Answer: 2.25 or 2  1/4 pound of walnut

Step-by-step explanation: So here you need to figure out how many pound of walnut can you purchase with 1 dollar first. To do that, you need to -- 3.75 ÷ 3/4 which you can convert to 3.75 ÷ 0.75 and the answer would be 5.

Now if you do this -- 11.25 ÷ 5 = 2.25

So the answer is 2.25 or 2 and 1/4 pound of walnut

Any given Y(n) among the set of Y1, Y2, ..., Y100, the probability of Y(n) being less than 1.9 is 0.475.

a) To compute P[2Y < 1.9], where Y is a Uniform(0, 2) random variable, we need to find the probability that twice the value of Y is less than 1.9. The Uniform(0, 2) distribution has a constant probability density function of 1/2 within the interval (0, 2). Since Y is uniformly distributed, the probability that Y takes any specific value within (0, 2) is equal.

To calculate the probability, we need to find the proportion of the interval (0, 2) where 2Y is less than 1.9. Dividing 1.9 by 2 gives us 0.95, and we need to find the proportion of the interval (0, 2) that lies to the left of 0.95. This proportion can be calculated as (0.95 - 0) / 2 = 0.475. Therefore, P[2Y < 1.9] is equal to 0.475.

b) P[Y(n) < 1.9] refers to the probability that a specific random variable, denoted as Y(n), is less than 1.9. Since Y(n) is part of the set of independent Uniform(0, 2) random variables, the probability calculation is the same as in part a). Each Y(n) follows the same distribution, and we can find the proportion of the interval (0, 2) where Y(n) is less than 1.9.

Using the same calculation as before, we determine that P[Y(n) < 1.9] is equal to 0.475. Therefore, for any given Y(n) among the set of Y1, Y2, ..., Y100, the probability of Y(n) being less than 1.9 is 0.475.

Answer:

the cost each of one package of tulip bulbs and one bag of daffodil bulbs is $14 and $19 respectively

Step-by-step explanation:

The computation of the cost of each of one tulip package bulbs and one bag of daffodil bulbs is shown below:

Let us assume the tulip bulbs be x

And, the daffodil bulbs be y

According to the question

7x + 9y = $269.........(1)

7x + 2y = $136..........(2)

Now subtract equation 2 from equation 1

7y = $133

y = $19

Now put the value of y in any of the above equation

7x + 9($19) = $269

7x = $269 - $171

x = $14

Hence, the cost each of one package of tulip bulbs and one bag of daffodil bulbs is $14 and $19 respectively

Step-by-step explanation:

The probability of not selecting a green marble is equal to the total number of non-green marbles in the bag divided by the total number of marbles in the bag.

To calculate the probability: there are three green marbles out of a total of twenty-five marbles, so the probability of selecting a green marble is 3/25.

The likelihood of not selecting a green marble is then 1 - 3/25 = 22/25.

This is equal to 22/25 * 100 = 88% as a percentage.

As a result, P(not green) = 88%

Probability denotes the possibility of something happening. It is a mathematical branch that deals with the onset of a random event. The value ranges from zero to one. Probability has been tried to introduce in mathematics to predict the probability of events occurring. Probability is defined as the degree to which something is likely to occur.

Therefore, the distance between the points (-3, -6) and (5,0) is 10 units. This is option A.

A mathematical procedure called the distance formula is used to calculate the separation between two locations on a plane. The Pythagorean theorem, which asserts that the square of a distance between two locations is equal to the sum of the squares of a difference in their coordinates, is where the formula is derived from.

To utilise the distance formula, you must first have the coordinates of the two places. These coordinates are usually expressed as (x1, y1) and (x2, y2), where x1 and y1 stand for the coordinates of the first point and x2 and y2 stand for the coordinates of the second point, respectively.

d = √((x2 - x1)^2 + (y2 - y1)^2)

How to solve?

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

d = sqrt((5 - (-3))^2 + (0 - (-6))^2)

 = sqrt((8)^2 + (6)^2)

 = sqrt(64 + 36)

 = sqrt(100)

There is no solution to the system. This means that the equation 2 = -2 in the system is inconsistent.

What is a system of equations?

A system of equations is a collection of two or more equations that are solved simultaneously. Each equation in the system represents a constraint or condition that must be satisfied, and a solution to the system is a set of values that satisfies all of the equations in the system simultaneously.

If you attempt to solve a system of equations and you get a statement like 2 = -2, it means that the equations in the system are inconsistent. An inconsistent system of equations has no solution because there is no set of values that can simultaneously satisfy all of the equations.

