[tex]f(x) = 2x + 3[/tex]

And

[tex]g(x) = 2 \times {3}^{x} \\ [/tex]

_________________________________

To find the y-intercept of any equation just need to put 0 (( zero )) instead of the x in the equation...

_________________________________

In f ( x ) :

[tex]y - intercept = f(0)[/tex]

[tex]f(x) = 2x + 3[/tex]

[tex]f(0) = 2(0) + 3[/tex]

[tex]f(0) = 3[/tex]

Thus :

[tex]y - intercept = 3[/tex]

##############################

In g ( x ) :

[tex]y - intercept = g(0)[/tex]

[tex]g(x) = 2 \times {3}^{x} [/tex]

[tex]g(0) = 2 \times {3}^{0} [/tex]

[tex]g(0) = 2 \times 1[/tex]

[tex]g(0) = 2[/tex]

Thus :

[tex]y - intercept = 2[/tex]

_________________________________

The positive difference in the y-intercept value of f ( x ) and g ( x ) is :

[tex] |3 - 2| = |1| = 1[/tex]

This simply means that, on a scale of 1 - 100, there is a 20 percent chances that, when Aaron tunes into the radio frequencies in search of a station, he will be able to get one station playing a commercial at that particular time.

For example, at 11:00am each day, him tuning into his favorite radio station would be 20 percent possible to meet one playing a commercial.

Step-by-step explanation:

Using the concept of relative frequency, the interpretation is that over a large number of days, in around 20% of the times he tunes is his favorite station a commercial will be playing.

Step-by-step explanation:

The prism width is (1 3/4)/(1/4) = (7/4)/(1/4) = 7 cubes.

The prism length is (1 1/4)/(1/4) = (5/4)/(1/4) = 5 cubes.

The prism height is (3/4)/(1/4) = 3 cubes.

Then the total number of small cubes required to fill the prism is ...

  V = LWH = (5)(7)(3) = 105

It takes 105 small cubes to make the larger prism.

Answer:

3 (9e + 8)

explanation:

3 x 9e = 27e

and

3 x 8 = 24

Both are multiplyed by 3 so your first number is

3 ( ?e + ?)

then the 2ed has e beside so i know thats 9

3 ( 9e + ?)

The final one is 8. 3 x 8 = 24 so there is 24 in the question so the last is 8

3 (9e + 8)  

3(9e+8) is the  expression that is equivalent to 27e + 24.​

An expression is combination of variables, numbers and operators.

We need to find the equivalent fraction of 27e + 24.​

For this let us find the factors of 27 and 24

Factors of 27 are 1,3,9,27

Factors of 24 are 1,2,3,4,6,8,12,24

The greatest common factor is 3.

So in the expression 27e+24 take 3 as common

3(9e+8)

Hence 3(9e+8) is the  expression that is equivalent to 27e + 24.​

Lets use process of elimination

Step-by-step explanation:

1. The order of the coordinate grid is like the alphabet. a comes before b,  x comes before y.

2. Step 1 This eliminates 3 and 4. So we are left with 2 and 1.

3. It is not 1 because there is no a and b coordinate. There is only a Y and x one.

4. 4 is on the x axis, 6 is on the y axis.

5. Thus, the answer is 2.

Answer:

The length of third side is: 6.3

Step-by-step explanation:

Given triangle is a right triangle where

Base = ?

Perpendicular = 5

Hypotenuse = 8

Let x be the base

As it is a right-angled triangle, Pythagoras theorem can be used to find the third side

[tex]Hypotenuse^2 = Base^2 + Perpendicular^2[/tex]

Putting the known values

[tex](8)^2 = x^2 + (5)^2\\x^2 = (8)^2-(5)^2\\x^2 = 64-25\\x^2 = 39\\[/tex]

Taking square root on both sides

[tex]\sqrt{x^2} = \sqrt{39}\\x = 6.24499[/tex]

Rounding off to the nearest 10th

Base = 6.3

Hence,

The length of third side is: 6.3

Answer: it will be 6 ounces of frozen yogurt and 10 ounces of orange juice.

