Can someone solve this? No guessing! Explain very well! Make sure the answer is right!
DedPeter [7]
In the survey, 9 said they prefer the coffee shop next door out of 45 people total surveyed. This forms the fraction 9/45 = 1/5 which converts to 0.2 when you use a calculator or long division. In other words, 1/5 = 0.2

You'll then multiply the result of 0.2 by the total number of employees (250) to get...

0.2*250 = 50

So based on the results of the survey, we expect about 50 employees to say they prefer the coffee shop next door.

Answer: Choice B) 50

Find the equation of line (use exact numbers)​
maw [93]

Answer:

y=3x+3

Step-by-step explanation:

Use the slope-intercept form:

y=mx+b

m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( \frac{rise}{run} ).

If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:

y=mx+3

Now find the slope. Use the slope formula:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}

You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:

(0_{x1},3_{y1})\\(1_{x2},6_{y2})\\\\\frac{6-3}{1-0}=\frac{3}{1}=3

The slope is 3. Insert this value:

y=3x+3

The length of ZX is 2 units. What is the perimeter of triangle XYZ?
dezoksy [38]

Keywords

triangle,perimeter,distance, length, side, points

we know that

The <u>perimeter</u> of a<u> triangle</u> is the sum of the three <u>length</u> <u>side</u>

To find the<u> length</u> <u>side</u> calculate the <u>distance</u> between two <u>points</u>

The formula to calculate the <u>distance</u> between to <u>points</u> is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}


Step 1

Find the <u>distance</u> ZY

Z(1,0)\\Y(3,1)  

substitute the values


d=\sqrt{(1-0)^{2}+(3-1)^{2}}


dZY=\sqrt{5}\ units


Step 2

Find the <u>distance</u> XY

X(-1,4)\\Y(3,1)  

substitute the values


d=\sqrt{(1-4)^{2}+(3+1)^{2}}


dXY=\sqrt{25}=5\ units  

Step 3

Find the <u>perimeter</u> of the <u>triangle</u>

P=ZX+ZY+XY

we have

dZX=2\sqrt{5}\ units


dZY=\sqrt{5}\ units


dXY=5\ units  

Substitute

P=(2\sqrt{5}+\sqrt{5}+5)\ units

therefore

the answer is

P=(3\sqrt{5}+5)\ units
