A department store uses a markup of 40%. Calculate the selling price of a shirt that cost the retailer $25.

A marketing research company is estimating the average total compensation of party clowns. Data were randomly collected from 48

ExtremeBDS [4]

Answer:

"90% confidence" means there is a probabilty of 90% that the population mean (average compensation for the population of party clowns) lies within the confidence interval.

Step-by-step explanation:

The confidence interval is a range of values in which, according to the level of confidence that is calculated, is likely to include a parameter of the population. In this case, this parameter is the population mean compensation of party clowns.

The level of confidence is 90%, so there is 90% of confidence (or probability) that the population mean compensation for party clowns lie within $9394 and $9926.

None of the options below is correct.

The equation of a line is given as y=0.5x+1

QA). What is the slope of the line in the graph

Ans.

The slope is given as $s=\frac{Y2-Y1}{X2-X1}$

In the graph, the line passing through points (0,5)(-5,0)

The slope of a line:

$s=\frac{Y2-Y1}{X2-X1}$

$s=\frac{0-5}{(-5)-0}$

$s=1$

The slope of the line in the graph is 1

QB). What is the slope of the line in the table

Ans.

The slope is given as $s=\frac{Y2-Y1}{X2-X1}$

In the table, the line passing through points (0,3)(1,6)

The slope of a line:

$s=\frac{Y2-Y1}{X2-X1}$

$s=\frac{6-3}{(1-0}$

$s=3$

The slope of the line in the table is 3

QC). What is the slope of the line in the equation

Ans.

The equation of a line is given as y=mx+c

The equation of a line is y=0.5x+1

Where m= slope

On comparing both the equation we get,

m=0.5

The slope of line in the equation is 0.5

QD). Which has the greatest rate of change

Ans.

The slope of the line in the graph is 1

The slope of the line in the table is 3

The slope of the line in the equation is 0.5

There, Rate of change is also called as the slope and it is greatest in case of the table.

Help anyone can help me do this question,I will mark brainlest.

FrozenT [24]

Answer:

3) 16π cm²

4) 240.625 cm²

Step-by-step explanation:

3. For this problem I'm going to use the formula Area = π × r²

To start off, I'm going to input our value of radius which is 4cm.

π × 4²

Finally, I'm going to square our value "4"

16π cm²

(I'm going to "leave my answer in terms of π" as the problem states but if you need the complete answer it would be about 50.24 cm²

4. For this problem I'm going to use the formula Area = π × (d/2)²

To begin, I will divide our diameter by 2 to find the radius.

17.5/2 = 8.75

Next, we are going to square our now, radius.

8.75² = 76.5625

Now, we have to multiply our squared radius by π (in this problem it states to use 22/7, so that's what we'll do :)

76.5625 × 22/7 = 240.625 cm²

So! This is our final answer!

Hope this Helps! :)
