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

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

Answer:

Angle A equals 59 degrees.

Step-by-step explanation:

sin^-1(6/7)=Angle A

Therefore, Angle A equals 59 degrees.

[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.

Answer:

The area of the trapezoid:

A = (base1 + base2) x height/2

  = (6 + 12) x 8/2

  = 18 x 4

  = 72

Answer:

y=8

n=1.5

Step-by-step explanation:

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.

Answer:

x + 10 = 24

Step-by-step explanation:

In the figure attached,

There are two external points A and B.

Fro point A two tangents AD and AE have been drawn and From point B tangents BE and BC have been drawn.

Since AD = 10 units,

Therefore, AE = 10 units

(Since tangents drawn from a point to a circle are same in measure, therefore, AD = AE)

Therefore,

BE = AB - AE

Since BE = BC

So BC = AB - AE

       x = 24 - 10

x + 10 = 24

Therefore, (x + 10) = 24 will be the equation to be used to solve for x.

Answer:

41.67% probability that a student has a dog given that they have a cat

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: having a cat.

Event B: having a dog.

12 of 27 students have a cat:

This means that [tex]P(A) = \frac{12}{27}[/tex]

5 students who have a cat and a dog.

This means that [tex]P(A \cap B) = \frac{5}{27}[/tex]

What is the probability that a student has a dog given that they have a cat?

[tex]P(B|A) = \frac{\frac{5}{27}}{\frac{12}{27}} = \frac{5}{12} = 0.4167[/tex]

41.67% probability that a student has a dog given that they have a cat

Answer:

288 students can be served

Step-by-step explanation:

Looking at the donation made by the ice cream parlor, we want to know the number of students to be served.

We need to achieve a consistency in units first. What I mean by this is that all our units must be the same.

The parlor donated 6 containers with each container holding 3 gallons. The amount donated is thus 3 * 6 = 18 gallons of ice cream

Mathematically, there are 16 cups in a gallon. Thus, the amount of cups donated by the parlor would be 16 * 18 = 288 cups

Now since 1 student takes 1 cup of ice cream, the number of students that the donation can serve is 288/1 = 288 students

The answer is false.

The square of 2.8 is actually 7.83999 or 7.84 if rounded.

To get this, we simply bring 2.8 to the power of 2.

2.8 x 2.8 = 7.8399

Therefore, the answer would be false since the actual square of 2.8 is 7.84

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

A: 55.5

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.

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

The value of x is -1 and y is -5

Step 1) Divide the figure into shapes

Large rectangle: 5 x 12

Smaller rectangle: 4 x 6

Square: 2 x 2

Triangle: 4 x 3

Step 2) Find the area of each shapes

Large rectangle: A = 5 x 12 = 60

Smaller rectangle: A = 4 x 6 = 24

Square: A = 2 x 2 = 4

Triangle: A = 1/2 x 4 x 3 = 6

Step 3) Add all of the areas together

A = 60 + 24 + 4 + 6 = 94 square miles
