Answer:
A) y = 4B) ∠A = 66°, ∠C = 114°, ∠D = 114°Step-by-step explanation:
Angles A and B, same as angles C and D are vertical angles and have equal measure according to definition of vertical angles:
Part Am∠A = m∠B = 66°6y + 42 = 666y = 66 - 426y = 24y = 24/6y = 4Part BFind the measure of angles C and D.
∠C and ∠D are supplementary with ∠A or ∠B, so the pair sums to 180°.
m∠C = m∠Dm∠A + m∠C = 18066 + m∠C = 180m∠C = 180 - 66m∠C = 114So the angle measures are:

(a) Josh would pay $592.48 for the television at the department store.
(b) Josh would pay $634.8 for the television at the superstore.
(c) Josh would pay less for the television at the department store.
Given:
Wholesale price of television = $529
(a) In the department store,
Television wholesale price is marked up by 40%.
Discount = 20%
Marked price = 529 × ( 1 + 40%)
= 529 × (140/100)
= $740.6
Selling price = 740.6 × (1 - 20%)
= 740.6 × (80/100)
= $592.48
(b) In the superstore,
Television wholesale price is marked up by 20%.
Marked price = 529 × ( 1 + 20%)
= 529 × (120/100)
= $634.8
He must pay the full in-store price.
Selling price = $634.8
Ignoring the tax, he must pay the full price at the superstore which is $634.8.
(c) As the selling price in the department store is less than in the superstore, $592.48 < $634.8.
So, Josh would pay less for the television at the department store.

A car manufacturer announced that next year the price of a certain model car would increase by 3.5%. This year the price is 15,757. Find the increase and the new price. The increase in the price of car is?The new price of car is?
Given:
Initial amount (Base) = 15, 757
Rate of increase = 3.5% or 0.035 in decimal form
Find: new price and the price increase
Solution:
To be able to get the new price, we need to solve for the price increase first. To do that, we need to know what is 3.5% of the old price 15, 757. To calculate that, we will multiply 0.035 by 15,757.
[tex]0.035\times15,757=551.495\approx551.50[/tex]3.5% of 15, 757 is 551.50. This is the price increase of the car next year.
Hence, by next year, the new price will now be 15,757 + 551.50 = 16, 308.50.

Considering the parameters of the normal distribution for American men's heights, it is found that:
a) The percentage greater than 74 inches is: 2.5%.
b) The proportion between 64 and 71.5 inches is: 0.815.
Normal DistributionThe z-score of a measure X of a variable that has mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by the following equation:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure represented by X is above or below the mean of the distribution, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X in the distribution.In the context of this problem, the mean and the standard deviation of the heights of American men are given as follows:
[tex]\mu = 69, \sigma = 2.5[/tex]
The proportion of heights that is greater than 74 inches is one subtracted by the p-value of Z when X = 74, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (74 - 69)/2.5
Z = 2.5
Z = 2.5 has a p-value of 0.9772.
1 - 0.9772 = 0.0228, hence the percentage is of 2.28%. Using the Empirical Rule, this percentage is rounded to 2.5%.
The proportion of heights between 64 inches and 71.5 inches is the p-value of Z when X = 71.5, subtracted by the p-value of Z when X = 64, hence:
X = 71.5:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (71.5 - 69)/2.5
Z = 1
Z = 1 has a p-value of 0.84. (rounded with the Empirical Rule).
X = 71.5:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (64 - 69)/2.5
Z = -2
Z = -2 has a p-value of 0.025. (rounded with the Empirical Rule).
Hence the proportion is:
0.84 - 0.025 = 0.815.

X' is the set of blood types that type AB- cannot donate blood to
Y is the set of blood types that type AB+ can donate blood to
From the table, AB- cannot donate blood to:
(This is all the blood types minus the ones that can receive from AB-)
U - {AB+, AB-} = {A+, B+, A-, B-, O+, O-} = X'
Y = {AB+}

