Answer:

25.13 or 8 × pi

Step-by-step explanation:

diameter × pi = circumference

Answer:

8π

Step-by-step explanation:

formula for circumference of a circle=

C=2πr, r= radius

the radius is the diameter divided by 2

radius= 8/2=4

plug into formula

C=2π4

multiply 2 and 4

C=8π

Answer:

Nominal variables.

Step-by-step explanation:

In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.

Basically, random variables are classified into two (2) main categories and these are;

1. Discrete variable: a discrete variable is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.

2. Continuous variable: a continuous variable is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous random variable.

Hence, the other name for continuous variables is nominal variables because they are numerical in nature.

Answer:

m = 3/4

Step-by-step explanation:

We have the points (-2,2) and (2,5). We can use those to calculate the slope:

m = 5 - 2 / 2 - (-2)

m = 5 - 2 / 2 + 2

m = 3/4

Answer:

answer 3, hope this is right

Step-by-step explanation:

Answer:

The scale factor is 1/60

we know that

The scale factor is equal to the ratio between the side length of the scale drawing to the corresponding side length in the actual

so

2/120 = 1/60

The scale factor is 60 and the dimension of the actual skate park that corresponds to 4 ft on the scaled drawing is 240 feet.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Given that a skate park has side lengths of 2 feet, 4 feet, 1.5 feet, and 3 feet.

The 2 ft side length of the scale drawing corresponds to a side length of 120 feet for the actual skate park.

We need to find the scale factor

scale factor = actual length / corresponding length in the scale drawing

scale factor = 120 ft / 2 ft

scale factor = 60

Therefore, the scale factor is 60.

The dimension of the actual skate park that corresponds to 4 ft on the scaled drawing, we can multiply the length in the scale drawing by the scale factor:

actual length = length in the scale drawing × scale factor

actual length = 4 ft × 60

actual length = 240 ft

Hence,  the scale factor is 60 and the dimension of the actual skate park that corresponds to 4 ft on the scaled drawing is 240 feet.

Answer:

191 ft

Step-by-step explanation:

Mathematically, the area of a square is the square of the length of its side

so if the side is l, the area will be l^2

we need the length before we get the perimeter

Thus;

l^2 = 210.25

l = √210.25

l = 14.5 m

We now need to get the perimeter of the drive way

The perimeter of the driveway will be 4 * l

= 4 * 14.5 = 58 m

we now convert this to ft

From the question;

3.3 ft = 1 m

x ft = 58 m

x = 58 * 3.3

x = 191.4 ft

To the nearest foot, this is 191 ft

D

Step-by-step explanation:

Answer: choice D) [tex](y-x)(y-z) \le 0[/tex]

=====================================================

Explanation:

Unfortunately, we don't have enough info to determine what x,y, and z are.

However, we do know that x < y < z is the case. Though to be more technical, x = y or y = z could be possible, but for now we'll ignore these cases.

So we'll focus on x < y < z.

This is true because 25% of the values are below x and 50% of the values are below y. So naturally x is smaller than y. Also, 75% of the values are smaller than z, so z is the largest of the three values.

Since x < y, this makes 0 < y-x when you subtract x from both sides. This is the same as saying y-x > 0. So y-x is positive.

On the other hand, because y < z, this leads to y-z < 0. So y-z is negative.

We have

therefore, (y-x)(y-z) = (positive)*(negative) = negative

Overall,

(y-x)(y-z) < 0

So far, we can see that we have strict inequality. However, it is possible to have x = y or y = z be possible. Consider a set like {5,5,5,7,9}. You should find that Q1 = 5 and Q2 = median = 5 also. This example is one of infinitely many where x = y. Due to something like this, we must update (y-x)(y-z) < 0 into [tex](y-x)(y-z) \le 0[/tex]

3.)

There are 4 oranges and 6 apples so the fraction would be 4/6 which we can reduce to 2/3.

a.) As we stated beforehand, the fraction was 2/3. That means for every 2 oranges, there are 3 apples.

b.) We did this already. 4/6 was reduced to 2/3.

Answer:

(-8,-8) or x = -8 & y = -8

Step-by-step explanation:

add both equations to get:

-3x=24

x = -8

now substitue x = -8 into the fisrt equation:

-7(-8) + 4y = 24

56 + 4y = 24

4y = 24 - 56

4y = -32

y = -8

now the answer would be in (x,y) form:

Answer: 2/3yards

Step-by-step explanation:

From the question, we are informed that Jill is making a long cape and that she needs 7 1/3yards of blue fabric for the outside of the cape and that she needs 6 2/3yards of purple fabric for the lining of the cap.

To calculate the yards of blue fabric that'll be needed more than purple fabric,, we subtract 6 2/3 from 7 1/3. This will be:

= 7 1/3 - 6 2/3

= 2/3

She needs 2/3yards of blue fabric more.

Answer:64=36

Step-by-step explanation:

His total monthly cash inflow is $2073.6 which is the correct answer would be option (D).

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

We have been given that Tyrone’s hourly wage is $18

And he spends about $1,800 on his monthly expenses

Since Tyrone works 40 hours per week

So Monthly hours worked would be: 40 × 4 = 160

To determine the total wage

We have multiplied the hours worked by the wage rate  

So total wage = hours worked × wage rate  

Total Wage = 160 × 18 = 2880

Tyrone's net salary is 72% of his total income, as determined by the formula below:

Tyrone's net salary = 72% of the total Wage

Tyrone's net salary = 0.72× 2880

Tyrone's net salary = 2073.6

Therefore, His total monthly cash inflow is $2073.6 which is the correct answer would be an option (D).
