2 . A
because acute angle is less then 90 degrees, and 90 degrees is a right angle, and anything above 90 degrees is obtuse .
Answer:
m + 5 = 10
m x 2 = 10
Step-by-step explanation:
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data below :
x : 89.3 68.6 32.7 37.3 39.7 46.7 66.1 79.4 66.4 52.1 47.3 64.4 53.7 63.4 46.2 63.0 92.1 57.6
Mean(m) = ΣX / n
ΣX = 1066 ; n = number of observations = 18
Mean(m) = 1066 / 18
Mean = 59.22
Standard deviation (σ) :
Using the online standard deviation calculator :
σ = √(Σ(x - m)²/n-1)
σ = √264.198395
σ = 16.72
The mean amount poured into a glass for the 18 samples is 59.22 while the variation in the data samples from the mean value is 16.72.
typical amount poured into a short, wide glass is 19.7 mL. A typical deviation from the mean amount poured is_____mL.
(59.22 - 19.7) mL = 39.52mL
Mean amount poured into a tall slender glass = 51.283
Mean (short wide glass) = 59.22mL
Mean (tall slender glass) = 51.283mL
Short wide glass > tall slender glass
Try it.
8 =? 2*8 - 4
8 =? 16 - 4
8 =? 12
8 is not a solution of the original equation
Try 4
4 = 2*4 - 4
4 = 8 - 4
4 = 4 and yes 4 works.
4 is unique. No other solution will work.
1/2 (1/16 + 1/12)
1/2 ((3 + 4 )/48)
1/2 × 7/48
= 7/96
