Management by exception:

1 answer:

5 0

Management by exception holds that only those issues that are significantly deviating from the normal course of action need to be looked at. If the deviations are minor or are likely due to random chance, then management does not need to worry about it at the time. None of the choices presented properly give this definition.

ANEK [815]

In hypothesis testing, one can only positively prove something by disproving the null hypothesis. I this case, the null hypothesis is that there is no relationship between eating frozen pizza and dangerous cholesterol levels.

A p value of a statistical summary (such as the sample mean difference between two compared groups) indicates the probability that the null hypothesis is true. Generally, a p value < 0.05 is usually taken to be statistically significant, i.e. a 5% chance that the null hypothesis is true. In this case, the relationship was find to be non-significant.

Assume the economy has a 12 percent chance of booming, a 4 percent chance of being recessionary, and being normal the remainder

elena-s [515]

Answer :

13.86%

Explanation:

Calculation of the Expected rate of return

First step

Expected return = (.12 x.187) + (.84 x.144) + [.04 x(-.12)]

Second step

Expected return =(0.02244)+(0.12096)+ (-0.0048)

Expected return=0.1386 ×100

Expected return=13.86%

Therefore the Expected return would be 13.86%

If 7000 dollars is invested in a bank account at an interest rate of 7 per cent per year, Find the amount in the bank after 14 y

Harlamova29_29 [7]

Answer:

1. Interest compounded annually = $18,049.74

2. Interest compounded quarterly = $18,493.77

3. Interest compounded Monthly = $18,598.16

4. Interest compounded continuously = $18,651.19

Explanation:

First let me state the formula for compound interest:

The future value of a certain amount which is compounded is the total amount (Principal + interest) on the amount of money, after compound interests have been applied, and this is shown below:

FV = PV $(1+\frac{r}{n} )^{n*t}$

where:

FV = Future value

PV = Present value = $7,000

r = interest rate in decimal = 0.07

n = number of compounding periods per year

t = compounding period in years = 14

For interests compounded continuously, the Future value is given as:

FV = PV × $e^{r*t}$

where

$e$ is a mathematical constant which is = 2.7183

Now to calculate each on the compounding periods one after the other:

1. Interest compounded annually:

here n (number of compounding periods annually) = 1

Therefore,

FV = 7,000 × $(1+\frac{0.07}{1})^{14}$

FV = 7,000 × $1.07^{14}$ = $18,049.74

2. Interest compounded quarterly:

here, n = 3 ( there are 4 quarters in a year)

FV = 7,000 × $(1+\frac{0.07}{4} )^{4*14}$

FV = 7,000 × $1.0175^{56}$ = $18,493.77

3. Interest compounded Monthly:

here n = 12 ( 12 months in a year)

FV = 7,000 × $(1+\frac{0.07}{12} )^{12*14}$

FV = 7,000 × $1.005833^{168}$ = $18,598.16

4. Interests compounded continuously:

FV = PV × $e^{0.07 * 14}$

FV = 7,000 × 2.66446 = $18,651.19

The standard costs and actual costs for direct materials for the manufacture of 3,000 actual units of product are as follows: St

svetoff [14.1K]

Answer:

$2,250 favorable

Explanation:

The direct material price variance is computed as;

= ( Standard price - Actual price ) × Actual quantity

Given that;

Standard price = $8.75

Actual price = $8

Actual quantity = 3,000 units

Direct material price variance

= ( $8.75 - $8 ) × 3,000

= ( $0.75 ) × 3,000

= $2,250 favorable

The economic significance of successful ticket scalping (scalpers sell tickets at higher than official prices) at baseball games

Vinvika [58]

Scalpers lead to the understanding that there is an overabundance of demand for tickets in comparison to the supply of tickets. With buyers willing to pay a premium for the scalped tickets, this can show that there is the ability for ticket prices to be raised and customers will still purchase them.
