1. Factor out the greatest common factor (GCF). (There will not always be one). 2. Count the number of terms.
3. Check to be sure each factor is prime, if not, repeat 1-3.
4. Check by multiplying the factors out to see if you get the original polynomial.

The LCM of two numbers is 48. The number one in the ratio 2:3. Then Sum of the numbers is:

Oksi-84 [34.3K]

Answer:

Step-by-step explanation:

Let the numbers be 2x and 3x

Then their L.C.M. = 6x

BUT also their LCM=48

6x=48

x=48/6

x=8

So,

First number=2x=2x8=16

Second number=3x=3x8=24

The numbers are 16 and 24.

Hence required sum =(16+24)=40

So none of the options are correct

A biased coin has a probability of 0.4 of coming up heads. What is the probability that when flipped one hundred times it comes

inn [45]

Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271

Using the binomial probability relation :

P(x = x) = nCx * p^x * q^(n-x)
p = probability of success = 0.4
q = 1 - p = 0.6
n = number of trials = 100

P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)

Using a binomial probability calculator :

P(x ≥ 100) = 0.0271

Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271
