A statistics teacher found that the average quiz score in her class is 86%, and the average test score in her class is 81%.
Which of the following is the best way to represent this data?

A. using a bar graph where one has a length of 86 units and one bar has a length of 81 units

B. using a square with a side length of 86 units and a square with a side length of 81 units

C. using a pie chart with one section labeled 86% and one section labeled 81%

D. using a cube with a side length of 86 units and a cube with a side length of 81 units

Answers

Answer:

A. using a bar graph where one has a length of 86 units and one bar has a length of 81 units

Step-by-step explanation:

Took the quiz. The usual.

The optimal method to represent this data is with a "bar graph", with one bar 86 units long and the other 81 units long. which is the correct answer that would be an option (A).

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The best way to represent this data is using a "bar graph" where one bar has a length of 86 units and one bar has a length of 81 units.

This is because a bar graph is used to compare the sizes of different data points, and the length of each bar represents the value of the data point.

In this case, the average quiz score is 86% and the average test score is 81%, so the length of the bar representing the quiz score would be longer than the length of the bar representing the test score.

Thus, Option A correctly describes the use of a bar graph to represent the data, so it is the correct answer.

Which expression is equivalent to xy^2/9?

Answers

Answer:

Required

The equivalent expression (see attachment)

We have:

[tex]xy^\frac{2}{9}[/tex]

The quadratic equation that models the ball's height above the ground h, t seconds after it was thrown is given by :

[tex]h=-16t^2+108t+28[/tex] ...(1)

(a) For maximum height, put dh/dt = 0

So,

[tex]\dfrac{d(h)}{dt}=\dfrac{d}{dt}(-16t^2+108t+28)=0\\\\-32t+108=0\\\\t=\dfrac{108}{32}=3.37\ s[/tex]

Put the value of t in equation (1).

So,

[tex]h=-16(3.37)^2+108(3.37)+28\\\\h=210.24\ ft[/tex]

(b) When the ball reaches the ground,

h = 0

So,

Give an
example of a set of data that has more than one mode.

Answers

Answer:

Step-by-step explanation:

To calculate the mode, we simply count the number of times that each value appears in the data set and then find the value that appears most often.

A data set can have more than one mode if there is more than one value with the highest count. For example, both 2 and 3 are modes in the data set {1; 2; 2; 3; 3}.

Example of a set of data having more than one node is {1; 2; 2; 3; 3}.

What is Node?

An example S of the data type node. set is a subset of the nodes of a graph G. S is said to be valid for the nodes of G.

Use scientific notation to calculate the ratio and express your answer in standard notation. (round to the hundredths place)

Answers

Answer:

PE/SE = 5.02×10¹

Step-by-step explanation:

Sun-Earth (SE) = 93×10⁶ miles

Pluto-Earth (PE) = 4.67×10⁹ miles

so, PE/SE = (4.67×10⁹) / (93×10⁶) = (4.67×10³)/93 =

What is an
equation of the line that passes through the points (0, -1) and (6, 1)?

Answers

Answer:

y = 1/3x -1

Step-by-step explanation:

The slope is  y2 - y1 / x2 - x1

y2 is 1

y1 is -1

x2 is 6

x1 is 0

So it is 1 - (-1) / 6 - 0, or 2/6, or 1/3

The slope is 1/3.

The y-intercept is the place where x is 0. It shows the y-intercept here as

(0, -1),  The y-intercept is  -1

Slope form is y = mx + b. m is the slope, 1/3, and b is the y-intercept, -1

So the equation is: y = 1/3x -1

Step-by-step explanation:

180-55-55=70

180-70=110

180-110=70

70/2=35

Property: All straight lines from the centre of a circle are the same length, hence the triangles are isoceles.

Answer:  35 degrees

======================================================

Explanation:

Inscribed angle ABC = 55 subtends the minor arc AC which is 110 degrees (use the inscribed angle theorem).

The inscribed angle BDC subtends the minor arc CB, which we'll call x for now.

The two minor arcs (AC and CB) combine to form the arc ACB. Note how this is a semicircle since AB is a diameter. For any semicircle, the arc measure is 180 degrees.

So,

(arc AC) + (arc CB) = arc ACB

110 + x = 180

x = 180-110

x = 70

This cuts in half to 35 which is the inscribed angle BDC, again we're using the inscribed angle theorem here.
