The value of k from the equation is k = -20

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = kx   be equation (1)

Let the first point be P ( 4 , -80 )

Substituting the values in the equation , we get

The thirty-fourth term of the arithmetic sequence is the thirty-second term plus the common difference, which is not equal to 0.

The thirty-fourth term of the arithmetic sequence is calculated by adding the common difference to the thirty-second term. The common difference is the amount by which each successive term increases or decreases. As the common difference is not equal to 0, the thirty-fourth term is not the same as the tenth or second terms. The second, tenth, and thirty-fourth terms form a geometric sequence, which means that the ratio between any two successive terms is always the same. This ratio is determined by the common difference of the arithmetic sequence, and the thirty-fourth term can be calculated by adding the common difference to the thirty-second term.

165 tiles are needed to cover the entire floor of the room.

First, we need to find out the area of the room in square feet. We do this by multiplying the length and width of the room:

12 feet x 15 feet = 180 square feet

Next, we need to find out the area of one tile in square feet. We do this by squaring the length of one side of the tile:

11 3/11 feet x 11 3/11 feet = 128/121 square feet

Now, we can divide the total area of the room by the area of one tile to find out how many tiles are needed:

180 square feet / (128/121 square feet) = 180 x 121/128 = 165 tiles

So, 165 tiles are needed to cover the entire floor of the room.

The distance will be 1.1319 × 10⁻¹ meters .

Speed of the sound = 3.43 x 10² meters per second

Time to calculate the distance traveled = 3.3 x 10-5 seconds

Since,

Distance = Speed x Time

Using the values we get:

Distance = 3.43 x 10² * 3.3 x 10-5

Distance = 11.319 × 10⁻³ meters

Since the calculators show the final answer is scientific notation, the above answer in scientific notation would be:

An exponential random variable has a probability density function given by:

Thus, the mean and the standard deviation of an exponential random variable are not equal, and they have different values depending on the value of [tex]$\lambda$[/tex]

It is important to note that exponential random variables have a memoryless property, which means that the future behavior of an exponential random variable is independent of its past values.

Step-by-step explanation:

We know

A company’s stock opened at 68 3/8 dollars per share

68 3/8 = 547/8

The stock dropped 1 7/8 dollars on Monday

1 7/8 = 15/8

547/8 - 15/8 = 532/8

The stock dropped another 2 1/2 dollars on Tuesday.

2 1/2 = 5/2

532/8 - 5/2 = 532/8 - 20/8 = 512/8

On Wednesday, the stock gained back 4 1/4 dollars.

4 1/4 = 17/4

512/8 + 17/4 = 512/8 + 34/8 = 546/8

The model on the fifth row has a diameter of 32.5 meters, hence the actual diameter is 32.55 = <<32.55=162.5>>162.5 meters.

The minimal number of coordinates required to specify each point within a mathematical space (or object) is known as the dimension in physics and mathematics.

Because only one coordinate is required to identify a point on a line, such as a point at 5 on a number line, a line is said to have one dimension (1D).

Because two coordinates are necessary to identify a point on a surface, such as the perimeter of a sphere or cylinder, it is referred to as having a dimension of two (2D).

For instance, a point on the surface of a sphere requires both a latitude and a longitude to be located.

So, we can use a scale of 2:5 as a conversion factor to identify the table's missing dimensions.

For instance, the model's length in the second row is 2 inches, but the real length is 5 inches.

This implies that the model's 1 inch corresponds to the actual object's 5 inches.

The actual depth is 10 5 = 50 km because the model's depth is 10 km.

Since the model's length is not specified in the fourth row, we are unable to determine its true length.

Therefore, the model on the fifth row has a diameter of 32.5 meters, hence the actual diameter is 32.55 = <<32.55=162.5>>162.5 meters.

