500 values are normally distributed with a mean of 125 and a standard deviation of 10 which percent of the values lies between 115-125
The percent that the value is between 115 - 125 is 34.13%.
What is defined as the standard normal distribution?A standard normal distribution is a symmetric probability distribution with equal mean, mean, and mode values. The value of the probability of a standard normal distribution is achieved from a statistical table or computer software.For the given question;
The total number of the sample is 500.
The mean of the sample is; μ = 125.
The standard distribution is; σ = 10.
The percentage of the values must lie between 115-125.
Thus,
P(115 < X < 125) = P[(115 - 125)/10 < (x - μ)/ σ < (125 - 125)/10]
= P[-1 < Z < +0]
Z for +0 = 0.50000 and z for -1 = 0.15866 obtained from Z-score table.
P(115 < X < 125) = [0.50000 - 0.15866]
P(115 < X < 125) = 0.34134
P(115 < X < 125) = 34.13%
Therefore, the probability for percent of the values lies between 115-125 is 34.13%.

What is the area of FGH? (Please help it’s due tmrw !! I’ll mark you brainliest)
Answer:
102.0625 square units
Step-by-step explanation:
First determine the length of each side using the distance formula for two points. Then use Heron's formula to determine the area of a triangle given three sides
Distance Formula
The distance between two points is the length of the path connecting them
The distance between points (x₁, y₁) and (x₂, y₂) is given by the Pythagorean theorem:
[tex]d = \sqrt {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}[/tex]
Let's compute the lengths of the sides FH, FG and HG
The three vertices are F(-2, 5) G(7, -10) and H(-9, -6) as indicated on the graph
So length FG between (-2,5) and (7,-10)
[tex]FG= \sqrt {(7 - (-2))^2 + (-10 - 5)^2}[/tex]
[tex]= \sqrt {(9)^2 + (-15)^2}[/tex]
[tex]= \sqrt {{81} + {225}}[/tex]
[tex]= \sqrt {306}[/tex]
FG [tex]= 17.492856[/tex] (round to 17.5)
Length FH between(-2,5) and (-9, -6) is
[tex]FH = \sqrt {(-9 - (-2))^2 + (-6 - 5)^2}[/tex]
[tex]= \sqrt {(-7)^2 + (-11)^2}[/tex]
[tex]= \sqrt {{49} + {121}}[/tex]
[tex]= \sqrt {170}[/tex]
FH [tex]= 13.038405[/tex] (can be rounded to 13.04
Length GH between (7, -10) and (-9, -6) is
[tex]GH = \sqrt {(-9 - 7)^2 + (-6 - (-10))^2}[/tex]
[tex]= \sqrt {(-16)^2 + (4)^2}[/tex]
[tex]= \sqrt {{256} + {16}}[/tex]
[tex]= \sqrt {272}[/tex]
GH [tex]= 16.492423[/tex] (can be rounded to 16.5)
Determining the area of a triangle given 3 sides
Heron's formula allows us to find the area of a triangle given 3 sides If the sides are a, b and c the general form of Heron's formula is
[tex]Area = \sqrt {s(s-a)(s-b)(s-c)}[/tex]
where s is the semi-perimeter = [tex]\frac{a+b+c}{2}[/tex]
Substituting values we get
s = [tex]\frac{17.5+13.04+16.5}{2} = 23.52[/tex]
[tex]Area = \sqrt {23.52(23.52-17.5)(23.52-13.04)(23.52-16.5)}[/tex]
[tex]= \sqrt{23.52\cdot6.02\cdot10.48\cdot7.02}[/tex]

