Select the correct answer for each statement Will yield consecutive odd integers Will yield consecutive integers
Ivahew [28]

Complete question :

Select the correct answer for each statement.

1.) Will yield consecutive odd integers.

k+10, k+12, k+14

or

k+2, k+3, k+4

2.) Will yield consecutive integers.

k+1, k+2, k+3

or

k+6, k+8, k+10

Answer:

Consecutive odd integer : k+10, k+12, k+14

Consecutive integers : k+1, k+2, k+3

Step-by-step explanation:

Odd integers are numbers which aren't divisible by 2 ; such as : 1, 3, 5, 7, 9, 11,... The series continues in that manner. Consecutive odd integers have a common difference of 2, just as indicated in the instance given ; 1, 3, 5, 7, 9, 11,...

Therefore a series with a difference of 2 is more likely to be one representing consecutive odd integers.

2.) for concmsecutive integers :

Consecutive integers have a common difference of 1 between each successive integer ;

Hence, k+1, k+2, k+3 will most likely represent consecutive integers since the value of k is the same.

UkoKoshka [18]

Answer:

The probability that 8 mice are​ required is 0.2428.

Step-by-step explanation:

Given : A scientist inoculates​ mice, one at a​ time, with a disease germ until he finds 3 that have contracted the disease. If the probability of contracting the disease is two sevenths.

To find : What is the probability that 8 mice are​ required? The probability that that 8 mice are required is nothing ?

Solution :

Applying binomial distribution,

P(X=r)=^nC_r p^rq^{n-r}

Where, p is the probability of success p=\frac{2}{7}

q is the probability of failure q=1-p, q=1-\frac{2}{7}=\frac{5}{7}

n is total number of trials n=8

r=3

Substitute the values,

P(X=3)=^8C_3 (\frac{2}{7})^3 (\frac{5}{7})^{8-3}

P(X=3)=\frac{8!}{3!5!}\times \frac{8}{343}\times (\frac{5}{7})^{5}

P(X=3)=\frac{8\times 7\times 6}{3\times 2\times 1}\times \frac{8}{343}\times \frac{3125}{16807}

P(X=3)=0.2428

Therefore, the probability that 8 mice are​ required is 0.2428.
