Given: Mean temperature μ = 24 , standard deviation σ =4
The lower and upper bound for temperature within one standard deviation of the mean is given by,
Lower bound = μ - σ = 24 - 4
Lower bound = 20
Upper bound = μ + σ = 24+ 4
Upper bound = 28
The temperature value between (20, 28) is said to be within one standard deviation of the mean.
From given option 27° lies in between (20°, 28°), hence 27° is the temperature value that is within one standard deviation of mean.
18a: 3*3*3*2*a
20a: 2*2*5*a
6a: 3*2*a
the greatest common factor is 2a
Problem 1
<h3>Answer: choice B) They are supplementary angles</h3>
--------------
Explanation:
The two angles combine to form a straight angle (which is 180 degrees). Another term for these angles is "linear pair" since they form a straight line.
=================================================
Problem 2
<h3>Answer: choice B) x = 7</h3>
--------------
Explanation:
The diagonal is never used in this problem. For any rhombus, the four exterior sides are always the same length.
=================================================
Problem 3
<h3>Answer: Choice D) 62 degrees</h3>
----------------
Explanation:
We use the angle addition postulate. This allows us to combine angles BAC and CAD to form angle BAD.
(angle BAC)+(angle CAD) = angle BAD
30 + x = 92
x = 92-30
x = 62
angle CAD = 62
Answer:
Kamille paid $34.88 for her outfit after tax.
Ms. Roth will pay $59.16 in total.
Step-by-step explanation:
Kamille brought a new outfit that cost $32.00. The tax rate is 9%. How much did she pay for the outfit after tax?
32.00 x 0.09 = 2.88
32 + 2.88 = 34.88
Ms. Roth went to I-Hop for breakfast. She ordered pancakes for $5.00, eggs for $3.50, and orange juice for 42.50. if she tips the waiter 16%, how much will she pay in total?
5 + 3.5 + 42.50 = 51
51 x 0.16 = 8.16
51 + 8.16 = 59.16
Answer:
8
Step-by-step explanation:
6 x 9=54. 54+10=64. the square root of 64 = 8
