I was taught how to do this using the SOH CAH TOA method.
Step 1: Circle your given angle.
Step 2: Label O, H, and A. The line across from your circled angle will be labeled O. The side across from the right angle is H. The last unmarked side is A.
Step 3: Cross off the useless side, in this case, that would be A because there is no corresponding information.
Step 4: Identify if it is sine, cosine, or tangent using SOH CAH TOA. In this case, you only have an O and H so we will use SOH.
Step 5: Set up the equation. The equation is [tex]\frac{sine(31)}{1} =\frac{x}{10}[/tex]. We will use sine of the given angle is equal to the side marked O over the side marked H.
Step 6: Solve for x until x is by itself, then enter into your calculator.
You will enter [tex]sine(31) * 10[/tex] into your calculator and round if necessary.

A cohort study of smoking and lung cancer was conducted in a small island population. There were a total of 1,000 people in the study, and the study was conducted over a ten year period. Four hundred were smokers and 600 were not. Of the smokers, fifty developed lung cancer. Of the non-smokers, 10 developed lung cancer. In order to measure the strength of association between smoking and lung cancer in this population, which measure of exposure-disease association would you use
Answers
Answer:
A measure of exposure-disease association one could use is the odds ratio (OR)
Step-by-step explanation:
An Odds ratio (OR) is a statistical measure quantifying the level of association between two events such as an exposure and an outcome
The odds ratio gives the probability of outcome where there is a given amount of exposure
We have the table;
[tex]\begin{array}{ccc}&Developed \ lung \ cancer& Did \ not \ develop \ lung \ cancer\\Smokers&50&350\\Non-smokers&10&590\end{array}[/tex]
The odds ratio = (The number of smokers with the lung-cancer)/(The number of non-smokers with lung-cancer) ÷ (The number of smokers smokers without long cancer).(The number of non-smokers without long cancer)
∴ OR = (50/10) ÷ (350/590) = 59/7 = 8.[tex]\overline{428571}[/tex] ≈ 8.4
Therefore, a smoker is approximately 8.4 times more likely to develop lung cancer than a non-smoker.

Step-by-step explanation:
4x + 2x = 180° because they are supplemental angles

divide both sides of the equation by 6:
x = 30°
6x=180
6x/6 = 18/6
x=30

A student believes that a certain number cube is unfair and is more likely to land with a six facing up. The student rolls the number cube 45 times and the cube lands with a six facing up 12 times. Assuming the conditions for inference have been met, what is the 99% confidence interval for the true proportion of times the number cube would land with a six facing up?
0.27 plus-or-minus 2.58 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot
0.73 plus-or-minus 2.33 StartRoot StartFraction 0.73 (1 minus 0.73) Over 45 EndFraction EndRoot
0.27 plus-or-minus 2.33 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot
0.73 plus-or-minus 2.58 StartRoot StartFraction 0.73 (1 minus 0.73) Over 45 EndFraction EndRoot
Answers
Answer: Option #1
Step-by-step explanation:
99 % confidence level - so it has to be 2.58 not 2.33 ( thats 98% confidence level )
then 12times facing u out of 45 times .... 12/45= .27
Option #1 : 0.27 +/- 2.58 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot
The 99% confidence interval for the true proportion of times the number cube would land with a six facing up is 0.27 plus-or-minus 2.58 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot.
What is Confidence Interval?This is an operation which is used to measure probability that a parameter will fall between a pair of values around the mean
99 % confidence level is closer to 2.58 and 12 times facing up out of 45 times which is 12/45= .27
Hence the reason why option A was chosen as the most appropriate choice.

Answers
Given:
A quadrilateral has vertices at (1,4), (7,3), (3, -5), and (8,4).
The quadrilateral is dilated by a scale factor of 3.5 with the origin as its center.
To find:
The coordinates of the vertices of the image of the quadrilateral.
Solution:
If a figure is dilated by a scale factor k with origin as it center, then
[tex](x,y)\to (kx,ky)[/tex]
It is given that the quadrilateral is dilated by a scale factor of 3.5 with the origin as its center. So, the rule of dilation is
[tex](x,y)\to (3.5x,3.5y)[/tex]
Using this rule, we get
[tex](1,4)\to (3.5(1),3.5(4))[/tex]
[tex](1,4)\to (3.5,14)[/tex]
Similarly,
[tex](7,3)\to (3.5(7),3.5(3))[/tex]
[tex](7,3)\to (24.5,10.5)[/tex]
[tex](3,-5)\to (3.5(3),3.5(-5))[/tex]
[tex](3,-5)\to (10.5,-17.5)[/tex]
And,
[tex](8,4)\to (3.5(8),3.5(4))[/tex]
[tex](8,4)\to (28,14)[/tex]
Therefore, the coordinates of the vertices of the image of the quadrilateral are (3.5,14), (24.5,10.5), (10.5,-17.5), (28,14).

Supposed B is the midpoint of line AC. Use the given information to find the missing measure. AB = 6Y -14, BC = 10-2Y 2Y, what is AC
Answers
Given:
B is the midpoint of line AC.
[tex]AB=6Y-14[/tex]
[tex]BC=10-2Y[/tex]
To find:
The length of AC.
Solution:
It is given that B is the midpoint of line AC. So,
[tex]AB=BC[/tex]
[tex]6Y-14=10-2Y[/tex]
[tex]6Y+2Y=10+14[/tex]
[tex]8Y=24[/tex]
Divide both sides by 8.
[tex]Y=\dfrac{24}{8}[/tex]
[tex]Y=3[/tex]
The value of Y is 3.
Now,
[tex]AC=AB+BC[/tex]
[tex]AC=6Y-14+10-2Y[/tex]
[tex]AC=4Y-4[/tex]
Putting [tex]Y=3[/tex], we get
[tex]AC=4(3)-4[/tex]
[tex]AC=12-4[/tex]
[tex]AC=8[/tex]
Therefore, the length of AC is 8 units.
