1000 coins are tossed find the probability of getting exactly 500 heads.
ipn [44]

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

Which is a translation of f(x)=|x|. Write the function rule for g(x)
eduard

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 |

An outdoor amphitheater has 100 seats in the front row and each subsequent row has 6 more seats than the previous row. how many
fiasKO [112]
If each row have 6 more seats than the previous, then there is a common difference of 6 seats. This, in turn, becomes an arithmetic progression, with a₁ being 100 and d being 6. Now, we want to know the total number of seats when n = 23, so we need to use the sum of an arithmetic progression form:

S_n = \frac{n}{2}(2a_1 + (n - 1)d)
S_{23} = \frac{23}{2}(2(100) + 22 \cdot 6)
S_{23} = \frac{23}{2}(200 + 132)
S_{23} = 3818

Hence, there are 3818 seats in the first 23 rows.

Which of the following is the simplified form of fifth root of x times the fifth root of x times the fifth root of x times the f
JulsSmile [24]

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}


That looks like the second choice.

If you double a number and then add 20, you get 4/7 of the original number. What is the original number?
liberstina [14]
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!
