Explain how to divide when the divisor is a decimal.
2 answers:
Answer:
Move the decimal point of the divisor to the right until it becomes a whole number. Move the decimal point od the dividend the same number of places, then do the division (long division).
When dividing by a decimal divisor, we use the following procedure:
1)Multiply the divisor by a power of 10 to make it a whole number.
2)Multiply the dividend by the same power of 10. 3(Place the decimal point in the quotient.
4)Divide the dividend by the whole-number divisor to find the quotient.
Step-by-step explanation:
see picture for example..

The total cost without the discount is given by:
$
Then, to find the discounted amount, we make the following rule of three:
10 $ ------------------> 100%
x ----------------------> 20%
From here, we clear the value of x.
We have then:

Answer:
The test is not significant at 5% level of significance, hence we conclude that there's no variation among the discussion sections.
Step-by-step explanation:
Assumptions:
1. The sampling from the different discussion sections was independent and random.
2. The populations are normal with means and constant variance
There's no variation among the discussion sections
There's variation among the discussion sections
Df Sum Sq Mean sq F value Pr(>F)
Section 7 525.01 75 1.87 0.99986
Residuals 189 7584.11 40.13
Test Statistic =
Since our p-value is greater than our level of significance (0.05), we do not reject the null hypothesis and conclude that there's no significant variation among the eight discussion sections.