Point W is the midpoint of Segment VY. VW=9x + 7 and WY = 16x - 28. Find VY.
since W is the midpoint, that simply means that both halves are twins, so
[tex]V\stackrel{9x+7}{\rule[0.35em]{10em}{0.25pt}} W\stackrel{16x - 28}{\rule[0.35em]{10em}{0.25pt}} Y \\\\\\ \stackrel{VW}{9x+7}~~ = ~~\stackrel{WY}{16x-28}\implies 7=7x-28\implies 35=7x\implies \cfrac{35}{7}=x \\\\\\ \boxed{5=x}\hspace{5em}\stackrel{VW}{9(5)+7\implies 52}\hspace{5em}\underset{52~~ + ~~52}{\stackrel{\textit{\LARGE VY}}{104}}[/tex]
The length of segment VY, represented by "a," is 25x - 21.
How to find the length of the segmentTo find the length of segment VY, we can use the fact that W is the midpoint of VY. The midpoint of a line segment divides it into two equal parts. Therefore, the length of VW plus the length of WY equals the length of VY.
Let VY be represented by "a." Then, according to the midpoint property:
VW + WY = VY
Substitute the given expressions for VW and WY:
(9x + 7) + (16x - 28) = a
Now, combine like terms:
25x - 21 = a
So, the length of segment VY, represented by "a," is 25x - 21.

What is the equation of the tangent of f(x) 3 X at (1, 3)?
The Equation of the tangent line is y = 4x - 1.
According to the statement
We have to find that the equation of the tangent of the line.
So, For this purpose, we know that the
Equation of the tangent line can be found using the formula y – y1 = m (x – x1), where m is the slope and (x1, y1) is the coordinate points of the line.
From the given information:
f(x) = 3 X at (1, 3)
Then
The tangent line of a curve y = f(x) is a line that touches the curve at a point (x0, y0). Its slope (m) is found by substituting the point where it is drawn in the derivative f'(x) and its equation is found by using y - y0 = m (x - x0).
From the given it is clear that the slope of the equation is a 3.
Then m = 3
then
y – y1 = m (x – x1)
Substitute the points here
y - 3 = 4(x - 1)
Then
y = 4x - 4 +3
y = 4x - 1.
So, The Equation of the tangent line is y = 4x - 1.

You have quarters, nickels,
and dimes that total $1.85. You have twice as many
nickels as dimes, and 2 more quarters than dimes.
How many of each coin do you have?
The number of dimes that we have are 3, the number of nickels are 6 and the number of quarters are 5.
Let the number of dimes be x.
So, we get that:
The number of quarters will be = x + 2
The number of nickels will be = 2 x
Now, 1 dime = $0.10.
1 nickel = $ 0.05
1 quarter = $ 0.25
Amount of dimes = 0.10 x
Amount of nickels = 0.10 x
Amount of quarters = 0.25 x + 0.5
Total amount of coins = $ 1.85
So, we get the equation as:
0.10 x + 0.10 x + 0.25 x + 0.5 = 1.85
0.45 x = 1.35
x = 135 / 45
x = 3
Dimes = 3
Nickels = 6
Quarters = 5
Therefore, we get that, the number of dimes that we have are 3, the number of nickels are 6 and the number of quarters are 5.

What is deductive reasoning?Deductive reasoning can be defined as a type of logical reasoning that typically involves drawing conclusions based on a given set of rules and conditions, or from one or more premises (factual statements) that are assumed to be generally (universally) true.
What is an inference?An inference can be defined as a process through which a reader can logically deduce the meaning or message (information) that is associated with a literary work, especially through induction.
Since "Happy Graduation, Julie." and "Names/Nombres," were inscribed on the gift, it ultimately implies that the people at the store were obviously of English speaking heritage, rather than Spanish (Julia’s heritage).

The short-run production function of the Auto parts firm is given by Q (L)=5L-L2, where Q is the units of output and L is the number of labor hours. Recall that “marginal product of labor” is the change in the total product as we change the amount of hired labor. Please calculate the marginal product of labor.
Hint: Use the concept of first derivative.
I am sure that I am not calculate it correcctly, as I am getting L = 5 and Q = 0 when calculated using first derivative.
Please provide a detailed answer.
Thank you.
Using derivatives, the equation for the marginal product of labor is given by:
Q'(L) = 5 - 2L.
What is the marginal product equation?As stated in the problem, the “marginal product of labor” is the change in the total product as we change the amount of hired labor, hence it is given by the derivative of the production as a function of labor.
For this problem, the production function is given by:
Q(L) = 5L - L².
Hence the marginal product of labor is given by:
Q'(L) = 5 - 2L.
