Forty tickets are sold for a raffle with two prizes. You buy two tickets. What is the probability that you will win both prizes

1 answer:

5 0

When you first pick a ticket, there are 2 winning tickets and 40 total tickets. This means that there is a 2/40 chance of your ticket being a winning one. This fraction can be reduced to 1/20.

After this, there will be 1 winning ticket left and 39 total tickets. There is a 1/39 chance of the next ticket being a winning one. We multiply these two fractions together to get our answer. 1/20 * 1/39 = 1/780, so there is a 1/780 chance of having 2 winning tickets.

Find the value of the expression 3m^2+2p^2-15 when m =3 and p = 10

mylen [45]

$3m {}^{2} + {2p}^{2} - 15$
m = 3
p = 10

$3 \times 3 {}^{2} + 2 \times {10}^{2} - 15 =$
$3 \times 9 + 2 \times 100 - 15 =$
$27 + 200 - 15 =$
$212$

Hence, the answer is 212.

Y = 2x -7<br> x + 2y = 1

Olenka [21]

Easy
y=2x-7
sub 2x-7 for every y you se inother equation
x+2(2x-7)=1
x+4x-14=1
5x-14=1
add 14 both sides
5x=15
divide 5
x=3

sub back

y=2x-7
y=2(3)-7
y=6-7
y=-1

(3,-1) is solution
