Answer: 0.85</h3>
Explanation:
If we start off with $100 and decrease by 15%, then we are decreasing by $15 since 15% of 100 = 0.15*100 = 15
We start with $100 and drop to 100-15 = 85. Dividing this over the original 100 gets us 85/100 = 0.85
Put another way, 100% - 15% = 1 - 0.15 = 0.85
The decimal multiplier for "decrease by 15%" is 0.85; this sort of thing is useful if you wish to apply multiple discounts to a product.
Side note: the 0.85 can be thought of as 85%, so the product's new value is 85% of its original value
Answer: A
Step-by-step explanation: when Constructing a confidence interval, it is important to take note of the margin of error which is given by the formulae below
Margin of error = critical value × σ/√n.
Where n is the sample size.
As we can see that the critical value is a constant and the population standard deviation.
Hence there is an inverse relationship between margin of error and sample size, which implies that a large sample size produces a small margin of error.
If the margin of error is small, it means the sample size will increase the like hood that the sample is a good representation of the population.
Answer:
u=25.6
Step-by-step explanation:
6.4=u/4
by cross multiplication
6.4×4=u
25.6=u
