If a number is divisible by 2 and 3 then it is divisible by 6

1 answer:

4 0

Yes it is it is because So for a number to be divisible by 6, it must also be divisible by 2 and 3. Therefore, we need to check if a number is even and then check if the sum of the digits is divisible by 3.

Answer:

Option B is correct.

the value of discriminant is, -7

Step-by-step explanation:

Given the equation: $x^2 + x +2 = 0$

To find the value of discriminant $b^2-4ac$

A quadratic equation is of the form $ax^2+bx+c = 0$ where a, b and c are coefficient of the equation.

On comparing with given equation we have;

a = 1 , b = 1 and c = 2

then;

Discriminant = $b^2-4ac =(1)^2 -4(1)(2) =1 -8 = -7$

Therefore, the value of discriminant is, -7

A cheerleading squad consists of ten cheerleaders of ten different heights. How many ways are there for the cheerleaders to line

Sindrei [870]

Answer:

11340

Step-by-step explanation:

We have 10 cheerleaders of ten different heights. There are two rows each having 5 positions so that five cheerleaders occupy the first row that have height less than the five cheerleaders who occupied the second row.

Therefore, Out of ten cheerleaders, two cheerleaders will be selected out of which the tallest one will occupy the position in the upper row and the second one will occupy in the lower row, therefore these two positions will be occupied in $10C_{2}$ ways. Now, we are left with 8 cheerleaders and following the same path, the next two positions will also be occupied in $8C_{2}$ ways, similarly, following the same path, the number of ways the cheerleaders will occupy the position will be: $10C_{2}$ × $8C_{2}$ × $6C_{2}$ × $4C_{2}$ × $2C_{2}$
