Answer:
x = 7 (multiplicity 2)
Step-by-step explanation:
When the function is written in factored form, the zeros are the values of the variable that make the factors zero.
y = (x -7)(x -7)
The values x = 7 and x = 7 will make the factors zero. The zero is said to be x=7 with multiplicity 2.
__
On the graph, the zeros are the x-intercepts (where y=0). The graph only touches the x-axis, but does not cross. With some experience, you can recognize that this is a zero with even multiplicity (2).
Answer:
$1269.23
Step-by-step explanation:
Since Sarah is paid biweekly (every 2 weeks), and there are 52 weeks in a year...
÷
Sarah is being paid 26 weeks out of the year.
Divide 33,000 by 26 (I only list 4 places after the decimal):
÷
Round 1269.2307 to the nearest cent (hundredth):
Answer:
a
Yes it involves a statistical test
The population parameter(s) of interest is
The sample size is n = 100
The average reaction time of the right hands for the right-handed participants
The average reaction time of the left hands for the left-handed participants
The null hypothesis is ,
The alternative hypothesis is
b
Yes it involves a statistical test
The population parameter(s) of interest is
The sample size is n = 100
The average reaction time of the right hands for the right-handed participants
The average reaction time of the left hands for the left-handed participants
The null hypothesis is ,
The alternative hypothesis is
c
Yes it involves a statistical test
The population parameter(s) of interest is
The percentage of people in the community living in a mobile home is denoted with p
The sample size is n = 1000
The null hypothesis is ,
The alternative hypothesis is
Step-by-step explanation:
Considering the first statement
Testing 100 right-handed participants on the reaction time of their left and right hands to determine if there is evidence for the claim that the right hand reacts faster than the left.
Yes, the analysis does involve a statistical test.
The null hypothesis is ,
The alternative hypothesis is
Here is the average reaction time of the right hands for the right-handed participants
and is the average reaction time of the left hands for the left-handed participants
Considering third statement
Polling 1000 people in a large community to determine if there is evidence for the claim that the percentage of people in the community living in a mobile home is greater then 10%.
The percentage of people in the community living in a mobile home is denoted with p
The sample size is n = 1000
The null hypothesis is ,
The alternative hypothesis is
The line cuts the X axis at and is parallel to the Y axis.
Thus the equation of the line is $\boxed{x=3}$
