Answer:

Weak Positive Correlation

Step-by-step explanation: I think that’s correct not 100 percent sure

The strength of the linear association between the height and the length of these rectangles is option A. Weak negative correlation.

In this, the both variables should be response to one another here the relationship is not so strong.

So the  correlation coefficient for the data  that represent the linear relationship between the height and length should be weak

hence, the option a is correct.

Answer:

Yes

Step-by-step explanation:

You are using the x values once, so it will pass the vertical line test.

{(3,4), (5,0), (2,4), (-5,-5)} the relation is a function.

A relation is a function if it has only One y-value for each x-value.

The relation is {(3,4), (5,0), (2,4), (-5,-5)}

Relation on a set may, or may not, hold between two given set members.

Three comma four comma five comma zero two comma four comma minus five comma minus five.

{(3,4), (5,0), (2,4), (-5,-5)} the relation is a function, because in (x,y) the x terms are not repeated.

For every y value there is a unique x value.

Hence, {(3,4), (5,0), (2,4), (-5,-5)} the relation is a function.

Answer: -3

Step-by-step explanation: just multiply

The best estimate of the average rate of change for the function graphed over the interval 1 ≤ x ≤ 3 is 3.

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

The interval given is 1 ≤ x ≤ 3.

The graph of the function is given below.

It can be clearly seen that,

The y value corresponding to x = 1 is y = f(1) = 2.

So one point on the graph is (1, 2).

The y value corresponding to x = 3 is y = f(3) = 8.

So the other point on the graph is (3, 8).

Average rate of change over 1 ≤ x ≤ 3 = [f(3) - f(1)] / [3 - 1]

                                                               = [8 - 2] / [2]

                                                               = 6/2

                                                               = 3

Hence the best estimate for the average rate of change of function over the interval 1 ≤ x ≤ 3 is 3.

b) -14

c) -3

d) -96

Step-by-step explanation:

a) The parenthesis indicate multiplication.

b) Minus and plus gives subtraction, and the sign you put behind the number is the sign of the largest number you have (in this case it's 21 since we ignore the -)

c) They already have common denominators, all that's left is to do [tex]\frac{-7 -2}{3} = \frac{-9}{3} = -3[/tex]

Answer:x = -0.1290322581

Step-by-step explanation:

Simplifying

9x + -4(1 + 10x) = 0

9x + (1 * -4 + 10x * -4) = 0

9x + (-4 + -40x) = 0

Reorder the terms:

-4 + 9x + -40x = 0

Combine like terms: 9x + -40x = -31x

-4 + -31x = 0

Solving

-4 + -31x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + -31x = 0 + 4

Combine like terms: -4 + 4 = 0

0 + -31x = 0 + 4

-31x = 0 + 4

Combine like terms: 0 + 4 = 4

-31x = 4

Divide each side by '-31'.

x = -0.1290322581

Answer:

the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively

Step-by-step explanation:

The computation of the amount that he makes last week and in the year 2011 is as follows:

= Sale value of the stocks × earning percentage × number of weeks in a year

= $7,000 × 11% × 52 weeks

= $40,040

hence, the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively

We simply applied the above formula so that the correct value could come

Answer:

91%

Step-by-step explanation:

The first step is to calculate the increase

= 1635-858

= 777

Therefore the percent increase can be calculated as follows

= 777/858 × 100

= 0.905× 100

= 90.5 %

= 91%

Hence the percentage increase is 91%

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

Explanation:

For problems 9 through 12, we'll use the same set of steps. Recall that any parallelogram has the property that the adjacent angles are supplementary. This means close by angles add to 180. Each of the four diagrams show pairs of adjacent angles.

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

In problem 9, we have the following steps

(79x-1) + (102) = 180

79x + 101 = 180

79x = 180-101

79x = 79

x = 79/79

x = 1

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

Problem 10 is the same idea

(85) + (30x+5) = 180

30x+90 = 180

30x = 180-90

30x = 90

x = 90/30

x = 3

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

Problem 11

(55)+(9x+17) = 180

9x+72 = 180

9x = 180-72

9x = 108

x = 108/9

x = 12

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

Problem 12

(3x+12)+(132) = 180

3x+144 = 180

3x = 180-144

3x = 36

x = 36/3

x = 12

Answer:

9. X = 1

10. X = 3

11. X = 12

12. X = 12

Step-by-step explanation:

9.

1) 79x - 1 + 102 = 180

2) 79x + 101 = 180

3) Subtract 101 from both sides

4) 79x = 79

5) x = 1

10.

1) 85 + 30x + 5 = 180

2) 30x + 90 = 180

3) Subtract 90 from both sides

4) 30x = 90

5) x = 3

11.

1) 55 + 9x + 17 = 180

2) 9x + 72 = 180

3) Subtract 72 from both sides

3) 9x = 108

4) X = 12

12.

1) 3x + 12 + 132  = 180

2) 3x + 144 = 180

3) Subtract 144 from both sides

4) 3x = 36

5) x = 12

All answers have been checked by plugging the X back into the equation.
