Answer:

Set of four data pairs with correlation coefficient r= -0.8 reasonable linear regression data set.

Step-by-step explanation:

Linear regression is a primary type of predictive analysis. It describes does a variable does a useful job. Which variable is significant.

Set of nine data pairs with correlation coefficient r = -0.4

Set of five data pairs with correlation coefficient r= 0.3

Set of four data pairs with correlation coefficient r= -0.8

Setoff six data pairs with correlation coefficient r = 0.6

A setoff four data pair with correlation coefficient r = -0.8 is the valid data set.

Because

r = -0.8

r2 = 0.64,

This is very close to 1 as compared to any other data pair.

Hence, Set of four data pairs with correlation coefficient r= -0.8 reasonable linear regression data set.

Answer:

C "a set of four data pairs with a correlation coefficient r = –0.8"

Answer:

C

Step-by-step explanation:

The value of negative square root of 7 can be determined by either using a calculator or even just solely thinking about it. If we think about, negative square root of 4 is -2 and negative square root of 9 is -3. Therefore, the answer is C. We can also use a calculator to confirm the answer. -√7 is approximately -2.65 and therefore is a value between -2 and -3 which is point C.

The point C (-2.4) best approximates the value of negative square root of 7 on the given number line.

A number system is defined as a system of writing to express numbers.

The square root of 7 is approximately 2.65, so the negative square root of 7 is approximately -2.65.

Among the given points on the number line, the point that is closest to -2.65 is point C, which is at -2.4.

Therefore, point C (-2.4) best approximates the value of negative square root of 7 on the given number line.

Answer:

[tex]\boxed {x = 7}[/tex]

Step-by-step explanation:

[tex]FJ[/tex] and [tex]JH[/tex] is half of the whole measurement of [tex]FH[/tex]. So, to find the value of  [tex]x[/tex], you need to write an expression by using those measurements of both [tex]FJ[/tex] and [tex]JH[/tex]. Then, solve for [tex]x[/tex]:

[tex]FJ = 24[/tex]

[tex]JH = 3x - 3[/tex]

[tex]3x - 3 = 24[/tex]

-Solve:

[tex]3x - 3 = 24[/tex]

[tex]3x - 3 + 3 = 24 + 3[/tex]

[tex]3x = 27[/tex]

[tex]\frac{3x}{3} = \frac{27}{3}[/tex]

[tex]\boxed {x = 7}[/tex]

If this figure was a parallelogram, then the opposite angles would be congruent. This would make angles B and D the same measure

angle B = angle D

x^2+20 = 7x+50

x^2+20-7x-50 = 0 .... get everything to one side

x^2-7x-30 = 0

(x-10)(x+3) = 0 ... see note below

x-10 = 0 or x+3 = 0

x = 10 or x = -3

Note: In this step is where the factoring occurs. To factor, we need to find two numbers that multiply to -30 which is the last term, and also add to -7 which is the middle coefficient. This is a trial and error process. You should find that -10 and 3 both multiply to -30 and add to -7. I suggest making a table as shown below (attached image) to list out all the possible choices.

Perhaps a much more efficient route is to use the quadratic formula.

-----------------

We found two possible solutions for x. If x = 10, then 7x+50 is 7(10)+50 = 120 which is an obtuse angle. If x = -3, then 7x+50 = 7(-3)+50 = 29 which is acute.

Assuming the diagram is drawn to scale, this means angle D is obtuse and we'll go with x = 10 and 7x+50 = 120

Angles A and D add to 180 degrees. This is true for any pair of adjacent angles in a parallelogram.

A+D = 180

A+120 = 180

A = 180-120

-----------------

This answer is based on the assumption that the diagram is drawn to scale and that this quadrilateral is a parallelogram.

Answer:

[tex]\angle A=60\textdegree[/tex]

Step-by-step explanation:

So we have the following parallelogram and we wish to solve for ∠A.

To do so, we will need to solve for x first. Look carefully at the parallelogram...

