Answer: 14
Step-by-step explanation:
We arrange the number as -3, 1, 7, 8, 18, 19, 42, the old median is 8.
But the median has change to 11 when the number is add, which means that the number is between 7 and 18.
(8 + x)/2 = 11 Where x is the new number
8 + x = 22
x = 14
Answer:
I can help you with 1, 2 and 3.
Step-by-step explanation:
1. 2x + 3y = 1470
Subtract 2x from both sides: 3y= -2x+1470
Divide three from both sides: y= \frac{-2}{3}x +490
2. To graph it, you would first go to (0,490) because that is where the y-intercept is. Since slope is ride over run, you can either go up 2 left3 or down 2 right 3. You can proceed doing that until you have enough points to draw the line.
3. f(x)= -2/3x +490. This function means represents how many wraps are sold based on how many rolls are sandwich.
Answer:
The correct answer is B
Step-by-step explanation:
Both of their medians are equal and Ami's range is larger than Lolo's range :)
Answer:
1050 units
Explanations:
Given the equation y=500+0.2x to determine his weekly paycheck based on his sales volume, where:
y is the amount of his check
x is the number of units he sells each month.
In order to determine the amount of units he would need to sell for his paycheck to be $710, we willl substitute y = 710 into the equation and find the value of x as shown:
y=500+0.2x
710 = 500+0.2x
710-500 = 0.2x
210 = 0.2x
0.2x = 210
Divide both sides by 0.2
0.2x/0.2 = 210/0.2
x = 1050
Hence he would need 1,050 units to sell for his paycheck to be $710
