Fynjy0 [20]

Answer: (23.3,\ 29.7)

Step-by-step explanation:

The confidence interval for population mean is given by :-

\overline{x}\pm ME., where \overline{x} is the sample mean and ME is the margin of error .

Given : The sample mean : \overline{x}=26.5

Margin of error : ME=3.2

Then , the range of values​ (confidence interval) likely to contain the true value of the population parameter will be :-

26.5\pm 3.2=(26.5-3.2,\ 26.5+3.2)=(23.3,\ 29.7)

Hence, the range of values​ likely to contain the true value of the population parameter =  (23.3,\ 29.7)

The mapping diagram shows a function S(x).<br><br> Which mapping diagram shows the inverse of S(x)?
Nutka1998 [239]
<h3>Answer: Choice A</h3>

Explanation:

Notice how the input 5 leads to the output 3 when we look at the S(x) function. The inverse will undo this. So that must mean the answer is choice A where we have the input 3 lead to the output 5. In short, the inputs and outputs swap places. This means the domain and ranges swap.

What is the slope of the line through (6, 9) and (7, 1)<br>a. -1/8<br>b. 8<br>c. -8<br>d. 1/8​
eduard

Answer:

Slope is  -8

Step-by-step explanation:

First and foremost, welcome to Brainly!

I'll begin with the basics of slope, just to help you get the gist of this crucial concept -

Slope can be rewritten as rise/run, although written formally as :

m = \frac{y_{2}-y_{1}  }{x_2-x_1}

when we are given two coordinates (x,y) on the line.

One important thing to note is that slope belongs to a general equation,

y = mx+b

where b represents the y intercept and m is slope.

We're given two coordinates in your question: (6,9) and (7,1):

m = \frac{1-9}{7-6} = \frac{-8}{1} =-8

m = -8 is the final answer.

I hope this helps! By the way, slope is a concept that will follow you to calculus and physics, so I urge you to practice!
