6y + 7 I don't know if that's what you're looking for
Answer:
The answer to your question is 2 rational solutions.
Step-by-step explanation:
Equation
y = x² - 8x + 2
Solve using the general formula
x = [8 ± √(-8)² - 4(1)(2)] / 2(1)
Simplification
x = [8 ± √64 - 8] / 2
x = [8 ± √56] / 2
x = [8 ± 2√14]2
x₁ = 4 + √14 x₂ = 4 - √14
As √14 is positive, we conclude that the equation has two rational solutions.
Answer:
- <u><em>A. Both numbers are statistics.</em></u>
Explanation:
The number 94.6 is an average measure from a <em>sample</em>. It is the mean of a sample.
The number 65.3 is the standar deviation of a sample.
Then, thus numbers are used to estimate the values of the population.
The true mean and the standard deviation of a population are constant numbers; many times unknown (specially when the population is too big). As ,those values are <em>parameters</em> of the population, regardless they are known or not.
When, they are not known, the statistician must estimate them. The statistician does it using samples (one or more). Such <em>estimated values are not parameter but statistics.</em>
Statistics are values for a sample and may (in general will) vary from sample to sample, while the parameters, which belong to the population are fixed values.
Step-by-step explanation:
1. Draw the bottom line EF with a ruler.
2. Use a protractor and draw 2 long lines at 50 degrees, one from point E and one from F and make sure the two lines intersect.