You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 165 km south and 152 km east. Mt. Rainier is located approximately 56 km east and 40 km south of JBLM. If you are flying at a constant speed of 800 km/hr, how long after you depart JBLM will you be the closest to Mt. Rainier?
For the constant speed, it take 5 minutes 3 seconds after you depart JBLM will you be the closest to Mt. Rainier.
Speed:
Speed means a rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered.
Given,
You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 165 km south and 152 km east. Mt. Rainier is located approximately 56 km east and 40 km south of JBLM.
Here we need to find the time taken after you depart JBLM will you be the closest to Mt. Rainier for the constant speed of 800 km/hr.
Let us consider +x direction is east, and the -y direction is south.
We know that, JBLM is at the origin (0, 0). All distance units are presented in kilometers.
While we consider that, you are flying on line
165x + 152y = 0
We know that the slope of the line
ax + by = c
is given by -a/b, which suggests we can form the equation of a perpendicular line by swapping x and y coefficients and negating one of them.
Then, we get the equation as,
152x - 165y = c
That is perpendicular to the flight path.
Now we need to find c so that this is true at the coordinates of Mt. Rainier.
The perpendicular line through (56, -40) is
152x - 165y - (152(56) - 165(-40)) = 0
When we expand it then we get,
152x - 165y - (8512 + 6600 ) = 0
152x - 165y - 15112 = 0
We know that the distance in km from JBLM (0, 0) to this line is given by
So, when we apply the value of (x,y) as (0,0) then we get,
=> | 152(0) - 165(0) - 15112 |/√(152²+165²)
=> 15112/√50329
=> 15112/224.34
≈ 67.362
Therefore at the constant speed of 800 km/hr, you will have flown that 67. 362 km.
Then for one km you would take,
=> 62.076/800 hr ≈ 0.0842 hr
When we convert this then we get,
=> 0.0842 = 5 minutes 3 seconds.

Lauren used the Quantitative Reasoning Process to budget and to start a savings account. Each month she makes about $185 from a part-time job. Lauren's parents also send her $120 per month. The sum of Lauren's paycheck and the money she gets from her parents is 11% more than her total expenses. How much money does Lauren have available to add to her savings account each month?
Lauren can add $30 each month to her savings account
Income made by Lauren from part-time job = $185
Money sent to Lauren by her parents = $120
Total income of Lauren = Money from job+ money received from parents = 120+185 = $305
Let her total expenses be x
Substituting the values in the formula we get:
Sum of Lauren's paycheck + Money she gets from her parents = Total expenses+ 11% more than her total expenses
185 + 120 = x+11% of x
305=x+11/100*x
305 = 1.11x
x=274.77 or 275
Money she can add in her savings account each month = Total money received - Expenses = 305 - 275 = $30

The sum of the percentage of households that have the internet in 1997 and 2001 is approximately equal to the percentage of households that have the internet in 2009.
What is the meaning of each statement?Percentage is the fraction of an amount expressed as a number out of 100. In order to change a number to percentage, multiply the number by 100. The sign that represent percentage is %.
A function is an expression or rule that defines the relationship between the independent variable and the dependent variable. A function could be a linear function or an exponential function.
In this question,
x = is the number of years after 1980
and the independent variable is the percentage of households that use the internet after 1980.
H(27) = 61.7
1980 + 27 = 2007
This means that 61.7% households use the internet 27 years after 1980 or 61.7% households use the internet in 2007
H(4) = k
1980 + 4 = 1984
This means that k% households use the internet 4 years after 1980 or k% households use the internet in 194
H(37) > H(30)
This means that the percentage of households that use the internet 37 years after 1980 is greater than the percentage of households that use the internet 30 years after 1980

For each relation decide whether or not it’s a function(This is ONE question I do on my math program with this is considered one question)
Relation 1:
It is a function because one point of its range (axis y) have two points in the domain (axis x).
Relation 2:
It is not a function because one point in the domain have two points in the range:
Relation 3:
It is a function because each point in the domain have a different point in the range.
Relation 4:
It is not a function because the point -7 in the domain have three values for the range:
The answer is, the relations: 2,4 are not functions and the functions 1, 3 are functions.
3. Describe the similarities and differences among the following experiments. (a) Slips of paper are marked with the numbers 1, 2, 3, 4, and 5 and placed into a box. After being mixed, two slips are drawn simultaneously. (b) Slips of paper are marked with the numbers 1, 2, 3, 4, and 5 and placed into a box. After being mixed, one slip is drawn then put back into the box, then a second slip is drawn. (c) Slips of paper are marked with the numbers 1, 2, 3, 4, and 5 and placed into a box. After being mixed, one slip is drawn and not put back into the box, then a second slip is drawn.
SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Describe the first experiment
Two slips were drawn simultaneously, this means that the outcome of the first slip drawn will be multiplied by the outcome of the second slip drawn. The probability will follow the "and rule of probability".
STEP 2: Describe the second experiment
Since one slip is drawn and then put back into the box before a second slip is drawn, this is a PROBABILITY WITH REPLACEMENT. The outcome of the first event will not affect the outcome of the second event since the paper slips are replaced hence not reduced.
STEP 3: Describe the third experiment
Since one slip is drawn and not put back into the box before a second slip is drawn, this is a PROBABILITY WITHOUT REPLACEMENT. The outcome of the first event will affect the outcome of the second event since the paper slips reduce.
Difference between b and c is that b is with replacement and the total outcomes does not change while c is without replacement and the total outcomes change(reduce) after the first slip is drawn.
