Answer:
The answer is below
Step-by-step explanation:
a) Given that the number of sample (n) = 300, therefore since n > 30, the distribution of the sample means is going to be normally distributed.
b) The mean of the distribution of sample means (also known as the Expected value of M) is equal to the population mean μ.
c) The standard deviation of the distribution of sample means is called the Standard Error of M, it is given by:
You have to distribute the 7 to x and 2 so :
7x+14=2x-1
Add one to both sides (inverse operations)
7x+14=2x-1
+1 +1
7x+15=2x
Cross Cancel by subtracting 7x from both sides
7x+15=2x
-7x -7x
15=-5x
Divide by -5
15/-5= -5/-5
X= -3
Values is 6 for lmso is a parellelle gram
Answer:
5 x k = 15 + 3 = 18
Step-by-step explanation:
k=3
Good evening ,
Answer:
<h2>(3,15)</h2>
Step-by-step explanation:
y=5x then
4x-y= -3 ⇌ 4x-5x= -3 ⇌ -x= -3 ⇌ x=3
and since y=5x then y=5×3=15.
