Point P is located 2/5 of the distance from W to Z. Point W is located at (-5, -2) and point P is located at (1, 4). What are the coordinates of point Z?
The coordinates of point Z is (-5/7, 16/7)
Calculating the midpoint of a line using a ratioThe formula for calculating a coordinate points using the points (-5, -2) and point P is located at (1, 4) in the ratio 2:5 is expressed as:
Z (x, y) = {(ax₁+bx₂)/a+b, (ay₁+by₂)/a+b}
Substitute the coordinates and ratios to have;
Z (x, y) = {(2(-5)+5(1))/2+5, (2(-2)+5(4))/2+5}
Z(x, y) = {-10+5/7, -4+20/7}
Z(x, y) = (-5/7, 16/7)

A car detailing shop charges $30 for materials, plus $50 per hour for labor to paint pinstripes on a car. Which function can be used to find the total cost C(h) to get pinstriping that requires h hours to complete?
The function that can be used to find the total cost C(h) to get pinstriping that requires h hours to complete is; C(h) = 50h + 30
How to create Cost Function?
We are given the following costs in the car detailing shop as follows;
Cost of Materials = $30
Cost per hour for labor = $50
Since the equation of a line in slope intercept form is; y = mx + c, then we can say that the equation here can also be expressed as;
C(h) = 30 + 50h
The function that can be used to find the total cost C(h) to get pinstriping that requires h hours to complete is; C(h) = 30 + 50h

6,3.1,9 can it make a triangle
Yes
Step-by-step explanation:We can tell if a triangle can exist based on the relationship between the side lengths.
Side Length Relationships
For a triangle to really exist, the sum of the smaller legs must be greater than the length of the longest leg. This can be expressed with the inequality a + b > c, where a and b are the shorter legs.
Now, we can plug the values we are given into this inequality.
6 + 3.1 > 99.1 > 9Since the inequality is true, this triangle does exist.
Other Examples
One of the most important things to remember is that the sum of the shorter legs must be greater than, not equal to, the longest leg. So take the sides 4, 6, and 10.
4 + 6 > 1010 > 10This statement is not true. 10 is not greater than 10; they are equal. Thus, these sides cannot make a triangle.
Additionally, if the 3 numbers are Pythagorean triples, then it will be a right triangle. For example, the sides 5, 12, and 13 will create a right triangle.

the population standard deviation for the height of college baseball players is 3.0 inches. if we want to estimate 95% confidence interval for the population mean height of these players with a 0.68 margin of error, how many randomly selected players must be surveyed?
The number of players randomly selected is 381 and the standard deviation is 1.96.
What is the standard deviation?The standard deviation is a measurement of how much a group of values varies or is dispersed. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection. The lower case Greek letter (sigma), for the population standard deviation, or the Latin symbol, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation. Standard deviation may be written as SD. A random variable, sample, statistical population, data set, or probability distribution's standard deviation is equal to the square root of its variance.
[tex]Z(\alpha /2)=1.96[/tex]
Sample size = n = [tex][Z(\alpha /2 * \sigma/E) ]^{2}[/tex]
n = [1.96 * 3.0 / 0.95]²
n = 381.85
n ≈ 381

What does x equals to
The value of x is 20°
According to the question we have been given two parallel lines which is cut by a transversal line. There are total 8 angles and given is the measure of
∠4 = 5x + 35° and ∠7 = 45°.
We need to find the value of x.
Note that when two parallel lines are cut by a transversal then
i) corresponding angles are equal that is
∠1 = ∠5, ∠2 = ∠6, ∠3 = ∠7, and ∠4 = ∠8
ii) alternate interior angles are equal that is
∠3 = ∠6, and ∠4 = ∠5
iii) alternate exterior angles are equal that is
∠1 = ∠8, and ∠2 = ∠7
iv) Consecutive interior angle sum is 180°
∠4 + ∠6 = 180°, and ∠3 + ∠5 = 180°.
Now using these rules we will solve this problem
Because of corresponding angles , ∠3 = ∠7 = 45°
Also ∠3 and ∠8 make a linear pair and sum of linear pair is 180°.
Therefore , ∠3 + ∠8 = 180°
45° + 5x + 35° = 180°
5x = 180° - 80°
x = 20°
Hence the value of x is 20°

What is line?A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
Given:
The equation of the line is
y+4=4(x-2)
We have to find the slope and point on the line.
y+4=4(x-2)
y+4=4x-8
Substract 4 from both sides we get,
y=4x-12
Since the equation now is in y = mx + b form, we can identify the slope m=4 and the y-intercept b=-12 and point on the line origin (0,0).
Therefore, the slope is 4 and point on the line is origin (0,0).

What do we mean by probability?Probability is a branch of mathematics that deals with numerical summaries of how likely an event is to occur or how likely a proposition is to be true. The likelihood of an event occurring is a number between 0 and 1, where 0 indicates the event's impossibility and 1 indicates certainty.To find the probability that at least one of them has been vaccinated:
In a huge number, 63% of people are vaccinated, leaving 37% unvaccinated. The point of concern for the probability that at least one of the four randomly selected people has been vaccinated. As a result, we must account for the possibility that one, two, three, or four randomly selected people were vaccinated.We use P(1) for only one person; the same reasoning should apply to other subscripts.
P(1) = (63/100)(37/100)(37/100)(37/100) = 0.03089833P(2) = (63/100)(63/100)(37/100)(37/100) = 0.05094049P(3) = (63/100)(63/100)(63/100)(37/100) = 0.08398297P(4) = (63/100)(63/100)(63/100)(63/100) = 0.13845841Adding all these probabilities given 0.3042802.
