Answer:
{(1,4) (2,8) (3,12) (4,16)}
The statement is always true because right angles measure 90 degrees and if you add them you get 180 and supplementary angles are angles that add up to 180.
Hope this helps :)
I think u do 3•5 then divide by 110
Answer:
The margin of error at 90% confidence is 0.5133 gram.
Step-by-step explanation:
Margin of error (E) = (critical value × sample standard deviation) ÷ sqrt(n)
sample standard deviation = 1.5 grams
confidence level = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
n (sample size) = 25
degree of freedom = n - 1 = 25 - 1 = 24
critical value (t) corresponding to 24 degrees of freedom and 10% significance level is 1.711
E = (1.711×1.5) ÷ sqrt(25) = 2.5665 ÷ 5 = 0.5133 gram
J = 3S + 2
S = J - 14
S = 3S + 2 - 14
S - 3S = 2 - 14
-2S = - 12
S = -12/-2
S = 6
J = 3S + 2
J = 3(6) + 2
J = 18 + 2
J = 20
and the difference is : 20 - 6 = 14 <===
