Answer:
The answer is C: X = 3
Step-by-step explanation:
1128 feet = 1128/5280 miles
it travels at 1128/5280 miles per second
to convert to miles / hour we multiply by 3600
so speed of the bullet = (1128 * 3600) / 5280 = 769.1 mph to nearest tenth.
Answer:
Step-by-step explanation:
Find the midpoint of each frequency range, multiply that number by the frequency, sum up and divide by the total frequency.
This will give the mean number.
<u>The mean is:</u>
- [17*( 3 + 3.5)/2 + 21*(3.5 + k)/2 + 33*(k + 4)/2 + 54*(4 + 4.5)/2 + 15*(4.5 + 6)/2]/140 = 4.09
- 55.25 + 10.5k + 36.75 + 16.5k + 66 + 229.5 + 78.75 = 140*4.09
- 17k + 466.25 = 572.6
- 17k = 572.6 - 466.25
- 17k = 106.35
- k = 106.35/17
- k = 6.26
Note, I expected the value of k between 3.5 and 4. This is a bit of illogical outcome.
I misread it but it isn't too different
set .12/.45 = x/100
cross multiply to solve for x
change x from a % to a decimal (for example: 12%=.12)
and that should be it
Answer:
A, B, C, & E
Step-by-step explanation:
A) 19,456 ÷ 6 = 3,242
(2/3 is 0.666666666 etc)
B) 28,765 ÷ 13 = 2,212.692308...
C) 4,145 ÷ 3 = 1,381
(2/3 is 0.666666666 etc)
D) 4,165 ÷ 17 = 245
(Not bolded because it is not an answer)
E) 44,312 ÷ 16 = 2,769.5
C -> When dividing by three, if the first number's values do not add up to a multiple of 3 there will be a remainder. Example from your problem,
4,145 -> 4 + 1 + 4 + 5 = 14 -> 14 is not a multiple of 3, so there is a reminder
D -> No decimal / fraction, no remainder!
Have a nice day!
