Please help me I’m bad at math

Mathematics
1 answer:
puteri [66]3 years ago
4 0

The range is the inteval including all possible answer.

Boys' answers range from 3 to 10, whereas girls' anwers range from 5 to 9. So, the range is greater for the boys, because

10-3=7>4=9-5

As for the average, we have to sum all results and divide by the number of results:

A_{boys} = \dfrac{3+6+7+7+8+8+8+8+9+10}{10} = 7.4

A_{girls} = \dfrac{5+6+6+6+7+7+7+8+9}{10} = 6.1

adult tickets for the fall play cost $6 and students cost $3. the drama club so 25% more students tickets than adult tickets to
Anton [14]
S = the number of student tickets sold a = the number of adult tickets sold The drama class sold 25 more student tickets than adult tickets to the fall play s = a + 25 The class collected $660 from ticket sales: 6s + 3a = 660 divide both sides by 3 2s + a = 220 by solving the system of equations s = a + 25 2s + a = 220 we find s = 81.67 student tickets a = 56.67 adult tickets

I hope this helps you! Let me know if you have any more questions. If possible please check my page for my question!

Diff. / Original amount= % of increase or decrease
V125BC [204]

Answer:

% increase =\frac{\text{ Increased number -Original number }}{\text{Original number}} \times 100\%

% decrease =\frac{\text{ Original number - Decreased number }}{\text{Original number}} \times 100\%

Step-by-step explanation:

Percentage Increase:

Let there be an original number. If it increased to a certain value we can calculate the percentage increase value with the help of following formula:

% increase =\frac{\text{ Increased number -Original number }}{\text{Original number}} \times 100\%

Percentage Decrease:

Let there be an original number. If it decreases to a certain value we can calculate the percentage decrease with the help of following formula:

% decrease =\frac{\text{ Original number - Decreased number }}{\text{Original number}} \times 100\%

Write the equation for g (x)
belka [17]

Answer:

g(x) = (-1/25)x + (203/25)

Step-by-step explanation:

The general equation for a line is slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept.

We know that perpendicular lines have opposite-signed, reciprocal slopes of the original line. Therefore, if the slope of f(x) is m = 25, the slope of g(x) must be m = (-1/25).

To find the y-intercept, we can use the newfound slope and the values from the given point to isolate "b".

g(x) = mx + b                                    <----- General equation

g(x) = (-1/25)x + b                             <----- Plug (-1/25) in "m"

8 = (-1/25)(3) + b                               <----- Plug in "x" and "y" from point

8 = (-3/25) + b                                  <----- Multiply (1/25) and 3

200/25 = (-3/25) + b                       <----- Covert 8 to a fraction

203/25 = b                                      <----- Add (3/25) to both sides

Now that we know both the values of the slope and y-intercept, we can construct the equation of g(x).

g(x) = (-1/25)x + (203/25)
