Question 1

Solnce55 [7]

The probability to get heads on all three quarters is 1/8.

Step-by-step explanation:

Given data :

Leslie has three quarters.
Each quarters have 2 sides namely the Head and the Tail.

It can be determined that :

The total number of possible outcomes you can get from the three quarters with two sides = 2³ ⇒ 2×2×2 ⇒ 8 total outcomes.

If she drops all three of the quarters in the same time, there will be a total of 8 different outcomes.

These 8 outcomes include (T,T,T), (H,T,T), (H,H,T), (T,H,H), (T,T,H), (T,H,T), (H,H,T), (H,H,H).

From the above shown different possible outcomes, you need to find the probability that all three quarters will land on Heads.

Probability(3 heads)= No. of outcomes with 3 heads / Total no.of outcomes

We know that,

The no.of outcomes with 3 heads is only 1.
The total no.of outcomes is 8.

⇒ P( 3 heads ) = 1/8

The probability to get heads on all three quarters is 1/8.

Let y be inversely proportional to x. if x doubles, what happens to y?

Mila [183]

When it is said that a variable is inversely proportional to another, it is best to write out an equation to represent it.

This means;

y=k/x (where k is a constant number like 1 or 2, etc)

If you double x, the value of y is halved. I have attached a graph that shows this.

Hope I helped :)

How do you find what exponents of i are? like I know i^2 is -1, but how are you supposed to figure out i^26? do you have to writ

NeTakaya

Answer:

-1

Step-by-step explanation:

so "i" is the square root of -1 (√-1). We know that i² = (√-1)², and that when we square a square root we end back up with whatever is inside of the square root.

This is why i² = -1

We can find a pattern from writing out a few exponents:

i¹ = i

i² = -1

i³ = -i [(-1)(i)]

i⁴ = 1 [-1 · -1]

------

i⁵ = i [(1)(i)]

i⁶ = -1 [(i)(i)]

i⁷ = -i [(-1)(i)]

i⁸ = 1 [(-i)(i)= -(i²)= -(-1) = 1]

------

i⁹ = i [1 · i]

we can see that the pattern of i repeats every 4 numbers, so by dividing 26 by 4 (and finding the remainder), we can figure out which step of the pattern we are on

26 / 4 = 6 [remainder of 2]

we know that there is a remainder of 2, meaning that we are on the "second step" in the pattern: -1

you can do the same thing for any number

hope this helps!!
