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.
Answer:

Step-by-step explanation:
we have

solve for x

Group terms that contain the same variable and move the constants to the other side



Answer:

Step-by-step explanation:
Equation to remember:
where t = time
= 1200 since that's the initial population
= .35 rate of change \\
= 5 years
Plug in the numbers;

Since the prompt looks like it's asking for an equation given any number of years.. then just change 5 to n for number of years.

X would equal 8 and y would equal -7
Answer:
1/2
Step-by-step explanation:
from one point to another it goes up 1 and over two. so rise over run, 1 over 2
