What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The exponential expression is given as,
⇒ (4)⁵
In the exponential expression aⁿ, the n is the exponent or power and a is the base of the expression.
Then in the exponential expression (4)⁵, the number 5 is the exponent or power and the number 4 is the base of the expression.

A research group is comparing the learning outcomes of students who are taught a lesson using four different teaching techniques. There are 75 students in the school who can participate in the experiment. Using a table of random digits, the researchers will randomly place the students into five equally sized treatment groups suitable for comparison, four of which will receive a different teaching technique and one of which will remain a control group.
Which design is the most appropriate for this experiment?
A Randomly number each person with 1, 2, 3, 4, or 5. Assign the students to the treatment groups based on their label.
B Select a student, and identify the first digit reading from left to right on a random number table. If the first digit is 1 or 2, assign that student to the technique 1 group. Similarly, digits 3 or 4, 5 or 6, 7or 8, and 9 or 0 go with the technique 2, technique 3, technique 4, and control groups, respectively. Repeat this process for each student.
C Number each student from 1 to 75. Reading the numbers from left to right on a random number table, identify 60 unique numbers from 1 to 75. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.
D Number each student from 00 to 74. Reading the numbers from left to right on a table of random numbers and looking at two digits at a time, identify 60 unique two-digit numbers from 00 to 74. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.

1The first three figures in a pattern are shown here. What is the fourth
figure in the pattern?
Answer:
D
Step-by-step explanation:
The pattern is each end of the figure is expanding by one. A and C are automatically out because there is nothing in the middle of any figure in the previous pattern. B is out because it is the same as figure three. D is correct because it follows the rule of the pattern by expanind outwards one block on each end.

Answer: 41.5
Step-by-step explanation:
Number of tickets sold on day one = 23
Number of tickets sold on day two = 25
Number of tickets sold on day three = 35
Total tickets sold = 23 + 25 + 35 = 83
Since they want to share it equally, each boy will have:

Latisha owns two spas, one in Pine township and the other in Adams township. Each spa offers a 30-minute face, head, and neck massage to reduce muscle tension. However, therapists first ask each patient questions about their type of tension and stop about five minutes before the end of the 30 minutes to have time to prepare for the next patient. The number of minutes each therapist massages the patients at both spas is approximately Normally distributed, with the Pine spa having a mean of 22.6 minutes and a standard deviation of 1.7 minutes and the Adams spa having a mean of 21.0 minutes and a standard deviation of 2.8 minutes.

You and your friend go to an amusement park. You buy t tickets and spend $8 on food.Your friend buys t tickets and spends $12 on food. Is it possible that you and your friend spent the same amount at the amusement park.
Answer:
In the case of 4 tickets it can be possible
Step-by-step explanation:
Let us assume the number of tickets be t
Now as per the question the equations would be
For you = t + $8
For your friend = t + $12
In the case when you both spend the same amount so the above equations would be equivalent to each other
t + $8 = t + $12
So here the tickets would be 4 so this is possible that you both spend the same amounts
What type of punishment did the police officer give to the air pollution?
Answer:
Mistm Demeanor I think.. Hope this helps, tell me if it's incorrect!
Step-by-step explanation:
A police officer can not punish air pollution but can enforce laws and regulations to protect the environment.
What is air pollution?Air pollution means the presence of harmful substances in the air that can cause harm to all living beings.
We have,
Air pollution is not a living being so it can not be punished by a police officer.

An unfair coin with a probability of tails as 0.55 is tossed 8 times. Find the probability that a tail shows up more than 2 times.
Answer:
0.9115
Step-by-step explanation:
Using a binomial probability function :
P(x =x) = nCx * p^x * (1 - p)^(n - r)
Probability of success, p = 0.55
1 - p = 1 - 0.55 = 0.45
n = 8
x = 2
P(x > 2 ) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7) + p(x =8)
To save computation time, we could use the binomial probability calculator :
P(x > 2 ) = 0.9115

A fire ranger on a 150-ft-tall tower spots a fire at a 30° angle of depression. How
many feet away from the tower is the fire to the nearest tenth?
Answer:
259.8ft
Step-by-step explanation:
The distance from the tower to the fire to the nearest tenth is 260 feet.
Let the adjacent side be a.Given the following data:
Angle of depression = 30°.Opposite side = 150 feet.To determine how far away (in feet) from the tower is the fire to the nearest tenth:
How to apply trigonometric function.In order to solve this exercise, we would form a mental image of the scenario being described. The height of the tower is the opposite side while the distance from the tower to the fire is the adjacent side.
Next, we would apply the Tan trigonometric function:
[tex]Tan \theta = \frac{Opp}{Adj} \\\\Tan 30=\frac{150}{a} \\\\a=\frac{150}{Tan 30} \\\\a=\frac{150}{0.5774}[/tex]
a = 259.79 ≈ 260 feet.

Answer:
∠B = ∠C = 138°
∠D = 42°
Step-by-step explanation:
Angles between the parallel bases are supplementary:
∠B = 180° -∠A = 180° -42° = 138°
Right-side angles are the same measure as their mirrors across the line of symmetry.
∠C = ∠B = 138°
∠D = ∠A = 42°

g(x) = [tex]\sqrt{11-4x}[/tex]
[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
[tex](\frac{f}{g})(x)=\frac{1-x^2}{\sqrt{11-4x}}[/tex]
[tex](\frac{f}{g})(-1)=\frac{1-(-1)^2}{\sqrt{11-4(-1)}}[/tex]

= 0
(g + f)(x) = g(x) + f(x)
= [tex]\sqrt{11-4x}+1-x^2[/tex]
(g + f)(2) = [tex]\sqrt{11-4(2)}+1-(2)^2[/tex]

(g - f)(x) = g(x) - f(x)
= [tex]\sqrt{11-4x}-(1-x^2)[/tex]

(g - f)(-1) = [tex]\sqrt{11-4(-1)}-1+(-1)^2[/tex]
