Answer:
Z = 1.25
Step-by-step explanation:
[tex]\displaystyle Z=\frac{\text{Observed Value}-\text{Mean of the Sample}}{\text{Standard Deviation of the Sample}}\\\\Z=\frac{x-\mu}{\sigma}\\ \\Z=\frac{87-82}{4}\\ \\Z=\frac{5}{4}\\ \\Z=1.25[/tex]
Hence, Michael's z-score is 1.25, which means that he scored 1.25 standard deviations above the class average.

Step-by-step explanation:
Answer
Given
Area = 576 square feet
dimensions of x feet by x feet
Since both the length and width are the same dimensions, x feet, use the area to calculate the length of the dimension.
×·×=576
[tex]x^{2} = 576\\[/tex]
[tex]\sqrt{x^{2}[/tex] = [tex]\sqrt{576[/tex]
×= 24
Now we have the length of the dimension of the fence, normally, we will be using the four sides to build the fence, but since we will be using the wall of the house as one of the sides, then we will only multiply by 3
3x24=72
Therefore, the fencing needed is 72 feet.

By applying trigonometric reasons, Pythagorean theorem and the definition of circle arc, the measure of the arc ADC is approximately 15.858 centimeters.
How to determine the arc of a system formed by a circle and two symmetrical right triangles
Since AB and BC are tangent to the circle, then the triangles OAB and OBC are right angled. We can determine the measure of the angle AOC by using the following inverse trigonometric reason and Pythagorean theorem:
[tex]\theta = 2\cdot \tan^{-1}\left(\frac{\sqrt{10^{2}-4^{2}}}{4} \right)[/tex]
θ ≈ 132.844°
And the measure of the arc ADC is found by the formula for the length of a circle arc:
s = θ · r (1)
Where:
θ - Central angle, in radiansr - Radius, in centimeterss = (2π - 132.844π/180) · (4 cm)

Answer:
405π
Step-by-step explanation:
Use the formula for Volume Of Cylinder (V=πr²h) where "V" represents the volume, "r" represents the radius, and "h" represents the height
The volume and the radius are given. (V=45π, r=3)
1. Solve for height
V=πr²h
45π=π3²h
45π/π=3²h
45=3²h
45=9h
45/9=h
h=5
2. Plug the new radius (3*3=9) into this formula and solve for "V"
V=π9²5
V=π81*5
V=405π

The radioactive element carbon-14 has a half-life of 5750 years. A scientist determined that the bones from a mastodon had lost 70.3% of their carbon-14. How old were the bones at the time they were discovered?
The bones at the time they were discovered when the radioactive element carbon-14 has a half-life of total 5750 years are 10062.5-year-old.
What is half-lives?Half lives is the time interval which is need to decay the atomic nuclei of a radioactive sample.
There is a scientist who determined that the bones from a mastodon had lost 70.3% of their carbon-14. Thus, the fraction remaining is,
f=1-(70.3/100)=1-0.703
f=1-(70.3/100)=0.297
Now the fraction remaining can be given as,
f=(1/2)ⁿ
Here, n is the half life elapsed. Put the value of fraction remaining.
0.297=(1/2)ⁿ
n=1.75
The radioactive element carbon-14 has a half-life of total 5750 years. Thus,
Years=1.75*5750
Years=10062.5
Thus, the bones at the time they were discovered when the radioactive element carbon-14 has a half-life of total 5750 years are 10062.5-year-old.

give two coterminal angles (one positive and one negative) and the reference angle -4 pi/5
The coterminal angle for the -4π/5 are -14π/5 , 6π/5 and reference angle is π/5 respectively.
What is coterminal angles?Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.
We have an angle:
-4π/5
To find the coterminal angle, add and subtract by 2π in the angle -4π/5
Coterminal angle:
= -4π/5 - 2π
= -14π/5
= -4π/5 + 2π
= 6π/5
Reference angle:
= π - 4π/5 (as the angle lies in the second quadrant)
= π/5
Thus, the coterminal angle for the -4π/5 are -14π/5 , 6π/5 and reference angle is π/5 respectively.

Step-by-step explanation:
If you factor out a 10 from the numerator and a 9 from the denominator, you should get the following:
Numerator = 10 (a + b)
Denominator = 9 (x - y)
Since we know that (a + b) = 3 and (x - y) = 5, we can rewrite it as:
Numerator = 10(3)
Denominator = 9(5)
Therefore, the answer is 30/45, or 2/3.

Using perfect squares simplification, it is found that the value of the desired limit is of -4.
When is a limit?It is the value of a function as x approach
In this problem, the limit we want to find is given by:
[tex]\lim_{x \rightarrow -2} \frac{x^2 - 4}{x + 2}[/tex]
If we just replace x by -2, we end with an undetermined limit, as we have 0/0.
However, the perfect square simplification states that:
a² - b² = (a - b)(a + b).
Hence:
x² - 4 = (x + 2)(x - 2).
Then:
[tex]\lim_{x \rightarrow -2} \frac{x^2 - 4}{x + 2} = \lim_{x \rightarrow -2} \frac{(x + 2)(x - 2)}{x + 2} = \lim_{x \rightarrow -2} x - 2 = -2 - 2 = -4[/tex]

Answer:
35 inches²
Step-by-step explanation:
Given Base and Height of triangle: 10 inches and 7 inches
To determine the area of a triangle, multiply the base and the height. Then divide the product of the base and the height by 2.
Therefore, the "area of triangle" formula is:
[tex]\boxed{\text{Area of a triangle} = \frac{\text{Base} \times \text{Height}}2}[/tex]
Now, substitute the base and the height in the formula. Then, simplify the expression to determine the area of the triangle provided.
[tex]\implies \text{Area of the triangle} = \dfrac{\text{10} \times \text{7}}2}[/tex]
[tex]\implies \text{Area of the triangle} = \dfrac{70}2} = \boxed{35 \ \text{in}^{2}}[/tex]
