Answer:
The definition of alternate interior angles is that those two angles are the same.
Therefore because they are the same you can set them equal to eachother
3x + 24 = 78 is true
3x = 54
x = 18
Just know the definitions, for instance 3 and 4 are the same, 2 and 5 are the same, 1 and 6 are the same

2/(p+1)- 1/(p+1)+4/(1-p^2)
Answer:
(5-p)/(p+1) (1-p)
Step-by-step explanation:
2/(p+1) -1/(p+1)+4/(1+p)(1-p)
{2(1-p)-(1-p)+4}/( p+1) (1-p)
on solving we get
(5-p)/(p+1 )(1-p)
This figure represents a large storage container that will be built out of a new durable material. The storage company needs 8 of these containers.
How much of the new material is needed to build all 8 containers?
Enter your answer in the box.
ft²
Right pentagonal prism. The height of the prism is 8 ft. The base has two pairs of parallel sides. The sides are consecutively labeled 5 ft, 3 ft, 5 ft, 2 ft, and 7 ft. The parallel sides are those labeled 3 ft and 7 ft, and 5 ft and 2 ft.
The amount of material needed for the containers is its surface area
The amount of material needed for the 8 containers using the assumed parameters is 3080 square feet
How to determine the amount of material?The question is incomplete, as the figure of the right pentagonal prism is not given.
So, I will provide a general explanation.
The surface area (SA) of a right pentagonal prism is:
SA = 5b(a + h)
Where:
b represents the base lengtha represents the apothemh represents the heightFrom the question, we have the height of the prism to be 8 ft.
Assume that:
a = 3 ft and b = 7 ft
The equation becomes
SA = 5 * 7 * (3 + 8)
Evaluate the product
SA = 385
The amount of material needed for the 8 containers would be:
Amount = 8 * 385 square feet
Amount = 3080 square feet
Hence, the amount of material needed for the 8 containers using the assumed parameters is 3080 square feet

Which product range generated the most profit over all???
Answer:
Blue label
Step-by-step explanation:
All that matters here is # of bottles sold * profit per bottle.
If you multiply these 2 values for each row you will see the blue label has the highest amount of profit.
Among all the product ranges blue label generated the most profit of $5625.
What is profit?Profit is basically the difference between the total revenue and the total cost of the product.
Profit=Total Revenue- Total cost.
How to calculate profit?We know that Average profit= total profit/ number of units.
So the profit will be as average profits* number of units.
So the profit of product ranges will be =average profit * number of bottles.
Profit of red label=1.12*3000
=$3360
Profit of black label=1.5*2000
=$3000.
Profit of gold label=2.75*1000
=$2750
Profit of white label=1.20*2750
=$3300
Profit of blue label=2.25*2500
=$5625.
Hence among all the product ranges blue label has generated maximum profit.

Which statement is true about every exterior angle of any quadrilateral inscribed in a circle?
The measure of an exterior angle is equal to the measure of the nonadjacent interior angle.
The measure of an exterior angle is equal to the measure of an adjacent interior angle.
The measure of an exterior angle is equal to the average of the measures of the two adjacent interior angles.
The measure of an exterior angle is equal to the difference of the measures of the two adjacent interior angles.
Answer:
A
Step-by-step explanation:
In an inscribed quadrilateral, opposite angles are supplementary.
An exterior angle of a quadrilateral is supplementary to the adjacent interior angle.
Since the exterior angle is supplementary to both the adjacent interior angle and to the opposite interior angle, the exterior angle and the opposite interior angle are congruent.

According to the Mars company, packages of milk chocolate M&Ms contain 20% orange candies. Find the probability that in a random sample of 100 M&M candies, there are between 18% and 22% orange candies.
Using the normal distribution, it is found that there is a 0.383 = 38.3% probability that the sample proportion is between 18% and 22%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].In this problem, the proportion and the sample size are of p = 0.2 and n = 100, respectively, hence:
[tex]\mu = p = 0.2[/tex]
[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.2(0.8)}{100}} = 0.04[/tex]
The probability that in a random sample of 100 M&M candies, there are between 18% and 22% orange candies is the p-value of Z when X = 0.22 subtracted by the p-value of Z when X = 0.18, hence:
X = 0.22:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.22 - 0.2}{0.04}[/tex]
Z = 0.5
Z = 0.5 has a p-value of 0.6915.
X = 0.18:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.18 - 0.2}{0.04}[/tex]
Z = -0.5
Z = -0.5 has a p-value of 0.3085.
0.6915 - 0.3085 = 0.383.
0.383 = 38.3% probability that the sample proportion is between 18% and 22%.

Answer:
The z-test statistic for a hypothesis test in which the null hypothesis states that the population proportion, p, equals 0.14 if the following sample information is present (n = 200; x = 31) is z = .6114.
Step-by-step explanation:
The z-test statistic formula is:
[tex]\displaystyle z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]We are given x = 31 and n = 200, so we can solve for [tex]\hat{p}[/tex] : 31/200 = .155.
The population proportion, [tex]p=.14[/tex], is given in the problem.
We can substitute the known values into the z test statistic formula:
[tex]\displaystyle z = \frac{.155-.14}{\sqrt{\frac{.14(.86)}{200} } }[/tex][tex]\displaystyle z=\frac{.015}{\sqrt {.000602}}[/tex][tex]z=.6114[/tex]The z-test statistic for this problem is z = .6114.

Nancy put new insulation in her attic and discovered that her heating bill for December decreased from $160 to $100. What is the percent decrease?
The amount of decrease is ______?
Answer:
37.5% decrease
Step-by-step explanation:
To find a relative percentage you generally follow the rule of part divided by whole.
$100 / $160 = .625 (62.5%)
So $100 is 62.5% of $160
To find the decrease we need to subtract 62.5% from 100%
100 - 62.5 = 37.5
future value of 10% savings from earnings of 36000 earns 6.25% annual interest compounded quarterly for 15 years
without further ado
10% of 36000 is simply 3600, we chopped a "0" off of it hmmm, ok so
