Answer:
a. Quotient property of logarithms, P = log[(d + 1)/d]
b. log2 = 0.301
Step-by-step explanation:
a. State with property you would use to rewrite the expression as a single logarithm.
I would use the Quotient property of logarithms, which states that
logA - logB = log(A/B)
So, P = log(d+1) - log(d) = log[(d + 1)/d]
b. What is the probability that the number 1 is the leading digit
Since d = 1,
P = log[(d + 1)/d]
= log[(1 + 1)/1]
= log(2/1)
= log2
= 0.301
Answer:
379.56 ft
Step-by-step explanation:
25 squared = 625
diameter of the half circle is 25
Diameter divided by 2 is radius
pi r squared is the formula for area of circle
r=12.5
pi * 12.5 squared
Answer: Hence, she needed 42 yards of white yarn.
Step-by-step explanation:
Since we have given that
Ratio of blue yarn to white yarn is same
i.e. 1:1
Number of yards of blue yarn she used to make a scarf = 42 yards.
So, number of yards of white yarn she needed to a scarf would be
42 yards.
as there is ratio of 1:1.
Hence, she needed 42 yards of white yarn.
Answer:
True.
Step-by-step explanation:
We are given that two disjoint sets
We have to find that the statement number of outcomes of disjoint set is equal to sum of number of outcomes for each event
If sets are disjoint then
Let n(A)=x
n(B)=y
We know that
Hence, to find the number of outcomes of disjoints set ,add the number of outcomes for each event.
Therefore, the statement is true.
