5. Translate each of these statements into logical expressions using predicates, quantifiers, and logical connectives. The domain is all people on Earth. a) No one is perfect. b) Not everyone is perfect. c) All your friends are perfect. d) At least one of your friends is perfect. e) Everyone is your friend and is perfect. f) Not everybody is your friend or someone is not perfect.
Solution :
A logical expression may be defined as those equation or expression which is either viable or inviable.
In the context, translating each statement into a logical expression using the predicates, the quantifiers, and the logical connectives.
Let P(x) be the propositional function "x is perfect"
Let F(x) be the propositional function "x is your friend"
And the domain is all the people
a). No one is perfect
[tex]$\forall \ x \rightharpoondown P(x)$[/tex]
b). Not everyone is perfect.
[tex]$\rightharpoondown \forall \ x\ P(x)$[/tex]
c). All your friends are perfect.
[tex]$\forall \ x (F(x)\rightarrow P(x))$[/tex]
d). At least one of your friends is perfect.
[tex]$\exists \ x \ (F(x) \wedge P(x))$[/tex]
e) Everyone is your friend and is perfect.
[tex]$\forall \ x \ F(x) \wedge \ \forall \ x \ P(x)$[/tex]
f). Not everybody is your friend or someone is not perfect.
[tex]$(\rightharpoondown \ \forall \ x \ F(x) ) \ \wedge (\exists \ x \ \rightharpoondown \ A (x))$[/tex]
For f(x) = 5x – 3 and g(x) = 2x2 - 5, find the following functions.
a. (fog)(x); b. (gof)(x); c. (fog)(2); d. (gof)(2)
Answer:
See answer below
Step-by-step explanation:
Given the functions f(x) = 5x – 3 and g(x) = 2x2 - 5, find the following functions.
a)(fog)(x) = f(g(x))
f(g(x)) = f(2x^2-5)
f(g(x)) = 5(2x^2-5) - 3
f(g(x)) = 10x²-25-3
f(g(x)) = 10x² - 28
b) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 2(25x²-30x+9)-5
g(f(x)) = 50x²-60x+18-5
g(f(x)) = 50x²-60x+13
c)(fog)(2) = f(g(2))
f(g(x)) = f(2x^2-5)
f(g(2)) = 10(2)² - 28
f(g(2)) = 10(4)-28
f(g(2)) = 12
d) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 50x²-60x+13
g(f(2)) = 50(2)²-60(2)+13
g(f(2)) = 200-120+12
g(f(2)) =80+12
g(f(2)) = 92

Which statement best describes a characteristic of a CD (certificate of deposit)
account?
A. A CD has a predetermined time limit before a withdrawal can be made.
B. A CD is as flexible as a regular savings account but with higher interest
rates.
C. A CD allows for more withdrawals than a money market account.
OD. A CD features withdrawal minimums that are less than the account balance.
Answer: A.) A CD has a predetermined time limit before a withdrawal can be made.
Hope this helps :)
A CD has a predetermined time limit before a withdrawal can be made is the statement best describes a characteristic of a CD.
What is Deposit?A deposit is the act of placing cash with some entity, most commonly with a financial institution, such as a bank
A CD has a predetermined time limit before a withdrawal can be made.
This is the best statement that describes a characteristic of a CD (certificate of deposit) account.
A CD is a type of savings account that requires the depositor to commit to leaving their funds in the account for a predetermined period of time, called the term or maturity.
During this time, the funds are locked in and the depositor cannot withdraw them without incurring a penalty.
This makes a CD less flexible than a regular savings account but typically offers higher interest rates.
CD accounts do not usually allow for more withdrawals than a money market account, and there are no withdrawal minimums that are less than the account balance.
Hence, A CD has a predetermined time limit before a withdrawal can be made is the statement best describes a characteristic of a CD.

