Answer:

5/51 or 9.8

Step-by-step explanation:

Since she does not put the marble back it's dependent.

1/3 chances the first marble is red and 5/17 the second is too.

Multiply and you get 5/51 odds, or approximately 9.8% chance

Answer:

1/9.

Step-by-step explanation:

Prob(First marble is red) = 6/18 = 1/3

Prob(Second marble is red) = 1/3

Required probability = 1/3 * 1/3 = 1/9.

8.)What is the Measurement of angle 2?<br><br> 9.) What is the measure of angle 7?
EastWind [94]

Answer:

angle 2 = 90° {corresponding angles}

angle 7 + angle 5 = 180° {linear pair}

or, angle 7 + 100° = 180° {angle 5 is corresponding to 100°}

so, angle 7 = 80°

Which expression is equivalent in to the given expression? Assume the denominator does not equal zero.
marusya05 [52]

The equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4

<h3>How to determine the equivalent function?</h3>

The expression is given as:

14r^4y^6/7r^8y^2

Start by dividing 14 by 7

2r^4y^6/r^8y^2

Next divide y^6 by y^2

2r^4y^4/r^8

Lastly divide r^4 by r^8

2y^4/r^4

Hence, the equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4
