B is 2,2 A is -1,1 c is 2,-1
Answer:
6
Step-by-step explanation:
X(x+5)=234
x^2 +5x=234
x^2+5x-234=0
Factor:
x^2+5x-234
(x-13)(x+18)
the integers are 13 and 18.
The probability that both of them have the secret decoder ring will be 0.1305.
Inside the box of every cereal box contains a surprise gift.
The store manager assures employees that 22 of the 60 boxes on the shelf have a secret decoder ring.
And inside the other 38 boxes on the shelf contain a different gift.
If two cereal boxes are randomly selected from the shelf to purchase.
Then the probability that both of them have the secret decoder ring will be
The total events will be
Total event = ⁶⁰C₂
Total event = 1770
The favorable events will be
Favorable event = ²²C₂
Favorable event = 231
Then the probability will be
P = 231/1770
P = 0.1305
