-8+ -1 equals -9
2-7= -5
-8 x -2 equals 16
Answer: what is number 6?
Step-by-step explanation:
Because ΔABC' is 50% smaller than ΔABC
The sides of ΔABC' will be 50% smaller
Hence, AC' length is 3
He would have played 36 matches and gotten a grand total of 254 shots. If he was average then he would’ve gotten 255 shots in 36 games.
2 * 77 = 254
3 * 85 = 255
Answer:
2424.5
904.16
Step-by-step explanation:
the mean = ∑frequency /n
∑f = 5+17+36+115+125+81+47+45+22+7 = 500
∑xf = 1212250
∑x²f = 3347037625
sample mean = 1212250/500
= 2424.5
variance = 1/500-1[3347037625 - 1212250²]
= 815710.02
standard deviation is = √variance
standard deviation = √815710.02
= 904.16
