A cooler has 12 apple juices and 15 grape juices. 9 of the apple juices are sugar free and 5 of the grape juices are sugar free.
Alexus [3.1K]

A - juice is not sugar free

B - juice is not grape juice


|\Omega|=27\\ |A|=13\\ |A\cap B|=3\\\\ P(A)=\dfrac{13}{27}\\ P(A\cap B)=\dfrac{3}{27}=\dfrac{1}{9}\\\\ P(B|A)=\dfrac{\dfrac{1}{9}}{\dfrac{13}{27}}=\dfrac{1}{9}\cdot\dfrac{27}{13}=\dfrac{3}{13}

So, it's D, assuming "3 13" meant \dfrac{3}{13}

Help me please it’s due today :/
jeyben [28]

Answer:

68 degrees

Step-by-step explanation:

This triangle is an isosceles triangle which means that two sides have equal lengths and when two sides have equal lengths that means that two angles are the same. so you add 56 and 56 together and you get a sum of 112. all triangles add up to a degree of 180, so you therefore subtract 112 from 180 which gives you an answer of 68 degrees , therefore x is 68

How do you solve x(x+h)=x-h for h?
WITCHER [35]

Answer: H = \frac{-x^{2}+x }{x+1}

Step-by-step explanation:

Step 1: Add h to both sides.

hx+x²+h=−h+x+h

hx+x²+h=x

Step 2: Add -x^2 to both sides.

hx+x²+h+−x²=x+−x²

hx+h=−x²+x

Step 3: Factor out variable h.

h(x+1)=−x²+x

Step 4: Divide both sides by x+1
