Solving a linear equation, we will see that 109 attendees did not visit the concession stand.
How to find the number of attendees who did not visit the concession stand?
First, we know that the total number of surveyed people is 680.
Of these 680, we know that:
527 said that the concession stand prices are excessive.44 said that the concession stand prices are not excessive.x did not visit the concession stand.Now, the 3 numbers above should add up to the total number of surveyed people.
527 + 44 + x = 680
Solving that linear equation for x:
x = 680 - 527 - 44 = 109
We conclude that the number of attendees who did not visit the concession stand is 109.

Beth is making a beanbag seat in the shape of a cube. Each side of the seat is 2 feet long. Beth needs to find the volume of the seat so that she can buy the correct amount of bean. Beans are sold in bags that hold 2 cubic feet of beans. How many bags should Beth buy?
With the help of the volume of cube it is concluded that Beth should buy 4 bags of beans.
What Is Volume of Cube?The volume of a cube is the total three-dimensional space that it occupy. A cube's volume is expressed as cubic units. The SI unit of volume is the cubic meter [tex](m^3)[/tex], which is the volume occupied by a cube with each side measuring 1 m.
The first thing to do in this case is to find the volume of the cube, which will be given by:
V = [tex]L ^ 3[/tex]
where, L = sides of the cube.
Substituting we have:
V = [tex](2) ^ 3[/tex]
V = [tex](8) ^ 3[/tex]
Since, beans are sold in bags that hold two cubic feet of beans.
Now, to find the number of bags, we calculate

A new highway has just opened and tolls will be collected from vehicles using the highway. The toll will be 119 cents for cars which travel 20 miles of the
highway. The toll will be 184 cents for cars which travel 33 miles of the highway. Let T(d) be a function which gives the total toll (in cents) which will be
charged to a car which travels d miles along the highway. Assume T(d) is a linear function. Find T'(d).
T(d) =
What will be the toll to travel 96 miles?
cents
Answer:
T(d) = 5d +19T(96) = 499 . . . centsStep-by-step explanation:
Given two points on the linear toll function T(d) are (20, 119) and (33, 184), you want the equation for the function T(d), and the value of T(96).
SlopeIt is usually convenient to write the equation of a line in slope-intercept form when you want to find the value at a particular point. To use that form, we need to know the slope of the line. It is given by the formula ...
m = (y2 -y1)/(x2 -x1)
Using the given points, we have ...
m = (184 -119)/(33 -20) = 65/13 = 5
Point-slope equationThe point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
Using the first point and the slope we found, the equation is ...
y -119 = 5(x -20)
Slope-intercept equationSolving the above equation for y, we get ...
y = 5x -100 +119 . . . . . . . simplify, add 119
y = 5x +19 . . . . . . . . . . combine terms
Using variables d and T instead of x and y, the function is ...
T(d) = 5d +19
Toll for 96 milesThe value T(96) is ...
T(96) = 5(96) +19 = 480 +19 = 499
The toll for 96 miles is 499 cents.

In a survey of 400 households regarding ownership of HDTVs and DVD players, the following data were obtained. 315 households own one or more HDTVs. 150 households own one or more HDTVs and one or more DVD players. 16 households do not own an HDTV or a DVD player. How many households only own one or more DVD players?
Number of households only own one or more DVD players = 219
Total number of households considered for the survey = 400
Let n(A) represent the number of households only own one or more HDTVs.
Then n(A) = 315
Let n(B) denotes the number of households only own one or more DVD players. We need to find n(B).
Number of households own one or more HDTVs and one or more DVD players, n(A∩B) = 150
Number of households do not own an HDTV or a DVD player = 16
So the number of households which own an HDTV or a DVD player, n(A∪B) = 400 - 16 = 384
Then we have the formula relating n(A∪B), n(A), n(B) and n(A∩B).
n(A∪B) = n(A) + n(B) - n(A∩B)
⇒ n(B) = n(A∪B) - n(A) + n(A∩B)
= 384 - 315 + 150
= 219
The number of households only own one or more DVD players = 219

