[tex]\sqrt{10}[/tex]

Step-by-step explanation:

Define your points x1, y1 and x2, y2

(x1,y1) = (-4,-2)

(x2,y2) = (-5,1)

Use the distance formula, the distance between the center and that point is the radius of the circle.

[tex]\sqrt{(x2-x1)^{2} +(y2-y1)^{2}}\\\sqrt{(-5--4)^{2} +(1--2)^{2}}\\\\\sqrt{(-1)^{2} +(3)^{2}}\\\\\sqrt{1 +9}\\\\\sqrt{10}\\[/tex]

Answer:

3/10 chance.

Step-by-step explanation:

Since Theoretical Probability is number of favorable outcomes over number of total outcomes, You can see it here that there are two l's and one c. This means that you will have 3 chances to get the letter you want. There are also 10 different letters. This means that you have a 3/10 chance of getting an l or c.

The volume of the solid generated by revolving the region bounded by the given curve and lines y = 2x, y = 2, x = 0 about the x-axis will be  

V = 8π/3

When the integration is done in the three dimensions in the three coordinates x,y and z then we will call it as a volume integration.

I set y=2x = y=2 to find where the intersect each others so I can have my boundaries for integration.

You goal is to find the area so you can integrate around that area. We're revolving around the x-axis so the area will be a circle.

V = ∫A(x)dx =  ∫(πr²)dr

Since we have two different radius, we subtract them from each others.

∫(πr₂² - πr₁²)dr

∫(π(2)² - π(2x)²)dr

∫(4π - 4πx²)dr

4π∫(1 - x²)dr

integrate from 0 to 1 since that's where our boundary is.

V = 4π∫(1 - x²)dr = 8π/3

Hence the volume of the solid generated by revolving the region bounded by the given curve and lines y = 2x, y = 2, x = 0 about the x-axis will be V = 8π/3

Step-by-step explanation:

divide 14 by 7 to get 2. IT is 2 tests a week so multipy 7 by 2 to get 14 then just add 2 to get 16. you added two meaning you added a week because each week is two tests so the answer will be 8 weeks.

Tim have to attend a total of 8 weeks this quarter before he will have taken a total of 16 quizzes.

The unitary method is a process for solving a problem by first finding the value of a unit, and then finding the necessary value by multiplying the single unit value.

According to the problem,

Tim took 14 quizzes over the course of 7 weeks.

The total combination will be, 45195 if the selecting dance troupe with 6 girls and 7 boys out of 20 girls and 15 boys who auditioned.

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have:

Selecting a dance troupe with 6 girls and 7 boys out of 20 girls and 15 boys who auditioned.

It is a combination problem:

Selecting 6 girls out of 20 = C (20, 6)

Selecting 7 boys out of 15 = C (15, 7)

Total combination = C (20, 6) + C (15, 7)

= 38760 + 6435

= 45195

Thus, the total combination will be, 45195 if the selecting dance troupe with 6 girls and 7 boys out of 20 girls and 15 boys who auditioned.

Answer:

0.416

Step-by-step explanation:

The correct equation must have a slope of 3/2. The required equation is y=3/2x

The standard equation of a line is y = mx + b

where;

m is the slope

b is the y-intercept

Given the following equation

y=−2/3x+1

The slope of the line is -2/3

For two lines to be perpendicular, the product of their slope must be zero.

mm1 = 01
-2/3m = -1
m = 3/2

This shows that the correct equation must have a slope of 3/2. The required equation is y=3/2x

Answer:

m∠C = 110.9° (1 dp)

Step-by-step explanation:

The largest angle in a triangle is opposite the longest side.

Therefore, from inspection of the diagram, angle C is the largest angle since length AB is the longest side length.

To find angle C, use the cosine rule:

[tex]\sf c^2=a^2+b^2-2ab \cos C[/tex]

(where a, b and c are the sides, and C is the angle opposite side c)

Given:

Substituting the given values into the formula and solving for C:

[tex]\implies \sf c^2=a^2+b^2-2ab \cos C[/tex]

[tex]\implies \sf 15^2=11^2+7^2-2(11)(7) \cos C[/tex]

[tex]\implies \sf 225=170-154 \cos C[/tex]

[tex]\implies \sf \cos C=\dfrac{225-170}{-154}[/tex]

[tex]\implies \sf \cos C=-\dfrac{5}{14}[/tex]

[tex]\implies \sf C=\cos ^{-1}\left(-\dfrac{5}{14}\right)[/tex]

[tex]\implies \sf C=110.9248324...^{\circ}[/tex]

Therefore, m∠C = 110.9° (1 dp)

A statement which proves that the diagonals of square PQRS are perpendicular bisectors of each other is: option D.

Mathematically, the slope of a line is given by the following formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

For line RP, we have:

[tex]Slope = \frac{9\;-\;2}{5\;-\;4}\\\\Slope = \frac{7}{1}[/tex]

Slope RP = 7.

For line SQ, we have:

[tex]Slope = \frac{6\;-\;5}{1\;-\;8}\\\\Slope = \frac{1}{-7}[/tex]

Slope SQ = negative one-sevenths.

For the midpoint, we have:

In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).

Midpoint on x-coordinate = (8 + 1)/2 = 9/2 = 4.5.

Midpoint on y-coordinate = (9 + 2)/2 = 11/2 = 5.5.

In conclusion, a statement which proves that the diagonals of square PQRS are perpendicular bisectors of each other is that the midpoint of both diagonals is (4.5, 5.5), the slope of RP is 7, and the slope of SQ is negative one-sevenths.

The total population mean must be close to $47,600 based on statistical inference.

The entire population mean must be close to $47,600. Then the correct option is C.

The mean is the simple definition of the average of a bunch of numbers. In statistics, one of the markers of central tendency is the mean.

The average is referred to as the arithmetic mean.

It's the ratio of the number of real observations to the total number of observations.
