Answer:c
Step-by-step explanation:
C. 5, 13,12, 67,23, right angle
Answer:
A
Step-by-step explanation:
The first answer is correct because we have a decay factor.
The sample is losing mass, so the number that is being multiplied by a power of x must be less than 1.
If the second answer were used, then the sample would be gaining mass.
We can first add up the cards so we know how many we have in all:
16 + 16 + 18 = 50 cards
We can do this a little bit easier if we get the "16"-cards in one number total.
16 + 16 = 32

= 32 x 2 =

50 x 2

= 64 : 2 = 32 %
100
We did just divide the % of two types cards on 2, so we get the %-chance of 1 type card.
I am not quite sure, but I think that 32 % is the correct answer.
Answer:
x = -3
Step-by-step explanation:
Take the 3x away from the right side.
-5x-3x=-8x
-8x = -24
Divide both sides by 8.
-8x/8 = x
-24/8 = -3
x = -3
