Answer:
∠BEC, ∠CED83°139°90°Step-by-step explanation:
When it comes to angles in a plane, the whole is the sum of the parts.
The little square in the corner of angle BED tells you that is a right angle, so has a measure of 90°. (This is the answer to part 4.) It also tells you that any ray between EB and ED will divide this angle into two complementary angles--angles that have a sum of 90°. There is only one such ray, EC, and it divides angle BED into angles BEC and CED.
1. Angles BEC and CED are adjacent complementary angles.
__
2. The parts of angle AEC are angles AEB and BEC. Angle AEC is the sum of those parts:
∠AEC = 49° +34° = 83°
__
3. Angle AED is the sum of angle AEB and right angle BED:
∠AED = 49° +90° = 139°
__
4. As we saw above, the marking on the figure tells you ...
∠BED = 90°

What is a two-way frequency table?A two-way frequency table is a way of organizing and displaying data that shows the frequency of occurrences of two categorical variables.
In such a table, the rows represent one variable, the columns represent the other variable, and the cells show the number (or frequency) of times that each combination of categories occurs.
We have,
A two-way frequency table shows how many times each combination of two categorical variables occurs.
In the table, the rows represent the "play an instrument" variable, the columns represent the "are in band" variable, and the totals are shown at the end of each row and column.
The entries in the table represent the frequency, or the number of students who belong to each combination of categories.
In this case, the two variables are "play an instrument" and "are in band". Based on the given information, we can create the following table:
Thus,
The table that shows these data correctly entered in a two-way frequency table is:
In Band Not in Band Total
Play 15 10 25
Do Not Play 5 20 25
Total 20 30 50

Dekalbs current population is 3,500 and it is increasing by 40 people pr year. Sycamores current population is 12,040 and it is decreasing by 100 people every year
Q: Write expressions for each population if x represents the number of years
And What is the current population of dekalb?
Answer:
Dekalb: 3500+40x = F
Sycamores : 12,040 - 100x = F
Step-by-step explanation:
These expressions can be used to explain each population
X = number of years for both expression
F = Final population
Dekalb: 3500+40x = F
Sycamores : 12,040 - 100x = F
The current population if 3500 if no years have gone by, plug in the year of numbers for X to find final population after the amount of years.

Answer:
$1200 each month
Step-by-step explanation:
So Craig pays $720 each year, so he pays 720/12 = $60 each month
Since $60 is 1/20 of his monthly income, we multiply 60 by 20
60* 20 = 1200
Craig earns $1200 each month

How much more money do the employees from Hideaway Pizza make at
the end of the month than the employees at Red & Blue's? Round your
answer to the nearest hundredth.
Supposing linear functions for both cases, it is found that employees at Hideaway pizza make $250 more at the end of the month.
--------------------
The salary, in dollars, for x days of work at Hideaway pizza is of:
[tex]S_h(x) = 300 + 40x[/tex]
At Red & Blue's, it is of:
[tex]S_r(x) = 500 + 25x[/tex]
A month is 30 days, so, the salaries are:
[tex]S_h(30) = 300 + 40(30) = 300 + 1200 = 1500[/tex]
[tex]S_r = 500 + 25(30) = 500 + 750 = 1250[/tex]
1500 - 1250 = 250, thus:
Employees at Hideaway Pizza make $250 more at the end of the month.

How can you estimaite [tex]\sqrt 40.[/tex]
9514 1404 393
Answer:
√40 ≈ 6 4/13 ≈ 6.31
Step-by-step explanation:
The estimate by linear approximation starts with the recognition that ...
40 = 36 +4 = 6² +4
and the difference from 36 to the next square, 7² = 49 is 49-36 = 13.
The linear approximation to √40 is ...
√40 ≈ 6 4/13 ≈ 6.31
__
There are various methods for improving this approximation. Perhaps the fastest improvement is obtained using the "Babylonian method." The next iteration is the average of this value and 40 divided by this value.
(82/13 +40/(82/13))/2 = 6 173/533 ≈ 6.3246 . . . . accurate to 4 decimal places
_____
Additional comment
When you write the value in terms of a square and a remainder:
n = s² +r
then the above linear approximation of √n can be written as ...
√n ≈ s +r/(2s+1)
Using the idea that a square root can always be represented by a continued fraction, we can continue the fraction one more iteration to give a slightly better approximation:
√n ≈ s +r(2s+1)/(2s(2s+1) +r)
For the case at hand, this gives √40 ≈ 6+52/160 = 6 13/40 = 6.325, accurate to 3 decimal places. Additional iterations using the continued fraction idea can be had using ...
n'' = s + r/(s +n') . . . . . where n' is an approximation of the root and n'' is a better approximation. This does not converge as fast as the Babylonian method, but may be easier to calculate on some calculators.

Which is the most reasonable measure of central tendency for the data set?
mean
mode
range
median
Answer:
I think its range I dont know
Step-by-step explanation:
The mean is the maximum often used as a degree of critical tendency because it makes use of all values inside the information set to give you an average. For statistics from skewed distributions, the median is higher than the implied because it isn't motivated through extremely big values.
The correct option is A.
Which is a better measure of center mean or median?The median is normally a better degree than the middle whilst there are intense values or outliers because it isn't always stricken by the right numerical values of the outliers. The suggestion is the maximum common measure of the middle. The phrases “mean” and “common” are regularly used interchangeably.

Your business is looking into three contracting firms. Based on previous research, there is a 75% chance that company 1 will earn you $40,000. There is a 45% chance that company 2 will earn you $60,000. Company 3 has a 30%chance of earning you $80,000. It costs $20,000 to draw up legal paperwork for each company. How much profit or loss would you expect after this deal is done if you sign with all 3 companies?
$21,000 loss
$81,000 loss
$21,000 profit
$81,000 profit
there would be a $21,000 profit.
this is because of the equation:[tex]40,000(.75) + 60,000(.45)+80,000(.30)+(-20,000)(1)= 21,000[/tex]
I would expect a $21,000 profit if I sign with all 3 companies.
Given that my business is looking into three contracting firms, and based on previous research, there is a 75% chance that company 1 will earn me $ 40,000, there is a 45% chance that company 2 will earn me $ 60,000, while Company 3 has a 30% chance of earning me $ 80,000, and it costs $ 20,000 to draw up legal paperwork for each company, to determine how much profit or loss would I expect after this deal is done if I sign with all 3 companies, the following calculation must be performed:
((40,000 x 0.75) - 20,000) + ((60,000 x 0.45) - 20,000) + ((80,000 x 0.30) - 20,000) = X 30,000 - 20,000 + 27,000 - 20,000 + 24,000 - 20,000 = X 81,000 - 60,000 = X 21,000 = X
