Answer:
Median: 8
Minimum: 3
Maximum: 15
First quartile: 6
Third quartile: 12.5

Outliers: none
Step-by-step explanation:
Answer:
130
Step-by-step explanation:
X is the alternate corresponding angle to 50. 50+y=180
y=130
x and y = the same thing so 130 is the value of x
Answer:
D
Step-by-step explanation:
Mean tells us the average (in this case, total marks/ total number of students).
Standard deviation tells us the spread of a set of data from its mean (how much it deviates from the mean).
Thus, standard deviation can be used to determine the consistency of a data. <u>The smaller the standard deviation, the more consistent the data is</u>.
Since 4S has the smallest standard deviation of 1, it shows the most consistent achievement in the test.
if its 45 miles per hour then, 0.75 mile/minute.
The required equation of line B is 2y+5x=-2
The equation of a line in point-slope form is expressed as:
y-y0 = m(x-x0)
m is the slope of the line
(x0, y0) is the point on the line
Given the line A expressed as:
2x = 5y – 25
Rewrite in standard form
5y = 2x + 25
y = 2/5 x + 5
The slope will be 2/5
The slope of the perpendicular line will be;

Substitute the point (-6, 14) and slope -5/2 into the equation above to get the required equation of line B

Hence the required equation of line B is 2y+5x=-2
