Complete question :

Cal Amity decided to survey 880 inhabitants of the Kingdom so that he could have a confidence level of 95% and a margin of error of 3%. He found that 72% of his sample answered "yes" to the second survey question, which was, "Have you done anything, or will you do anything, to prepare your kitchen for Gourmando's visit?"

Mr. Amity can infer that, most likely, between _[blank A]_ and _[blank B]_ inhabitants of the Kingdom have done, or will do something, to prepare their kitchen before Gourmando's visit.

If a population is 5000

Answer:

blank A: 3450

blank B: 3750

Step-by-step explanation:

Number of inhabitants surveyed = 880

Population size = 5000

Error margin = 3%

Percentage that answered 'yes' = 72%

The confidence interval :

Mean ± Error margin

Lower Bound = 72% - 3% = 69% = 0.69

Upper bound = 72% + 3% = 75% = 0.75

Since the question want us know the overall inhabitants of the kingdom who fall between this interval :

Blank A = lower boundary = 0.69 * 5000 = 3450

Blank B = upper boundary = 0.75 * 5000 = 3750

Answer:

I would do C because 2/3 is close to a whole so then you would get -3 and 1/4  is close to 0 so just keep 18 the same which would be -18 so -18 divided by -3 would be correct

Answer:

150°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° ( n - 2) ← n is the number of sides

Here n = 12, then

sum = 180° × 10 = 1800°

Since there are 12 interior angles, then

size of each interior angle = 1800° ÷ 12 = 150°

The velocity of the train is 30 km/h west.

Velocity can be determined by dividing the total displacement travelled by the total time travelled. The direction of travel is also added.

Velocity = 120 km / 4 hours = 30 km/h west.

Answer:

Hypotenuse x = 10 unit

Step-by-step explanation:

Given:

Two equal sides = 5√2

Find:

Hypotenuse x

Computation:

Using Pythagorean theorem;

Hypotenuse = √Base² + Perpendicular²

Hypotenuse x = √(5√2)² + (5√2)²

Hypotenuse x = √50 + 50

Hypotenuse x = √100

Hypotenuse x = 10 unit

Answer $100 each

Step-by-step explanation:

2500/25

Answer:  2500/25

Each member pays $100

============================================

Explanation:

The slash symbol means division. It's the same as saying 2500 ÷ 25

The expression 2500/25 simplifies to 100, which means that each member must pay $100. If you had 25 members paying $100 each, then 25*100 = 2500 dollars is the total amount of money paid.

So in short, you divide the total cost over the number of members.

-5x-3

Step-by-step explanation:

-5x+6-9=-5x-3

The inequality that describes all the solutions to the given inequality expression is x > 4

Given the inequality expression -5x + 6 < 2(-3 − x)

Expand the right-hand side of the ineqality

-5x + 6 < -6 - 2x

Collect the like terms

-5x + 2x < -6 - 6

-3x < -12

Divide both sides by -3

-3x/-3 > -12/-3

x > 4

Hence the inequality that describes all the solutions to the given inequality expression is x > 4
