Answer:

2/15

Step-by-step explanation:

Step one:

given data

sample space

1 elephant,

4 bears,

3 cats, and

2 dogs.

sample size= 1+4+3+2= 10

Required:

By selecting without replacement, the probability that she chooses a bear both times

Step two:

the first event= Pr(bear)= 4/10= 2/5

the second event, the sample size is now 9 and the number of bears is now 3

Pr(bear)= 3/9= 1/3

Hence, the probability that she chooses a bear both times

= 2/5*1/3

=2/15

Answer:

B. 9

Step-by-step explanation:

12 times 3/4 is 9

Answer:

it takes 4 of the 3/4 servings to make a whole number and it's 3 cups.

12/3= 4 and 4*4= 16

so 16 children can eat ice cream

or you could do 12/0.75= 16

you would do that because 3/4=0.75

you would divide and not multiply because you're seeing how many times 0.75 can go into 12

Answer:

187.5 km

Step-by-step explanation:

For every 2cm there is 25km, So 2cm/25km. Now you are given 15cm, and you need to find the actual distance in km. Set up the fraction 2cm/25km=15cm/Xkm and solve for X using cross multiplication as follows:

2x=25(15), so 2x=375, X=187.5 km.

Answer:

y=6x+4.2

Step-by-step explanation:

rakka flakka told me

Answer:

17

Step-by-step explanation:

f(x) is the same as y=. "What is f(5)" is the same as saying what is y=3x + 2 when x is 5.

Either way, you are going to replace x with is numerical value, which is 5, and then solve.

y = 3(5) + 2

y = 15 +2

y = 17

f(5) = 17

so whats the question then?

Step-by-step explanation:

Answer:

19 years

Step-by-step explanation:

Initial height of tree when Samiya bought the tree = 3 inches

Growth in the height of tree every year = 5 inches

Number of years = [tex]y[/tex]

Growth in the height of tree in [tex]y[/tex] years = 5 inches multiplied by number of years

Growth in the height of tree in [tex]y[/tex] years = 5[tex]y[/tex] inches

To find:

Number of years taken by the tree to be 8 ft or 96 inches.

Solution:

The equation for height of tree after [tex]y[/tex] years can be written as:

3 + 5[tex]y[/tex] which is to be compared with 96 inches.

Therefore, the equation is:

[tex]3 + 5y = 96\\\Rightarrow 5y=93\\\Rightarrow y \approx 19[/tex]

Therefore, it will take 19 years for the tree to reach a height of 96 inches.

B. The slope is -2, and the y-intercept is 12

Step-by-step explanation:

Answer:

  -8/5

Step-by-step explanation:

When you solve for y, the slope of the line is the x-coefficient. For the given line, that is ...

  8y = 5x +11 . . . . . add 5x

  y = 5/8x +11/8 . . . . divide by 8

The given line has a slope of 5/8. The perpendicular line will have a slope that is the opposite of the reciprocal of this:

  -1/(5/8) = -8/5 . . . . slope of perpendicular line

Answer:

The slope of the perpendicular line will be -8/5, or -1.6

Step-by-step explanation:

First we need to rearrange the equation to show the slope, putting in the format y = sx + c:

[tex]8y - 5x = 11\\8y = 5x + 11\\y = \frac{5}{8}x + \frac{11}{8}[/tex]

So the given line has a slope of 5/8.

A line perpendicular to that will have a negative reciprocal of that slope, so it's slope will be -8/5.

Answer:

Range[4,24,44,64,84,104,124]

Step-by-step explanation:

CHECK THE COMPLETE QUESTION BELOW;

A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs

20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in

pounds can be represented by f x( ) = 20x + 4.

What is the range of the function for this situation?

The range of a function can be defined as the difference between the maximum and minimum function. From the question, we can deduced that the minimum function of X is 0 and no plate is added, and the maximum is 6

The given function is

f(x) = 20x + 4 =

f(0) = 20(0) + 4

= 4

f(6) = 20(6) + 4

= 124

Which means the range is within 4 and 124.

But we are told from the question that Each pair of plates weighs 20 lb, which means there is difference of 20ib each between 4 and 24

Then we can compute the range as [4,124] or (4,24,44,64,84,104,124)

Answer:

a) The cost of producing 40 pretzels is $656

The income for selling 40 pretzels is $116

b) They sold 90 pretzels

c) They must sell 240 pretzels to break-even

Step-by-step explanation:

Linear Models

A linear model is an equation that describes a relationship between two quantities that have a constant rate of change.

One of the most-used equations of linear models is the slope-intercept form, written as:

y = mx + b

Where m is the slope of the graph of the line and b is the y-intercept.

The total cost of producing soft pretzels is divided into two parts:

* A fixed cost of $648 to set up their stand for the entire regatta.

* A variable cost of $0.20 per each pretzel.

Thus, the cost function can be written as:

C(x)=648+0.20x

Where x is the number of pretzels produced.

The students sell each pretzel for $2.90. This means the income (revenue) function for selling x pretzels is:

R(x)=2.90x

a) The cost of producing x=40 pretzels is:

C(40)=648+0.20*40

C(40)=648+8

C(40)=656

The cost of producing 40 pretzels is $656

The income is:

R(40)=2.90*40=116

The income for selling 40 pretzels is $116

b) If the income from selling pretzels is R=$261, then:

2.90x=261

Solving for x:

x = 261/2.90

x = 90

They sold 90 pretzels

c) To break-even the total cost and the income must be equal:

2.90x=648+0.20x

Subtraction 0.20x:

2.70x=648

Dividing by 2.70:

x = 648/2.70

x = 240

They must sell 240 pretzels to break-even

Answer:

$26.45.

Step-by-step explanation:

First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $23.00 meal cost is.This is always done by multiplying 0.15 by $23.00, or

0.15 x $23.00=$3.45.

So, the amount of tip you are going to leave is $3.45.

This makes the total cost of your meal (to write on your charge slip or other payment)

$23.00 + $3.45 = $26.45.

Answer:

40/6

Answer:

The answer is A

Tom will have to sell at least 10 TVs to get the bonus and to get $1,500

Step-by-step explanation:

Total: The same or above 1500

Tom gets paid 100 for each TV = 100t

He can get a 500 bonus by selling a certain amount = 500

100t + 500 ≥ 1,500

100t + 500 - 500 ≥ 1500 - 500

100t ≥ 1000

100t ÷ 100 ÷ 1000 ÷ 100

t ≥ 10

Tom will have to sell at least 10 TVs to get the bonus and to get $1,500

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