Manufacture of a certain component requires three different machining operations. Machining time for each operation has a normal distribution, and the three times are independent of one another. The mean values are 20, 15, and 30 min, respectively, and the standard deviations are 1, 2, and 1.5 min, respectively. What is the probability that it takes at most 1 hour of machining time to produce a randomly selected component
Answer:
0.0314 = 3.14% probability that it takes at most 1 hour of machining time to produce a randomly selected component
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Sum of normal variables:
When normal variables are added, the mean is the sum of the means while the standard deviation is the square root of the sum of the variances.
The mean values are 20, 15, and 30 min, respectively:
This means that [tex]\mu = 20 + 15 + 30 = 65[/tex]
The standard deviations are 1, 2, and 1.5 min, respectively.
This means that [tex]\sigma = \sqrt{1^2 + 2^2 + 1.5^2} = 2.6926[/tex]
What is the probability that it takes at most 1 hour of machining time to produce a randomly selected component?
Mean and standard deviation are in minutes, so this is the pvalue of Z when X = 60.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60 - 65}{2.6926}[/tex]
[tex]Z = -1.86[/tex]
[tex]Z = -1.86[/tex] has a pvalue of 0.0314
0.0314 = 3.14% probability that it takes at most 1 hour of machining time to produce a randomly selected component

Write each number in standard form.
1.
2.
3. 500 + 60 + 6
BB
Answer:
566
Step-by-step explanation:
We need to write the following number in standard form.
500 + 60 + 6
Here, the first no is 500, the second number is 60 and the other number is 6.
It can be done as follows :
500 + 60 = 560
And
560 + 6 = 566
So, the standard form is 566 inc which 6 is at one's place, another 6 at tens place and 5 at hundred places.

Please help, I’m not sure if I’m doing this right (math). 9 says 9x-47 btw.
Answer:
<1 = 43
<2= 17
<3= 120
<4=60
<5= 60
<6= 60
<7 =17
<8= 120
<9= 43
Step-by-step explanation:
< 4, <5, <6 are all 60
<3 and <4 are a linear pair, so they add to 180. Since <4 is 60, <3 is 180-60= 120
<6 and <8 are a linear pair, so they add to 180. Since <6 is 60, <8 is 180-60= 120
Angles 1 and 9 are congruent
4x+3=9x-47
50=5x
10=x
<1= 4(10)+4= 43
<9-9(10)-47=43
Now you have 2 angles for the triangle A B D- subtract the 2 known from 180
<2= 180-43-120=17
<7= 180-43-120=17

Florida Fish and Wildlife is having problems with the growing population of Pythons in the Everglades.
As we can see in the graph the annual growth of the python population from the beginning of 2000 to 2010 is continuously increasing between 0 to 10,
Mathematically,
x ∈ [0, 10] or
0 ≤ x ≤ 10
Thus, the domain of the graph is [0, 10] or 0 ≤ x ≤ 10 when the annual growth of the python population from the beginning of 2000 to 2010.

A telephone pole has a wire attached to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor point is 23 feet less than the height of the pole. If the wire is to be 9 feet longer than the height of the pole, what is the height of the pole?
9514 1404 393
Answer:
56 feet
Step-by-step explanation:
Let x represent the height of the pole. Then the distance to the anchor point is (x-23), and the length of the wire is (x+9). The Pythagorean theorem tells you the relation between these values is ...
(x+9)² = x² +(x -23)²
0 = x² -64x +448 . . . . . subtract the left side, put in standard form
0 = (x -8)(x -56) . . . . . . factor
The solutions to the quadratic are x=8 and x=56. For our purposes, we require x > 23 so the distances are positive. That means x=56 is the solution of interest.
The pole is 56 feet tall.

nearest hundredth.
A
in 2
in
Answer:
94.99
Step-by-step explanation:
Hi,
The formula to find the area of a circle is: A = πr²
So...
A = 3.14 (r)²
The radius of the circle is 5.5 because half of the diameter is the radius.
A = 3.14 (5.5)²
A = 3.14 (30.25)
A = 94.985 rounded is 94.99
