Answer:
step 2
Step-by-step explanation:
72/8 does not equal 8. It equals 9
x=-11
we know that
Points A,B,C,and D are collinear and positioned in that order
so
AD=AB+BC+CD -----> by addition segment postulate
we have
AB=2x+30
AD=x=32
substitute the given values and solve for x
x+32 = (2x+43)
Group terms that contain the same variable
2x-x=32-43
x=-11
Y = 10x + 2. pls mark as brainliest
Answer:
<u>Use Two sided t-test</u>
<u>Step-by-step explanation:</u>
Note that, there are other tools to test for significant difference such as simple regression or multiple regression<em> but when comparing the results of two groups in terms of which is higher or lower</em>, then a two sided t-test would be best appropriate.
Since we want to know if there is a significant difference between the number of tornadoes in August and the number of tornadoes in October on average we use the two sided t-test because a Two sided t-test can show the possibility of positive or negative differences.
Answer:
y=1/3x-11
Step-by-step explanation:
Perpendicular to y=-3x
Get the negative reciprocal to find your new slope
1/3x is our new slope
y=mx+b
Plug coordinates in:
-2=-3(-3)+b
-2=9+b
b=-11
