The graph shows a residual plot of values from a line of regression. Use the plot to analyze the results of the correlation.

Answer:

6 units.

Step-by-step explanation:

Distance = √ [(7 - 1)^2 + (-4-(-4))^2]

= √(36 + 0)

= 6 units.

Answer:

  x ∈ {{0.30773985, 1.26305647, 1.87853618, 2.83385280, 3.44933251, 4.40464913, 5.02012883, 5.97544545}

Step-by-step explanation:

Divide by the coefficient of the sine function, take the root, then use the arcsine function to find the angles.

  [tex]3\sin^2(2x)=1\\\\\sin^2(2x)=\dfrac{1}{3}\\\\ \sin(2x)=\pm\sqrt{\dfrac{1}{3}}\\\\2x=\pm\arcsin\left(\dfrac{\sqrt{3}}{3}\right)+n\pi\\\\x=\dfrac{\pm\arcsin\left(\dfrac{\sqrt{3}}{3}\right)+n\pi}{2}[/tex]

The numerical values are approximately ...

  x ∈ {{0.30773985, 1.26305647, 1.87853618, 2.83385280, 3.44933251, 4.40464913, 5.02012883, 5.97544545}

Answer:

28

Step-by-step explanation:

Neat Question.

Thanks for posting.

The straign line (horizontal) makes an isosceles triangle inside the circle. So the bottom angle of the triangle is also 59 degrees. The central angle of the interior triangle is

180 - 59 - 59 = 62.

x and the 62 degree angle are complementary -- both are in the 90 degree angle triangle made by the tangent. x + 62 = 90

x = 90 - 62 = 28

Answer:

x = 28°

Step-by-step explanation:

PQ is tangent to circle O, ∠OPQ = 90°

∠QPR = 90-59 = 31°

mOP = mOR (radius)          ∠PRO = ∠OPR = 59°    (isosceles triangle)

∠PRO = ∠QPR + x°       (triangle exterior angle)

x = 59° - 31° = 28°

Answer:

b) use a two-sided test instead of a one sided test.

Step-by-step explanation:

If we are using a significance level of 0.05, then the two-tailed test assigns half alpha to test for statistical significance in one direction and half alpha to test statistical significance in the other direction. This implies that .025 is present in each tail of the test statistical distribution. When using the two-tailed test, regardless of the direction of the relationship you assume, we test the possibility of the relationship in both directions.

Answer:

20percent is the same as 20/100 so .2

Step-by-step explanation:

GIVE BRAINLIEST

Answer:

0.2

Step-by-step explanation:

Whenever you have a percentage

move the decimal over 2 places.

20 = 0.2

Another example

70% = 0.7

287% = 2.87

Answer:

the answer is

9(2p+1)

Answer:

18p +9

Step-by-step explanation:

Because you add the numbers in front of the p's (10+8) and then you add 10 plus -1, which is 9.

Hope this helps! Have a good day and remember to be tiger fierce!! :)

Answer:

-3x + 6 and -3(x - 2)

Step-by-step explanation:

Given

[tex]3x - 7 - 6x + 13[/tex]

Required

An equivalent expression

[tex]3x - 7 - 6x + 13[/tex]

Collect Like Terms

[tex]3x - 7 - 6x + 13 = 3x - 6x - 7 + 13[/tex]

[tex]3x - 7 - 6x + 13 = -3x+6[/tex]

This can be simplified further as:

[tex]3x - 7 - 6x + 13 = -3(x-2)[/tex]

Answer: D

Step-by-step explanation:

Answer:

Step-by-step explanation:

The number of chapters read = y

Number of days spent to read = x

Slope of the line = [tex]\frac{5}{4}[/tex] ≈ 1.25

y-intercept = 2

Slope means "number of pages read per day"

For slope = 1.25 means "1.25 pages read per day"

y-intercept means "Number of pages read initially"

y-intercept = 2 means "2 pages have been already read"

Answer:

≈ 13.33 years

Step-by-step explanation:

The population of Frisco ISD after t years is given by the following equation:

[tex]y(t) = 46000(1.06)^{t}[/tex]

How many years will pass until the population of Frisco ISD is at 100,000 students?

This is t for which [tex]y(t) = 100000[/tex]. So

[tex]y(t) = 46000(1.06)^{t}[/tex]

[tex]46000(1.06)^{t} = 100000[/tex]

[tex](1.06)^{t} = \frac{100000}{46000}[/tex]

[tex]\log{(1.06)^{t}} = \log{\frac{100000}{46000}}[/tex]

[tex]t\log{1.06} = \log{\frac{100000}{46000}}[/tex]

[tex]t = \frac{\log{\frac{100000}{46000}}}{\log{1.06}}[/tex]

[tex]t = 13.33[/tex]

So the answer is ≈ 13.33 years

Answer: 53.1

Step-by-step explanation:

Answer:

$290

Step-by-step explanation:

We can use the equation that Skate Land created to find the total cost

C = 7.50p + 65

p = people so if we have 30 people, we have to solve 7.50 x 30

C = 225 + 65

we can now add the flat fee of $65 to get the total cost for the birthday part

C = $290

hope this helps :)

Answer:

$1.25 & $10.25

Step-by-step explanation:

Let c be the cost of renting one chair and t be the cost of renting table. We're given two equations:

#1. 5c + 3t = 37

#2. 2c + 6t =64

We have a system of equations. Using our system of equations calculator, we can solve this problem any of 3 ways below:

Answer:

2827.4

Step-by-step explanation:

V = πr2h this is the equation that can be used for these problems.

V= π(10)2(9)

the radius is 10 because the diameter is 20. Divide the given diameter by 2 to find the radius.

Answer:

f(x) = -4x-1

f(7) = -(4)(7)-1

f(7) = -29

g(x) = 4x^2 - x

g(-4) = 4(-4)^2 - (-4)

g(-4) = 4(16) + 4

g(-4) = 64 + 4

g(-4) = 68
