-2 is the answer when i figured out the problem
yup the answer would be c have a nice day :)
The average score is 500 points and the standard deviation is 50 points.Mean - 2 SD = 500 - 2 * 50 = 500 - 100 = 400It means that more than 400 on the standardized test is more than: Mean - 2 Standard deviations.For the Normal distribution: 100% - 2.5 % = 97.5% = 0.975.Answer: The probability that student scores more than 400 points is 0.975.
Answer:
The force the player hit the ball with is 900 N
Step-by-step explanation:
Given;
mass of the baseball, m = 0.75 kg
acceleration of the ball, a = 1200 m/s²
The force the player hit the ball with is given by the following equations;
F = ma (based on Newton's second law of motion)
where;
F is the applied force
m is mass of the baseball
a is the acceleration of the baseball
F = ma
F = (0.75 x 1200)
F = 900 N
Therefore, the force the player hit the ball with is 900 N
, then
.
