The independent variable is the cost of riding the subway.

The dependent variable is the number of times she can ride the subway.

The independent variable is the variable whose value is given. It is the value of the independent variable that determines the dependent variable.  The dependent variable is the variable whose value is determined by changes in the independent variable.

In this question, the cost of each ride is given. There is little or nothing Nina can do to change the price of the subway ride. Thus, it is the independent variable. The total amount of rides Nina can go on is dependent on the cost per ride and the total amount she has. Thus, it is the dependent variable.

Okay, here we have this:

Considering the provided information, we are going to calculate the expected value for the game, so we obtain the following:

We will substitute in the following formula:

Expected Value=(Black Gain)*Black Chance (Gold Gain)*Gold Chance+(Silver Gain)*Silver Chance

Expected Value=(-1)*(25/33)+(3)*(1/33)+(2)*(7/33)

Expected Value≈-0.24

Finally we obtain that the expected value is approximately $-0.24.

The given equation is

The y-intercept of the new line is -10.

We have to find a new parallel line to the given equation, which means they must have the same slope.

Remember that the coefficient of x is the slope, so the slope of the given line is -1/4. This means the new line has a slope fo -1/4 because it's parallel.

So, we know that the new line has a slope of -1/4 and its y-intercept is -10. We use the slope-intercept form to write the equation.

To convert 81 degrees to radian, we will apply the conversion:

1 π rad = 180°

let the 81° in rad = y

1 π rad = 180°

y = 81°

cross multiply:

1π rad (81) = 180 y

To get y, we divide both sides by 180:

The easiest expression to simplify by using the associative property is expression "b", since there is an addition already set (120 + 80 =200) to be performed.

'The other expressions involve more steps.

Step 1

let x represents the number of minutes.

hence:

Plan A costs $19 plus an additional $0.07 for each minute of calls

Plan B costs $12 plus an additional $0.11 for each minute of calls

Step 2

Answer:

-3 because (-1,-7) and (1,-13) takes -6 to get from -7 to -13 and 2 to get from -1 to 1. -6/2 is -3, so the slope/answer is -3.

Step-by-step explanation:

Answer:

Formula for finding slope is given as y2-y1 ÷ x2-x1 or y1-y2 ÷ x1-x2, where x and y are the coordinates of the points.

Slope = -13-(-7) ÷ 1-(-1)

= (-13+7) ÷ (1+1)

= -6 ÷ 2

= -3

The three equations that have the same value of x as 3/5(30 x minus 15) = 72 are:

Equations are mathematical statements that show the equality of mathematical expressions.

These statements claim that two or more expressions are equal or equivalent.

To show this equality, the expressions are joined with the equal sign (=).

3/5(30x - 15) = 72

= 18x - 9 = 72

18x = 81

x = 4.5 (81/18)

ANSWER

EXPLANATION

We want to write the equation of the line that passes through the point (-3, 7) and is parallel to the y-axis.

The general equation of a line is given as:

where m =slope

c = y intercept

A line parallel to the y-axis is a vertical line. The slope of a vertical line is undefined and so the equation of a vertical line is given as:

where a is the x coordinate of any point that it passes through.

Therefore, since the line passes through (-3, 7), the equation of the line is:

Let the numbers over par is (+) and the numbers under par is (-)

he scores 5 over par, 3 under par, 6 over par, and 3 under

par.

so, the expression is : (5) + (-3) + (6) + (-3)

So, the result will be:

over par = 5 + 6 = 11

under par = 3 + 3 = 6

subtract under par from over par

so, 11 - 6 = 5

So, the Cameron's score = 5

The batch of sweet should contain 4 lb of Brand A granola

The batch of sweet should contain 6 lb of Brand B granola

Total amount of sweet items = 10 lb

Let the amount of brand A granola be x

Amount of brand B granola = 10 - x

Amount of nuts and dried fruits in the total sweet items = 22% of 10

Amount of nuts and dried fruits in the total sweet items = 0.22 x 10

Amount of nuts and dried fruits in the total sweet items = 2.2lb

Amount of nuts and dried fruits in brand A granola = 25% of x

Amount of nuts and dried fruits in brand A granola = 0.25x

Amount of nuts and dried fruits in brand B granola = 20% of (10-x)

