Write 5% as a decimal.

1 answer:

3 0

You cannot do it that way. Make sure the question you wrote is correct, because you would divide 5 by 100, not 100 by 5. A simple way is to move the decimal point two points to the left. 5% as a decimal is 0.05.

The answer is false if the question is written this way.

Express the probability that a die will land on a number less than 5 as a fraction

ziro4ka [17]

ANSWER

$P(E)=\frac {2} {3}$

EXPLANATION

When a die is tossed, the possible outcomes are

S={1,2,3,4,5,6}.

$n(S)=6$

The event of getting a number less than 5 is

E={1,2,3,4}

$n(E) = 4$

$P(E)=\frac{n(E)} {n(S)}$

$P(E)=\frac {4} {6}$

$P(E)=\frac {2} {3}$

Find the two numbers whose sum is 24 and whose product is as large as possible.

svetlana [45]

Let, the numbers are: x, (24-x)
Let, P(x) denote their products. Then, we have:
P(x) = x(24-x) = 24x - x²
P'(x) = 24-2x
P''(x) = -2

Now, P'(x) = 0 ⇒ x = 12
Also,
P''(12) = -2 < 0

So, By second derivative test, x = 12 is the point of local maxima of p. Hence the product of the numbers is the maximum when the numbers are 12 and (24-12) = 12

So, In short that numbers would be 12,12

Hope this helps!
