Express the confidence interval (0.086 comma 0.130 )in the form of ModifyingAbove p with caret minus Upper E less than p less than ModifyingAbove p with caret plus Upper E.
Answer:
C.I = 0.108 ± 0.022
Step-by-step explanation:
In this case, we are given a symmetric confidence interval, and the sample proportion p', is derived by finding the average of the two values.
Therefore, the sample proportion will be:
[tex] p' = \frac{0.086 + 0.130}{2} [/tex]
[tex] = \frac{0.216}{2} [/tex]
= 0.108
p' = 0.108
To find the margin of error, we have:
M.E = ½ * length of confidence interval
Where length of confidence interval = 0.130 - 0.086
= 0.044
Therefore,
[tex] M.E = \frac{1}{2} * 0.044 = 0.022 [/tex]
Margin of error = 0.022
The confidence interval is expressed as:
p' ± M.E
= 0.108 ± 0.022

Devon purchased one bag of dog food and three bags of cat food. Each bag of dog food weighs x pounds and each bag of cat food weighs half as much as the bag of dog food. The total weight of Devon's purchase is 32.5 pounds. The equation x+3(x/2)=32.5 can be used to determine the weight of the dog food and cat food. What is the weight in pounds of one bag of cat food?
Answer:
A pound of cat food will weigh 6.5 pounds
Step-by-step explanation:
Firstly, we need to get the value of x. Thus, let’s solve the equation at hand;
x + 3x/2 = 32.5
x + 1.5x = 32.5
2.5x = 32.5
x = 32.5/2.5
x = 13
Now from the question, we are made to know that a pound of cat food measures half of what a pound of dog food measures
Since we calculate a pound of dog food to weigh 13 pounds, a pound of cat food will weigh = 13/2 = 6.5 pounds

Solve the system of linear equations by substitution.
y=−4x−9
4x−y=1
Answer:
x=-1, y=-5 ---> (-1, -5)
Step-by-step explanation:
so you want to plug one equation into the other. so start off by plugging y=−4x−9 into the y value of 4x−y=1-----> 4x-(-4x-9)=1. now subtract and isolate x which ends up being x=-1. now plug the x=-1 into either equation and isolate and solve for your y value which ends up being y=-5. you can check you answer by plugging both the x and y you found into one equation and making sure the answer it gives is true. ;)
The solution for equations y=-4x-9 and y=-4x-9 is x=-1, y=-5.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equations are,
y=-4x-9 (1)
4x-y=1 (2)
From equation (1), substitute the value of y in equation (2)
4x-(-4x-9)=1
8x+9=1
8x=-8
x=-1
Substitute x=-1 in equation (1),
y=-4(-1)-9
y=4-9
y=-5

I’m doing work that if I miss one I have to start over. Having lots of issue passing this
Answer:
0.25
Step-by-step explanation:
Probability is the chance you get a certain thing when you pick randomly. In this case, it's asking the probablility of picking someone from a whole student survey that does music or drama.
Looking at the two way table is easy! Out of all grades, 65 are in sports, 25 have music or drama, and 10 has work. Add them all up and get 100.
However, we only found the people in the survey. We need to find the probability of someone in music and drama. So we divide the number of people in all grades who take that class and divide it by the total amount- 25/100, this turns out for the probability to be 0.25.

What is Unitary Method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
There are four walls in a room.
He is able to cover of the walls in the room using 6 rolls of wallpaper.
let x as the number of rolls that each wall requires.

48 cupcakes in 6 boxes=cupcakes per box
Answer:
[tex]\frac{8 cupcakes}{1 box}[/tex]
Step-by-step explanation:
All we have to do for this problem is divide.
48 / 6 = 8
There are 8 cupcakes per box.
Answer: 8 cupcakes per box
Step-by-step explanation: "Per box" means in 1 box, so we can rewrite the given statement using fractions as
48 cupcakes/6 boxes = __ cupcakes/1 box.
To find out what goes in the blank, notice that we
have a 1 in the denominator of our second fraction.
So we want to find a fraction that is equivalent
to 48/6 that has a 1 in the denominator.
If we divide the numerator and denominator of 48/6 by 6,
we get the equivalent fraction 8/1 or 8 cupcakes/1 box.
So now we have 8 cupcakes/1 box = __cupcakes/1 box.
So an 8 must go in the blank which means that the unit rate
for 48 cupcakes in 6 boxes is 8 cupcakes per box.
Point B has coordinates (5,2). The x-coordinate of point Ais - 1. The distance between point A and
point B is 10 units. What are the possible coordinates of point A?
The possible coordinates of point A are 1
(Type an ordered pair. Use a comma to separate answers as needed.)
Answer:
[tex]\large \boxed{(-1,-6),(-1,10)}[/tex]
Step-by-step explanation:
Point A must be on a circle with centre at (5,2) and radius 10.
The centre-radius form for the equation of a circle is
(x – h)² + (y – k)² = r², where
(h,k) = the coordinates of the centre and
r = the radius
Thus, the equation for this circle is
(x - 5)² + ( y - 2)² = 10²
Substitute the value for x and solve for y:
[tex]\begin{array}{rcl}\\(x - 5)^{2} +( y - 2)^{2} &=& 10^{2}\\(-1 - 5)^{2} +( y - 2)^{2} &=& 100\\(-6)^{2} +( y - 2)^{2} &=& 100\\36 +( y - 2)^{2} &=& 100\\( y - 2)^{2} &=& 64\\y - 2 = -8 & \qquad & y - 2 = 8\\y = \mathbf{-6} & \qquad & y = \mathbf{10}\\\end{array}\\\text{The possible coordinates of A are $\large \boxed{\mathbf{(-1,-6),(-1,10)}}$}[/tex]
The figure below shows the circle intersecting the line x = -1 at (-1,-6) and (-1,10).

ABC is an isoscles triangle. Angle A = 40°.
Find measure of Angle B.
40
70
75
180
Answer:
70 degrees
Step-by-step explanation:
total angle in a triangle is 180 degrees
180-40= 140
Angle b and c is total of 140 degrees
they are isosceles so their measurements would be same.
angle b and c is 140÷ 2 = 70
so angle b is 70 degrees
