Answer:
Seems to be no correlation at all.
Answer:
anges between -1 and +1 and quantifies the direction and strength of the linear association between the two variables. The correlation between two variables can be positive (i.e., higher levels of one variable are associated with higher levels of the other) or negative (i.e., higher levels of one variable are associated with lower levels of the other).
The sign of the correlation coefficient indicates the direction of the association. The magnitude of the correlation coefficient indicates the strength of the association.
For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables.
It is important to note that there may be a non-linear association between two continuous variables, but computation of a correlation coefficient does not detect this. Therefore, it is always important to evaluate the data carefully before computing a correlation coefficient. Graphical displays are particularly useful to explore associations between variables.
The figure below shows four hypothetical scenarios in which one continuous variable is plotted along the X-axis and the other along the Y-axis.

Answer: The answer to this question is measure of angle DGE = 1/2 (measure of arc DGE - measure of arc DE).
Step-by-step explanation:
The formula for an angle outside of the arc can be written as measure of angle x is equal to the larger arc starting from the ends of the segments forming x subtracted to the smaller arc starting from the ends of the segments forming x divided by 2.

If x = 15 units and h = 4 units, then what is the area of the triangle shown above?
A. 8 square units
B. 30 square units
C. 60 square units
D. 90 square units
Answer: B. 30 square units
Step-by-step explanation:
Area of triangle formula is base x height divided by 2 so we do 15 * 4 = 60/2 = 30 units

The angle measurements in the diagram are represented by the following expressions.
Answer:
30°Step-by-step explanation:
A and B are same side interior angles and hence supplementary:
m∠A + m∠B = 180°Substitute values and solve for x:
6x - 18 + 14x + 38 = 18020x + 20 = 18020x = 160x = 160/20x = 8Find the measure of ∠A:
m∠A = 6*8° - 18° = 30°Milton bought a bike that costs 84.21. THe sales tax rate is 6% How much did miltion pay for the bike altogether??

Answer: The mean is 6.
Step-by-step explanation: First you add all of the numbers together getting a total of 48. Next to find the mean you divide them by the total number of "dots". Lastly, you get the answer of 6 which is your mean.
Answer:
6.
Step-by-step explanation:
First you take the data on the dot plot, and write the numbers down from least to greatest.
The data set:
2,3,6,6,7,8,8,8
Now that you have the data reordered in a easier way to read, add up all the numbers that you got from the dot plot.
2+3+6+6+7+8+8+8=48
Next we count all the number in the data set we made.
2,3,6,6,6,7,8,8,8 = 8
The amount of numbers in this data is 8.
Lastly we then divide 48 by 8.
48/8= 6
So your answer is 6!
hello there,
can someone please help me with this question
Answer:
10 sides.
Step-by-step explanation:
Two same interior angles + 72 degrees = 360.
Thus, the interior angle of the polygon is [tex]\frac{360-72}{2} =144[/tex].
The formula to find the interior angle of a polygon is [tex]\frac{180(n-2)}{n}[/tex]
[tex]\frac{180(n-2)}{n} =144[/tex]
Multiply both sides by n:
[tex]\frac{180\left(n-2\right)}{n}n=144n[/tex]
[tex]180\left(n-2\right)=144n[/tex]
Expand:
[tex]180n-360=144n[/tex]
Add 360 to both sides:
[tex]180n-360+360=144n+360[/tex]
[tex]180n=144n+360[/tex]
Subtract 144n from both sides:
[tex]180n-144n=144n+360-144n[/tex]
[tex]36n=360[/tex]
Divide both sides by 36:
[tex]\frac{36n}{36}=\frac{360}{36}[/tex]
[tex]n=10[/tex]

PLEASE HELP!!! I have no clue how to find the perimeter of MNP
Answer:
130
Step-by-step explanation:
Triangle MNP is twice the size of triangle SRP. So 2(x+4)=5x-34.
Distribute: 2x+8=5x-34
Add 34 on both sides: 2x+42=5x
Subract 2x on both sides: 42=3x
Divide both sides by 3: 14=x
If x=14, then 5x-34
is 5(14)-34=70-34=36.
The perimeter of the triangle MNP is
MN+NP+PM.
MN is 36
NP is doubled the 22 because triangle MNP is twice the size of triangle MQS. So NP is 44.
PM is doubled the 25 because triangle MNP is twice the size of triangle QNR. So PM is 50.
The perimeter of the triangle MNP is
MN+NP+PM
=36+44+50
=130

B. 0.017920
C. 0.000256
D. 0.00000256
Answer:
D 0.00000256
Step-by-step explanation:
[tex]5^{28} *5^{-32}*5^{-4}=5^{28-32-4}=5^{-8}=\frac{1}{5^{8}} =0.00000256[/tex]
Answer:
B. 0.000256
Step-by-step explanation:
5^28 . 5^- 32 . 5^ -4
= 5^( 28 - 32 - 4 )
= 5^( 28 - 36 )
= 5^- 8
= 1 / 5^8
= 1 / 390625
= 0.000256
What is the volume of the solid figure?
Solid is made up of 2 cuboids. First cuboid has length as 15 in., height as 5 in. and width as 5 in. Second cuboid has length as 5 in., height as 10 in. and width as 5 in. HELP ASAP I HAVE 1- MINUTES LEFT!!!
Answer:
The volume of the solid figure = Volume of the first cuboid + Volume of the second cuboid
The volume of the solid figure = 15×5×5 + 5×5×10
Or, The volume of the solid figure = 375 + 250
Or, The volume of the solid figure = 625 inch³
Therefore, the volume of the solid figure = 625 inch³
