Evaluate x Square-4x for x=-7

Answer:

y = 6x+9

Step-by-step explanation:

Equations that are parallel have the same slope

y = 6x+7 is written in slope intercept form where the slope is 6 and the y intercept is 7

The lines will have a slope of 6

The point (0,9) is the y intercept because the x value is 0

We can write the equation in slope intercept form y = mx+b

y = 6x+9

Answer:

Hello! The answer is y = 6x + 9.

Step-by-step explanation:

When lines are parallel, they will have the same slope but a different y-intercept.

The y-intercept, in this case, would be (0, 9) since the x-coordinate equals 0. This leaves us with 9 as the y-intercept.

Our slope-intercept form equation will be written as:

y = 6x + 9

Answer: The second candle can burn for 20 hours before its length is zero inches.

Step-by-step explanation:

If the second candle is 8 inches in length and burns down at a rate of 2/5 inches per hour, we can use a simple formula to find how long it can burn before its length is zero inches:

Number of hours = Length ÷ Rate of burn

Number of hours = 8 inches ÷ (2/5 inches per hour)

Number of hours = 8 inches × (5/2) hours per inch

Number of hours = 20 hours

Therefore, the second candle can burn for 20 hours before its length is zero inches.

The speed of P when t = 3 seconds is  95.00 m/s

We can find the speed by finding the net force acting on the particle P. Let F_net be the net force acting on P, then we have:

F_net = F₁ + F₂

where:

F₁ = (-i + 2j)N

F₂ = the direction of the vector (i + j).

Let's find the magnitude and direction of F₂. We know that F_net is in the direction of the vector (i + 3j), so we can write:

F_net = F₂ + k(i + 3j)

where:

k = some constant. Since F₂ is in the direction of (i + j), we can write:

F₂ = a(i + j)

where:

a = constant.

Substituting the into the equation for F_net:

F_net = a(i + j) + k(i + 3j)

To find the values of a and k, we use the acceleration of P which is (31 + 9j) m/s². The net force on P is:

F_net = m*a

where m = the mass of P.

Equating the two expressions for F_net:

a(i + j) + k(i + 3j) = m(31 + 9j)

Expanding both sides:

(ai + aj) + (ki + 3kj) = 31m + 9mj

Equating the coefficients of i and j, we get two equations:

a + k = 31m (1)

a + 3k = 9m (2)

Solving these equations:

a = 9m

k = 22m

Substituting these values back into the expression for F_net, we have:

F_net = 9m(i + j) + 22m(i + 3j) = 31mi + 69mj

Now, we can use the equation for acceleration to find the mass of P:

F_net = m*a

31mi + 69mj = m(31 + 9j)

m = 31 / (31 + 9j) = 31 / (31 - 9i)

Next, we shall use the initial velocity and acceleration to find the velocity of P after 3 seconds.

Let v(t) be the velocity of P at time t, then:

v(t) = v(0) + a*t

where v(0) = 3i - 22j and

a = (31 + 9j) m/s²

Substituting t = 3 seconds:

v(3) = (3i - 22j) + (31 + 9j)(3)

= 96i - 1j

Therefore, the speed of P at t = 3 seconds is the magnitude of v(3):

v(3)| = (\(\sqrt{96^{2} }\) + (-1)²) = \(\sqrt9217\) = 95.00 m/s

The statements supported by the data in the table are:

The mean number of cars sold in a month is the same at both dealerships.

The total number of cars sold is the same at both dealerships.

The data for Admiral Autos shows greater variability.

To determine which statements are supported by the data in the table, let's analyze the given information:

The mean number of cars sold in a month is the same at both dealerships.

To calculate the mean, we need to find the average number of cars sold each month at each dealership.

For Admiral Autos:

(4 + 19 + 15 + 10 + 17) / 5 = 65 / 5 = 13

For Countywide Cars:

(9 + 17 + 14 + 10 + 15) / 5 = 65 / 5 = 13

Since both dealerships have an average of 13 cars sold per month, the statement is supported.

The median number of cars sold in a month is the same at both dealerships.

To find the median, we arrange the numbers in ascending order and select the middle value.

For Admiral Autos: 4, 10, 15, 17, 19

Median = 15

For Countywide Cars: 9, 10, 14, 15, 17

Median = 14

Since the medians are different (15 for Admiral Autos and 14 for Countywide Cars), the statement is not supported.

The total number of cars sold is the same at both dealerships.

To find the total number of cars sold, we sum up the values for each dealership.

For Admiral Autos: 4 + 19 + 15 + 10 + 17 = 65

For Countywide Cars: 9 + 17 + 14 + 10 + 15 = 65

Since both dealerships sold a total of 65 cars, the statement is supported.

The range of the number of cars sold is the same for both dealerships.

The range is determined by subtracting the lowest value from the highest value.

For Admiral Autos: 19 - 4 = 15

For Countywide Cars: 17 - 9 = 8

Since the ranges are different (15 for Admiral Autos and 8 for Countywide Cars), the statement is not supported.

The data for Admiral Autos shows greater variability.

To determine the variability, we can look at the range or consider the differences between each data point and the mean.

