Please reference the attached diagram.

Set the compass to a radius greater than half the distance between X and Y
Mark arcs on either side of the segment XY using X as a center
Mark arcs on either side of the segment XY using Y as a center
Draw a line (JK) between the points where the arcs intersect. This is your perpendicular bisector.

What graph represents f(x) = 0.5(4)x

vampirchik [111]

Answer:

See attached picture

Step-by-step explanation:

The equation f(x) = 0.5(4)x is most likely $f(x) = 0.5(4)^x$ . This is an exponential. To graph the function, test the points -1, 0, and 1. Then connect.

$f(x) = 0.5(4)^{-1}=0.5(\frac{1}{4}) = \frac{1}{8}$

$f(x) = 0.5(4)^{0}=0.5(1) = 0.5$

$f(x) = 0.5(4)^{1}=0.5(4) = 2$

Solve for variable: 2(r-3)/4 -8 =50

kompoz [17]

Hello!

Let's begin by multiplying all 3 terms by 4, to remove the fraction:

2(r-3) - 8(4) = 50(4)

Then 2r - 6 - 32 = 200. Consolidating the constants on the right side, we get:

2r = 162. Solving for r, we divide both sides by 2, obtaining r = 81 (answer)

100 POINTS!!!!! AND BRAINLIEST!!!!!!

Answer:

x = 6/3y+1

Step-by-step explanation:

x+3xy=6

Step 1: Factor out variable x.

x(3y+1)=6

Step 2: Divide both sides by 3y+1.

x(3y+1) / 3y+1

so x = 6/3y+1

11. If you rolled a six-sided die 242 times, how many times would you expect an odd number to appear?

Ilia_Sergeevich [38]

The numbers on a six sided die are 1, 2, 3, 4, 5, 6.

Odd numbers are numbers that cannot divide 2 completely. Thus, the odd numbers here are 1, 3 and 5

Probability is expressed as

Number of favourable outcomes/total number of possible outcomes

The total number of possible outcomes is 6

The number of favourable outcomes is 3

Thus, the probability of rolling an odd number is

3/6 = 1/2

Thus, if the die is rolled 242 times, then the number of times you would expect an odd number to appear is

1/2 * 242 = 121 times
