Answer:

Step-by-step explanation:

Given: The mean of the temperatures in the chart is 24° and standard deviation is 4°.

To find: How many years had temperatures within one standard deviation of the mean

Solution: Mean temperature μ = 24 , standard deviation σ =4

The lower and upper bound for temperature within one standard deviation of the mean is given as:

Lower bound = μ - σ = 24 - 4=20

Thus, the Lower bound is = 20

Upper bound = μ + σ = 24+ 4=28

Thus, the Upper bound is = 28

Now, The temperature value between (Lower bound, Upper bound) that is (20, 28) is said to be within one standard deviation of the mean.

Hence 27° is the temperature value that is within one standard deviation of mean.

90 points please help!!!!!!!!
just olya [345]
To model this situation, we are going to use the exponential function: f(t)=P(1+ \frac{r}{n} )^{nt}
where
P is the initial number of cars
r is the growing rate in decimal form 
n is number of tames the growing rate is increasing per year
t is the time in years

To convert the growing rate to decimal form, we are going to divide the rate by 100%
r= \frac{12}{100}
r=0.12
Since the growing rate is increasing quarterly, n=4. We also know that the initial number of cars is 920, so P=920. Lets replace all those values in our function:
f(t)=920(1+ \frac{0.12}{4} )^{4t}
f(t)=920(1+0.03)^{4t}
f(t)=900(1.03)^{4t}

We can conclude that:
Rate ---------> The quarterly rate of growth is 0.03 or 3%
Exponent --------> The compound periods multiplied by the number of years                                 is 4t
Coefficient--------> The initial number of cars serviced is 920
Base------> The growth factor is represented by 1.03
