Average of all positive Integers , when written in base 10 is 58.
given,4 digits base 3
smallest 1000 = 3^3 = 27
biggest 2222 = 2*27+2*9+2*3+2 = 802 digits base 6smallest 10 = 36biggest 1000-1 = 6^3-1 = 4095.
So the intersection of these is 36 to 80 , 80-36+1 = 45
sum of numbers from 36 to 80 = (45/2)(72+44) = 45/2*116= 45*58 = 2610 average = 2610/45 =58A more straight forward approach would be to say that of there are 45 numbers the median on is in the 46/2 = 23rd position.
In this case the median and the mean will be the same. 36+23-1 = 58.
The median is the middle number in a sorted, ascending or descending list of numbers and can be more descriptive of that data set than the average. It is the point above and below which half (50%) the observed data falls, and so represents the midpoint of the data.
Median is not dependent on all the data values in a data set. The median value is fixed by its position and is not reflected by the individual value. The distance between the median and the rest of the values is less than the distance from any other point.

one important point to remember is that just because a difference between two treatment groups is found to be statistically significant, it does not mean that the difference:
Researchers use a finding's Effect size to measure magnitude and reliability.
a difference in significance does not always make a significant difference.
One reason is the arbitrary nature of the p<0.05 cutoff. We could get two very similar results, with p=0.04 and p=0.06, and mistakenly say they’re clearly different from each other simply because they fall on opposite sides of the cutoff.
The second reason is that p values are not measures of effect size, so similar p values do not always mean similar effects. Two results with identical statistical significance can nonetheless contradict each other.
Effect size refers to the measure of the magnitude of the experiment's effect. In other words, effect size measures how important is the relationship between two variables. The larger the effect size, the stronger this relationship is. Moreover, when the effect size is large, you are more likely to be dealing with a relationship that has practical significance.

a. 21-51
b. -5__ _|−9|
|5|_________|-5|
d. |−1|___________|—8|
C.
We can complete the given statements as follows-
a. 21 < 51
b. -5< |-9|
c. |5| = |-5|
d. |−1|< |-8|
Let us look at each statement one by one-
a. 21_51
here, we can clearly see that 21 is smaller than 51, so we use the < sign.
Thus, 21 < 51
b. -5_|-9|
here, on the right hand side we have a modulus sign. The modulus sign implies that we take only the absolute value.
|−9| = 9
Now, if we compare -5 and 9, 9 is clearly greater.
Hence, -5< |-9|
c. |5|__|-5|
here, |5| = 5
and |-5| = 5
Thus, |5| = |-5|
d. |−1|__|-8|
Here, |−1| = 1
and |—8| = 8
And 1 < 8,
thus, |−1|< |-8|

Use what you know to try to solve the problem below. A scientist is using a tracking device to measure how fast a blue whale swims. Data from the device show that the whale swam at a constant rate for 5 minutes and covered 2.5 miles in that time. Make a graph showing the change in the whales distance over time. How far does the blue whale swim in 1 minute? this 25 mi: 5
The graph showing the change in the whales distance over time is given by y = 0.5x
How to solve an equation?An equation is an expression that shows the relationship between two or more numbers.
The standard form of a linear equation is:
y = mx + b
Where m is the rate of change and b is the y intercept.
Let y represent the total distance covered for x minutes.
Let the constant rate be m miles per minute. The whale swam at a constant rate for 5 minutes and covered 2.5 miles in that time. Hence:
2.5 = 5(m)
m = 0.5 miles per minute
y = 0.5x
In 1 minute:
y = 0.5(1) = 0.5 miles
The graph is given by y = 0.5x

