Answer:
The probability that the average score of the 49 golfers exceeded 62 is 0.3897
Step-by-step explanation:
The average score of all golfers for a particular course has a mean of 61 and a standard deviation of 3.5
We are supposed to find he probability that the average score of the 49 golfers exceeded 62.
Formula :
Refer the z table for p value
p value = 0.6103
P(x>62)=1-P(x<62)=1-0.6103=0.3897
Hence the probability that the average score of the 49 golfers exceeded 62 is 0.3897
Answer:
B.) 162 miles
Step-by-step explanation:
It really helps to draw a model when you are working with these. After having drawn a model, you can see that a right triangle was made, with the distance from Sameer's house to his cousin's being the hypotenuse. So, you can use the Pythagorean theorem:
Solve for c. Fill in values:

Answer:
5.25 seconds
Step-by-step explanation:
The vertex of the parabola defined by ax²+bx+c is located at x = -b/(2a).
The time to maximum altitude is ...
x = -(168)/(2(-16)) = 168/32 = 5.25
The time at which maximum height is reached is 5.25 seconds after launch.
