Answer: 3
Step-by-step explanation:
When a sphere is cut by a plane which passes through the center, it will create a circle that has the same diameter of the sphere.
To represent this area, you will use the formula for finding area of a circle.
A= pi x r^2
Pi x 5^2
A = 25 x pi or choice B
Answer:
False
Step-by-step explanation:
When you simplify 6/10 you will realize it's 3/5 which is not the same as 1/2.

Answer:
The acceleration of the drone is 2.6 m/s²
Step-by-step explanation:
The acceleration is the rate at which the speed changes over time, therefore to solve this question we must divide the change of speed by the elapsed time in order to find the accelaration of the drone in that period. We have:
a = (Vf - Vi)/dt
Where a is the acceleration, Vf is the final velocity, Vi is the initial velocity and dt is the elapsed time. We have:
a = (51 - 38)/5 = 2.6 m/s²
The probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753
First, we need to find the z-score and this is expressed according to the formula;
x is the sample space
is the mean value
is the standard deviation
Given the following parameters
Mean = $275,000
Standard deviation = $10,500
If the true mean is $273,000, then;
If the true mean is $277,000
This means that the z-score is between -0.1095 and 0.1095
Pr( -0.1095 ≤ z ≤ 0.1095)
According to the z table, the probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753
