Answer:
23% error since 70 more people attended then Marcus counted
Step-by-step explanation:
To calculate the percent error:
- We find the difference between the predicted and the actual.
- We divide the absolute value of the difference by the actual recorded value.
- Convert to a percent by multiplying by 100 and adding a % sign.
Marcus counted 230 and 300 actually came.
1. 230-300=-70 but the absolute value is 70
2. 70/300=0.23
3. 0.23(100)=23%
Marcus' estimated had a 23% error.
The point-slope form:
We have the points (-1, 6) and (3, -2). Substitute:
<h3>Answer:</h3><h3>y - 6 = -2(x + 1) <em>point-slope form</em></h3><h3>y = -2x + 4 <em>slope-intercept form</em></h3><h3>2x + y = 4 <em>standard form</em></h3>
Answer:
Well, we have 4 cubes on one side and 3 triangles on the other.
The relationship would be 4:3
