The results of inspection of DNA samples taken over the past 10 days are given below. Sample size is 100.

ASHA 777 [7]

Answer:

The average defective rate = .057

Step-by-step explanation:

Given -

Sample size n = 100

Day - 1 2 3 4 5 6 7 8 9 10

Defectives - 7 6 6 9 5 6 0 8 9 1

The average defective rate is the no of defective in each day for past ten days

The average defective rate = $\frac{\sum no\; of \; effective \; in\; each\; day}{no\; of \; day \times n}$

= $\frac{7 + 6 + 6 + 9 + 5 + 6 + 0 + 8 + 9 + 1}{10\times 100}$

= $\frac{57}{1000}$

= .057

The sum of two numbers is 72. one number is 4 less than the other number. what are the two numbers?

-Dominant- [34]

Let 1st number be = x
Thus second number = x - 4

Now

(x) + (x - 4) = 72
2x - 4 = 72
2x = 76
x = 38

1st number is 38 thus 2nd number is (38 - 4) = 34

Kobotan [32]

61122122061 miles

We can use an equation to find how much miles she would drive in one hour, then multiply by 111111 hours:

183183183/333 = 550099.65

550099.65 * 111111 = 61122122061 miles
