If circle with center N with m∠MNP=124 ∘ and MN=13,  the area of sector MNP is approximately equal to 194.86 square units.

To find the area of a sector of a circle, we need to use the formula:

Area of sector = (central angle/360°) x πr²

Where r is the radius of the circle.

In this problem, we know that the central angle m∠MNP is 124° and MN, which is also the radius of the circle, is 13. So we can substitute these values into the formula:

Area of sector = (124/360) x π(13)²

Area of sector ≈ 194.86

Therefore, the area of sector MNP is approximately equal to 194.86 square units.

Here's how to do it:-

First write down what's given:-

y -7.2 = 8

Next, we do like this:-

y = 8+ 7.2

We transferred 7.2 to the other side of the ' = ' sign.

When we do so, the sign of the number changes

Here 7.2 was negative first but when we transferred it to the other side, its sign changed to positive.

So,

y = 8 + 7.2

Now, just add it!

8 + 7.2 equals 15.2

Find the given attachments

Using the absolute value function, we have that:

The absolute function is defined by:

It measures the distance of a point x to the origin.

For the batch, the weights are given as follows:

0.58, 0.63, 0.65, 0.53, 0.61.

Hence the mean is:

(0.58 + 0.63 + 0.65 + 0.53 + 0.61)/5 = 0.6.

Weights that are more than 0.06 of the pounds must be thrown out, hence the inequality for the valid weights is given by:

|x - 0.6| ≤ 0.06.

Hence the range of valid weighs is:

0.53 is not in the interval, hence the gasket with a weight of 0.53 lb should be thrown out.

The length of the fence around the enclosure not including the gates is:2l + 2w + 8 m

To find the length of the fence around the enclosure, we need to first find the perimeter of the rectangle and then subtract the combined length of the two gates from it.

Let's assume the length of the rectangle is 'l' and the width is 'w'.

From the given data, we know that each gate is 4 m wide.

Therefore, the width of the rectangle is:

Width = w + (4 m + 4 m) = w + 8 m

The perimeter of the rectangle is:

P = 2l + 2(w + 8 m) = 2l + 2w + 16 m

Now, we need to subtract the combined length of the two gates from the perimeter:

P - 2 × 4 m = 2l + 2w + 16 m - 8 m = 2l + 2w + 8 m

So, the length of the fence around the enclosure not including the gates is:2l + 2w + 8 m

The probability that a randomly selected student will like pizza but not chicken nuggets is (28n - 8)/(28n + 7), where 28n is the students who like pizza and 8 is students who like both pizza and chicken nuggets.

To find the probability that a randomly selected student will like pizza but not chicken nuggets.

Let P = the number of students who like pizza but not chicken nuggets

Then, P = the number of students who like pizza - the number of students who like both pizza and chicken nuggets

P = 28n - 8

So, the probability that a randomly selected student will like pizza but not chicken nuggets is:

P(Pizza but not nuggets) = P/(Total number of students)

We can find the total number of students who like either pizza or chicken nuggets by adding the number of students who like pizza and the number of students who like chicken nuggets, and then subtracting the number of students who like both:

Total number of students = 28n + 15 - 8 = 28n + 7

So, the probability that a randomly selected student will like pizza but not chicken nuggets is:

P(Pizza but not nuggets) = P/(Total number of students) = (28n - 8)/(28n + 7)

Answer:

The minimum exam score to be awarded an A is about 8.52.

Step-by-step explanation:

Let X represent the scores on a common final exam.

It is provided that X follows a normal distribution with mean, μ = 71 and standard deviation, σ = 9.

It is provided that according to the department policy is that the top 10% of students receive an A.

That is, P (X > x) = 0.10.

⇒ P (X < x) = 0.90

⇒ P (Z < z) = 0.90

The corresponding z-score is:

z = 1.28

Compute the value of x as follows:

\(z=\frac{x-\mu}{\sigma}\\\\1.28=\frac{x-71}{9}\\\\x=71+(1.28\times 9)\\\\x=82.52\)

Thus, the minimum exam score to be awarded an A is about 8.52.

The weight of a 35.01-carat diamond in grams and ounces

Information given in the question include

1 carat = 0.2 gram,

1 carat = 3.086 grains,

1 ounce = 437.5 grains.

The conversion of the weight units using the given variables can bbe done as follows

1 carat = 0.2 gram

35.01-carat diamond = ?

cross multiplying gives

1 * ? = 35.01 * 0.2

? = 7.002gram

1 carat = 3.086 grains

35.01-carat diamond = ?

cross multiplying gives

1 * ? = 35.01 * 3.086

? = 108.041 grains

That is 35.01-carat diamond = 108.041 grains

1 ounce = 437.5 grains

? = 108.041 grains

cross multiplying gives

437.5 * ? = 108.041 * 1

? = 108.041 /437.5

? = 0.247 ounces

We cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.

The mean is a measure of central tendency that represents the average value of a set of numbers. It is also called the arithmetic mean or simply the average.

We cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.

The mean and the median are two different measures of central tendency, and they can have different values depending on the distribution of the data. In general, if a data set is symmetric and bell-shaped, the mean and the median are close to each other. However, if the data set is skewed, the mean and the median may be different.

For example, consider the following two data sets:

Set 1 data: 1, 2, 3, 4, and 5.

The median is 3.

The mean is (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3.

Data set 2: 1, 2, 3, 4, 10

The median is 3.

The mean is (1 + 2 + 3 + 4 + 10) / 5 = 20 / 5 = 4.

In data set 1, the mean is the same as the median. In data set 2, the mean is greater than the median because the value 10 is an outlier that pulls the mean up.

Therefore, without additional information about the distribution of the data, we cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.

Step-by-step explanation:

Vertical angles are equal   r = 70 degrees

In the function given, the type of discontinuity that exists at x = -3 when b is not equal to 11/6 is a jump discontinuity.

For the function f(x) to be continuous at x = -3, the limit of f(x) as x approaches -3 from both the left and the right must be equal to f(-3). That is:

lim x→-3+ f(x) = f(-3) = lim x→-3- f(x)

Since x < -3 for the second part of the function, we can calculate the left-hand limit as:

lim x→-3- f(x) = -3(-3)² + 5(-3) + 4b(-3) = 9 + (-15) - 12b = -6 - 12b

And the right-hand limit as:

lim x→-3+ f(x) = 3(-3)² - 2b(-3) = 27 + 6b

Therefore, we must have:

-6 - 12b = 27 + 6b

Solving for b, we get:

b = 33/18 = 11/6

So when b = 11/6, the function is continuous at x = -3.

Now let's consider the case where b is not equal to 11/6. In this case, the left-hand limit and right-hand limit are not equal, which means the function has a jump discontinuity at x = -3. The value of the function at x = -3 from the left-hand side is:

f(-3-) = -3(-3)² + 5(-3) + 4b(-3) = 9 - 15 - 12b = -6 - 12b

And the value of the function at x = -3 from the right-hand side is:

f(-3+) = 3(-3)² - 2b(-3) = 27 + 6b

Therefore, the type of discontinuity that exists at x = -3 when b is not equal to 11/6 is a jump discontinuity.
