if x=2 and t=4 what is the value of 1/8 (x^3 - 4) (t^2 + 8)?
Answers
Answer:
12
Step-by-step explanation:
Finding the 'value' means we need to calculate a number answer.
1/8 (x^3 - 4) (t^2 + 8)
Fill in 2 for x and 4 for t.
=1/8(2^3 - 4)(4^2 + 8)
inside of parenthesis we'll work on exponents first.
= 1/8 (8 - 4) (16 + 8)
Still inside of parenthesis, do the subtracting or adding next.
= 1/8 (4) (24)

if 200 group rooms are reserved and only 160 are ultimately occupied, the pick-up rate is group of answer choices 60% 70% 80% 90%
Answers
The pick-up rate in this scenario would be 80%. This is calculated by dividing the number of rooms occupied (160) by the number of rooms reserved (200), and then multiplying by 100 to get a percentage. So, (160/200) x 100 = 80%. This means that 80% of the reserved rooms were ultimately occupied.
It's important to note that a pick-up rate of 80% is generally considered to be a good result in the hospitality industry. It indicates that the hotel was able to accurately predict the number of rooms that would be needed by the groups, and that the groups themselves followed through on their reservations. A lower pick-up rate could suggest that the hotel overestimated demand, or that some of the groups cancelled their bookings at the last minute. On the other hand, a higher pick-up rate could indicate that the hotel was too conservative in its initial estimates, or that some of the groups requested additional rooms after the initial reservation was made. Ultimately, the pick-up rate is a useful metric for assessing the accuracy of a hotel's forecasting and planning processes.

Step-by-step explanation:
the key are always the 2 numbers in the middle.
you add number 2 to number 1 and put the result on top.
and you subtract number 2 from number 1 and out that result at the bottom.
starting with the example 3, -10 :
3 + -10 = 3 - 10 = -7 (goes on top).
3 - - 10 = 3 + 10 = 13 (goes at the bottom)
5, -3
5 + -3 = 5 - 3 = 2 (top)
5 - -3 = 5 + 3 = 8 (bottom)
18, ...
here we have the answers and need to find the original number.
let's call the missing number x.
I think 58 was put by you there and was originally empty. because 58 is not fitting to 22 below.
so,
18 - x = 22
x = 18 - 22 = -4
the missing number in the middle is -4.
and so the top is
18 + -4 = 18 - 4 = 14
two empty spots in the middle.
let's call the 2 missing numbers there x and y.
because the top and bottom numbers are given, we know :
x + y = -4
x - y = 8
x = y + 8
and we use this in the first equation :
y + 8 + y = -4
2y + 8 = -4
2y = -12
y = -6
x = y + 8 = -6 + 8 = 2
so, the 2 middle numbers from left to right are 2 and -6
The state of Colorado is 3 centimeters long and 4 centimeters wide on a map. A cartographer wants to use a scale factor of 1.5 to enlarge the map. What is the area of the enlarged map?
42 cm2
27 cm2
21 cm2
18 cm2
Answers
Answer:
27 cm^2
Step-by-step explanation:
Each dimension of the original map will be multiplied by 1.5 to get the dimensions of the new map because the cartographer intends to extend it by a scale factor of 1.5. The new map will therefore measure 3 * 1.5, or 4.5 centimetres, long and 4 * 1.5, or 6 cm wide.
We multiply the length by the width of the enlarged map to determine its area:
27 square centimetres are equal to 4.5 cm x 6 cm.
Consequently, the expanded map has a 27 square centimetre surface area.
Hope it helps! : )
The area of the enlarged map is 27 squared cm. Thus, the correct answer is option B.
Given that the state of Colorado is 3 cm long and 4 cm wide on the original map.
Using the scale factor of 1.5 to determine the new dimensions:
Length of enlarged map = 3 cm × 1.5
= 4.5 cm
Width of enlarged map = 4 cm × 1.5
= 6 cm
Now, we can calculate the area of the enlarged map using the new dimensions:
Area of enlarged map = Length × Width
= 4.5 cm × 6 cm
= 27 cm²
Therefore, the area of the enlarged map is 27 squared cm.

F. none of the above
Answers
The p-value of zero, while theoretically possible is effectively impossible, a p-value of .00000 is written as is
option A, "< .01".
It is important to first understand what a p-value represents. A p-value is a statistical measure that indicates the likelihood of obtaining the observed results of a study or experiment by chance, assuming that there is no true effect or difference between groups.
In hypothesis testing, a p-value of less than .05 (or .01, depending on the level of significance chosen) is typically considered to be statistically significant, indicating that the observed results are unlikely to be due to chance alone.
However, a p-value of exactly zero is not possible, as it would mean that the observed results are absolutely certain and could not have occurred by chance. Therefore, a p-value of .00000 (or any other extremely small value) is typically reported as "< .01" or something similar, indicating that the p-value is less than the chosen level of significance (in this case, .01).
Therefore, option A, "< .01", is the most accurate way to represent a p-value of .00000. The other options are either not precise enough (B and D), or incorrect (C and F).
A p-value of exactly zero is impossible, and a p-value of .00000 (or any other extremely small value) is typically reported as "< .01" to indicate that it is less than the chosen level of significance.

