Charges for advertising on a TV show are based on the number of viewers, which is measured by the rating. The rating is a percentage of the population of 110 million TV households. The CBS television show 60 Minutes recently had a rating of 7.8, indicating that 7.8% of the households were tuned to that show. An advertiser conducts an independent survey of 100 households and finds that at least b+1 were tuned to 60 Minutes. Assuming that the 7.8 rating is correct, find the probability of surveying 100 randomly selected households and getting at least 5+1 tuned to
60 Minutes.
The probability of surveying 100 randomly selected households and getting 4 or fewer tuned to 60 minutes is only 0.02%.
How to calculate the probabilityP(X <= 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)
P(X = k) = (100 choose k) * 0.078^k * (1 - 0.078)^(100-k)
P(X <= 4) = (100 choose 0) * 0.078^0 * (1 - 0.078)^(100-0) + (100 choose 1) * 0.078^1 * (1 - 0.078)^(100-1) + (100 choose 2) * 0.078^2 * (1 - 0.078)^(100-2) + (100 choose 3) * 0.078^3 * (1 - 0.078)^(100-3) + (100 choose 4) * 0.078^4 * (1 - 0.078)^(100-4)
Using a calculator or software, we can find that:
P(X <= 4) = 0.000203
This means that the probability is 0.02%.

In the figure, m<1= (3x+12)°, m<2= (3x+18)° and m<3= (7x+10)°. What is m<3?
The m<3 is approximately equal to 85.39 degrees.
The sum of the measures of the angles of a triangle is 180 degrees. So, we have:
m<1 + m<2 + m<3 = 180
So, (3x + 12) + (3x + 18) + (7x + 10) = 180
Simplifying and solving for x, we get:
13x + 40 = 180
13x = 140
x = 10.77
Now, we can find m<3 by substituting x in the expression for m<3:
m<3 = 7x + 10
m<3 = 7(10.77) + 10
m<3 = 85.39
Therefore, m<3 is approximately equal to 85.39 degrees.

A 5-foot wide
hallway requires
440.5 ft2 of carpet
to cover. How
long is the
hallway, in feet?
Answer:
length × width = area
440.5 = 5 × length
length = 440.5 / 5
length = 88.1
so haway is 88.1 foot long
the length of the hallway is 88.1 feet. To find the length of the hallway, we need to use the given information about the width of the hallway and the total area of the carpet required to cover it.
Given:
Width of the hallway = 5 feet
Area of carpet required = 440.5 ft^2
Let's denote the length of the hallway as "L" (in feet).
The area of a rectangle (such as the hallway) is given by the formula:
Area = Length * Width
In this case, the area is given as 440.5 ft^2, and the width is given as 5 feet. Now we can set up the equation:
440.5 = L * 5
To find the length (L), divide both sides by 5:
L = 440.5 / 5
L = 88.1
So, the length of the hallway is 88.1 feet.

figure 2-18 shows four paths along which objects move from a starting point to a final point, all in the same time interval. the paths pass over a grid of equally spaced straight lines
The ranking based on average speed is 1 > 2 > 4 > 3
(a) Based on the given information, we have:
V1 = V2: The objects on paths 1 and 2 have the same average velocity.
V3 < V4: The object on path 4 has a greater average velocity than the object on path 3.
(b) Average speed is simply the distance traveled divided by the time interval. If the objects move at a constant speed along each path, then the paths with the greatest distances will have the greatest average speeds. Therefore, the ranking based on average speed is:

Which Zeros of the polynomial function partially graphed below have even multiplicity?
The Zeros of the polynomial function partially graphed below have even multiplicity are x = -3 and x = 3.
What are the Zeros of the Polynomial?
The zeros of a Polynomial graph are simply the points where the graph curve crosses the x-axis.
In simply terms, the Zeros of a function are the values of the independent variable that make the function equal to 0. Multiplicity just refers to how many copies of a given zero exist.
From the given graph, the zeros of the Polynomial function are x = 2 and x = 3 and x = -3
An odd multiplicity means the graph of the function crosses the x-axis at that point. An even multiplicity means the curve contacts the x-axis at that point and backs instead of crossing.
Thus, the odd multiplicity is at x = 3

