well, let's split the hours to 7 and 45 minutes and 1 and 26 minutes.
adding the hours we get 7 + 1 = 8.
adding the minutes we get 45 + 26 = 71.
so the time will be 8 and 71 minutes, wait a second!!! 71 minutes is really 60 + 11.
so the time will be 8 hours + 60 minutes plus 11 minutes, or 8 hours + 1 hour plus 11 minutes, or 9:11.
STEP-BY-STEP SOLUTION:
Let original price = x
( 100% - 20% )x = $44
0.8x = 44
x = ( 44 / 80 ) × 100%
x = $55
Okay, so you are asking how they came up with 0.8 as shown in the 2nd line above which I will rewrite below:
0.8x = 44
The 0.8 refers to how much of x ( original price ) is left in the new price.
So, if:
x = 100%
Then:
New price = x - 20% = 100% - 20% = 80%
Now, to get 0.8 is as follows:
80% = 0.8
Answer:
There is significant difference between the proportions
Step-by-step explanation:
Given that the two statistics classes were asked if A Christmas Story is the best holiday movie.
Class I II Total
n 40 50 90
x 30 45 75
p=x/n 0.75 0.90 0.8333
H0: p1 =p2
H0: p1 ≠p2
(Two tailed test at 5% level)
p difference = -0.15
STd error for difference =
Z statistic = p difference/std error
=-4.0246
p <0.00001
Since p <0.05 we reject H0. There is significant difference between the proportions
At 0.01 level also p is less than alpha So same conclusion
Answer:
x=34
Step-by-step explanation:
2x =68
----------- (68 divided by 2 is 34)
2 2
x=34
<span>6/x-4+5/x u can make common denominator
</span>
6 / x - 4 x / x + 5 /x
the answer is 11/x - 4x / x
