Answer:

3/6 or 1/2

Step-by-step explanation:

There are 2 even numbers on the spinner. It would be 2/4 or 1/2 for the probability the spinner will land on one of the numbers. The coin is a 1/2 probability you will land on tales. If you add both sides of the coin and the 4 numbers on the spinner you would get 6. You would then add only the even and tales together. That would be 3 out of 6.

Their is a 50% chance for both events cause

For numbers

their is 2 even and 4 total numbers

2/4 = 1/2 which is 50%.

For coin

Their is 1 take and 2 sides

1/2=50%

Explain how you can find whether 5/6 or 5/8 is greater

ratelena [41]

Because The Smaller The Denominators The Bigger The Fraction Pieces So The Denominators With 6 And 8 The Six Is Smaller So The 5/6 Will be Greater Than 5/8 .

Hope This Helps :)

Which of the sets of ordered pairs represents a function?

IgorC [24]

Answer:

Neither set A nor set B represents a function.

Step-by-step explanation:

According to the definition of a function, for each input there exists a unique output. In other word for each value of x there exists unique value of y.

In set A we have four ordered pair (-4,5),(1,-1),(2,-2) and (2,3).

It means for x=2, we have two values of y, i.e., -2 and 3.

Since for a single value of x there exist more than one value of y, therefore set A is not a function.

In set B we have four ordered pair (2,2),(3,-2),(9,3) and (9,-3).

It means for x=9, we have two values of y, i.e., -3 and 3.

Since for a single value of x there exist more than one value of y, therefore set B is not a function.

SOLVE x^4 − 15x^2 − 16 = 0 <br> What are the roots of the equation?

kakasveta [241]

Answer:

roots : 4, -4, i, -i

Step-by-step explanation:

This gets a bit tricky.

We have to substitude x^2 as u in this problem.

Now to rewrite x^4 − 15x^2 − 16 = 0 with u, we get

u^2 - 15u - 16 = 0

( u - 16) (u + 1)

U = 16

U = -1

<em>This is not the end of the problem. </em>

Now we have to substitute x^2 back to u.

x^2 = 16 --> we get the roots 4 and -4

x^2 = -1 --> we get the roots i and -i

Please help me i need to solve for RS

Sonbull [250]

Answer:

Step-by-step explanation:

RV=VU and SW=WT ⇒ $VW=\dfrac{RS+UT}{2}$

So:

$3x+5=\dfrac{2x+15+6x-37}{2}\\\\3x+5=\dfrac{8x-22}{2}\\\\3x+5=4x-11\\^{\qquad-5\qquad-5}\\3x=4x-16\\^{-4x\qquad-4x}\\-x=-16\\^{\div(-1)\quad\div(-1)}\\x=16\\\\RS=2x+15=2\cdot16+15=32+15=47$
