Answer:

  f(n) = 4 +n

Step-by-step explanation:

We assume you want a function that tells the total number of tiles in figure N.

There are 4 triangular tiles in each figure. The number of square tiles is equal to the figure number (n). So, the total number of tiles in figure n is ...

  f(n) = 4 +n

The graph of a quadratic function having the form f(x) = ax? + bx + c passes
insens350 [35]

Answer:

  f(-3) = -20

Step-by-step explanation:

We observe that the given x-values are 3 units apart, and that the x-value we're concerned with is also 3 units from the first of those given. So, a simple way to work this is to consider the sequence for x = 6, 3, 0, -3. The corresponding sequence of f(x) values is ...

  34, 10, -8, ?

The first differences of these numbers are ...

  10 -34 = -24

  -8 -10 = -18

And the second difference is ...

  -18 -(-24) = 6

For a quadratic function, second differences are constant. This means the next first-difference will be ...

  ? -(-8) = -18 +6

  ? = -12 -8 = -20

The value of the function at x=-3 is -20.

The attachment shows using a graphing calculator to do a quadratic regression on the given points. The graph can then be used to find the point of interest. There are algebraic ways to do this, too, but they are somewhat more complicated than the 5 addition/subtraction operations we needed to find the solution. (Had the required x-value been different, we might have chosen a different approach.)

a large study used records from canada's national health care system to compare the effectiveness of two ways to treat prostate
N76 [4]

Answer:

  • compile the list of the 300 prostate patients considering various diversities  i.e. various ages, various stages of the disease, various racial, social and economic background , various lifestyles as well.
  • divide the sample into two groups, ensuring that each group is diversified equally
  • Assign each group to the one of the two treatment procedures
  • follow up on the different group after treatment
  • compare the measurable variables from both groups after treatment in order to determine which treatment method is best

Step-by-step explanation:

A completely randomized design for this experiment can be carried out following the following steps
