aev [14]

Answer:

True

Step-by-step explanation:

Formula

Tan(x) = opposite / adjacent

Givens

x = 42

adjacent = 14

opposite = ?

Solution

Tan(42) = opp/14 Find tan(42)

Tan(42) = 0.900404

0.900404 = opp/ 14 Multiply both sides by 14

14 * 0.900404 = opp/14 * 14 Simplify the left

12.6 rounded = opp

a = 12.6

A cohort study was conducted to study the association of coffee drinking and anxiety in a population-based sample of adults. Amo

azamat

Answer: Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.

Step-by-step explanation:

Since we have given that

Number of coffee drinkers = 10000

Number of whom developed anxiety = 500

Number of non coffee drinkers = 20000

Number of whom developed anxiety = 200

So, probability of getting anxiety from coffee drinkers = $\dfrac{500}{10000}=0.05$

Probability of getting anxiety from non coffee drinkers = $\dfrac{200}{20000}=0.01$

so, Relative risk of anxiety associated with coffee use is given by

$\dfrac{0.05}{0.01}=5$

Hence, Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
