Answer:
a) 54 mph to 144 mph
Step-by-step explanation:
We don't know the shape of the distribution, so we use Chebyshev's Theorem to solve this question. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
At least eight-ninths of the player's serves.
8/9 is approximately 89%
So
Mean: 99, standard deviation: 15
99 - 3*15 = 54
99 + 3*15 = 144
So the correct answer is:
a) 54 mph to 144 mph
Answer: Approximately 52.87 cm.
Step-by-step explanation:
Circumference is diameter times pie to divide the circumference by pie.
166/3.14 use 3.14 as an approximation for pie.
166/3.14 = 52.87 rounded to the nearest hundredth
Answer: Yes because if you add 4 squared and 7 squared you get 65. The if you use square root with 65 you will get 8.06225774. Simplify that and you get 8

Answer:
$11,025
Step-by-step explanation:
April: 150hrs
May-August: 200hrs x 4 = 800 hrs
September: 100 hrs
$10.50/hr pay rate
150+800+100 = $1,050
$1,050 x $10.50 = $11,025
*Gross pay is the amount of money made before tax
