Find the measure of each missing angle
I’ll give BRAINLEST!!
Answer:
angle 4 = 115°[vertically opposite angles]
angle 2+ angle 4=180°[linear pair]
angle 2+ 115 = 180°
angle 2 = 180°-115°
angle 2=65°
angle1+angle2+80°=180°[sum of all angles is 180°]
angle1+65°+80°=180°
angle 1 + 140° = 180°
angle 1=180°-140°
angle1 =40°
angle2= angle5[vertically opposite angles]
angle7+angle5+61°+90°=360°[sum of all angles of quadrilateral is 360°]
angle7+ 65°+ 61° +90°=360°
angle7+ 211°=360°
angle7=360°-211°
angle7=149°
angle7+angle6=180°[linear equation]
149°+angle6=180°
angle6=180°-149°
angle6=31°
angle4+angle6+angle3= 180°[by sum of all angles is 180°]
115°+31+angle3=180°
146°+angle3=180°
angle3=180°-149°
anble3=41°

A newspaper collected information on schools in its circulation area in order to compare their quality. Two measures the newspaper collected for each school, mean class size and mean score on a statewide reading exam, are shown in the scatterplot. One school in the report, Springside Elementary, is labeled in the graph.
Which is a true statement regarding Springside?
Springside does not affect the correlation.
Springside weakens the correlation shown in the scatterplot.
Springside strengthens the correlation shown in the scatterplot.
Removing Springside would increase the value of the correlation coefficient.
Interpreting the scatterplot, it is found that the correct option is:
Springside weakens the correlation shown in the scatterplot.
In the scatterplot, the mean test score is plotted as function of the mean class-size.From this, we can verify that as the mean class size increases, the mean score decreases, that is, there is a negative correlation between the mean class size and the mean test score.However, for Springside, the mean test score is greater than most other schools with smaller class sizes, which is a different result than expected, thus, it weakens the correlation, and the correct option is:Springside weakens the correlation shown in the scatterplot.

write the equation of the graph in slope intercept form
(3,-3) (-3,-5)
m= -4
Answer:
y = -4x + 9
Step-by-step explanation:
Slope intercept form is:
y = mx + b
If m = -4
y = -4x + b
Plug the values of the first set of coordinates into this:
y = -4x + b
-3 = -4(3) + b
-3 = -12 + b
Add 12 to both sides of the equation to isolate b:
-3 + 12 = -12 + b + 12
9 = b
So that makes the slope intercept form:
y = -4x + 9

how to find the mean for negative numbers
You can find the mean of negative numbers just the same as for positive numbers. It doesn't hurt for the mean to be negative.
For example, with the number -9, -5, -4, -3, -1 you can find the mean jsut as any other numbers
-9+-5+-4+-3+-1=-22
-22/5=-4.4
the mean for those set of numbers is -4.4

Find the area
For height of garden we can use Phytagoreaan Theorem :
h² = 25² - 7²
h² = 625 - 49
h² = 576
h = 16 m
Area
= 1/2 × base × height
= 1/2 × 14 m × 16 m
= 7 m × 16 m
= 112 m²

4/5 of the money collected from a fundraiser was divided equally among 8 grades
What fraction did each grade receive?
Answer:
1/10
Step-by-step explanation:
your equation is 4/5 divided by 8/1.
Lets solve that problem with the acronym KCF, or
Keep
Change
Flip.
K: "keep" the first fraction, or the one you are multiplying with, so 4/5 stays the same.
C: "change" the division sign to a multiplication sign, so 4/5x8/1
F: "flip" the second fraction, so 8/1 becomes 1/8.
now our equation is 4/5x1/8. If we solve that, we get 4/40, which reduced is 1/10.
