I believe that the cave is about -72 feet down under sea level.
Answer:
X : Z = 6 : 5
Step-by-step explanation:
X : Y = 3 : 1
Double both sides
X : Y = 6 : 2
Y : Z= 2 : 5
Combined
X : Y : Z = 6 : 2 : 5
Therefor
X : Z = 6 : 5
Answer: C=4
Step-by-step explanation:
5(5c-1)-1 = 23c + 6
1. Using PEMDAS. You know to do parenthesis first which is 5(5c-1)
Using distributive property you will get 25c-1-1 = 23c + 6
2. Simply on both sides and get 25c-2=23c+6
3. Using the rule that whatever you do on one side of the equal sign, you do on the other you can subtract 23c from both sides and get 2c-2=6. Then add 2 on both sides and get 2c=8
4. Divide both sides by 2 to get rid of the 2 and you get c=4
I think the answer is c 19
We will use Binomial Distribution in this case.
Since the coin is tossed 15 times. N which is the number of trails will be 15.
P = Probability of heads
Q = Probability of tails
X = No. heads occurring in each toss.
So, now we have to find the probability for exactly 10 heads.
P(x = 10) = C(15, 10) P^x Q^N-x
C(15, 10) (1/2)^10 (1/2)^5 = 0.0916
