I find it easiest to subtract and add the percentages to make a multiplier, then use that.
After the man's discount, he pays (100% - 12%) = 88% of the list price. After tax, he pays (100% + 3%) = 103% of the discounted price.
The amount he actually pays is $255×0.88×1.03 = $231.13.
The best choice is ...
(B) $231.13
We are given statement 3.59 > 3.5__1 >3.572.
We have a blank space in between 5 and 1 in the middle number given.
Given statement ccan be read as :
3.59 is greater than 3.5__1 is greater than 3.572.
So, we need to check a number that is less than 3.59 but less than 3.572.
The hundredth place of 3.59 number is 9 and
hundredth place of 3.572 number is 7.
So, we need to find a number between 7 and 9.
8 is the number in between 7 and 9.
So, the known digit can be replaced by 8 to make the statement true.
And final statement is 3.59 > 3.581 >3.572.
Answer:
Step-by-step explanation:
In the two independent samples application, it involves the test of hypothesis that is the difference in population means, μ1 - μ2. The null hypothesis is always that there is no difference between groups with respect to means.
Null hypothesis: ∪₁ = ∪₂. where ∪₁ represent the mean of sample 1 and ∪₂ represent the mean of sample 2.
A researcher can hypothesize that the first mean is larger than the second (H1: μ1 > μ2 ), that the first mean is smaller than the second (H1: μ1 < μ2 ), or that the means are different (H1: μ1 ≠ μ2 ). These ae the alternative hypothesis.
Thus for the z test:
if n₁ > 30 and n₂ > 30
z = X₁ - X₂ / {Sp[√(1/n₁ + 1/n₂)]}
where Sp is √{ [(n₁-1)s₁² + (n₂-1)s₂²] / (n₁+n₂-2)}
The answer is 12x^3-4×^2-4
Answer:
$.75
Step-by-step explanation:
9 ÷ 12 = 0.75
.75 × 12 = 9
