Three-fourths of a research team worked in a lab while one-fourth of the team worked near a pond. Of the researchers who worked
Lisa [10]

Answer:

3.5%

Step-by-step explanation:

In this case, the final probability would be the product of the two probabilities that the plating shows us:

First probability would be:

We are told that three quarters of the equipment (3/4) in the laboratory and the other quarter (1/4) near the pond, we are interested in the latter, that is, the probability is 1/4 = 0.25

Second probability:

We are told that 14% collected insects, therefore it would be 0.14

The final product is the question they ask us:

0.25 * 0.14 = 0.035

Which means that the joint probability is 3.5%

Need some help please​
Kazeer [188]

Answer:

Sin(R)  = 15/17

Cos(R) = 8/17

Tan(R) = 15/8

Step-by-step explanation:

Sin = Opp./Hypo, Cos = Adj./Hypo. and Tan = Opp./Adj.

So

Sin(R) = Opp./Hypo = 60/68 = 15/17

Cos(R) = Adj./Hypo =32/68 = 8/17

Tan(R) = Opp./Adj. = 60/32 = 15/8
