Probability of the next six babies being a girl = (0.4810)^6 = 0.0124
Therefore probability of at least one boy in next six births = 1 - 0.0124
= 0.9876 Answer
Answer:
13.5
Step-by-step explanation:
The first one is the last answer because you subtract 18 and when you divide you change the inequality symbol
the second one is the last answer for the same reason
the 3rd one is x<-1.25
the 4th one is x<8/15
(d): y = mx+n
m = -2/3 ⇒ y = (-2/3)x +n
A(-4, 6) ∈ d ⇒ 6 = (-2/3)·(-4) +n ⇒ 6 = 8/3 +n ⇒
⇒ n = 6 - 8/3 ⇒ n = 10/3
Now, we have:
y = (-2/3)x +10/3
I would say your friends assumption is wrong. Why?
Because, if you payed $2.40 for 3/4 pounds of grapes, your friend should pay more for an entire pound, not less.
