X= r-h/y<br> solve for h and r

malfutka [58]

X = r - h/y ; Solve for h & r

Let's first solve for h :)

Add h/y to both sides.

h/y + x = r

So, r = h/y + x

Now, let's solve for h.

x = r-h/y

Subtract r from both sides.

-r + x = -h/y

Multiply both sides by y.

y(-r + x) = y(-h/y)

Simplify.

-ry + xy = -h

Divide both sides by -1.

ry - xy = h

So, h = ry - xy

~Hope I helped!~

A new surgical procedure is said to be successful 60% of the time. Suppose the operation is performed five times and the results

USPshnik [31]

Answer:

0.07776, 0.3456,0.08704

Step-by-step explanation:

Given that a new surgical procedure is said to be successful 60% of the time

Let X be the no of successes

Then X has only two outcomes and each trial is independent of the other

Hence X is binomial with p = prob of success in a single trial = 0.60

n = Number of operations performed = 5

Prob that

a) all five operations are successful =

$P(X=5)\\= (0.6)^5\\=0.07776$

(b) exactly three are successful

= $P(X=3) = 5C3 (0.6)^3(0.4)^2\\= 0.3456$

(c) less than two are successful

$==P(X$
