The required probability of the temperature of a person which has normal distribution is given by 0.9500.
Temperature of a person follows a normal distribution.
Use the Empirical Rule to estimate the probability.
Temperature of a randomly selected person will be within 2.42 standard deviations of its mean.
Empirical Rule states that for a normal distribution is,
About 68% of the data falls within one standard deviation of the mean.
About 95% of the data falls within two standard deviations of the mean.
About 99.7% of the data falls within three standard deviations of the mean.
Probability of temperature of a randomly selected person within 2.42 standard deviations of its mean = 95%
95%
= 95/100
= 0.95
=0.9500 ( round this to four decimal places )
Therefore, the probability that the temperature of a randomly selected person is 0.9500.

Aiden estimates that the length of a piece of rope is 8. 5 inches. If it’s actual length is 7. 1 inches , what is the percent error of Aidens estimate ? Round to the nearest tenth if necessary
Aiden's estimated the length of a piece of rope as 8.5 inches, while its actual length is 7.1 inches. Therefore, the percent error of Aiden's estimate is 11.3%.
To calculate the percent error, you first need to find the difference between the actual length and the estimated length. Subtract 7.1 inches from 8.5 inches and you get 1.4 inches. This is the difference between the two lengths.
Next, divide the difference by the actual length and multiply by 100. The equation is: (difference/actual length) * 100. So, (1.4/7.1)*100 = 11.3%. Therefore, the percent error of Aiden's estimate is 11.3%.
It is important to be accurate when making measurements and estimates. A small difference in numbers can lead to a large error in the final result. Knowing the percent error can help you to improve your measurements and estimates and achieve greater accuracy.

The zeros of the polynomial function f(x) are 3, -[(2 -i√2) / 3] and -[(2 + i√2) / 3]
What is the zero of the functionTo find the zeros of the polynomial function f(x), we need to find the values of x for which f(x) = 0.
We can start by factoring out a common factor of 3x^2 from the polynomial:
f(x) = 3x^3 - 5x^2 - 10x - 6
f(x) = 3x^2(x - 5/3) - 2(5x + 3)
Now, we can set each factor equal to zero and solve for x:
3x^2(x - 5/3) - 2(5x + 3) = 0
3x^3 - 5x^2 - 10x - 6 = 0

For which values of x is the expression undefined?

x² - 16
Answer:
x = - 4 , x = 4
Step-by-step explanation:
the expression is undefined if the denominator equals zero
equate the denominator to zero and solve for x
x² - 16 = 0 ( add 16 to both sides )
x² = 16 ( take square root of both sides )
x = ± [tex]\sqrt{16}[/tex] = ± 4

The height of a triangle is 3 inches less than twice the length of its base. If the total area of the triangle is 7 square inches, find the length of the base and height.
Answer:
Let x be the length of the base of the triangle, then the height h is given by h = 2x - 3 (since the height is 3 inches less than twice the length of the base).
The area of a triangle is given by the formula A = (1/2)bh, where b is the base and h is the height. We are given that the total area of the triangle is 7 square inches, so we can write:
(1/2)(x)(2x - 3) = 7
Multiplying both sides by 2 to eliminate the fraction, we get:
x(2x - 3) = 14
Expanding the left side, we get:
2x^2 - 3x = 14
Subtracting 14 from both sides, we get:
2x^2 - 3x - 14 = 0
We can now use the quadratic formula to solve for x:
x = (-b ± sqrt(b^2 - 4ac))/(2a)
where a = 2, b = -3, and c = -14. Plugging in these values, we get:
x = (-(-3) ± sqrt((-3)^2 - 4(2)(-14)))/(2(2))
= (3 ± sqrt(169))/4
= (3 ± 13)/4
Taking the positive value for x (since the length of the base must be positive), we get:
x = (3 + 13)/4
= 4
Therefore, the length of the base is 4 inches. To find the height h, we can use the formula h = 2x - 3:
h = 2(4) - 3
= 5
So the height of the triangle is 5 inches.
Baseball pitcher is employing a ballistic pendulum to determine the speed of his fastball. A 3. 3-kg lump of clay is suspended from a cord 2. 0 m long. When the pitcher throws his fastball aimed directly at the clay, the ball suddenly becomes embedded in the clay and the two swing up to a maximum height of 0. 080 m. If the mass f the baseball is 0. 21 kg, find the speed of the pitched ball
The solution to the given problem of speed comes out to be v=21.12m/s.
How quickly something is moving is measured by its speed at a distance. How far an object moves in one unit of time is determined by its speed. Speed is calculated as follows: speed = distance * time. The most widely used speed measurement units are meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph) (mph).
Here,
Given : A 2.0 m long cord is supporting a 3.3 kg lump of clay.
Two swing up to an absolute maximum of 0.080 meters
Ball and clay's subsequent impact velocity
=>√(2*10*0.08)=1.264m/s
To find the velocity of the ball before collision
0.21*v=(3.3+0.21)*1.264
v=21.12m/s
Therefore, the solution to the given problem of speed comes out to be v=21.12m/s.

true or false: when dealing with fixed effects, a de-meaned model approach is superior to the lsdv approach because the de-meaned model gives us more accurate coefficient estimates.
The statement that "when dealing with fixed effects, a de-meaned model approach is superior to the lsdv approach because the de-meaned model gives us more accurate coefficient estimates" is true.
Fixed effects are a type of regression technique used to understand the effect of a single variable across different groups (such as across countries, across states, across individuals, etc.) by comparing the variance of the variable within each group to the variance of the variable across all groups.
When conducting a fixed effects regression, researchers must choose between the least squares dummy variable (LSDV) and de-meaned model approaches.Both models produce unbiased estimates of the coefficients, but the LSDV model has an advantage in that it provides more flexibility when dealing with interactions between fixed effects and time-varying covariates. On the other hand, the de-meaned model is preferred for reasons of computational efficiency and it can handle certain types of data that the LSDV model cannot (such as panel data with a small number of time periods).

