For the year 2010, 33% of taxpayers with adjusted gross incomes between $30,000 and $60,000 itemized deductions on their federal

income tax return. The mean amount of deductions for this population of taxpayers was $16,642. Assume that the standard deviation is σ = $2,440. If required, round your answer to two decimal places.
(a) What are the sampling distributions of x for itemized deductions for this population of taxpayers for each of the following sample sizes: 30, 50, 100, and 400?
(b) What is the advantage of a larger sample size when attempting to estimate the population mean?

If angle "a" measures 42° the the other angles that will be congruent to angle "a" and also measure 42° will be angle d, angle e and angle h .

In the question ,

a figure is given ,

From the figure we can see that 2 parallel lines are cut by a transversal .

So ,

angle a = angle d   .......because vertically opposite angles .

angle a = angle e   ...because corresponding angles are equal in measure

also

angle e = angle h      .... because vertically opposite angles .

Therefore , If angle "a" measures 42° the the other angles that will be congruent to angle "a" and also measure 42° will be angle d, angle e and angle h , the correct option is (a) .

If all 3 drones have the same mass which one has the thr greatest acceleration?​
Komok [63]

Answer:

We conclude that the red drown has the greater the acceleration.

Step-by-step explanation:

Given

Given that all 3 drones have the same mass.

To determine:

Which drone has the greatest acceleration

From the figure, it is clear that the red drown has a steeper slope. We know that the steeper the slope of the line the greater the acceleration.

It is also visible the red drone has already covered 50 km in just 50 minutes speed, while the blue drone covered around 30 km in 50 minutes and the green drone is the slowest of all, covering less than 20 km in 50 minutes.

Therefore, we conclude that the red drown has the greater the acceleration.
