Problem Statement:
What is the value of [tex]\frac{5^{4} }{5 ^{6} }[/tex] ?
To solve this problem, we must familiarize ourselves with the concept of exponents and rules that guides them.
Exponents are used by scientists to report higher orders of a number.
Such large and often recurring expression is usually made up of a base and an exponent value.
The exponent value is the power of the base; for example, 4³ has 4 as its base and 3 as the exponent.
Several rules guides solving an exponent, to this problem, the most applicable one is :
[tex]\frac{x^{a} }{x^{b} }[/tex] = [tex]x^{(a-b)}[/tex]
[tex]\frac{5^{4} }{5 ^{6} }[/tex] = [tex]5^{4-6}[/tex]
= [tex]5^{-2}[/tex]
= [tex]\frac{1}{25}[/tex]
Therefore the solution is 1 over 25

At the beach, a child uses a container in the shape of a cylinder to build a castle. The child completely fills the container with sand. The container has a height of 10 inches and a diameter of 12 inches there are 231 cubic inches in one gallon of sand. What is the approximate volume of san, in gallons in the container? Round your answer to the nearest gallon.
Answer:
5 gallons
Step-by-step explanation:
The container volume can be found from the formula for the volume of a cylinder:
V = πr^2h
V = π(6 in)^2(10 in) = 360π in^3 ≈ 1130.97 in^3
Then the number of gallons is ...
(1130.97 in^3)/(231 in^3/gal) = 4.896 gal
The approximate volume of sand is 5 gallons.

The probability of a tornado occurring in a subdivision in Tornado Alley in the United States has been estimated to be 0.2 for one occurrence, 0.03 for two occurrences, and 0.001 for three occurrences during the next 50 years. Assume that the chance of four or more occurrences is negligible during the next 50 years. If a tornado hits a structure, the probability that it will suffer damage is 70%. Assume that the damage from multiple tornadoes is statistically independent. What is the probability that a structure will not suffer any damage from tornadoes in the next 50 years
Answer:
Probability is 0.831727
Step-by-step explanation:
The probability can be calculated as below
There are multiple scenarios
Scanerio 1
0 occurance & No damage = 1 - 0.2 - 0.03 - 0.001 = 0.769
Scanerio 2
1 occurance & No damage = 0.2 x ( 1 - 0.7 ) = 0.06
Scanerio 3
2 occurance & No damage = 0.03 x ( 1 - 0.7 )^2 = 0.0027
Scanerio 4
3 occurance & No damage = 0.001 x ( 1 - 0.7 )^3 = 0.000027
P(structure will not suffer any damage) = Scanerio 1 + Scanerio 2 + Scanerio 3 + Scanerio 4 = 0.769 + 0.06 + 0.0027 + 0.000027 = 0.831727

Consider the linear function that is represented by the equation y = negative 10 x + 6 and the linear function that is represented by the equation y minus 36 = 8 (x minus 4). Which statement is correct regarding their slopes and y-intercepts?
Answer: The function that is represented by the equation y = negative 10 x + 6 has a steeper slope and a greater y-intercept.
Step-by-step explanation: I took the unit test on edge hoped this helped <3
We want to compare the slopes and y-intercepts of two given linear functions.
The comparations that we can make are:
The first line has a larger y-intercept.The second line has a larger slope.The general linear function in the slope-intercept is:
y = a*x + b
where a is the slope and b is the y-intercept.
Here, the two given lines are:
y = -10*x + 6
(here we can see that the slope is -10 and the y-intercept is 6).
The other line is:
y - 36 = 8*(x - 4)
Writing this in the slope-intercept form we get:
y = 8*x - 8*4 + 36
y = 8*x - 32 + 36
y = 8*x + 4
Then the slope is 8 and the y-intercept is 4.
Then the comparations that we can make are:
The first line has a larger y-intercept.The second line has a larger slope.If you want to learn more, you can read:

