Answer:
This is already in slope-intercept form.
Step-by-step explanation:
slope= -4 and y intercept is 0,3
Rise over run to find the slope so 4/2 which = 2
Answer:
H0: p(1980) = p(2010) ; H1 : P(1980) > P(2010)
0.02
Step-by-step explanation:
Given that:
Sample size in both 1980 and 2010 = 1000 samples :
Proportion in favor :
P(1980) = 0.66
P(2010) = 0.64
To test the hypothesis :
Null hypothesis :
Proportion in favor are the same in both years
Null hypothesis = H0 = p(1980) = p(2010)
Alternative hypothesis :
Proportion in favor in 1980 is greater than that in 2010
Alternative hypothesis = H1 : P(1980) > P(2010)
The sample statistic :
P(1980) - p(2010)
0.66 - 0.64
= 0.02
12x14 is 168 12x2=24 14x2=28 24x28=672
672/168=4 The area is affected by a scale factor of four. Because the label of area is the unit squared, you just square the number that the dimensions are being multiplied by.
