Answer:
Sharon bought a necklace with 90% blue beads.
Step-by-step explanation:
We are given that Sharon's necklace has 80 beads. We are also given that of those 80 beads, 72 of them are blue.
Therefore, we can set up a ratio of blue beads to total beads in order to find out the relationship.
Then, using the fraction we receive as a result, we can convert this to a decimal.
After we complete this calculation, we can multiply our decimal by 100 in order to obtain the relationship in percentage form.
Of the 80 beads, 90% were blue beads.
3/4 < 33/40 because 30/40 < 33/40
Answer:
0.9999
Step-by-step explanation:
Let X be the random variable that measures the time that a switch will survive.
If X has an exponential distribution with an average life β=44, then the probability that a switch will survive less than n years is given by
So, the probability that a switch fails in the first year is
Now we have 100 of these switches installed in different systems, and let Y be the random variable that measures the the probability that exactly k switches will fail in the first year.
Y can be modeled with a binomial distribution where the probability of “success” (failure of a switch) equals 0.0225 and
where
equals combinations of 100 taken k at a time.
The probability that at most 15 fail during the first year is
So, we know that
4/5n = 2/3
n = 2/3 x 5/4 . . . . .. if fraction is moved to other side of the equation the numerator and denominator will be swithced
n = 10/12 ......................... divide numerator and denominator by 2
n = 5/6
The answer is Fraction 5 over 6 hopes this help
Answer:
A. Height of the Flag pole
B. Longest.
Explanation:
Two similar triangles have corresponding sides with the same ratio.
A smaller triangle is showing the shadow of a person and the larger one is showing the shadow of a flag.
Now the person's shadow in the smaller triangle corresponding to the Height of the Flag pole.
The longest side of the large triangle corresponds with the Longest side of the smaller triangle.
