Answer:

Explanation:

Experiments were performed for 240 people, 60 people test positive.

Step 1: we calculate the sample proportion; p= 60/240= 0.25.

Step 2: calculate the standard error for the sample, which is the square root of sample proportion,p = p(1-p)/n, n=100

0.25(1-0.25)/100

= 0.04.

Step 3: calculate the test statistics; assuming the hypothesis test percentage is 25%

Then, we say 0.25-1=0.75

-0.75/0.04

= -1.875.

In particular, the sample results are -1.875 standard error.

Probability of Z is less than -1.875.

Look up it value in the Z table

In most high-tech industries, the fixed costs of developing a product are very _____, and the costs of producing one extra unit
topjm [15]

Answer:

Fixed costs are high, variable costs are low

Explanation:

The reason is that the fixed costs are high because these fixed costs are uncontrollable and their might not be an alternative which means we have to move with higher fixed costs. And this is because most of tasks in manufacturing are handled by the machines not humans. So the cost of maintenance, depreciation, etc are fixed costs which are uncontrollable.

Furthermore, the company has very small variable costs because the company enjoys economies of scales, fast paced manufacturing machines, etc. And this is controllable by investments in another more robust machinery.

Which of the following options is a better purchase for a bicycle?
Bess [88]

Answer:

Option 3: $12 down with equal payments of $5 for 12 months

Explanation:

In option 1 :

The cost is $ 88,

In option 2 :

Down payment = $ 5,

Weekly payment = $ 8,

Number of weeks = 10,

So, the total cost = 5 + 8 × 10 = 5 + 80 = $ 85,

In option 3 :

Down payment = $ 12,

Monthly payment = $ 5,

Number of months = 12,

So, the total cost = 12 + 5 × 12 = 12 + 60 = $ 72,

In option 4 :

Down payment = $ 20,

Monthly payment = $ 20,

Number of months = 12,

So, the total cost = 12 + 20 × 12 = 12 + 240= $ 252

∵ 72 < 85 < 88 < 252

Hence, option 3 is better.
