With replacement, each draw has a probability of
9 pink out of 18 total number of chips.

Therefore, by the multiplication rule, the probability of having both draws picking a pink is
P(pink,pink) = (9/18)*(9/18) = 81/324 [ = 1/4 ]
or
P(pink,pink) = $\frac{9}{18}*\frac{9}{18}=\frac{81}{324}$

7.3 * 10^7 in standard form is 73,000,000
73,000,000 subtracted by 9,980,000 is 63020000.

Which graph shows a proportional relationship between x and y? Please help me explain it and what's the answer A,B,C,D

Vesna [10]

Every proportional relationship is an equation like y = a number times 'x'. When you graph that equation it's a straight line that goes through the origin and every point on the line satisfies the equation. Line B is the only graph that looks like that. The others all have a piece of a proportional relationship. Their bottom pieces are proportional relationships but then they break and the top pieces are not.

The measure of one angle is 130 which statement is true regarding the 130 angle and angle 3

Dafna11 [192]

According to Figure that is shown below, the correct answer for this problem is:

<span>B. They are alternate interior angles, so angle 3 also measures 130°.

</span>The same happens with 7 and 11. This is an obtuse angle, that is, this kind of angles measures more than 90° but less than 180°.
