Ok, so
We got the following parallelogram:
We want to find the value of the angle BCD.
For this, remember that the sum of the internal angles of a parallelogram must be always equal to 360°.
So, we could write:
[tex]\begin{gathered} 2x+2x+x+x=360 \\ 6x=360 \\ x=\frac{360}{6} \\ x=60 \end{gathered}[/tex]The value of x is equal to 60°. Now, the angle BCD is an angle that measures 2x degrees.
So, BCD measures 2*60, which is 120°.
There are 150 people at an International Medical Conference. 40 are Africans, 70 are women and 110 are doctors. 12 of the women are Africans, 46 of the doctors are women and 31 of the Africans are doctors. If 5 of the African men are not doctors: a how many of the African women are doctors b how many of the men are neither African nor doctors?
Draw a Venn Diagram to visualize the situation:
Notice that the numbers in purple correspond to the total amount of people in the regions P and O, P and Q, P and S, respectively.
Numbers in red correspond to the number of people in each region.
Then, we should find the correct numbers for the regions O, P, Q and S, as well as M, N, R and T so that the total number of people in each group matches the labels.
Let x represent the amount of people in the region P.
Since the total amount of people in regions O and P must be 31, then the amount of people in O must be 31-x.
Similarly, the amount of people in region Q must be 12-x.
Since the amount of people in the region N (African men who are not doctors) is 5 and the total amount of African people is 40, then, we can write down an equation for x, where the sum of the amount of people in regions N, O, P and Q is 40:
[tex]5+(31-x)+x+(12-x)=40[/tex]Solve for x:
[tex]\begin{gathered} \Rightarrow5+31-x+x+12-x=40 \\ \Rightarrow48-x=40 \\ \therefore x=8 \end{gathered}[/tex]Notice that the number of people in region P, which is 8, corresponds to amount of African women who are doctors. Therefore, the answer for part a) is: 8.
To find how many of the men are neither African or doctors, find first the correct amount of people in regions R and T. This can be done by taking into account the total amount of people who are doctors and the total amount of people who are women.
The number of people in regions O, P, R and S must be equal to 110. For that to happen, the number of people in region R must be 41.
The amount of people in region T can be found similarly, and it is equal to 20.
Once the total amount of people in regions N, O, P, Q, R, S and T is known, we can deduce the number of people that must be in region M taking into account that the total amount of people in the conference is 150.
Substract the total amount of people in regions N to S (which is 139) from 150, in order to find the total amount of people in region M:
[tex]150-139=11[/tex]The region M corresponds to men who are neither African or doctors. Therefore, the answer to part b) is 11.

How did I get this wrong I need help with this problem ( please show work) P.s I don’t know what’s wrong with the quality
Answer:
a. 0.01%
b. 99.22°F
Explanation:
We know that the temperature follows a normal distribution with a mean of 98.18 °F and a standard deviation of 0.63 °F.
Part a.
If 100.6 °F is the lowest temperature that they consider fewer, we need to calculate the following probability
P( T > 100.6)
To calculate this probability, we first need to standardize 100.6 as follows
[tex]\begin{gathered} z=\frac{temp\text{ - mean}}{\text{ standard deviation}} \\ \\ z=\frac{100.6-98.18}{0.63}=3.84 \end{gathered}[/tex]Therefore, the probability is equivalent to
P(T > 100.6) = P(Z > 3.84)
Now, we need to use the table for positive z scores, but it gives the probability P (Z < z), so we can calculate P(Z > 3.84) as follows
P(Z > 3.84) = 1 - P(Z < 3.84)
P(Z > 3.84) = 1 - 0.9999
P(Z > 3.84) = 0.0001
Therefore, the percentage is 0.0001 x 100% = 0.01%. So 100.6 °F is appropiate because the probability that a healtly person is considered to have fewer is 0.01%
Part b.
If we want a temperature such that 5.0% exceed it, we need to find a value of z that satisfies
P(Z > z) = 0.05
P(Z < z) = 1 - 0.05
P(Z < z) = 0.95
Using the table, we get that z = 1.645. Then, we can find the temperature as follows
[tex]\begin{gathered} \text{ temp = z}\cdot\text{ \lparen standard deviation\rparen + mean} \\ \text{ temp = 1.645\lparen0.63\rparen+98.18} \\ \text{ temp = 1.036+98.18} \\ \text{ temp = 99.22 }\degree F \end{gathered}[/tex]Therefore, the answer for part b is 99.22°F

