Answer:
<h2>k = -1</h2>
Step-by-step explanation:
We have the point (5, k) and the equation 2x + y = 9.
Put the coordinates of the point ot the equation:
x = 5, y = k
2(5) + k = 9
10 + k = 9 <em>subtract 10 from both sides</em>
10 - 10 + k = 9 - 10
k = -1
The mean of the sample is 15.4 and the standard deviation of the sample is 2.87. This shows that the population parameters of the sample is lower and is less dispersed.
Answer:
38
Step-by-step explanation:
Answer:
It would be subtract the product of 2 and 4 from the product of 5 and 3, then add 5 because it’s parenthesis then you would multiply/devide then add/subtract whatever comes first
Step-by-step explanation:
5x3 - (2x4) + 5
5x3 - 8 + 5
15 - 8 + 5
7 + 5
12

The gradient/slopes of perpendicular lines are NEGATIVE reciprocal. This means that their product is -1.
