Is "What is the area of the floor in this classroom?" a statistical question?

Mathematics

PSYCHO15rus [73]4 years ago

The answer is No

Explanation:

All statistical questions involve collecting numerical data (usually from a group of people) and then analyzing it to draw conclusions about the opinions of people of a certain phenomenon as the data varies depending on the response of each person. This process is not required to determine the area of the floor because this has a unique answer and can simply be found by measuring the height and width of the classroom and then multiplying both numbers. Also, this does not imply gathering a lot of data and the data does not vary.

In a sample of 150 cars, 18 cars failed a safety inspection. The sampling method had a margin of error of 0.02.
torisob [31]

Answer:

(0.10,0.14)

Step-by-step explanation:

-Given the sample size is 150 and our proportion is 18.

-We first determine the proportion's probability:

\hat p=\frac{x}{n}\\\\=\frac{18}{150}\\\\=0.12

-The interval estimate for the proportion is then calculated using the formula:

CI=\hat p\pm MOE\\\\=0.12\pm 0.02\\\\=[0.10,0.14]

Hence, the interval estimate is for the proportion (0.10,0.14)

Kevin caught some fish. Of them 4/9 were herring, and 2/9 salmon. What was the total amount of fish, amount of herring and amoun
julia-pushkina [17]

There were 3 different fish caught, Salmon, Herring and Flounder.

4/9 were Herring, 2/9 were Salmon, 4/9 +2/9 = 6/9

This means 3/9 were Flounders ( 3/9 + 6/9 = 9/9 = 1)

3/9 can be reduced to 1/3.

1/3 of the fish were Flounders.

Divide the amount of flounders by the portion caught:

12 / 1/3 = 12 * 3/1 = 36 total fish.

Now you have total number of fish, multiply the total by each portion for each type of fish.

Total fish = 36

Herring = 4/9 x 36 = 16

Salmon = 2/9 x 36 = 8

What is the x-coordinate of the vertex of the parabola whose equation is y = 3x2 + 9x?
inn [45]
Hello :
y = 3x²+9x
   = 3(x² + 3x )
   = 3 ( x² +2(3/2)x +(3/2)²) -(3/2)²)
   = 3((x+3/2)² -9/4)
y = 3 (x+3/2)² -27/4
<span>the x-coordinate of the vertex  is : - 3/2</span>
