Answer:
Neither.
Step-by-step explanation:
The slope for the first one is 1/4 and the slope for the second one is 4. These are reciprocals, but not opposite reciprocals, meaning they are not perpendicular. An opposite reciprocal means the fraction is flipped (ex. 3/1 to 1/3) and the sign is changed. The line parallel to y=1/4x would be y= -4x.
I'm pretty sure your answer would be $<span>28.51305 and that rounded would be $28.51 I hope I helped </span>
Answer:
Since is a bilateral test the p value would be:
Step-by-step explanation:
Information given
n=100 represent the random sample taken
estimated proportion of the readers owned a particular make of car
is the value that we want to test
z would represent the statistic
represent the p value
Hypothesis to test
We need to conduct a hypothesis in order to test if the true proportion is 0.31 or no.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
And replacing we got:
Since is a bilateral test the p value would be:
The population in 1992 was 83 mill....population is 1996 was 88 mill...
so in 4 years (from 1992 to 1996), the population rose by (88 mill - 83 mill) = 5 mill
Thats 5,000,000 / 4 = 1,250,000 per year.
so in 2013 (17 years from 1996), the population would be :
83 mill + 1,250,000(17) = 83 mill + 2,125,000 = 85,125,000 <==
Answer:
cylinder: v= 6616.19
cone: v=4539.6
Step-by-step explanation:
cylinder: π r²h
pi= 3.14
radius/r=9
height/h=29
29* 9² * π= 6616.19
cone: π r²
pi= 3.14
radius/r=17
height/h=15
π * 17² * 15=4539.6
hope this helps :) have a nice day !!
