Answer:
a
The null hypothesis is [tex]H_o : p = 0.67[/tex]
The alternative hypothesis is [tex]H_a : p \ne 0.67[/tex]
b
The sample proportion is [tex]\^ p = 0.65[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 546
The number of people that use a laptop overnight is [tex]k = 355[/tex]
The population proportion is [tex]p = \frac{2}{3} = 0.67[/tex]
Generally
The null hypothesis is [tex]H_o : p = 0.67[/tex]
The alternative hypothesis is [tex]H_a : p \ne 0.67[/tex]
Gnerally the sample proportion is mathematically represented as
[tex]\^ p = \frac{ k}{n}[/tex]
=> [tex]\^ p = \frac{ 355}{546}[/tex]
=> [tex]\^ p = 0.65[/tex]

Use the equation for the surface area of a cylinder, SA = 2^r2 + 2arh, where r is
the radius and h is the height. Find h if the surface area is 207.24 square inches and
the radius is 3 inches. Use 3.14 for it and round your answer to the nearest whole
number if needed.
Answer:
8inStep-by-step explanation:
the given formula in the question is not correct
here is the correct formula
S. A. =2πr^2 +2πrh
given that S.A=207.24
radius r= 3in
207.24=2*3.142*(3)^2 +2*3.142*(3)h
207.24=56.556 +18.852h
207.24-56.556=18.852h
150.684=18.852h
h=150.684/18.852
h=7.99
Approximately the height is 8in

11. In the figure, AC = 24 and AB = BC. Point D (not shown) is on the line between A and B such that AD = DB.
What does DC equal?
Answer with step-by-step explanation:
If AD = DB, then D would be the midpoint of AB. If AB = BC, then B would be the midpoint of AC. If so, lets add another point called E. E is the midpoint of BC, which would divide AC into fourths. DC = DB + BE + EC. So, DC is 3/4 of 24, which is 18.

a. How many yards did they lose in two plays?
b. How do we represent a loss of 5 yards?
c. How do we represent a loss of 8 yards?
d. What does our addition sentence look like?
e. What is the answer to the question?
Answer:
13
-5
-8
-5+-8
Step-by-step explanation:
a ) they loose 13 yards in two plays.
b )It is represented by - 5 yards.
c) It is represented by - 8 yards.
d) Addition sentence will be ; 8 + 5 = 13
e) The answer will be 13.
It is given that a football team loses 5 yards on one play and then loses 8 yards on the next play.
We have to answer the given questions based on the provided data.
What will be the value if 2 times of 10 is added to 10 ?
The value will be ; 20 + 10 = 30.
As per the question ,
A football team loses 5 yards on 1st game and 8 yards on 2nd game.
Let's give answer to the question ;
a)
Total yards the team lost in two plays
= 8 +5
= 13
b) As the team is loosing 1st play , we can consider it as a negative value.
So ,
It can be represented by x = - 5 yards.
c) As the team is loosing in 2nd play , we can consider it as a negative value.
So ,
It can be represented by x = - 8 yards.
d) The expression for addition can be written as ;
8 + 5 = 13
e) The answer to the question will be equal to 13 yards.
Thus , we can conclude that ;
a ) they loose 13 yards in two plays.
b )It is represented by - 5 yards.
c) It is represented by - 8 yards.
d) Addition sentence will be ; 8 + 5 = 13
e) The answer will be 13.

If L||m find the value of X
Please help me :)
Answer:
x= 12
Step-by-step explanation:
(9x -4)° +(5x +16)° = 180° (int. ∠s, L//m)
9x -4 +5x +16= 180
14x +12= 180 (simplify)
14x= 180 -12 (-12 on both sides)
14x= 168
x= 168 ÷14 (÷14 on both sides)
x= 12

Looking at the equation, 5x + 6 = 46, will
x = 7 make the equation true?
Why or why not?
Answer:
This is not true so x=7 is not a solution
Step-by-step explanation:
5x + 6 = 46
Let x = 7
5*7 +6 = 46
35+6 = 46
41 = 46
This is not true so x=7 is not a solution

3. How many solutions are there to the
equation 2x^2 - 3x +12=0? Tell how
you know.
Answer:
If you're talking about solutions in general (real and imaginary solutions), there is 2, because the fundamental theorem of algebra says that the number of roots of any polynomial is the degree if it's highest power, which is 2.
If you're talking about only real solutions, there is 0. To show that, we can take the discriminant (b^2-4ac) part of the quadratic equation, and plug in the know values. We then get:
(-3)^2-4*2*12
=9-96
=-87
Remember, the discriminant will be taken the square root. Since this is negative, the answer will be imaginary. Therefore, there is no real solution.
A scaled drawing of a rectangle park is 5 inches wide and 7 inches long. The actual park is 280 yards long. What is the area of the actual park in square units?
Area of the actual park is 56000 square yards.
Step-by-step explanation:
A scale drawing of a rectangular park has dimensions as 5 inches width and 7 inches length.
Actual length of the park has been given as 280 yards.
So scale factor used in the drawing is 7 inches
= 280 yards
Or 1 inch = 40 yards
Since width of the rectangular park is = 5 inch
So actual width of the park will be = 5×40 = 200 yards
Now we can calculate the area of the park.
Actual area of the park = Length × Width
= 280×200
= 56000 yards²
Therefore, area of the actual park is 56000 square yards.
