Answer 1

-7^2 = -(7 x 7) = -49

---Because the negative is on the outside and there are no parenthesis, the product will be negative

-49 - - 1 = -49 + 1 = -48

---Subtracting a negative is the same thing as adding a positive!

Answer: -48

The base of a solid is bounded by x^2 + y^2 = 16. Cross sections perpendicular to the x-axis are right isosceles triangles with one leg located in the base. Which definite integral represents the volume of this solid?

Answers

The equation for the base is that of a circle, so the cross sections will have a leg of length equal to the vertical distance between its halves.

x² + y² = 16 ⇒ y = ±√(16 - x²)

⇒ length = √(16 - x²) - (-√(16 - x²)) = 2 √(16 - x²)

Cross sections with thickness ∆x have a volume of

1/2 length² ∆x = 1/2 (2 √(16 - x²))² ∆x = (32 - 2x²) ∆x

since they are isosceles triangles and so their bases and heights are equal.

Then the total volume would be (D)

[tex]\displaystyle \int_{-4}^4 \frac12 \left(2 \sqrt{16-x^2}\right)^2 \, dx[/tex]

since the entire angle is 90 degrees, set 17x + 13 and 32 - 2x to equal 90

17x + 13 + 32 - 2x = 90
15x + 13 + 32 = 90
15x + 45 = 90
15x = 45
x = 3

to figure out what DBE is, set the x value of 17x + 13 to 3

What is the median of the data set?

Answers

Answer: 8.5 (choice B)

=========================================================

Explanation:

The diagram shows us we have this data set

{5, 8, 8, 8, 8, 9, 9, 9, 10, 10}

Cross off the outer most items (the 5 and the second 10) to get this smaller set

{8, 8, 8, 8, 9, 9, 9, 10}

Repeat the last step of crossing off the outer most items to get

{8, 8, 8, 9, 9, 9}

Keep this process going until we have this set of steps

{8, 8, 9, 9}

{8, 9}

We have two items left, which are tied for the middle, so we compute the midpoint

(8+9)/2 = 17/2 = 8.5 is the median

This is the middle most value

So the first thing to do is get the number of angles inside this pentagon, which is 540 degrees. One way to do this is that you know a pentagon is formed of 3 triangles and since there are 180 degrees in a triangle, 3x180=540

Then it is algebra

540=91+125+92+(3x-5)+(4x-8)

Simplify what you can and collect like terms

540=308+3x-5+4x-8

540=308+7x-13

Then move everything over to the one side so that the variable is isolated

Which statement is most likely to be true? the ages of the mackerels are the most dispersed from the team’s mean. the ages of the stars are the most dispersed from the team’s mean. the ages of the dolphins are the most dispersed from the team’s mean. the ages of the giants are the most dispersed from the team’s mean.

Answers

The ages of the Stars are the most dispersed from the team’s mean

Which statement is right?

Standard deviation is one way to measure the average of the data by determining the spread of the data. It actually explains how much the observation points are further away from the mean of the data.

Higher the standard deviation, higher the spread of the data and higher is the uncertainty. This means that the team with the highest standard deviation will have the most dispersion.

In this case, the standard deviation of 4.1 is the largest number, therefore, the statement "The ages of the Stars are the most dispersed from the team’s mean." is true

Five roads form two triangles. What is the value of x? Justify your answer.

Answers

Using sine rule, the value of x in the triangle formed by five roads is 53.36 degrees.

How to find the angle of triangle using sine law?

The value of x can be found using sine rule.

Therefore,

73.2 / sin 37° = 97.6 / sin x

cross multiply

73.2 sin x = 97.6 sin 37°

73.2 sin x = 97.6 × 0.60181502315

73.2 sin x = 58.7371462596

divide both sides by 73.2

sin x = 58.7371462596 / 73.2

x = sin⁻¹ 0.80242003086

x = 53.3618236772

x = 53.36°

Therefore, the value of x is 53.36°

What is a normal distribution?

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

A man gave 35% of his money to his elder on and 40% of the remainder to the younger son.Now, he is left with 11700 rupees.How much money had he?

Answers

Hi ,

Elder son share = 35%

Remainder = ( 100 - 35 ) = 65 %

Younger son share = 40 % of 65

= ( 40 × 65 ) / 100

= 26 %

The percentage left with the man = 100 - 35 - 26

= 100 - 61

= 39%

According to the problem given ,

39% of total amount = Rs 11700

Total amount = ( 11700) / 39%

= ( 11700 × 100 ) / 39

= Rs 30000

The man had Rs 30000.
