30b³ + 20b² + 15b + 10 = ...(:5)
6b³ + 4b² + 3b + 2 =
6b³ + 3b + 4b² + 2 =
3b(2b²+1) + 2(2b²+1) =
(2b²+1)*(3b+2)
Answer:
Step-by-step explanation:
You can break it down to:
5 * 2 * 
10 * = 10/6 Reduce to 5/3
So the problem can be simplified to:
Answer:
False
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
95% confidence interval for the mean number of oranges eaten per week per person is 0.8 to 2.6.
This means that we are 95% sure that the true population means for the number of oranges eaten per week per person is 0.8 to 2.6, not that 95% of all people eat between 0.8 and 2.6 oranges per week. So the answer is False.
Solution:
Rewriting input as fractions if necessary:
1/10, 3/4, 1/2
For the denominators (10, 4, 2) the least common multiple (LCM) is 20.
Therefore, the least common denominator (LCD) is 20.
The values of x and y are 5 and 2 respectively
