Answer:
D] f(n) = f(n − 1) + (−7)
Step-by-step explanation:
since you already know is an arithmetic series, you have to find the common difference.
87 - 94 = -7
80 - 87 = -7
73 - 80 = -7
the formula for the nth term is f(n) = f(n-1) + d
where f(n-1) is the previous term and d is the common difference, so if youu substitute you get:
f(n) = f(n-1) + d
f(n) = f(n-1) + (-7)
He drove 193 mile you subtract 33 from 113 which is 80 then add 80 and 113 together and you get 193
Answer:
7.33333 hours
Step-by-step explanation:
Theo's speed = 55mph
Distance = speed * time
Distance covered after 2 hours
Distance = 55 * 2 = 110 miles (distance already covered by Theo when Dennis left
Dennis speed = 70mph
Let time taken to catch up = x
70x = 110 + 55x
70x - 55x = 110
15x = 110
x = 110 / 15
x = 7.33333 hours
Answer:
0.9590
Step-by-step explanation:
Given that Grafting, the uniting of the stem of one plant with the stem or root of another, is widely used commercially to grow the stem of one variety that produces fine fruit on the root system of another variety. Suppose grafts are done one at a time. Each graft is successful with probability 0.55, independently of each other.
We have X no of failures also would be binomial with p = 0.45 since each is independent of other.
Required probability
= P(x>0 in next four trials/x=0 in I seven trials)
= P(x>0 in next four trials)*P(x=0 in I seven trials)/P(x=0 in I seven trials)
= 1-P(x=0) in 4 trials
=
