what is the slope for the graph y - 4x =-2 ?

Answer:

Letter D! That's the answer

Answer:

C. y = 4

Step-by-step explanation:

\( \sin \: 30 \degree = \frac{y}{8} \\ \\ \frac{1}{2} = \frac{y}{8} \\ \\ y = \frac{8}{2} \\ \\ y = 4\)

Answer:

Inverse Function = 4x -8

Step-by-step explanation:

replace x with y and replace x with y

solve for y (meaning isolate y)

y=(1/4x) +2

x= (1/4y) +2

x-2 = 1/4y

multiply by 4 on each side to remove 1/4 from the right side

4(x-2) = y

y= 4(x-2)

y= 4x -8

Inverse Function = 4x -8

Hi hi ok so heres how you do this:

This is a right triangle cause of the lil' red angle indication.

So, we use Pythagorean theorem.

a^2+b^2=c^2

Now, we have a and c(or b and c. A and B are interchangeable)

10^2+b^2=26^2

100+b^2=676

676-100=576

Now, square root of 576 is 24.

The expected profit from the contract, if both firms refrain from spending anything on lobbying, is $2 million.

In this scenario, if both firms choose not to spend anything on lobbying, the winner will be determined by a coin flip, resulting in a 50% chance for each firm to win the contract. The economic profit from winning the contract is $5 million.

Since each firm has a 50% chance of winning, the expected profit can be calculated by multiplying the probability of winning (0.5) by the economic profit ($5 million), resulting in an expected profit of $2.5 million. Therefore, the expected profit from the contract, if both firms refrain from spending anything on lobbying, is $2 million (rounded to the nearest million).

Answer:

13 cm

Step-by-step explanation:

1.2m = 120cm

120cm - 107cm = 13cm taller

John is 13 centimeters taller than Xavier.

The methodology to convert inches to mm is relatively simple. To convert meters to centimeters, you must multiply the unit by 100.

For example, if you have to convert 5 meters to centimeters, you need to multiply 5 by 100.

Therefore, 5 meters = 5 × 100= 500 centimeters

To find the height difference between John and Xavier in centimeters, we need to first convert John's height to centimeters.

Since 1 meter is equal to 100 centimeters, John is 1.2 x 100 = 120 centimeters tall.

The height difference between John and Xavier is :

⇒ 120 - 107

Apply the subtraction operation, and we get

⇒ 13 centimeters.

Therefore, John's height is 13 centimeters greater than Xavier's.

The probability of having a wireless mouse is 0.4 , the probability of not having a wireless keyboard is 0.3, and 0.2 is the probability of having both a wireless mouse and keyboard.

Using proper notation, we can denote the events as follows

Event A: Someone has a wireless mouse

Event B: Someone has a wireless keyboard

Then we have the following probabilities:

P(A) = 0.4 This signifies the probability that someone has a wireless mouse.

P(not B) = 0.3 This signifies the probability that someone does not have a wireless keyboard. Note that "not B" means the complement of event B, i.e., the event that someone does not have a wireless keyboard.

P(A and B) = 0.2 This signifies the probability that someone has both a wireless mouse and a wireless keyboard. The notation "A and B" means the intersection of events A and B, i.e., the event that someone has both a wireless mouse and a wireless keyboard.

The total number of arrangements possible if A and B must not sit together:

=  3600

Now, According to the question:

The no. of circular arrangements of n distinct items = (n-1)!

If A,B,C,D,E,F,G and H are the 8 persons to be seated around the table and A,B the 2

particular persons who must not sit together.

The total no.of circular arrangements for 8 persons = (8-1)! = 7! = 5040 --(1)

The no. of circular arrangements possible if A and B were to sit together = 6! (considering A and B as a single pair).

But, A and B can interchange their positions.

Hence, the no. of arrangements =6!×2=720×2=1440−−−−>(2)

So, the total number of arrangements possible if A and B must not sit together, = (1) - (2)

The probability of getting a sum of 9 or higher when rolling two dice is 10/36, which can be simplified to 5/18 or approximately 0.2778.

For the probability that the sum of two fair six-sided dice is 9 or higher, we need to determine the total number of possible outcomes and the number of favorable outcomes.

The total number of possible outcomes when rolling two dice is given by 6 * 6 = 36, as each die has 6 possible outcomes.

Now, let's determine the number of favorable outcomes. We need to find the combinations of numbers on the two dice that result in a sum of 9 or higher.

