Answer:
2290 steel balls weigh 3,180 grams so each ball weighs 1.3886462882
grams. If you had a 8.87 kilograms of those balls they would number
8,870 grams / 1.3886462882 = 6,388 steel balls
Step-by-step explanation:
Answer:
A=500
Step-by-step explanation:
for mylar for polygon Area =ap/2
where a =apathem,p =perimeter
A=10*100/2
1000/2
500=a
the perimeter is the square of all the sides of the given polygon =10 sides =100
Answer:
78%
Step-by-step explanation:
Given the stem and leaf plot above, to find the median percentage for boys in the German test, first, write out the data set given in the stem and leaf diagram as follows:
40, 46, 46, 47, 69, 70, [78, 78,] 79, 82, 87, 90, 90, 95
The median value is the middle value in the data set. In this case, we have an even number of data set which are 14 in number.
The median for this data set would be the average of the 7th and 8th value = (78+78) ÷ 2 = 156/2 = 78
Median for boys = 78%
Possible outcomes: 10C4 = 210 ( combinations - we choose 4 of 10 people )
Favorable outcomes: ( 2C1 ) · ( 8C3 ) = 2 · 56 = 112
Probability : 112 / 210 = 0.5333 ( or 53.33 % ).
