Step-by-step explanation:

Statistical questions are questions which can have a variety of answers, explanations & justifications.

Fpr example, asking the weather report to people from four different countries in four different continents is a statistical questions as their answers can vary.

$\rule{150pt}{2pt}$

Now, in the above question, the questions are asked to 205 students from the same school & same grade.

A) Since the students belong to the same grade and the same school, there will be no difference in the timings of their second period class. So, this question is non-statistical question.

B) Height among students can vary even if they're of the same age or gender. Since this question can have various answers, it's a statistical question.

C) The word given is 'STATISTICAL' & it will always have eleven letters in it. It's a non-statistical question .

D) The students in the survey all belong to the same school. So, all of the answers will be the same & it'll be a non-statistical question.

$\rule{150pt}{2pt}$

So, the correct answer is → B) What is your height measured to the nearest inch?

Caleb is putting tile down in his bathroom and needs to know the perimeter of the floor. Two sides rectangular floor are 5 1/3 f

ladessa [460]

Answer:

20 1/6 ft

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides:

2×(5 1/3 ft) + 2×(4 3/4 ft) = 10 2/3 ft + 8 6/4 ft

= 10 2/3 ft + 9 2/4 ft . . . . change 6/4 ft to 1 1/2 ft

= 10 8/12 ft + 9 6/12 ft = 19 14/12 ft . . . . . use common denominator of 1/12 ft

= 20 2/12 ft . . . . . . change 14/12 ft to 1 2/12 ft; next reduce that fraction

= 20 1/6 ft . . . . perimeter of Caleb's bathroom

A bicycle store costs $3850 per month to operate. The store pays an average of $40 per bike. The average selling price of each

11111nata11111 [884]

Answer:

The net profit per bike is 150-40= 120. Hence to break even, the store needs to profit more than the operating cost of the store. 3840/ 120= 32. The store needs to sell 32 bicycles each month to break even.

PLZ HELP MARKIN BRAINIEST!!!

Lady_Fox [76]

Answer:

Step-by-step explanation:

The first question is asking you how many visitors there were, using the function model provided, when x = 0. Filling that in gives you:

$y=18,582(.90)^0$

Anything to the 0 power = 1, so

y = 18,582(1) and

y = 18,582

The second question is asking you how many visitors there were on the 9th weekend, when x = 9:

$y=18,582(.90)^9$ and

$y=18,582(.387420489)$ so

y = 7199

The last question is asking on what weekend (unknown x) are there

y = 15.051 visitors. That requires using a log to solve for x. Set it up first:

$15,051=18,582(.90)^x$

Start by dividing both sides by 18,582 to get:

$.8099773975=(.90)^x$

Now we need to take the log of both sides to get that x out from its exponential position. By taking the log of the right side, we are given the ability to bring the x down in front:

log(.8099773975) = x log(.90)

Now divide both sides by log(.90) to get

x = 2.000

That means that on the second weekend, there were approximately 15,051 visitors.
