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.

f(x) = sqrt(2x); g(x) = sqrt(8x) Find (fg)(x) Assume x >= 0
The functions f(x) and g(x) combine to form a composite functions
The value of the composite function f(g(x)) is [tex]\sqrt{4\sqrt{2x}[/tex]
How to determine the function (fg)(x)The functions are given as:
[tex]f(x) = \sqrt{2x[/tex]
[tex]g(x) = \sqrt{8x[/tex]
To calculate (fg)(x), we have:
[tex]f(x) = \sqrt{2x[/tex]
This gives
[tex]f(g(x)) = \sqrt{2g(x))[/tex]
Substitute [tex]g(x) = \sqrt{8x[/tex]
[tex]f(g(x)) = \sqrt{2*\sqrt{8x}[/tex]
Simplify
[tex]f(g(x)) = \sqrt{4\sqrt{2x}[/tex]
Hence, the value of the composite function f(g(x)) is [tex]\sqrt{4\sqrt{2x}[/tex]

One angle be x
other is 2x-6ATQ
[tex]\\ \sf\longmapsto x+2x-6=90[/tex]
[tex]\\ \sf\longmapsto 3x-6=90[/tex]
[tex]\\ \sf\longmapsto 3x=96[/tex]
[tex]\\ \sf\longmapsto x=32[/tex]
[tex]\\ \sf\longmapsto 2x-6=2(32)-6=58°[/tex]
Answer:
58°
Step-by-step explanation:
The measure if one 2 complementary angle is 6 less than the measure of the other => x + 2x - 6° = 90°
x + 2x - 6° = 90°
3x = 90° + 6°
3x = 96°
x = 96° : 3
x = 32°
Substitution :
2x - 6°
= 2 × 32° - 6°
= 64° - 6°
= 58°

Find the value x
x=25 because 30+25=55. and 55-25=30
What are the values of x and y?
Answer:
D should be correct
Step-by-step explanation:
Lets create an equation.
7x + 1 + 4x - 8 + 120 + 12y = 360
We will now try all options to see which one fits perfectly.
----------------------------------------------------------------------------------
A) x = 3, y = 10
7(3) + 1 + 4(3) - 8 + 120 + 12(10) = 360
=> 21 + 1 + 12 - 8 + 120 + 120 = 360
=> 266 ≠ 360 (False)
----------------------------------------------------------------------------------
B) x = 1, y = 12
7(1) + 1 + 4(1) - 8 + 120 + 12(12) = 360
=> 7 + 1 + 4 - 8 + 120 + 144 = 360
=> 268 ≠ 360 (False)
----------------------------------------------------------------------------------
C) x = 32, y = 10
7(32) + 1 + 4(32) - 8 + 120 + 12(10) = 360
=> 224 + 1 + 128 - 8 + 120 + 120 = 360
=> 585 ≠ 360 (False)
----------------------------------------------------------------------------------
D) x = 17, y = 5
7(17) + 1 + 4(17) - 8 + 120 + 12(5) = 360
=> 119 + 1 + 68 - 8 + 120 + 60 = 360
=> 360 = 360 (True)
