Answer:
the number of ways in which the prizes are allocated is 67,525
Step-by-step explanation:
Given that
Number of customers = 75
Number of prizes = 3
And, the value of gift card = $10
Based on the above information,
The number of ways in which the prizes are allocated is shown below:
[tex]=^{75} C_3[/tex]
= [tex]\frac{75!}{(3!\times(75-3)!}[/tex]
After solving this the number of ways that came is 67,525
hence, the number of ways in which the prizes are allocated is 67,525

Step-by-step explanation:
suppose Q is the midpoint of PR. use the information to find the missing value. PQ equals 3x + 14 and QR equals 7X - 10; find X.
Answer:
x=6
Step-by-step explanation:
A midpoint is the middle point of a line segment, therefore it is equal distances from both ends of the segment.
This means that PQ and QR have the same length. So all we have to do is set each value equal to each other, and then solve for X.
[tex]3x+14=7x-10\\3x+24=7x\\24-4x\\x=6[/tex]
Answer:
x=-0.4
Step-by-step explanation:
ok you have to visualize this line
P Q R
O---------------------O-----------------------O
3x+14 7x-10
so to make the equation of PR you would add PQ and QR together.
3x+14+7x-10
add your like terms
10x+4
solve for x
10x+4=0
subtract 4 from each side
10x=-4
divide both sides by 10
x=-2/5 fraction
x=-0.4 decimal

What is the upper bound of the function f(x)=4x4−2x3+x−5?
Answer:
(no global maxima found)
Step-by-step explanation:
Find and classify the global extrema of the following function:
f(x) = 4 x^4 - 2 x^3 + x - 5
Hint: | Global extrema of f(x) can occur only at the critical points or the endpoints of the domain.
Find the critical points of f(x):
Compute the critical points of 4 x^4 - 2 x^3 + x - 5
Hint: | To find critical points, find where f'(x) is zero or where f'(x) does not exist. First, find the derivative of 4 x^4 - 2 x^3 + x - 5.
To find all critical points, first compute f'(x):
d/( dx)(4 x^4 - 2 x^3 + x - 5) = 16 x^3 - 6 x^2 + 1:
f'(x) = 16 x^3 - 6 x^2 + 1
Hint: | Find where f'(x) is zero by solving 16 x^3 - 6 x^2 + 1 = 0.
Solving 16 x^3 - 6 x^2 + 1 = 0 yields x≈-0.303504:
x = -0.303504
Hint: | Find where f'(x) = 16 x^3 - 6 x^2 + 1 does not exist.
f'(x) exists everywhere:
16 x^3 - 6 x^2 + 1 exists everywhere
Hint: | Collect results.
The only critical point of 4 x^4 - 2 x^3 + x - 5 is at x = -0.303504:
x = -0.303504
Hint: | Determine the endpoints of the domain of f(x).
The domain of 4 x^4 - 2 x^3 + x - 5 is R:
The endpoints of R are x = -∞ and ∞
Hint: | Evaluate f(x) at the critical points and at the endpoints of the domain, taking limits if necessary.
Evaluate 4 x^4 - 2 x^3 + x - 5 at x = -∞, -0.303504 and ∞:
The open endpoints of the domain are marked in gray
x | f(x)
-∞ | ∞
-0.303504 | -5.21365
∞ | ∞
Hint: | Determine the largest and smallest values that f achieves at these points.
The largest value corresponds to a global maximum, and the smallest value corresponds to a global minimum:
The open endpoints of the domain are marked in gray
x | f(x) | extrema type
-∞ | ∞ | global max
-0.303504 | -5.21365 | global min
∞ | ∞ | global max
Hint: | Finally, remove the endpoints of the domain where f(x) is not defined.
Remove the points x = -∞ and ∞ from the table
These cannot be global extrema, as the value of f(x) here is never achieved:
x | f(x) | extrema type
-0.303504 | -5.21365 | global min
Hint: | Summarize the results.
f(x) = 4 x^4 - 2 x^3 + x - 5 has one global minimum:
Answer: f(x) has a global minimum at x = -0.303504
What is the rate of change for the points (0,3) and (2,7)
Answer:
2
Step-by-step explanation:
The rate of change in function f(x) from x = a to x = b is (f(b) - f(a))/(b - a).
rate of change = (7 - 3)/(2 - 0) = 4/2 = 2
Answer:
rate of change = 2 unit rise per 1 unit run
Step-by-step explanation:
The rate of change of two points on a graph is represented by the slope of a line connecting the two points.
here we are given the coordinates of the two points, hence we can simply apply the slope formula for a line given two points (see attached)
for points (0,3) and (2,7)
x₁ = 0, y₁ = 3, x₂ = 2, y₂ = 7
substituting these into the formula
rate of change
= slope, m
= (y₂-y₁) / (x₂-x₁)
= (7 - 3) / (2 - 0)
= 4 / 2
= 2
3. Your friend is having trouble deciding which shirt, tie, and pair of pants to wear to
his school's formal dance. He has 4 shirts, 3 pairs of pants, and 4 ties. How many
total possible outfits can be created?
64 outfits
16 outfits
48 outfits
12 outfits
Answer: 4 shirts x 3 pairs of pants x 4 ties = 4 x 3 x 4=48
so there are 48 possibilities (option 3)

