Answer:
probability of getting exactly 500 heads= 1
Step-by-step explanation:
If a coin is tossed, the probability of obtaining a head = 0.5
If a coin is tossed, the probability of obtaining a tail= 1- probability of obtaining a head
If a coin is tossed, the probability of obtaining a tail=1-0.5
If a coin is tossed, the probability of obtaining a tail=0.5
So if 1000 coin are tossed, the probability of getting exay 500 heads which is already the half of 1000 is 1
Answer:
g(x) = | x + 7 |
Step-by-step explanation:
The absolute value graph f(x)=|x| is a V-shaped graph with the vertex (tip, point) at (0,0). The graph shown has been translated (slid, shifted) 7 units to the left. Left or right shifts, horizontal shifts, are caused by an adjustment to the x. Horizontal shifts are also maybe the opposite of your intuition. Left shifts, you ADD to x. Right shifts, you subtract from x.
This is a left shift, so adjust the x by inserting a +7
f(x) = |x|
g(x) = | x + 7 |
Which of the following is the simplified form of [1] fifth root of x times the [2] fifth root of x times [3] the fifth root of x times [4] the fifth root of x?
That's
![( \sqrt[5] x)^4 = x^{\frac 4 5}](https://tex.z-dn.net/?f=%20%28%20%5Csqrt%5B5%5D%20x%29%5E4%20%3D%20x%5E%7B%5Cfrac%204%205%7D)
That looks like the second choice.
Let's write down what you said:
you double a number
2x
and then add 20,
2x+20
you get 4/7 of the original number.
2x+20=4/7x.
we can get rid of the fractionby multiplying everything by 7:
14x+140=4x
and subtract 4x from both sides:
10x+140=0
move 120 to the other side:
10x=-140
and divide by 10
x=-14
and that's the answer!
