The statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.
What is the correlation coefficient?Correlation coefficient is used to calculate how strong the relationship is between the two variables.
When there is a statistical relationship between two or more variables, then they are said to be in correlation.
Types of correlation-
Positive correlation coefficient- When the value of correlation coefficient is positive, then the value of one variable increases with increase in other variable.Negative correlation coefficient- When the value of correlation coefficient is negative, then the value of one variable decreases with increase in other variable.
The graph shows a volume of ice cubes versus temperature in degrees Celsius.
For a perfect correlation, -1 or +1 values is ideal. Here, some relation can be seen in a negative straight line, which suggest that the correlation coefficient is not close to zero.
Both volume and temperature has strong correlation for linear line where, temperature is the explanatory variable.
Thus, the statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.

An item cost $80 but you were charged $56. What was the percent discount for that item?

x = 56/80
x = 0.7
So $56 is 70% of $80. Then the discount is 30% (100% - 70% = 30%)
The length of the lunch area is 6 1/2 times it's width. If the width of the area is 10 6/13 feet, what is the length in simplest form?
Answers
Answer:the length of the Lunch area= 68 feet
Step-by-step explanation:
Since width of lunch area is given = 10 6/13 feet
and Length of the lunch area is 6 1/2 times it's width.= 6 1/2 x Width
Length = 6 1/2 x 10 6/13
changing to improper fraction foe easy solving
13/2 x 136/13
13 cancels out 13, we are left with
136/2 =68 feet

– 6 £ 2y < 5
y is an integer.
Write down all the possible values of y.
Answers
Answer:
all values less than 5.5
Step-by-step explanation:
Given the inequality expression – 6 + 2y < 5
We are to find all the possible values of x
-6 + 2 y < 5
Add 6 to both sides
-6 + 2y + 6 < 5 + 6
2y < 11
Divide both sides by 2
2y/2 < 11/2
y < 11/2
y < 5.5
hence the possible values of y are all values less than 5.5
Write an equation that represents the line. Use exact numbers (i will mark you brainliest)✅
Answers
Answer:
y=4/5x-18/5
Step-by-step explanation:
there are multiple ways we can find the slope, let's use two points and the point slope form y=mx+b for this equation. we can find the slope by using the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
in this case, we can use the two points (-3,-6), (2,-2)
y2=-2, y1=-6, x2=2, x1=-3
so, the equation is [tex]\frac{-2-(-6)}{2-(-3)}[/tex]
this reduces to 4/5
our slope is 4/5, so the equation for now is y=4/5x+b
let's use (2,-2) to find b. the y is -2, x is 2
-2=4/5(2)+b
-2=8/5+b, multiply both sides by 5:
-10=8+5b, subtract 8 from both sides
-18=5b, divide by 5
-18/5=b
our final equation is y=4/5x-18/5

why is it important for jews to understand the characteristics of God
Answers
Answer:
To conclude, the characteristics of God provide a foundation by which Jews can look up to and mimic behaviour and develop good morals. They can come to understand and appreciate God, particularly as he is unseen, and this allows for them to be able to believe without question e.g. God is all knowing. G-d is all knowing and has a purpose for the world. This gives people faith to believe in God and wait for the Messianic Age to come, and have patience in God’s plan. However, it can be argued that there is no real point in having being taught characteristics of a being which can not be seen. With characteristics, some may argue that the concept of God can still not be understood, and the idea is unclear, particularly as the descriptions are supposedly by God himself, in which many Jews do not believe, as they are culturally and ethnically Jewish, rather than religiously Jewish.

Answer:
x= 8
Step-by-step explanation:
1. Expand.
3x-9=-2x+31
2. Add 9 to both sides.
3x=-2x+31+9
3. Simplify -2x+31+9 to -2x+40.
3x=-2x+40
4. Add 2x to both sides.
3x+2x=40
5. Simplify 3x+2x+5x.
5x=40
6. Divide both sides by 5.
x = 40/5
7. Simplify 40/5 to 8.

What is the domain of y = tan x? A. (–∞, ∞) B. C. all D. all
Answers
Given:
The function is
[tex]y=\tan x[/tex]
To find:
The domain of the given function.
Solution:
We know that, domain is the set of x-values or input values.
We have,
[tex]y=\tan x[/tex]
[tex]y=\dfrac{\sin x}{\cos x}[/tex]
The functions sin x and cos x are defined for all real values of x. So, the function tan x is defined for all real values of x except those value for which cos x = 0.
So, domain is [tex]-\infty<x<\infty, x\neq \dfrac{\pi}{2}+n\pi[/tex].
Note: All options are incorrect.

[tex]y = 17(3^{x} )[/tex]
Step-by-step explanation:
When x = 0, y = 17 So, [tex]17 = kb^{0} = k(1) = k[/tex]
Now, [tex]y = 17b^{x}[/tex]
When x = 5, y = 4131 So, [tex]4131 = 17b^{5}[/tex]
[tex]b^{5} = 4131/17 = 243 = 3^{5}[/tex]
b = 3
