Answer:
Step-by-step explanation:
curved surface area is 2πrh, so 2*π*7*15.
7*15*2=210.
210*π=659.734
Answer:
Yes, this is surprising. Random samples with this much error are unusual.
Step-by-step explanation:
The expected proportion of green candies in the bag is p=0.20.
We have a sample with proportion p=0.3.
The amount of candies in the bag are 100.
We can calculate the probabilities of having 30 candies out of a sample of size n=100, if the proportion of the population is p=0.2.
This can be modeled by a binomial distribution with these parameters:
Then, the probability of having 30 or more candy in the bag is (applying the continuity factor):
There is too little probability (1%) of having 30 green candies in the bag.
You have the following equation:
11h - (2h -1) = 118
In order to solve for h the previous equation you proceed as follow:
11h - (2h -1) = 118
elminate parenthesis by takin into accoun the multilpication of signs
11h - 2h + 1 = 118 simplify similar terms and subtract 1 both sides
9h = 117 divide by 9 both sides
h = 117/9
h = 13
Hence, the solution to the given equation is h = 13
Answer:
$56.33
Step-by-step explanation:
30% off of $69.98 is ($49.99) then add 15% which makes it $56.33 .!
