What is the slope of the straight line through points (-2,4) and (5,-1) ?

1 answer:

3 0

The slope can be calculated by subtracting the y values (the rises) and dividing the difference by the difference between the x values (the runs) to get rise over run. -1-4= -5 (differences in y's) & 5-(-2)= 7 (the differences in the x's). now divide the difference in the y' by the difference in the x's to get m= -5/7.

Answer:

The probability of seeing both = 0.32

Step-by-step explanation:

Step:-(i)

Given data the probability that you see a butterfly during a nature center tour is 80%

Let 'B' be the event of butterfly during a nature center tour

The probability that you see a butterfly during a nature center tour is 80%

P(B) = 80% = 0.80

Given data the probability that you see a turtle is 40%

Let 'T' be the event of turtle a nature center tour

P(T) = 40% = 0.40

Step:-(ii)

Independent events

If the occurrence of the event B is not effected by the occurrence or non-occurrence of the event 'A' , then the event 'B' is said to be independent of 'A'

If A and B are independent events then

P(A ∩B) =P(A) P(B)

now the given data the butterfly and turtle are independent events

probability of seeing both

P(B∩T) = P(B).P(T)

= 0.80 × 0.40

= 0.32
