Step-by-step explanation:

Assuming that the mountain is of constant height, the climber would have climbed approximately 3 miles.

The mountain climber climbed 15,840 feet on her way to the summit. After converting the feet to miles, it was determined that the climber had climbed 3 miles.

1. Convert the 15,840 feet to miles:

2. Divide the total number of feet (15,840) by the number of feet in a mile (5,280):

3. The answer is 3 miles.

This was calculated by dividing the total number of feet (15,840) by the number of feet in a mile (5,280). Overall, the mountain climber climbed 3 miles on her way to the summit.

Answer:

The correct answers are:

Part A: For State A, the median is 36; Q1 is 35; Q3 is 37; the lowest value is 34; and the highest value is 38. For State B, the median is 25; Q1 is 23; Q3 is 38; the lowest value is 26; and the highest value is 65.

Part B: State A has a symmetric box plot; State B does not.

Explanation:

To find the five number summary for each set, we must first order the numbers from least to greatest:

State A: 34, 35, 35, 35, 36, 36, 36, 38, 38

The median is the middle value. We can see this is 36. Q1 is the value halfway between the median and the lowest value (do not include the median in this list); this is between 35 and 35, which is 35. Q3 is the value halfway between the median and the highest value (do not include the median in this list); this is between 36 and 38, which is 37. The lowest value is 34, and the highest value is 38. This is a symmetric plot, since there is 1 unit between the lowest value and Q1; 1 unit between Q1 and the median; 1 unit between the median and Q3; and 1 unit between Q3 and the highest value.

For State B: 20, 22, 24, 24, 25, 25, 26, 50, 65

The median, or middle value, is 25. Q1, halfway between the median and the lowest value, is 23 (between 22 and 24). Q3, halfway between the median and the highest value, is 38 ((26+50)/2 = 76/2 = 38). The highest value is 65 and the lowest value is 20. This box plot is not symmetric; this is because there are 3 units from the lowest value to Q1, 2 units from Q1 to the median, 13 units from the median to Q3, and 27 units from Q3 to the highest value.

Step-by-step explanation:

The solution to the IVP given by y''+y=t, y(0)=1, y'(0)=-2 is y(t) = cos(t) - (3/2) sin(t) + (1/2) t.

To solve the Initial Value Problem, we can use the method of undetermined coefficients, which involves assuming a particular form for the solution to the non-homogeneous equation y'' + y = t, and then finding the coefficients of the terms in that form by substituting it back into the equation.

First, we find the general solution to the homogeneous equation y'' + y = 0

The characteristic equation is r² + 1 = 0, which has solutions r = ±i. Therefore, the general solution to the homogeneous equation is

y_h(t) = c₁ cos(t) + c₂ sin(t),

where c₁ and c₂ are constants determined by the initial conditions.

Next, we assume a particular form for the non-homogeneous solution, based on the form of the right-hand side t. Since t is a linear function, we assume that the particular solution has the form

y_p(t) = a t + b.

Substituting this into the differential equation, we get

y''_p + y_p = t

2a + (at+b) = t.

Equating coefficients, we get

a = 1/2, b = 0.

Therefore, the particular solution is

y_p(t) = (1/2) t.

The general solution to the non-homogeneous equation is then the sum of the homogeneous and particular solutions

y(t) = y_h(t) + y_p(t)

= c₁ cos(t) + c₂ sin(t) + (1/2) t.

To determine the constants c₁ and c₂, we use the initial conditions:

y(0) = c₁ cos(0) + c₂ sin(0) + (1/2) (0) = c₁ = 1,

y'(0) = -c₁ sin(0) + c₂ cos(0) + (1/2) (1) = c₂ - (1/2) = -2,

so c₂ = -3/2.

Therefore, the solution to the IVP is

y(t) = cos(t) - (3/2) sin(t) + (1/2) t.

According to the question and after using the Pythagorean theorem the length of one side of the roof is 7.416 metres.

The Pythagorean Theorem is a mathematical formula used to determine the length of the sides of a right triangle. It is named after the Greek mathematician Pythagoras, who is credited with discovering the formula in the 6th century BC. The theorem states that the sum of the squares of the two shorter sides of the triangle is equal to the square of the hypotenuse (the longest side of the triangle). In equation form, it is expressed as a² + b² = c², where a and b are the lengths of the two shorter sides of the triangle and c is the length of the hypotenuse.

We know that the hypotenuse is 8 metres (the width of the shed) and the two shorter sides are 3 metres (the height of the walls) and y (the length of the side of the roof).
Therefore, using the Pythagorean theorem, we have:
3² + y² = 8²
9 + y² = 64
y² = 55
y = √55
y = 7.416 metres
Therefore, the length of one side of the roof is 7.416 metres.

Answer:

y=3x+4

Step-by-step explanation:

Slope-intercept form is written as y=mx+b

m = the slope

slope is rise over run or (y2-y1)/(x2-x1). We need to choose which y value is y2 and the corresponding x value is the x2. If -2 is y2, then:

x2 = -2

y1 = 1

x1 = -1

then plug in the values.

(-2-1)/(-2-(-1))

-3/-1 = 3

m =3

then plug in values for the first equation. you can use any point on the line.

y = 3x+b

4 = 3*0 +b

4=0+b

b = 4

then write it with out x or y

Step-by-step explanation: i just did 450 / 5, 9, and 10

Step-by-step explanation:

the most common form of line equation is

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other. it tells us how steeply inclined the line is, and in what direction (up = + or down = -).

b is the y-intercept (the y value when x = 0). so, the point (0, y), and it tells us how high above or low below the x-axis the line is going.

and the y values in the table ? well, as the equation says, y = 2x + 1.

you take the x value, put it into the place of x in the equation, and then calculate y. that is how functions work.

so,

Homemade lemonade containing bits of pulp and seeds would be considered a heterogeneous mixture.

Homogeneous mixtures have a uniform composition throughout, meaning that the different components are evenly distributed at a microscopic level. In the case of homemade lemonade containing bits of pulp and seeds, the presence of visible bits of pulp and seeds indicates that the mixture is not uniform. The pulp and seeds are not evenly distributed and can be easily observed as separate entities within the lemonade. Therefore, the mixture is considered heterogeneous.

Answer:

$36

Step-by-step explanation:

If the cleats were on sale for 45% off, that means they were 55% "on." Therefore, you have to multiply 80 by 0.55* to get how much they cost.

80 x 0.55 is 44.

To get the value of the discount, you subtract 44 from 80, which is 36.

The cleats sold for $44, and there was a $36 discount.

*you multiply by 0.55 because it is 55 percent. Percent means "per every hundred." That's why you have to divide 55 by 100 to get 0.55.

An alternate way to solve this is to multiply 80 by 55 and then divide the result by 100, but you'll still get 44.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The side length of the square is a= 24 cm

Area of square = a²

Now let us find the area of circle

Diameter of circle is 24cm

Radius=24/2=12 cm

Area of circle=πr²

=3.14×12²

Step-by-step explanation:

Step-by-step explanation:

To figure out the variance, subtract 82.5 from the mean, which is 5.5 and then divide by N, which is the value of numbers, (in this case 10) minus 1. The result is a variance of about 9.17. Standard deviation is the square root of the variance so that the standard deviation would be about 3.03.Calculate the mean.

Subtract the mean from each observation.

Square each of the resulting observations.

Add these squared results together.

Divide this total by the number of observations (variance, S2).

Use the positive square root (standard deviation, S).
