Step-by-step explanation:
Circumference Formula: C = 2πr
Simply plug in r into the formula:
C = 2π(14)
C = 28π or 87.9646
Answer:
28π cm
Step-by-step explanation:
The circumference of a circle has the formula 2πr.
2 × π × r
Where r is the radius.
2 × π × 14
28 × π
= 28π
The circumference is 28π and the unit is centimeters.

For our particular data set, the value of the function f(x) is -2 when x = 0 (or f(0) = -2), and the value of x is 3 when f(x) = 27.
From the provided data, we see that we have specific values of x that correspond to certain values of the function f(x). Therefore, our goal is to find the value of f(x) when x = 0, and to find the value of x when f(x) = 27.
We start by finding the function value f(0). Looking at our data, we find an entry where x = 0, we observe that its corresponding f(x) value is -2. Thus, the value of the function f(x) is -2 when x = 0, so we have f(0) = -2.
Next, we're tasked with finding the value of x when f(x) = 27. To do this, we flip our perspective and look for entries in our data where f(x) = 27. After searching, we see an entry where f(x) equals to 27, and in this entry, the corresponding x value is 3. Therefore, when f(x) = 27, the value of x is 3.
In conclusion, for our particular data set, the value of the function f(x) is -2 when x = 0 (or f(0) = -2), and the value of x is 3 when f(x) = 27.

Answers
Answer:
Step-by-step explanation:
For "no fast food,
n1 = 9
Mean = (2310 + 2295 + 2280 + 2340 + 2235 + 2265 + 2315 + 2291.429 + 34.8466)/9
Mean, m1 = 2041
Standard deviation, s1 = √summation(x - u)²/n
summation(x - u)² =
(2310 - 2041)^2 + (2295 - 2041)^2 + (2280 - 2041)^2 + (2340 - 2041)^2 + (2235 - 2041)^2 + (2265 - 2041)^2 + (2315 - 2041)^2 + (2291.429 - 2041)^2 + (34.8466 - 2041)^2
= 4533653.14837256
s = √4533653.14837256/9
s = 709.75
For " fast food",
n2 = 10
Mean = (2579 + 2160 + 2165 + 2580 + 2558 + 2591 + 2614 + 2518 2583.125 + 33.0646)/10
Mean,m2 = 2238
summation(x - u)² =
(2579 - 2238)^2 + (2160 - 2238)^2 + (2165 - 2238)^2 + (2580 - 2238)^2 + (2558 - 2238)^2 + (2591 - 2238)^2 + (2614 - 2238)^2 + (2518 - 2238)^2 + (2583.125 - 2238)^2 + (33.0646 - 2238)^2
= 5672294.38379816
s2 = √5672294.38379816/10
s2 = 753.15
For a confidence interval of 95%, z = 1.96
The formula for confidence interval is
m1 - m2 ± z × √(s1²/n1 + s2²/n2)
= 2041 - 2238 ± 1.96 × √(709.75²/9 + 753.15²/10)
= - 197 ± 1.96 × √(55971.6736 + 56723.4923)
= - 197 ± 1.96 × 335.7
= - 197 ± 657.972
The lower end of the interval is
- 197 - 657.972 = - 854.972
The upper end of the interval is
- 197 + 657.972 = 460.972

Pablo is 12
Danny is younger than pablo by 1
12 - 1 = 11
Danny is 11
Terrell is younger than danny by 3
