Anna truncated the decimal expansion of x to find the best approximation. On a number line, the location of x is between 10.9 an

podryga [215]

Answer:

Well to estimate a decimal the best option would be to round it to.

10 or 11 (For 10.9)

11 (For 11.1)

and since two of them equal 11.

The estimation would be 11.

I hoped this helped.

Use the regression calculator to compare the teams’ number of runs with their number of wins. a 2-column table with 9 rows. colu

The equation of the trend line is ŷ = 0.15x - 23.21

<h3>How to determine the average rate of change of the trend line?</h3>

The points are given as:

hr =>808, 768, 655, 684, 637, 619, 613, 609, 563

w => 93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

Sum of X = 5956
Sum of Y = 680
Mean X = 661.7778
Mean Y = 75.5556
Sum of squares (SSX) = 50569.5556
Sum of products (SP) = 7547.1111

The regression equation is represented as:

ŷ = bX + a

Where:

b = SP/SSX

b = 7547.11/50569.56

b = 0.14924

a = MY - bMX

a = 75.56 - (0.15*661.78)

a = -23.20961

This gives

ŷ = 0.14924X - 23.20961

Approximate

ŷ = 0.15x - 23.21

Hence, the equation of the trend line is ŷ = 0.15x - 23.21

Solve the following equation show your work 3{-x + (2x + 1)} = x - 1

Reika [66]

Answer:

x = -2

Step-by-step explanation:

For this problem, we must simply solve for x. To do this, we will need equation operations, and the use of the distributive property.

Let's work this line by line until we have the value for x:

3{-x + (2x + 1)} = x - 1

3*-x + 3*(2x + 1) = x - 1

-3x + 6x + 3 = x - 1

3x + 3 = x - 1

2x = -4

x = -2

Now we can check our answer for x by plugging back into the original equation and see if the left hand side is equal to the right hand side:

3{-x + (2x + 1)} = x - 1

3{-(-2) + (2(-2) + 1)} ?= (-2) - 1

3{2 + (-4 + 1)} ?= -3

3{2 + (-3)} ?= -3

3{-1} ?= -3

-3 == -3

Thus, we have found the solution for x to be equivalent to negative 2.

Cheers.

What are the characteristics of pie chart?

anygoal [31]

In a pie chart, the arc length of each slice (and consequently its central angle and area) is proportional to the quantity it represents.

The characteristics of pie chart.

<h3>What do you mean by chart?</h3>

A chart is a graphical representation for data visualization, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart". A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info.

Given that:

A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area) is proportional to the quantity it represents.

The pieces of the graph are proportional to the fraction of the whole in each category.

Each slice of the pie is relative to the size of that category in the group as a whole.

mars1129 [50]

We know that

<span>Each pie was cut into six slices
</span><span>there are a total of 48 pieces-----> divide by six to find the number of pies
48/6----> 8 pies

</span><span>Two of the pies will be served to members of the department as courtesy
</span>so
subtract 2 to the total of pies to find the pies available for sale
<span>whole pies available for sale=8-2-----> 6 pies

the answer is
6 pies</span>