Step-by-step explanation:

x = speed of the passenger train

x - 15 = speed of the freight train

remember, the passenger train is traveling 15 mph faster than the freight train. that also means the freight train travels 15 mph slower than the passenger train.

we could define the variable also the other way around (x = freight train, x + 15 = passenger train).

speed = distance/time period

distance = speed × time period

so,

x×4 + (x - 15)×4 = 260

because when both trains meet somewhere in the middle, it means that the sum of both of their ways traveled is the whole distance between both cities : 260 miles.

4x + 4x - 60 = 260

8x = 320

x = 320/8 = 40 mph

so, the passenger train traveled at 40 mph.

the freight train traveled at 40-15 = 25 mph.

Step-by-step explanation:

When a ball is droped from 2m heights and rises by 75%, then the height of ball after forth bounce is equals to 0.632 meters.

If an object is thrown from high and has a bouncing feature, each bouncing is less than the initial height until it stops. Each bounce reduces the growth rate until it reaches zero. In order to calculate the height of each bounce, so we can estimate what percentage the object will reach after each bounce. If we get the percentage of each bounce, we can easily determine the height of each bounce. We have, a ball is droped from 2 meters and bounce up to 75%. That is height of first bounce is determined by using percentage, height is 2 m × 75% = 2 m×0.75 = 1.5 m

In second bounce, height is 1.5 m × 75%

= 1.5 m×0.75 = 1.12 m

In third bounce, 1.12 m× 75%

= 1.12 m×0.75 = 0.843 m

In forth bounce, height is 0.843× 75%

= 0.843× 0.75 = 0.632 m

The height the ball reaches on its forth bounce is 0.632 m.

The 98% confidence interval to estimate the true cost of a gallon of milk is $2.73 to $3.23.

The standard error is a measure of the variability or spread of a set of sample values. In statistics, the standard error is used to quantify the precision of an estimate of a population parameter, such as the mean or standard deviation. It is calculated as the standard deviation of the sampling distribution of a statistic, usually the mean. The standard error is a useful measure because it provides a way to compare different estimates of a population parameter, and it can be used to construct confidence intervals, which provide a range of values within which the true population parameter is likely to lie with a specified degree of confidence.

The 98% confidence interval to estimate the true cost of a gallon of milk can be calculated using the following formula:

CI = (sample mean) ± (critical value) * (standard error)

Where critical value can be obtained from a standard normal distribution table, corresponding to a given level of confidence.

For 98% confidence, the critical value is 2.33.

CI = $2.98 ± 2.33 * $0.10 = $2.98 ± $0.23 = $2.73 to $3.23

Therefore, the 98% confidence interval to estimate the true cost of a gallon of milk is $2.73 to $3.23

In this problem, we have to apply the Pythagorean theorem to find the lenght of DF line.

a² + b² = c²

7² + b² = 8²

49 + b² = 64

b² = 15

b = 3.87

In this problem, we have to apply the Pythagorean theorem to find the lenght of XF line.

a² + b² = c²

3² + 3.87² = c²

9 + 14.97 = c²

23.97 = c²

4.89 = c

According to the information of the graph we can conclude that the point 2cm from E is on the line EX, and it is located 2cm from E and 5cm from X.

The percentage of Japanese-Americans under 35 in Santa Clara County, CA is approximately 11.3%.

Santa Clara County, CA is home to approximately 27,873 Japanese-Americans. To determine what percentage of this population is under age 35, it is necessary to first calculate the total number of Japanese-Americans under 35. To do this, we can subtract the estimated number of Japanese-Americans over age 35 from the total population of Japanese-Americans. We can then divide this number by the total population of Japanese-Americans to find the percentage of Japanese-Americans under age 35. In Santa Clara County, CA, the estimated number of Japanese-Americans over age 35 is 24,672, and the total population of Japanese-Americans is 27,873. Subtracting 24,672 from 27,873 yields 3,201 Japanese-Americans under age 35. We can then divide 3,201 by 27,873 to get a percentage of 11.3%. Therefore, approximately 11.3% of the Japanese-American population in Santa Clara County, CA is under age 35.