Find p(4) and p(-2) for each function.
p(x) = x² – 3x + 8
Answer:
p(x)=x2 - 3x + 8
p(4) =(4)2 - 3(4) + 8
= 16 - 12 + 8
= 4+8
= 12
p(-2)= (-2)2 - 3(-2) + 8
= 4+6+8

I know it’s a lot but I need help didn’t get the material because I’m doing online classes and my WiFi is trash
Answer: not sure if that is a b but i beleive it is so
bh+hr=25
move all terms to the left side and set equal to 0. then set each factor equal to zero.
h= [tex]\frac{25}{b+r}[/tex]
isolate the variable by dividing each side by factors that dont
contain the variable.
r=[tex]\frac{25}{h}-b[/tex]
x=[tex]\frac{r-h}{y}[/tex]
isolate the variable by dividing each side by factors that dont
contain the variable.
h=-xy+r
solve for r by simplifieng both sides of the equation, then isolating the variable.
r=xy+h
Answer:
1A. h = 25/(b + r)
1B. r = 25/h - b
2A. h = r - xy
2B. r = xy + h
Step-by-step explanation:
1. bh + hr = 25
A. h(b + r) = 25
h = 25/(b + r)
B. h(b + r) = 25
b + r = 25/h
r = 25/h - b
2. x = (r - h)/y
A. xy = r - h
h + xy = r
h = r - xy
B. xy = r - h
r = xy + h
BC = 12 and AB = 11. Find AC.
Answer:
AC = 23
Step-by-step explanation:
Assuming A, B, and C are on a line with B in the middle...
We know that AB + BC = AC. Travelling from A to C is the same as travelling from A to B, then B to C, as B is on the way between A and C.
Knowing this, we can set up this equation and add the 2 numbers we know:
AC = AB + BC
AC = 11 + 12
AC = 23
-Is ZFDE a possible name for the figure below? Explain.
E
D
F
It’s number 14
Answer: Yes [tex]\angle FDE[/tex] is one possible angle name
Another name is [tex]\angle EDF[/tex]
When it comes to naming an angle this way, all we need to worry about is the vertex point. This is where the angle hinges (think of a door or a pair of scissors). In this case, the hinge or vertex point is at point D. The vertex is always the middle letter of any three-letter sequence. The order of the other two points does not matter.
This is why saying "angle FDE" is the same as "angle EDF".
How do I solve this ?
Answer:
Step-by-step explanation:
I'm just going to go out on a limb here and assume that those are a set of poorly made parenthesis. This, then, would be your equation:
[tex]x+\frac{x}{7}+\frac{1}{11}(x+\frac{x}{7})=60[/tex]
The first thing to do is distribute through the parenthesis to get:
[tex]x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60[/tex]
Next is to get rid of the denominators by multiplying by the LCM of 77:
[tex]77(x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60)[/tex] which gives you:
77x + 11x + 7x + x = 4620 and
96x = 4620 so
[tex]x=\frac{385}{8}[/tex]

3. What is the volume of the triangular
prism?
Answer:
C. 51,84
Step-by-step explanation:
the volume of the triangular prism is 1/2*3.2*5.4*6
Answer:
C
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = Al ( A is the area of the triangular end, l is the length )
A = [tex]\frac{1}{2}[/tex] bh ( b is the base, h the perpendicular height )
Here b = 5.4 and h = 3.2 , thus
A = 0.5 × 5.4 × 3.2 = 8.64 cm² , then
V = 8.64 × 6 = 51.84 cm³ → C

Find the midpoint: (-1, 9), (7, -1)
Answer: (3,4)
Step-by-step explanation:
To find the midpoint, you want to use the formula [tex]m=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]. Since we are given the two points, we can plug them in and solve.
[tex]m=(\frac{-1+7}{2} ,\frac{9+(-1)}{2} )[/tex] [add numerator]
[tex]m=(\frac{6}{2} ,\frac{8}{2} )[/tex] [divide]
[tex]m=(3,4)[/tex]
Now, we know that the midpoint is (3,4).

Answer:
x = 35°, Angle 1 = 145°, Angle 2 = 35°
Step-by-step explanation:
In a trapezoid, the angles on the same leg are supplementary, meaning they add up to 180°. That means Angle 2 plus Angle 1 equals 180°. Therefore:
[tex](4x+5)+x=180^{\circ}\\5x+5=180^{\circ}\\5x=175^{\circ}\\x=35^{\circ}[/tex]
Therefore, x = 35°, Angle 2 = 35°, and Angle 1 =
[tex]4x-5^{\circ}\\4(35^{\circ})+5^{\circ}\\140^{\circ}+5^{\circ}=145^{\circ}[/tex]
To ensure our answers make sense, we verify they equal 180°:
