All angles in a triangle add to 180 so

B = 180 - 90 - A
B = 90 - 20.8
B = 69.2

Can find b with tangent of A
tangent is opposite over adjacent.
opposite to A = 20.8 is 11.2 and adjacent is b

tan(20.8) = 11.2 / b
b = 11.2 / tan (20.8)
b = 29.5

c can be found with sine of A

sin(20.8) = 11.2 / c
c = 11.2 / sin(20.8)
c = 31.5

B = 69.2°,  b = 29.5, c = 31.5

What is the probability of getting an even number on the roll of a six-sided die? 1/6 1/3 1/2
givi [52]

Answer: 1/2

Step-by-step explanation:

The sample space when a six sided die is thrown once is :

{ 1,2,3,3,5,6}

The even numbers are :

{2,4,6}

Therefore :

P(even) = n(even) / total number

That is

P(even) = 3/6

P(even) = 1/2

At a competition with 8 runners, 2 medals are awarded for first and second
Dafna1 [17]

Answer: Option 'A' is correct.

Step-by-step explanation :

Since we have given that

Number of medals = 2

Number of runners = 8

We need to find the number of ways to award the medals.

We would use "fundamental theorem of counting" to find the number of ways.

So, number of ways is given by

8 × 7 = 56

Hence, option 'A' is correct.

A marketing firm tracks data on grocery store visits. In one study, it finds that the probability that a shopper buys bread duri
timurjin [86]

Answer:

Option B.

Step-by-step explanation:

Two events are said to be independent of each other, if the probability of one event ocurrin in not way affects the probability of the other event occurring.

The interception of two independent events P(A ∩ B) = P(A) × P(B), where:

P(A) = 0.70

P(B) = 0.20

P(A ∩ B) = P(A) × P(B) = 0.70x0.20 = 0.14

The two events are independent if the probability of buying Bread AND cheese equals: 0.14, which is Option B.
