Answer:
You may or may not need to include the units.
A = 18x - 18
P = 6x + 6
Graph is attached below. (2, 18)
Step-by-step explanation:
Substitute the information we need, "l" and "w", into the formulas.
l is for length, 6cm.
w is for width, (3x - 3)cm.
Use the formula for area of a rectangle.
A = lw
A = (6)(3x-3)cm²
A = (18x - 18)cm² or 18x - 18
Use the formula for perimeter of a rectangle.
P = 2(l + w)
P = 2(6 + (3x - 3))cm
P = 2(3x + 3)cm
P = (6x + 6)cm or 6x + 6
Linear equations are written in the form y = mx + b, so we do not need to factor or further simplify the formulas.
To graph, first turn the "m" value into a fraction form.
8 -> 8/1
6 -> 6/1
You need two points to graph each line.
For each equation, the first point is on the y-axis at the "b" value. Then use the "m" in the equation to count the number of units up (numerator) and to the right (denominator).
The solution is (2,18)
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
