Answer:
0.07776, 0.3456,0.08704
Step-by-step explanation:
Given that a new surgical procedure is said to be successful 60% of the time
Let X be the no of successes
Then X has only two outcomes and each trial is independent of the other
Hence X is binomial with p = prob of success in a single trial = 0.60
n = Number of operations performed = 5
Prob that
a) all five operations are successful =
(b) exactly three are successful
=
(c) less than two are successful
Answer:
Step-by-step explanation:
Using the data presented in the problem, you are asked to
predict the probability that future customers will cancel their preorders. To find
the probability, you have to divide the number of people who cancelled their
preorders by the total number of people who preordered.
35 people / 140 people = .25 or 25% probability that the
future customers will cancel their preorders.
Answer:
12
Step-by-step explanation:
if R = 9
9-8=1
9 + 3 = 12
12*1=12
The height of the mountain estimated by two students is 2,467.98 meters.
<h3>
Height of the mountain </h3>
The height of the mountain is calculated as follows;
tanα = h/( a + b + x)
where;
- x is the distance between end of b and h
tan37 = h/(1850 + 740 + x)
tan37 = h/(2590 + x)
h = tan37(2590 + x)
h =1,951.82 + 0.7536x ---- (1)
tanβ = h/(b + x)
tan60 = h/(740 + x)
h = tan60(740 + x)
h = 1,281.68 + 1.732x ---- (2)
Solve (1) and (2) together
1,951.82 + 0.7536x = 1,281.68 + 1.732x
1,951.82 - 1,281.68 = 1.732x - 0.7536x
670.14 = 0.9784x
x = 684.93 m
h = 1,281.68 + 1.732x
h = 1,281.68 + 1.732(684.93)
h = 2,467.98 m
Thus, the height of the mountain estimated by two students is 2,467.98 meters.
