Answer: 1.48

Step-by-step explanation:

From binomial distribution, the formula to find the standard deviation is given by :-

\sigma=\sqrt{np(1-p)}, where n is the sample size and p is the proportion of success.

Given : The percent of chance that a candle is defective. If the company selected 50 candles off the line : 4.6%

i.e. The proportion of success : p=0.046

Sample size : n=50

Then, Standard deviation = \sigma=\sqrt{50(0.046)(1-0.046)}

\sigma=1.48128322748\approx1.48

Hence, the standard deviation of the number of defective candles in the group=1.48

Answer:

Animal books make up (3/20) of all books

Step-by-step explanation:

Let X be the total number of books, made up of nonfiction, animal, and all others.

(3/5)X are nonfiction books.

Of the nonfiction books, 1/4 are animal books:  (3/5)*(1/4)X = (3/20)X are animal books

[This means that Nonfiction, less animal books is:  (3/5)X - (3/20)X]

Animal books make up (3/20) of all books.

How much did she spend on food during the three months
Dima020 [189]

Answer:

$$563.20 or ≈$563.00

Step-by-step explanation

The question states that Mrs. Hadley spent $126.97 on one month, $237.81 on the next, and $198.42 on the last. To get the total, we can add these values together.

126.97+237.81+198.42=563.20

An estimation would be:

127+238+198=563

We can use this estimation to determine that the total value is reasonable.
