Answer:
$27.99
Step-by-step explanation:
100/7.25% sales tax = 1.54 x 13.7931034483 = 21.2413793104
We did the example to prove that when accounting for fixed tax the price will be higher once tax of same percentage amount applied.
This proves 1.75% more in interest is a far lower price ($6.56 less)
Where we compare the price set for 5.5 as asked in the question.
100/5.5% sales tax = 1.54 x 18.181818181 =27.9999999987
=$27.99
We do not round up or down repeating numbers.
Answer:
(a+b)(2x−ab+a−b)+x(a−b)+x²
Step-by-step explanation:
I can't make a good explanation, so here's a graph.
Also, this wouldn't be a proportional relationship because of exponents on the last term.
This is really a parabola.
Answer:
When selecting a sample for a survey, the way you choose your sample: <u>A) may lead to biased results</u>.
Step-by-step explanation:
The way you choose your sample matters a lot in order to help limit the bias in sampling data.
There are <em>four types</em> of <u>random</u> samples: simple, stratified, cluster, and systematic.
There are <em>two types </em>of <u>non-random</u> samples: voluntary response and convenience.
You always want to have a random sample in order to have accurate, non-biased results. Therefore, A) May lead to biased results is the best answer.
Answer:
55
Step-by-step explanation:
1st you would find the equation which would be (16 + 6.50x) = (10 + 7.50x) then you would find the answer which would be x = 6 then you would do 6.50 times 6 which would give u 39 add that to 16 which is 55 and do the same on the other side (7.50 times 6) which would give u 45 and then add the 10 which is 55 so the answer is 55.
75 because
9 = .12x
9/.12 = 75
