You use a line best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your data set is -0.833. How confident can you be that your predicted value will be reasonably close to the actual value? Why or why not?

Answer:

false

Step-by-step explanation:

This is because -5m=-20

m=-20/-5

m=4

Step-by-step explanation:

False

because there two - are cancelled

Answer:

8a   Yes

8b   f(5) = 1

8c   (0, -0.5)

Step-by-step explanation:

8a

Yes, since it passes the vertical line test.

8b

f(5) = 1

8c

(0, -0.5)

Answer:

Step-by-step explanation:

(x₁, y₁)  = (-9, 7)    & (x₂ , y₂) = (9 , -3)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

          [tex]= \frac{-3-7}{9-[-9]}\\\\= \frac{-3-7}{9+9}\\\\=\frac{-10}{18}\\\\= \frac{-5}{9}[/tex]

Answer:

[tex]\frac{X}{UB} = H[/tex] is the answer.

Step-by-step explanation:

Since we are solving for H, we need to get rid of everything that isn't H.

X = UHB can also be shown as X = UBH

Divide by UB on both sides to equal to H.

[tex]\frac{X}{UB} = H[/tex]

This is your answer.

Answer:

3.5/1 (or just 3.5)

Step-by-step explanation:

If y = a/n, then the constant proportionality is 3.5/1 or 7/2

Think of this as "rise over run" (we are basically finding the slope)

Step-by-step explanation:

if it was for example 5(y+3)=55

then you could simplify it to 5y+15=55

then 5y=40

y=8

Answer:

Amount of dividend that PRH will receive is $833,625.

Step-by-step explanation:

The following are given in the question:

Total number of shares of Marks Brothers = 78,000

Percentage of shares of Marks Brothers held by PRH = 19%

Dividend per share = $56.25

Therefore, we can now proceed as follows:

Number of shares of Marks Brothers held by PRH = Total number of shares of Marks Brothers * Percentage of shares of Marks Brothers held by PRH = 78,000 * 19% = 14,820

Amount of dividend that PRH will receive = Number of shares of Marks Brothers held by PRH * Dividend per share = 14,820 * $56.25 = $833,625

The amount of dividend that PRH will receive is $833,625.

Number of shares of Marks Brothers held by PRH is

= Total number of shares of Marks Brothers × Percentage of shares of Marks Brothers held by PRH

= 78,000 × 19%

= 14,820

Now  

Amount of dividend that PRH will receive = Number of shares of Marks Brothers held by PRH × Dividend per share

= 14,820 × $56.25

= $833,625

Answer:

The result of the correct substitution gives:

x = 3/7 and y = 27/7

Step-by-step explanation:

From the given information:

y = 2x + 3  ---- (1)

3x + 2y = 9 ---- (2)

By using substitutional method

Substitute the value of y = 2x +3 into equation (2)

So,

3x + 2(2x + 3) = 9

3x + 4x + 6 = 9

7x = 9 - 6

7x = 3

x = 3/7

From equation (1), let replace the value of  x  to be 3/7

So,

y = 2x + 3

y = 2(3/7) + 3

y =  6/7 + 3

y = 27/7

Answer:

x = 40°

Step-by-step explanation:

Since, the measures of the angles subtended by the same segment are equal.

Therefore, x = 40°

Just remember that total angle above straight line is 180

Answer:

steve is 23 and julie is 28

Step-by-step explanation:

51 - 5 = 46

46/2 = 23

steve is 23, but julie is 5 years older than him, so

23 + 5 = 28

28+23=51

Answer: lol, I tried solving this but this is harder then what I had in 8th grade.

Step-by-step explanation:

Answer:

Step-by-step explanation:

given the expression;

cos(2x) = cos(x)

According to trig identity;

cos(2x) = cos(x+x)

cos(2x) = cos x cos x - sinx sinx

cos(2x) = cos²(x)-sin²(x)

cos(2x) = cos²(x)-(1-cos²x)

cos(2x) = cos²(x)+cos²x-1

cos(2x) = 2cos²(x)-1

2cos²(x)-1 = cos(x)

let P = cosx

2P²-1 = P

2P²-P-1 = 0

Factorize;

2P²-2P+P-1 = 0

2P(P-1)+1(P-1) = 0

2P - 1 = 0 and P-1 = 0

P = 1/2 and 1

cosx = 1/2 and cos x = 1

x = arccos 1/2

x = π/3

Also;

x = arccos1

x = 0

Hence the value of x are 0 and  π/3

Also the angle = π+ π/3 = 4π/3

The angles are 0, π/3 and 4π/3

Answer:43.47

Step-by-step explanation: you have to mulitply 63 and 69  and you will get   43.47

Description

To calculate a percent of a number you must find the total amount or the whole number.

After that Divide the number that you wish to determine the percentage for

Then multiply the value from step two by 100.

In this case the answer will be 43.47

64 percent of 69 = 43.47

Answer: 43.47

Step-by-step explanation:

Answer:

0.82

Step-by-step explanation:

Answer: Regular Decagons: All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1440 degrees (from above) And there are ten angles...So, the measure of the angle of a regular decagon is 144 degrees.
