M=2*2*3*5*5 and N=2*2*2*3*3*7 find the largest number that divides exactly M and N

Gelneren [198K]

Answer:

6

Step-by-step explanation:

M=2*2*3*5*5=300

N=2*2*2*3*3*7=504

Common factors between the two numbers are 2 and 3

The GCF(greatest common factor):

2×3 = 6

To see if it is true:

300/6 = 50

504/6 = 84

6 is the answer to the question.

The ages of students at a university are normally distributed with a mean of 21. What percentage of the student body is at least

stich3 [128]

Answer:

50%

Step-by-step explanation:

Recall : When given a normal or Symmetric distribution, the mean of the distribution is at the centre with 0.5 or 50% of the distribution to either side (right and left) of the distribution.

Hence, if the mean = 21 ; then the percentage of student body with atleast 21 years is the percentage to the left of the distribution, which is 50%.

Therefore, P(x ≤ 21) = 0.5 = 50%

Len [333]

There are a total of 30 students in the class. The equation used to solve the question is, $\frac{8}{10}$ × x = 24.

Step-by-step explanation:

Step 1; It is given that 24 students make up eight-tenths of the entire class. Assume the total number of students in class is x. So we have 24 will equal eight-tenths of x, as x is the total number of students.

The equation is $\frac{8}{10}$ × x = 24. Multiply both sides by $\frac{10}{8}$

$\frac{8}{10}$ × x × $\frac{10}{8}$ = 24 × $\frac{10}{8}$ , The $\frac{8}{10}$ and $\frac{10}{8}$ cancel out each other on the LHS.

x = $\frac{240}{8}$ = 30.

So there are 30 students in the class in total i.e. x = 30.

Step 2; To draw the bar chart, measure the entire length of the bar and divide it by 10. Shade eight-tenths of the bar and name it students that are going to the trip = 24, the remaining two-tenths is named students not going = 6.
