The new coordinates of the point will be (2, -3).

Coordinate is a system used to determine the exact location of a point on a 2-dimensional plane or 3-dimensional space. It is typically used to pinpoint a specific spot on a map or graph. Coordinate systems are usually written in two or three numbers, representing the x, y and z positions of the point. These coordinates can then be used to calculate distances, angles and other measurements.

After the transformation D5 o R270-, the image point of (-3, 4) will be (2, -3). The transformation D5 is a dilation, which changes the distance between the origin and the point by a factor of 5. The transformation R270- is a rotation by 270 degrees counter-clockwise, which moves the point to the left and up by the same distance. Therefore, the new coordinates of the point will be (2, -3).

This cannot be determined with the information given. To calculate the sample size, we would need to know the population means, the population standard deviation, and the confidence interval.

The confidence interval is 97%, which is the likelihood that the mean of the receipts is less than $38. We can use this information to calculate the margin of error and then use this to calculate the sample size.   The margin of error is calculated by taking the critical value (in this case, 1.96) and multiplying it by the standard deviation of the population. We then divide this by the square root of the sample size to get the margin of error.  

Once we have the margin of error, we can then calculate the sample size by taking the population means minus the margin of error and dividing this by the desired confidence interval. In this case, the desired confidence interval is 97%.   Therefore, without the population means, standard deviation, and confidence interval, it is impossible to calculate the sample size.

For the slope of -3, the altitude where the average temperature is -50°C is 70 km.

What is slope?

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

At 50 kilometer from earth's surface, the temperature is 10°C.

At 80 kilometer from earth's surface, the temperature is -80°C.

The given temperature for unknown altitude is -50°C.

We are told that the temperature varies linearly with altitude, so if y represents the temperature (in °C) and x represents altitude (in km), these variables are related by the equation y = mx + b, where m (the slope) and  b (the y-intercept) are constants.

The two points on this line are (50 km , 10°C) and  (80 km , -80°C).

Use these points to find the slope m -

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

m = (-80 - 10)/(80 - 50)

m = -90/30

m = -3

Recall that the slope of a linear relationship is the "unit rate of change". In other words, the slope of -3 means that the temperature declines by 3°C for every 1 km of additional altitude.

Since the altitude at which the temperature is -50°C is needed, the value of x such that (x, -50°C) is on this line is needed. To find x, simply use the slope formula again, using either of the other two points:

Slope formula using (50,10) and (x,-50) -

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

-3 = (-50 - 10)/(x - 50)

-3(x - 50) = -60

-3x + 150 = -60

-3x = -60 - 150

-3x = -210

x = -210/-3

x = 70

Therefore, the altitude will be 70 km.

the z-value for an apple that weighs 140 grams is 1.5.

The z-value is used to determine how many standard deviations an observation is from the mean of a normal distribution. To find the z-value for an apple that weighs 140 grams, we need to calculate the difference between the apple's weight and the mean weight, and divide by the standard deviation.

Given that the average weight of a honeycrisp apple is 110 grams and the standard deviation is 20 grams, we can calculate the z-value as follows:

(140 - 110) / 20 = 1.5

This means that the apple that weighs 140 grams is 1.5 standard deviations above the mean weight of 110 grams. This information can be used to calculate the probability of finding an apple with a weight of 140 grams. For example, if we use a standard normal distribution table, we can find that the probability of finding an apple with a weight greater than 140 grams is 0.0668, or 6.68%.

What is plane ?

A plane is a Euclidean, two-dimensional surface that extends indefinitely. A plane is the two-dimensional analogue of a point, a line and three-dimensional space.

The normal vector is given by the coefficients of x, y, and z in the equation of the plane:

n = <3, -7, 5>

Next, we need to find a point on the line and a direction vector for the line. The point on the line is (2, 4, 5) and the direction vector can be found by taking the cross product of the normal vector and an arbitrary vector not parallel to the normal vector.

An arbitrary vector not parallel to the normal vector could be <1, 0, 0>. Taking the cross product, we get:

d = n x <1, 0, 0> = <0, 5, -3>

So, the line through (2, 4, 5) perpendicular to the plane 3x - 7y + 5z = 21 is given by:

r(t) = <2, 4, 5> + t<0, 5, -3> = <2 + 0t, 4 + 5t, 5 - 3t>

Answer:

The area of a trapezium with parallel sides of length 19 cm and 21 cm, and a distance of 14 cm between them, is 280 square cm.

Step-by-step explanation:

After 30 minutes, the amount of salt remaining in the tank is 18.75 kg. This is because the brine entering the tank contains 0.03 kg of salt per liter of water, and 25 liters of brine are entering the tank every minute.

Thus, in 30 minutes, 750 liters of brine will have entered the tank, bringing with it 22.5 kg of salt. Since the tank initially contained 20 kg of salt, the amount of salt remaining after 30 minutes is 18.75 kg.

The theory behind the amount of salt remaining in the tank after a given amount of time is based on the idea that the amount of salt entering the tank is equal to the amount of salt leaving the tank. The amount of salt entering the tank is determined by the concentration of salt in the brine solution and the rate at which the brine enters the tank. The amount of salt leaving the tank is determined by the same rate at which the brine enters the tank.
