Answer:
It's 4x - 8 + 4y
Step-by-step explanation:
4(x-2+y)
4 (x) = 4x
4 (2) = 8
4 (y) = 4y
4x - 8 + 4y
That is false.
<span>To get the reciprocal of a number, we divide 1 by the number.
</span><span>We can think of a whole number as being "number/1", so the reciprocal is just like "flipping it over"
</span>For Fractions, Flip the Whole Fraction Over
Example: the reciprocal of <span>3/4</span> is <span>4/<span>3.</span></span>
Answer:
Mean $1060
Standard error $34.69
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation, which is also called standard error, .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Population:
Mean $1,060 and standard deviation $190.
Sampling distriution of samples of size 30:
Mean $1060
Standard deviation