Hence, as these equations are contradictory, there is no solution to the system. This means that the equations in the system are inconsistent.

Answer:

adjacent. x=55

Step-by-step explanation:

Answer:

Adjacent

x=55

Step-by-step explanation:

Vertical angles are made by the same lines but are opposite of each other. These angles are not opposite, and thus they are not vertical. Adjacent angles, on the other hand, share a common side and vertex. In other words, they touch. So, since these share both a common side and vertex, they are adjacent.

Additionally, the large-angle (that contains the smaller, adjacent angles) is a right angle, meaning that it has a measure of 90 degrees. So, if we know that part of the angle is 35 degrees, then the missing angle must be equal to 90-35. 90-35=55 degrees.

Answer:

120 student

Step-by-step explanation:

We know

45% of the students take the bus to school

100% - 45% = 55%

So, 55% travel by car or walk to school

400 x 0.55 = 220 students

So, 220 student travel by car or walk to school

We know

20 more students walk than travel by car

220 - 20 = 200 students

200/2 = 100 students

100 + 20 = 120 students

So, 120 students walk to school

The term "most specifically" is used to indicate the option that is the most specific or narrowest in meaning among the choices. Let's examine each option in the context of geometry:

a. A minor arc: A minor arc is a portion of a circle that measures less than 180 degrees. It is not the most specific term because it encompasses a range of arc sizes smaller than a semicircle, but it does not provide a narrower definition than other options.

b. A major arc: A major arc is a portion of a circle that measures more than 180 degrees. Similar to a minor arc, it does not provide the narrowest definition among the options.

c. A semicircle: A semicircle is a half of a circle, dividing it into two equal halves. This option is more specific than both minor and major arcs because it refers to a precise geometric shape with a 180-degree angle. However, there is one more option left to consider.

We can use trigonometry to solve this problem. Let's draw a right triangle to represent the situation:

        |\

        | \

   h    |  \   9 ft

        |   \

        |    \

        |     \

        -------

        6 ft

Here, h represents the height on the wall where the ladder touches. We want to find the angle of elevation θ.

Using the right triangle, we can write:

sin(θ) = h / 9

cos(θ) = 6 / 9 = 2 / 3

We can solve for h using the Pythagorean theorem:

h^2 + 6^2 = 9^2

h^2 = 9^2 - 6^2

h = √(9^2 - 6^2)

h = √45

h = 3√5

So, sin(θ) = 3√5 / 9 = √5 / 3. We can solve for θ by taking the inverse sine:

θ = sin^-1(√5 / 3)

θ ≈ 37.5 degrees

Therefore, to the nearest tenth of a degree, the angle of elevation the ladder makes with the ground is 37.5 degrees.

By writting all the numbers as decimals we can see that the lake that lost the least amount of water is the last one.

The first lake lost a fraction of 5/6 of its total water.

The second lake lost the 85% of its water.

The last lake lost a fraction of 246/300 of its water.

We want to see which of these 3 numbers is the smaller one, we can write all of them as decimals ot get:

5/6 = 0.833

85% = 0.85

246/300 = 0.82

With this we conclude that the lake that lost the least amount of water is the last one.

a. The breakeven income level occurs when consumption (C) equals income (Y). So, we can set C equal to Y and solve for Y:

C = Y

20 + (2/3)Y = Y

To isolate Y, we can subtract (2/3)Y from both sides:

20 = (1/3)Y

Next, multiply both sides by 3 to solve for Y:

60 = Y

Therefore, the breakeven income level is $60,000.

b. To find the consumption expenditure at income levels of $40,000 and $80,000, we can substitute these values into the consumption function:

For Y = 40:

C = 20 + (2/3)(40)

C = 20 + 80/3

C = 20 + 26.67

C = 46.67

So, the consumption expenditure at an income level of $40,000 is approximately $46,670.

For Y = 80:

C = 20 + (2/3)(80)

C = 20 + 160/3

C = 20 + 53.33

C = 73.33

Therefore, the consumption expenditure at an income level of $80,000 is approximately $73,330.

c. Graphically, we can plot the consumption function C = 20 + (2/3)Y, where C is on the vertical axis and Y is on the horizontal axis. We can mark the breakeven income level of $60,000, as well as the consumption expenditures at $40,000 and $80,000.

The graph will show a linear relationship between C and Y, with a positive slope of 2/3. The consumption function intersects the 45-degree line (where C = Y) at the breakeven income level. For income levels below $60,000, consumption will be less than income, indicating saving (dissaving) depending on the value of C. For income levels above $60,000, consumption will exceed income, indicating saving.
