Answer:
X = 25
Step-by-step explanation:
We can calculate the value of x using Euclidean theorem
15^2 = 9 × x
225 = 9x divide both sides by 9
25 = x
I don't have a calculator near me... but you probably do. So just plug in those values for t.
Y = 4(-3) ^2 + 5
(Actually.. I might be able to do these in my head...) Y = 41
Y = 4(-1.5) ^2 + 5
Y = 14
Y = 4(0) ^2 + 5
Y = 5
Y = 4(1) ^2 + 5
Y = 9
Y = 4(4) ^2 + 5
Y = 69
The range is all the Y values. So it would be {41, 14, 5, 9, 69}
Answer:
its the second one hope this helps
Step-by-step explanation:
The answer is:
You shouldn't expect to get exactly 5000 heads, because you cannot predict precisely how many heads will occur.
The outcome in tossing a fair coin is based on chance.
However, according to the law of large numbers, the frequencies of events with the same likelihood of occurrence even out, given enough trials or instances.
For example, in the case of a fair coin, where both head and tail have equal probability of occurrence, as the number of tosses becomes sufficiently large (say 1 million tosses), the ratio heads to tails in the outcome will be extremely close to 1:1.
So according to the law, we should expect to approach a point where half of the outcomes are heads and the other half are tails, as the number of tosses become very large.
So, the triangle is a right-triangle and is an isosceles one, namely, it has twin legs, thus, check the picture below.
