Answers
In Linear pair, 52° is the value ∠AZJ .
What is Linear pairs?
When two lines meet at a single point, a pair of linear angles is created. If, following the junction of the two lines, the angles are next to one another, they are said to be linear. A linear pair's total angles are always equal to 180 degrees.
A pair of adjacent angles is said to be a linear pair if the total of the two angles' (measured) angles is 180°. This means that a linear pair of angles always adds up to 180°. The linear pair of 30°, for instance, is 150°; the linear pair of 70°, 110°; etc.
∠JZF or ∠HZG
Linear pairs form supplementary angles.
∠AZJ = ∠AZH - ∠HZA
= 90° - 38°
∠AZJ = 52°

what is unitary method ?In mathematics, the unitary approach entails determining the value of a single unit in a certain circumstance and using that value to resolve other issues that are connected to it. It is a quick and efficient method for handling issues involving direct proportion, indirect proportion, and other circumstances of a same nature. In disciplines including mathematics, science, business, and engineering, the unitary technique is widely employed.

Let V be the computer's starting value.
The computer's value drops to V/2 after four years.
The computer's value is decreased to V/2 1/2 = V/4 after six years.
We are informed that the PC will be worth $835 after six years. When we set this equal to V/4, we obtain:
V/4 = 835
Adding 4 to both sides results in:
V = 4 × 835 = $3340
Thus, the computer was initially worth $3340 as the PC will be worth $835 after six years.

Which of the following graphs is described by the function below?
[tex]y=x^{2} -6x-7[/tex]
A.) Graph A
B.) Graph B
C.) Graph C
D.) Graph D
Answers
The given function [tex]y=x^2 - 6x - 7[/tex] describes the graph A.
What is function?
In mathematics, a function is a relation between a set of inputs (the domain) and a set of possible outputs (the codomain) with the property that each input is related to exactly one output.
We can solve this Function by substituting the 0 for Y.
To find the value of x when y is equal to 0, we can substitute 0 for y in the equation and solve for x:
[tex]0 = x^2 - 6x - 7[/tex]
To solve for x, we can use the quadratic formula:
x = (-b ± [tex]\sqrt{(b^2 - 4ac)}[/tex]) / 2a
In this case, a = 1, b = -6, and c = -7. Substituting these values into the formula, we get:
x = (-(-6) ± [tex]\sqrt {((-6)^2 - 4(1)(-7)}[/tex])) / 2(1)
Simplifying:
x = (6 ± [tex]\sqrt{64}[/tex]) / 2
x = (6 ± 8) / 2
x = 7 or x = -1
Therefore, when y is equal to 0, x can be either 7 or -1.
Therefore the given function describes the graph A.

Which of the following explains why it is easier to reject the null hypothesis with a one-tailed test than with a two-tailed test with all the same parameters?
a. Because the standard deviation in a one-tailed test is larger than that for a two-tailed test
b. Because z-scores are calculated differently in a one-tailed test
c. Because the critical region is all on one side in a one-tailed test and needs to be split between the two tails in a two-tailed test
d. Because a two-tailed test uses a bimodal distributio
Answers
Because the critical region is all on one side in a one-tailed test and needs to be split between the two tails in a two-tailed test.
What is the difference between a one-tailed test and a two-tailed test in hypothesis testing?In a one-tailed test, the alternative hypothesis is directional and the critical region is all on one side of the distribution. In a two-tailed test, the alternative hypothesis is non-directional and the critical region is split between the two tails of the distribution.
Why is it easier to reject the null hypothesis with a one-tailed test than with a two-tailed test?It is easier to reject the null hypothesis with a one-tailed test because the critical region is all on one side of the distribution, making it more likely to observe a significant difference and reject the null hypothesis. In contrast, the critical region is split between the two tails in a two-tailed test, making it less likely to observe a significant difference and reject the null hypothesis.

