It appears to be reflexive, since it's an angle congruent to itself.
Answer:
i can't see clearly
Step-by-step explanation:
So this is not too hard, as with any math problem we write what we know.
Starting speed: 80km/h
Time from P to Q: 2.5h
Increase in speed: 20km/h (25% is dividing by 4)
Distance from Q to R: 150 kilometers
So let's find the speed and distance for both legs of the trip.
Speed for P to Q: 80km/h
Distance from PtoQ: 200km (2.5h * 80km/h)
Speed from Q to R: 100km/h (80 +20)
Distance from QtoR: 150km.
Now we multiply the speeds by their respective distances add them and then divide by the total distance.
((80 *200) + (100 * 150))/350 = ~88.57143
Answer:
Construction of hypothesis
H₀ : p = 0.70
H₁ : p ≠ 0.70
Step-by-step explanation:
A the given statement does not give how much the goal was
lets suppose "getting rich" was an important personal goal than the proportion was 70 %
suppose that we believe that proportion has changed then construction of hypothesis for this H₀ for null hypothesis and H₁ is alternative hypothesis
Construction of hypothesis
H₀ : p = 0.70
H₁ : p ≠ 0.70
So construction of hypothesis state null and alternative hypothesis.
