What value of x is in the solution set of the inequality –5x – 15 > 10 20x? –2 –1 0 1

Answer:

1.25 hours  (1 and 1/4 hours)

Step-by-step explanation:

Kiran;s aunt bikes at an average rate of 8 miles/hr.  Assuming it is an average day, we can determine the time it will take her to bike 10 miles by dividng the miles by her average speed:

  (10 miles)/(8 miles/hr)

The miles cancel and the hr comes to the top:

 (10/8) hours or 1.25 hours  1 and 1/4 hours

Kiran's aunt takes 1.25 hours to cover the distance of 10 miles at the average speed of 8 miles per hour.

In unit time, the distance covered by any object is called speed.

In mathematical term, Speed is express as S = D/T,

where S=speed, D=distance, T= time.

Given that,

Distance that Kiran's aunt plans to bike = 10 miles.

The average speed of bike = 8 miles per hour.

To find the time taken by Kiran' aunt to cover 10 miles distance,

Use Formula

Time = Distance / speed

Time = 10 / 8

Time = 1.25

The time taken by Kiran's aunt to cover 10 miles distance is 1.25 hours.

Let the number of miles be x.

Then we have the following equation:

Solve it for x:

The slope and y-intercept of a graph can be determined by examining the equation of the line.

The slope is the coefficient of the x-term (the number next to x in the equation) and the y-intercept is the number that the line crosses the y-axis (the constant in the equation). For example, if the equation of a line is y = 2x + 5, then the slope is 2 and the y-intercept is 5. To graph the line, you can use the slope and y-intercept. Start at the y-intercept and move up or down the number of units indicated by the slope. For example, if the slope is 2, move two units up or two units down and plot a point. Repeat this process until the graph is complete.

68.26% of students out of 500 would score between 68 and 82  if the mean is 75 and standard deviation is 7.

A low standard deviation suggests that values are often close to the mean (also known as the anticipated value) of the collection, whereas a large standard deviation suggests that values are dispersed over a wider range.

Standard deviation, often known as SD, is most frequently represented in mathematical texts and equations by the lower case Greek letter (sigma), for the population standard deviation, or the Latin letter s, for the sample standard deviation.

Given,

Mean μ=75

σ=7

By using normal distribution,

P(68<x<82)=P(((68-μ)/σ)<z<((82-75)/7))

P(-1<z<1)

P(z<1)-P(z< -1)

By using z-table, we get

=0.8413-0.1587

=0.6826

P(68<x<82)=0.6826≈68.26

P(68<x<82)=68.26%

Answer:

If the video game that Ethan bought usually costs $39.99, and it was on sale for 20% off, then the discount on the game would be $39.99 x 20/100 = $8.00. To determine the final price of the game after the discount, we can subtract the discount from the original price of the game, which gives us:

Final price = $39.99 - $8.00 = $31.99

Therefore, Ethan paid $31.99 for the video game that was on sale. This can be rounded to the nearest cent to give us a final answer of:

Final price = $31.99 ≈ $32.00.

Therefore, Ethan paid $32.00 for the video game that was on sale.

Answer:

To solve for the value of x that makes the equation 52(x−2)=4 true, we need to first isolate the x term on one side of the equation. We can do this by dividing both sides of the equation by 52 to get rid of the coefficient in front of the x term.

Dividing both sides of the equation by 52, we get:

52(x−2) = 4

(x−2) = 4/52

(x−2) = 1/13

Next, we can add 2 to both sides of the equation to isolate the x term on the left side of the equation.

(x−2) + 2 = 1/13 + 2

x = 1/13 + 2

x = (1/13) + (2/1)

x = (13+26)/13

x = 39/13

Therefore, the value of x that makes the equation 52(x−2)=4 true is x = 39/13.

The measurement of <B is 121 degree.

The sum of a triangle's three internal angles is 180 degrees, as stated by the angle sum Property of a triangle.

According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees.

Given:

let the measure of <A be x.

So, m<G= x- 9

and, m<B = 4x- 15

Using Angle Sum Property

m<A+ m<B+ m<G= 180

x+ 4x- 15 + x- 9 = 180

6x - 24 = 180

6x = 180+ 24

x= 204/6

x= 34

So, m<A = 34

m<B= 4(34) - 15 = 121

and, m<G = 34 - 9= 25 degree.

Hence, the measure of <B is 121 degree.

In a shipment of 3500 tomatoes can be expected to weight from 0.32 lb to 0.92 lb is 3340. When A vegetable distributor knows that during the month of august, the weights of its tomatoes are normally distributed with a mean Of 0.62 lb and a standard deviation of 0.15.

A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean. The standard deviation measures the degree of dispersion of a set of data. Each data point is compared to the average of all the data points, and standard deviation gives a determined value that indicates whether the data points are clustered together or dispersed. The standard deviation of a normal distribution indicates how far values deviate from the mean.

The solution of the system of equations y = -3x - 2 and 5x + 2y = 15 is (-19, 55)

The first equation is

y = -3x - 2

The second equation is

5x + 2y = 15

To solve this problem we have to use the substitution method

Substitute the value of y = -3x - 2 in the second equation 5x + 2y = 15

5x + 2(-3x -2) = 15

5x - 6x - 4 = 15

-x - 4 = 15

-x = 15 + 4

-x = 19

x = -19

Substitute the value of x in the first equation

y = -3x - 2

y = -3(-19) - 2

= 57 - 2

= 55

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. The equation of a line that is perpendicular to Y = -3x^2 is: X = -3y^2/2

The equation of a line that is perpendicular to a given line is found by changing the sign of the slope of the given line and taking the reciprocal of the slope.

The slope of the given line Y = -3x^2 is -3, so the slope of the line perpendicular to it is 3.

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Therefore, the equation of a line that is perpendicular to Y = -3x^2 is: x = 3y + b

We can now solve for the y-intercept, b, by substituting the point (0,0) into the equation:

x = 3y + b

0 = 3(0) + b

b = 0

The probability that in the resulting coloring, no two adjacent edges have the same color is 1/24.

It is given that the edges of a regular pentagon are colored res, blue or green at random, so that each edge has an equally likely chance of being painted with any color.

So you can't have 0 reds.

You can have 1 red and there are 2 scenarios for that.

You can have 2 reds and there are 8 scenarios for that.

You can't have 3+ reds.

In total there are 10 scenarios that work.

Therefore there are 3⁵ - 3 total cases.

i.e there are 240 total cases.

So the probability that no two adjacent edges have the same color is,
