Step-by-step explanation:

If each car in the parking has only one color , then the option which cannot be the probability that the selected car will be green is 0.6 , the correct option is (c) .

In the question ,

it is given that ,

total numbers of car in the parking lot = 200 cars

number of white cars = 50

number of red cars = 30

number of silver cars = 20

let the number of green cars be "x" ,

So , the number of green cars possible = 200 - 100 = 100

that means x ≤ 100 .

So , P(green) = x/200

Option(a)

p = 0.2 ,

So , x/200 = 0.2

x = 40

Option(b)

p = 0.1 ,

So , x/200 = 0.1

x = 20

Option(c)

p = 0.6 ,

So , x/200 = 0.6

x = 120

Option(d)

p = 0.5 ,

So , x/200 = 0.5

x = 100 ,

We can see that only option(c) gives the number of green cars as 120 , which is not possible .

Therefore , If each car in the parking has only one color , then the option which cannot be the probability that the selected car will be green is 0.6 , the correct option is (c) .

The given question is incomplete , the complete question

In a parking lot with 200 cars, 50 cars are white, 30 cars are red, and 20 cars are silver. one car will be selected at random from the parking lot. if each car in the parking has only one color, which of the following cannot be the probability that the selected car will be green ?

The function which has real zero at  x = –8 and x = 5 is x² + 3x - 40

Given the real zeroes at x = -8 and x = 5.

Factor theorem states that (x-r) is a factor of the polynomial function f(x) if and only if r is a root of the function f(x).

Since, we know that the root of the function i.e g(x) are -8 and 5 then the function has the following factor:

(x+8) = 0 and (x-5) =0

Zero product property states that if ab = 0 if and only if a =0 and b =0.

By zero product property,

(x+8)(x-5) = 0

Now, distribute each terms of the first polynomial to every term of the second polynomial we get;

x(x - 5) + 8(x - 5)

Now, when you multiply two terms together you must multiply the coefficient (numbers) and add the exponent.

x² + 8x - 5x - 40

Combine like terms;

x² + 3x - 40

therefore, the function  has real zeros at x = -8 and x =5 is x² + 3x - 40

The total compound interest obtained is $756.6.

We are given an initial amount equal to $4,800. This is the principal amount that is denoted by the variable "P". The rate of interest is 5% per annum and is denoted by "r". The interest is compounded annually and denoted by "I". The time duration is 3 years, denoted by the variable "t". Let the final amount be represented by the variable "A". We can use the given formula.

A = P(1 + r)^t

A = $4,800*(1 + 0.05)³

A = $4,800*(1.05)³

A = $4,800*1.157625

A = $5,556.6

The compound interest earned is the difference between the initial and the final amount.

I = A - P

I = $5,556.6 - $4,800

I = $756.6

Hence, the interest amount is $756.6.

The horizontal position for the left edge of the image should Joelle use to center the image is  -4.46 cm .

In the question ,

it is given that ,

the length of the over sized image = 30.51 cm and

the length of the page = 21.59 cm

to find the margin , we subtract the width of the word processor page from the width of the oversized image.

that is

margin = 30.51 - 21.59 = 8.92 cm

Since , we have margin on two side ,that is  horizontal positions to the left most side and horizontal positions to the right of the left most edge of the page . we divide 8.92 by 2 .

= 8.92/2

= 4.46 cm

it is given that the horizontal positions to the right of the leftmost edge of the page are positive,

So , horizontal position for the left edge of the image which Joelle should use to center the image would the negative .

Eve raises exactly $9,500, is it possible for there to be 220 participants in the 5K race = ?

From the question

$20 for each 5K participant and x represents the number of participants in the 5K race. = 20x

$45 for each 10K participant and y represents the number of participants in the 10K race = 45y

if Eve raise 220 participants in the 5k race then the equation will be

20 * 220 + 45y = 9500

If the raft travels the distance between ports a and b after 30 hours and the motorboat travels the distance in 6 hours. After the departure the two boats will after 5 hours 4 minutes.

Given that,

After leaving the port,

Raft travels the distance between a and b ports = 30 hours

Motorboats travels the distance between a and b ports = 6 hours

The triangle formed by their tracks and the line joining their current positions in a right angled triangle.

According to the Pythagoras Theorem,

    a² + b² = c²

⇒ (30)²+ (6)² = c²

⇒ 900 + 36 = c²

⇒ 936 = c²

⇒ c = √936

⇒ c = 30.59

Many solutions for a = c and b = 8.

No solution for a = c and b ≠ 8.

One solution for a ≠ c, b can be anything.

What is solution of equations?

Any value of the variable that makes the Left Hand Side (LHS) and the Right Hand Side (RHS) of the equation equal is considered a solution to the problem. Finding the solution or solutions to an equation is known as solving it.

The two sides of the equation must be identical for all values of x if

ax + b = cx + 8 has an unlimited number of solutions. This suggests that

a = c and b = 8.

The two sides of the equation cannot be equal for any value of x if

ax + b = cx + 8 has no solutions. The only way this is possible is if

a = c and b ≠ 8, therefore b can be anything other than 8.

If there is exactly one solution to the equation ax + b = cx + 8, then a ≠ c, meaning that 'a' can be anything other than c. In this situation, 'b' is not constrained in any way (b can be anything).
