer balls

the answer is
33 balls soccer

To find the number of soccer balls that would be needed to cover the distance to the goal, you will need to find the diameter of the soccer ball.

To find the diameter use be formula for circumference to solve for the diameter.

C = pi x d
28 = 3.14 x d
d = 8.9 inches

The distance to cover is 24 feet, so convert to inches and divide by 8.9 inches.

24 x 12 = 288 inches
288/8.9 = 32.4 balls
You will need about 32 soccer balls to cover the distance.

A 99% confidence interval for the sugar content (per 5 oz. serving) of a shipment of strawberries is 5.9 to 8.3 grams.
gavmur [86]

Answer:

Sample mean = 7.1

Margin of error = 0.465

Step-by-step explanation:

Formula for confidence interval is;

CI = x¯ ± zE

Where;

x¯ is sample mean

z is critical value at confidence level

E is margin of error.

z for 99% Cl is 2.58

We are told the CI is 5.9 to 8.3.

Thus;

5.9 = x¯ - 2.58E - - - - (1)

8.3 = x¯ + 2.58E - - - - (2)

Add both equations together to get;

14.2 = 2x¯

x¯ = 14.2/2

x¯ = 7.1

Put 7.1 for x¯ in eq 1 to get;

5.9 = 7.1 - 2.58E

7.1 - 5.9 = 2.58E

E = 1.2/2.58

E = 0.465