He then talks the dealer intogiving him 10% off. Fitzwilliam has also decided to put down a 25% downpayment on the car.Find Fitzwilliam's down payment on the car.Find the balance that Fitzwilliam needs to finance.
Given:
Sticker price of car = $10,000
His options will cost him extra 15% = 0.15
Percentage discount = 10% = 0.10
Down payment = 25% = 0.25
Let's solve for the following:
• (a). Find Fitzwilliam's down payment on the car.
Given that his options will cost him extra 15% and he got a percentage discount of 10%, the total amount he will pay for the car will be:
[tex]\begin{gathered} T=10000(1+(0.15-0.10)) \\ \\ T=10000(1+0.05) \\ \\ T=10000(1.05) \\ \\ T=10500 \end{gathered}[/tex]The total cost of the car will be $10,500
Now, to find the down payment, we have:
Down payment = 25% of Tottl cost
Down payment = 0.25 x 10500
Down payment =2625
Therefore, his down payment s $2625
• (,b). Find the balance that Fitzwilliam needs to finance.
To find the amount he needs t balance, apply the formula:
Balance = Total cost - down payment
Balance = 10500 - 2625

how do I find AC if AE = x + 50 and CE = x + 32
ANSWER
AC = 18
EXPLANATION
Let us draw a diagram to represent the situation:
From the diagram, we see that:
AC + CE = AE (since they are colinear)
So, we have that:
AC + x + 32 = x + 50
=> AC = x + 50 - x - 32
AC = 18
That is the value of AC.

how much time will it take for a fire to reach this machine size
Given the equation:
[tex]y=4(1.8){}^t[/tex]You know that "y" represents the number of acres of land, and "t" represents the number of minutes the fire has raged.
In order to find the time (in minutes) it will take for a fire to reach 160 acres, you need to substitute this value of "y" into the equation:
[tex]y=160[/tex]And then solve for "t":
[tex]160=4(1.8){}^t[/tex]Follow these steps in order to solve for "t":
- Divide both sides of the equation by 4:
[tex]\begin{gathered} \frac{160}{4}=\frac{4(1.8){}^t}{4} \\ \\ 40=(1.8)^t \end{gathered}[/tex]- Take the logarithm from both sides:
[tex]\begin{gathered} log(40)=log(1.8)^t \\ \\ log(40)=t\cdot log(1.8) \end{gathered}[/tex]- Divide both sides by the logarithm on the right side of the equation:
[tex]\begin{gathered} \frac{log(40)}{log(1.8)})=\frac{t\cdot log(1.8)}{log(1.8)} \\ \\ t\approx6.28 \end{gathered}[/tex]Hence, the answer is:

Linear FunctionA linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with y, this function can be written as y = 3x - 2.
In the relation, V = 4h. All we need to do is substitute the value of h into the formula and find v for that value of h.
When h = 2
v = 4h
v = 4 * 2 = 8cm³
When h = 6
v = 4 * 6 = 24cm³

determine whether the following graphs are functions using the vertical line test. what is the vertical line test?
The vertical line test is a method that is used to determine whether a given relation is a function or not. The approach is rather simple. Draw a vertical line cutting through the graph of the relation, and then observe the points of intersection.
The vertical line test supports the definition of a function. That is, every x-value of a function must be paired to a single yy-value. If we think of a vertical line as an infinite set of x-values, then intersecting the graph of a relation at exactly one point by a vertical line implies that a single x-value is only paired to a unique value of y.
If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.
If a vertical line intersects the graph in some places at more than one point, then the relation is NOT a function.
With the above illustration,
Graph 3 is not a function using vertical test because it has infinitely many solutions
Graph 4 is not a function because the vertical cuts the graph and intersect at a points
Graph 5 is a constant function because it has a repeated value of x and a constant y value
Graph 6 is not a function because the x-values which is the domain is repeated for different values of y
Graph 7 is not a function because the vertical line cuts the graph at two-point
Graph 8 is a function because it has one point intersection and each value of x have a corresponding value of y
