To convey as an algebraic expression simply break down the statements and use any variable to represent the number in the sentence.
10 • x^2 = 40x
10x^2 = 40x
10x^2 - 40x = 0
10(x^2 - 4x) = 0
X(x - 4) = 0
X = 0
X - 4 = 0
X = 4.
Here are two possibilities of what the number can be, but because it is a nonzero number, I believe it would be 4.
I believe the normal distribution is symmetrical above and below
the mean. That tells us that in this kind of distribution, the mean
and the median are the same number ... 50% of the population
is below it, and 50% is above it.
So if the female Labs' weight actually follows a 'normal' distribution
with a mean of 62.5 lbs, then 2,700 of them weigh more than 62.5 lbs
and 2,700 of them weigh less than that.
The standard deviation doesn't matter.
Answer:
145
Step-by-step explanation:
Answer:
Option C is correct.
Step-by-step explanation:
We have been given total 8 data
Data is : 12,15,18,20,23,23,28
Here, n=7
Median is 
Median is 20.
When one data is added n=8
The median of even number of data is
Median is 
Median is 
4th terms is 20
5th terms is 23
Since, median should not be change hence,
Median will be 20.
Therefore, option C is correct.
Answer:
y= 0.25x +3
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept.
y= 0.25x -5
This equation is already in the slope-intercept form, hence we can easily identify its slope from the coefficient of x.
Slope= 0.25
Parallel lines have the same slope.
Thus, the slope of the line is also 0.25.
Substitute m= 0.25:
y= 0.25x +c
To find the value of c, substitute a pair of coordinates.
When x= 8, y= 5,
5= 0.25(8) +c
5= 2 +c
c= 5 -2
c= 3
Hence, the equation of the line is y= 0.25x +3.
