<h2>Answer with explanation:</h2>

We know that population is a universe set that represents all individuals related to a required particular characteristic where as a sample is a part of that population represents the whole population.

Given : (a) Based on a randomly selected group of 500 patients with high cholesterol, it was found that 67% have heart disease.

Here, 500 patients are representing a part of population of patients.

Hence, its a sample.

(b) An investigation of 150 randomly selected local restaurants concluded that 42% of local restaurants have serious health code violations.

Here, 150 randomly selected local restaurants are representing a part of population of local restaurants.

Hence, its a sample.

What is the width of the rectangle shown below? <br>4x + 3 <br>A = 8x2 – 10x – 12
ozzi

Answer:

<h2><em>2x-4</em></h2>

Step-by-step explanation:

Area of a rectangle = Length * Width

Given parameters

Area A = 8x2 – 10x – 12

Length of the rectangle = 4x+3

Required

Width of the rectangle.

Substituting the given parameters into the formula

8x2 – 10x – 12  = (4x+3)*width

width = 8x2 – 10x – 12 /4x+3

S

Factorizing the numerator

8x² – 10x – 12

= 2(4x²-5x-6)

= 2(4x²-8x+3x-6)

= 2(4x(x-2)+3(x-2))

= 2(4x+3)(x-2)

Width = 2(4x+3)(x-2)/4x+3

Width = 2(x-2)

Width = 2x-4

<em>Hence the width of the rectangle is 2x-4</em>

11 pounds 13 ounces = ounces
lawyer [7]
1 pound = 16 ounces so let's go ahead and convert 11 pounds to ounces by multiplying by 16. 11×16=176 and then add 13 to that 176+13=189

so 12 pounds and 13 ounces= 189 ounces

Indigo Depot is having a clearance sale of their fall items. A jacket that originally cost $120 before any discount is on sale f
Sauron [17]

Answer:

The final price is $66.

Step-by-step explanation:

This question can be solved by a rule of three.

The initial price was of $120.

Initially, there was a discount of 15%. Then, there is another discount on the initial price. So the total discount is of 15+30 = 45%.

So the final price will be 100-45 = 55% = 0.55 of the initial price.

So

$120 - 1

x - 0.55

x = 0.55*120 = 66

The final price is $66.
