Answer:
See below
Step-by-step explanation:
Given there are 56 M&M's:
- Expected Value of Blue = 56(0.24) = 13.44
- Expected Value of Brown = 56(0.14) = 7.84
- Expected Value of Green = 56(0.16) = 8.96
- Expected Value of Orange = 56(0.20) = 11.20
- Expected Value of Red = 56(0.13) = 7.28
- Expected Value of Yellow = 56(0.14) = 7.84
Remember to use
to calculate expected value! This will especially be helpful if you are conducting a chi-squared test of independence.
Answer:
x = 816 kilometers per hour.
Step-by-step explanation:
Given the following data;
Distance traveled by Kirk = 450km
Distance traveled by Thor = 408 km
Let the average driving speed of Thor be x.
Translating the word problem into an algebraic equation;
k = x + 6
We know that the time taken to cover a distance by an object with speed is given by the formula;
Time = distance/speed
Substituting into the equation, we have;
408/x = 405/x + 6
Cross-multiplying, we have;
408*(x + 6) = 405*x
408x + 2448 = 405x
408x - 405x = 2448
3x = 2448
x = 2448/3
x = 816 kilometers per hour.
We can say that lines A and D are <em>perpendicular</em>.
