Answer:
The probability of seeing both = 0.32
Step-by-step explanation:
<u>Step:-(i)</u>
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
<u>Step:-(ii)</u>
<u>Independent events </u>
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
The system of equations is:
2x+1.5y=20
x+y=12
When you solve it you get:
x=4 hamburger bun packages
y=8 hot dog bun packages
Answer:
-0.72 (A)
Step-by-step explanation:
Slope = (y2 - y1) / (x2 - x1)
slope = (-7-10) / (5 - (-3)
slope is supposed to be -17/8
I am guessing she made her mistake by adding a negative sign...the student did : (-7 - (-10) / (5 - (-3) = (-7 + 10) / (5 + 3) = 3/8
