The equation to find percent error is:
percent error=(experimental-theoretical)/theoretical *100
So, (115-82.5)/82.5=0.393939*100
39.3939%, or 39.94%
Hope this helps!!
C is correct answer, passes through (5,-1) and also has slope of 3/4
Answer:
D
Step-by-step explanation:
10/7 = 1.4285
9/y = 1.4285
Multiply both sides by y.
9 = 1.4285y
Divide both sides by y.
6.3 = y
Answer:
y = 1/2x -1
Step-by-step explanation:
to find the y-intercept you find where the line crosses the y axis
for the slope you need to use the equation
change of y2 - change of y1
change of x2 - change of x1
Answer:
Adults: 75, girls: 100, Boys: 75
Step-by-step explanation:
2/5 x 250 = 100( girls)
3/10 x 250 = 75 (boys)
250 - (100 + 75) = 250 - 175 = 75 (Adults)
