Answer:
The answer to the question is;
Yes, it is very significant as the number of of observed vaccinated children is below the number of actually vaccinated children by 78.
Step-by-step explanation:
The result of the survey of more than 13,000 children indicate that only 89.4 % had actually been and the P-value indicate that the chance of having a sample proportion of 89.4 % vaccinated is 1.1 %.
P is low at 0.011 for which however the proportion of those vaccinated is between 0.889 and 0.899 using a 95% confidence interval, whereby the decrease from 90 % believed to 89.9 % is small, albeit it depends on the size of the population.
At 89.4 %, in a sample of 13,000, the number of children expected to have been vaccinated but were missed is equal to 90 - 89.4 = 0.6 % = 0.006
Therefore the children missed = 78 children which is significant.
Formula for Riemann Sum is:

interval is [1,3] so a = 1, b = 3
f(x) = 3x , sub into Riemann sum

Continue by simplifying using properties of summations.

Now you have an expression for the summation in terms of 'n'.
Next, take the limit as n-> infinity.
The limit of

goes to 0, therefore the limit of the summation is 12.
The area under the curve from [1,3] is equal to limit of summation which is 12.
Answer:
36 pi
Step-by-step explanation:
Aera of sphere is : 4 *pi *r^2
A=4 *pi*9=36pi=113
Answer:
open brackets we get
6x³ - 9x² + 6x + 10x² - 15x + 10
6x³ + x² -9x + 10