Notice that ∠A and ∠D are consecutive angles. In other words:

[tex]\angle A+\angle D=180[/tex]

Since we have an equation for ∠D, substitute:

[tex]\angle A+7x+50=180[/tex]

Notice that ∠A and ∠B are also consecutive angles. So:

[tex]\angle A+\angle B=180[/tex]

We know the equation for ∠B. Substitute:

[tex]\angle A+x^2+20=180[/tex]

Since both equations equal 180, we can set them equal to each other:

[tex]\angle A+7x+50=x^2+20+\angle A[/tex]

Let's subtract ∠A from both sides. This gives us:

[tex]7x+50=x^2+20[/tex]

Now, we can solve for x. This is a quadratic, so let's move all the terms to one side. To start off, let's subtract 50 from both sides:

[tex]7x=x^2-30[/tex]

Now, let's subtract 7x from both sides:

[tex]0=x^2-7x-30[/tex]

Solve for x. We can factor.

Here's the trick to factoring. If we have the following:

[tex]0=ax^2+bx+c[/tex]

The we will need to find two numbers, p and q, such that:

[tex]p+q=b\text{ and } pq=ac[/tex]

In our equation, a is 1, b is -7, and c is -30.

So, we want two numbers that sum to -7 and multiply to (1)(-30)=-30.

We can use -10 and 3. -10+3 is -7 and -10(3) is -30. So, let's substitute our b term for -10x and 3x. In other words, we have:

[tex]0=x^2-7x-30[/tex]

Substitute -7x for 3x-10x. This gives us:

[tex]0=x^2+3x-10x-30[/tex]

This is equivalent to our old equation.

Now, we can factor. Factor out a x from the first two terms:

[tex]0=x(x+3)-10x-30[/tex]

And factor out a -10 from the two last terms:

[tex]0=x(x+3)-10(x+3)[/tex]

Since the expressions within the parentheses are the same, we can use grouping to acquire:

[tex]0=(x-10)(x+3)[/tex]

Note that this is essentially the distribute property. If we distribute, we will get the same as above.

Zero Product Property:

[tex]x-10=0\text{ or }x+3=0[/tex]

Solve for x:

[tex]x=10\text{ or } x=-3[/tex]

So, we have two cases for x. Each case will yield a different answer for ∠A.

Case I: x=10

Use our original equation of:

[tex]\angle A+7x+50=180[/tex]

Substitue 10 for x:

[tex]\angle A+7(10)+50=180[/tex]

Multiply:

[tex]\angle A+70+50=180[/tex]

Add:

[tex]\angle A+120=180[/tex]

Subtract 120 from both sides:

[tex]\angle A=60\textdegree[/tex]

So, in our first case, ∠A is 60°

Case II: x=-3

Again, same equation:

[tex]\angle A+7x+50=180[/tex]

This time, substitute -3 for x. This yields:

[tex]\angle A+7(-3)+50=180[/tex]

Multiply:

[tex]\angle A-21+50=180[/tex]

Add:

[tex]\angle A+29=180[/tex]

Subtract 29 from both sides:

[tex]\angle A=151\textdegree[/tex]

So, in our second case, ∠A is 151°

However, 151° doesn't seem likely with how the figure is drawn.

Therefore, our final answer is 60°.

And we're done!

Answer:

0.0520

Step-by-step explanation:

In this expression, we conclude that 1 is the least significant figures after decimal in this problem.  The answer will be 0.0520.

Significant figures is the figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

The rule apply for the multiplication and division is that the least number of significant figures in any number of the problem determines the number of significant figures in the answer.

The rule apply for the addition and subtraction is that the least precise number present after the decimal point determines the number of significant figures in the answer.

The given expression is: 0.0702 - 1.35

0.0702 - 1.35

= 0.0520

In this expression, we conclude that 1 is the least significant figures after decimal in this problem.

Answer:

y = -40

Step-by-step explanation:

y/-4 = 10

y = -40

Hey there!☺

[tex]Answer:\boxed{y=-40}[/tex]

[tex]Explanation:[/tex]

[tex]\frac{y}{-4}+5=15[/tex]

In our first step, we will simplify both sides of the equation:

[tex]\frac{x-1}{4}y+5=15[/tex]

Now we will subtract 5 from both sides:

[tex]\frac{-1}{4}y+5-5=15-5\\\frac{-1}{4}y=10[/tex]

Now in our last step, we will multiply both sides by 4/(-1):

[tex](\frac{4}{-1})\times(\frac{-1}{4}y)=(\frac{4}{-1})*(10)\\ y=-40[/tex]

y=-40 is your answer.
