6.25 because 2.5+2.5= 5 and then half of 2.5 is 1.25 so 6.25
Answer:
Step-by-step explanation:
→ First look at the first term of each expression and see if they can be simplified, and they can
→ Now look at the a terms, since a larger one is at the top, you subtract
→ Now simplify the b and c terms
Answer:
D
Step-by-step explanation:
(the line is a / shape, so the slope is positive)
(the line crosses the y axis at (0,-2))
(using the above information, we can conclude that the equation is y=2x-2)
or
slope = m = rise/run = 2/1 = 2
y=mx+b
y=2x+b
Choose any point on the line) (1,0)
0=2(1)+b
b=-2
y=2x-2

Step-by-step explanation:
There were no graphs listed in your question. So...
Convert the inequality to interval notation.
The sampling distribution is illustrated below.
<h3>How to illustrate the sampling?</h3>
Based on the information given, the population is illustrated as 1, 4, 7. The sample without replacement will be:
<u>Sample Mean</u>
1 and 4. 2.5
1 and 7. 4
4 and 7. 5.5
The population mean will be:
= (1 + 4 + 7)/3
= 4
The sample mean is an unbiased estimator of the population mean.
The sampling with replacement illustrates that the mean will be:
= 36/9 = 4
Also, when n = 3, the number of samples will be:
= 3³ = 27
