Answer:
34
Step-by-step explanation:
In PEMDAS, you do parenthesis first. So you do 14/2 (7) and 18+5 (23).
Now that the parenthesis are gone, adding is the only thing we can do, so you add 7, 23, and 4 to get 34.
Answer:
The value of k is -2
Step-by-step explanation:
The cut point with the y axis for both graphs occurs when x = 0
We have then:
For f (x):
The cut point with the y axis is:
For g (x):
The cut point with the y axis is:
Therefore, the value of k is given by the vertical displacement of the graph k units.
We have then:
From here, let's clear k:
I am not sure if this helped. But, I hope it did. I ma sorry if you get it wrong.
Hello!
Let's do this step by step!
We must convert 24/40 to a decimal before we can find out what percentage of 40 is 24.
To convert 24/40 to a decimal, we must multiply the numerator (24) by the denominator (40):
24 ÷ 40 = 0.6
Now that we have the decimal form, we will multiply the decimal by 100 to convert it to a percentage.
0.6 × 100 = 60
24/40 = 60%

If X is a random variable representing the number of children that end up having light-colored eyes, then X follows a binomial distribution with success probability p = 0.25 and number of trials n = 5.
The variance of a binomial distribution with these parameters is n p (1 - p), so the variance in this case would be
5 • 0.25 • (1 - 0.25) = 0.9375 ≈ 0.9
