Answer:

a.  The difference is important but the question does not make sense

b. Yes, it makes sense to ask if the difference is statistically significant.

c. Please check explanation

Step-by-step explanation:

From the question, we identify the following relation;

: = 0

: ≠ 0

a) The difference is important as asked, but the cultural atmosphere difference of over 30 years makes the question somehow not making sense

b) Yes, it makes sense. In order to answer, it is necessary to know the sample size of the year  2000 survey.

We can answer the question on the basis of the information given.

c) We proceed here as follows;

α = 0.05 , = 1.96 ( This is the critical value)

Thus, z = (0.74-0.36)/√(0.36-0.64)/1000 = 25.03

We make the following conclusions; Since 25.03 > 1.96, the null hypothesis  is rejected which means that the proportion of people who think being well officially is important has changed since 1970.

B

Answer:

A

Step-by-step explanation:

When the given two triangles would be joined they will form the image as given in option B

Name of the quadrilateral would be: (A) rectangle

3 2/3 ÷ 1 1/4

Make the two mixed fractions into an improper fraction

Denominator times whole number. 3*3=9. Add 9 with the numerator. 9+2=11

1*4=4 . 4+1=5

11/3  ÷ 5/4

Flip over the second fraction only when dividing

11/3 *4/5

Multiply the numerator together. Multiply the denominator together.

11*4=44

3*5=15

44/15 or 2 14/15

Answer: 44/15 or 2 14/15

Step-by-step explanation:

Answer:

To make 16 pancakes, we would multiply each of the initial measurement of the ingredients by 16.

To make 4 pancakes, we would multiply each of the initial measurement of the ingredients by 4.

To make 12 pancakes, we would multiply each of the initial measurement of the ingredients by 12.

see explanation below

Step-by-step explanation:

If the ingredients to make 1 pancake is as follows:

1 1/2  cups all-purpose flour; 31/2 teaspoons baking powder; 1 teaspoon salt.

1 tablespoon white sugar.; 1 1/4 cups milk; 1 egg; and 3 tablespoons butter.

Then to make 16 pancakes, we would multiply each of the initial measurement of the ingredients by 16.

cups all-purpose flour =16× 1 1/2

=  16×3/2 = 24

teaspoons baking powder = 16 ×7/2 = 56

teaspoon salt = 1×16 = 16

tablespoon white sugar= 1×16 = 16

cups milk= 16×5/4 = 20

egg= 1×16 = 16

tablespoons butter= 3×16 = 48

Then to make 4 pancakes, we would multiply each of the initial measurement of the ingredients by 4.

cups all-purpose flour =4× 1 1/2

=  4×3/2 = 6

teaspoons baking powder = 4 ×7/2 =14

teaspoon salt = 1×4 = 4

tablespoon white sugar= 1×4 = 4

cups milk= 4×5/4 = 5

egg= 1×4 = 4

tablespoons butter= 3×4 = 12

Then to make 12 pancakes, we would multiply each of the initial measurement of the ingredients by 12.

cups all-purpose flour =12× 1 1/2

=  12×3/2 = 18

teaspoons baking powder = 12 ×7/2 =42

teaspoon salt = 1×12 = 12

tablespoon white sugar= 1×12 = 12

cups milk= 12×5/4 = 15

egg= 1×12 = 12

tablespoons butter= 3×12 = 36

The operation applied is multiplication with each fraction.

Answer:

Step-by-step explanation:

Use pythagorean theorem to solve for x.

Thus:

Where,

a = 6

b = x = ?

c = 15

Plug in the values into the equation

Subtract 36 from each side

Take the square root of both sides
