Answer:
Part A: A
Part B: A
Step-by-step explanation:
1)
the inequality should be less than or equal to, since we need to find how many are left
now, the answer B is wrong, since there can't be negative 56, since Xander collected some cans, though he still must collect a few
thus, the answer is A
2)
A again is correct, since it represents:c ≤ 56
B represents c ≥ 56
C represents c ≤ –56
D represents c ≥ -56
Answer:
a) In the explanation.
b) P=0.09714
c) P=0.0866
d) p=0.208
Step-by-step explanation:
a) The sampling distribution will have this properties:
1 - The sampling distribution of a proportion is equal to the binomial distribution.
2 - The mean of the sampling distribution will be equal to the proportion of the population (0.328).

3 - The standard deviation will be equal to the square root of the product of the proportion and its complementary, divided by the sample size.

B) The fraction with sample proportion of 0.45 or higher is

C) The fraction with sample proportion of 0.20 or lower is

D) The value of p that cuts off the lower 10% of the distribution corresponds to z=-1.28.
Then we have

Answer:
1.85 gallons
Step-by-step explanation:
1 gallon = 3.785 liters
(7 liters)/(3.785 liters/gallon) = 1.85 gallons
Answer:
y = -
x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y - 12 = 2x - 3 ( add 12 to both sides )
y = 2x + 9 ← in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute (2, 3) into the partial equation
3 = - 1 + c ⇒ c = 3 + 1 = 4
y = -
x + 4 ← equation of perpendicular line
