Given:

A box-and-whisker plot of data set.

To find:

The percentage of the data values that are greater than 80.

Solution:

From the given box-and-whisker plot, it is clear that:

Minimum value = 8

First quartile = 60

Median = 68

Third quartile = 80

Maximum value = 92

We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.

Therefore, about 25% of the data values that are greater than 80.

Answer:

Take away 1 from either side so the equation becomes 63=3x then divide both sides by 3 so it becomes 21=x which is your answer (option A)

Answer:

The radius of the circle is 1 kilometer.

Step-by-step explanation:

The radius of the circle is the length from the very center of the circle to any other point in the circle. To find the radius, you only have to divide the diameter in half, so 2 ÷ 2 = 1. Hope this helped!! :]

Answer:

60 cm^2 (dark blue)

Step-by-step explanation:

Since a rhombus's diagonal bisect each other, the diagonal's full length is 10 and 12. From there the area is 10*12 / 2 which is 60

Answer: 45

Step-by-step explanation:

18 = 40% N

18 = 0.4 N

Divide both sides by 0.4

N = 45

There are 45 students want to be rescued.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Eighteen students decide they don't want to be rescued and want to continue to live in the jungle.

And, This represents 40% of the students.

Now,

Let the number of students want to be rescued = x

So, We can formulate;

⇒ 40% of x = 18

Solve for x as;

⇒ 40/100 × x = 18

⇒ 40x = 1,800

⇒ x = 1800/40

⇒ x = 45

Thus, The number of students want to be rescued = 45

Answer:

5 weeks

Step-by-step explanation:

First, solve for the total cost of the game console after tax and a coupon

Solve for tax:

$250 × 8.25%

Convert percentage into a decimal

250 × 0.0825

20.625

Round up to nearest hundredths place (because the unit is dollars)

20.63

Add this tax onto the original cost

250 + 20.63

270.63

Subtract the coupon from the total

270.63 - 10

260.63

Total cost is $260.63

Now let's find how much Kade needs to save so set up an equation

Variable x = number of weeks

45 + 45x = 260.63

Subtract 45 from both sides to isolate the variable

45x = 215.63

Divide both sides by 45

x = 4.791777...

Round up to nearest whole number (because units are weeks)

x = 5 weeks

Answer:

I’m pretty sure it’s right.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Line AB is parallel to line CD (k) so they have the same slope.

slope=m=(y2-y1)/(x2-x1)

m=(6-0)/(4-0)

m=6/4=1.5

y=mx+b, we know m=1.5 so

y=1.5x+b, and we know it passes through point (4,0) so we can solve for b

0=1.5(4)+b

0=6+b

b=-6 so line k is

y=1.5x-6

Answer:

1. it is 7 cm long

2. it is a chord

3. it is the diameter of the circle

Step-by-step explanation:

Here, we want to select three statements that are true about CB

From what we have, CB runs from one edge to the other, passing through the center of the circle

Also, as we can see, AD is a radius as it is the distance from the center of the circle to the circumference; CB is twice this as it is the diameter

The diameter is a chord that passes through the center of the circle and it is a radius

So let us select the correct statements;

1. it is 7 cm long

2. it is a chord

3. it is the diameter of the circle

Answer: what is R equal to?

Step-by-step explanation:

Answer:

It's been awhile since I've done this but wouldn't it be -2x

Step-by-step explanation:

This is because

tan(angle) = opposite/adjacent

For the reference angle 38, we have 10 as the opposite side and x as the adjacent side.

Therefore, tan(38) = opposite/adjacent = 10/x

Side note: if you solve for x, you should get roughly x = 12.799

Answer:

x = 75 hope this helped

Step-by-step explanation:

The true solution to the equation is,

⇒ x = 75

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]

Now, We can simply as;

⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]

⇒ 2 ln 2x - ln 10x = ln 30

⇒ ln (2x)² - ln 10x = ln 30

⇒ ln (2x)² / 10x = ln 30

⇒ 4x² / 10x = 30

⇒ 4x = 300

⇒ x = 75

Thus, The true solution to the equation is,

⇒ x = 75
