The area of the rectangle is 56 square yards.

What is the area of rectangle?

The area of a rectangle is the amount of space or surface inside the shape, measured in square units. It is calculated by multiplying the length of the rectangle by its width.

The formula for the area of a rectangle is:

Area = length x width

In this case, the width is 7 yards and the length is 8 yards. Therefore, the area of the rectangle is:

Area = 7 yards x 8 yards = 56 square yards

So the area of the rectangle is 56 square yards.

Answer:

C edge 2020

Step-by-step explanation:

i got it right on the practice.

Answer:

42 + 3(n - 1)

Step-by-step explanation:

We can model this situation with an arithmetic sequence where n is the row number.

Start off with the first row. We know that there are 42 seats to begin with. Since the starting value for this sequence won't change (unless someone breaks or adds another chair), we can represent it as a constant, or a coefficient without a variable.

# of seats in the 1ˢᵗ row = 42

Then, for each row after that, there are 3 more seats added. Since the total amount of seats added since the first row varies by each row, we have to use a variable to represent this change. The variable's coefficient represents the amount of seats added per row.

# of seats in the nᵗʰ row = 42 + 3n

However, this initial attempt is incorrect, as if we test it with the first row (when n = 1), we get 42 + 3(1), which is not equal to 42. We can account for this shifting in the + 3 (because we don't want to apply it to the first row) by subtracting 1 from n:

# of seats in the nᵗʰ row = 42 + 3(n - 1)

Finally, we can check this new equation to make sure it works:

42 ≟ 42 + 3(1 - 1)

42 ≟ 42 + 3(0)

42 = 42

That is Talia's incorrect step. The incorrect step is: C. Step 3

Thus, we get:

Slope = rise/ run

Calculating the slope using two points on the line, (2, 5) and (1, 3), we have:

Slope (m) = (5 - 3)/(2 - 1)

Slope (m) = (2)/(1)

Slope (m) = 2

The probability that between 10 and 15 (inclusive) out of 40 80-year-olds will die in the next year can be calculated using the binomial probability formula. It involves summing the probabilities of each individual outcome falling within the desired range.

The probability of a single 80-year-old person dying in the next year is given as 0.27. To calculate the probability of a specific number of deaths within a range, we can use the binomial probability formula:

P(X=k) = (nCk) * p^k * (1-p)^(n-k)

Where:

- P(X=k) is the probability of exactly k successes (deaths in this case),

- n is the total number of trials (number of 80-year-olds),

- k is the desired number of successes falling within the range (between 10 and 15 inclusive),

- p is the probability of a single success (probability of death in the next year), and

- (nCk) represents the combination, which is the number of ways to choose k successes out of n trials.

We need to calculate the probabilities for each individual outcome falling within the desired range (10, 11, 12, 13, 14, 15), and then sum them to find the overall probability.

By plugging in the values into the formula and calculating the probabilities for each desired number of deaths (k) and summing them up, we can determine the probability that between 10 and 15 out of the 40 80-year-olds will die in the next year.

Using synthetic division, we can divide the polynomial x³ + 7x² - 12x + 14 by the divisor 1. Performing the synthetic division, we obtain a quotient of x² + 6x - 6 and a remainder of 8.

To divide the polynomial x³ + 7x² - 12x + 14 by the divisor 1 using synthetic division, we set up the synthetic division table as follows:

1  |   1   7  -12   14

We begin by bringing down the coefficient of the first term, which is 1, and place it on the line below the division bar. Then we multiply the divisor, 1, by the value we brought down and write the result under the next coefficient. Adding the values in the second row, we obtain the new value. We continue this process for each term until we reach the last term.

1  |   1   7  -12   14

 1   8  -4     10

The values in the last row represent the coefficients of the quotient polynomial. Therefore, the quotient is x² + 6x - 6. The remainder, which is the last value in the last row, is 10. Since the divisor is 1, the remainder does not affect the quotient. Hence, the result of the division is x² + 6x - 6 with a remainder of 10.

Answer:

C. 66.4 mph

Step-by-step explanation:

∵ The ratio of speed of motorcycle and the circumference of the tyre is constant for a motorcycle,

If x be the speed ( in mph ) of a motorcycle having the tyre of diameter 28 inches,

⇒ The ratio of speed and circumference = \frac{x}{2\pi (14)}

( Because radius = Diameter / 2 ),

While, the speed of the same motorcycle having the tyre of diameter 25 inches is 60 mph,

⇒ The ratio of speed and circumference = \frac{60}{2\pi (12.5)}

By the above statement,

\frac{x}{2\pi (14)}=\frac{60}{2\pi (12.5)}

\implies x=\frac{60\times 14}{12.5}=\frac{336}{5}=67.2\approx 67

So, the actual speed of the motorcycle after changing the tyre is 67 mph ( approx )

Hence, option 'C' is correct.

