The sum of two consecutive even integers divided by four is 189.5

1 answer:

6 0

The sum of two consecutive even integers is a+(a+2) and divided by four is
(a+(a+2))/4 = 189.5
(2a+2)/4 = 189.5
2a+2 = 189.5 * 4
2a+2 = 758
2a = 758 - 2
2a = 756
a = 756/2 = 378
first number is a = 378
second number is a+2 = 378+2 = 380

quester [9]

Answer:

73.4

Step-by-step explanation:

-Given that 75,511 out of 822,959 residents enrolled in the college, the probability of success is calculated as:

$P_{enrollment}=\frac{Enrollment}{Total \ Residents}\\\\=\frac{75511}{822959}\\\\=0.09176\\\\p=0.09176$

#We know that this is a binomial distribution with p=0.09176 and n=800, Expected value is calculated as:

$E(X)=np, n=800, p=0.09176\\\\=0.09176\times 800\\\\=73.4$

Hence the expected value E(X)=73.4

Answer: second step.

Step-by-step explanation:

you then have to distribute the answer not subtract 9 1/4 from 1.5

you have to do the parenthesis next
