The most you could have is 4:4
But the least is 0:4
Answer:
42,946.37
Step-by-step explanation:
you put it on a place value chart.Then you put the decimals in the correct spot.Finally you got your answer
Consider this option:
1. area_rombus=a*h, where a=6 - the length of the side, h - height.
h=area_rombus/a.
2. area_sq=a², where a=6 - the length of the square.
area_sq=36, area_rombus=4/5 *36=28.8.
3. according to the item 1 h=area_rombus/a=28.8/6=4.8.
answer: 4.8
Step-by-step explanation:
part1
the mean value is
(87+100+94+79+92+100+95+83+89+99+100+91+89+95+100+93+96+83) / 18
= 1665 / 18 = 92.5
part2
this is the sum of the absolute value of the differences bergen the individual sites and the mean value divided by the number of data points :
(5.5+7.5+1.5+13.5+0.5+7.5+2.5+9.5+3.5+6.5+7.5+1.5+3.5+2.5+7.5+0.5+3.5+9.5)/18
= 94/18 = 5.222222222... ≈ 5.2
part3
how many scores are less than 5.2 away (plus or minus) from the mean value ? in other words, how many differences in the part2 calculation were smaller than or equal to 5.2 ?
there are 9 scores meeting that criteria :
94, 92, 95, 89, 91, 89, 95, 93, 96
