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
Answer: Choice A) y - 10 = 2(x - 3)
============================================================
Explanation:
We can rule out choices C and D because this diagonal line has a positive slope (as it moves uphill when moving to the right).
So m = 2 must be the slope.
---------
Recall that
y - y1 = m(x - x1)
represents the point slope form of a linear equation.
The point shown on this graph is (3,10) meaning that x1 = 3 and y1 = 10 pair up together.
So,
y - y1 = m(x - x1)
y - 10 = 2(x - 3)
which points to <u>choice A</u> as the final answer
Answer:
1.15 miles per minute was the balls average speed
Step-by-step explanation:
4 x 60 = 240 minutes
276 miles ÷ 240 minutes = 1.15 miles per minute
Answer.
Explanation. Let’s get all of the options down to the 1 ounce unit to determine the price per oz. we can do this by dividing the cost by the size.
0.79/10= 0.079 per oz
1.29/15=0.086 per oz
2.16/18=0.12 per oz
3.19/32=0.099 per oz
By looking at all of the options, we find that the 10 oz can has the lowest unit price. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.
Answer:
The jug will hold 4,800 milliliters.
Step-by-step explanation:
Each liter is 1000 milliliters, and 4.8 • 100 = 4,800
