Answer:135 serves
Step-by-step explanation:
Remember that 45%=45/100=0.45
So if the tennis player serves the ball 300 times, and 45% cannot be returned, then we can use the following expression to solve for the answer:
300*0.45=135serves
Answer: 135 serves will not be returned
Answer with explanation:
The Curve given here is a probability density curve for a continuous random variable.
Area under the entire region of the curve = 1
Using the Standard normal table to obtain area occupied when Z values are given
Area of the normal curve, when ,Z =0.88, is =0.8106
Area occupied by normal curve ,when Z= -1.26, is =0.1038
So, Area of shaded Region
Option D:→ 0.7068
I used one of the statistical functions on my trusty TI-83 Plus calculator:
normcdf(-1.26, 0.88) = 0.707
Note that this is, as expected, between 0 and 1.
347.2 cm3
351.9 cm3
359.1 cm
372.4 cm
Answer:
Volume = 351.9cm³
Step-by-step explanation:
Volume of cylinder = πr²h
r = 4cm, h = 7cm, π = 3.142, volume = 347.2cm³
Volume = 3.142 × 4² × 7
Volume = 3.142 × 16 × 7
Volume = 351.90cm³
Volume = 351.9cm³

Answer:
B) 351.9 cm3
Step-by-step explanation:
351.9 cm3
V = πr2h
V = π(4)2(7)
V = π(16)(7)
V = 112π
V = 351.858
