Is this the right answer?
Area =lw
=2x (8+1)
=2x (9)
=18x
therefore the area is 18x
66,80,35,24000
Those are the answers if I’m correct
Answer:
a. 0.6588
b. 0.3978
c. 0. 279
Step-by-step explanation:
In the given question the success and failure are given the number of outcomes is fixed so binomial distribution can be applied.
Here success= p = 12 % or 12/100 = 0.12
failure = q= 1-p = 1-0.12 = 0.88
n= 10
Using binomial probability distribution
a. Probability that the number of selected adults saying they were too young is 0 or 1 is calculated as:
P (x=0,1) = 0.12 ⁰(0.88)¹⁰10 C0 + 0.12 (0.88)⁹ 10 C1= 1* 0.279 * 1 + 0.12 ( 0.3165) 10 = 0. 279 + 0.3978= 0.6588
b. Probability that exactly one of the selected adults says that he or she was too young to get tattoos is calculated as
P (x=1) = 0.12 (0.88)⁹ 10 C1= 0.12 ( 0.3165) 10 = 0.3978
c. Probability that none of the selected adults say that they were too young to get tattoos is
P (x=0) = 0.12 ⁰(0.88)¹⁰10 C0 = 1* 0.279 * 1 = 0. 279
Step-by-step explanation:
A.) Ok, so the mean price for Southtown is 72,800.
And the mean price for middle town is 54,900
So Southtown has the higher mean price.
Explanation:
To find the mean. You must first add up all the numbers, then divide the total by how many numbers you added up.
72,000 + 50,000 + 68,000 + 93,000 + 81,000 = 364,000
Then,
364,000/ 5 = 72,800
B.) It is 17,900
Explanation:
72,800 - 54,900 = 17,900
Hope this helps you out!!! : )
