the answer is, the number of packages of corn purchased

Answer:

C. The number of packages of corn purchased.

Step-by-step explanation:

We have been given that a store sells four 1 1/8-pound ears of corn in a package for $3.59. The expression represents the cost of the corn for a number of packages.

Since the cost of each package of corn is $3.59 and represents the cost of 'p' packages of the corn. So 'p' represents the number of packages of corn purchased.

P(A) = 7/20 P(B) = 7/20 P(A or B) = 49/80, P(A and B)= ?​

Answers

Answer:

P(A and B) = 7/80

Step-by-step explanation:

The given values of the probabilities of the different events are;

P(A) = 7/20

P(B) = 7/20

P(A or B) = 49/80

P(A and B) = Required

We have by probability theory for any event;

P(A or B) = P(A) + P(B) - P(A and B)

Therefore;

P(A and B) = P(A) + P(B) - P(A or B)

Plugging in the values gives;

P(A and B) = 7/20 + 7/20 - 49/80 = 7/80

∴ P(A and B) = 7/80

Cody purchased a car for $4500 that will depreciate 28% a year. Write an exponential growth/decay equation that represents the value of Cody's car overtime. How much will the car be worth in 15 years? Round to the nearest cent.

Answers

Answer:

$32.60

Step-by-step explanation:

This question has to to do with exponential decay. The formula is given as:

y = a(1 - r)^x

y = Value of the material after x years

a = Initial value of the material

x = Time in years

r = rate of depreciation or decay

Therefore,

y = 4500 × (1 - 0.28)¹⁵

y = 4500 × 0.72¹⁵

y = $32.598675906

y = Approximately = $32.60

Therefore the of the car after 15 years = $32.60

Secant tangent angles

Answers

Answer:

148 = x

Step-by-step explanation:

Using the Secant and Tangent Intersection theorem we can say;

38 = 1/2 (x - 72)

38 = 1/2x - 36

74 = 1/2x

(74)/(1/2) = x

148 = x

Consider the sets below.

A {x|x is a polygon}
B {x|x is a triangle}

Which is true?

A ⊂ B
B ⊂ A
Ac = B
Bc = A

Answers

Answer:

B ⊂ A

Step-by-step explanation:

We know that:

A {x|x is a polygon}

So set A is the set of all polygons.

B {x|x is a triangle}

Set B is the set of all triangles.

First, a polygon is a plane geometrical figure made of a finite sequence of straight segments.

For example, a triangle is a polygon, a rectangle is a polygon, etc.

Then, all triangles are polygons, but not all polygons are triangles.

So we can conclude that the whole set B is included in the set A.

Then the correct notation would be:

B ⊂ A

Answer:

B ⊂ A

Answers

The population of Arlington High is increasing. Then the population of Arlington High school after 29 years will be 7579.

What is an exponent?

Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as

y = a(b)ˣ

The population of Arlington High School can be modeled using the equation

[tex]\rm P(t)=3,500(1.027)^t[/tex]

Where t represents the number of years since 2010.

The population of Arlington High is increasing. Because b > 1.

Then the population of Arlington High school after 29 years will be

P(27) = 3500 (1.027)²⁹

P(27) = 7578.98

P(27) ≈ 7579