A clothing store uses comment cards to get feedback from its customers about newly added items. It recently introduced plus size fashion wear. Customers who purchased the items were asked to fill out an online comment survey giving 10% off the next purchase. The data are summarized in the table below. Which of the following would be an appropriate method for displaying the data shown in the table?
Response Frequency
Very satisfied 15
Satisfied 30
Less than fully satisfied 12
Not satisfied 4
a. 50%
b. 15%
c. 10%
d. 77%
e. 40%
Answer:
The percentage of customer would less likely to purchase next item is 26.2%
So, The nearest option will be (e).
Step-by-step explanation:
Given that,
The table of information is
Response = Very satisfied, Satisfied, less than fully satisfied and not satisfied
Frequency = 15, 30, 12 and 4
We need to calculate the total frequency
Using given frequency
[tex]Total\ frequency = 15+30+12+4[/tex]
[tex]Tota\ frequency = 61[/tex]
We need to calculate the total number of customers less or not fully satisfied
Using given data
[tex]x = 12+4[/tex]
[tex]x=16[/tex]
Where, x = total number
We need to calculate the percentage of customer would less likely to purchase next item
Using formula for percentage
[tex]percentage\ of\ customer=\dfrac{total\ number\ of\ customer}{total\ frequency}\times100[/tex]
Put the value into the formula
[tex]percentage\ of\ customer=\dfrac{16}{61}\times100[/tex]
[tex]percentage\ of\ customer=26.2\%[/tex]
Hence, The percentage of customer would less likely to purchase next item is 26.2%
So, The nearest option will be (e).

What exponent would complete this equation 0.005 = 5 x 10?
To the ? Power
Answer:
-3
Step-by-step explanation:
0.005 = 5 * [tex]10^?[/tex]
0.005 = 5 * 0.001
Thus, to find what 10 should be raised to, we should find which exponent of 10 gives us 0.001
We can do this by just testing a few numbers from 10^1 and down:
[tex]10^1 = 10\\10^0 = 1\\10^{-1} = 0.1\\10^{-2} = 0.01\\10^{-3} = 0.001[/tex]
As we can see, [tex]10^{-3}[/tex] = 0.001, thus the exponent in our equation is -3
A shorthand of this is counting the number of zeroes, 10^-1 has one zero, 10^-2 has two zeroes, and 10^-3 has three zeroes.
Since we were looking for 0.001, which has 3 zeroes, we can see that the correct exponent should be -3.

A company loses $780 as a result of shipping delay. The 6 owners of the company must share the loss equally. Write an expression to show the change in profit for each owner.
A. -780+6
B. 780/6
C. -780/6
D. -780 x 6
Answer: 780 divided by 6
Step-by-step explanation: it is C because you divide the lose into the 6 owners of the company.
The expression for the change in profit of each owner is the ratio of the total loss to the number of owners since the loss is shared equally, hence, the expression is -780 / 6
Given that :
Total loss = $780 ; since we are dealing with loss and not profit, we represent the amount lost as negative
Hence,
Total loss = -$780
Number of owners = 6
Change in profit of each owner = -$780 / 6
Therefore, the change in profit of each owner is -$780/6

Describe how to find the number of seats in the middle and lower levels of the stadium when solving for the variable only gives the number of seats on the upper level.
Answer:
Step-by-step explanation:
To find the value of the upper level you would have to solve the equation "x + (2x + 40) + (3x – 50) = 15,002" and the answer is 2,502. But to find the values of the middle and lower floors you need to apply the variable to separate equations. The lower level has 50 fewer than three times as many seats as the value of x. So to find the number of seats in the lower levels, you would have to multiply 2,502 by 3 (7,506) and subtract 50 (7,506 - 50 = 7456). The middle level has 40 more than twice as many seats as the upper level. To find the middle level you would multiply 2,506 by 2 (5004) and add 40 ( 5004 + 40 = 5044).

Answer:
C.) All living things need warm temperatures; it is always warm on Earth
Step-by-step explanation:
All living things do not need warmth to survive, and it is not always warm on Earth.
The correct answer All living things need warm temperatures; it is always warm on Earth.
What is Earth?Earth is the third planet from the Sun and the only place known in the universe where life has originated and found habitability.
The statement "All living things need warm temperatures; it is always warm on Earth" is not a reason that life can exist on Earth.
In fact, while many living things on Earth thrive in warm temperatures, there are also many that can survive and even thrive in cold environments, such as the polar regions.
Additionally, while Earth does have a relatively stable and moderate climate that supports a diverse range of life, it is not always warm everywhere on Earth.
There are many regions that experience cooler temperatures and even seasonal changes.
Therefore, the correct answer All living things need warm temperatures; it is always warm on Earth.
