Y=1/2x-4
Perpendicular means it is opposite and the reciprocal. 1/2(4) = 2-4 equals -2.
(4,-2)
Answer:
Step-by-step explanation:
Given that the linear correlation coefficient r is found to be 0.591
the critical values are r equals plus or minus 0.878.
Significance level used = 0.05
The correlation r = 0.591
(two tailed test)
Test statistic =
Since r is less than 0.878, we accept that there is linear correlation between the two variables.
(4)2 + 7= 15.
15-7=8.
I would say that number is 4 because 4+4= 8, and 8+7 =15.

Answer:
127.1 m
Step-by-step explanation:
We are given the value of the adjacent side and we are to find the value of the opposite side
Tan would be used to determine this value
Tan 23 = opposite / adjacent
1.5882 = x / 80
x = 80 x 1.5882
x = 127.056 m
x = 127.1m
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
