Answer:
Step-by-step explanation:
a)
P(f ) = probability of being female = .3
P(m ) Probability of being male = .7
P(s/m) = probability of having a smoker worker given that he is a male = .6
P(s/f) = probability of having a smoker worker given that he is a male = .4
p(s) = p(m) x p(s/m) + p(f) x P(s/f)
= .7 x .6 + .4 x .3
= .42 + .12
= .54
b )
p (m/s) = probability that this person will be a male,Given that this person is a smoker
p(m) x p(s/m) / [ p(m) x p(s/m) + p(f) x P(s/f) ]
= .7 x .6 / .7 x .6 + .4 x .3
= .42 / .54
= .78
c )
Probability of the person being a smoker and male
= .54 x .78 = .42
probability of a person being a male and non smoker = .7 - .42 = .28
probability of a person being a non smoker and female = .46 -.28 =.18
probability that person will be a smoker or a male
= 1 - (a person being a non smoker and female).
= 1 - .18
= .82 .
This question is Incomplete because it lacks the appropriate diagram for the square pyramid. Please kindly find attached the required diagram
Answer:
45 square inches
Step-by-step explanation:
From the question, we are told that the foil covers the body of the trophy including the bottom, hence the formula we would be applying =
Total Surface Area of the Square pyramid = 2bs + b²
Where s = Height of the square pyramid
b = Edge length of the square pyramid
From the attached diagram, we can see that:
s = 6 inches
b = 3 inches
Total Surface Area of the Square pyramid = 2bs + b²
= 2 × 3 × 6 + 3²
= 36 + 9
= 45 square inches.
Therefore, the amount of gold foil it took to cover the trophy, including the bottom is 45 square inches
Answer:
What is w equal to?
Step-by-step explanation:
First you need to find out how much Molly paid. So, $24 times 0.25 equals $6 off so $24 minus $6 equals $18. Molly paid $18 for the jeans. Then to find the percentage of increase you would find the difference between how much the store bought the jeans minus how much they sold them for which is $18-$6=$12 then u would do $12 divided by $6 which is 2 and then multiply by 100 to get 200%. So the store earned a 200% increase on the jeans they sold to Molly.
