Answer:
She can determine that while there is an association between the variables, there is no correlation, and she cannot determine causation.
Step-by-step explanation:
Since there is an arch shape to her graph, we know that as one variable changes, the other changes in the same manner. This means there is an association between the variables.
However, since the graph is not linear, there is no correlation between the variables. Since there is no correlation, we cannot determine causation.
Mark me as brainiest
Answer:
Sample response
Step-by-step explanation:
Because the graph shows a pattern that is an arch shape, Hope can conclude that there is an association between the variables. However, because the relationship is not linear, there is no correlation. The pattern shows that as one variable changes, the other variable changes in the same way. This does not imply that a change in one variable causes the change in the other variable to happen. Hope cannot conclude that there is a causal relationship.

Property of an isosceles triangle,
Opposite angles of the equal sides in an isosceles triangle are equal in measure.
m∠D = m∠F
(2x + 8) = (3x + 4)
3x - 2x = 8 - 4
x = 4
m∠D = m∠F = (3×4 + 4)°
= 16°
m∠D = m∠F = 16°
Since, sum of interior angles of a triangle = 180°
m∠D + m∠E + m∠F = 180°
16° + m∠E + 16° = 180°
m∠E = 180° - 32°
m∠E = 148°

Zoe just lit a new candle and then let it burn all the way down to nothing. The length
of the candle remaining unburned, in inches, can be modeled by the equation
L = 9 – 0.5t, where t represents the number of hours since the candle was lit.
What is the y-intercept of the equation and what is its interpretation in the context of
the problem?
Answer:
9 which represents the the original length of the new candle
Step-by-step explanation:
Since there were 9 inches of candle remaining after 0 hours of burning, that means 9 represents the initial length of the candle, in inches.
What is a solution to (x + 6)(x + 2) = 60?
Answer:
x=4 or -12
Step-by-step explanation:
X+2y=-9
Solve for Y km
Answer:
y = - 1/2x - 4.5
Step-by-step explanation:
Step 1:
x + 2y = - 9 Equation
Step 2:
2y = - x - 9 Subtract x on both sides
Answer:
y = - 1/2x - 4.5 Divide 2 on both sides

Olivia typed 2 pages in 12 minutes. How long will it take her to type 10 pages at this rate?
Answer:
60
Step-by-step explanation:
If Olivia typed 2 pages in 12 minutes, this means that she can type 1 page in 6 minutes. Since we're looking for the amount of time it would take her to type 10 pages, we multiply 6 by 10 to get 60.
Answer:
60 minutes
Step-by-step explanation:
if Olivia writes 2 pages in 12 minutes that means she writes 1 page in 6 minutes. 6 minutes per page times 10 pages equals 60 minutes for 10 pages.
Help plz:))) I’ll mark u brainliest ASAP 10 points(:(:
Answer:
G > F > H
Step-by-step explanation:
In a triangle, the largest side and largest angle are opposite eachother. Similarly, the smallest side and smallest angle are opposite eachother.
We have 3 sides of length 6 cm, 11 cm, and 12 cm. The angle opposite the 6 cm side is the smallest (H). The angle opposite the 14 cm side is the largest (G).
please help asap i don’t understand this.
Answer:
It is the second circle I believe
Step-by-step explanation:
As you can see on the x side is always just going up 1, and the y side is 2 numbers behind the x side in the beginning. But the y side catches up to the x side, which you can see once the x and y side both have positive 1's. The the y side goes up 2 more while the x side only goes up once.

Penny Weights, use the weights of the post 1983 pennies to construct a 98% confidence interval estimate of the standard deviation of the weights of all post-1983 pennies. S=0.0165 n=37. Find confidence interval. a. 0.01231 < Ï < 0.2111 b. 0.01239 < Ï < 0.02111 c. 0.1391 < Ï < 0.2311 d. 0.001219 < Ï < 0.002111
Answer:
c. 0.1391 < Ï < 0.2311
Step-by-step explanation:
The formula for Confidence Interval is given as:
Mean ± z × Standard deviation/√n
Z score for 98% confidence interval = 2.326
Mean = Significance level = 100% - 98%
= 2% = 0.02
Standard deviation = S=0.0165
n= 37
Hence,
Confidence Interval =
0.02 ± 2.326 × 0.0165/√37
0.02 ± 0.0063094687
Confidence Interval
0.02 - 0.0063094687
= 0.1391
0.02 ± 0.0063094687
= 0.2311
Hence, the Confidence Interval = (0.1391, 0.2311)
= c. 0.1391 < Ï < 0.2311

Questions in the picture
Answer:
This is not a function. This is because if there are any repeating x values (the first values of each set) it is not a function. It is okay for there to be repeating y values (the second values of each set) but not x values.
Step-by-step explanation:
I am guessing the question is if this is a function.
Are these lines parallel, perpendicular, or neither? 3y=x+4 and 3x+y=1
Answer:
perpendicular
Step-by-step explanation:
3y = x + 4 in slope intercept form y = 1/3x +4/3
3x + y = 1 in slope intercept form y = -3x +1
the slopes are negative reciprocals of each other so they are perpendicular
Answer:
These lines are perpendicular
Step-by-step explanation:
3y=x+4
[tex]y = \frac{1}{3}x+\frac{4}{3}[/tex]
Slope (m1) = 1/3
3x+y=1
y = -3x + 1
Slope (m2) = - 3
m1 * m2 = [tex]\frac{1}{3}* -3[/tex]
= -1
So, these lines are perpendicular.
If product of two slopes is (-1), then they are perpendicular lines.
If both lines have same slope, then they are parallel.
