Answer:
Step-by-step explanation:
Let the four consecutive integers be
x ,x+1,x+2,x+3
According to the given statement the sum of 2nd and 4th is 48 so,
x+1+x+3=48
2x+4=48
2x=44
x=22
So the four consecutive integers are
x=22,
x+1=23,
x+2=24,
x+3=25
27.2 is 68 percent of 40
to find this answer I divided 27.2 by 68 to find out how much 1 percent was; 1%=0.4then i just multiplied 0.4 by 100 to find out how much 100% was, and my answer was 40
hope this helps
Answer:
0.7633
Step-by-step explanation:
Proportion of the population that is contaminated = P = (4/17) = 0.235
We now need to find the probability that not more than 1 of the 4 bottles tested is contaminated. This is a binomial distribution problem.
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = number of bottles to be tested = 4
x = Number of successes required = 0, 1
p = probability of success = probability that a bottle is contaminated = 0.235
q = probability of failure = probability that a bottle is NOT contaminated = 1 - 0.235 = 0.765
P(X ≤ 1) = P(X=0) + P(X=1) = 0.34248830063 + 0.4208352975 = 0.7633235981 = 0.7633 to 4 d.p
