What is the LCM of 12,30 and 42

Hoochie [10]

Answer:

420

Step-by-step explanation:

We can find the prime factors of each of the numbers first before finding their LCM.

12: 2 × 2 × 3

30: 2 × 3 × 5

42: 2 × 3 × 7

To find the LCM, we need to see if they are any common prime factors between all three numbers. The common prime factors are 2 and 3. Then, we multiply 2 and 3 with the remaining outstanding factors, which are 2, 5, and 7.

LCM: 2 × 2 × 3 × 5 × 7 = 420

Assume that adults have IQ scores that are normally distributed with a mean of 100 and a standard deviation of 20. Find the prob

Ipatiy [6.2K]

Answer:

Randomly selected adult has an IQ less than 136 is 0.9641

Step-by-step explanation:

It is given that, it is normal distribution with mean 100 and SD as 20.

So, let's use the formula of z-score

z= $\frac{x-mean}{SD}$

For this problem,

x= 136

Plug in this value into the formula

z-score= $\frac{136-100}{20}$

=1.8

Now, use z-score table to find the probability

Find the corresponding value for the row 1.8 and the column 0.00, we do get 0.9641

So, Randomly selected adult has an IQ less than 136 is 0.9641
