Answer:
It would be a point at (-4,-7)
Step-by-step explanation:
Yes, the sampling distribution is normally distributed because the population is normally distributed.
A sampling distribution is a chance distribution of a statistic obtained from a larger variety of samples drawn from a specific populace. The sampling distribution of a given population is the distribution of frequencies of a variety of various outcomes that would probable occur for a statistic of a populace.
A sampling distribution is a probability distribution of a statistic this is obtained via drawing a huge variety of samples from a particular populace. Researchers use sampling distributions so that you can simplify the technique of statistical inference.
Solution :
mean = μ40
standard deviation σ σ= 3
n = 10
μx = 40
σ x = σ√n = 3/√10 = 0.9487
μ x = 4σ\x = 0.9487
σx = 0.9487
Yes, the sampling distribution is normally distributed because the population is normally distributed.

The difference in the dogs weight from 2 years ago is -0.83
Answer:
Step-by-step explanation:
The triangle ABC(on the right hand side) is mirrored about the y-axis and translated one unit in the direction of the negative y-axis and the result the triangle DFE(on the left hand side)
Note that the same result can be obtained by translating then mirroring.
The Size(Area) is actually the same.
So basically If its coordinates was ( x , y )
it's now ( -x , y-1 )
(- minus) Due to Mirroring
(-1) duo to Translating in the negative direction
This shows that if s is doubled and h tripled, then V multiplied by 12
<h3>Volume of a cuboid</h3>
Given the formula below expressed as:
V = s²h
If s is doubled and h tripled, the new volume will ne:
V1 = (2s)² * 3h
V2 = 4s² * 3h
V2 = 12s²h
V2 = 12V
This shows that if s is doubled and h tripled, then V multiplied by 12
