You deposit $2200 Into three separate bank accounts for each pay 3% annual interest. How much interest does each account earn af
Hatshy [7]

The formula to find the amount is

A=P(1+r)^n

Here A = amount

P is the principal

r is the rate

n is the number of years

Then to find the interest we subtract principal from amount.

Interest = A - P

Here

P= 2200, r = 3% = 0.03 , n = 6 years

A = 2200 (1+0.03)^6=2626.92

Hence the interest earned = 2626.92-2200 = $426.92

Now if the total of $2200 was deposited in three banks then each account earns \frac{426.92}{3}= 142.31

Each account earns $142.31

When the p-value is used for hypothesis testing, the null hypothesis is rejected if _____
pashok25 [27]

Answer:

B

Step-by-step explanation:

Here, we are to give the reason why we would reject the null hypothesis during the hypothesis testing.

In considering whether to accept the null hypothesis or reject the null hypothesis, we have to take into consideration two things.

The p-value and the alpha value. The p-value refers to the probability which is directly obtainable from the standard score which is referred to as the z-score while the alpha refers to the level of significance.

Now, when the p-value is less than alpha, we simply reject the null hypothesis and accept the alternative hypothesis. In a case however, we have the value of p greater than or equal to the significance level alpha, we simply accept the null hypothesis in this case.

The question asks for a rejection case and this can happen only when the p-value is less than the level of significance alpha

A company makes electronic gadgets. One out of every 50 gadgets is faulty, but the company doesn't know which ones are faulty un
Talja [164]

Answer:

Yes, the company can expect a profit in the long term

Step-by-step explanation:

In this question, we are to project if a company is expected to make a profit or loss given the information in the question.

Let’s use the scenario of 50 gadgets produced.

1 is expected to be faulty, while 49 is thus expected to work perfectly.

Now, on this 49 sold, there is an expectancy of $3 profit. Hence, this means that for a batch of 50 gadgets produced, the amount of expected profit will be 49 * 3 = $147

The amount that would be used to repair the faulty unit is $80. If we subtract this from the total expected profit, we have $147-$80 = $67

Hence, per 50 gadgets sold, a total of $67 in profit is to be expected

This means profit is expected in the long tey
