What is the mean of the data set?

2 answers:

4 0

You find the mean by adding each value then dividing the sum by the number of values there were so in this case you'd say 301 + 222 + 287 + 310 + 346 which is 1466 then divide by 5 because there are 5 values and your answer is 293.2!

I hope this helps

You Add All The Numbers Together

<span>301+222+287+310+346= 1,466

Then You Divided It By How Many Sets Of Number You Have Which Would Be 5

Finally Your Answer Is 293.2

Which is the best approximation for the value 140

zzz [600]

140 is a composite number. Factor pairs: 140 = 1 x 140, 2 x 70, 4 x 35, 5 x 28, 7 x 20, 10 x 14. Factors of 140: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140. Prime factorization: 140 = 2 x 2 x 5 x 7, which can also be written 140 = 2² x 5 x 7

Jocelyn just accepted a job at a new company where she will make an annual salary of $70000. Jocelyn was told that for each year

Oksanka [162]

Answer:

$80,500

55,500 + 1,500t

Step-by-step explanation:

The question is an arithmetic progression series

Where,

a= first term

d= common difference

n= number of terms

a = $70,000

d= $1,500

n= 8 years

8th term = a + (n-1) d

= 70,000 + (8-1)1500

= 70,000 + 7(1500)

= 70,000 + 10,500

= $80,500

Jocelyn salary after 8 years is $80,500

Solve for when n = t

t th term = a + (n-1)d

= 70,000 + (t - 1)1500

= 70,000 + 1,500t - 1,500

= 55,500 + 1,500t

t th term = 55,500 + 1,500t

A window is being replaced with tinted glass. The plan at the right shows the design of the window. Each unit length represents

PolarNik [594]

The answer is $911.68.

After a little research on the internet, I found the design of the window.
First, you need to find the area of the window which is a composite figure made up of a rectangle and a circle. So, the total area (A) is the sum of the area of the rectangle (A1) and the area of the circle (A2).

Area of the rectangle with length l and width w is:
A = l * w
According to the image, l = 5 ft and w = 4 ft.
A1 = 5 * 4 = 20 ft²

Area of the circle with radius r is:
A = r²π
According to the image, r = 2 ft.
A2 = 2² * 3.14 = 12.56 ft²

The area of the window is:
A = A1 + A = 20 ft² + 12.56 ft² = 32.56 ft²

<span>The glass costs $28 per square foot, so to replace the glass will cost:
</span>32.56 ft² * $28/ft² = $911.68

Please help me with this.A rectangular field is

Karolina [17]

First, let's get the perimeter of the rectangle:
$P=2W+2L$
$P=130m+210m$
$P=340m$
Then, let's get the area of the bigger one:
$A=WL$
$A=65m*105m$
$A=6825m^2$

Then let's try using a rectangle with a smaller ratio:
$P=100m+240m$
$P=340m$
Then:
$A=50m*120m$
$A=6000m^2$

If you used a square:
$P=170+170$
$P=340$
$A=WL$
$A=85^2$
$A=7225$

There you have it. A rectangle with a smaller area with the same perimeter.
What does it show? The smaller the difference you get from width and length, the larger the area is.
