In a large population, 92% of the households have cable tv. A simple random sample of 225 households is to be contacted and the sample proportion computed. What is the mean and standard deviation of the sampling distribution of the sample proportions
Answer:
the mean and the standard deviation is 0.92 and 0.01808 respectively
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
The mean is 0.92
And, the standard deviation is
= √0.92 × (1 - 0.92) ÷ √225
= √0.92 × 0.08 ÷ √225
= √0.0736 ÷ √225
= √3.27
= 0.01808
Hence, the mean and the standard deviation is 0.92 and 0.01808 respectively

A dolphin jumps from the water at an initial velocity of 16 feet per second. The equation h + -16t^2 + 80t models the dolphin's height at any given time, t. What is the maximum height the dolphin jumps?
Answer:
100feet
Step-by-step explanation:
Given the height reached by a dolphin expressed by the equation is h = -16t^2 + 80t. At maximum height, the velocity is zero, hence;
v(t) = dh/dt = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32
t = 2.5secs
Substitute t = 2.5 into the height formula h = -16t^2 + 80t
h = -16(2.5)^2 + 80(2.5)
h = -100+200
h = 100feet
Hence the maximum height the dolphin jumps is 100feet
If money in a savings account earned 8% interest per annum, how much nterest would be earned on $150.00 over three years?
Answer:
$36
Step-by-step explanation:
Given :
Interest rate, r = 8% = 0.08
Principal, P = 150
Time, t = 3 years
Simple interest = (principal * rate * time)
Simple interest = (150 * 0.08 * 3)
Simple interest = $36

Answer:
(d) (-3, 1)
Step-by-step explanation:
We assume a typo in the problem statement, and that the equations are supposed to be ...
[tex]2x -3y = -9\\-x +3y = 6[/tex]
Adding the two equations gives ...
x = -3
Substituting for x in the second equation gives ...
3 +3y = 6
1 + y = 2 . . . . divide by 3
y = 1 . . . . . . . subtract 1
The solution is (x, y) = (-3, 1).

A triangle has sides with lengths of 26 yards, 76 yards, and 78 yards. Is it a right triangle?
Options:
Yes
No
Answer:
No
Step-by-step explanation:
a^2 + b^2 = c^2
Since 78 is the largest it will be c.
26^2 + 76^2 = 78^2
676 + 5776 = 6084
6452 does NOT = 6084
Since c^2 is larger it is an obtuse triangle.
Voting in Seaside's annual school board elections has been going down by 10% from one election to the next. If 990 parents voted this year, how many will vote 4 years from now?
If necessary, round your answer to the nearest whole number.
Answer:
FV= 676
Step-by-step explanation:
Giving the following formula:
Present value (PV)= 990 parents
Decrease rate (d)= 10% = 0.1 per year
Number of periods (n)= 4
To calculate the future value of votes, we need to use the following formula:
FV= PV / (1 + d)^n
FV= 990 / (1.1^4)
FV= 676
Jessica's cat weighs 7lb. The neighbors cat weighs 1/5 more than Jessica's cat. How much does the neighbor's cat weigh?
Answer:
8.4 lbs

Which ordered pair is a solution of 9(x – 2)2 – 4(y + 5)2 ≥ 36?
(2, –3.5)
(2, 5.5)
(–7.5, –5)
(1.5, –5)
Answer:
its c kiddos
Step-by-step explanation:
The required ordered pair for the solution of an equation [tex]9(x - 2)^2 - 4(y + 5)^2\geq 36[/tex] is (-7.5,-5).
An ordered pair from the options is the solution of the equation [tex]9(x - 2)^2 - 4(y + 5)^2\geq 36[/tex] to be determined.
An ordered pair is defined as the coordinates when put into the equation giving the solution of the equation.
While plotting the curve of the given equation on the graph and also plotting the ordered pair on the graph. It is seen that points (2, –3.5), (2, 5.5), and (1.5, –5) lie on the unshaded portion. While ordered pair (-7.5, -5) lies on the shaded portion.
Thus, the required ordered pair for the solution of an equation [tex]9(x - 2)^2 - 4(y + 5)^2\geq 36[/tex] is (-7.5,-5).

The length of a rectangle is five more than three time its width. The perimeter of a rectangle is 234. What is the width of the rectangle
Answer:
28 units
Step-by-step explanation:
Given data
Let the width be x
The length is =3x+5
Perimeeter= 234
The expression for the perimeter is
P=2L+2W
Substitute
234= 2*x+2(3x+5)
234= 2x+6x+10
Collect like terms
234= 8x+10
234-10= 8x
224=8x
x= 224/8
x=28
Hence the width is 28 units
