3 would turn into

<u>b= b^(6+8)</u>

b= ^(3+4)

b^14/b^7 or 1/2

4 would be

a^(14+10)  /  a(5+7)  

a^24  / a^12    or 1/2

Suppose the dial on the spinner is spun 2 times in a row.
Ivenika [448]

The probability of one success and one failure will be 4/9. Table C represents the probability distribution for the variable X.

<h3>What is probability?</h3>

The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,

The dials on the spinner are spun 2 times in a row.

P(dial lands on region)=P(success) = 2/3

P(failure) = 1/3

The probability that the two times dials on the spinner are not spun 2 times in a row.

P = (1/3)² = 1/9

The probability that the two times dials on the spinner are spun 2 times in a row.

P = (2/3)²= 4/9

One may calculate the probability of one success and one failure using the binomial distribution or by simply deducting the probabilities we previously determined from 1.

P = 1 - 1/9 - 4/9

P = 4/9

The probability of one success and one failure will be 4/9.

Hence table C represents the probability distribution for the variable

X.

viva [34]

Answer:

B.

Step-by-step explanation:

x = small box

(small box + 5 ounces) = large box.

B shows:

x + (x + 5) = 27

Small box + (small box + 5 ounces) = 27 ounces.

Small box + large box = 27 ounces.

————————————————————

Why A and C are incorrect.

A describes:

x + 5x = 27

Small box + 5 multiplied by small box = 27

(5 multiplied by small box is equivalent to 5 small boxes.)

Small box + 5 small boxes = 27

C describes:

x + 5 = 27

small box + 5 ounces = 27

Large box = 27

(We know that a small box + 5 ounces is a large box)

What expression is equivalent to 2x^2+2x-4/2x^2-4x+2
Studentka2010 [4]

You need to factor the numerator and denominator...

(2x^2+4x-2x-4)/(2x^2-2x-2x+2)

(2x(x+2)-2(x+2))/(2x(x-1)-2(x-1))

((2x-2)(x+2))/((2x-2)(x-1))  so the (2x-2)s cancel out leaving

(x+2)/(x-1)
