The answer is C.
x=2
y=-30
(2;-30)
Answer: Yes, this indicate the proportion of adult americans that attended college and believe in extraterrestrials is higher than the proportion that did not attend college.
Step-by-step explanation:
Since we have given that
Hypothesis:

n₁ = 100
x₁ = 37
So, 
n₂ = 100
x₂ =47
So, 
At 0.01 level of significance, z = 2.33
So, test statistic value would be

Since, 2.33>-1.44
Hence, we will reject the null hypothesis.
Therefore, Yes, this indicate the proportion of adult americans that attended college and believe in extraterrestrials is higher than the proportion that did not attend college
The sequence is 2n if we're finding a pattern. multiply the previous number by 2 to get the next.
There are 10 digits possible for each of the 4 places .
So the number of digits possible is 10^4 = 10,000
Answer:
13.896 kg
Step-by-step explanation:
You can find the mass of the bar by first finding the volume.
V = BH
where B = area of the base (the trapezium), and
H = height (distance trapezium between bases)
The area of a trapezium is
A = (b1 + b2)h/2
where b1 and b2 are the lengths of the bases of the trapezium (the parallel sides), and
h = the altitude of the trapezium (distance between the bases of the trapezium)
V = (b1 + b2)h/2 * H
V = (12 cm + 6 cm)(5 cm)/2 * 16 cm
V = 720 cm^3
The volume of the bar is 720 cm^3.
Now we use the density and the volume to find the mass.
density = mass/volume
mass = density * volume
mass = 19.3 g/cm^3 * 720 cm^3
mass = 13,896 g
Now we convert grams into kilograms.
1 kg = 1000 g
mass = 13,896 g * (1 kg)/(1000 g)
mass = 13.896 kg
Answer: 1.3896 kg
