Answer: 11x-6
Steps:
(2x+ 1/2) + (9x - 6 1/2)
-1/2. -1/2
2x+9x-6
11x-6
So the final answer is 11x-6
Answer:
There are 10 stripes in the blanket.
Step-by-step explanation:
We are given the following in the question:
Length of blanket = 2 meters
1 meter = 10 decimeter
Length of blanket in decimeter =
Change of color = Every 2 decimeters.
Number of stripe =
Thus, there are 10 stripes in the blanket.
Answer:
d
Step-by-step explanation:
simply look between 8 and 10
3b because b^2-4= 1/b. So 2/1/b= 2b b+2b = 3b
1st Step - Find the mean (average):
245 + 300 + 325 + 465 + 100 = 1435
1435/5 = 287 ( mean)
2nd step find the sun of the sqaure the difference between the gievn data and the mean
287 - 245 = 42^2 = 1,764
300 - 387 = 13^2 = 169
325-287 = 38^2 = 1,444
465 - 287 = 178^2 = 31,684
287 - 100 = 187^2 = 34,969
1,764 +169 + 1,444 + 31,684 + 34,969 = 70,030
Now divide that by the number of samples minus 1 ( 5-1=4)
70,030 / 4 = 17,507.5
The variance = 17, 507.5
