Answer:y = -2x + 5

Step-by-step explanation: Slope intercept form is given by the equation y = mx+b where m is the slope and b is the y intercept

1. The slope or m would be -2 because the slope of the live given is -2. We can tell since we can do rise/run or Δy/Δx.  We can take two points on the line and use Δy/Δx

Lets use:

(0,4) and (2,0)

Then plug it in so:

[tex]\frac{y2-y1}{x2-x1}[/tex]

[tex]\frac{4-0}{0-2}[/tex]

m = -2

Now we just need b which is fortunatly given to us since b is when x is equal to 0 and it saids in the question "passes through the point (0,5)" so since its (x,y) and x is 0, b is 5.

Finally, after substitution, we get:

y = -2x + 5

The x- intercept of  y = x²-4x-2 is 4.44949 and −0.44949.

The line's point of intersection with the coordinate axes is known as an intercept. The y coordinate of the intersection point is zero if the line contacts the X axis, and the intercept is known as the x intercept.

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.

Given:

To find the x-intercepts of the function, y = x²-4x-2, we need to make the y-value of the function equal to zero,

So, x²-4x-2 = 0

Now, solving the above Quadratic Equation

x²-4x-2 = 0

D = √(-4)² - 4(1)(-2)

D = √16 + 8

D = √24

D = 2√6

So, x= 4 ±  2√6/ 2

x = 4 +  2√6/2  or x = 4-  2√6/2

x = 2 + √6 or x = 2- √6

x = 4.44949 or x = −0.44949

The quantity supplied is determined by production costs, and the quantity demanded is determined by the desire for the product

The quantity demanded is a term that is used in economics to describe the total amount of a good or service that consumers demand over a given interval of time

When the production increase, fewer people could afford to put up the capital to do it, which reduce the quantity supplied to the market.

When the desire for a product increased, the amount of demand for a product will be the same since there is a larger amount of consumers who might be willing to obtain the product even at a higher price.

Answer:

54 square feet

Step-by-step explanation:

First get the area of both rectangles.

The bigger one is 8 by 9

8 times 9 is 72

the smaller one is 3 times 6 which is 18

Now you subtract both of them

72-18 = 54

The variance of the difference of two independent random variables is equal to the sum of the variances, not the difference.

False. So, var(x - z) = var(x) + var(z).

False. If x ~ n(0,0°), then z = 2x ~ n(0,2°), not n(0,4°). This is because the variance of the difference of two variables is the sum of the variance of the individual variables plus twice the covariance between the two variables. Since x and z are independent, the covariance between them is 0, and so the variance of x - z is equal to the sum of the variances of x and z.

If x ~ n(0,0°), then z = 2x ~ n(0,2°). This is because the mean of a random variable multiplied by a constant is equal to the original mean multiplied by the same constant, and the variance of a random variable multiplied by a constant is equal to the square of the constant multiplied by the original variance. So, if x has mean 0 and variance 0°, then z has mean 0 and variance 2°.

The probability of a core of the two odd number be 1/4.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

The outcome of one die has no bearing on the outcome of the other since the two dice are independent.

In this instance, a complex event's probability is calculated by adding its component simple event probabilities.

Three odd and three even results occur from each roll of the dice. So, the probability of getting an odd number exists [tex]$\frac{3}{6}=\frac{1}{2}$[/tex]

The probability that this happens with both dice exists [tex]$\frac{1}{2} \cdot \frac{1}{2}=\frac{1}{4}$[/tex]

It is relatively simple to list the "excellent" possibilities in this situation because there are a total of 36 outcomes (all numbers from 1 to 6 for one die and the same for the other die). The positive results are

(1, 1), (1, 3), (1, 5)

Answer: h= -4

Step-by-step explanation:

To solve the equation 2(h+3.5)=-1, we can use the following steps:

Distribute the 2 on the left side of the equation: 2h + 7 = -1

Subtract 7 from both sides of the equation: 2h = -8

Divide both sides of the equation by 2: h = -4

Therefore, the solution to the equation is h = -4

Answer:

x = 3.  y = 11

Step-by-step explanation:

The two equations are two simultaneous equations, which can be solved by substitution, elimination or graphical method.

