Answer:
Total weight = 111.6 lbs
Step-by-step explanation:
Given the following data;
Length = 1 feet
Width = 9.5 feet
Height = 13.5 feet
Mass of contents = 0.87 pounds per cubic foot
To find the weight of the contents in the container;
First of all, we would determine the volume of the rectangular prism;
Volume = length * width * height
Volume = 1 * 9.5 * 13.5
Volume = 128.25 cubic feet
Next, we find the overall weight;
Total weight = volume * mass of contents
Total weight = 128.25 * 0.87
Total weight = 111.6 lbs

The manager of a new supermarket wished to estimate the likely expenditure of his customers. A sample of till slips from a similar supermarket describing the weekly amount spent by 500 randomly selected customers was collected and analysed. This expenditure was found to be approximately normally distributed with a mean of $50 and a standard deviation of $15.
Find the probability that any shopper selected at random spends more than $80 per week?
Find the percentage of shoppers who are expected to spend between $30 and 80 per week?
Answer:
0.0228 = 2.28% probability that any shopper selected at random spends more than $80 per week.
88.54% of shoppers are expected to spend between $30 and 80 per week.
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Normally distributed with a mean of $50 and a standard deviation of $15.
This means that [tex]\mu = 50, \sigma = 15[/tex]
Find the probability that any shopper selected at random spends more than $80 per week?
This is 1 subtracted by the p-value of Z when X = 80. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{80 - 50}{15}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a p-value of 0.9772
1 - 0.9772 = 0.0228
0.0228 = 2.28% probability that any shopper selected at random spends more than $80 per week.
Find the percentage of shoppers who are expected to spend between $30 and 80 per week?
The proportion is the p-value of Z when X = 80 subtracted by the p-value of Z when X = 30.
X = 80
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{80 - 50}{15}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a p-value of 0.9772
X = 30
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{30 - 50}{15}[/tex]
[tex]Z = -1.33[/tex]
[tex]Z = -1.33[/tex] has a p-value of 0.0918
0.9772 - 0.0918 = 0.8854
0.8854*100% = 88.54%
88.54% of shoppers are expected to spend between $30 and 80 per week.

The teacher of a statistics class records the heights (in inches) of his students and draws a box-and-whisker plot to look over the data collected. This box-and-whisker plot shows theresult. (a) What is the median height? (b) What is the range of heights?
Answer:
a) Median Height = 66 inches
b) Range of Heights = 18 inches
Step-by-step explanation:
a) The median in a box-and-whisker plot is the second quartile, located between the first and third quartiles indicated by the dashed line. Therefore, the median height is 66 inches.
b) The range in a box-and-whisker plot uses the same process of finding the range of a set of data. You find the difference between the maximum and the minimum values of the data. Therefore, the range of heights is 77 - 59 = 18 inches.

If you deposit $2,000 into an account that pays 2% annual interest compounded monthly, how much money will be in the account in 5 years?
9514 1404 393
Answer:
$2,210.16
Step-by-step explanation:
The applicable formula for the account balance is ...
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years. Here, we have P=2000, r=0.02, n=12, t=5. The balance is ...
A = $2000(1 +0.02/12)^(12·5) = $2210.16

Alexander is building a rectangular pen in his backyard for his dog. The pen will have a length of 13 feet and a width of 2x feet.
4x+26
Step-by-step explanation:
to buy fencing, you need to find the perimeter of the pen. The perimeter is found by adding all sides together.
So, 13+13+2x+2x=4x+26
Write the equation of the line that passes through the points (1, -7) and (-6, -9).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.?
Answer:
y = 2/7 x - 51/7
Step-by-step explanation:
Equation of the line
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)
(y-(-7)/(-9-(-7) = (x-1)/(-6-1)
(y+7)/-2 = (x-1)/-7
(-y-7)/2 = (-x+1)/7
-y-7 = -2/7 x + 2/7
-y = -2/7x +2/7 + 7
y = 2/7 x - 2/7 - 7
y = 2/7 x + (-2-49)/7
y = 2/7 x - 51/7

Answer:
The independent is the weight of all the people already on the elevator and the dependent variable is the weight of the elevator after you get on.
Answer:
First fill in the blank answer - Dependent. Second fill in the blank - Indepenent
Step-by-step explanation:
So there are two different variables you need to know here:
The indenpenent variable - It is a variable that affects the dependent variable, however it can be changed in a experiment of project by the person.
The dependent variable - It is the variable that is affected by the independent variable, and varies throughout the expeirment.
In this case, the total weight after you get on depends on how heavy everyone else is before you get in the elevator.
This makes sense, because p cannot be changed, but with the addition of 132, effects the outcome, t.
So this means that the total wieght is the dependent variable.
The independent variable, on the other hand, changes to coutcome of how heavy to elevator is.
So this means the weight of the people in the elevator is the independent variable.
Hope this helps!

5. Sara thinks the following expressions are equivalent:
2x + 3 = x/2 + 3/4
Is she right? If so, prove that these two expressions are equivalent. If not, what error(s) did she make?
[tex]\sf\purple{No, \:Sara\: is \:wrong.}[/tex]
[tex]2x + 3≠ \frac{x}{2} + \frac{3}{4} [/tex]
[tex]\sf\red{Here's\:why:}[/tex]
[tex]L. H. S. = 2x + 3[/tex]
[tex]R. H. S = \frac{x}{2} + \frac{3}{4} \\ = \frac{x \times 2}{2 \times 2} + \frac{ 3}{4} \\ = \frac{2x + 3}{4} [/tex]
Clearly,
[tex]2x + 3≠ \frac{2x + 3}{4} \\✒ \: L.H.S.\:≠\:R. H. S. [/tex]
[tex]\boxed{Therefore,\:the\:two\:expressions \:are\:not\:equivalent.}[/tex]
To make them equivalent, Sara can simply divide L. H. S. by 4.
By doing so, she'll have
[tex] \frac{2x + 3}{4} = \frac{2x + 3}{4} \\ ๛L.H.S.=R. H. S[/tex]

Answer: The answer is A

0=0
The input is an identity: it is true for all values
Step-by-step explanation:
Answer:
D) Infinitely many solutions
Step-by-step explanation:
5x - 7x + 6 = -2(x - 3)
Distribute -2 on the right side of the equation:
5x - 7x + 6 = -2(x) + (- 2)(-3)
5x- 7x + 6 = -2x + 6
Combine like terms:
5x- 7x + 6 = -2x + 6
-2x + 6 = -2x + 6
-2x + 6 - 6 = -2x + 6 -6
-2x = -2x
-2x + 2x = -2x + 2x
0 = 0
This solution indicates that there are infinitely many solutions or all real numbers.

Step-by-step explanation:
"Slice" the rectangle into two right triangles (slice along the diagonal). Now you can use the Pythagorean theorem to calculate the length of the diagonal:
[tex]a^{2} +b^{2} =c^{2} \\12^{2}+15^{2} =c^{2} \\144+225=c^{2} \\\sqrt{369} =\sqrt{c^{2} }\\19.2m =c[/tex]