\(6/5 (cos(120) + isin(120)) 3/5 (cos(45) + i sin(45))\)
The product is equal to:
\(\frac{18}{25}(cos(165) + i*sin(165))\)
How to solve the product?Remember that we can write a complex number in polar form as:
\(R*e^{i*a} = R*(cos(a) + i*sin(a))\)
Then the given product:
\(\frac{6}{5}*(cos(120) + i*sin(120))*\frac{3}{5}*(cos(45) + i*sin(45))\)
can be rewritten to:
\((\frac{6}{5}*e^{i*120})*(\frac{3}{5}*e^{i*45})\)
Now is easier to solve the product:
\((\frac{6}{5}*e^{i*120})*(\frac{3}{5}*e^{i*45})\\\\= \frac{6}{5} *\frac{3}{5} *e^{i*(120 + 45)}\\\\= \frac{18}{25}*e^{i*165}\\\\= \frac{18}{25}(cos(165) + i*sin(165))\)

Jeremy's coach makes him run clockwise around a circular track with radius of 50 meters. Jeremy manages to maintain a constant speed around the track. He takes 48 seconds to finish one lap of the track. From his starting point, it takes him 12 seconds to reach the northernmost point of the track. Answer the following questions below assuming that the center of the track at the origin and the northernmost point is on the y-axis.
a. Give Jeremy's coordinates at his starting point.
b. Give Jeremy's coordinates when he has been running for 4 seconds.
c. Give Jeremy's coordinates when he has been running for 32 seconds.
Answer:
Coordinates of the starting point ( -50 ; 0 )
Coordinates 4 seconds later Q ( - 25*√3 ; 25 )
Coordinates 32 seconds later R ( 25 ; - 25*√3 )
Step-by-step explanation:
a) If Jeremy takes 48 seconds fr a lap then
The length of the lap ( length of the circle ) is:
L = 2*π*r ⇒ L = 100*π
If the time for one lap was 48 seconds at a constant speed, the speed was
v = 100*π / 48 [m/s]
v = 6,54 m/s
12 seconds is 1/4 0f 48 in that time he (she) reach the northernmost point, then he(she) necessarily started on the negative side of the x-axis the coordinates at this point are
( -50 ; 0 )
b) 4 seconds later, at v = 6,54 m/s by rule of three
In 12 seconds 90⁰
In 4 seconds (the third part ) x ??
x = 30⁰
sin 30⁰ = 1/2
cos 30⁰ = (√3)/2
And coordinates for the point are
sin 30⁰ = 1/2 = y/50 ⇒ y = 25
cos 30⁰ = (√3)/2 = x / 50 ⇒ x = 25*√3
coordinates of the point 4 seconds later
Q ( - 25*√3 ; 25 ) she (he) is in the negative part of x-axis
c) 32 seconds later
32 is 12 + 12 + 8
Then she (he) is 8 seconds below the positive side of x-axis
8 is 2/3 of 12 ( negative 60⁰ )
sin 60⁰ = (√3)/2 = y/50 y = 25*√3 negative
cos 60⁰ = 1/2 * 50 = X/50 x = 25
Coordinates of the point R

The coordinates of vertex D in the parallelogram are (-7, -10).
We have,
To find the coordinates of vertex D of the parallelogram, we need to use the properties of a parallelogram.
One of these properties states that opposite sides of a parallelogram are parallel and have equal lengths.
Given that A = (8, 2), B = (6, -4), and C = (-5, -4), we can find the coordinates of D as follows:
Find the vector representing one of the sides of the parallelogram.
We can use the vector AB.
Vector AB = (x-coordinate of B - x-coordinate of A, y-coordinate of B - y-coordinate of A)
= (6 - 8, -4 - 2)
= (-2, -6)
Add this vector to point C to find the coordinates of D.
Coordinates of D = (x-coordinate of C + x-coordinate of AB, y-coordinate of C + y-coordinate of AB)
= (-5 - 2, -4 - 6)
= (-7, -10)
Therefore,
The coordinates of vertex D are (-7, -10).
