The mark up on an item is $3.75. If the mark up is 35%, what was the original price? Round
your answer to the nearest hundredth. (Show all work)
Answers
Answer:
$10.71
Step-by-step explanation:
[tex]\frac{3.75}{y} =\frac{35}{100}[/tex]
y × 35 = 3.75 × 100
35y = 375
35y ÷ 35 = 375 ÷ 35
[tex]y=10\frac{5}{7}[/tex]
y = 10.7142857143
10.7142857143 round to 10.71
First USA, a major credit card company, is planning a new offer for their current cardholders. The offer will give double airline miles on purchases for the next 6 months if the cardholder goes online and registers for the offer. To test the effectiveness of the campaign, First USA recently sent out offers to a random sample of 50,000 cardholders. Of those, 1184 registered. Give a 95% confidence interval for the true proportion of those cardholders who will register for the offer.
Answers
Answer:
The answer is "[tex]0.02235 \ and \ 0.02501[/tex]".
Step-by-step explanation:
Given:
[tex]x= 1184\\\\n = 50000\\\\c = 95\% = 0.95[/tex]
The sample proportion is computed by subtracting that sample size by both the successes:
[tex]\hat{p}=\frac{x}{n} =\frac{1184}{50000}= 0.02368[/tex]
Determine [tex]z_{\frac{\alpha}{2}} = Z_{0.025}[/tex] using table Z in Table Z for trust level [tex]1 -\alpha = 0.95[/tex]
add using appendix F ((0.025) inside the table, therefore the z-score is the found z-score with negative sign):
So, the boundaries of the confidence interval:
[tex]\to \hat{p}-z_{\frac{\alpha}{2}} \cdot \sqrt{\frac{\hat{p} (1-\hat{p})}{n}} = 0.02368 - 1.96 \cdot \sqrt{\frac{0.02368(1-0.02368)}{50000}}\approx 0.02235 \\\\\to \hat{p}-z_{\frac{\alpha}{2}} \cdot \sqrt{\frac{\hat{p} (1-\hat{p})}{n}} = 0.02368 + 1.96 \cdot \sqrt{\frac{0.02368(1-0.02368)}{50000}}\approx 0.02501\\\\[/tex]

a 56-inch board is to be cut into three pieces so that the second piece is three times as long as the first piece and the third piece is four times as long as the first piece if x represents the length of the first piece find the length of all three pieces
Answers
Step-by-step explanation:
length of 1st piece = x inch
length of 2nd piece = 3x inch
length of 3rd piece = 4x inch
x + 3x + 4x = 56
8x = 56
x = 7
Thus,
length of 1st piece = 7 inch
length of 2nd piece = 3 × 7 = 21 inch
length of 3rd piece = 4 × 7 = 28 inch

Solve the following equation for x: 6(4x + 5) = 3(x + 8) + 3. Round to the nearest hundredth.
Answers
Answer:
x ≈ -0.14
Step-by-step explanation:
6(4x + 5) = 3(x + 8) + 3
24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
21x + 30 = 27
21x = -3
x = [tex]\frac{-3}{21}[/tex]
x = [tex]-\frac{1}{7}[/tex]

Solve this system of equations using the substitution method y=5x+4 x+12=y
Answers
Answer:
(2,14)
Step-by-step explanation:
Since y=5x+4, you can plug that into the other y in the other equation which would give you x+12=5x+4
Now subtract 12 from both sides
x=5x-8
Subtract 5x from both sides
-4x=-8
Now you divide them both by -4 which gives you x=2
Now plug x in to any of the equations
y=5(2)+4
y=10+4
y=14
Your final answer is (2,14)
