Let D be the set of all students at GSU students, and let M(s) be 's is a math major," let C(s) be s is a computer science student," and let E(s) be "s is an engineering student." Express each statement using quantifiers, variables, and the predicates M(s), C(s), and E(s). a. No computer science students are engineering students. b. Some computer science students are also math majoers.
Answer:
Step-by-step explanation:
Recall the logic quantifiers [tex]\forall, \exists[/tex] which means for all/for every and exists.
a) This means that for every student in D that is a computer science this implies that the student is not an engineering student. So for a student s in D such that C(s) then E(s) is false. This is symboled by
[tex]\forall s \in D C(s) \implies \neg E(s)[/tex]
b) By saying "some computer science students" this means that there exists some studenst that study computer science and are also math majors. This is symboled by
[tex]\exists s \in D C(s)\land M(s) [/tex]
7. A shopkeeper buys 300 identical articles a tota
cost of $1500. He sells 260 articles at a price
20% above the cost price Each of the remain
anicles is sold at a price that is 50% of the si
price of each of the 260 articles Express the
shopkeeper's profit as a percentage of his cost price?
Answer this Q. so that i will mark u as tge brainliest!
Step-by-step explanation and answers:
300 articles at a total cost of $1500:
$1500 / 300 = $5 / article
Sells 260 articles at a price 20% above this ^ price:
20% of $5 is $1, so $5 + $1 = $6
Then he sells 260 articles at the price of ^ $6
260 * $6 = $1560
Each of the remaining articles is sold at a price that's 50% of the 260 he sold.
He sold those for $6, so he would now sell the last 40 for $3
From the remaining 40 articles, he makes 40 * $3, or $120
The shopkeeper made $1560 + $120 = $1680, which is $180 more than he bought them for ($1500)
Therefore, he made a profit percentage of $180 / $1500, (the amount of profit over the amount spent).
He made a profit percentage, compared to the cost price, of 12%.

2y/5y cube + 4y square + 6y
Answer:
here down is the answer
(2y/5y)^3+4y^2+6y
8y^3/125y^3 +16y^2+6y
8/125+16y^2+6y
8/125+16y^2+6y=0
16y^2+6y+8/125=0
it is in the form of quadratic equation
formula :
x=(-b+-square root of b^2-4ac) /2a
here a=16,b=6&c=8/125
x=(-b+-square root of b^2-4ac)/2a
x=(-6+-square root of 36-4.09)/2a here 4.09 came by calculation
x=(-6+-31.91)/2
so
x=(-6+31.91)/2 first (+);
x=25.91/2
x=12.955;
x=(-6-31.91)/2 then(-);
x=-37.91/2
x=-18.955 ;
ans is = 12.955&-18.955;

RS given ST=5and RT=11
.
Answer: FE is 7 and RS is 6.
Step-by-step explanation:
13 - 6 = 7
11-5= 6
Answer:
FE = 7
RS = 6
Step-by-step explanation:
for the first line, we know that line GE is 13 units long, and segment GF is 6 units. simply subtract 6 from 13 to get the length of segment FE.
13 - 6 = 7
You can do the same thing for the second problem.

A line has the equation y=x+3
What are the coordinates of the point where the line intersects the y and x axis?
Answer:
(0, 3 ) and (- 3, 0 )
Step-by-step explanation:
Where the line crosses the y- axis the x- coordinate is zero.
Substitute x = 0 into the equation and solve for y
y = 0 + 3 = 3
Thus the y- intercept is (0, 3 )
Where the line crosses the x- axis the y- coordinate is zero.
Substitute y = 0 into the equation and solve for x
0 = x + 3 ( subtract 3 from both sides )
- 3 = x
Thus the x- intercept is (- 3, 0 )
What is the surface area of the rectangular pyramid below?
A. 363 units2
B. 484 units2
C. 1026 units2
D. 242 units2
Answer:
Option (A). 363 units²
Step-by-step explanation:
Surface area of the rectangular pyramid = Area of the rectangular base + Area of the lateral sides of the pyramid
Area of the rectangular base = Length × Width
= 11 × 11
= 121 units²
Area of the lateral sides = 4(Area of one lateral side)
= 4[[tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]]
= 2(11)(11)
= 242 square units
Area of the rectangular pyramid = 121 + 242
= 363 square units
Therefore, Option (A) will be the answer.