The possible combinations for a sum of 9 are (3, 6), (4, 5), (5, 4), and (6, 3), which gives us 4 favorable outcomes.

The possible combinations for a sum of 10 are (4, 6), (5, 5), and (6, 4), which gives us 3 favorable outcomes.

The possible combinations for a sum of 11 are (5, 6) and (6, 5), which gives us 2 favorable outcomes.

Finally, the possible combination for a sum of 12 is (6, 6), which gives us 1 favorable outcome.

Adding up the favorable outcomes, we have 4 + 3 + 2 + 1 = 10.

Therefore, the probability of getting a sum of 9 or higher when rolling two dice is 10/36, which can be simplified to 5/18 or approximately 0.2778.

If the perimeter of the parallelogram is 102 feet, then the value of m is 12.75

The perimeter of the parallelogram = 102 feet

The perimeter of the parallelogram = 2(l + w)

Where l is the length and w is the width of the parallelogram

The length of the parallelogram = 3m

The width of the parallelogram = m

Substitute the values in the equation of the perimeter

102 = 2(3m + m)

102 = 2(4m)

102 = 8m

m = 102 / 8

Divide the terms

m = 12.75

Hence, if the perimeter of the parallelogram is 102 feet, then the value of m is 12.75

Step-by-step explanation:

The quadratic equation is:

y = (x - 2)^2 - 3

So the correct option is A.

The graph clearly is the graph of a quadratic equation, there we can see that:

The y-intercept is y = 1.

The vertex is (2, -3)

Remember that if we know that a quadratic equation has a vertex (h, k), then the equation can be written as:

y = a*(x - h)^2 + k

In this case, the vertex is (2, -3), replacing that we get:

y = a*(x - 2)^2 - 3

Now, we can find the value of a, the leading coefficient, by using the fact that the y-intercept is y = 1, evaluating in zero we should get:

1 = a*(0 - 2)^2 - 3

1 = a*4 - 3

1 + 3 = a*4

4/4 = a = 1

Then we conclude that the quadratic equation is:

y = (x - 2)^2 - 3

So the correct option is A.

The sales price of the item is $48.

The sale price of an item that costs 60% of its original price which is $80 is $48. The original price of the item is $80, and it costs 60% of the original price. The amount of money we'll be spending is calculated as follows: 60 per cent of $80 (60/100) × $80= $48 Therefore, the sales price is $48. The percentage discount for the item is calculated as follows:$80 - $48 = $32

$32 is the amount of money saved due to the discount, which is then divided by the original price, $32/$80 = 0.4 or 40%. Thus, there was a 40% discount on the original price.

Jessica made $40,000 in taxable income last year and the income tax rate is 15% for the first $9000 plus 17% for the amount over $9000.

We need to determine how much must Jessica pay in income tax for last year.

Solution: Firstly, we need to calculate the amount that Jessica will pay for the first $9000 of her income using the formula; Amount = Rate x Base Rate = 15%Base = $9000Amount = 0.15 x $9000Amount = $1350Jessica will pay $1350 in taxes for the first $9000 of her income.

Answer:

Mean(m) = 462,536

sd = 29,268.29

Step-by-step explanation:

Given the following:

P(sales > 470,000) = 40% = 0.4

P(sales > 500,000) = 10% = 0.1

Using the z - table, we can locate the corresponding P values

Z = 1 - p = 1 - 0.4 = 0.6; 1 - 0.1 = 0.9

Locating the closest value to 0.6 on the z table ;

(0.25 + 0.26) / 2 = 0.255

Locating the closest value to 0.9 on the z table ;

Z = 1.28

Recall;

z =( x - m) / sd

Where m = mean ; sd = standard deviation

First condition:

0.255 = (470,000 - m) / sd

0.255 × sd = (470,000 - m) - - - - - (1)

1.28 = (500,000 - m) / sd

1.28 × sd = (500,000 - m) - - - - (2)

We can solve for one of the unknowns y subtracting equation (1) FROM 2

1.28sd - 0.255sd = (500,000 - m) - (470000 - m)

1.025sd =500,000 - m - 470000 + m

1.025sd = 30,000

sd = 29,268.29

Substituting the value od SD into (1) or (2)

1.28 × 29,268.29 = 500000 - m

37463.41 = 50000 - m

m = 50000 - 37463.41

Mean(m) = 462,536
