Answer:

58

Step-by-step explanation:

The center line in a box plot represents the median

This is the same as saying 27 cubic inches

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

Explanation:

We get the volume of a cube by using the formula

V = s^3

where the cubed exponent is directly tied together with the idea of volume being in cubic units. In this case, s = 3 which leads to

V = s^3

V = 3^3

V = 3*3*3

V = 27 cubic inches

As another example, let's say s = 4. That means

V = s^3

V = 4^3

V = 4*4*4

V = 64

We multiply the side length by itself having three copies total. This formula only applies to cubes. A more generalized formula for rectangular blocks is V = L*W*H where L,W,H are the length width and height in that order. This generalized formula allows for side lengths to be different, but if L = W = H, then it makes more sense to go with the first formula instead.

Answer: C 1.6 K cents

Step-by-step explanation:

Answer:

slope = 3/7

Step-by-step explanation:

To find slope we need two coordinates from the line.

Let it be (-7, 0) and (3, 0)

[tex]slope, m = \frac{y_2-y_1}{x_2-x_1}= \frac{3-0}{0--7} = \frac{3}{7}[/tex]

Hi there!

[tex]\large\boxed{\text{False.}}[/tex]

f(x) = 2(1/5)ˣ

Recall the form of an exponential function:

f(x) = a(b)ˣ where:

a = initial value

b = rate of decay/growth

If b > 1, the function is undergoing exponential growth. If b < 1, then the function is undergoing exponential decay.

1/5 < 1, so the function is undergoing exponential decay, not growth.

Answer:

-0.5

Step-by-step explanation:

Slope (m) = [tex]\frac{1.3 - 3.8}{0.18 + 4.82}[/tex]

or, m = -2.5/ 5

or, m = -1/2 = -0.5

∴Slope is -0.5

Answer:

solved graphically,

it's just the point where the two lines intersect

Answer:

∠ A ≈ 44.42°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos A = [tex]\frac{adjacent}{hypotenuse}[/tex]  = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{5}{7}[/tex] , then

∠ A = [tex]cos^{-1}[/tex] ([tex]\frac{5}{7}[/tex] ) ≈ 44.42° ( to the nearest hundredth )

Method 1

Given:

374F in base 16

To convert to octal;

(i) convert each digit in the number to binary

3 = 0011

7 = 0111

4 = 0100

F = 1111

(ii) join the bits together starting from the first i.e

374F = 0011 0111 0100 1111

(iii) starting from the right to left, group the bits together, each group having 3 bits

374F = 0 011 011 101 001 111

(iv) the group with number of bits less than 3 should be padded with zero.

374F = 000 011 011 101 001 111

(v) convert each of the groups in (iv) above to decimal as follows:

000 = 0

011 = 3

011 = 3

101 = 5

001 = 1

111 = 7

(vi) combine the result above to get;

033517

The first zero can be removed

33517

Therefore, the number in octal is 33517₈

Method 2

Given:

374F in base 16

To convert to octal;

i) convert the number to decimal as follows;

a. Multiply each digit by 16 raised to the power of one less than their position starting from the leftmost digit.

=> 3 is at position 4, so we have

3 x 16⁴ ⁻ ¹ = 3 x 16³

=> 7 is at position 3, so we have

7 x 16³ ⁻ ¹ = 7 x 16²

=> 4 is at position 2, so we have

4 x 16² ⁻ ¹ = 4 x 16¹

=> F is at position 1, so we have

F x 16¹ ⁻ ¹ = F x 16⁰

b. Add each of the terms found in (a) together.

(3 x 16³) + (7 x 16²) + (4 x 16¹) + (F x 16⁰)

c. Remember that F = 15 in decimal. Therefore, substitute F = 15 into the result in (b)

(3 x 16³) + (7 x 16²) + (4 x 16¹) + (15 x 16⁰)

d. Solve the result in (c)

(3 x 4096) + (7 x 256) + (4 x 16) + (15 x 1)

12288 + 1792 +64 + 15

14159

Therefore,

374F in decimal is 14159

(b) Now convert the decimal to octal by dividing by 8 and noting the remainder.

