Answer: Width = 6m
Working:
Find common factors of 72:
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Work out which ones multiply together to make 72 and as the question states that the length is twice the width, we need to find two numbers that multiply to make 72 and one of the numbers is double the other number.
These numbers would be 6 and 12. (6 x 12 = 72)
Therefore:
Area = 72m²
Width = 6m
Length = 12m
Answer:
P(X = 2) = 0.27894
Step-by-step explanation:
Given:
- The probability that no vision correction is required p = 0.23
- No. adults are randomly selected n = 6
Find:
- P ( Exactly 2 dont require vision correction)
Solution:
- We will declare a random variable X is the umber of adults out of 6 that do not require vision correction. X follows a Binomial distribution:
X~ B ( 6 , 0.23 )
- The probability required is P ( X = 2 )
- Using the pmf of binomial distribution we have:
P(X = 2) = 6C2 * (0.23)^2 * (0.77)^4
P(X = 2) = 15 * 0.0529 * 0.35153041
P(X = 2) = 0.27894
Answer:
equilateral
Step-by-step explanation:
because all sides are equal
The correct choice is A. When something is being increased by a percentage, you add the percentage to 100%, so you add 35% to 100% to make a decimal of 1.35. Every year the initial value of 590 will be increased by 35%. so the correct choice is A.
Answer: $169,500
Step-by-step explanation:
The mean simply means the average price of a set of a numbers that are given. For one t calculate the mean, one has to add the numbers that are given and then divide them by the amount of numbers.
I'm the case above, the numbers given are $165,000, $188,000, $175,000, and $150,000.
Mean = ($165,000 ,+ $188,000 +$175,000 + $150,000) ÷ 4
= $678,000/4
= $169,500
