Hi there!

To solve, we'll set up a proportion looking like this to find the percentage: 4/50 = x/100. Then, we'll cross-multiply: 50x = 400. Lastly, we'll divide both sides by 50 to find the percentage: x = 8%.

Hope this helps!! :)

Your friend rolls a number cube 500 times, how many times do you think an odd number will be rolled?

250, and this is because of probability. Since half of the numbers are odd numbers, and half are even. It would be hard to determine, your probability would be 1/2. 1/2 of 500 is going to be 250.

Complete the equation of the line through ( 4 , -8 ) and ( 8 , 5 )

Answer:

Therefore the equation of the line through ( 4 , -8 ) and ( 8 , 5 ) is

13x - 4y = 84.

Step-by-step explanation:

Given:

Let,

point A( x₁ , y₁) ≡ ( 4 ,-8)

point B( x₂ , y₂) ≡ (8 , 5)

To Find:

Equation of Line AB =?

Solution:

Equation of a line passing through Two points A( x₁ , y₁) and B( x₂ , y₂)is given by the formula

$(y - y_{1} )=(\frac{y_{2}-y_{1} }{x_{2}-x_{1} })\times(x-x_{1}) \\$

Substituting the given values in a above equation we get

$(y-(-8))=(\frac{5-(8)}{8-4})\times (x-4)\\ \\(y+8)=\frac{13}{4}(x-4)\\\\4(y+8)=13(x-4)\\4y+32=13x-52\\13x-4y=84...............\textrm{which is the required equation of the line AB}$
