Electricity bills: According to a government energy agency, the mean monthly household electricity bill in the United States in 2011 was $109.55. Assume the amounts are normally distributed with standard deviation $21.00. Use the TI-84 Plus calculator to answer the following. (a) What proportion of bills are greater than $135? (b) What proportion of bills are between $84 and $143? (c) What is the probability that a randomly selected household had a monthly bill less than $119? Round the answers to at least four decimal places.
Answer:
a) 0.11277
b) 0.83253
c) 0.67364
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
From the question,
Mean = $109.55.
Standard deviation = $21.00.
a) What proportion of bills are greater than $135?
z = (x-μ)/σ
z = 135 - 109.55/21
= 1.2119
Probability value from Z-Table:
P(x<135) = 0.88723
P(x>135) = 1 - P(x<135) = 0.11277
The proportion of bills are greater than $135 = 0.11277
(b) What proportion of bills are between $84 and $143?
For x = $84
z = (x-μ)/σ
z = 84 - 109.55/21
= -1.21667
Probability value from Z-Table:
P(x = 84) = 0.11187
For x = 143
z = (x-μ)/σ
z = 143 - 109.55/21
= 1.59286
Probability value from Z-Table:
P(x = 143) = 0.9444
The proportion of bills are between $84 and $143
= P(x = $143) - P(x = 84)
= 0.9444 - 0.11187
= 0.83253
(c) What is the probability that a randomly selected household had a monthly bill less than $119?
For x = $119
=119 - 109.55/ 21
= 0.45
Probability value from Z-Table:
P(x<119) = 0.67364
The probability that a randomly selected household had a monthly bill less than $119 is 0.67364

Allie must sell at least 50 gift baskets for the band fund-raiser. She already sold 36 baskets. Write and solve an inequality to determine how many more baskets Allie must sell for the fund-raiser.
Answer:
36+x>=50
I might be wrong but here's my explanation.
Step-by-step explanation:
We first of all know that she MUST sell 50 or more baskets.
Knowing this, we know the inequality sign will be facing the x and the 36 as the baskets can be equal to 50 or greater than 50.
Now we have: 36+x>=50
The x is remaining baskets needed.
If you were to solve the inequality you would get x>=14
Hope this helps! P.s. I'd do a bit more research just in case I'm wrong!! :)

Answer:
P1P2 = P1P3 = 2√2P2P3 = 4isosceles right triangle (both)Step-by-step explanation:
The length of a side can be found using the distance formula:
d = √((x2 -x1)^2 +(y2 -y2)^2)
For P1P2, this gives ...
d = √((0-(-2))^2 +(1-(-1))^2) = √(4+4) = √8
P1P2 = 2√2
__
The same ∆x and ∆y apply to P1P3, so we know ...
P1P3 = 2√2
__
The lengths of P1P2 and P1P3 are the same, so the triangle is isosceles.
__
The length of P2P3 can be found by subtracting the y-coordinates:
P2P3 = 1 -(-3)
P2P3 = 4
__
We note that the slope of P1P2 is 2/2 = 1, and the slope of P1P3 is -2/2 = -1. The product of these slopes is (1)(-1) = -1, so we know those lines are perpendicular. The triangle is a right triangle.

Solve this equation, and show work. worth 40 points.
Answer:
[tex]b=-3[/tex]
Step-by-step explanation:
We have:
[tex]25^b\cdot 125^{b+2}=125^b[/tex]
Notice that 125 is the same as 5³. So:
[tex]25^b\cdot ((5)^3)^{b+2}=((5)^3)^b[/tex]
Also, 25 is the same as 5². So:
[tex]((5)^2)^b\cdot ((5)^3)^{b+2}=((5)^3)^b[/tex]
Power of a power property:
[tex]5^{2b}\cdot 5^{3(b+2)}=5^{3b}[/tex]
Power of a product property:
[tex]5^{2b+3(b+2)}=5^{3b}[/tex]
Since they have the same base, the exponents are equal. So:
[tex]2b+3(b+2)=3b[/tex]
Solve for b. Distribute on the left:
[tex]2b+3b+6=3b[/tex]
Combine like terms on the left:
[tex]5b+6=3b[/tex]
Subtract 5b from both sides:
[tex]6=-2b[/tex]
Divide both sides by -2. So, the value of b is:
[tex]b=-3[/tex]
And we're done!
Is 835% less than 0.95
Answer:
no, 835% is not less than 0.95.
Step-by-step explanation:
as a percentage, 0.95 is 95%. 835% is greater than 95%. hope this helps.
Answer:
No
Step-by-step explanation:
835% as a decimal would be 8.35 and 0.95 is what you are comparing it to, so you could look at it's whole number and you see that it is bigger than zero so it is indubitably more than 0.95.

You are certain to get 2 Kings when selecting 50 cards from a shuffled deck. express the indicated degree of likelihood as a probability value between zero and one inclusive
Answer:
1
Step-by-step explanation:
The probability of this happening would be a 1 when placing a value between zero and one inclusive. One in this case would indicate a 100% probability. This is the case because in the question it is stated that it is "certain" that you will get 2 kings when selecting 50 cards, this means that no matter what it will happen every time 50 cards are drawn, thus making the probability 100%. If the question were phrased differently such as "what is the probability of getting 2 kings from 50 cards drawn?" then the probability would be 0.04 or 4% which is 2/50.
Using probability concepts, it is found that the likelihood is of 1.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
A few observations regarding probabilities are important.
It assumes values between 0% and 100% as percentages and between 0 and 1 as decimals.If an event is certain not to happen, the probability is of 0% = 0.If an event is certain to happen, the probability is of 100% = 1.In this problem, you are certain to get 2 Kings when selecting 50 cards from a shuffled deck, hence the likelihood is of 1.

Brian bought a fish tank that is 22 in. long, 12 in. wide, and 16 in. tall. Which is the volume of the fish tank?
Answer: 4224 feet cubed
Step-by-step explanation:
Volume for a rectangular tank =LxWxH
22x12x16=4,224
Answer:
4224in^3
Step-by-step explanation:
The formula for volume is height x length x width ( x means multiply)
so to find the volume of the fish tank you multiply each of the sides by each other, 12x16x22. So the volume of the fishtank is 4224 inches cubed(^3) make sure you write the cubed and units at the end, just like how for area you always make it squared.
A linear function and a quadratic function both have a domain of all real numbers.
True
False
?
Answer: True
Explanation: The domain of a quadratic function in standard format is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.
Linear function is almost always going to be all real numbers. The range of a non-horizontal linear function is all real numbers no matter how flat the slope might look.

Suppose our retirement account pays 9% apr compounded monthly; what size nest egg do we need in order to retire with 25 years that yields to $5,000 per month? Show all work
Answer:
$595,808.11
Step-by-step explanation:
We assume the retirement account is intended to pay out $5000 per month for 25 years. The amortization formula can be used to find the required amount. The monthly payment A based on principal P with interest at annual rate r for t years satisfies the relation ...
A = P(r/12)/(1 -(1 +r/12)^(-rt))
P = A(12/r)(1 -(1 +r/12)^(-rt))
P = 5000(12/0.09)(1 -(1 +.09/12)^-300)
P = $595,808.11
The required nest egg is $595,808.11.
