Answer:
C. $15,500
Step-by-step explanation:
The rate of change of the x values is 2
The rate of change of the y values is 1.
To continue this pattern:
x 38 40 42 44 46
y 12 13 14 15 16
If x = 45, y = $15,500
Answer:
x=237/7 and y=-199/7
Explanation:
Multiply the second equation by 2, then add the equations together.
(−2x+3y=−153)
2(x+2y=−23)
Becomes:
−2x+3y=−153
2x+4y=−46
Add these equations to eliminate x:
7y=−199
Then solve 7y=−199 for y:
7y=−199
(Divide both sides by 7)
y=−199/7
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−2x+3y=−153
Substitute −199/7 for y in−2x+3y=−153:
Add 597/7 to both sides
Divide both sides by -2
Answer:
y = 3x + 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 6x + 2y = 18 ( add 6x to both sides )
2y = 6x + 18 ( divide all terms by 2 )
y = 3x + 9 ← in slope- intercept form
Answer: Choice A
s = 10k + 6(5)
========================================================
Reason:
k = number of adults
10k = cost for all the adults (at $10 per ticket)
5 = number of children
6(5) = cost for all the children ($6 per ticket)
10k + 6(5) = total cost for all adults and children
s = total cost in dollars
s = 10k+6(5)
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.
