Can someone help me please

Olin [163]

Since $50 is the fixed rate that would be your y intercept. Since $25 is charged per hour, this value changes and is the slope. Therefore y=25x+50

I am just confused can someone help please...

The answer is B

sin=Opposite/Hypotenuse

sin=28/100

Divide numerator and denominator by 4

sin=7/25

Cosine=adjacent/hypotenuse

cos=96/100

Divide numerator and denominator by 4

cos=24/25

Tangent=opposite/adjacent

tan=28/96

Divide numerator and denominator by 4

tan=7/24

For two events and , the probability that occurs is 0.8, the probability that occurs is 0.4, and the probability that both occur

sergey [27]

Answer:

P(B|A)=0.25 , P(A|B) =0.5

Step-by-step explanation:

The question provides the following data:

P(A)= 0.8

P(B)= 0.4

P(A∩B) = 0.2

Since the question does not mention which of the conditional probabilities need to be found out, I will show the working to calculate both of them.

To calculate the probability that event B will occur given that A has already occurred (P(B|A) is read as the probability of event B given A) can be calculated as:

P(B|A) = P(A∩B)/P(A)

= (0.2) / (0.8)

P(B|A)=0.25

To calculate the probability that event A will occur given that B has already occurred (P(A|B) is read as the probability of event A given B) can be calculated as:

P(A|B) = P(A∩B)/P(B)

= (0.2)/(0.4)

P(A|B) =0.5