The approximations for the values of f at the given points are:

To find the linear approximation of the function f(x,y,z) = x²/(y²z²) at point (3,2,6), we need to compute the partial derivatives of f with respect to x, y, and z at that point:

fx(x,y,z) = 2x/(y²z²), so fx(3,2,6) = 2/(2² * 6²) = 1/54

fy(x,y,z) = -2x²/(\(y^3\)z²), so fy(3,2,6) = -18/64

fz(x,y,z) = -2x²/(y²\(z^3\)), so fz(3,2,6) = -2/\(6^3\) = -1/108

The linear approximation of f at point (3,2,6) is given by:

L(x,y,z) = f(3,2,6) + fx(3,2,6)(x-3) + fy(3,2,6)(y-2) + fz(3,2,6)*(z-6)

L(x,y,z) = 9/144 + (1/54)(x-3) - (18/64)(y-2) - (1/108)*(z-6)

To approximate the value of f at points (3.02, 1.97, 5.99), we can use the linear approximation L:

f(3.02, 2, 6) ≈ L(3.02, 2, 6) = 0.0878

f(1.97, 2, 6) ≈ L(1.97, 2, 6) = 0.0545

f(3, 2, 5.99) ≈ L(3, 2, 5.99) = 0.1387

Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

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

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

The chemicals under considerationm an important quantity is the total proportion Y1 +Y2 found in any sample.V(Y1 + Y2) = Var(Y1) + Var(Y2) + 2Cov(Y1, Y2) = 1/18 + 1/18 + 2(1/144) = 5/72.

To find E(Y1 + Y2), we first find the marginal distribution of Y1 and Y2 by integrating the joint density function over the other variable as follows:

f1(y1) = ∫f(y1,y2)dy2 = ∫2dy2 from 0 to 1-y1 = 2(1-y1) for 0 ≤ y1 ≤ 1

f2(y2) = ∫f(y1,y2)dy1 = ∫2dy1 from 0 to 1-y2 = 2(1-y2) for 0 ≤ y2 ≤ 1

Now we can find E(Y1 + Y2) as follows:

E(Y1 + Y2) = ∫∫(y1 + y2)f(y1,y2)dy1dy2

= ∫∫(y1 + y2)2dy1dy2 over the region 0 ≤ y1 ≤ 1-y2, 0 ≤ y2 ≤ 1

E(Y1 + Y2) = ∫0^1∫0^(1-y1) (y1 + y2)2dy2dy1

= ∫0^1[y1(y1/2 + 2/3) + 1/3]dy1

= 7/12

To find V(Y1 + Y2), we can use the fact that V(Y1 + Y2) = V(Y1) + V(Y2) + 2Cov(Y1, Y2), where Cov(Y1, Y2) is the covariance of Y1 and Y2. First, we need to find the variances of Y1 and Y2:

Var(Y1) = E(Y1^2) - [E(Y1)]^2 = ∫∫y1^22dy1dy2 - [∫∫y1f(y1,y2)dy1dy2]^2

= ∫0^1∫0^(1-y1) y1^22dy2dy1 - [∫0^1(2y1-2y1^2)dy1]^2

= 1/18

Var(Y2) = E(Y2^2) - [E(Y2)]^2 = ∫∫y2^22dy1dy2 - [∫∫y2f(y1,y2)dy1dy2]^2

= ∫0^1∫0^(1-y2) y2^22dy1dy2 - [∫0^1(2y2-2y2^2)dy2]^2

= 1/18

Now we need to find the covariance of Y1 and Y2:

Cov(Y1, Y2) = E(Y1Y2) - E(Y1)E(Y2) = ∫∫y1y2f(y1,y2)dy1dy2 - (∫∫y1f(y1,y2)dy1dy2)(∫∫y2f(y1,y2)dy1dy2)

= ∫0^1∫0^(1-y1) 2y1y2dy2dy1 - (7/12)(7/12)

= 1/144

Therefore, V(Y1 + Y2) = Var(Y1) + Var(Y2) + 2Cov(Y1, Y2) = 1/18 + 1/18 + 2(1/144) = 5/72.