4. A submarine is traveling a 375 feet below sea leven

97
Answers
The submarine will take 14 seconds to safely reach the surface.
What is Speed?Speed is a measure of how quickly an object is moving, calculated as the distance traveled per unit time.
The submarine rises 183 feet, which means its depth decreases by 183 feet. Therefore, its depth is now 375 - 183 = 192 feet below sea level.
The submarine then dives 228 feet, which means its depth increases by 228 feet. Therefore, its depth is now 192 + 228 = 420 feet below sea level.
To reach the surface, the submarine needs to ascend a distance of 420 feet.
The speed of the submarine is given as 30 feet per second. Therefore, the time it will take for the submarine to reach the surface can be calculated as:
\(Time = \frac{Distance}{Speed} = \frac{420}{30}\)
= 14 seconds
Therefore, it will take the submarine 14 seconds to safely reach the surface.

Please explain the law of detachment and the law of syllogism.
Please also give 1 example for each law.
Answers
Law of Syllogism
The law of syllogism, also called reasoning by transitivity, is a valid argument form of deductive reasoning that follows a set pattern. It is similar to the transitive property of equality, which reads: if a = b and b = c then, a = c.There are also three parts involved in the law of syllogism, and each of these parts is called a conditional statement. A conditional statement has a hypothesis, which follows after the word if, and it has a conclusion, which follows after the word then. A letter is used to represent each phrase of the conditional statement. Let me introduce the pattern, and then we can look at some examples. Statement 1: If p, then q. Statement 2: If q, then r. Statement 3: If p, then r. Statements 1 and 2 are called the premises of the argument. If they are true, then statement 3 must be the valid conclusion.Law of Detachment
The law of detachment states that if a conditional statement is true and its antecedent is true, then the consequence must also be true.There are endless examples both in mathematics and beyond of the law of detachment. One example is a coffee shop that gives a free drink to every 25th customer. As a conditional statement, this is “If someone is the 25th customer, then they get a free drink. ”Thus, if you are the 25th customer, you know you will get a free drink. Likewise, if your friend is the 25th customer, you know he will get a free drink.Sources: https://www.storyofmathematics.com/law-of-detachment/

a landscape architect wishes to enclose a rectangular garden on one side by a brick wall costing $20/ft and on the other three sides by a metal fence costing $10/ft. if the area of the garden is 8 square feet, find the dimensions of the garden that minimize the cost.
Answers
the dimensions of the garden that minimize the cost are L = 2 ft and W = 4 ft.Let the length of the rectangular garden be L and the width be W. Then, the area of the garden is given as L x W = 8.
The cost C of enclosing the garden is given by:
C = 20L + 10(2L + W)
Substituting the value of W from the area equation, we get:
C = 20L + 10(2L + 8/L)
Differentiating C with respect to L and equating it to zero to find the minimum cost:
dC/dL = 20 + 20 - 80/L^2 = 0
Solving for L, we get L = 2 ft
Substituting L = 2 in the area equation, we get:
W = 4 ft
Therefore, the dimensions of the garden that minimize the cost are L = 2 ft and W = 4 ft.

4x + 12y-7z-20w = 26
3x + 9y-5z-28w = 36
(x, y, z, w)
Answers
The solution of the given system of equations is as follows:
x = x y = y z = -4/3x - 10/9y + 68/27
w = -1/147
Let's solve the given system of equations:
4x + 12y - 7z - 20w = 263x + 9y - 5z - 28w = 36
Divide the first equation by 4 and the second equation by 3 we have:
x + 3y - 7/4z - 5/2w = 26/43x + 3y - 5/3z - 28/3w = 12
Now, multiply the first equation by 3 and subtract from the second equation:
3(1x + 3y - 7/4z - 5/2w = 26/4)3x + 3y - 21/4z - 15/2w = 39/4- (3x + 3y - 5/3z - 28/3w = 12)1/3z + 11/3w = 7/4
Now, solve for z:
z = 21w - 28/3By substituting the value of z in terms of w in the first equation we get:
1x + 3y - 7/4(21w - 28/3) - 5/2w = 26/4x + 3y - 147/4w + 7 = 13/2
Multiply both sides by 2, and we get:2x + 6y - 147/2w + 14 = 13
Therefore,2x + 6y - 147/2w = -1/2
Now, solving for w:{147}/{2w}= {-1}/{2}
w = -1/147
By substituting the value of w in the equation x + 3y - 7/4z - 5/2w = 26/4, we get:
1x + 3y - 7/4z - 5/2(-1/147) = 26/4x + 3y - 7/4z + 5/294 = 13/12
Multiplying both sides by 12, we get:12x + 36y - 21z + 5 = 39
Now, solve for z:
z = -{4}/{3}x - {10}/{9}y + {68}/{27}
Hence, the solution of the given system of equations is as follows:x = x y = y z = -4/3x - 10/9y + 68/27w = -1/147