Amount of nuts and dried fruits in brand B granola = 0.2(10 - x)

Amount of nuts and dried fruits in brand A granola + Amount of nuts and dried fruits in brand B granola = Amount of nuts and dried fruits in the total sweet items

0.25x + 0.2(10 - x) = 2.2

0.25x + 2 - 0.2x = 2.2

Collect like terms

0.25x - 0.2x = 2.2 - 2

0.05x = 0.2

x = 0.2 / 0.05

x = 4 lb

The batch of sweet should contain 4 lb of Brand A granola

Amount of brand B granola = 10 - x

Amount of brand B granola = 10 - 4

Amount of brand B granola = 6 lb

The batch of sweet should contain 6 lb of Brand B granola

SOLUTION

(a) The first plan cost $55 and an additional $0.13 per mile driven,

while the second plan cost $48 and an additional $0.17 per mile driven

Let the amount of driving be x

Then, this means that for the first plan we have

And the second plan becomes

So, for the plans to cost the same for a particular amount of driving x, it means that

Collecting like terms we have

Hence the two plans cost the same at 175 miles

(b) The cost when the two plans cost the same is

Hence the answer is $77.75

-Morgan is making ----------------> 2 cookie recipes.

Recipe A ---> A = 2RecipeB -(1/3) 2RecipeB

-She needs-----------> Recipe A + Recipe B = 4 1/6 cups of sugar

Now, we have a system of equations:

(1) A = 2B -(1/3)2B

(2) A + B = 4 1/6

Multiplying both sides of (1) by 3:

3A = 6B - B

Then, the function is shifted down 3 units means you subtract 3 to f(x).

And the function is shifted to the right 1 unit means you subtract 1 from the argument of f(x), this is "x". Therefore, the new function is:

Answer:

We have a deck of 52 cards.

We have to calculate the probability that when a card is randomly drawn from the deck, this cart is a red four.

There is only one red four in the deck. Then, if we calculate the probability of an event as the quotient between the number success events (getting a red four, in this case) and the total possible events (getting any card), we will get:

As there is only one card in the deck that gives a success event within the 52 cards, the probability is 1 in 52.

Answer: the probability is 1/52.

The complete table of values for the x values in function h(x) is

x        | -2    -1    0    1    2

h(x)   |  3     2     1      0   -1

From the question, the definition of the function is given as

h(x) = 1 - x

Also, from the table of the values;

We have the following x values

x = -2, -1, 0, 1 and 2

The next step is that

We substitute each value of x in the equation h(x) = 1 - x

So, we have

When x = -2

h(-2) = 1 + 2

Evaluate

h(-2) = 3

When x = -1

h(-1) = 1 + 1

Evaluate

h(-1) = 2

When x = 0

h(0) = 1 + 0

Evaluate

h(0) = 1

When x = 1

h(1) = 1 - 1

Evaluate

h(1) = 0

When x = 2

h(2) = 1 - 2

Evaluate

h(2) = -1

When represented on a table of values, we have

8 x 57 = 456

y = 2x - 5 Eq(1)

6x - 2y= 20 Eq(2)

We are going to use the elimination method to solve the system.

y-2x = -5 Transpose x to the othe side in Eq(1)

2y - 4x = -10 Multiply all terms of Eq(1) by 2. Then add Eq(1) to Eq(2)

2y - 4x = -10

+ -2y +6x= 20

----------------------

2x = 10 Operating like terms

x= 10/2 Isolating x

x = 5

Replacing x in Eq(1)

y = 2*(5) -5

y= 10 - 5 = 5

The answer is the point with coordinates ( 5 (x-coordinate) , 5(y-coordinate)).

The measure of this angle is 65°

The measure of this angle is 60°

Explanation:

1) From the diagram the angle is between 10° and 75°

One of the arrows is on 10°

the other arrow is on 75°

the measure of the angle is between the two angles, so we subtract the smaller one from the bigger one

The angle in degrees is the difference between the 75° and 10°

= 75 - 10

= 65°

The measure of this angle is 65°

2) The second diagram is from 0° to 60°

Difference between them = 60° - 0°= 60°

The measure of this angle is 60°
