Answer:
7
Step-by-step explanation:
Recall that a factor is a number that can divide a number and return a whole number as the quotient.
In this case, 91 / 7 = 13
So 7 is a factor
Answer:
Probability that one or more people in Arbalest got a cold is 0.9987.
Step-by-step explanation:
We are given that according to a report, 11 people got colds for every 2000 people.
There are 1200 people in the town of Arbalest.
The above situation can be represented through binomial distribution;

where, n = number of trials (samples) taken = 1200 people
r = number of success = one or more people got a cold
p = probability of success which in our question is probability
that people got colds, i.e; p =
= 0.55%
Let X = <u><em>Number of people in Arbalest who got a cold</em></u>
So, X ~ Binom(n = 1200 , p = 0.0055)
Now, Probability that one or more people in Arbalest got a cold is given by = P(X
1)
P(X
1) = 1 - P(X = 0)
=
=
= 0.9987 or 99.87%
Hence, the required probability is 99.87%.
Step-by-step explanation:
(x+4)(2x−5)(x−1)
----------------------c
(x+1)(x+4)(2x−5)
(x+4)^(1-1)(2x-5)^(1-1)(2x-5)^(1-1)
(x+4)°(2x−5)°(x−1)°
1×1×1
1
law of indices says that x²/x=x^(2-1)=x
180 - 143 = 37
180 - 37 - 61 = 82
The answer is 82°
