topjm [15]3 years ago

Step-by-step explanation:

To say "data vary" means the component opinions change from person to person. Particularly for certain people, certain parameters can change over time. Since the data vary, two separate statistical analyzes of the same variable can result in different outcomes. Thus statistical analyses should take into account this possible variability and thus we can never be 100% sure about the results of the statistical analysis.

Which statement describes the translation of y = −one half (x − 2)2 − 2 from standard position?
kaheart [24]
A quadratic in vertex form can be represented as

y = a(x-h)^{2} +k

a represents reflection over the x-axis, and a vertical stretch or compress 
- is reflection and a fraction (1/2) represents a compression.

-h represents a shift of that many units to the right (-2 shifts to the right  two units)

k represents a shift up or down (-2 is shifting down 2 units_

Reflected over the x-axis, Vertically compressed by a factor of 1/2, shifted 2 units to the right, and shifted 2 units down

Your averages and values are the following:
ioda

Answer: You need a grade of 78 on the final exam to earn a final grade average of at least 87 in each grading system.

Step-by-step explanation:

(85 + 90 + 95 + x)÷ 4 =87

Simplify:

(270 + x) ÷ 4 = 87

Rearrange:

(x + 270) ÷ 4 = 87

Multiply terms to Reduce:

4((x + 270) ÷ 4) = 4 * 87

Cancel Multiplied terms in Denominator:

x + 270 = 4 * 87

Multiply:

x + 270 = 348

Subtract 270 on both sides of the equation:

x + 270 - 270 = 348 - 270

Simplify:

x = 78
