Find the probability of rolling a um greater than 7 given that you rolled an odd number firt

Answers

As the out comes are (3,6), (5,6), (5,3), (5,4), (5,5),(3,5) when you rolled an odd number first so the probability of rolling a sum greater than 7 is 1/6

What is probability and example?

The probability is equal to the variety of possible outcomes. the total number of outcomes that could occur. For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). it will be written as P(heads) = 1/2.

Why do we use probability?

Information about the possibility that something will happen is provided by probability. For instance, meteorologists use weather patterns to forecast the likelihood of rain. Probability theory is utilized in epidemiology to comprehend the connection between exposures and the risk of health outcomes.

There are total 36 possible outcomes of two dices when they are rolled.

N=36

now we have to consider the out comes having sum greater than 7

which are;

(2,6),(3,5),(3,6),(4,4) ,(4,5),(4,6),(5,3),(5,4),(5,5) ,(5,6),(6,2),(6,3),(6,4),(6,5),(6,6)

and now selecting only those having first number is odd

so they are:

(3,5),(3,6),(5,3),(5,4),(5,5),(5,6)

now using probability formula;

Probability = favorable outcomes /total outcomes

value putting;

probability = 6/36

probability =1/6

this is our required answer.

#SPJ4

Probability of rolling an odd number on a single die is 3/6, or 1/2. This is because there are three odd numbers (1, 3, and 5) on a standard six-sided die, and the probability of rolling any given number is 1/6.

What is meant by Probability?

Probability is a metric used to determine how likely an event or result is to occur. A decimal or fraction between 0 and 1 is typically used to express it, with 0 denoting that the event will not occur and 1 denoting that it will occur without a doubt. For instance, the likelihood of rolling a 6 on a conventional six-sided die is 1/6 since there is only one scenario out of the six conceivable events that will result in rolling a 6. By dividing the number of desired outcomes by the total number of potential possibilities, one may compute probability. In general, the more likely an event is to occur, the greater its probability.

The perimeter of a rectangular pool i 110 feet. If the pool i 17 feet wide, find the length of the pool

Answers

It will be 38 feet long

What is perimeter?

The perimeter is the space surrounding a shape's edge.

The sum of the lengths of all the sides in a rectangular shape is its perimeter. P = 2( L+B)

Given that a rectangle's width is 17 feet and its perimeter is 110 feet, the length will be P = 2 (L + B)

110 = 2 (L + 17)

55 - 17 = L.

The pool is therefore 38 feet long.

9x² + 31x+ 20 = ( ? ) ( ? )
2x² +7x-4 = ( ? )( ? )
2x² - 13x-5 = ( ? )( ? )

Answers

Answer: The square root of 169 is 13, so the two solutions for x are:

x = (13 + 13) / 4 = 3.25

x = (13 - 13) / 4 = -0.25

Since the quadratic expression 2x^2 - 13x - 5 equals 0 when x is either 3.25 or -0.25, the factors of this expression are (x - 3.25)(x + 0.25).

In summary, the factors of the first quadratic expression are (x + 1.056)(x + 5.937), the factors of the second expression are (x - 0.75)(x + 3.75), and the factors of the third expression are (x - 3.25)(x + 0.25).

Step-by-step explanation: To find the factors of a quadratic expression, we can use the quadratic formula. The quadratic formula states that for a quadratic expression of the form ax^2 + bx + c = 0, the solutions for x are given by the formula x = (-b ± sqrt(b^2 - 4ac)) / (2a).

In the first equation, a is 9, b is 31, and c is 20. Plugging these values into the quadratic formula, we get:

x = (-31 ± sqrt(31^2 - 4 * 9 * 20)) / (2 * 9)

This simplifies to:

x = (-31 ± sqrt(961 - 720)) / 18

This further simplifies to:

x = (-31 ± sqrt(241)) / 18

We can find the value of the square root by using a calculator or by remembering some common square roots. The square root of 241 is approximately 15.937, so the two solutions for x are:

x = (-31 + 15.937) / 18 = -1.056

x = (-31 - 15.937) / 18 = -5.937

Since the quadratic expression 9x^2 + 31x + 20 equals 0 when x is either -1.056 or -5.937, the factors of this expression are (x + 1.056)(x + 5.937).