Step-by-step explanation:

3 parts frozen yogurt

5 parts orange juice For a total of 8 parts divided by 16 ounces = 2 Multiply 3 fy x 2= 6 ounces And multiply 5 oj x 2= 10 ounces

There are 6 ounces of frozen yogurt and 10 ounces of orange juice does he need to get a total of 16 ounces​.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

We have to given that;

The recipe calls for three part frozen yogurt to five part orange juice.

Here, The ratio of frozen yogurt to orange juice = 3 : 5

Hence, To get a total of 16 ounces​, we can formulate;

⇒ 3x + 5x = 16

⇒ 8x = 16

⇒ x = 2

Hence, The amount of ounces of frozen yogurt = 3x

                                                                         = 3 × 2

                                                                         = 6

And, The amount of ounces of orange juice = 5x

                                                                    = 5 × 2

                                                                    = 10

Thus, There are 6 ounces of frozen yogurt and 10 ounces of orange juice does he need to get a total of 16 ounces​.

Answer:

2.5 hours

Step-by-step explanation:

Given

The information in the attachment

To solve this question, first we calculate the slope

[tex](t_1,B_1) = (1,19,5\%)[/tex]

[tex](t_2,B_2) = (2,13\%)[/tex]

The slope is:

[tex]m = \frac{B_2 - B_1}{t_2 - t_1}[/tex]

[tex]m = \frac{13\% - 19.5\%}{2-1}[/tex]

[tex]m = \frac{-0.065}{1}[/tex]

[tex]m = -0.065}[/tex]

The equation is calculated as:

[tex]B - b_3 = m(t - t_3)[/tex]

Where

[tex]m = -0.065}[/tex]

[tex](t_3,B_3) = (3,6.5\%)[/tex]

This gives

[tex]B - 6.5\% = -0.065(t - 3)[/tex]

[tex]B - 6.5\% = -0.065t +0.195[/tex]

[tex]B -0.065 = -0.065t +0.195[/tex]

[tex]B = -0.065t +0.195 +0.065[/tex]

[tex]B = -0.065t +0.26[/tex]

To calculate the time at 9.75%.

We take B = 9.75%

So, we have:

[tex]9.75\% = -0.065t +0.26[/tex]

Solve for t

[tex]0.0975= -0.065t +0.26[/tex]

Collect Like Terms

[tex]0.065t= -0.0975 +0.26[/tex]

[tex]0.065t= 01625[/tex]

[tex]t = 0.1625/0.065[/tex]

[tex]t = 2.5[/tex]

Hence, it will take 2.5 hours.

Answer:

Slope: 5/2 or 2.5

Step-by-step explanation:

1. Put both of the y values together on the top of a fraction and the x values on the bottom.

It should look like this: [tex]\frac{8-3}{-3-(-5)}[/tex]

2. Now you need to simplify the y and x values. -3-(-5) is equal to 2 and 8-3 is 5.

I should now look like this: [tex]\frac{5}{2}[/tex]

3. That could be your answer as a fraction. Or you can take the extra step and  actually divide them. 5 divided by 2 is 2.5.

In the end, you will have a result of 5/2 or 2.5. That it the slope of the line of the points (-5,3) and (-3,8). I hope this helps and you actually understand it. Remember, don't cheat! Always do your best! Good luck!

The given points are:

As we know,

Slope, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

By substituting the values, we get

               [tex]= \frac{8-3}{-3-(-5)}[/tex]

               [tex]= \frac{5}{-3+5}[/tex]

               [tex]= \frac{5}{2}[/tex]

Answer:

E(X) = 6

Var(X) = 3.394

Step-by-step explanation:

Let X represent the number of carp caught out of the 20 fishes caught. Now, if we are to assume that each

of the (100, 20) ways to catch the 20 fishes will be equally likely.

Thus, we can say that X fulfills a hypergeometric

distribution with parameters as follows;

n = 20, N = 100, k = 30

Formula for expected mean value in hypergeometric distribution is;

E(X) = nk/N

E(X) = (20 × 30)/100

E(X) = 6

Formula for variance is;

Var(X) = (nk/N) × [((n - 1)(k - 1)/(N-1))) + (1 - nk/N)]

Var(X) = ((20 × 30)/100) × [((20 - 1)(30 - 1)/(100 - 1)) + (1 - (20 × 30/100)]

Var(X) = 6 × 0.5657

Var(X) = 3.394
