The answer would be y=-13x+7
hope this helps ;]
Answer:
25
Step-by-step explanation:
remember that the pythagorean theorem is a²+b²=c²
so this equation would be:
7²+24²=c²
solve the exponents
49 + 576 = c²
combine like terms
625 = c²
take the radical of each number
√625 = √c²
25 = c

To solve this, we use the z test.
The formula:
z = (x – u) / s
where x is sample value = 20, u is the mean = 15, and s is
the standard deviation = 2.5
z = (20 – 15) / 2.5
z = 2
Since we are looking for values greater than 20, this is
right tailed test. We use the standard distribution tables to find for P.
P = 0.0228
Therefore:
number of students = 100 * 0.0228 = 2.28
<span>2 to 3 students will get greater than 20 measurement</span>
=(140+4) / 8
=(144/8) + (4/8)
=18 + 2
=<span>20</span>
We know that the graph of a function is a line that passes through the coordinates (2, 11) and (8, 14) and we must find the equation for the line.
1. We must use the next formula to find the slope
Where (x1, y1) and (x2, y2) are the points.
Now, replacing the points in the formula for the slope
2. We must replace the slope and one of the points in the next formula
Now, replacing the slope and the point (2, 11)
3. We must delete the parenthesis and solve the equation for y
