Answer:
a. The probability that 359 or more of 1487 adults sleepwalked is zero (0).
b. Yes, it's significantly higher than the 21.6% of people who sleepwalked.
c. The result suggests 321 adults.
Step-by-step explanation:
a. The assumed 359 sleepwalked adults exceed the 21.6% correct rate. 359 sleepwalked adults give 24.1%.
b. Yes, it is significantly high because it's 24.1% instead of correctly assumed 21.6%.
c. 21.6% sleepwalked adults give 321.2 people. Hence, people can only be in whole of numbers. Therefore, it is 321 adults.
Answer:
7.8025
Step-by-step explanation:
You get the circumfence formula 2 * pi * r
since you are looking for the radius divide 49/2 then the answer you get divide it by pi and then you have your radius

Answer:
r=s+5
Step-by-step explanation:
So, letsgo over what we know:
The regular price is r
The sale price is s
Now lets compare the difference between r and s:
10r = 5s
20r = 15s
30r = 25s
What is the difference between the r and s value in each situration?
Well, from what I can see, r is always 5 more than s.
This can be writen as:
r = s+5\
So this is our equation, for if you plug in any number for s, you will get an accurate r value.
For instance, if you say s is 25:
r=25+5
=
r=30
This looks just like the 30r=25s in the table above.
So:
r=s+5

The square of half the x-coefficient must be added. That value is
... ((1/2)·(-3/4))² = (-3/8)² =
