Answer:
A
Step-by-step explanation:
The angle adjacent to 133 and 133 form a straight angle and are supplementary, hence
adjacent angle = 180° - 133° = 47°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles. The angle 90 is an exterior angle, thus
p + 47 = 90 ( subtract 47 from both sides )
p = 43° → A
Answer:

Step-by-step explanation:
Well there are multiple different ways to write the equation of a line. The easiest way to do so in this situation would be to use point-slope form: (y-y_1)=m(x-x_1)
y_1 is the y coordinate of any point on the line, x_1 is the x-coordinate of the same point, and m is the slope. In this case it would look like (y-7)=3(x-5).
However, you might be required to answer in slope-intercept form. The equation of the line would then look like y=mx+b, where m is the slope, and b is the y-intercept. To solve for b we need to plug in the point (5,7) into the equation:
y=3x+b
(7)=3(5)+b
7=15+b
b=-8
Now plug b back into the initial equation and then you have your final, fully formed equation:
y=3x-8

Answer:</em></h3>
<em>mean = 4</em>
<em>Median = 3</em>
<em>Mode = 1</em>
Step-by-step explanation:
first let’s arrange the numbers from least to highest:
1 , 1 , 1 , 2 , 3 , 3 , 5 , 5 , 15
=====================
The median is the number that’s comes in the middle of the data set ⇒ median = 3 ( the fifth number in the data set)
1 , 1 , 1 , 2 , <u>3</u>, 3 , 5 , 5 , 15
________________________
The mode is the number that repeats the most ⇒ mode = 1 (repeated 3 times)

We can start with 364/1000. Then, after simplifying, you get the following:
182/500
91/250.
