Answer: -3/2
Step-by-step explanation:
To find its distance away from 0, then just find its opposite.
On the number line if you graph 3/2, its opposite will be -3/2
4x^2 + x + 3 = 0
x = [-1 +/- sqrt (1^2 - 4 * 4 * 3)] / 8 = - 1 +/- sqrt ( --47) / 8
= ( - 1 +/- sqrt47i) / 8 = -0.125 + 0.857i , -0.125 - 0.857i
Answer:
y is 150
Step-by-step explanation:
a straight angle always measures 180 degrees. if x is 30, the simply minus 30 from 180. that should give u 150 which is your answer.
hope this helped!
Answer:
Option C) population
Step-by-step explanation:
We are given the following situation in the question:
A researcher is curious about the average IQ of registered voters in the state of FL.
Sample:
It is a part of a population. It is always smaller than the population.
Statistic:
Any numerical value or any other measure describing a sample of a population is known as statistic.
Population:
It is the universal data set. Every observation belongs to this group which is of interest. Sampling is done within population to obtain small groups of sample.
Parameter:
Any numerical value or any other measure describing the population is known as a parameter.
In this situation, the entire group of registered voters in FL is an example of a population because it contains all the individual for variable of interest.
Variable of interest:
Average IQ of registered voters in the state of FL.
Individual of interest:
Registered voters in the state of FL.
