Answer:

How many brothers and sisters do people in our class have?

Students might suggest that we can ask how many siblings, or they might suggest we ask how many brothers, how many sisters and how many altogether.

The idea of asking about brothers and sisters separately allows for a deeper exploration of the data and a more in depth answer to our investigative question.

Answer:

600 minutes           ( 10 hours)

Step-by-step explanation:

   rate c = 1 job/30 min

   rate r = 1 job/40 mi  

     1 job / ( 1/30 + 1/40) =    1 / ( 7/120) = 17.14 minutes   per ruckload

17.14 * 35 trucks = 600 minutes

Considering the given table and the periodicity concept, it is found that the data set is not periodic.

The period of a function is given by the distance between it's repetitions.

An example of a periodic data-set with a period of 3 would be 1,2,3,1,2,3,1,2,3,...

In this problem, looking at the table, it is found that there are no patterns of repetitions, that is, the number of cars washed do not follow a repeated pattern, hence the data set is not periodic.

Using the normal distribution, it is found that there are 68 students with scores between 72 and 82.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given, respectively, by:

[tex]\mu = 72, \sigma = 10[/tex]

The proportion of students with scores between 72 and 82 is the p-value of Z when X = 82 subtracted by the p-value of Z when X = 72.

X = 82:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{82 - 72}{10}[/tex]

Z = 1

Z = 1 has a p-value of 0.84.

X = 72:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{72 - 72}{10}[/tex]

Z = 0

Z = 0 has a p-value of 0.5.

0.84 - 0.5 = 0.34.

Out of 200 students, the number is given by:

0.34 x 200 = 68 students with scores between 72 and 82.

Answer:

Your answer is [tex]\frac{19}{33}[/tex]

Step-by-step explanation:

That is kind of hard. I have used the internet to help create that repeating decimal to a fraction and got that as your answer.

Answer:

19/33

Step-by-step explanation:

There are two repeating decimals so divide 57 (repeating part)... by 100x minus x

57/100x -x

57/100x - x = 0

100x - x = 57

99x=57

x=57/99

Simplify:

x = 19/33

Answer:

perfect square trinomial methodIf a polynomial has three terms, x2 + 12x + 36, which factoring method can be considered? Summary: If a polynomial has three terms, x2 + 12x + 36, the perfect square trinomial method can be considered to find the factor of the expression.

Answer:

Take the base of the parallelogram to be 40 cm. 1,200 sine (36) = 40 * h. Divide both sides by 40. So, the height of the parallelogram is 17.63 cm.

n^2 + 3.

Step-by-step explanation:

4 7 12 19

Differences are 3 5 7   so this a quadratic sequence.

2nd difference = 2 2

So the first part of the expression is n^2

Terms:  4  7  12  19

n^2       1    4   9  16

Difference = 3 3 3 3 3

So the answer is n^2 + 3.

Answer:

y = 0.5x + 5

Step-by-step explanation:

Use the slope formula to find the slope of a line given the coordinates of two points on the line.

The slope formula is:

m = [tex]\frac{y{2}-y{1} }{x{2}- x{1} }[/tex] = [tex]\frac{y}{x}[/tex]

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Now let's fill in the formula with the points,

m = [tex]\frac{8-4}{9-7}[/tex]

Solve,

⇒ Y = 9 – 7 = 2

⇒ X = 8 – 4 = 4

m = [tex]\frac{8-4}{9-7}[/tex] = [tex]\frac{2}{4}[/tex]

Simplify,

⇒ [tex]\frac{2}{4}=\frac{1}{2}=0.5[/tex]

Therefore, the Equation of the line is y = 0.5x + 5.

Step-by-step explanation:

In this article, I will show you how to find the area of a circle and express your answer in terms of pi (π). First, you'll need to familiarize yourself with the formula for calculating the area of a circle:

A = π * r²

Let's define our variables:

A: area of the circle

π: pi (a mathematical constant that is approximately equal to 3.141492 . . .)

r: radius of the circle (the distance from the circle's center point to its edge)

Typically, to find the area of a circle, we would simply plug in the circle's radius for r and 3.141592 for π. If so, our answer would be a number.

Therefore, the answer is 16π.