Answer:
The effect on the graph of the function f(x) = 2^x when f(x) is replaced with f(x − 3) is that it translates horizontally 3 units right.
When a function is replaced with f(x - c), where c is a positive constant, the graph of the function shifts horizontally c units to the right. Similarly, if c is negative, the graph shifts horizontally c units to the left.
Therefore, replacing f(x) with f(x - 3) in the function f(x) = 2^x shifts the graph of the function horizontally by 3 units to the right.

The formula for the area of a circle is:

A town has a population of 12,000 and grows at 3. 5% every year. What will be the population after 7 years, to the nearest whole number?
Answers
If the population growth rate is 3.5 percent every year then the population of the town after 7 years would be 14940.
Given that population grows 3.5 percent every year.
So, the increase in population after one year
= 3.5% of 12000
= (3.5/100) × 12000
= 420
Thus the increase in population after 7 year would be,
= population increase in one year × 7
= 420×7 = 2940
Hence population of the town after 7 years = (present population + increase in population)
= 12000 + 2940
= 14940
So the population of the town after 7 years with 3.5 % growth every year would be 14490.

Assuming he drives at a speed of 60 miles per hour, it will take him 5.5 hours to drive the 330 miles.
How long does it takes him to drive the 330 miles?If Harold drives 330 more miles at the same rate of 60 miles per hour, we can use the formula:
distance = rate x time
Let t be the time in hours it takes to drive the additional 330 miles. Then we have:
330 = 60t
Solving for t, we get:
t = 330/60
t ≈ 5.5 hours
Therefore, it takes approximately 5.5 hours to drive the additional 330 miles at a rate of 60 miles per hour.

Answers
The probability of selecting a vowel from a hat with letters of the alphabet is 5/26 or approximately 0.1923. There are 5 vowels and 26 total letters.
There are 5 vowels in the English alphabet: A, E, I, O, and U. Therefore, the number of favorable outcomes (i.e., the number of vowels in the hat) is 5.
There are a total of 26 letters in the English alphabet. Therefore, the number of possible outcomes (i.e., the number of letters in the hat) is 26.
The probability of selecting a vowel is the ratio of the number of favorable outcomes to the number of possible outcomes:
P(vowel) = number of favorable outcomes / number of possible outcomes
P(vowel) = 5 / 26
Therefore, the probability of selecting a vowel is 5/26 or approximately 0.1923 (rounded to four decimal places).

a gallon of milk is approximately 4 liters. how many gallon containers of air will it take to full one cubic meter (1 m3)? select the appropriate set-up for this calculation.
Answers
A gallon of milk is approximately 4 liters. 250 gallon containers of air will it take to full one cubic meter.
The setup for calculating how many gallon containers of air it will take to fill one cubic meter is:
1 m³ × 1000 L/m³ ÷ 4 L
A gallon of milk is approximately equal to 4 liters.
1 cubic meter (1 m³) of air is equal to 1000 liters.
One cubic foot of water contains 7.48 gallons. Dividing the total number of gallons by 7.48 will get the cubic feet equivalent.
To convert liters to gallons,
divide by 4 (since 1 gallon is approximately equal to 4 liters).
The calculation for how many gallon containers of air it will take to fill one cubic meter is:

The area of the figure composing of a rectangle and a semi-circle is 105.12 ft².
What is the area of the composite figure?The figure in the image composes of a rectangle and a semi-circle.
The area of a rectangle is expressed as;
Area = Length × Width
The area of a semi-circle is expressed as;
Area = 1/2 × πr²
First, we find the area of the rectangle.
Area = Length × Width
Plug in Length = 10ft and Width = 8ft
Area = 10ft × 8ft
Area = 80ft²
Next, find the area of the semi-circle.
Area = 1/2 × πr²
Since diameter = 8ft, radius r = diameter/2 = 8ft/2 = 4ft
Area = 1/2 × 3.14 × (4ft)²
Area = 1/2 × 3.14 × 16 ft²
Area = 25.12 ft²
Now, area of the composite figure will be:
Area of the rectangle + Area of the semi-circle.
Area = 80ft² + 25.12 ft²
