A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. If y=2x+7 is changed to y=(1/2)x+7, the slope of the equation will change from 2 to 0.5.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is constant or the y-intercept.
If y=2x+7 is changed to y=1/2x + 7. Then the slope of the function equation will be changed, while the y-intercept will remain the same.
Hence, If y=2x+7 is changed to y=(1/2)x+7, the slope of the equation will change from 2 to 0.5.

Make u the subject of formula in
M=m(v-u).u
Answer:
u = v - 1
Step-by-step explanation:
I'm guessing the formula you've given me is m = m(v - u), and I'm going to solve it that way. If it's actually different, let me know so I can redo the answer! :)
So, we have the equation m = m(v - u) and we're trying to make u the subject, or isolate it on one side of the equation. Right now, it's being subtracted from v and then multiplied by m. Let's start by dividing both sides of the equation by m so we can stop multiplying (v - u) by m.
m = m(v - u)
m/m = m(v-u)/m
1 = v - u
Now, our equation is pretty simple, but our u is still being subtracted from v, so we should add a u to both sides.
1 = v - u
1 + u = v - u + u
1 + u = v
Now, we're adding 1 to u, so let's go ahead and subtract 1 from both sides.
1 + u = v
1 - 1 + u = v - 1
u = v - 1
And we now we have u as the subject of our formula.

To determine her breathing rate, Miranda divides up her day into three parts: morning, afternoon, and evening. She then measures her breathing rate at 4 randomly selected times during each part of the day. What type of sampling is used? A. Simple random B, Stratified C. Systematic D. Convenience E. Cluster
The type of sampling used in this scenario is B. Stratified sampling. Stratified sampling involves dividing the population into distinct subgroups or strata and then selecting samples from each subgroup.
In this case, Miranda divides her day into three parts: morning, afternoon, and evening. Each part of the day represents a stratum or subgroup. Miranda measures her breathing rate at 4 randomly selected times during each part of the day. This means she is taking samples from each of the three strata (morning, afternoon, and evening) and collecting data from within those subgroups.
By using stratified sampling, Miranda ensures that her samples represent the different parts of her day in a proportional and systematic manner, allowing her to capture potential variations in her breathing rate throughout the day.

3x = 30
divide both sides by 3
x = 30/3
x = 10

The number of edges that the prism has is
n + 2What does a prism's cross section look like?When a plane intersects a prism, the shape formed is known as the cross section. The cross section of the prism will have the same form as the base if it is divided by a plane that runs horizontally and parallel to the base.
A prism is a 3-dimensional object with two congruent and parallel bases (which are polyggonal) connected by rectangular lateral faces. The number of edges of a prism is equal to the sum of the number of edges of the two bases and the number of lateral faces.
Each base of the prism has n edges, so the two bases together have 2n edges. The number of lateral faces of the prism is equal to the number of edges of one of its bases, so there are n lateral faces. Each lateral face has 4 edges, so the total number of edges of the lateral faces is 4n.
Therefore, the total number of edges of the prism is equal to the sum of the number of edges of the two bases (2n) and the number of lateral faces (4n), which is 2n + 4n = 6n.
In conclusion, the cross section of a prism is an n-sided polygon and the prism has n + 2 edges.

The population growth rate (r) for 2009 in the tiny country of fremont is found as 1.4.
Describe the term population growth rate (r)?The population growth rate (r) shows how fast a population ages over time. A population is growing if the growth rate is positive. A negative growth rate signals a declining trend. A birth rate (b) and mortality rate are the two primary elements that influence population increase (d). People leaving the population to move to another territory or immigrating from a different region may also have a consequence on population increase (emigration, e).All these elements are taken into account when formulating the population growth formula.
r = [(b + i) - (d + e)]/1000
r = population growth rateb = birth rate; 2,000i = immigration rate; 100d = death rate; 500e = emigration rate; 200Put the values in the formula.
r = [(2,000 + 100) - (500 + 200)]/1000

a bag contains 3 red balls and 2 blue balls. you draw a ball at random, then without replacing it, draw another ball. what is the probability that the first ball is red and the second ball is blue?
The probability of drawing a red ball on the first draw is 3/5. Since the ball is not replaced, there are now 4 balls left in the bag, with 2 blue balls. Thus, the probability of drawing a blue ball on the second draw is 2/4 or 1/2. Therefore, the probability of drawing a red ball on the first draw and a blue ball on the second draw is (3/5) * (1/2) = 3/10.
To calculate the probability of drawing a red ball on the first draw and a blue ball on the second draw, we use the multiplication rule of probability. According to this rule, the probability of two events A and B occurring is the product of the probabilities of each individual event.
Here, event A is drawing a red ball on the first draw, which has a probability of 3/5 since there are 3 red balls out of 5 total balls in the bag. Since the ball is not replaced after the first draw, event B is drawing a blue ball on the second draw from the remaining 4 balls. There are 2 blue balls out of 4 total balls left in the bag, so the probability of drawing a blue ball on the second draw given that a red ball was drawn on the first draw is 2/4 or 1/2.
Thus, the probability of drawing a red ball on the first draw and a blue ball on the second draw is (3/5) * (1/2) = 3/10. Therefore, the probability of drawing a red ball on the first draw and a blue ball on the second draw is 3/10.

The probability that a randomly selected Manhattan resident spends New Year's Eve at Times Square, given that the resident is out of town on New Year's Eve, is 0.
Determine the probability?If the resident is out of town on New Year's Eve, it implies that they are not present in Manhattan during that time. Therefore, it is not possible for them to spend New Year's Eve at Times Square if they are not in town.
Since the resident is out of town, the probability of them being at Times Square on New Year's Eve is zero. Probability is a measure of the likelihood of an event occurring, ranging from 0 (impossible) to 1 (certain). In this case, the event of a resident being at Times Square on New Year's Eve is impossible because they are out of town.
Hence, the probability of a randomly selected Manhattan resident spending New Year's Eve at Times Square, given that they are out of town on New Year's Eve, is 0.

Look at the intersection of madison street and peachtree street. describe the angles on the north side of the intersection as either supplementary or complementary explain your reasoning.
The angles on the north side of the intersection are complementary angles because complementary angles are two angles whose measures add up to 90 degrees. At the intersection of Madison Street and Peachtree Street, the north side of the intersection forms a right angle (90 degrees).
Any angle on the north side of the intersection must be complementary to the right angle, meaning its measure must be less than 90 degrees.
For example, if we consider the angle formed by Madison Street and the north side of the intersection, it is less than 90 degrees and therefore complementary to the right angle formed by the intersection. Similarly, if we consider the angle formed by Peachtree Street and the north side of the intersection, it is also less than 90 degrees and complementary to the right angle formed by the intersection.
Therefore, all angles on the north side of the intersection are complementary to the right angle formed by the intersection.

Find the geometric mean between pair of numbers.
3√5/4 and 5√5/4
The geometric mean of 3√5/4 and 5√5/4 is 5√3/4.
Geometric mean, like arithmetic mean, is a kind of average and a measure of central tendency.
To solve for the geometric mean, we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. In other words, geometric mean is the nth root of the product of n values.
The formula for the geometric mean is given by:
GM = n√x1 x2 . . . xn
Solving for the geometric mean between 3√5/4 and 5√5/4 using the formula:
GM = n√x1 x2 . . . xn
where n = 2, x1 = 3√5/4, and x2 = 5√5/4
GM = √(3√5/4)(5√5/4)
GM = √(75/16)
GM = 5√3/4
Hence, the geometric mean of 3√5/4 and 5√5/4 is 5√3/4.
