Answer:
Step-by-step explanation:
Complementary angles mean two two angles sum with equal 90 degrees. Therefore you would need to create an equation to solve for the value of x.
4x+3x+13=90
-13 -13
7x=77
/7 /7
X=11
Now plug in the value of x.
A=4(11) B=3(11)+13
A=44. B=33+13
B=46
Angle a is the smaller angle and measures at 44°
P(s) = 45/125 = 0.360
P(A&C) = 38/125 = 0.304
Probability that one is not in Arts and Crafts = 1- P(A&C) = 1-0.304 = 0.696
Therefore,
Probability that the child selected is in swimming when its known they didn't sign for Arts and craft = Probability they signed for swimming * Probability that they didn't sign for Arts and Crafts = 0.360*0.696 = 0.25056

Answer:
B
Step-by-step explanation:
1. Plot the points on a graph (reflected across x-axis)
Answer:
6 ounces of oil
Step-by-step explanation:
Well the first salad dressing is probably 8 ounces because 2+6 = 8
Then we must find out how large this recipe compares to the original
24/8 = 3
So we need all the ingredients to be tripled to keep the same ratio of 2:6
The new dressing has 2*3 ounces of oil and 6*3 ounces of vinegar
which equals 6 ounces of oil and 18 ounces of vinegar.
Hope this helps!
