Of the students living in the dormitories at aa€‹ university, 65% live at the westa€‹ hall, and the rest at the south tower. A sandwich shop randomly mails a coupon for a free sandwich to 24% of those at the westa€‹ hall, and to 19% of those living at the south tower. Let D be the event that the person receive a coupon, E1 be the event that the person is living in the westa€‹ hall, and E2 be the event that the person is living in the south tower. A student living in a dormitory is randomly chosen.
Required:
Find the probability that this person received a coupon. Also write an expression that models the probability.
Answer:
The answer is "Option A".
Step-by-step explanation:
Dormitory students.
Please find the complete question in the attched file.
[tex]p (E_1) =0.73[/tex]indicates that teachers live in the west hall.
[tex]p (E_2) =0.27[/tex] indicates that the students live in the south tower.
[tex]P (D|E_1) =0.25[/tex] describes the likelihood which West Hall students received free coupons.
[tex]P (D|E_2) =0.19[/tex] indicates that students in the south tower were given free coupons.
[tex]P(D)=P(D|E_1)P(E_1)+P(D|E_2)P(E_2)\\\\=0.25 \times 0.73 +0.19 \times 0.27\\\\=0.234[/tex]
To maximize the probability that the person selected at random will receive the coupon, multiply the following numbers by the possibility of success of the coupon:

The given binomials are (2x– 1) and (x/2 -2/3).
We need to find the product of the given binomials.
How to multiply two binomials?The binomials are multiplied as:
Step 1: Multiply the first term of each binomial.
Step 2: Now multiply the outer term of each binomial.
Step 3: Once this is done, now multiply the inner terms of the binomials.
Step 4: Now the last terms are multiplied.
Now, (2x– 1) × (x/2 -2/3)
=2x × x/2 -1 × x/2 - 2x × 2/3 - 1 (-2/3)
=x²-x/2-4x/3+2/3
=x²+(-3x-8x)/6+2/3
=x²-11x/6+2/3
Therefore, the product of the given binomials is x²-11x/6+2/3.

Bethany is making a rectangular fenced- in area for her rabbit in her yard. The area measures 4 3/4 feet wide by 2 yards long.
what's the total length of fencing that Bethany will need in feet?
Answer:
The total length of fencing that Bethany will need is 21.5 feet.
Step-by-step explanation:
Since Bethany is making a rectangular fenced- in area for her rabbit in her yard, and the area measures 4 3/4 feet wide by 2 yards long, to determine what's the total length of fencing that Bethany will need in feet the following calculation must be performed:
1 yard = 3 feet
2 yards = 6 feet
3/4 = 0.75
4.75 x 2 + 6 x 2 = X
9.5 + 12 = X
21.5 = X
Therefore, the total length of fencing that Bethany will need is 21.5 feet.

The correct answer is 520 square units that is option D.
What is the formula for surface area of prism?
The formula used to find the surface area S of right prism is S=bh+pH.
In the formula b is the base, h is the height of the right angle triangle formed in the prism and p is the perimeter of the triangle, H is the width of the prism.
What is the unknown side of the triangle?Let x be the hypotenuses of the right angle triangle of the prim.
Use Pythagoras theorem in the right angle triangle to find the value of x.
[tex]15^{2} +8^{2} =x^{2}[/tex]
[tex]x^{2} =289[/tex]
On solving this we will get x=17.
What will be the perimeter of the triangle?On adding all the sides of the triangle the perimeter of the triangle is 8+15+17=40.
What will be the surface area of the prism?By calculation and given information, we have b=8, h=15, p=40 and H=10.
Now we will substitute all the values in the formula to find the surface area.
S=(8)(15)+(40)(10)=120+400=520 Square units.
Therefore, the correct option is D.

Please help me, GodBless.
Answer:
(-1 , -1)
Step-by-step explanation:
You can simply use the substitution method to solve for this system. For simplicity, let's substitute the second equation (y=x) into the first equation. Basically switch the y's for x's in the first equation.
Therefore you get:
-6x - 5x = 11
-11 x = 11
x = -1
Then use the second equation that you substitued in to solve for y (y=x):
y = x
y = -1
So the final point is (-1, -1)

86 28 34 99 77 49 50 43 34 70 42 90 87 68 67 72 87 94 47 76
Using a calculator :
Sample mean, xbar = 65
Sample. Standard deviation s = 22.35
Confidence interval :
Xbar ± standard Error
Standard Error = Tcritical * s/√n
TCritical at 95%, df = 19 = 2.093
Standard Error = 2.093 * (22.35/√20) = 2.339
Lower boundary = 65 - 2.339 = 62.661
Upper boundary = 65 + 2.339 = 67.339

Consider the 30°-60° right triangle shown whose hypotenuse is equal to one. Clearly this triangle is half of an equilateral triangle. Please help me. Thank you! （╹◡╹）
Answer:
Step-by-step explanation:
Given triangle ABC is a right triangle.
m∠ACB = 60°
m∠CAB = 30°
m(AC) = 1 unit
A). Shorter side of the given triangle = Side BC
By applying cosine rule,
cos(∠C) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(60°) = [tex]\frac{BC}{AC}[/tex]
BC = [tex]\frac{1}{2}(AC)[/tex]
BC = [tex]\frac{1}{2}[/tex]
Length of the shorter side = 0.5 units
B). Longer side of the given triangle = side AB
By applying Pythagoras theorem in the given triangle,
AC² = AB² + BC²
1² = AB² + [tex](\frac{1}{2})^2[/tex]
1 = AB² + [tex]\frac{1}{4}[/tex]
AB = [tex]\sqrt{1-\frac{1}{4}}[/tex]
AB = [tex]\sqrt{\frac{3}{4}}[/tex]
AB = [tex]\frac{\sqrt{3} }{2}[/tex]
Length of the longer side = [tex]\frac{\sqrt{3}}{2}[/tex]

Give the exact answer in simplest form.
square miles
Answer:
4π mi²
Step-by-step explanation:

s = (135/360)(16) * π
s = 4π mi²
Bowler World charges $5.00 to rent shoes and $1.10 per game. Lucky Spares charges $3.00 for shoes and $1.50 per game.
Part A
Drag numbers to complete a system of equations to represent the situation, using g for number of games and c for cost. Numbers may be used once, more than once, or not at all.
Bowler World: c = _____g + ____
Lucky Spares: c =____ g + _____
We just need the equations to equal the same, which is y.
5+1.10x=y
3+1.50x=y
5+1.10x= 3+1.50x
Le'ts get x by itself by subtract 3 from both sides.
2+1.10x= 1.50x
Now subtract 1.10x from both sides.
2= 0.4x
Now divide each side by 0.4
5=X
So, at 5 games they're the same cost. Let's find the cost.
5+1.1(5)= 5+5.5=10.50
3+1.5(5)=3+7.5= 10.50
So, at 5 games, they are $10.50.
