Answer:
80.88
Step-by-step explanation:
The mean is the average of the numbers. To calculate that, just add up all the numbers, and then divide by how many numbers there are. In other words it is the sum divided by the count.
95 + 45 + 37 .....
divided by 24 (the total number of numbers)
1,941 / 24 = 80.875
80.8<u>7</u>5 rounded to the nearest hundredth = 80.88
*
(hundredths place)
Rounding rule: If the digit to the right of the place you are rounding to is 5 or more, then round up to the next digit.
A) 2/4
b) i: 2/5*1/4= 2/20=1/10
ii:(3/5*2/4)+(2/5*3/4)=(6/20)+(6/20)=3/10+3/10=6/10
c) It seems like there is a lack of information on the tree diagram so I could not answer this.
Hope this helps :)
Sorry, I'm not sure if it's 3838 and 1616, or 38 and 16. So I'm doing both! ^.^
3838 × 1616 = 6,202,208 yards
38 × 16 = 608 yards.
Hope it helps.
Answer:
34.7 feet
Step-by-step explanation:
50.3 + 5 x 3 = 50.3 + 15 = 65.3
100 - 65.3 = 34.7
Answer:
Time taken to travel at 3 miles = 1.875
Time taken to travel at 5miles = 1.125
Total distance = 11.25
Step-by-step explanation:
D = speed x time
Time = distance/speed
Time at 3 miles per hour and 5 miles per hour
T1 = d/3
T2 = d/5
Total time = 3 hours
T1+t2 = 3 hours
d/3 + d/5 = 3
= d(1/2+1/5) = 3
d(5+3/15) = 3
d(8/15) = 3
We cross multiply
8d = 45
d = 45/8
= 5.625 miles
Total distance = 2d
2x5.625 = 11.25 miles
Since d is now known
T1 = 5.625/3 = 1.875 hours also 1 hour 52.5 minutes
T2 = 5.625/5 = 1.125 hours = 1 hour 7.5 minutes
Total distance 2xd = 11.25
