M (Mean) = 20,500;
SD (Standard Deviation) = 55
1 ) 20,555 = 20,500 + 55 = M + 1 SD
Answer: 50% + 34.1% = 84.1%
2 ) 20.610 = 20,000 + 110 = M + 2 SD
Answer: 10% - ( 50% + 34.1% + 13.6% ) = 100% - 97.7% = 2.3%
3 ) 20,445 = 20,500 - 55 = M - 1 SD
Answer: 50% - 34.1% = 15.9%
Answer:
31.42 m
Step-by-step explanation:
10* π= 31.415( which can round to 31.42)
Answer:
the boys ate 2/6 more than the girls
Step-by-step explanation:
Subtract 10 from both sides
10 + x < 5
10 - 10 + x < 5 - 10
x < -5
So the answer is x < -5, or x is less than -5. Any number less than -5 would be the solution. Hope this helps!
Use ratios to solve
15 m/8 km = x m/50 km Cross multiply
15(50) = 8x
750 = 8x divide by 8 on both sides
93.75 = x
93.75 miles = 50km
