The probability of getting a red card is 1/2 and the probability of getting a 10 is 4/52. To find the probability of getting both a red card and a 10, multiply the two.
(1/2)(4/52) = 4/104
4/104 = 1/26
Therefore, the probability is 1/26
Answer: 24.25
Step-by-step explanation:
The formula for calculating the area of a triangle given the apothem and perimeter is
Area = 
x apothem x perimeter
apothem = 2.16
perimeter = 22.45
substituting into the formula , we have
Area = x 2.16 x 22.45
Area = 24.246
Area≈ 24.25
Answer:
Given below
Step-by-step explanation:
First we state the objective of our research, whether what we have to find out.
Then we choose a random sample.
Then we collect the data about it, sort it and find out the statistics like mean etc.
The fourth step is to infer population parameters based on sample statistics.
The last step is to draw conclusions whether our objective is proved or not or what we can deduce from the results.
In this experiment the steps are as follows.
1) it is required to study how many hours households have internet usage.
2) The random sample in this experiment is 50000 households.
3) Finding out how many hours a day the household spends streaming video from the internet by asking from different households and then finding the mean etc.
4) The population mean prediction in this experiment depends on the sample mean.
5)The conclusion is drawn that how many hours a day the household spends streaming video from the internet.
Answer:
$25.30
Step-by-step explanation:
100% --- $22
