1 cm was multiplied by ten, so wee need to do that on the other side too.
1 times 10 = 10 cm, so 4 times 10 = 40 meters,
So your answer is 40 meters. Hope it helps!
Answer:
-4x + 12 = 20 is incorrect. she added 12 to 20 instead of subtracting 12 from both sides.
Step-by-step explanation:
It should have been, write problem
-4(x - 3) = 20
Use distributive property.
-4x + 12 = 20
subtract 12 from each side
-4x =8
divide each side by -4
x = -2
Answer:
107.50
Step-by-step explanation:
Given the following :
Midpoint (S)____F
S y 93 95 97 99 101 103 105 107 109 111 f 19 25 38 17 12 10 5 4 4 2
Calculating the mean and standard deviation using a calculator :
The mean(m) of the data above = 98.12
Standard deviation (sd) = 4.02
Proportion = 99% of population
From z table = 2.33
Using :
Zscore =(x - m) / sd
2.33 = (x - 98.12) / 4.02
2.33 * 4.02 = x - 98.12
9.3666 = x - 98.12
9.3666 + 98.12= x
x = 107.4866
X = 107.50
Answer:
$395.83
Step-by-step explanation:
to solve, we first need to subtract what we already have, first the scholarship, wich is a set amount being taken from the original amount
12'000 - 2'500 = 9'500
now we have the second subtracting factor, but this one isn't set in stone and defined, it is half of the amount his parents will pay, so what we can do is divide what we have by two, wich will give us 2 halves
9'500 / 2 = 4'750
now all we have to do is divide again but this time for each month that Daniel needs to save up in, in this case 12
4'750 / 12 = 395.83 (note1)
and there we have it, that is the minimum amount Daniel would save each month
note1: (3 goes on for infinity, usualy this is represented by a line above the repeating number, this is the case of a repeating decimal)
C) will not effected (the most frequent is still 600$)
