Seventy-five percent of consumers prefer to purchase electronics online. You randomly select 8 consumers. Find the probability that the number of consumers who prefer to
purchase electronics online is (a) exactly five, (b) more than five, and (c) at most five.
(a) Find the probability that the number that prefer to purchase electronics online is exactly five.
P(5)=
(Round to three decimal places as needed.)
Using the binomial probability relation, the probability of the following events are :
P(x = 5) = 0.2076P(x > 5) = 0.6785P(x ≤ 5) = 0.3215Using the relation :
P(x = x) = nCx * p^x * q^(n-x)
Probability of success, p = 0.75q = 1 - p = 1 - 0.75 = 0.25Number of trials, n = 8Probability of exactly 5 :
P(x = 5) = 8C5 × 0.75^5 × 0.25^3
P(x = 5) = 0.2076
2.) Probability of selecting more than 5 :
P(x > 5) = p(6) + p(7) + p(8)
Using a binomial probability calculator :
P(x > 5) = 0.6785
3.)
Probability at most 5 :
P(x ≤ 5) = p(0) + p(1) + p(2) + p(3) + p(4) + p(5)
Using a binomial probability calculator :
P(x ≤ 5) = 0.3215
Therefore, the probability of selecting at most 5 is 0.3215

Find two consecutive odd integers such that
4 times the smaller integer is 19 less than 5
times the larger integer.
Answer:
9 and 11
Step-by-step explanation:
let the consecutive odd integers be n and n + 2 , then
4n = 5(n + 2) - 19 , that is
4n = 5n + 10 - 19 ( subtract 5n from both sides )
- n = - 9 ( multiply both sides by - 1 )
n = 9 and n + 2 = 9 + 2 = 11

Show that the equation x^3 + 6x - 5 = 0 has a solution between x = 0 and x=1
Answer:
Step-by-step explanation:
Solve the equation for 0 and 1:
x^3 + 6x -5
Replace x with 0:
0^3 + 6(0) -5 = -5
Replace x with 1:
1^3 + 6(1) -5 = 1+6 -5 = 2
Because the value of f(0) is negative and the value of f(1) is positive then there is at least one value of x between 0 and 1 that f(x) = 0

Brian painted 2/3 of a fence in 3/4 of a day. How long will it take him to paint the entire fence?
Answer:
9/8 days
Step-by-step explanation:
If it takes him 3/4 of a day to paint 2/3 of a fence, it would take him 9/8 days to paint the whole fence ((3/4)/(2/3)).
You can think of it like this:
It would take 3/8 of a day to paint 1/3 of a fence. So to find how long it takes to paint the whole fence, multiply 3/8 by 3.
if 1/3 of taffy cost $2.10 how much is one pound of taffy?

If the sum of a number and one is doubled, the result is six less than the number. Find the number.
Answer:
that would probably be 4
Step-by-step explanation:
the difference of a number and its absolute value.
Answer:
he sum of the first number and the square of the second number is 18. The difference between the square of the second number and twice the first number is 12.
I know the first set of equations would be x+y2=18 and y2−2x=12, and we can get x=2 and y=2 or y=−2.
My question is about how to understand difference when making equations. I know it means subtraction but would you ever use absolute values when making the equation?
For example, if I said the difference between a number x and 7 is 3, then wouldn't there be two answers? I would think of it as |x−7|=3 and then we could get two answers: x=10 and x=4. My rationale is that on the number line, the distance between either of my x values and 7 is 3.
In the quoted question I began with, then I could get the numbers of x=10 and y=22–√ or y=−22–√ but that's only if I did |y2−2x=12| and I don't feel that's right.

Explain how you can check that the value you found for g is correct. If your check does not work, does that mean that your result is incorrect? Explain. -----------------------------------------------------------------------------------------------------------------------------
Choose the correct explanation below.
A.
Substitute the value for g on one side of the equation to check the answer. If the check does not work, either the answer is incorrect or there were errors made when checking.
B.
Substitute the value for g on one side of the equation to check the answer. If the check does not work, then the answer must be incorrect.
C.
Substitute the value for g on both sides of the equation to check the answer. If the check does not work, either the answer is incorrect or there were errors made when checking.
D.
Substitute the value for g on both sides of the equation to check the answer. If the check does not work, then the answer must be incorrect.
The best explanation to given when checking for the value of g that you have found is:
C. Substitute the value for g on either sides of your equation to check the answer. If the check does not work, it is either the answer is incorrect or there were errors you made when checking.
After solving for a variable in an equation, we can cross check to know if our answer is correct or not.
This can be done by plugging in or substituting the value of the variable g into the equation. In most cases, you will find the variable on both sides.
When you substitute, the value on the left must be equal to the value on the right. If during your check, the value on the left does not equal the value on the right, it simply means the check does not work.
Two things might result to a check not working:
the answer is not correct, oryou made a mistake while checking.Therefore, the best explanation to given when checking for the value of g that you have found is:
C. Substitute the value for g on either sides of your equation to check the answer. If the check does not work, it is either the answer is incorrect or there were errors you made when checking.
