14,730,000 rounded to the nearest 10 million would be 10,000,000.
17,640,000 rounded to the nearest 10 million would be 20,000,000.
10,000,000+20,000,000=30,000,000
Answer:
x = -2/3; x = 5/2.
Step-by-step explanation:
6x 2 - 11x - 10 = 0
Use the 'ac' method:
6 * -10 = -60. We need 2 numbers whose product is -60 and whose sum is -11.
That would be -15 and +4. So we write:
6x^2 - 15x + 4x - 10 = 0 Factor by grouping:
3x(2x - 5) + 2(2x - 5) = 0
(3x + 2)(2x - 5) = 0
x = -2/3; x = 5/2.

Answer: 1.48
Step-by-step explanation:
From binomial distribution, the formula to find the standard deviation is given by :-
, 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 =
Hence, the standard deviation of the number of defective candles in the group=1.48