If 0 < f ≤ 90 and cos(22f − 1) = sin(7f + 4), what is the value of f?
f = 3
f = 4
f = 5
f = 6
Answer:
f = 3Step-by-step explanation:
Given the equation cos(22f − 1) = sin(7f + 4), the following steps must be followed in order to get the value of f;
From the trigonometry identity, sin(90-theta) = cos theta.
cos(22f-1) = sin (90-(22f-1))
cos(22f-1) = sin (90-22f+1)
cos(22f-1) = sin (91-22f)... 3
substituting eqn 3 into the original equation given, we will have;
sin (91-22f) = sin(7f + 4)
91-22f = 7f+4
7f+22f = 91-4
29f = 87
f = 87/29
f = 3
A correct option is an option (a)
Given function is,
[tex]cos(22f-1) = sin(7f + 4)[/tex]
As we know the relation,
[tex]cosx=sin(90-x)[/tex]
Now, apply the above relates to the given function.
[tex]cos(22f − 1) = sin(7f + 4)\\sin(90-(22f-1))=sin(7f + 4)\\90-22f+1=7f+4\\-22f-7f=4-91\\-29f=-87\\f=3[/tex]
So, the required value is [tex]f=3[/tex]

A bag contains four yellow jerseys numbered one to four. The bag also contains three purple jerseys numbered one to three. You randomly pick a jersey. It is purple or has an even number.
A.0.714 B:0.727 C:0.778 D:286
Answer:
6/7
Step-by-step explanation:
Total number of jerseys = 4 + 3 = 7
Now, the probability of picking a purple Jersey = number of purple jerseys/total number of jerseys = 3/7
Now let’s look at picking a jersey with even number
Even number jerseys are yellow two and yellow four and also purple two
So we have 3 even numbered jersey. The probability of picking an even numbered jersey is 3/7
In probability, once we have or, we add
The probability of picking an even numbered jersey or a purple jersey = 3/7 + 3/7 = 6/7
Profit is the difference between revenue and cost. The revenue, in dollars, of a company that makes skateboards can be modeled by the polynomial 2x3 + 30x – 130. The cost, in dollars, of producing the skateboards can be modeled by 2x3 – 3x – 520. The variable x represents the number of skateboards sold. What expression represents the profit?
A. 27x – 650
B. 27x + 390
C. 33x – 650
D. 33x + 390
Answer:
We need to subtract both equations. 2x3+30x-130-2x3+3x+520
that gives
30x-130+3x + 520
33x+390
D is answer
Answer:
D. 33x + 390
Step-by-step explanation:
Profit is the difference between revenue and cost so subtract the given polynomials:
2x³ + 30x – 130 - (2x³ – 3x – 520) = 2x³ + 30x – 130 -2x³+3x+520
combine like terms: 33x +390

Answer:
Step-by-step explanation:
The graph of a function and its inverse will always reflect through the line
y = x.
This is because a function has a specific set of coordiates, (x, y). That function's inverse has a set of coordinates that flips the x and y coordinates. For example, if a function has a set of coordinates (0, 1), (2, 3), (4, 5) then its inverse will have the coordinates (1, 0), (3, 2), (5, 4). If you plot the function's points and then the inverse's points in the same plane (meaning on the same graph) and connect the dots, you will see that the function and its inverse are reflections of each other through y = x. Below is an example of this. The dotted purplish line is the line y = x.
Given the equation y = 2x - 8, what is the slope and the y-intercept? A.) m = 8 and b = 2 B.) m = 2 and b = 8 C.) m = 2 and b = -8 D.) m = -8 and b = 2
Answer:
C.) m = 2 and b = -8
Step-by-step explanation:
Generally:
In an equation of the form y = mx + b
the slope is m
the y-intercept is b
In our equation y = 2x - 8 = 2x + (-8)
then
m = 2 and b = -8

f = 4m + 3m -1
f = 7m - 1
Adding 1 to both sides
f+1 = 7m
Dividing both sides by 7
m = [tex]\frac{f+1}{7}[/tex]
Answer:
m= (f+3)/(f-4)

It is not clear from the question, but I assume it is:
f= (4m+3)/(m-1)so the solution is:
f= (4m+3)/(m-1)f(m-1)=4m+3fm-f= 4m+3fm- 4m= f+3m(f-4)= f+3m= (f+3)/(f-4)Find the values of x and y.

Answer:
18 x, 36y.
Step-by-step explanation:
18x, 36y.
The ratio of x to y is 1 to 2. What is the value of x if y=4x-36?
So y: 2x (since its double the x)
So
2x = 4x - 36
Doing the math....
18x. since y= 2*x, 36y.
(I got help for this one, credits to jess :) )

The value of X is 18.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The ratio of X and Y = 1 : 2
This means,
X/Y = 1/2
X = x
Y= 2x
Now,
y = 4x - 36
From (2),
2x = 4x - 36
36 = 4x - 2x
36 = 2x
x = 18
Now,
From (1),
X = x = 18
Thus,
The value of X is 18.
