The simplified expression for the perimeter of the rectangle is 10x + 4.

Perimeter of a straight sided figures or objects is the total length of it's boundary.

It is defined for, squares, rectangles, triangles and other polygons.

Given is a rectangle.

Length of the rectangle = 3x + 6

Width of the rectangle = 2x - 4

The formula to calculate the perimeter of the rectangle is,

Perimeter of a rectangle = 2 (Length + Width)

                                         = 2 (3x + 6 + 2x - 4)

                                         = 2 (5x + 2)

                                         = 10x + 4

Hence the perimeter of the rectangle is 10x + 4 units.

Step-by-step explanation:

Based on the given information, we conducted a random experiment to compare the mean time to recovery between a newly formulated drug and the standard drug. The mean time to recovery for the standard drug is known to be 26 days.

After an extensive random experiment involving 65 patients, we constructed a 95% confidence interval estimate for the mean recovery time for patients on the new drug, which was found to be (24.6, 27.8) days.

Based on this information, we can conclude that the mean recovery time for patients on the new drug is significantly different from the mean recovery time for patients on the standard drug. Since the confidence interval for the new drug does not include the mean recovery time of the standard drug (26 days), it suggests that the new drug produces a different effect on the mean time to recovery compared to the standard drug.

Answer:

The answer is A

If \(MU_{x}/P_{x}\)=30 and \(MU_{y} /P_{y}\)=40 then the consumer should buy the commodity y to maximise utility.

Given that \(MU_{x}/P_{x}\)=30 and \(MU_{y} /P_{y}\)=40 of commodities x and y.

Marginal utility is the additional utility that a consumer gets from consuming additional units of commodity. For maximising the utility of the consumer,the ratio of marginal utilities must be equal to the ratio of the products.

There can be two situations in our case:

Because \(MU_{x}/P_{x}\)<\(MU_{y} /P_{y}\)

So to equalise the ratio we need to reduce \(MU_{y} /P_{y}\). To reduce the utility of y the consumer needs to increase the consumption of y because as the consumption of commodity y increase it decreases the utility of commodity y.

Hence if \(MU_{x}/P_{x}\)=30 and \(MU_{y} /P_{y}\)=40 then the consumer should buy the commodity y to maximise utility.

The probability of choosing sausage and onion by Rosa's mom from the given 8 different toppings as per given condition is equal to

(1/ ⁸C₂).

As given in the question,

Total number of different toppings = 8

Number of different toppings choose by Rosa's mom randomly = 2

Possibility of choosing sausage and onion (any one) = 1

Total number of outcomes = ⁸C₂

Number of favorable outcomes = 1

Probability of choosing sausage and onion ( exactly ) one topping

= ( Number of favorable outcomes ) / ( Total number of outcomes )

= ( 1/⁸C₂ )

Therefore, the probability when Rosa's mom chooses sausage and onion out of 8 toppings is equal to ( 1/⁸C₂ ).

The above question is incomplete, the complete question is:

The reasonableness of the estimate depends on the quality and reliability of the data sources and methodology used to arrive at the estimate.

In order to determine whether 12% is a reasonable estimate of the proportion of all Americans who eat chocolate

frequently, we would need to define what is meant by "frequently."

If we define "frequently" as "at least once a week," then 12% may or may not be a reasonable estimate, depending on

the data source and methodology used to arrive at that estimate.

For example, if the estimate is based on a small sample size or a non-representative sample of the population, then it

may not be a reliable estimate of the true proportion of Americans who eat chocolate frequently. Additionally, if the

estimate is several years old, it may not accurately reflect current trends and habits.

On the other hand, if the estimate is based on a large, nationally representative sample of the population, and is

relatively recent, then 12% could be a reasonable estimate of the proportion of Americans who eat chocolate

frequently.

