<u><em>Answer:</em></u>
The slope of the line that passes through (-1, -7) and (3, 5) is 3
<u><em>Explanation:</em></u>
<u>The slope of the line is calculated using the following rule:</u>

<u>We are given the following points:</u>
(3 , 5) representing (x₁ , y₁)
(-1 , -7) representing (x₂ , y₂)
To get the slope, we will simply substitute with the givens in the above equation
<u>This is done as follows:</u>

You haven't attached the table for the second part. However, follow the same procedure. Pick two points from the table, substitute with them in the above equation and you'll get the slope

Answer:
you<u> accept </u>the alternative hypothesis
Step-by-step explanation:
The null and alternative hypothesis can be computed as follows:

The sample proportion 


The test statistics can be computed as:


Z = -2.5
The P-value = 2( Z< -2.5)
From the tables;
The P-value = 2 (0.0062)
The P-value = 0.0124
The significance level = 0.01
Since the P-value is > significance level; we fail to reject the null hypothesis.
Conclusion: we accept the alternative hypothesis
Answer:
1282kg
Step-by-step explanation:
1.0*1.12*1.1=1.232 tonnes
50kg + 1232kg = 1282kg

Answer:
see attached
Step-by-step explanation:
The vector difference u -v can be represented on a vector diagram by the sum u +(-v), where -v is a vector the same length as v, but in the opposite direction.
