Sampling every 100th invoice would be an example of:_______a. Randomization.b. Proxemics.c. Stratification.d. JRP.e. Observation
gregori [183]

Answer: C. Stratification

Step-by-step explanation: There are diverse samping techniques employed for statistical purposes depending on the tipe and nature of data available or other factors. When a data population is sampled in sects such that the entire data is divided into a equals groups at a fixed intervals based on a certain criteria, it is called stratified sampling. Here, data is divided into strata, with each stratum containing a fixed amount of samples with each partition taking place at regular interval. In the scenario stratification process is employed by sampling at a fixed and regular interval, however, the random nature of the data is not violated.

This was an exceptionally dry year for portions of the southwestern United States. Monthly precipitation in Phoenix, Arizona, wa
Otrada [13]

Using the vertex of a quadratic function, it is found that Phoenix received the highest amount of precipitation on the month of May.

<h3>What is the vertex of a quadratic equation?</h3>

A quadratic equation is modeled by:

y = ax^2 + bx + c

The vertex is given by:

(x_v, y_v)

In which:

x_v = -\frac{b}{2a}

y_v = -\frac{b^2 - 4ac}{4a}

Considering the coefficient a, we have that:

  • If a < 0, the vertex is a maximum point.
  • If a > 0, the vertex is a minimum point.

In this problem, the precipitation each month x in Phoenix is given by:

y = -0.04088x^2 + 0.4485x + 1.862

Hence the coefficients are a = -0.04088, b = 0.4485, c = 1.862, and the month for which the precipitation will be highest is given by:

x_v = -\frac{0.4485}{2(-0.04088)} = 5.48

Hence during the month of May.

Which transformations are nonrigid transformations? Check all that apply. dilation reflection rotation stretch translation
AysviL [449]

Answer: Dilation and stretch

Step-by-step explanation:

  • Rigid transformations that are also called as isometry are the transformations which preserves the side lengths and the angle measures of a polygon. It does not affect the size of the shape. The shape doesn't shrink or get enlarger.

There are four rigid transformations: <em>reflections, rotations, translations and glide reflection.</em>

  • Dilation and stretch are non rigid transformation because they change the size of the figure. They produces similar figures.
