Answer:
-10, -|-8|, -(-2), |-11|, 5²
Step-by-step explanation:
Well, it would end up to 3x=14 which is x=4.33
Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is
x - 30
Since the angles are a linear pair, theis sum is 180° , then
x +
x - 30 = 180, that is
x - 30 = 180 ( add 30 to both sides )
x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and
x - 30 =
(140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
Here,
n = 11
mean = 7
Standard Deviation (σ) = 3
S.E. = ?
We know that,
S.E. = σ/
S.E. = 3/
∴ S.E. = 0.905 Ans.
