Median = middle number
Total ten numbers so
median = (17 + b)/2
given median = 18
so
(17 + b)/ 2 = 18
17+b = 36
b = 36 - 17
b = 19
Now you have the data set
7, a , 12, 15 , 17, 19, 20, 22, 24 , 25
Mean = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24 +25)/ 10
Given mean = 17
so
17 = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24 +25)/ 10
17 = (a + 161) / 10
a + 161 = 170
a = 170 - 161
a = 9
answer
a = 9
b = 19
Answer:
Hello Love!
All range is in math Is the highest number subtracted by the smallest number so our equation is 15 - 0 = 15
so 15 is our range!
Answer:
y= 5x/7 -27/7
if they are parallel there gradient is the same
m1=m2
y-y1=m(x-x1)
plug in the gradient and points E
y-(-3)=5/7( x-4)
y= 5/7(x) -20/7 +3
final answer
y= 5/7(x) +1/7
Step-by-step explanation:
F(x)=2x
but x= 4
F(x)= 2(4)
F(x)= 8
1/8 is same as 8
0.125
When comparing two numbers, you usually start by comparing the numbers on the left of the decimal point, if you find one of them greater than the other, then you've got your answer ready. If the numbers on the left of the point are equal, then you start comparing the decimal part.
In the two numbers given, we have 87 and 13.688. We start by comparing the numbers before the point, we will find that these numbers are 87 and 13.
Comparing these two, we can see that 87 is greater than 13.
Therefore: 87 is greater than 13.688
