If the wholesale price of a pair of shoes is $32.00, and the markup is 55%, find the selling price of the item.
Answer:
$49.6
Step-by-step explanation:
Given that :
Wholesale price, p = $32
Markup percentage = 55%
Selling price = wholesale price * ( 1 + Markup percentage)
Selling price = $32(1 + 0.55)
Selling price = $32(1.55)
Selling price = $49.6
A geometric sequence has an initial value of 2 and a common ratio of 3. Which formula would be more practical to use if you were looking find the value of the 19th number in the sequence?
Answer:
19th term = ar^18
19th term = 774,840,978
Step-by-step explanation:
First term, a = 2
Common ratio, r = 3
nth term of a geometric sequence = ar^(n-1)
19th term = ar^(19-1)
19th term = ar^18
= 2 × 3^18
= 2 × 387,420,489
= 774,840,978
19th term = 774,840,978

On the first day of class, Alana skimmed the first 17 pages from each of the books
assigned in her literature class. Each assigned book has an equal number of pages. Is
this sample of the assigned reading likely to be biased or unbiased?Why?
A . biased; convenience sample
B . unbiased; represents population
C .biased; voluntary sample
D .unbiased; random sample
Answer:
A. biased; convenience sample
Step-by-step explanation:
Alana is reading the first 17 pages, which are what is most conveniently available.
The sample of the assigned reading likely to be biased and convenience sample.
What is probability?probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.
Given:
Alana skimmed the first 17 pages from each of the books
assigned in her literature class. Each assigned book has an equal number of pages.
According to given question we have
A biased estimator is one that deviates from the true population value. A biased sample can still be useful if the nature of the bias and how much of a bias exists is known.
An unbiased estimator is when a value from a sample is the same as the actual value of a population parameter.
The sample is not chosen at random, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied. This undermines your ability to make generalizations from your sample to the population you are studying.
Therefore, the sample of the assigned reading likely to be biased and convenience sample.

ellen has a coupon for 1.55 off a loaf of bread. the regular price of the bread is 4.63. the loaf is cut into 14 slices. what is the price per slice if ellen uses her coupon?
Answer:
$0.22
Step-by-step explanation:
Ellen has a coupon of 1.55 off a loaf of bread
The regular price of the bread is 4.63, the loaf is cut into 14 slices
Therefore if she uses her coupon the price per slice can be calculated as follows
= 4.63-1.55
= 3.08
3.08/14
= 0.22
Hence the price is $0.22
Which expression is equivalent to the given expression? 6ab/(a^0b^2)^4
Answer:
B
Step-by-step explanation:
[tex]x^{0} = 1\\\\\frac{x^{m}}{x^{n}}= \frac{1}{x^(n-m)}}, n >m\\\\\\\frac{6ab}{(a^{0}b^{2})^{4}}=\frac{6ab}{(1*b^{2})^{4}}\\\\=\frac{6ab}{b^{2*4}}\\\\=\frac{6ab}{b^{8}}\\\\=\frac{6a}{b^{8-1}}\\\\=\frac{6a}{b^{7}}[/tex]
The equivalent expression of 6ab/(a^0b^2)^4 is 6a/b^7
How to determine the equivalent expression?The expression is given as:

Points of the diagonal: (-2, -2) and (2, 4)
d = [tex]\sqrt{(2-(-2))^2+(4-(-2))^2}[/tex]
d = [tex]\sqrt{(2+2)^2+(4+2)^2}[/tex]
d = [tex]\sqrt{(4)^2+(6)^2}[/tex]
