Answer:
The usual way to draw a 3-D grid can be seen below.
The positive z-axis points upwards
The positive y-axis points to the right
The positive x-axis points towards you, or to the front.
And the notation for a point in 3-D is (x, y, z)
In this case, our point is (-3, -2, 3)
Then the location of the point can be described as:
So the x-value is -3, which means that the point is 3 units behind the origin.
The y-value is -2, which means that the point is 2 units at the left of the origin
The z-value is 3, which means that the point is 3 units above the origin.
Answer:
(7/3, -1). 7/3 is the missing coordinate.
Step-by-step explanation:
Plug in -1 for y. You get:
3x+4=11.
Subtract 4 on each side:
3x=7
Divide each side by 3:
x=7/3

Answer:
E. Approximately normal with standard deviation less than 0.7 sibling
Step-by-step explanation:
To solve this question, we use the Central Limit theorem.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
In this problem, we have that:
Skewed right distribution, with 
Sampling distribution of the sample mean for samples of size 100
By the Central Limit Theorem, they will be approximately normal, with mean 
, and standard deviation 
So the correct answer is:
E. Approximately normal with standard deviation less than 0.7 sibling
