Answer: -1 1/7

Explanation: Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes. This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 24 and 21 using 24÷321÷3=8/7. The fraction is the same as 8÷7. Therefore: 3/7÷3/8=1 1/7

If the probability of a win is 0.02, and the probability of a draw is 0.8, what is the probability of a loss?
atroni [7]
A probability is a number between zero and one. 

There are 3 options win, lose or draw. 
This means that (win + loss + draw = 1)

From the information given you know:
Win = 0.02
Draw = 0.8 

So: 0.02 + loss + 0.8 = 1 
Therefor loss = 1 - 0.8 - 0.02 
loss = 0.18 
final answer ^

Work out the equation of the line which has a gradient of 2 and passes through the point (1, 4)
leva [86]

Answer:

y = 2x + 2

Step-by-step explanation:

The slope is also called the gradient of the line.

The slope that is given is two, and the point is (1, 4).

I made a point slope equation, and then converted it into a slope-intercept equation.

y-4=2(x-1)\\\\y-4=2x-2\\\\y-4+4=2x-2+4\\\\\boxed{y=2x+2}

Hope this helps.
