• When you divide 185 by 5:
• 185 ÷ 5 = 37
• So, the answer is 37.

Explanation

If the correlation coefficient is 0, the two regression lines are perpendicular.

This is because a correlation coefficient of 0 indicates no linear relationship between the variables.

This causing the regression lines to be at right angles to each other.

Explanation

The word pentagon is derived from a Greek word, pente, meaning five sides or a five-sided polygon.

Explanation

To find the fraction equivalent to 2/5%, first convert the percentage to a decimal:

2/5% = (2/5) × (1/100) = 2/500 = 1/250

Explanation

= (x -3 + x + 3)/2

= (2x - 3 + 3)/2

=2x / 2

= x

Explanation

 The result of 50−15.5 is 34.5.

Explanation

We are given:

• H.C.F (Highest Common Factor) = 12

• Difference between the two numbers = 12

  Step-by-step method:

Let the two numbers be:
x and x + 12

Since H.C.F = 12, both numbers must be divisible by 12.

Let’s assume:

$$x=12a\text{and}x+12=12b$$

So,

$$x+12-x=12b-12a=12(b-a)=12\Rightarrow b-a=1$$

So:

$$a=k,b=k+1\Rightarrow \text{The numbers are }12k\text{ and }12(k+1)$$

Try k = 7:

$$12 × 7 = 84,quad 12 × 8 = 96 Rightarrow text{Numbers are } 84 text{ and } 96$$

• Difference: $96-84=12$ 

• H.C.F of 84 and 96 is 12 

Explanation

(4 x 3 + 5 x 6) / (18 x 2 – 22)

= (12 + 30) / (36 - 22)

= 42 / 14

= 3
