Answer:
Step-by-step explanation:
13.
m1 is 120 because angle 120 and angle 1 are tranversal angle
So now we know that angles m1 and m2 are vertically opposite angle
Then m2 = 120
m1 = 120
m2 = 120
14.
angle 1 and 105 have the sum of 180 because they are Interior angles on the same side of the transversal
So angle 1 equals 180-105=75
angle 2 and angle 1 are on a line so the sum of the 2 angles are 180
So: 180 - 75 = 105
m1 = 105
m2 = 75

dr. guidry has decided to examine one of her relationships with a scatterplot to double-check for a curvilinear relationship. which relationship will be most important for her to examine?
Answers
Linear regressions can help to examine a curvilinear relationship.
It is possible for two variables to have a relationship known as a curvilinear relationship, in which one variable rises along with the other, but only until a certain point, beyond which the other variable falls as the rise of the first continues.
To evaluate the relationship between two numerical variables visually, scatterplots are utilized. Usually, the X axis represents the explanatory variable and the Y axis represents the dependent variable.
By generating a line that best fits your data, regression takes correlation a step further. While a straightforward linear regression analysis still gives us the R2 value, it now gives us a number that indicates the strength (slope) of the association between X and Y. This knowledge improves our comprehension of the underlying relationship and can be applied to forecast Y values given a certain value of X. However, instead of testing the null hypothesis that the slope of the line depicting the relationship between X and Y is zero, T-tests are now employed.
Hence linear regressions can help to examine a curvilinear relationship.

Find the missing number so that the equation has no solutions. -4(-X + 8) = -3(2x + 7) + __x + 9
Answers
In order to have an equation with no solution, the variable x should not appear in the equation and the final sentence must be false.
So, using the variable 'y' to represent the missing number and simplifying the equation, we have:
[tex]\begin{gathered} -4(-x+8)=-3(2x+7)+yx+9 \\ 4x-32=-6x-21+9+yx \\ 4x+6x-yx=32-21+9 \\ 10x-yx=20 \\ (10-y)x=20 \end{gathered}[/tex]Since we want the variable x to disappear (this way we will have 0 = 20, which is false), we need the coefficient (10 - y) to be zero:
[tex]\begin{gathered} 10-y=0 \\ y=10 \end{gathered}[/tex]So the missing number is 10.

Day 5 = 22 pushups (19+3)
Day 6 = 25 pushups (22+3)
Day 7 = 28 pushups (25+3)
Day 8 = 31 pushups (28+3)

2. Kieran, Jermaine and Chris play football. Kieran scored 8 more goals than Chris Jermaine scored 5 more goals than Kieran. Altogether they have scored 72 goals. How many goals did they each score?
Answers
Answer:
Step-by-step explanation:
k = x+8
c= x+5
j= x+5
3x+18=72
x = 18
Chris = 23
Kieran = 26
Jermaine = 23
Answer:
Chris = 17 goals
Kieran = 25 goals, and
Jermaine = 30 goals
Step-by-step explanation:
Let K, J, and C stand for the goals scored by Kieran, Jermaine, and Chris, respectively.
We learn that:
K = C + 8 [Kieran scored 8 more goals than Chris]
J = K + 5 [Jermaine scored 5 more goals than Kieran]
K + J + C = 72 [Altogether they have scored 72 goals]
-----
We have 3 equations and 3 unknowns. Therefore, we should be able to find a solution by rearranging and substituting.
Let's start with K + J + C = 72 and find ways to eliminate two of the three variables.
We can substitute for K since K = C + 8
K + J + C = 72
(C+8) + J + C = 72
Rearrange:
2C+8 + J = 72
We can also substitute for J since J = K + 5
2C+8 + J = 72
2C+8 + (K + 5) = 72
Again, we can substitute for K since (K = C + 8)
2C+8 + (C+8) + 5 = 72
2C+8 + (C+8) + 5 = 72
3C +21 = 72
3C = 51
C = 17
---
Since C = 17, we can find K with K = C + 8
K = C + 8
K = 17 + 8
K = 25
---
Since K = 25, we can find J with J = K + 5
J = K + 5
J = 25 + 5
J = 30
===
We find:
C (Chris) = 17 goals
K (Kieran) = 25 goals, and
J (Jermaine) = 30 goals
17 + 25 + 30 = 62 total goals.

-1 Is greater than -3/2, because -3/2 is -1.5 as a decimal which is less than -1.

What are mean, median and mode ?The three measures of central tendency used in statistics are mean, median, and mode. While describing a set of data, we always specify the focal point of any data set. The measure of central tendency is this. Every day, data are presented to us. We discover them in books, articles, bank statements, phone and utility bills, as well as in newspapers. There are so many; they are all around us. The challenge now is if we can identify some key characteristics of the data by focusing on only a few data points. The means, medians, and modes—measures of central tendency or averages—can be used to do this. When describing a set of data, a measure of central tendency locates the set's center.
