Answer:
D.
Step-by-step explanation:
The difference in pizza delivered between driver A and driver B is 10 pizzas.
We can find this by doing 20-10 which is 10.
The MAD is 2.
D says that Driver A has less pizzas delivered than Driver B by 5 MADs. Since 1 MAD is 2, 5 MADs is 10.
Meaning D says that driver A delivered 10 less pizzas than Driver B, which is correct.
Hope this answer helped! :)
Answer:
a) P(X<50)=0.9827
b) P(X>47)=0.4321
c) P(-1.5<z<1.5)=0.8664
Step-by-step explanation:
We will calculate the probability based on a random sample of one moped out of the population, normally distributed with mean 46.7 and standard deviation 1.75.
a) This means we have to calculate P(x<50).
We will calculate the z-score and then calculate the probability accordign to the standard normal distribution:
b) We have to calculatee P(x>47).
We will calculate the z-score and then calculate the probability accordign to the standard normal distribution:
c) If the value differs 1.5 standard deviations from the mean value, we have a z-score of z=1.5
So the probability that maximum speed differs from the mean value by at most 1.5 standard deviations is P(-1.5<z<1.5):
A degree of a monomaniacal is the sum of the exponents of all its variables. So 8+5 would give u 13
Answer:
$7.15
Step-by-step explanation:
The best way to solve this is by crossing out the data you don't need so you're left looking at the key pieces to put the equation together. If his dad paid him $45.76 for 6.4 hours, then all you need to do is divide 45.76 by 6.4. (Hint: Use a calculator, it makes it ten times faster than trying to write it out!)
45.76 ÷ 6.4 = 7.15
So Greg made $7.15 an hour working with his dad.
