Answer: C. a parameter.
Step-by-step explanation:
- In statistics, a parameter is a measure ( such as population mean , population proportion... ) generated from the entire population .
- A statistics is also a measure( such as sample mean , sample standard deviation , sample proportion,..) but generated from the sample taken from population.
Given : The Department of Motor Vehicles reports that 32% of all vehicles registered in a state are made by a Japanese or a European automaker.
Here, Department as considered the entire population of vehicles registered in a state are made by a Japanese or a European automaker to find the proportion.
Thus , 32% = Population proportion of vehicles registered in a state are made by a Japanese or a European automaker
So , The number 32% is best described as <u>a parameter</u>.
Hence, the correct answer is C. a parameter.
In this problem, you are looking at a pair of similar trapezoids. So we must be looking for a ratio between a side in the smaller trapezoid and the corresponding side in the bigger trapezoid. We are given the lengths of AB and EF, which we can use to find this ratio.
But before we do anything we must convert units so that all units are the same. Let's convert the 60 feet into inches. 60 feet is 720 inches.
Next, set up the ratio I mentioned earlier. If we set up the ratio so that it is smaller:larger, we would get 4:720, which simplifies to 1:180. Basically what this ratio says is that every 1 inch in the smaller trapezoid corresponds to 180 inches in the bigger trapezoid. Now we can use this ratio to find the lengths of the sides in the bigger trapezoid. Just multiply all the lengths of the smaller trapezoid by 180 to get the lengths for the bigger trapezoid. Finally, when we have all our side lengths, divide them all by 12 (because 12 inches in 1 foot) to get the measurements in feet.
From here, I'll let you find the total length yourself.
Answer: 422.5
Step-by-step explanation: To find how many mangoes were sold at 15.50 pesos, find 3/5 of the total number of mangoes. 3/5 of 25 is 15 because 3 (numerator) times 25 (mangoes) divided by 5 (denominator) is 15. 15 times 15.50 (price) is 232.5 pesos. Next we take the remaining mangoes (10) and multiply it by the price (19) to get 190 pesos. Add the sales and you get 422.5 pesos.
It would take 60 one hundred dollar bills to make 6,000
Imagine you have 4 'slots' on the stage:
_ _ _ _
In the first one there can be 1 out of 9 performers.
In the second - 1 out of 8 (because one has been already chosen).
In the third - 1 out of 7 (because two have been selected).
In the forth - 1 out of 6 (because three are already on the stage).
Total number of combinations is equal to: 9x8x7x6 = 3024
So the correct answer is D.
Hope it helps!
