$421,369.20 , I just had this question on Apex.
Solution: The sum of probabilities of all the sample points must equal 1. And the probability of getting a head is equal to the probability of getting a tail. Therefore, the probability of each sample point (heads or tails) must be equal to 1/2. Let's repeat the experiment of Example 1, with a die instead of a coin.
Answer:
5
Step-by-step explanation:
Subtract 1 from both sides. The equation becomes 2.5d + 6.25 = 3.75d
Subtract 2.5d from both sides. The equation becomes 6.25 = 1.25d
Divide 1.25 from both sides. You get 5 = d
Answer:
y = 7/3 x + 2
Step-by-step explanation:
y = mx+b is the slope intercept form of a line
where m is the slope and b is the y intercept
Substituting in what we know
y = 7/3 x + 2
Answer:
The error is in step 3. You cannot use a property of logarithms to prove that same property.
Step-by-step explanation:
Here we the proof of the quotient rule as
If Logₐx = M and Logₐy = N
Then x =
and y = 
x ÷ y =
÷
= 
Take log of both sides we get
Logₐ(x÷y) = Logₐ
Logₐ(x÷y) =M-N logₐa
Logₐ(x÷y) =M-N
∴Logₐ(x÷y) = Logₐx - Logₐy
