Answer: mean=26 , median=24
Step-by-step explanation:
Mean=Sum of all values/number of values
mean= 30+39+24+ 19+18/5
= 130/5
mean=26
Median
arrange data in order
18,19,24,20,39
In the case of ungrouped odd-numbered data, the number that divided data into 2 equal parts is called the median.
so median=24
Answer: 4
Step-by-step exzplanation: 20/360= X/72
360X= 1440
Divide by 360
X=4
Answer:
x + 1
y = 9
Step-by-step explanation:
In order to solve this question we need to represent "y "in terms of "x" in the first equation, and the plug in the "y" value in the first equation into the second one. Luckily for us in the first equation it already shows what "y" is equal to in terms of "x" (based on the first equation y = -x + 10). Now we just need to plug in the value that we got instead of "y" in the second equation, and so we get....
y = 7x + 2
(plug in the y value and get the following ….)
-x + 10 = 7x + 2
(now just solve the following equation)
-x + 10 + x = 7x + 2 + x
10 = 8x + 2
10 - 2 = 8x + 2 - 2
8 = 8x
8/8 = 8x/8
1 = x
Now that we know the value of "x", all we need to do now is substitute the value of "x" into any of the equations and we will get the value of "y". So we do the following.....
y = 7x + 2
y = 7(1) + 2
y = 7 + 2
y = 9
