if one card is drawn from a standard 52 card playing deck, determine the probability of getting a ten, a king or a diamond.

IceJOKER [234]

To find the answer:

The probability of getting a ten:

=4/52

The probability of getting a king:

=4/52

The probability of getting a diamond:

=52×1/4
=13/52

However,there would be king and ten of diamond which overlapped and therefore -2/52 would be in the equation.

We can then sum up to find the equation:

=4/52+4/52+13/52-2/52
=21/52-2/52
=19/52

Therefore the answer is 19/52.

Hope it helps!

Total cost for Diego to attend university,

$11,850 + $10,645 + $1,780 + $1,864 + 1,602

$22,495 + $5,246
$27,741

Now for 4 years, we have to multiply it by 4.

$27,741 × 4

The function f(x) = –x2 + 20x – 75 models the profit from one customer, in dollars, a shop makes for printing photos, where x is

trasher [3.6K]

The function is graphed as shown below

Part A:

We use the formula $- \frac{b}{2a}$ to find the vertex of the function. A quadratic function of the form of $a x^{2} +bx+c$ and equating this form to the given function $- x^{2} +20x-75$ , we have
$b=20$ and $a=-1$ .

Substituting $a$ and $b$ into the vertex formula, we have
$x=- \frac{20}{2(-1)}=10$ , as shown in the graph

This calculation means that the highest profit is achieved when the number of photo printed equals to ten photos

Part B:

We can find solution to this equation by factorising

$- x^{2} +20x-75=0$
$-( x^{2} -20x+75)=0$
$x^{2} -20x+75=0$
$(x-5)(x-15)=0$
$x=5$ and $x=15$ , as shown in the graph

The two values means that the company makes no profit when they either produce 5 or 15 photos
