Write the equation for the function graphed below.
1 answer:
The equation of a line passing through (0, 0) and (2, 10) is y = 5x
<h3>Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope of the line) and b is the y intercept.
Let us assume that the graph is a straight line passing through (0, 0) and (2, 10), hence:
The equation of a line passing through (0, 0) and (2, 10) is y = 5x

The length of the third side of the triangle will be 4 centimeters if it is a right-angled triangle.
<h3>What is a triangle?</h3>A triangle is a geometric shape having three sides and the area is equal to 270 degrees. A right angle triangle is one where the angle of one side is exactly 90 degrees.
If two sides measure 3 and 5 centimeters, the triangle will have a right angle if the third side measures around 4 centimeters.
Hence, the third side of the triangle will be 4 centimeters.

Answer:
The size of the sample needed = 67.65
Explanation:
Given that :
The margin of error = 10% = 0.10
The confidence level = 90% = 0.90
Level of significance = 1 - 0.90 = 0.10
At ∝ = 0.10
Since the proportion of people that supported him/her is not given, we assumed p = 0.50
The margin of error formula can be expressed as:
Squaring both sides; we have:
n = 67.65
Therefore, the required sample size = 67.65