A store marks up merchandise 27%. The original price of an item is $725. What will be the retail price?
Answer:
$168
Step-by-step explanation:
cause the store marks up the price by 115%
The original price of the item was $725
Store increases the margin by 27%
Let us assume the retail price to be x
To get the retail price we need to add the margin added by the store to the original price which is $725 in this case.
So,
x= 725 × 127/100
x= 92075/100
x= 920.75
Another method-
Let retail price be x
Since the original price of the item is $725
The store increases the price by 27%
Add 27% of $725 to the original price to get the retail price
725 × 27/100
= $195.75
Add 195.75 to the original price to get the retail price
x= 195.75+ 725
x= 920.75
The Retail price which will be charged by the store on the merchandise will be $920.75

In the parallelogram shown, AE = t + 2, CE = 3t − 14, and DE = 2t + 8. Parallelogram A B C D is shown. Diagonals are drawn from point A to point C and from point D to point B and intersect at point E. What is the length of line segment DB? 20 units 24 units 48 units 68 units
Answer:
48 units
Step-by-step explanation:
A parallelogram is a polygon with four sides. Opposite sides and opposite angles of a parallelogram are congruent.
The diagonals of a parallelogram bisect each other.
In parallelogram ABCD, AC and DB are the diagonals. Since the diagonals meet at E, hence:
AE = CE and DE = BE (diagonals of a parallelogram bisect each other).
Since AE = CE, hence:
t + 2 = 3t - 14
3t - t = 2 + 14
2t = 16
t = 8 units
Therefore DE = 2t + 8 = 2(8) + 8 = 24 units
DE = BE = 24 units
But DB = DE + BE
DB = 24 + 24
DB = 48 units
Answer:
The answer is 48 units

A right triangle follows the pythagorean theorem, a^2+b^2=c^2. C is the hypotenus. A combination found using this is 5, 12, and 13. To double check this, we know that the hypotenus is 2x+3, where x is the smallest leg.

A computer salesman makes $10 per hour and 0.5% commission on what he sales. If he works for 40 hours this week, and he sales $4,500 of computers, how much will he make total?
Answer:
Total income earn = $422.5
Step-by-step explanation:
Given:
Earning per hour work = $10
Total hour = 40
Commission = 0.5% on sales
Total sales = $4,500
Find:
Total income earn
Computation:
Income from hour work = $10 x 40
Income from hour work = $400
Total commission = 0.5% x sales
Total commission = 0.5% x $4,500
Total commission = $22.5
Total income earn = $400 + $22.5
Total income earn = $422.5

Mr. majors ordered six hot dogs and a bucket of popcorn at the concession stand. if the popcorn was $3.20 and the total was $18.20, what was the price of one hot dog?
Answer:
The price of one hotdog is $2.50
Step-by-step explanation:
You can first write this out as an equation to make it easier to solve.
Lets say that x= the price of a hot dog and y= the price of popcorn
The equation would be:
6x + y = 18.20
We know that y= 3.20 so we can subtract 3.20 from 18.20. That will leave us with 6x = 15
Then, we just have to divide both sides by 6 and our answer comes out as x = 2.50
Answer:
2.50
Step-by-step explanation:
18.20 - 3.20 = 15.00
15.00 ÷ 6(hotdogs) = 2.5
Add a 0 at the end: 2.50
So the cost of one hotdog is $2.50
( why does that hot dog cost that much ;-; )

(a) dimensions;
(b) perimeter of the field.
The dimensions are 156m and 65m
The perimeter is 442m.
What are the dimensions?The formulae that can be used to determine the dimensions when the ratio of the dimensions are given and the diagonal is given are:
h = [tex]\frac{H}{\sqrt{ 1 + r^{2} } }[/tex]
w = [tex]\frac{Hh}{\sqrt{ 1 + r^{2} } }[/tex]
Where:
h = height H = hypotenuse r = ratio of width to the height : 5/12 = 0.41667w = widthh = [tex]\frac{169}{\sqrt{ 1 + 0.41667^{2} } }[/tex] = 156m
w = [tex]\frac{(169 x 156)}{\sqrt{ 1 + 0.41667^{2} } }[/tex] = 65m
