Here is the histogram of a data distribution. All class widths are 1. What is the median of this distribution?
Bingel [31]

Answer:

The median is 4.

Step-by-step explanation

if you layout all the number, you get

1,2,2,3,3,3,4,5,5,5,6,6,7

So, to find the median you find the number(s) right in the middle.

(Ex. 3,4,5; 4 is the median)

(Ex. 3,4,5,7; 4.5 is the answer)

The middle number of

1,2,2,3,3,3,4,5,5,5,6,6,7

is 4, so 4 is the median.

hope this helps. :)

Art wants to know how much he'll have to invest today to receive an annuity of $8,000 for three years if interest is earned at 1
Svet_ta [14]
He should invest $80,000 if he wants $8,000 at 10% interest. He can withdraw $8,000 at the end of each year. This is because if $8,000 is 10% of what he has in his bank account, to get the full amount (100%), we can multiply by 10, because 10% x 10= 100%. So $8,000 x 10= $80,000.

A transportation engineer uses the formula, R = 1600/15+127e, to determine the minimum radius of curvature (R) in meters, for a
Mashcka [7]

Answer:

The value is  e  =  1.92

Step-by-step explanation:

From the question we are told that

   The formula for radius of curvature is R = \frac{1600}{15} +127e

   The design speed of the roadway is  v =  40 \ km/hr

    The value of radius of curvature considered R =  350 m

From the equation given e is the superelevation rate

Now making the subject of the formula

        e  =  \frac{R}{127}  - \frac{1600}{1905}

At R= 350

         e  =  \frac{350 }{127}  - \frac{1600}{1905}

          e  =  1.92
