The length of each interval would be 3.75 rounding to whole number is 4.

Step-by-step explanation:

  • Stack in excel from lowest to highest points.
  • Total number of data points are 14.
  • Frequency distribution to be created.
  • You can use countif function for frequency distribution.
  • Since we have already got the number of intervals.
  • It will be easier to calculate the number if intervals.
  • normally there should be 5-15 intervals to get a better histogram.
  • Basic formula is Highest data point - Lowest data point/ classes/intervals.
  • So (29-14)/4 = 3.75 rounding to 4.

Do you guys know how to solve with equation?
AlexFokin [52]

Answer:

{-8, 3/4}

Step-by-step explanation:

One by one, set the factors equal to zero and solve for v:

8 + v = 0 yields v = -8, and

4v - 3 = 0 yields 4v = 3 and v = 3/4

Suppose a certain character in a role-playing game has an ability to use in battles. When activated, the ability deals damage to
Helen [10]

Answer:

The chance of getting exactly 3 hits is =  0.20

Step-by-step explanation:

P.S - The exact question is -

As given,

F(x) = 0 ,          x < 1

         0.30 ,     1  ≤ x < 2

         0.56 ,     2 ≤ x < 3

         0.76 ,     3 ≤ x < 4

         0.9 ,       4  ≤ x < 5

         1 ,            5  ≤ x

Now,

f(x) = 0.30 ,                            x = 1

        0.56 - 0.30 = 0.26 ,     x = 2

         0.76 - 0.56 = 0.20 ,     x=3

         0.9 - 0.76 = 0.14  ,       x = 4

         1 - 0.9 = 0.1 ,                 x = 5

          0,                                 otherwise

Now,

The chance of getting exactly 3 hits is = f(x = 3) = 0.20
