Answer:
it might be 18 ❤
Step-by-step explanation:
I'm pretty sure it is 18 let me know
Answer:
Step-by-step explanation:
from the question,
the mean 14
the standard deviation is 3
and sample size is 10.
since the n which is the sample size is 10, then the distribution is mound shaped.
why?
this is due to the fact that the random variable from which we took the sample is mound shaped.
The sampling distribution of the mean is normally distributed although the question says the random variable is not normally distributed. so the shape is bell shaped and normally distributed.
the standard deviation of the mean is
3/√10
= 0.948
Answer:
(1)
Step-by-step explanation:
We will try:
(1) y = 
x => 2 = 2 (seems legit)
(2) y = 4x => 2 = 32 (nope)
(3) y = x - 6 => 2 = 2 (yes but actually no because it is proportional relationship)
(4) y = 
x - 2 => 2 = 2 (like the above)
Step-by-step explanation:
An=-6+(20-1)×2
=-6+19(2)
=-6+38
=32
The graph has no scale, so we can only make conclusions based on:
1. slope is negative (true), zero, or positive
slope is coefficient of x when equation is in standard form
2. y-intercept is negative, zero, or positive (true)
y-intercept is value of y when x=0
3. x-intercept is negative, zero, or positive (true).
x-intercept is value of x when y=0
Now let's look at the given answer choices:
A. 2x-y=7 => y=2x-7 => slope=2 >0 (false); => FALSE
B. 3x+2y=6 => y=-1.5x+6 => slope<0 (true); y-intercept>0 (true); x-intercept=6/3=2 >0 (true) => TRUE
C. y=5 => slope=0 (false) => FALSE
D. y=-4x+2 => slope=-4 <0 (true); y-intercept=2>0 (true); x-intercept=+1/2>0 (true) => TRUE