Elimination method:

The coefficients of 'x’ or ‘y’ need to be the same with opposite signs. The coefficients of ‘y’ will be focused:

                  (17x - y = 40) Multiplied by 4

                  (2x + 4y = 50) Multiplied by 1

                  68x - 4y = 160

                   2x + 4y = 50

In the net total, the ‘y’ terms will cancel each other out:

                 70x = 210

                     x = [tex]\frac{210}{70}[/tex]

                     x = 3

The calculated value of x is substituted in any of the equations to determine the value of y:

                 17(3) - y = 40

                    51  - y = 40

                   51 - y - 40 = 0

                   51 - 40 - y = 0

                   11 - y = 0

                   y = 11

The average monthly pay for 150 employees was Rs 22500; however, after two employees' salaries were incorrectly inputted, the actual average monthly pay for employees was Rs 22532.

150 x 22,500 equals the total salary before correction, or Rs.

After rectification, the total salary equals

(150-2)*22500 + 25760 + 18590, or Rs. 339060.

Correct mean pay is equal to Rs. 339060 / 150, or Rs. 22532.

Initial reports stated that the mean wage for 150 workers was Rs. 22500 per month. Further examination revealed, however, that two employees' salary had been put incorrectly as Rs 25760 and Rs 19590, respectively. The two employees' actual pay were Rs. 27760 and Rs. 18590. The total salary before rectification was therefore 150*22,500, or Rs. 337,000. After two employees' pay were adjusted, the total salary was (150-2)*22500.The average monthly pay for 150 employees was Rs 22500; however, after two employees' salaries were incorrectly inputted, the actual average monthly pay for employees was Rs 22532 (150-2)*22500 + 25760 + 18590 = Rs339060. Consequently, it was determined that Rs339060 / 150 = Rs22532 was the proper mean wage paid to employees. After correcting the two incorrectly reported salaries, the average monthly wage for the organization's employees came to Rs22532.

The vertex of a quadratic equation is the minimum or maximum point of the equation.

Given that, the quadratic function f(x) has a vertex at (1, 6) and opens downward and g(x) = (x - 7)² + 1,

The vertex of f(x) is at (1, 6), we know that a vertical line passing through the vertex is called the axis of symmetry for the parabola.

That mean, axis of symmetry will pass through (1, 6)

Therefore, the axis of symmetry for f(x) is x = 1

And, g(x) = (x - 7)² + 1

= x²+49-14x+1

= x²-14x+50

Vertex = -b / 2a

here, b = -14 and a = 1

Vertex (h, k) = 14 / 2 = 7

To find k, put x = 7 in the equation,

(7-7)²+1 = 1

Therefore, point of the vertex = (7, 1)

That mean axis of the symmetry will pass through (7, 1)

Therefore, axis of the symmetry for g(x) = 7

A:  The z-score is -0.9375; B:  a z-score of 1.25 corresponds to a score of 750; C: a score of 550 is one standard deviation below the mean.

a) To find the standardized z-score for a student scoring 595 on their GMAT, we use the formula:

z = (x - mu) / sigma

where x is the student's score, mu is the mean, and sigma is the standard deviation. In this case, mu = 630 and sigma = 80, so we have:

z = (595 - 630) / 80 = -0.9375

Therefore, the z-score is -0.9375.

b) To find the number of standard deviations a student scoring 670 is from the mean, we use the formula:

z = (x - mu) / sigma

where x is the student's score, mu is the mean, and sigma is the standard deviation. In this case, mu = 630 and sigma = 80, so we have:

z = (670 - 630) / 80 = 0.75

Therefore, the student scoring 670 is 0.75 standard deviations from the mean.

c) To find the score that corresponds to a z-score of 1.25, we use the formula:

x = mu + z * sigma

where x is the student's score, mu is the mean, and sigma is the standard deviation. In this case, mu = 630 and sigma = 80, so we have:

x = 630 + 1.25 * 80 = 750

Therefore, a z-score of 1.25 corresponds to a score of 750.

d) To find the score that is one standard deviation below the mean, we use the formula:

x = mu - sigma

where x is the student's score, mu is the mean, and sigma is the standard deviation. In this case, mu = 630 and sigma = 80, so we have:

x = 630 - 80 = 550

Therefore, a score of 550 is one standard deviation below the mean.
