Point M is on line segment LN. Given LN = 9, MN = 4x, and LM=5x
1 answer:
Answer:
MN = 4
Step-by-step explanation:
Given that L, M, N are collinear,
LN = 9,
MN = 4x
LM = 5x
Required:
Length of MN
SOLUTION:
To calculate the numerical length of MN, we need to find the value of x.
To find the value of x, generate an equation to solve for x as follows:
(segment addition postulate)
(substitution)
Solve for x
Divide both sides by 9
MN = 4x
plug in the value of x
MN = 4(1) = 4

Answer:
Option C. 2
Step-by-step explanation:
Let
x ----> the number of days
y ----> the internet charges in dollars
we have
This is a proportional relationship between the variables x and y
The slope of the linear function is equal to the constant of proportionality k
The unit rate is the same that the slope
so
The unit rate is $2 per day
therefore
The unit rate in the equation is 2
Answer:
C. The distribution of the value of transaction accounts is a right-skewed distribution.
Step-by-step explanation:
Some definitions
A skewed right distribution is one in which the tail is on the right side. On simple words we have most of the values on the left part of the distribution.
And present the following property:
A skewed left distribution is one in which the tail is on the left side. On simple words we have most of the values on the left part of the distribution.
And present the following property:
On a symmetric distribution we satisfy
For our case we have that and
And we can see that then we can conclude that this distribution is skewed to the right. And the best option would be:
C. The distribution of the value of transaction accounts is a right-skewed distribution.
