S= 2 (LW) +2 (LH) +2(WH)
then we can plug in the values we know! :)
S= 2(2*3) +2(2*4) +2(3*4)
Then we can do some simplifying
S= 2(6) +2(8) +2(12)
Then some more multiplying...
S=12 +16 +24
Then lastly, addition
S= 52 cm^2
Answer:
You'd save $1.00
Step-by-step explanation:
Since both of the ice cream spots have an input of 2 then you'd just worry about the output (In this case $5.00 and $4.00) and since 5 - 4 = 1, you'd end up with 1 dollar left.... (I'm not sure if this was a real question or not but... yeah)
Answer:
0.8554 is the probability that the proportion of students living in dormitories is between 0.70 and 0.85
Step-by-step explanation:
We are given the following in the question:
Proportion of students who live in dormitories = 80%
Sample size, n = 80
Thus, the number of students follow a binomial distribution,
We use normal approximation to the binomial distribution to find the probability.
Parameters of Normal distribution:
We have to find the probability that the sample proportion (the proportion living in the dormitories) is between 0.70 and 0.85.
Thus, 0.8554 is the probability that the proportion of students living in dormitories is between 0.70 and 0.85
