Answer:
68 degrees
Step-by-step explanation:
To get the interior angle, we use an important triangle principle
The principle is that the sum of the opposite interior angles equal the exterior angle
Let the second interior angle be x
x + 51 = 119
x = 119-51
x = 68
In this situation, you have:
The mode is 79 (that’s the most common number).
The median is 78.5 (the middle value or the average of the two middle values, since there is an even number of test scores).
The mean is less than both of those, as it was brought down by the few scores of 49.
The means the mean will be less than median.
Answer: C
Answer:
18.78
Step-by-step explanation:
x*(100%-8%)=17.28
x=18.78
Answer:
The probability is 1/6.
Step-by-step explanation:
If two line are perpendicular. The multiply of their slopes are equal to -1.
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope.
Let say second line's slope is m
m.-1/2=-1 so m=2
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true.
-2=4+b
b=-6
Thus,
y=2x-6 is true answer.
