Answer:
in steps
Step-by-step explanation:
12 - 6 x 2 + 3 = 3
(12 - 6 ÷ 2) x 3 = 27 .... ??
12 ÷ 6 + 2 x 3 = 8
12 ÷ 6 + 2 + 3 = 7
12 + 6 ÷ 2 + 3 = 18

Step-by-step explanation:
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.

The length of the segment ac is 10.3 cm
<h3>How to determine the length ac?</h3>
The segments are given s:
ab = 7.8cm
bc = 25mm
Point b is located between points a and c.
So, we have:
ac = ab + bc
Substitute known values
ac = 7.8cm + 25mm
Express mm a cm
ac = 7.8cm + 2.5cm
Evaluate the sum
ac = 10.3 cm
If the point b lies on segment ac, then there can be only one solution
