To denote the population standard deviation of the pulse rates of women (in beats per minute), we can use the symbol σ (sigma). Now, let's identify the null and alternative hypotheses.
Null hypothesis (H₀): There is no significant difference in the pulse rates of women.
Alternative hypothesis (H₁): There is a significant difference in the pulse rates of women.
These hypothesis can be tested using appropriate statistical methods to determine if there's evidence to support or reject the null hypothesis.

write the coordinates of the image of P(-2,5) reflected in the line of y=2
Answer:
Q(-2, -1)
Step-by-step explanation:
P(-2, 5) is 3 units ABOVE the line y = 2. If we reflect this point in the line y = 2, we end up with a point Q(-2, -1), where the '-1' comes from subtracting 3 from 2.
A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points. The new coordinate of the point P is (-2,-1).
What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
If the point and the line are plotted on the graph as shown below. It can be observed that point P is 3 units away from the line.
Now, since the point is reflected along the horizontal line, therefore, the x-coordinate of the point will not change, while the y-coordinate will be 3 units below the line.
Thus, the new coordinate of the point can be written as,
New-coordinate = (-2, 2 - 3) = (-2, -1)
Hence, the new coordinate of the point P is (-2,-1).

Frank the earth, llc signed a three-year lease for office space. This lease is considered an what?
Answer: Long-term Liability
Step-by-step explanation:
This question relates to the classification of the lease above in accounting.
A long term liability is a payment that is owed by a company for a period lasting more than a year.
When a lease is for more than a year as is the case here, you take the present value of the lease and consider that amount to be a long term liability because it would represent an amount that the company is to pay for more than a single period.,

What is the complete factorization of the polynomial below?
x^3- 2x²+x-2
A. (x-2)(x + 1)(x - 1)
B. (x + 2)(x + 1)(x - 1)
C. (x + 2)(x - 1)(x - 1)
D. (x-2)(x - 1)(x - 1)
Answer:
Let's start by rearranging this polynomial.
x^3 - 2x^2 + x - 2
x^3 + x - 2x^2 - 2
Now, factor out the common terms in the first two terms, and the second t wo terms. So we have: x(x^2 + 1) - 2(x^2 +1)
Apply the distributive property, and you have: (x-2)(x^2+1), which can't be factored further.
There's definitely something wrong with the answer choices here, or the problem itself.
Hopefully this helps!
The complete factorization of the polynomial is,
⇒ (x + i) (x - i) (x - 2)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The polynomial is,
⇒ x³ - 2x² + x - 2
Now, We can factor the polynomials as;
The polynomial is,
⇒ x³ - 2x² + x - 2
⇒ x² (x - 2) + 1 (x - 2)
⇒ (x² + 1) (x - 2)
⇒ (x + i) (x - i) (x - 2)
Therefore, The complete factorization of the polynomial is,
⇒ (x + i) (x - i) (x - 2)

Construct a parallelogram whose diagonals
are 5.4 cm and 6.2 cm and an angle between
them is 70°.
Answer:
15.73 cm²
Step-by-step explanation:
Construct a parallelogram whose diagonals are 5.4 cm and 6.2 cm and an angle between them is 70°.
To construct the parallelogram, we find the Area of the parallelogram.
Area of a parallelogram = ½ × d1 × d2 × sin (y)
Where
d1 = Diagonal 1 = 5.4 cm
d2 = Diagonal 2 = 6.2 cm
y = Angle between them = 70°
Area of the parallelogram =
1/2 × 5.4 × 6.2 × sin 70
= 15.730454472 cm²
Approximately = 15.73 cm²

How to round the numbers?To round a number to the nearest tenth, we must observe the second decimal digit of the number:
If the second decimal digit is less than five, the first digit remains constant and the other decimal digits are removed, example, 387.34 = 387.3.If the second decimal digit is at least five, one is added to the first digit and the other decimal digits are removed, example, 387.35 = 387.4.More can be learned about rounding at https://brainly.com/question/28128444

N
a. a
b. b
Answer:
a = 139.1
b = 56.2
Step-by-step explanation:
A. Reference angle = 68°
Opp = a
Hyp = 150
Therefore:
Sin 68 = opp/hyp
Sin 68 = a/150
150*sin 68 = a
a = 139.1 (nearest tenth)
B. Reference angle = 68°
Adj = b
Hyp = 150
Therefore:
Cos 68 = adj/hyp
Cos 68 = b/150
150*cos 68 = b
b = 56.2 (nearest tenth)
