Answer:

<em>Statistic because the value is a numerical measurement describing a characteristic of a sample</em>.

Step-by-step explanation:

The complete question is

Determine whether the underlined number is a statistic or a parameter. A sample of employees is selected and it is found that <u>35%</u> own a television. Choose the correct statement below.

- Parameter because the value is a numerical measurement describing a characteristic of a population.

-Parameter because the value is a numerical measurement describing a characteristic of a sample.

-Statistic because the value is a numerical measurement describing a characteristic of a sample.

-Statistic because the value is a numerical measurement describing a characteristic of a population.

when the result is gotten from the population, the numerical measurement describing this result is known as the parameter. If the result is gotten from the sample(a fraction of the population), the numerical measurement describing this value is called a statistic.

From the question, the 35% was calculated from a selected sample of employers. The parameter would have been if the whole workforce in the country was actually analysed.

Louise has only 5 cent, 10 cent, and 20 cent coins in her purse. She has 30 coins in total, and she has two more 10 cent coins t
Hoochie [10]
Let x =  number of 5 cent coins.
Then there are (x+2) 10 cent coins.
Let y = 20 cent coins.
Total coins: x+(x+2)+y = 30
2x+y=28       
y = 28-2x                             (1)
Total value: 0.05x + 0.1(x+2) + 0.2y = 3.80
0.15x + 0.2y + 0.2 = 3.80
0.15x + 0.2y = 3.60             (2)
Substitute (1) into (2).
0.15x + 0.2(28-2x) = 3.60
-0.25x + 5.60 = 3.60
2.00 = 0.25x
8 = x

From (1), obtain y = 28 - 2(8) = 12
Answer: (x+2) = 8+2 = 10

Solve for X two questions
zloy xaker [14]

Answer:

Number 7 is 48

I think number 5 is 49 I'm not for sure about this one.

Step-by-step explanation:

Number 7:

Since it's a 90 degree angle, you just add 19 + 23 which gives you 42. Subtract 42 from 90 and it gives you 48, the value of the variable.

Number 5:

Now I'm not for sure about this one because of the number 12 pointing to the connecting point. So, I'd rather not say how I did this one before I get you confused when you learn about this in the future.
