There is 2 ways to do this...decimal to percent
(1) multiply by 100..... 0.7 x 100 = 70%
(2) move the decimal 2 spaces to the right = 70%
Many statements can be true about those parabolas, so you need to include the list of choices.
This is the list of answer choices that I found for this same question:
<span>A. The second parabola opens downward.
B. The second parabola opens upward.
C. The points of intersection are on the x-axis.
D. The points of intersection are of equal distance from the y-axis.
While A, B or C may be or may not be true, D has to be true.
D. has to be true because the symetry axis of both parabolas is x = 0, so the intersection points will be necesarily to the same distance of the x-axis and the y-axis.
Answer: </span>
<span>The points of intersection are of equal distance from the y-axis.

Answer:
The given statement describe inferential statistics.
Step-by-step explanation:
Descriptive Statistic:
- It helps us to summarize a given data set.
- It could describe the entire population or a sample from the population.
- There are two types of descriptive measures: measures of central tendency and measures of variability
- Central Tendency: Mean, mode, Median
- Measure of Viability: Standard Deviation, Variance, Range, Interquartile range
Inferential Statistic:
- It s the process of estimating population parameter with the help of a sample from the population.
- A random sample from the population is used to describe the population with the help of sample statistic.
Given Scenario:
"Based on a sample of 170 truck drivers, there is evidence to indicate that, on average, independent truck drivers earn more than company-hired truck drivers."
Thus, this is an example of a inferential statistics as a sample was used to estimate the population.
Here,
Sample:
Sample of 170 truck drivers
Population:
All truck drivers.
With the help of a sample, we approximated the population, thus, this statement describe inferential statistics.
To find the factor a a polynomial from its roots, we are going to seat each one of the roots equal to
, and then we are going to factor backwards.
We know for our problem that one of the roots of our polynomial is -3, so lets set -3 equal to
and factor backwards:
is a factor of our polynomial.
We also know that another root of our polynomial is
, so lets set
equal to
and factor backwards:
(
is a factor of our polynomial.
We can conclude that there is no correct answer in your given choices.
