35 + (-13) + 8 - (-6) = 22 + 8 - (-6) = 30 - (-6) = 36
Answer:
198.00
Step-by-step explanation:
I am not sure but I hope this helps some.
6 cm = 30m
find out how much meters 1 cm is equal too. Divide 6 from both sides
6cm/6 = 30,=m/6
cm = 30/6
cm = 5m
So for every centimeter, it equals 5 meters
You have 15 centimeter, so multiply 5 to it
15 x 5 = 75
75 meters is your final answer
hope this helps
assuming mean=0 and sd = 1; you want to find the z-score that corresponds to the first 20% of the graph.
The z-score is found in my "z-table" by subtracting 20% from 50% to obtain the distance away from the mean value.
When I look at the z-table in the back of the book, I want to find a number in the middle of the table that is closest to ".3000" (50% - 20% = 30%)
The closest value I find in the field is: .2995. I follow this out to the left (.8) and up to the top (.04) to get the numbers for the z-score: left+top. z-score = .84
This has to be evaluated for its placement. If the z-score is to the left of the mean; we negate it; if its to the right of the mean, we keep it a positive value.
20% is less than 50% so its to the left of our mean: z-score = -.84
Answer:
The answer to your question is Long = 10.39
Step-by-step explanation:
Data
hypotenuse = 12
long = ?
Process
1.- To find Long, we must use the trigonometric functions sine or cosine.
If we use sine, we use the 60° angle
If we use cosine, we use the 30° angle
a) sin 60 = long / hypotenuse
Long = hypotenuse x sin 60
Long = 12 x sin 60
Long = 10.39
b) cos 30 = Long / hypotenuse
Long = hypotenuse x cos 30
Long = 12 x cos 30
Long = 10.39
