A person is watching a boat from the top of a lighthouse. The boat is approaching
Lapatulllka [165]

9514 1404 393

Answer:

  445.10 feet

Step-by-step explanation:

The relation between angle of depression and distance to the boat is ...

  Tan = Opposite/Adjacent

  tan(angle of depression) = (200 ft)/(distance to boat)

Then the distance to the boat is ...

  distance to boat = (200 ft)/tan(angle of depression)

__

We want the change in distance between the two angles, so ...

  change in distance = (200 ft)/tan(17°31') -(200 ft)/tan(46°41')

  = (200 ft)(cot(17°31') -cot(46°41'))

  change in distance ≈ 445.10 ft

Lindsey found the median and mean of the list of numbers below: 4, 6, 8, 8, 15 If the number 23 was added to the list, then ____
Sav [38]
D.) The mean will increase

The mean is all the numbers added together than divided by the amount of numbers there, so if you do this: 4 + 6 = 10 + 16 = 26 + 15 = 41/5 = 8.2

4 + 6 = 10 + 16 = 26 + 15 = 41 + 23 = 64/6 = 10.66666666666

As you can see it increased! Hope this helped! Pls give brainiest if you can

Suppose that you are about to purchase a car and have narrowed your choices to two models --Model A and Model B. All things are
Ymorist [56]

Answer:

A. Model B with the smaller standard deviation is preferable, because the smaller value implies that the mean is a more reliable representation of maintenance costs.

Step-by-step explanation:

The standard deviation is a measure of the variability of a dataset about a mean value. Larger values of standard deviation implies that the values varies Hugely about the mean whole smaller variability measure values mean that the data only varies a little about the mean. The implication of having a large variability value is that, low and high values in the data can be very different from the mean values, hence, lowering the reliability of Mean value. The lesser varibality gives the mean more reliability as a measure of centre