As we saw earlier, the range for Admiral Autos is 15, while for Countywide Cars, it is 8. Additionally, the data points for Admiral Autos are more spread out, with larger differences from the mean compared to Countywide Cars. Therefore, the statement is supported.

Based on the analysis, the statements supported by the data are:

The mean number of cars sold in a month is the same at both dealerships.

The total number of cars sold is the same at both dealerships.

The data for Admiral Autos shows greater variability.

Given:

Mean,

\(\mu = 300,000\)

Standard deviation,

\(\sigma = 50,000\)

The Chebyshev theorem will be used for the solution of the given query,

i.e., \(P(|X - \mu| < k \sigma ) \geq 1-\frac{1}{k^2}\)

(i)

⇒ \(1-\frac{1}{k^2} = 0.75\)

            \(k = 2\)

The lower limit will be:

= \(\mu - k \sigma\)

= \(300000-2\times 50000\)

= \(200000\)

The upper limit will be:

= \(\mu + k \sigma\)

= \(300000+2\times 50000\)

= \(400000\)

hence,

The 75% houses sold are between:

⇒ (200000, 400000)

(ii)

⇒ \(\mu -k \sigma = Lower \ limit\)

By putting the values, we get

   \(300000-50000k = 150000\)

   \(300000-150000=50000k\)

                  \(150000=50000k\)

                           \(k=\frac{150000}{50000}\)

                              \(=3\)

now,

⇒ \(1-\frac{1}{k^2} = 1-\frac{1}{3^2}\)

              \(=\frac{8}{9}\)

              \(=0.8888\)

              \(=88.88\) (%)

hence,

88.88% houses sold between 150000 and 450000.      

(iii)

⇒ \(\mu - k \sigma = Lower \ limit\)

By putting the values, we get

   \(300000-50000k = 170000\)

   \(300000-170000=50000 k\)

                  \(130000= 50000 k\)

                          \(k = \frac{130000}{50000}\)

                             \(=2.6\)

now,

⇒ \(1-\frac{1}{k^2} = 1-\frac{1}{2.6^2}\)

              \(=0.8521\)

              \(=85.21\) (%)

hence,

The probability of Event A is 1/360 and the probability of Event B is 1/15.

For Event A, we can calculate the probability by considering the order in which the acts are scheduled.

There are 6 acts, so there are 6 possible choices for the first act. After the first act is scheduled, there are 5 remaining acts, so there are 5 possible choices for the second act.

Similarly, there are 4 possible choices for the third act, and 3 possible choices for the fourth act.

Finally, there are 2 possible choices for the fifth act, and only 1 choice remains for the last act.

Therefore, the total number of possible ways to schedule all 6 acts is:

6 x 5 x 4 x 3 x 2 x 1 = 720

Since we are only interested in one specific order of the first four acts, we need to count the number of ways to schedule the remaining two acts after the first four have been scheduled in the desired order.

There are 2 remaining acts, so there are 2 possible choices for the fifth act.

Only one act remains for the last slot.

Therefore, the total number of ways to schedule all 6 acts such that the acrobat is first, the singer is second, the violinist is third, and the whistler is fourth is:

1 x 1 x 1 x 1 x 2 x 1 = 2

Thus, the probability of Event A is:

P(A) = 2/720 = 1/360

For Event B, we want to count the number of ways to schedule the first four acts as the whistler, the acrobat, the guitarist, and the dancer, in any order.

There are 4 acts, so there are 4 possible choices for the first act. After the first act is scheduled, there are 3 remaining acts, so there are 3 possible choices for the second act.

Similarly, there are 2 possible choices for the third act, and only one choice remains for the fourth act.

Therefore, the total number of possible ways to schedule the first four acts is:

4 x 3 x 2 x 1 = 24

Since we do not care about the order in which the last two acts are scheduled, we can simply choose any two acts from the remaining 2. There are 2 ways to do this.

Therefore, the total number of ways to schedule all 6 acts such that the first four acts are the whistler, the acrobat, the guitarist, and the dancer, in any order is:

24 x 2 = 48

Thus, the probability of Event B is:

P(B) = 48/720 = 1/15

Therefore, the equation of the line that fits the given data points and goes through the red open point is approximately y = -0.0143x + 44.545.

In mathematics, slope is a measure of the steepness of a line. It is the ratio of the vertical change (rise) between two points on a line to the corresponding horizontal change (run) between those points. The slope of a line can be calculated by dividing the change in the y-coordinate of two points on the line by the change in the x-coordinate of those same points.

Here,

To find the slope of a line that fits the data points (1150,28) and (1500,23), we can use the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the two points.

Substituting the given values, we get:

slope = (23 - 28) / (1500 - 1150) = -5 / 350 = -0.0143 (rounded to 4 decimal places)

Therefore, the slope of the line that fits the given data points is approximately -0.0143. To fit the line to the red open point, we need to find the y-intercept of the line using the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where (x1, y1) is the point (1150,28) and m is the slope we just calculated.

Substituting the values, we get:

y - 28 = -0.0143(x - 1150)
