Answer:
(3 1/3 (3 2/5 (3 1/2 (3 2/3 (3 4/5 (3 5/6
Step-by-step explanation:
Here is a pro tip! When taking 10% of anything move the decimal back ONCE. The number you get is 10% of that number. You then take that number and subtract it by your original number if you want to know how much it will cost if it was 10% off.
The reason why that works is because to take 10% of something you would need to multiply it by 0.1, which is the same as 1/10 (which is also the same as dividing the number by 10).
So you take 10% of $6.00. It's $0.60.
Subtract that from your original amount.
$6.00
-$0.60
I'll let you do that one, but the answer comes out to be:
$5.40
Now to answer the question of this problem (the previous steps were if they asked for the price, but in this case you could've stopped at the 10% part)
You save $0.60.
Answer:
The skitties are not evenly distributed by colour
Step-by-step explanation:
Given that Mr. T aylor's 4th grade class uses Skittles to learn about probability. They open several randomly selected bags of Skittles and sort and count the different colors and want to determine if Skittles are evenly distributed by color.
(Two tailed chi square test)
If all are equally distributed then expected values would be equal to 420/5 =104
Observed Red Orange Yellow Purple Green Total
107 101 87 115 10 420
Expected 104 104 104 104 104 420
Chi square 0.0865 0.0865 2.7788 1.16345 84.9615 89.0769
Chi square is calculated as (obs-exp)^2/exp
Total chi square = 89.0769
df = 4
p value = <0.00001
Reject null hypothesis
The skitties are not evenly distributed by colour
I believe its asking to find X, Im sorry if Im wrong and its something else, the question confuses me.
1) x = 16
2) x = 16
3) x = 16
X always equals 16
____________________________
EXPLANATION
x/2 - 5 = 3
16/2 - 5 = 3
8 - 5 = 3
3= 3
x/2 = 8
16/2 = 8
8 = 8
x = 16
16 = 16
Marking me brainliest would be much appreciated! Im trying to get on the leaderboard
Answer:
it should be greater than 48 because 45.3 and 3.21 add up to 48.51 which is .51 greater than 48