We can use the same approach to find the factors of the other two quadratic expressions. For the second expression 2x^2 + 7x - 4, the values of a, b, and c are 2, 7, and -4, respectively. Plugging these values into the quadratic formula, we get:

x = (-7 ± sqrt(7^2 - 4 * 2 * -4)) / (2 * 2)

This simplifies to:

x = (-7 ± sqrt(49 + 32)) / 4

This further simplifies to:

x = (-7 ± sqrt(81)) / 4

The square root of 81 is 9, so the two solutions for x are:

x = (-7 + 9) / 4 = 0.75

x = (-7 - 9) / 4 = -3.75

Since the quadratic expression 2x^2 + 7x - 4 equals 0 when x is either 0.75 or -3.75, the factors of this expression are (x - 0.75)(x + 3.75).

For the third expression 2x^2 - 13x - 5, the values of a, b, and c are 2, -13, and -5, respectively. Plugging these values into the quadratic formula, we get:

x = (13 ± sqrt(13^2 - 4 * 2 * -5)) / (2 * 2)

This simplifies to:

x = (13 ± sqrt(169 + 40)) / 4

In 2017, a company's sales were about $9 million. Sales increased at an approximately constant rate and reached
about $14.5 million in 2020, Estimate the sales in 2026. Show your work.

Answers

Answer: To estimate the company's sales in 2026, we need to find the average increase in sales per year and then use that to predict the sales for 2026.

The total increase in sales from 2017 to 2020 was $14.5 million - $9 million = $<<14.5-9=5.5>>5.5 million.

The number of years from 2017 to 2020 is 2020 - 2017 = <<2020-2017=3>>3 years.

Therefore, the average increase in sales per year was $5.5 million / 3 years = $<<5.5/3=1.83>>1.83 million/year.

Since the average increase in sales per year was $1.83 million/year, we can estimate the sales in 2026 by adding that amount to the sales for each year from 2020 to 2026. For example, the estimated sales for 2021 would be $14.5 million + $1.83 million = $16.33 million. Similarly, the estimated sales for 2022 would be $16.33 million + $1.83 million = $18.16 million, and so on.

Using this method, we can estimate that the sales for 2026 will be $26.73 million.

A. 45 B. 54C. 63D. 70

Answer :

C. 63

Explanation :

As, Lela is using 9 peaches for each pie.

Thus, she used 18 peaches for 2 pies, which is 2 times 9 and 36 peaches for 4 pies, which is 4 times 9. Therefore, to make 7 pies, she would need :

Peaches used for one pie = 9

=> Peaches used for 7 pies = 9 × 7

=> Peaches needed for 7 pies = 63

Hence, she will need 63 peaches to make 7 pies.

For a project in his Geometry class, Feng uses a mirror on the ground to measure the height of his school’s flagpole. He walks a distance of 8.65 meters from the flagpole, then places a mirror on flat on the ground, marked with an X at the center. He then steps 1.1 meters to the other side of the mirror, until he can see the top of the flagpole clearly marked in the X. His partner measures the distance from his eyes to the ground to be 1.65 meters. How tall is the flagpole? Round your answer to the nearest hundredth of a meter.

Answers

The height of the flagpole, found using the ratio of the sides of similar triangles is 12.975 meters

What are similar triangles?

Similar triangles are triangles  in which two angles of one triangle  are congruent to two angles in the other triangle, such that they have the same shape.

The parameters that can be used to find the height of the flagpole are;

Distance of the mirror from the flagpole = 8.65 meters

Distance of Feng on the other side of the flagpole = 1.1 meters

The height from Feng's eyes to the ground = 1.65 meters

According to the law of reflection, the angle of incident and the angle of reflection are the same

The angle made by Feng and the ground = Angle made by the flagpole and the ground = 90°

The triangle formed by the Feng and the flagpole are therefore similar by AA similarity postulate

The ratio of corresponding sides of similar triangles are the same, therefore;

[tex]\dfrac{1.65}{Height\, of \, the \, flagpole} = \dfrac{1.1}{8.65}[/tex]

[tex]Height\, of \, the \, flagpole = \dfrac{1.65}{1.1} \times 8.65 = 12.975[/tex]
