ANSWER
The correct answer is C
EXPLANATION
We want to find the quotient:
We multiply by the reciprocal of the second fraction:
We cancel out the common factors to obtain:
We multiply to get
This simplifies to :
The correct answer is C
A stuntman jumping off a 20-m-high building is modeled by the equation h = 20 – 5t2, where t is the time in seconds. A high-speed camera is ready to film him between 15 m and 10 m above the ground. For which interval of time should the camera film him?
Answer:
Step-by-step explanation:
Given:
A stuntman jumping off a 20-m-high building is modeled by the equation
-----------(1)
A high-speed camera is ready to making film between 15 m and 10 m above the ground
when the stuntman is 15m above the ground.
height
Put height value in equation 1
We know that the time is always positive, therefore
when the stuntman is 10m above the ground.
height
Put height value in equation 1
Therefore ,time interval of camera film him is

Answer:
The value is not close to 0.3 because of sampling variability.
Step-by-step explanation:
The group of answer choices are not given which are as follows:
- All of the above
- Because the sample size is too small
- Because of sampling variability
- Because of nonresponse bias
From this the correct option is option C which is Because of Sampling Variability.
This is true because the two populations are of different values and thus the sample is not dependent on any one of the two possibilities. When a sample of 4 is considered from first and 400 from the second the overall probability will be far from the value of 0.3. So the
