Aniela took 10 pages
of notes over the span of 4
classes. If Aniela worked at a
constant rate, how many notes
did she take in one class?
Answer: Aniela took 2.5 pages of notes per class
Step-by-step explanation: If you take the total amount of pages of notes taken and divide it by the number of classes you get the rate of pages of notes per class. So 10 pages/4 classes = 2.5 pages/class

e table shows ordered pairs of the function . What is the value of y when ? A 2-column table with 6 rows. The first column is labeled x with entries negative 3, negative 1, 1, 4, 8, 10. The second column is labeled y with entries 14, 10, 6, 0, question mark, negative 12. –20 –8 8 48
y = -8.
An ordered pair is a composition of the x coordinate and the y coordinate, having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension.
Ordered pairs are often used to represent two variables. When we write (x, y) = (7, - 2), we mean x = 7 and y = - 2. The number which corresponds to the value of x is called the x-coordinate and the number which corresponds to the value of y is called the y-coordinate.
see attachment for the table
we observe from the given table that
As x increases by 2, y decreases by 4
As x decreases by 2, y increases by 4
for example x = 10, y = -12
when x decreases by 2 (to 8), the value of y will increase by 4 (to -8).
Hence, the value of y when x = 8 is -8

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.

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

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

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.

The equation C= 8h+25 represents the cost in dollars, C, to rent a canoe, where h is the number of hours the canoe is rented.
What is the cost to rent a canoe for 4 hours?
The cost to rent a canoe for 4 hours is $57.
How to calculate the cost?It should be noted that the equation given is illustrated as equation C= 8h+25 represents the cost in dollars, C, to rent a canoe.
C = 8h + 25.
where h = number of hours
C = 8h + 25

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

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
