Answer:

True

True

Step-by-step explanation:

The unknown parameters are treated as variable and data serve as coefficients. The random variables are value whose outcome depends on some random event. The θ can exist when n ≥ 0. A sample mean is a sequence which has normal distribution and n ≥ 1. The sample average of X-n follows normal distribution for all integer and n is greater or equal to 1.

makvit [3.9K]

Answer:

The solve of that problem is that Hernry invested $18.000 in stocks and $6.000 in bonds.

Step-by-step explanation:

First, to explain you have to do a multiplication about 6 on three. Like three times more than bonds, the result is 18. Then you have to do a  subtraction on $24.000 less $18.000, and the result is $6.000, so six is the amount on bonds. And is three times less than stocks, like the questions ask.

Banerjee Inc. wants to maintain a target capital structure with 30% debt and 70% equity. Its forecasted net income is $825,000,
bulgar [2K]

The capital budget will be supported with 30% debt and 70% equity. Since the company's income will be $825,000 this is the maximum equity that can be put towards the capital budget and therefor is matched in the ratio 70:30 by borrowings. If $825000 is 70%, divide that (825,000/.70) you’ll get the total maximum budget of $1,178,571 which is letter c. To get the 30%, just deduct the $825,000 to $1,178,571, you’ll get $353,571. To make sure your answer is correct, add up the 70% and 30% values and if they make the original total value, then the answer is correct. $825,000 + $353,571 = $1,178,571
