Step-by-step explanation:
i used the pythagorean theorem twice . . .
1st was with ΔCED:
EC² + 7² = 8²
EC² = 64-49
EC = √15
2nd was with ΔAED:
AE² + 7² = 10²
AE² = 100-49

a = 8m
b = 5m
c = ?
According to the Pythagoras theorem,
a² + b² = c²
8² + 5² = c²
64 + 25 = c²
89 = c²
c = 9.433
Rounding off,

Answer:
15) x = 10.2
16) x = 22.7 and y = 44.6
Step-by-step explanation:
15) tan 52° = 13/x
x = 13/tan 52°
16) sin 90°/50 = sin 27°/x
x = 50(sin 27°)
sin 90°/50 = sin 63°/y
y = 50(sin 63°)

An airline reports that 85% of its flights arrive on time. To find the probability that its next four flights into LaGuardia Airport all arrive on time, can we multiply (0.85)(0.85)(0.85)(0.85)? Why or why not?
Answer:
The answer is "no".
Step-by-step explanation:
No, because the probability besides simultaneous flights to arrive on time are not self-sufficient for every flight (when the first flight was late, therefore the probabilities during the next flight were significantly greater), because then the standard multiplication principle would be used for explanatory variables.
Yes, we can multiply (0.85)(0.85)(0.85)(0.85)
Let the four flight be represented by A, B, C, and D respectively
Probability that each of the flights arrive on time is 0.85
That is:
Probability that flight A arrives on time, P(A) = 0.85
Probability that flight B arrives on time, P(B) = 0.85
Probability that flight C arrives on time, P(C) = 0.85
Probability that flight D arrives on time, P(D) = 0.85
Probability that the next four flights arrive on time will be:
P(A) x P(B) x P(C) x P(D) = 0.85 x 0.85 x 0.85 x 0.85
Yes, we can multiply (0.85)(0.85)(0.85)(0.85)

What is the volume, in cubic inches, of a cone that has a radius of 8 inches and a height of 12 inches? Use 3.14 for π , and round to the nearest hundredth. if you answer this WITH NO LINK I will give extra points!
Answer:
803.84 in^3
Step-by-step explanation:
First of all we have to find the base area
base area = radius^2 x 3.14 = 8^2 x 3.14 = 64 x 3.14 = 200,96 in^2
the volume can be find with this formula:
V = (base area x height)/3
V = (200.96 x 12)/3 = 803.84 in^3

Explain what median is and how to solve for it
Answer: See below
Step-by-step explanation:
Median is the value that separates the higher data and lower data. In simple terms, it is the "middle" value of the whole set of data. There are two different ways to solve for the median.
1. If the data set has an odd number of values, line the values up in increasing order. Then the value or number that lies in the middle will be the median.
For example, if we are given a data set {1, 3, 4, 2, 5}. First, we line them up by increasing order, which becomes {1, 2, 3, 4, 5}. Since it is an odd number set, we can directly get the median which is 3.2. If the data set has an even number of values, line the values up in increasing order. Then there will be two number that lies in the "middle" together. We add them up and divide them by 2. The average of the two numbers will be the median of the set.
For example, if we are given a data set {2, 6, 4, 10, 8, 12}. First, we line them up by increasing order, which becomes {2, 4, 6, 8, 10, 12}. Since it is an even number set, we get our median from the two numbers in the middle, which are {6, 8}. We add them together to get 14 and then divide by 2 which is 7. So the median will be 7.Hope this helps!! :)

Write the number as a percent.
3/20
Answer:
15%
Step-by-step explanation:
not that hard just make it a decimal then at the point go back twice and there its 15%
Answer:
15%
Step-by-step explanation:
Since 100 isn't the denominator we need to make it a denominator.
3/20 x 1/5 = 3/100 we need to do the same to the denominator because whatever we do to the denominator has to do with the numerator 3 x 5 = 15,
15/100 means 15%!
