Answer 1

Answer

40.1

Area of a triangle using sine rule = 1/2 a b sinC

a and b are the two known sides, sinC is the angle opposite the unknown side

1/2 x 14 x 7 sin(125) = 40.1 to the nearest tenth

Answers

Answer:

275

Step-by-step explanation:

Answer:

Total Cost = $275

Step-by-step explanation:

25% = 0.25

Multiply $220 by 0.25 to get 25% of $220.

0.25 × $220 = $55

Now add $220 and $55 to get the total cost.

$220 + $55 = $275

provided on your answer document.

Answers

I’m certain 162, 6•12= 72, and 6•15= 90

Answer: 162

Step-by-step explanation:

6(12+15) Following the order of operations, (P.E.M.D.A.S), you should do parentheses first. So you add 12 and 15 to get 27. Were left with 6(27). So we multiply 6 and 27. The final answer is 162.

Bill launched a model rocket, and estimated its height h, in feet, after 1 seconds. His results are shown in the table.
Time to 1 2 3 4
Height, h 0 110 190 240 255
Bill's data can be modeled by the function h(t) = -16t2 + 128t.
Which value is the best prediction for the height of the rocket after 5.5 seconds?
A. 150 ft
B. 180 ft
C. 220 ft
D. 250 ft
E 260 ft

Answers

Answer:

22ft

Step-by-step explanation:

Given the height of Bills modeled by the function h(t) = -16t^2 + 128t.

To get his height after 5.5secs, we will replace t with 5.5 a shown;

h(t) = -16t^2 + 128t.

h(5.5) = -16(5.5)^2 + 128(5.5)

h(5.5) = =-484+704

h(5.5) = 220ft

Hence his height after 5.5secs is 22ft

Answers

Answer:

4/8.

Step-by-step explanation:

4/8 is the correct answer for this question. This is why. If you take 8 and divide it in half, your answer will be 4. Also because fractions are division so the fraction 8/2 equals 4. This means the 1/2 mark is equal to 4.

The water works commission needs to know the mean household usage of water by the residents of a small town in gallons per day. They would like the estimate to have a maximum error of 0.14 gallons. A previous study found that for an average family the variance is 1.69 gallons and the mean is 15.9 gallons per day. If they are using a 85% level of confidence, how large of a sample is required to estimate the mean usage of water? Round your answer up to the next integer.

Answers

Answer:

A sample of 179 is needed.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.85}{2} = 0.075[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.075 = 0.925[/tex], so Z = 1.44.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

A previous study found that for an average family the variance is 1.69 gallon?

This means that [tex]\sigma = \sqrt{1.69} = 1.3[/tex]

If they are using a 85% level of confidence, how large of a sample is required to estimate the mean usage of water?

A sample of n is needed, and n is found for M = 0.14. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.14 = 1.44\frac{1.3}{\sqrt{n}}[/tex]

[tex]0.14\sqrt{n} = 1.44*1.3[/tex]

[tex]\sqrt{n} = \frac{1.44*1.3}{0.14}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.44*1.3}{0.14})^2[/tex]

[tex]n = 178.8[/tex]

Rounding up

A sample of 179 is needed.

The Brisbane Manufacturing Company produces a single model of a CD player. Each player is sold for $182 with a resulting contribution margin of $71. Brisbane's management is considering a change in its quality control system. Currently, Brisbane spends $42,000 a year to inspect the CD players. An average of 1,900 units turn out to be defective: 1,520 of them are detected in the inspection process and are repaired for $75. If a defective CD player is not identified in the inspection process, the customer who receives it is given a full refund of the purchase price. The proposed quality control system involves the purchase of an x-ray machine for $210,000. The machine would last for five years and would have salvage value at that time of $18,000. Brisbane would also spend $470,000 immediately to train workers to better detect and repair defective units. Annual inspection costs would increase by $25,000. Brisbane expects this new control system to reduce the number of defective units to 400 per year. 350 of these defective units would be detected and repaired at a cost of only $41 per unit. Customers who still receive defective players will be given a refund equal to 120% of the purchase price.Required:a. What is the Year 3 cash flow if Brisbane keeps using its current system?b.
