A=(1/2)h(b1+b2) solve for h
pshichka [43]

Answer:

\large\boxed{h=\dfrac{2A}{b_1+b_2}}

Step-by-step explanation:

A=\dfrac{1}{2}h(b_1+b_2)\qquad\text{multiply both sides by 2}\\\\2A=2\!\!\!\!\diagup\cdot\dfrac{1}{2\!\!\!\!\diagup}h(b_1+b_2)\\\\2A=h(b_1+b_2)\qquad\text{divide both sides by}\ (b_1+b_2)\\\\\dfrac{2A}{(b_1+b_2)}=\dfrac{h(b_1+b_2)}{(b_1+b_2)}\qquad\text{cancel}\ (b_1+b_2)\\\\\dfrac{2A}{b_1+b_2}=h\to h=\dfrac{2A}{b_1+b_2}

Use the probability distribution graph to answer the question. P(X≤a)=0.6 What is the value of a?
Stella [2.4K]
Answer: If P(x<a) = 0.6, then the value of a will be 0.25.

In this type of problem, it is safe to assume the normal distribution unless you are told something different. 

In this probability, we have to find the z-score for a that gives a probability of 0.6. You will need a normal distribution chart to do this problem. Just find the probability that is closest to 0.6 and use that z-score.