Answer:

The slope of the line show is always writen in the form of rise/ run or y/x. Bassically the answer should look like a fraction. In this case, the slope of the line is 1/2. Graphing points on the line always make this process eaiser. From one point to another measure the rise/run or y/x and that will be your slope. Here the line rises one point and runs 2. The slope of the line is positive because it slants right in quadrant one of the graph.

The rise and run that would give us a similar right triangle on the same given line is: B. a rise of 8 and a run of 6.

The rise/run of any two points on the same line are have the same slope value.

Given the coordinates:

The rise of triangle ABC = change in y = 4 units

The run of triangle ABC = change in x = 3 units

Rise/run = 4/3

Therefore, a rise of 8 and a run of  6 would give us: 8/6 = 4/3.

Step-by-step explanation:

In order to find the small standard error, there is always need of a complete set which is called the large sample.

If tried to do a small or repeating sample, you will most likely not get an error and you could get a repetition. If you do a population sample, you wont get accurate results at all.

The volume of the cylinder is given by:

V = π * h * (R^2 - r^2)

where h is the height of the cylinder, R is the radius of the larger circle, and r is the radius of the smaller circle.

In this case, h = 1, R = 7 + cos(θ), and r = 7. We can simplify the formula as follows:

where h is the height of the cylinder,

R is the radius of the larger circle,

r is the radius of the smaller circle.

V = π * (7 + cos(θ))^2 - 7^2

We can now evaluate the integral at θ = 0 and θ = 2π. When θ = 0, the integral is equal to 0. When θ = 2π, the integral is equal to 154π.

Therefore, the value of the volume is 154π.

Answer:

m∠2 = 16°

Step-by-step explanation:

m∠1 + m∠2 = 90°

(Complementary angles)

74° + m∠2 = 90°

m∠2 = 90° - 74°

m∠2 = 16°

The measure of the angles 2 is 16 degrees

complementary angles sum up to 90 degrees.

Given one of the angles to be 74 degrees, hence;

m<1 + m<2 = 90 degrees

74 + m<2 = 90

m<2 = 90 - 74

m<2 = 16 degrees

Step-by-step explanation:

Let the interest rate be x100

So we have for simple interest: x100×$2600=$390

This is the same as: ddddddddddx×$2600100=$390

x×$2600100=$390

Divide both sides by $26.

x×$26$26=$390$26

x×1=$390$26

x=15

But x is from x100

The % symbol is like a unit of measurement and one that is worth 1100

To find the measure of angle R in triangle QRS, we can use the fact that the sum of the angles in a triangle is 180 degrees.

Given:

Q = 8x

m/R = 14x + 2 degrees

m/S = 10x + 50 degrees

The sum of angles Q, R, and S is 180 degrees:

Q + R + S = 180

Substituting the given values:

8x + (14x + 2) + (10x + 50) = 180

Simplifying the equation:

8x + 14x + 2 + 10x + 50 = 180

32x + 52 = 180

32x = 180 - 52

32x = 128

x = 128/32

x = 4

Now that we have the value of x, we can substitute it back into the given expressions to find the measures of angles Q, R, and S.

Q = 8x = 8 * 4 = 32 degrees

m/R = 14x + 2 = 14 * 4 + 2 = 58 degrees

m/S = 10x + 50 = 10 * 4 + 50 = 90 degrees

Therefore, the measure of angle R is 58 degrees. So, the correct answer is C. 58°.

Step-by-step explanation:

Sandi can run 348 cm in a second. Let's find out how many cm she can run in a minute: in a minute there are 60 seconds. So lets multiply 348cm times 60, this gives you 20,880. That is how much she travels in a minute, now let's find out how much she runs in an hour: if she runs 20,880 cm in an minute and there are 60 minutes in an hour, then all you have to do is multiply 20,880 times 60, this gives you 1,252,800. That is how many cm she runs in an hour. Now let's change from cm to miles. There are 160,934 cm in a mile. If we divide 1,252,800 by 160,934 this will give you
