Answer:
Step-by-step explanation:
Split the triangle into a 30-60-90 triangle. Since you have LM from that triangle, you can figure out the other sides. Then, using the leg from that triangle, the one next to it is a 45-45-90 triangle, meaning it's isosceles.
KM = 30 + 10√3
KL = 10√6
Answer:
2.5% probability that a randomly selected book has fewer than 133 pages.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 189 pages
Standard deviation = 28 pages
What is the probability that a randomly selected book has fewer than 133 pages?
133 = 189 - 2*28
So 133 is two standard deviations below the mean.
The Empirical Rule states that 95% of the measures are within 2 standard deviations of the mean. The other 5% is more than two standard deviations distant from the mean. The normal distribution is symmetric, which means that of those 5%, 2.5% are more than 2 standard deviations below the mean and 2.5% are more than 2 standard deviations above the mean.
This means that there is a 2.5% probability that a randomly selected book has fewer than 133 pages.

Hello! answer: a = 11
Step-by-step explanation:
2 × 11 = 22 So therefore a = 11 HOPE THAT HELPS!
Answer:
(f/g)(x) = x³ - 7x + 2
(f/g)(2) = -4
Step-by-step explanation:
To find (f/g)(x), divide f(x) by g(x). The process is shown in the attached image.
(f/g)(x) = x³ - 7x + 2
To find (f/g)(2), plug in 2 wherever there is an x.
(f/g)(x) = x³ - 7x + 2
(f/g)(2) = (2)³ - 7(2) + 2
(f/g)(2) = 8 - 14 + 2
(f/g)(2) = -6 + 2
(f/g)(2) = -4
Answer:
60 people
Step-by-step explanation: Multiply 20 by 3 and you will get 60, which is the total combonation of people.