The slope of Parallel Lines:
Slopes of parallel lines are equal. The parallel lines are equally inclined with the positive x-axis and hence the slope of parallel lines is equal. If the slopes of two parallel lines are represented as m1, m2 then we have
In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.
The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.
Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,
m = change in y/change in x = Δy/Δx
Where “m” is the slope of a line.
The slope of the line can also be represented by
tan θ = Δy/Δx
So, tan θ to be the slope of a line.
Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘m’
m1 = m2.
y 2/3 = x + 1 ...1
2y = 3x+3
y = 3/2x +3/2
m1= 3/2
x,y = -6,-1
y = mx +b
(y-y1 ) =m (x-x1) +b
m1=m2
m2= 3/2
(y +1) = 3/2 (x+6)
2(y+1 )= 3x+18

A produce packing company prepares crates of apples to ship to supermarkets. Suppose
that the weight of a randomly selected crate is known to be Normally distributed, with
a mean of 14 kg and a standard deviation of 1.4 kg.
(a) Find the weight of a particular crate such that the probability of randomly selecting a heavier crate is 0.05.
(b) Find the probability that a randomly selected crate will weigh more than 16kg.
(c) If 20 crates are randomly and independently selected, what is the probability that
at least 2 of them will weigh more than 16kg?
a. The weight of a particular crate such that the probability of randomly selecting a heavier crate is 0.05 is 16.30kg.
b. The probability that a randomly selected crate will weigh more than 16kg is 0.0764.
c. The probability that.at least 2 of them will weigh more than 16kg is 0.4584.
How to calculate the probability?a. From the information, there is a mean of 14 kg and a standard deviation of 1.4 kg. The weight will be:
Let the weight = x
X = (Z × mean × standard deviation)
= (1.645 × 1.4 ×14)
= 16.30kg
b. The probability that a randomly selected crate will weigh more than 16kg will be:
P(z > 16)
= P(Z > 16-14/1.40)
= P(Z > 1.43)
Looking under the normal distribution table, the value is 0.0764.
c. The probability that at least 2 of them will weigh more than 16kg when 20 crates are randomly and independently selected will be through binomial distribution where n = 20 and p = 0.0764.
This will give a value of:
= 1 - 0.5416
= 0.4584
Therefore, the probability that.at least 2 of them will weigh more than 16kg is 0.4584.

Put in scientific notation and explain how it works.
Answer:
3.9 x [tex]10^{8}[/tex]
Step-by-step explanation:
0.39 is not in scientific notation. For a number to be in scientific notation the first factor has to be 1 or greater, but less then 10. 0.39 is less than one.
First we must write 0.39 in scientific notation. We need to move the decimal so that the number is greater than 1, but less than ten. If we move the decimal one place to the right, we get 3.9. The standard number is smaller than 3.9. How much smaller? [tex]10^{-1}[/tex] smaller.
0.39 in scientific notation would be 3.9 x [tex]10^{-1}[/tex]. We cannot forget the [tex]10^{9}[/tex], so our number looks like this now:
3.9 x [tex]10^{-1}[/tex] x [tex]10^{9}[/tex] The product of powers principle tells us that if we have powers with the same bases, we can add the exponents.
3.9 x [tex]10^{-1+9}[/tex]

If the measure of angle 2=a+15 and the measure of angle 3=a+35, find a if HL is perpendicular to HJ
The value of a if HL is perpendicular to HJ is 20
How to determine the value
From the information given, we have that;
HL = angle 2 = a + 15HJ = angle 3 = HJIt is important to note that perpendicular lines always intersect each other and the angle between perpendicular lines is equivalent to 90 degrees.
Then, we have that;
Angle 2 + angle 3 = 90 degrees
Substitute the values
a + 15 + a + 35 = 90
collect like terms
2a + 50 = 90
2a = 90 - 50
subtract like terms
2a = 40
Make 'a' the subject
Divide both sides by 2
2a/2 = 40/2
a = 20
Thus, the value of a if HL is perpendicular to HJ is 20
