A news organization interested in chronicling winter holiday travel trends conducted a survey. Of the 96 people surveyed in the eastern half of a country, 42 said they fly to visit family members for the winter holidays. Of the 108 people surveyed in the western half of the country, 81 said they fly to visit family members for the winter holidays. Construct a 99% confidence interval for the difference in population proportions of people in the eastern half of a country who fly to visit family members for the winter holidays and people in the western half of a country who fly to visit family members for the winter holidays.

Answer:

75% chance

Step-by-step explanation:

Probability always adds to 1.00

Letter grades are always in the form A, B, C, D...

The grades above a C are A, which is a 25% chance and B, which has a 50% chance. Adding these up we get a 75% chance.

#LearnWithBrainly

The probability of getting a grade above a C is 0.75, or 75%.

We have,

To calculate the probability of getting a grade above a C, you need to add the probabilities of getting an A or a B.

Given:

Probability of getting an A (P(A)) = 0.25

Probability of getting a B (P(B)) = 0.50

A grade above a C includes grades of A and B.

Therefore, the probability of getting a grade above a C (P(above C)) is:

P(above C) = P(A) + P(B)

P(above C) = 0.25 + 0.50

P(above C) = 0.75

Thus,

The probability of getting a grade above a C is 0.75, or 75%.

Step-by-step explanation:

Answer: y=7/2 in decimal form 3.500

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2-4*y-(-12)=0

Pull out like factors :

  14 - 4y  =   -2 • (2y - 7)

  Solve  :    2y-7 = 0  

Add  7  to both sides of the equation :  

                     2y = 7

Divide both sides of the equation by 2:

                    y = 7/2 = 3.500

Answer:

Closet #1.

Step-by-step explanation:

Closet #1 is 4x5x8, right? so, 4x5=20, and 20x8=160 feet. Closet #2 is 6x3x8, and 6x3 is 18. That's already less than 20 even before we multiply by 8. So, the answer to your question is Closet #1.

Answer:

Answer: The first closet is larger.

Step-by-step explanation:

Closet #1

V = l × w × h

V = 4 ft. × 5 ft. × 8 ft.

V = 160 cu. ft.

Closet #2

V = l × w × h

V = 6 ft. × 3 ft. × 8 ft.

V = 144 cu. ft.

Compare the size of the closets

160 cu. ft. > 144 cu. ft.

Answer: The first closet is larger.

By "similar," I'm assuming you mean the same thing as "like" terms.  Those are exactly the same (same variables and same exponents) but could have different coefficients (the number in front).

1. N  variables are not the same

2. S  variables are the same, exponents are the same

3. S  same variables; same exponents (x^3 y^2 is the same as y^2 x^3)

Answer:

b= -4

Step-by-step explanation:

On both sides of the equation has distributive property. We need to solve that first. Let's start with the left side of the equation.

*Positive multiplied by a negative equals a negative

-2b+2(b-10)= 2(10+5b)

-2b+2b-20= 2(10+5b)

-20= 2(10+5b)

Now let's solve the right side of the equation

-20= 20+10b

-20  -20

-40 = 10b

-40/10 = 10b/10

b= -4

Answer: Area of the rectangular room = length x Breadth

Length= 18 and Breadth = 12

Therefore the Area required to cover the floor = 18 * 12 = 216 ft2

The area of the rectangular room is given by the equation A = 216 feet²

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the equation will be

The length of the rectangular room = 18 feet

The width of the rectangular room = 12 feet

Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Area of the rectangular room = 18 feet x 12 feet

On simplifying the equation , we get

Area of the rectangular room A = 216 feet²

Therefore , the value of A is 216 feet²

Hence , the area of the rectangular room is 216 feet²

Answer:

the nearest tenth of the cm is 6.9 cm

Step-by-step explanation:

a) Tangent equals sine divided by cosine.  Therefore:

tan(-t) = sin(-t) / cos(-t)

b) Using the fact that sin(-t) = -sin(t) and cos(-t) = cos(t):

tan(-t) = -sin(t) / cos(t)

tan(-t) = -tan(t)

c) A function is symmetric about the origin if f(-x) = -f(x) (in other words, if it's an odd function).  Therefore, y = tan(t) is symmetric about the origin.
