Question #1:

Put the markup as a decimal.

80% = 0.8

Multiply.

0.8 * 300 = 240

Add.

300 + 240 = $540

The price of the sofa after markup is $540

Question #2:

Divide.

8 / 90 = 0.0888888

Multiply.

0.0888888 * 100% = 8.88888%

Round.

8.89%

8.89% is the percent of 90 is 8.

Question #3:

Turn percentage into a decimal.

80% = 0.8

Multiply

300 * 80 = 240

80% of 300 is 240

Question #4:

Put the markup as a decimal.

8.01% = 0.0801

Multiply.

2,500 * 0.0801 = $200.25 (markup)

Add.

2,500 + 200.25 = $2,700.25

The price after markup is $2,700.25

how many liters of 40% oil dressing should be mixed with 4 liters of a dressing that is 25% oil to get a dressing that is 30% oi
Ronch [10]
Volume of first oil = A, volume of second oil = B, volume of mixture = M
A = ?, B = 4l, M = A + B

40%A + 25%B = 30%M
40%A + 25%4l = 30%(A+4l)
<span>40%A + 25%4l = 30%A + 30%4l
40A + 100l = 30A + 120l
40A - 30 A = 120l - 100l
10A = 20l
A = 2l
</span>
Answer: 2 litres of 40% oil dressing.

Also note: That's an approximation, because the volumes are not strictly additive. For example: mixing 50ml pure ethanol with 50ml water will give you about 95ml of mixture. To get an accurate answer, you'd have to measure the volume of the final mixture and then divide your total oil content by that<span>.</span>

Because of high production-changeover time and costs, a director of manufacturing must convince management that a proposed manuf
7nadin3 [17]

Answer:

See explanation below

Step-by-step explanation:

Here, a director of manufacturing must convince management that a proposed manufacturing method reduces costs before the new method can be implemented. The current production method operates with a mean cost of $220 per hour.

a) The alternative and null hypotheses would be:

H0: μ ≥ 220

Ha: μ < 220

b) Comment on the conclusion when H0 cannot be rejected:

When we fail to reject the null hypothesis H0, there is not enough evidence to conclude that the mean cost can be reduced from $220. Therefore the manager's proposed method cannot be implemented.

c) Comment on the conclusion when H0 can be rejected:

When the null hypothesis, H0 is rejected, there is enough evidence to conclude that the mean cost can be reduced from from $220. Therefore the manager's proposed method can be implemented.