Parker is wrong, as the volume of the cube container is obtained as [tex]\frac{1}{512} t^9u^{12}[/tex].
What is volume?
Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
The volume of a cube is given by the formula V = s³, where s is the length of one side of the cube.
In this case, the length of the container is given as [tex]\frac{1}{8} t^3u^4[/tex].
To find the volume of the cube, we need to cube this length -
[tex]V=\big(\frac{1}{8} t^3u^4\big)^3[/tex]
Simplifying this expression using the rules of exponents, we get -
[tex]V=\big(\frac{1}{8}\big)^3 \times (t^3)^3 \times (u^4)^3[/tex]
[tex]V =\frac{1}{512} t^9u^{12}[/tex]
So, the actual volume of the container is [tex]\frac{1}{512} t^9u^{12}[/tex], not [tex]\frac{1}{12} t^9u^{12}[/tex] as Parker said.

Measure of ∠1 = 126 deg, Measure of ∠4 = 54 deg, and measure of ∠7 = 126 deg.
∵ Lines p and q are parallel, and t is transversal,
∴ ∠3 and ∠7 form pair of corresponding angles,
⇒ ∠3 and ∠7 are equal
∴∠7=126 deg.
Also, ∠3 and ∠1 are vertically opposite angles,
∴ ∠3 and ∠1 are equal.
⇒ ∠1=126
Again, as t is a straight line and line p intersects it,
∴ ∠3 and ∠4 form linear pair.
⇒ ∠3 and ∠4 are complementary.
⇒ ∠3+∠4=180
⇒ ∠4+126=180

the height VO of the rectangular pyramid VPQRS is 5 cm.
WHAT IS RECTANGULAR PYRAMID?
A rectangular pyramid is a type of pyramid where the base is a rectangle and the lateral faces are triangles with a common vertex (apex) that is not in the plane of the base. It is a polyhedron with a rectangular base and triangular faces that meet at a single vertex. The height of the pyramid is the perpendicular distance from the apex to the base. The volume of a rectangular pyramid can be calculated using the formula:
V = (1/3) * base area * height
where base area is the area of the rectangular base and height is the perpendicular distance from the apex to the base.
To find the height VO of the rectangular pyramid VPQRS, we can use the formula for the volume of a pyramid:
V = (1/3) * base area * height
where base area is the area of the rectangle formed by the base of the pyramid, and height is the height of the pyramid.
We are given that the volume of the pyramid is 100 cm³. We can also find the base area by multiplying the length PQ by the width QR:
base area = PQ * QR = 10 cm * 6 cm = 60 cm²
Substituting these values into the formula for the volume of a pyramid, we get:
100 cm³ = (1/3) * 60 cm² * height
Simplifying, we get:
height = (100 cm³ * 3) / (60 cm²)
height = 5 cm
Therefore, the height VO of the rectangular pyramid VPQRS is 5 cm.

What is the x-axis scale?The horizontal scale used in a graph is called the X axis. Measurements on the coordinate plane are made using it as a reference line. The position of an object on that plane is described by its distance from the x and y axes.
What is the data's X and Y axis scale?All potential data that can be graphed is represented by the numbers on the X and Y axes. Each number here is different by ten. Scale is the name for this. On a coordinate grid, scale is the distance between each square.

Write an equation in slope-intercept form of the line with the given characteristics
perpendicular to y=-3x+1; passes through (2,2)
Answer:
The equation in slope-intercept form of the line perpendicular to y = -3x + 1 and passing through (2, 2) is y = (1/3)x + 4/3.
Step-by-step explanation:
To find the equation of the line perpendicular to y = -3x + 1 and passing through the point (2, 2), we first need to determine the slope of the line we are looking for.
The slope of any line perpendicular to y = -3x + 1 will be the negative reciprocal of the slope of y = -3x + 1. The slope of y = -3x + 1 is -3, so the slope of the line we want is the negative reciprocal of -3, which is 1/3.
So the slope of the line we want is 1/3. We also know that the line passes through the point (2, 2). We can now use the point-slope form of the equation of a line to find the equation of the line we want:
y - y1 = m(x - x1)
where m is the slope of the line, and (x1, y1) is the point the line passes through.
Substituting m = 1/3, x1 = 2, and y1 = 2, we get:
y - 2 = (1/3)(x - 2)
Multiplying both sides by 3, we get:
3y - 6 = x - 2
Subtracting x from both sides, we get:
-x + 3y = 4
So the equation of the line perpendicular to y = -3x + 1 and passing through the point (2, 2) is -x + 3y = 4, which is in standard form. We can also write it in slope-intercept form:
3y = x + 4
y = (1/3)x + 4/3
So the equation of the line we want in slope-intercept form is y = (1/3)x + 4/3.
