Answer 1

Answer:

the slope of y= -5x+7 is m= -5.

Answer 2

Answer:

A. The slope is -5, y-intercept is 7

Step-by-step explanation:

if y=mx+b, and m is the slope, then the slope is negative 5

if y=mx+b, and b is the y-intercept, then the y-intercept is 7

I toss a coin 20 times. comes up "Heads" 7 times. What is the 1 point
relative frequency of getting a "Head"?


Someone help please I have to finish this quickly—

Answers

Answer in fraction form =  7/20

Answer in decimal form = 0.35

Answer in percent form = 35%

These are three ways to say the same thing.

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

Explanation:

To get the relative frequency, you divide the number of times heads comes up out of the number of tosses total. Reduce the fraction as much as possible. In this case, 7 and 20 have no factors (other than 1) in common. So the fraction 7/20 cannot be reduced further.

The fraction 7/20 converts to the decimal form 0.35 after using a calculator or long division.

0.35 converts to 35% after moving the decimal over to the right two spots.

Explanation

Suppose the postal service charge is $10.30 per pound on a package shipped to England what is this rate in dollars per ounce

Answers

Answer: The required rate = 0.64 per pounce.

Step-by-step explanation:

We are given that,

Postal service charge = $10.30 per pound.

As we know,  1 pound = 16 ounces.

So,  Postal service charge = $10.30 per 16 ounces.

Postal service charge[tex]=\$\dfrac{10.30}{16}\ \text{ per ounce}[/tex]

[tex]\approx 0.64\text{ per ounce}[/tex]

Hence, the required rate = 0.64 per pounce.

Which sets of ordered pairs show equivalent ratios? (1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)

Answers

Given:

The different sets of ordered pairs in the options.

To find:

The sets of ordered pairs that show equivalent ratios

Solution:

The set of ordered pairs show equivalent ratios, if

[tex]\dfrac{y}{x}=k[/tex]

Where, k is a constant.

For option 1,

(1, 2), (2, 3), (4, 7)

[tex]\dfrac{2}{1}\neq \dfrac{3}{2}[/tex]

For option 2,

(2, 2), (4, 4), (6, 6)

[tex]\dfrac{2}{2}=\dfrac{4}{4}=\dfrac{6}{6}=1=k[/tex]

The set of ordered pairs (2, 2), (4, 4), (6, 6) show equivalent ratios.

For option 3,

(3, 1), (4, 1), (5, 1)

[tex]\dfrac{1}{3}\neq \dfrac{1}{4}[/tex]

For option 4,

(4, 1), (8, 2), (12, 3)

[tex]\dfrac{1}{4}=\dfrac{2}{8}=\dfrac{3}{12}=k[/tex]

The set of ordered pairs (4, 1), (8, 2), (12, 3) show equivalent ratios.

For option 5,

(2, 1), (4, 3), (5, 4)

[tex]\dfrac{1}{2}\neq \dfrac{3}{4}[/tex]

So, sets of ordered pairs in options 1, 3 and 5 does not show equivalent ratios.

Therefore, the correct options are 2 and 4.

131 is prime. So the answer is A

Step-by-step explanation:

Remark

x is one of the legs. The other one is √65

Equation

x^2 + (√65)^2 = 14^2

Solution

x^2 + 65 = 196                 Subtract 65 from both sides

x^2 = 196 - 65

x^2 = 131                          Take the square root of both sides.

√x^2 = √131

x = √131

The length of a rectangle is 5(x+2) units. The width of the rectangle measures (2x-1) units. Set up and simplify an alegebraic expression to find the difference between the rectangles length and width.

Answers

Answer:

(3x + 11) units

Step-by-step explanation:

The length of a rectangle is 5(x+2) units.

The width of the rectangle measures (2x-1) units.

The difference between the rectangles length and width is given as:

Length - Width

(5(x + 2) - (2x - 1) units

(5x + 10 - 2x + 1) units

(5x - 2x + 10 + 1) units

(3x + 11) units

Therefore, the algebraic expression for the difference between the rectangles length and width is given as:

(3x + 9) units

how many units apart are (3.1,-1) and (4.1,-1)

Answers

Answer:

The points are 1 unit apart.

Step-by-step explanation:

Given points are:

(3.1,-1) and (4.1,-1)

Distance formula is given by;

Distance between points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Where,

[tex](x_1,y_1)[/tex] = Coordinates of first point

[tex](x_2,y_2)[/tex] = Coordinates of the second point

Putting the values,

Distance = [tex]\sqrt{(4.1-3.1)^2 + (-1-(-1))^2[/tex]

Distance = [tex]\sqrt{(1)^2 + (-1+1)^2[/tex]

Distance = [tex]\sqrt{(1)^2}[/tex]

Distance = 1 unit

Hence,

The points are 1 unit apart.
