Answer:
2
Step-by-step explanation:
A coefficient is the number before the variable.
26 ( 2+5+8=15 ) (41-15=26)
Answer:
10.0
Step-by-step explanation:
see attached for reference.
given two points in the x-y axis (x₁, y₁) and (x₂, y₂)
the distance bettween them is given by
Distance, D = √ ( (x₂-x₁)² + (y₂-y₁)² )
In our case we are given points (9,10) and (-1,9)
substituting these into the formula , we get:
D = √ ( (9-10)² + (-1-9)² )
= √ ( (-1)² + (-10)² )
= √ ( 1 + 100 )
=√101
= 10.04988
= 10.0 (rounded to nearest tenth)
Answer:
144 is the l.c.m of 16 and 18
explanation:
<u>multiples</u>:
16 - 16, 32, 48, 64, 80, 96, 112, 128, 144
18 - 18, 36, 54, 72, 90, 108, 126, 144
Therefore, 144 is the l.c.m of 16 and 18 which is divisible by both numbers.
Answer:
C.The mean of the sampling distribution is always
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size, of at least 30, can be approximated to a normal distribution with mean
and standard deviation
.
So
A is wrong, because it is ![\frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
B is wrong, you need a sample size of at least 30.
So the correct answer is:
C.The mean of the sampling distribution is always
