Answer:
Step-by-step explanation:
10+n=15-10= 5 n=5
-10
X= 5y + 1
-2x + 9y = -1
-2(5y + 1) + 9y = -1
-10y - 2 + 9y = -1
-y - 2 = -1
-y = 1
y = -1
x + 5 = 1
x = -4
(-4, -1)
hey its -100 percent. the negative to show decrease.
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.
