Step-by-step explanation:
1) ?
I can't see what that one given angle is .. but it's that mystery angle subtracted from 180 give the angle BOA then you know that's an isosceles triangle again that the BOA is part of... so then just subtract BOA from 180 to find the two other angle of that triangle... they are the small so just divide your answer of 180-BOA /2 is the angle of each.. then since you know those to smaller angles subtract one from 90 to find the angle BAX
2) ( as we would read normally)
You're making this really tough on me.. I can just barely read the equations
I think it's 1+6x and 7x-3 . b/c they are the same length sides you can set those equal
1+6x = 7x -3
4+6x = 7x
4 = x
that worked out well :
for the tangent.. it's Tan(Ф)= Opp/ Adj
but I don't know which side they want to solve for.. I think you may have left off some of the instructions???? :/
ohh I think they really mean.. what's the length of the tangent lines .. that was confusing to me.. :/ just plug in 4 into x for either eq.
1+6(4) = 25
or
7(4)-3=25
tangent is 25
3)
x-2 = 2x-10
x+8 = 2x
8 = x
again they made it work out easy :)
Then plug 8 into either equation to find the length of the tangent lines
8-2=10
tangent is 10
4) = 2) ??? they are the same question maybe you meant to put something else?

An individual needs a daily supplement of at least 464 units of vitamin C and 252 of vitamin E and agrees to obtain this supplement by eating two foods, I and II. Each ounce of food I contains 32 units of vitamin C and 9 units of vitamin E, while each ounce of food II contains 16 units of vitamin C and also 18 units of vitamin E. The total supplement of these two foods must be at most 35 ounces. Unfortunately, food I contains 48 units of cholesterol per ounce and food II contains 25 units of cholesterol per ounce. Find the appropriate amounts of the two food supplements so that cholesterol is minimized. Find the minimum amount of cholesterol.

units of vit. C units of vit.E Cholesterol by ou
x₁ 32 9 48

$987.65 is invested at 0.4% annual interest for 5 years.
a. Simple Interest b. Compound Interest
Answers
Answer:
I. Simple interest = $19.753
II. Compound interest = $1007.6
Step-by-step explanation:
Given the following data;
Principal = $987.65
Interest rate, R = 0.4%
Time, T = 5 years
To find the simple interest;
S.I = PRT/100
S.I = (987.65*0.4*5)/100
S.I = 1975.3/100
S.I = $19.753
II. To find the compound interest;
[tex] A = P(1 + \frac{r}{100})^{t}[/tex]
Substituting into the formula, we have;
[tex] A = 987.65(1 + \frac{0.4}{100})^{5}[/tex]
[tex] A = 987.65(1 + 0.004)^{5} [/tex]
[tex] A = 987.65(1.004)^{5} [/tex]
[tex] A = 987.65(1.0202)[/tex]
A = $1007.6

Step-by-step explanation:
we are given a equation
we want to make n the independent variable
to do so
move -2n to right hand side and change its sign:
[tex] \displaystyle 3m = 12 + 2n[/tex]
divide both sides by 3:
[tex] \displaystyle m = \frac{12 + 2n}{3} [/tex]
further simplification is needed:
[tex] \displaystyle m = \frac{12 }{3} + \frac{2n}{3} [/tex]
[tex] \displaystyle m = \frac{2}{3} n + 4[/tex]
now m depends on n and n can be any value so we have rearranged n to independent variable

To test the durability of cell phone screens, phones are dropped from a height of 1 meter until they break. A random sample of 40 phones was selected from each of two manufacturers. The phones in the samples were dropped until the screens broke. The difference in the mean number of drops was recorded and used to construct the 90 percent confidence interval (0.46, 1.82) to estimate the population difference in means. Consider the sampling procedure taking place repeatedly. Each time samples are selected, the phones are dropped and the statistics are used to construct a 90 percent confidence interval for the difference in means. Which of the following statements is a correct interpretation of the intervals?
A. Approximately 90 percent of the intervals will extend from 0.46 to 1.82.
B. Approximately 90 percent of the intervals constructed will capture the difference in sample means.
C. Approximately 90 percent of the intervals constructed will capture the difference in population means.
D. Approximately 90 percent of the intervals constructed will capture at least one of the sample means.
E. Approximately 90 percent of the intervals constructed will capture at least one of the population means.
Answers
Answer:
C. Approximately 90 percent of the intervals constructed will capture the difference in population means.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
90% confidence interval for the difference in population means is of (0.46, 1.82). This means that we are 90% sure that the true difference between the population means is between these two values, and approximately 90% of intervals will capture this, which means that the correct answer is given by option C.
Answer:
C. Approximately 90 percent of the intervals constructed will capture the difference in population means.

There are exactly 2 students with 3 pets. There are exactly 3 students with 2 pets. There are exactly 2 students with more than 3 pets. There are exactly 3 students with more than 2 pets.

Answer:
A dot plot is similar to histogram wherein they show the frequency of data. In this kind of plot, instead of bars, dots are stacked on their corresponding bin. The bins here are the number of pets, while the dots are the students. So, the 2 dots above number 3 signifies that, there are two students with three pets. The answer is A.

Choose all answers that apply:
A: The Distribution has an Outlier
B: The Distribution has a peak at 22 degrees celsius
C: None of the Above
Answers
Answer:
B: The Distribution has a peak at 22 degrees celsius
Step-by-step explanation:
We are given a photo of a point plot, including with several descriptions and are asked to find which accurately describes the picture.
Let's take a look at our options,
A: The Distribution has an Outlier
This would be incorrect, an outlier is a point on any graph that doesn't really fit in well with all the other points, say there is a straight line with a bunch of dots surrounding it, then there is one dot that is far away from the rest, that is an outlier. Looking at the point plot, we see that all the dots fit in well together and no dots are really separated, therefore making this incorrect.
B: The Distribution has a peak at 22 degrees celsius
This would be correct, when referring to peak, the peak is supposed to represent the highest point or value a certain number/amount has. If we look at the point plot, we can see that there are the most dots at 22 than any other temperature. Therefore making it the peak, and making B correct.
C: None of the Above
This is obviously incorrect, B is a correct answer.
