<span>Rewriting input as fractions if necessary:
3/2, 3/8, 5/6, 3/1

For (2, 8, 6, 1) the least common multiple (LCM) is 24.

Therefore, the least common denominator (LCD) is 24.

Rewriting as equivalent fractions with the LCD:
36/24, 9/24, 20/24, 72/24

How to find the missing side of a triangle while only given angles and one side?
OLga [1]
Hi there!

Since you haven't given any numbers, I'll explain what you can do to figure this problem out. First, determine what side you have in relation to the angle (is it adjacent to the angle, it is opposite the angle, is it the hypotenuse?). Then, determine which trigonometry function to use (Sine = opposite/hypotenuse, Cosine = adjacent/hypotenuse, Tangent = opposite/adjacent). Check out the image below if you're confused. Anyway, you can use trigonometry to find the missing side of a triangle when only given angles and a side. All you have to do is plug in the numbers given and solve. (In the image, the O with a line through it represents the angle measurement that will be plugged in there.)

Hope this helps!! :)
If you're still confused or would like help solving a trigonometry problem, feel free to send me a message!

puteri [66]

Answer:

1. 4(.8)-3.5= 3.2-3.5= -0.3

2. 3(3)--5(5)-9(-1)= 9 - 25 + 9 = 18 - 25= -7

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia and older subjects before treatment 14
RideAnS [48]

Answer:

99% confidence interval estimate of the mean weight time for a population with drug treatments

(79.11 , 112.69)

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given data mean of the Population = 104 minutes

Given sample size 'n' =14

Mean of the sample(x⁻)  = 95.9 minutes

Given Standard deviation  = 24.4 minutes

<u><em>Step(ii)</em></u>:-

99% confidence interval estimate of the mean weight time for a population is determined by

(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} +Z_{0.01} \frac{S.D}{\sqrt{n} })

(95.9 - 2.576\frac{24.4}{\sqrt{14} } , 95.9+2.576\frac{24.4}{\sqrt{14} })

On calculation , we get

(95.9 -16.79 , 95.9 +16.79)

(79.11 , 112.69)

<u><em>Conclusion:</em></u>-

99% confidence interval estimate of the mean weight time for a population with drug treatments

(79.11 , 112.69)
