Okay so I'm guessing that they are two different formulas the f(x)= 3x and the f(x)= -5x-2. If that's is true then you would just have to plug in -2 to the x's. So then it would be f(x)= 3(-2) which if you solve it would give you f(x)= -6 and for the second one it would be f(x)= -5(-2)-2 so then you would solve for it and get f(x)= 8.
Answer:
126 customers
Step-by-step explanation:
90/500=0.18
that means that 18% of all customers were surveyed.
multiplying 700 by 0.18 yields 126, which is your answer!
p.s. this answer got deleted for some stupid reason so i reanswered it
4*2=8, 4-2=2, 2*9=18, 18+8= 26
26 is the answer
Hello,
f(1)=1=2^1-1
f(2)=3=2^2-1
f(3)=7=2^3-1
....
f(7)=127=2^7-1
f(15)=2^15-1=32767 (max of an integer coded on 16 bits)
There are 26 letters in the alphabet, 5 are vowels, therefore, the probability of choosing a vowel the first time is:
and the second time is:
Continuing with this reasoning, we get that the probabilities each time are:
Finally, the probability that you get all vowels is the product of the probabilities:
Writing the above result as a percentage we get:
