(1, 1) and (4, -4)
Slope formula is : m = (y₂-y₁) / (x₂-x₁)
In this case :
x₁ = 1 ; x₂ = 4 ; y₁ = 1 ; y₂ = -4
Now that you know what variable counts as what, we simply just need to plug everything in.
m = (-4 - 1) / (4 - 1)
Simplify.
m = -5/3
Therefore, your slope is -5/3

Answer:
It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.
Step-by-step explanation:

1. Null and alternative hypothesis

2. Significance level

Freedom degrees is given by:

For a sgnificance level of 0,01 and 22 freedom degrees, t-student distribution value is:

3. Test statistic



In this case, we have an one left tailed analysis, it means that null hypothesis is rejected if 

Conclusion:
It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.
Answer:
20
Step-by-step explanation:
569/x=100/18
multiply both sides of the equation
569=5.55556
now we divide
569/5.55556
102.42=x
18% of 569=102.42
