Give an example of two events that are not mutually exclusive.​

Answer:

A. -25x + 7

Step-by-step explanation:

First, to answer this question, we will combine the two sides of the equation:

(-9x + 13) + (-16x - 6)

Now, we take away the parentheses and add like terms:

-9x + 13 + -16x - 6 =

-25x + 7

So, the answer would be A. -25x + 7

Answer:

32 people came in blue cars and 6 people came in red cars

Step-by-step explanation:

Technically, all 48 people came in red or blue cars, but I'm assuming that's not what the question is asking.

To find how many people came in blue cars, we do 2/3*48 which is equal to 32 people.

To find how many people came in red cars, we do 1/8*48 which is equal to 6 people.

Answer:

$513.75

Step-by-step explanation:

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.

$498.75 + $2.50 × x

If he works 6 hours on the weekend in addition to the 35 hours during the week:

$498.75 + $2.50 × 6

= $498.75 + $15

= $513.75

Answer:

Step-by-step explanation:

when you put them together you get 0

Answer:

9 is a zero of h(x). C. Correct

Step-by-step explanation:

We want to find the zeros of the function

[tex]h(x) = (x^2 - 81)(x + 4)[/tex]

The zeros are the values of x that make h(x)=0, thus we need to solve the equation:

[tex](x^2- 81)(x + 4)=0[/tex]

Factoring:

[tex](x^2 - 81)=(x-9)(x+9)[/tex]

[tex](x-9)(x+9)(x + 4)=0[/tex]

This equation has 3 solutions:

x=9, x=-9, x=-4

A. 0 is not a zero of h(x). Incorrect

B. 4 is not a zero of h(x). Incorrect

C. 9 is one of the zeros of h(x) calculated above. Correct

D. 81 is not a zero of h(x). Incorrect

Answer:

C) 9

Answer:

13

Step-by-step explanation:

1. Collect like-terms

-23=-a-10

2.Isolate variable

-13=-a

a=13

Answer:

A=13

Step-by-step explanation:

-23=-2a-10+a

add 10 to -23 which is now

-13=-2a+a

now add -2a and a together to get -1a

-13=-1a

divide -1 into both sides to get

13=a

Answer:

We are 95% confident that the true proportion of U.S. adults who live with one or more chronic conditions is between 39.7% and 46.33%

Step-by-step explanation:

From the question we are told that

  The  sample  proportion is [tex]\r p = 43\%  = 0.43[/tex]

   The  standard error is [tex]SE =  0.017[/tex]

Given that the confidence level is 95%  then the level of significance is mathematically represented as  

      [tex]\alpha =  (100-95)\%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as

     [tex]E = Z_{\frac{\alpha }{2} } *  SE[/tex]

=>    [tex]E = 1.96 *  0.017[/tex]

=>     [tex]E = 0.03332 [/tex]

Generally 95% confidence interval is mathematically represented as

      [tex]\r p -E <  p <  \r p +E[/tex]

=>   [tex]0.43 -0.03332 <  p <  0.43 + 0.03332[/tex]

=>    [tex] 0.39668 <  p <  0.46332[/tex]

Converting to percentage

[tex] (0.39668 * 100)<  p <  (0.46332*100)[/tex]        

[tex] 39.7\% <  p < 46.33 \%[/tex]

What's Yo Question ?

Answer:

y = 2/5x + 24/5

Step-by-step explanation:

y - 4 = 2/5(x - (-2))

y - 4 = 2/5(x +2)

y - 4 = 2/5x + 4/5

y = 2/5x + 4/5 + 4

y = 2/5x + 24/5

Answer:

y = 5x + 1

Step-by-step explanation:

Visually you can see the slope is -1/5, perpendicular just means opposite inverse so -1/5 becomes 5. Line crosses the y-intercept at point (0, 1).

y = mx + b

y = 5x + 1

Answer: D

Step-by-step explanation: The 4 skirts cost are unknown which makes up the 4x and the extra pair of shoes adds on to the cost by 35.67.

He spent 1 49/60 total hours on his homework altogether

There are twelve months in a year, and he pays $1000 a month, so we get [tex]\$1000*12 = $12,000[/tex] spent in a year. He originally needed to spend $36,000, so he has [tex]\$36,000-\$12,000 = \$24,000[/tex] left.

Please mark as Brainliest if you found this helpful.

Answer:

He payed 12,000 in one year

John has to pay $24000

Step-by-step explanation:

Car cost = $36,000

He gave Monthly = $1000

How much money did he give in a year?

1 year = 12 months

So

$1000 x 12 = 12,000

How does he have balance?

$36,000 - $12,000 = $24,000

John payed $12000 in one year, and has to pay $24000 more to own the car.

Hope you understand

Answer:

A = [tex]\frac{b}{f^2+2H}[/tex]

Step-by-step explanation:

Given equation is,

b = f²A + 2HA

To solve this equation for the value of A we will isolate A in one side of the equation.

b = A(f² + 2H)

By dividing the equation by (f² + 2H) on both the sides of the equation.

[tex]\frac{b}{f^2+2H}=\frac{A(f^2+2H}{(f^2+2H)}[/tex]

A = [tex]\frac{b}{f^2+2H}[/tex]

Therefore, answer will be A = [tex]\frac{b}{f^2+2H}[/tex]

Answer:

x = 60 degrees

Step-by-step explanation:

In a triangle, all the inside angles should add up to 180 degrees, so to get this question, we have to add the angles we know and then subtract 180 by the number we get:

68 + 52 = 120

180 - 120 = 60

So, x = 60 degrees

Hope this helps :)

the following are my reminders in using this module

  By the property of alternate interior angles, Option (1) is the correct statement.    

    From the figure attached,

    Property of the alternate angles states, if two parallel lines are cut by a transversal, then the alternate angles are congruent.

By this property,

 Lines XW and YZ are the parallel lines intersected by a transversal WY.

Here, ∠XWY and ∠ZYW represent the interior angles between the parallel lines and the transversal.

 Therefore, interior alternate angles ∠XWY and ∠ZYW will be congruent.

Hence, Option (1) will be the correct option.

Answer:

If Kasey bought one drink, she will be able to buy 6 food items

Step-by-step explanation:

We know Kasey has $8 and if she bought one drink, she will have $7.5

We have to find how many food items she can buy (all of them are $1.25)

$7.5/1.25= 6 food items

If Kasey bought one drink, she will be able to buy 6 food items

Hope this helps!

Answer:

6 items

Step-by-step explanation:

8.00 - 0.50 = 7.50

She has $7.50 to spend on food after buying one drink

7.50 ÷ 1.25 = number of food items she can buy

7.50 ÷ 1.25 = 6