8 | 14159

8 | 1769 r 7

8 | 221 r 1

8 | 27 r 5

8 | 3 r 3

  | 0 r 3

Taking the remainders from bottom up gives

33517₈

Therefore, the number in octal is 33517₈

2x-3y<7

Step-by-step explanation:

Answer:

x=24   2x=48

Step-by-step explanation:

We first do 112-64 which will give us 2x.

So, we know 48=2x.

divide both sides by two and we get:

x=24

Answer:

B

Step-by-step explanation:

2x and 48 are opposite from each other, making them equal

if you put them into an equation to solve for x, you get:

2x=48

/2    /2

x=24

now that you have x, you can plug it back into the original equation to get: 48

Answer:

9.8

Step-by-step explanation:

Use the distance formula to determine the distance between the two points.

[tex]d = \sqrt{(x_{2} -x_{1})^{2} + (y_{2} - x_{1})^{2} }[/tex]

d = distance

[tex](x_{1}, y_{1})[/tex] = coordinates of the first point

[tex](x_{2}, y_{2})[/tex] = coordinates of the second point

Given:

Consider the below figure attached with this question.

To find:

The conclusion that can be determined from the dot plot.

Solution:

The number of dots in the dot plot is 15. So, the number of observations is 15 and option D is correct.

The data set represented by the dot plot is:

2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6

Number of observations is 15, which is an odd number. So, the median of the data set is:

[tex]Median=\dfrac{15+1}{2}\text{th term}[/tex]

[tex]Median=\dfrac{16}{2}\text{th term}[/tex]

[tex]Median=8\text{th term}[/tex]

[tex]Median=4[/tex]

The median of the data set is 4. So, option A is incorrect.

Mean of the data set is:

[tex]Mean=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}[/tex]

[tex]Mean=\dfrac{2+2+3+3+3+4+4+4+4+4+5+5+5+6+6}{15}[/tex]

[tex]Mean=\dfrac{60}{15}[/tex]

[tex]Mean=4[/tex]

The mean of the data set is 4. So, option B is incorrect.

The range of the data set is:

[tex]Range = Maximum - Minimum[/tex]

[tex]Range = 6-2[/tex]

[tex]Range = 4[/tex]

The range of the data set is 4. So, option C is incorrect.

Therefore, the correct option is D.

Answer:15

Step-by-step explanation:

Answer:

x = - 1

Step-by-step explanation:

Given

4x = x^2 - 5               Transfer 4x to the right side.

Solution

x^2 - 4x - 5 = 0          Factor

(x - 5)(x + 1)

You want the negative solution. That means that the middle sign must be plus.

x + 1 = 0                   Subtract 10 from both sides

x = - 1                       Ten on the left disappears by the subtraction process.

Is that correct?

4x = x^2 - 5

x = - 10

4*(-1) = (-1)^2 - 5

-4  = ? 1 - 5

-4 = - 4

and it does work.

36

Step-by-step explanation:

5x is 15

x is 3

12 times 3 is 36

Answer:

5x + 2 = 17

5x = 17 - 2

5x = 15

x = 3

Therfore, 12x = 12 (3) = 36

PR / Sin(Q) = QR / Sin(P)

53 / Sin(90) = 45 / Sin(P)

53 / 1 = 45 / Sin(P)

Sin(P) = 45 / 53

Sin(P) = 0.8490566038

P = 58.11 degrees

Answer:

58.11°

Step-by-step explanation:

tan P = 45/28 = 1.607

< P = tan`¹ 1.607 = 58.11°

Answer:

Answer:

A = 388.58 cm^2

Step-by-step explanation:

For a cone whose base has a radius R, and a hypotenuse S, the area is:

A = pi*R^2 + pi*R*S

Where pi = 3.14

In this case, we can see that the diameter is: 15cm

Then the radius, half of the diameter, is:

R = 15cm/2 = 7.5cm

The hypotenuse is 9cm, then S = 9cm

A = 3.14*(7.5cm)^2 + 3.14*(9cm)*(7.5cm) = 388.575 cm^2

Rounding to two decimal places, we need to look at the third one, which is a five, so we need to round up:

A = 388.58 cm^2
