tekilochka [14]

The manager at a golf course found that the population mean length of the holes at the golf courses is 415.9 yd. In this​ context, is the number 415.9 a parameter or a​ statistic?

Answer: The number 415.9 is a parameter because it represents the population characteristic.

<u>Explanation:</u>

Parameter: Parameters are numbers that summarize the entire population. For example the population mean summarizes the entire population, similarly population standard deviation describes the characteristic of entire population.

Statistic: Statistic are numbers that describes the sample. For example, the sample mean summarizes the sample which is drawn from the population, similarly the sample standard deviation describes the characteristic of sample.

Therefore, the population mean length of the holes at the golf courses (415.9 yd) is parameter.

Answer:

$3,000 was invested in the account that gained 13%

$17,500 was invested in the account that lost 10%

Step-by-step explanation:

Let the amount in both accounts be x and y

x for the first and y for the second

Adding both is 20,500

x + y = 20,500 •••••(i)

First account earned 13% profit

= 13/100 * x = 0.13x

Second account, a loss of 10%

= -10/100 * y = -0.1y

Total loss of -1,360

This is;

-0.1y + 0.13x = -1,360 •••••••(ii)

From i, x = 20,500-y

Insert this into ii

-0.1y + 0.13(20,500-y) = -1,360

-0.1y + 2665 -0.13y = -1360

-0.23y = -1360-2665

-0.23y = -4025

y = -4025/-0.23

y = 17,500

To get x, we have

x = 20,500 -y

x = 20,500- 17,500

x = 3,000

Jasmine makes $23 an hour; her boss tells her that she is receiving a 10 percent raise next month. What will her new salary be n
Naily [24]

Answer:

$986.70, $89.70

Step-by-step explanation:

New salary = Original salary + increase = $23/hr + 0.10($23/hr) =

$23/hr + $2.30/hr = $25.30

At $23/hr, Jasmine would earn ($23/hr)(39 hrs), or $897 for a 39-hr week.

At $25.30/hr, she would earn ($25.30/hr)(39 hrs), or $986.70.

This latter amount constitutes an increase of ($986.78 - $897), or $89.70.
