Answer: The probability of pulling a Queen has a smaller chance of happening.
Step-by-step explanation: In a 52-card deck, you have 4 Queens altogether belonging to each of the four suits. If you pull a card at random out of a complete pack, the probability of picking a Queen would be as follows;
P(Q) = Number of required outcomes/Number of all possible outcomes
P(Q) = 4/52
P(Q) = 1/13
P(Q) = 0.07692 or 7.69%
Also in a 12-pair pack of socks, you have 3 pairs with the color grey. The probability of picking a pair of grey socks at random is given as follows;
P(G) = Number of required outcomes/Number of all possible outcomes
P(G) = 3/12
P(G) = 1/4
P(G) = 0.25 or 25%
Therefore the probability of pulling a Queen has a 7.69% chance of happening and thats a lower chance.
I got 2,500 left after 5 years.
10,000*15% = 1,500 or you could do 10,000*.15 = 1,500
That is a loss of 1,500 fish per year.
If you want to think of this as a proportion then you would do
Year/fish lost
1/1,500 = 5/x
X=5*1,500
X=7,500
The population of the fish after 5 years equals
10,000-7,500 = 2,500
So your answer is 2,500 fish are left
Answer:
21/4
Step-by-step explanation:
Rate of change also means slope.
Pick any two points, for example (8,167) and (12, 188)
Now use the formula y2-y1/x2 - x1 to find slope
188 - 167/ 12 - 8
21/4
The rate of change is 21/4, <em>note you would NOT convert the fraction into to a decimal until your teacher specifies you to.</em>
Answer: The concentration of the mixture is 0.5 p % .
Step-by-step explanation:
Given: 5 gallons of p% boric acid is mixed with 5 gallons of water.
Amount of boric acid = p% of 5 gallons
Total solution : 5 +5 = 10 gallons
then, the concentration of the mixture = 
Hence, the concentration of the mixture is 0.5 p % .
