Answer:
probability = 0.008
probability = 0.0256
Explanation:
we know here probability of defective is 0.2
so probability of not defective is 1 - 0.2 = 0.8
as we know 3 item is arrive off process line in succession
so The probability that an item is defective is
as P(defective) = 0.20
as all item are independent so
probability that all three items are defective is
probability = 0.20 × 0.20 × 0.20 = 0.008
and
probability that exactly 3 of next 4 are defective
so number of way that can choose 3 out of 4 is
= 
= 4
so as all are independent probability is
probability = ( the number of way to choose 3 out of 4 ) × ( 3 item defective ) × ( 1 item not defective )
probability =
× 0.2³ × ( 1- 0.2)
probability = 4 × 0.008 × 0.8
probability = 0.0256
Answer:
the contribution margin per unit is $15 per unit
Explanation:
The computation of the contribution margin per unit is shown below:
Contribution margin per unit is
= Selling price per unit - variable cost per unit
= ($540,000 ÷ 9,000 units) - ($405,000 ÷ 9,000 units)
= $60 - $45
= $15 per unit
Hence, the contribution margin per unit is $15 per unit
Answer:
a trade surplus and positive net exports.
Explanation:
If a country sells more goods and services to foreign countries than it buys from them, it means the country's export is greater than its import. If export is greater than import, net exports (export- import ( would be postive.
Also, there would be a trade surplus.
A trade surplus is when the value of export is greater than imports.

Answer: C. are, predict
Explanation:
Improving stock prices and increasing factory production are why economists predict continuing economic improvement in the next quarter.
When there is an increase in the prices of stock and factory production, this can bring about an improvement in the economy as it will lead to economic growth as there will be increase in demand which ultimately leads to employment opportunities and also rise in the standard of living of the people.
