Answer:

CORRECT OPTION is (C) The flight will be late on one of the three days.

Step-by-step explanation:

The 7am flight from Dallas to Chicago is on time 75% of the time.

A spinner with four sections was created by Fran to simulate this scenario.

Since the 4 sections were equal, it means each section was 25% of the spinner.

3 sections were shaded. That implies 25 × 3 = 75% of the spinner was shaded area.

This coincides with the 75% probability that the flight is on time on a given day.

In other words, if the spinner's pointer lands on shaded area, the flight will be on time. If the pointer lands on an unshaded portion, the flight will be late.

Now Fran spun the spinner 3 times so she has 3 outcomes. The outcomes are:

- Shaded   - Shaded   - Unshaded

CORRECT OPTION is (C) The flight will be late on one of the three days.

Answer:

640 tickets.

Step-by-step explanation:

8hours × 80 = 640

There are 640 tickets are sold in 8 hours.

What is Proportional?

The equality between two ratio is called Proportional.

Given that;

Number of hours for selling number of tickets.

Since, To check the relationship is proportional or not, we check the equality between two given ratio.

Hence, The ratio are;

Number of hours : Number of Tickets

= 3 : 240 : : 5 : 400

It can be solve as;

= 3/240 = 5/400

= 1/80 = 1/80

= 1:80 : : 1:80

Thus, The given relationship between the number of tickets sold and the number of hours is proportional.

Now, Let number of tickets in 8 hours = x

Then, By definition of proportional we get;

⇒ 3 : 240 :: 8 : x

Solve the proportional as;

⇒ 3/240 = 8/x

⇒ x = 8 × 80

⇒ x = 640

So, There are 640 tickets are sold in 8 hours.

Answer:

Step-by-step explanation:

The required equation  that can be solved to find the number of days, d, it will take for the plant to be 65 cm tall is d=  [tex]\frac{5.5\times 65}{11}\\[/tex]

From the question given, we are told that when testing fertilizers on a plant that is 11 cm tall, it is growing at a rate of 2 cm/day. This can be expressed as:

We can get the number of days it will take the 11cm plant to grow:

11cm = x

2cm = 1 day

[tex]2x = 11 * 1\\2x = 11\\x = 11/2\\x = 5.5 days\\[/tex]

Since it will take 5.5days for 11 cm plant tall to grow, to calculate the number of days 'd' it will take a 65cm plant tall to grow, we can say:

11cm = 5.5days

65cm = "d"

Cross multiply

[tex]11d = 5.5 \times 65\\d = \frac{5.5\times 65}{11}\\[/tex]

Hence the required equation  that can be solved to find the number of days, d, it will take for the plant to be 65 cm tall is d=  [tex]\frac{5.5\times 65}{11}\\[/tex]

Answer:

172.72 centimeters

Step-by-step explanation:

1. 5 ft. = 60 in.

2. 60 in. + 8 in. = 68 in.

3. 68 x 2.54 = 172.72

4. add unit of measurement to your answer

Henry's height in centimeters is 172.72 cm

"A process of finding the value of a single unit, and based on this value we can find the required value. "

For given question,

Henry measured 5 feet 8 inches tall.

There are 2.54 centimeters in 1 inch.

that is, 1 inch = 2.54 cm

First we convert Henry's height in inches.

We know that 1 feet =  12 inches

⇒ 5 feet = 60 inches

so, Henry's height in inches would be,

5 feet 8 inches

= (60 + 8) inches

= 68 inches

From given, 1 inch = 2.54 cm

⇒ 68 inches = 172.72 cm

Therefore, Henry's height in centimeters is 172.72 cm

Step-by-step explanation:

Given

[tex]f(x) = \frac{x^2 - 2x}{x^2 - 4}[/tex]

Solve for f(x) for all given values of x

First, we need to simplify f(x)

When the output value of a real-valued function, f(x), is equal to f(-x), for all values of x inside the domain of f, the function is said to be an even function.

It is claimed that a real-valued function f(x) is an odd function when, for all values of x in the domain of f, the output value of f(-x) is equal to the negative of f(x).

Given:

As, we know the first graph graph of an odd function is at the same distance from the origin but in opposite directions and, graph of an even function remains the same after reflection about the y-axis.

So, The polynomial function for this graph is of odd degree and the leading coefficient is negative.

and, The polynomial function for this graph is of even degree and the leading coefficient is negative.

Step-by-step explanation:

Answer:

The first covered digit = x = 3

The last covered digit = y = 2

The total price on the receipt = $367.92

Step-by-step explanation:

Given data:

total cost = $ * 67.9*

First we check for the multiples of 72

9 × 8 = 72

Let

the first covered digit be denoted by x

the last covered digit be denoted by y

Solution

First we find the last covered digit

If a number should be divisible by 8,

It must be a multiple of 8

From the given price:

The last 3 digits = 79*

number in multiples of 8

7.9* = 7.20 + 0.64+ 0.08

7.9* = 7.92

Therefore, the last two digit is 2.

Next We find the first covered digit.

If a number is divisible by 9, it is a multiple of 9

The first digit = x  would be determined as:

= x + 6 + 7 + 9 + 2

= x + 24

= x + 24

multiple of 9 nearer to 24 = 27

27 = x + 24

x = 27 - 24

x = 3.
