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.
What is 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.

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

Last year 858 people attended the Middleton County Fair. This year 1,635 people attended. What was the percent increase from last year to this year? (Round to the nearest percent)
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%

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

Answers:
Problem 9) x = 1Problem 10) x = 3Problem 11) x = 12Problem 12) x = 12==============================================
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.

B)

D)
-6
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.
What is Average Rate of Change of a Function?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.

Chin canned a number of quart jars and a number of pint jars of tomatoes from his garden. A pint is 16 ounces and a quart is 32 ounces. The number of pints he canned is represented by p, and the number of quarts he canned is represented by q. Which equation models the scenario if Chin canned a total of 1,280 ounces? 1280 plus 16 p equals 32 q 1280 plus 32 q equals 16 p 32 q minus 16 p equals 1280 16 p plus 32 q equals 1280
Answer:
16 p plus 32 q equals 1280
16p + 32q = 1,280
Step-by-step explanation:
A pint = 16 ounces
A quart = 32 ounces
p = number of pints he canned
q = number of quarts he canned
if Chin canned a total of 1,280 ounces?
Total ounces canned = 1,280
Equation:
p × 16 ounces + q × 32 ounces = 1,280
16p + 32q = 1,280
The options:
1280 plus 16 p equals 32 q
1,280 + 16p = 32q
1280 plus 32 q equals 16 p
1,280 + 32q = 16p
32 q minus 16 p equals 1280
32q - 16p = 1,280
16 p plus 32 q equals 1280
16p + 32q = 1,280
The correct answer is
16 p plus 32 q equals 1280
16p + 32q = 1,280
Answer:
16p+32q=1280
