Solve the system of equations.<br><br> y=3x<br> y=x^2-10
puteri [66]

Answer:

y=3x.........1

y=x^2-10.......2

substituting value of eq 1 to 2

3x=x^2-10

x^2-10-3x=0

x^2-3x-10=0

x^2-5x+2x-10=0

X(x-5)+2(x-5)=0

(x-5)(X+2)=0

then

X=5 or X=-2

again

y=??

when X=5

y=3×5=15

when X=-2

The probability of picking a card with an even number is \frac{3}{10}.

<h3>What is probability?</h3>
  • Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true.
  • The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.

To find the probability of picking a card with an even number:

  • There are 10 cards on which numbers are written 7, 11, 12, 13, 14, 18, 21, 23, 27, and 29.
  • These cards are placed on a table with the numbers facing down.
  • To find the probability of picking a card with an even number, first, we count all the even numbers written on the cards.
  • 12, 14, and 18 out of 10 cards there are 3 even numbers written on the cards.
  • So, the probability of picking a card with an even number is \frac{3}{10}.

Therefore, the probability of picking a card with an even number is \frac{3}{10}.
