At the 2006 Winter Olympics in Torino, Italy, US speed skater Apolo Ohno took the gold medal for the 500m sprint by completing the course in 41.935 s. What was his average speed for this event in m/s.

Answer:

3.75 days

Step-by-step explanation:

To find out how long it takes to consume 13500 watt hours, you would divide 13500 by the number of watt hours consumed per day, which is 3600.

13500 / 3600 = 3.75

So it takes 3.75 days for the light bulb to consume 13500 watt hours.

The quadrilateral's new coordinates will be J(4, 4), K(3, 4), L(1, 1), and M (4,1) when the procedure is applied.

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given coordinates of a quadrilateral J(-4, 4), K(-3, 4), L(-1, 1), M(-4,1)

Reflect in the x-axis

Since,

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

thus new coordinates will be,

J(-4, -4), K(-3, -4), L(-1, -1), M(-4,-1)

Rotate 180 degrees about the origin

Since,

When we rotate a figure of 180 degrees about the origin either in the clockwise or counterclockwise direction, each point of the given figure has to be changed from (x, y) to (-x, -y) and graph the rotated figure.

Thus new coordinates will be

J(4, 4), K(3, 4), L(1, 1), M(4,1)

Therefore, After applying the given operation the new coordinates of the quadrilateral will be  J(4, 4), K(3, 4), L(1, 1), and M(4,1).

Answer:

  y = 3x -1

Step-by-step explanation:

You want the equation of the line through the points (0, -1) and (1, 2), among others.

The y-value when x=0 is the y-intercept. The table shows you it is -1.

The slope is the difference in y-values when x-values increase by 1. For the first two points in the table, the y-value shows an increase of ...

  2 -(-1) = 3

This means the slope is 3.

The slope-intercept equation of a line is ...

  y = mx +b . . . . . . . where m is the slope, and b is the y-intercept

For your line, we have determined m=3, b=-1, so the equation is ...

Answer: 37.33 % of items cost less than $7.5

Step-by-step explanation:

To find the percentage of items that cost less than $7.5, we would need to know the probability distribution function of the cost per item, as well as the specific parameters of the distribution (such as the shape parameter).

Since the information provided is that the cost per item follows an exponential distribution and the mean cost per item is $10.5,

We can use the cumulative distribution function (CDF) of the exponential distribution which is

F(x) = 1 - e^(-λx)

where x is the cost of the item, λ is the rate parameter and e is the base of the natural logarithm.

We know the mean is $10.5 , and in an exponential distribution the mean and the rate parameter are equal, so we can say λ = 1/10.5

To find the percentage of items that cost less than $7.5, we need to find the probability that X < 7.5, which is the same as finding F(7.5)

So, F(7.5) = 1 - e^(-λ*7.5) = 1 - e^(-0.714)

Then, we need to convert this probability to percentage, so we need to multiply it by 100

F(7.5) = (1 - e^(-0.714)) * 100 = 37.33 %

Therefore, 37.33 % of items cost less than $7.5

The ordered pairs that satisfies the linear inequality x < - 3 are (-4, -3) and (-3, -3)

A linear inequality is a mathematical statement that describes a relationship between two or more variables that are not necessarily equal. It is similar to a linear equation, but instead of an equal sign, it uses one of the inequality signs: <, >, ≤, or ≥.

A linear inequality can also be represented graphically on a coordinate plane, by shading the region of the plane that satisfies the inequality. The solution set of a linear inequality is the set of all points that make the inequality true.

A linear inequality can also have infinitely many solutions, no solution or a unique solution. The solution set will be a region in a coordinate plane which is a half-plane, a line or a point depending on the inequality.

In the problem, the inequality x < -3 will have an ordered pair of solution of

(-∞, -3).

The quantity of ribbon that Ali started with was 16/21 feet, based on the mathematical operation of addition.

The basic mathematical operations include addition, subtraction, division, and multiplication.

In the addition operation, two or more addends are added to obtain a result called the sum or total using the equation symbol (=) and the addition operand (+).

The quantity of ribbon attached to the rearview mirror = 2/7

The remaining quantity of ribbon after the attachment = 10/21

The quantity of ribbon Ali started with = 16/21 (2/7 + 10/21)

An inequality to represent the dollar amounts d in cash and prizes Regan can win is p + d ≥ 500.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, Regan won the grand prize at a store giveaway. The grand prize winner is guaranteed to win at least $500 in cash and prizes.

Let d represent the amount of cash in dollars and p represent the amount of prizes.
