The distance a circle's circumference extends from one end to the other is known as the diameter.

The circumference of a circle is the distance of its outer length.

According to the formula, c = πd, c is the circumference of the circle and d is the diameter of the circle.

Value of π is 3.14

When c = 25.12 inches, the value of d will be

d = c/π

d = 25.12/3.14

The polynomial that represents the volume of the rectangular box is 3x² - x - 24 = 0

The dimension of the rectangular box are 9 inches, 8 inches and 3 inches.

The volume of the rectangular box can be expressed as follows:

volume of the rectangular box = l w h

where

Therefore,

w = x inches

l = 3x

h = 3x - 1

volume of the rectangular box = 72x

Therefore, the polynomial that represents the volume of the rectangular box is as follows:

72x = 3x × x × (3x - 1)

72x = 3x²(3x - 1)

72x = 9x³ - 3x²

9x³ - 3x² - 72x = 0

3x(3x²- x - 24) = 0

3x² - x - 24 = 0

Therefore,

x = 3 or - 8 / 3

we can only use positive values.

Hence, the dimension of the rectangular box is as follows:

w = 3 inches

l = 3(3) = 9 inches

Answer:

m= 3

Step-by-step explanation:

In the slope-intercept form (y= mx +c), the coefficient of x (when the coefficient of y is 1) is the slope.

y= x +5

Slope of line= 1

Parallel lines have the same slope, hence the slope of 3y -mx +3= 0 is also equal to 1.

Let's rewrite the equation into slope-intercept form.

Keep the y term on the left-hand side, bring the others to the right.

3y= mx -3

Divide both sides by 3:

[tex]y = \frac{m}{3} x - 1[/tex]

Given that the slope is 1,

[tex] \frac{m}{3} = 1[/tex]

Multiply both sides by 3:

m= 1(3)

m= 3

kx² - 4x + 1 = 0

Now, for a quadratic equation to have 2 equal roots, it means that;

Answer:

B) To make a right triangle in the center, the area of the smaller two square must add to equal the area of the largest square

Step-by-step explanation:

1) add the area of the two smaller squares together

f^2= 9

g^2 = 16

9+16=25

2) compare the sum of the two squares to the larger square (the hypotonus)

h^2= 25 so, f^2 + g^2 = h^2

3) The area of the smaller squares is equal to the area of the larger square, therefore b is the correct answer.

The experimental probability of an odd number other than 9 being generated is 0.38.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

According to the probability formula, the probability of an event occurring, or P(E), is equal to the proportion of positive outcomes to all outcomes. P(E) is defined mathematically as favorable outcomes divided by total outcomes.

Given Data

A random number generator is used to create a list of 150 single-digit numbers. Of those 150 numbers, 72 are odd and 78 are even. The number 9 was generated 15 times.

Total numbers generated = 150

Odd numbers = 72

Even numbers = 78

Generation of number 9 = 15

Number of odd numbers except 9 itself

= 72 -15

= 57

Probability = [tex]\frac{Odd numbers except 9 itself}{total munbers}[/tex]

Probability = [tex]\frac{57}{150}[/tex]

Probability = 0.38

The experimental probability of an odd number other than 9 being generated is 0.38.

The number of terms of the second arithmetic progression is 46.

The two arithmetic progression have the same first and last terms.

The first arithmetic progression has 21 terms with a common difference of 9.

The second arithmetic progression have common difference of 4.

Therefore,

using the first arithmetic progression,

a + (n - 1)d = nth term

a + 20(9) = last term

last term = a + 180

using the second arithmetic progression,

a + (n - 1)d = nth term

They have the same last and first term,

Hence,

a + 180 = a + (n - 1)4

a + 180 = a + 4n - 4

180 + 4 = 4n

184 = 4n

n = 184 / 4

The absolute value equation representing all numbers x whose distance from 8 is 6 units will be x = {2, 14).

Based on the information given, it should be noted that the distance of x, positive or negative from 8 can be expressed as |x - 8|.

Since the distance is equal to 6, our equation will be:

|x - 8| = 6

x = 8 + 6 = 14

or

- |x - 8| = 6

-x + 8 = 6

-x = 6 - 8

Answer: The arrow is pointing to 76.5.

Step-by-step explanation: It's pointing to 76.5 because there are 10 spaces between 75 and 80 so in that case, each line is .5, and since it's on the third line that means it is 1.5 more than 75 so 76.5.

Answer:

C) The arrow points to 76.5.

Step-by-step explanation:

The number line is divided into 10 parts equally.

We can find out the distance between each point by taking the difference between the largest and smallest number on the number line and dividing the difference by 10.

80 - 75 = 5

5/10 = .5

So, the distance between each number/mark on the line is .5

Now, we can label each point by adding .5 to each mark as we go. Then, we'd get this.

*see attachment below

Since the number line constructed here has all the values, we can now tell which value the arrow is pointing to.

The answer is therefore 76.5.

This is a Metric conversion problem. Note that it will take 38.4 minutes to create a 2-foot by 4-foot pattern drive. See the explanation below.

There are several ways to do this. Let's use the area of the times and that of the pattern drive.

Note that the area of the 3inch by 5-inch tile =

Area of a rectangle

L x B =

3 x 5

= 15inches

Applying the same rule to the pattern drive, we have
2 x 4

= 8 foot

Note that 1 foot = 12 inches

For convenience, thus, we convert the area of the pattern drives into inches. This gives us:
8 x 12

= 96 inches

To get how many minutes it will take to create a 2 by 4-foot pattern drive, we have

Recall that it takes 6 minutes to lay a 3x5 which is 12 inches in area.
Hence,

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

Parallel lines have the same gradient so equation of line is y = -3x + c.

Substitute (1,7) into the equation to find c.

7 = -3(1) + c

c = 10

Hence equation of line is y = -3x + 10

You must explicitly state that the null hypothesis is demonstrated to be true in cases where there is insufficient evidence to disprove it.

A statistical hypothesis known as a null hypothesis asserts that no statistical significance can be found in a collection of provided observations. Using sample data, hypothesis testing is performed to judge a theory's veracity. It is sometimes referred to as just "the null," and its symbol is H₀

Even though we are unable to rule out the null hypothesis, this does not always imply that it is accurate. The reason for this is that a hypothesis test cannot tell which hypothesis is true or even which is more likely. It just evaluates whether there is sufficient evidence to disprove the null hypothesis.
