10.

P(\text{ice skating}\mid\text{6th grade})=\dfrac{P(\text{ice skating AND 6th grade})}{P(\text{6th grade})}

155 of the total 545 students belong to the 6th grade. 46 of the total 545 students belong to the 6th grade and like ice skating. In terms of probability,

P(\text{6th grade})=\dfrac{155}{545}

P(\text{ice skating AND 6th grade})=\dfrac{46}{545}

So

P(\text{ice skating}\mid\text{6th grade})=\dfrac{\frac{46}{545}}{\frac{155}{545}}=\dfrac{46}{155}

11. Similar setup. We know 171 of 545 students like skiing, and there are 74 8th graders that like skiing. So

P(\text{8th grade}\mid\text{skiing})=\dfrac{\frac{74}{545}}{\frac{171}{545}}=\dfrac{74}{171}

The correct answers are (A) and (D) 

(A) = <span> (11 + 2.2) + (–5) = 11 + [2.2 + (–5)] 

(D) = </span><span>–7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)</span>

The ordered pair (1, -5) is a solution for the system x + 2y = -9 and x - y = 6.<br> true <br> false
sweet [91]
In an ordered pair, x is the first number and y is the second number. So this is telling you x=1 and y=-5. You can take this information and plug it into the formulas.

x + 2y = -9
1 + 2(-5) = -9
1 + -10 = -9? True

x - y = 6
1 - -5 = 6? *
1 + 5 = 6? True.

(*Subtracting a negative makes it a positive.)
