Question 8, 11.1.21 A stock can go up, go down, or stay unchanged. How many possibilities are there if you own 9 stocks?
Explanation:
Consider 2 stocks that either go up, down, or stay unchanged. We'd have a 3 by 3 table to show the 3*3 = 3^2 = 9 different outcomes.
This idea can be extended to 3 stocks to have 3*3*3 = 3^3 = 27 outcomes
4 stocks would have 3^4 = 81 outcomes and so on
Therefore, 9 stocks have 3^9 = 19683 outcomes
In 1920, the record for a certain race was 46.4 sec. In 1970, it was 45.4 sec. Let R(t)=the record in the race and t= the number of years since 1920.
a) Find a linear function that fits the data.
b) Use the function in (a) to predict the record in 2003 and in 2006.
c) Find the year when the record will be sec.
The year will be 2018, the predicted record of 43.74
1920, the record for a certain race was 45.9 sec.
In 1950, it was 45.0 sec.
Let R(t)= the record in the race and t= the number of years since 1920.
How to calculate slope
The equation of slope of any line can be calculated using the following formula, m = rise/run = tanθ = Δy/Δx = (y2 - y1)/(x2 - x1) where, m is the slope. Δy is the change in y-coordinates.
slope = (45-45.9)/30 = -0.9/30 = -0.03
EQUATION:
R(t)= -0.03t + 45.9
b) The predicted record for 2003
t = 83 in 2003
R(83) = -0.03*83 + 45.9
R(83) = 43.41
The predicted record for 2006
t = 86 in 2006
R(86) = -0.03*86 + 45.9
R(86) = 43.32
C) Solve for t
-.02t + 45.7 = 43.74
-.02t = 43.74 - 45.7
-.02t = -1.96
t = +98
1920 + 98 = 2018, the predicted record of 43.74
This type of equations are called linear equations
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it.

The coordinates of triangle MNP and triangle QRS are shown in the table.
Triangle MNP
Triangle QRS
M(2, 5) N(6, 4) P(6, 8)
Q(–2, -5) R(–6, -4) S(–6, -8)
Which BEST describes the relationship, in terms of congruency, between triangle MNP and triangle QRS?
Using translation concepts, it is found that the triangles are congruent, as triangle QRS is the result triangle after a 180º rotation about the origin of triangle MNP.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis, or rotations of a degree measure around the origin.
From the vertices of the triangles MNP and QRS, the following transformation was applied:
(x,y) -> (-x,-y).
Which is a 180º rotation about the origin, that is, triangle QRS is the result triangle after a 180º rotation about the origin of triangle MNP.
Rotations do not change the side lengths, only the orientation of the triangle, hence the triangles QRS and MNP are congruent.

Answer: 2 pairs
Step-by-step explanation: You can tell which angles are congruent based on the curved markings. Pairs of congruent angles have matching markings. Since two of the angles are congruent to each other, we can assume that the third angles on the triangles are also congruent to each other, but it is not marked as such. So, there are only two marked pairs of congruent angles.

You buy a carton of milk and two sandwiches for $10.One sandwich costs twice as much as a carton of milk.Your friend buys two cartons of milk and three sandwiches. How much does your friend spend?
The total amount spent by your friend is $8
How to determine the amount spent by your friend?The given parameters are:
1 carton of milk and 2 sandwiches= $10The cost of 1 sandwich = Twice carton of milkRepresent sandwich with x and carton of milk with y
So, we have
x = 2y
This also means that
y + 2x = 10
Substitute x = 2y in y + 2x = 10
y + 2(2y) = 10
This gives
5y = 10
Divide by 2
y = 2
Recall that:
x = 2y
So, we have
x =2 * 1
x = 2
Your friend's purchase can be represented as:
2y + 3x
This gives
Total = 2 * 1 + 3 * 2

Using relations in a right triangle, it is found that the angle of depression from the satellite to the horizon is of 89.35º.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.First, we consider that:
The opposite side to the internal angle at the satellite is of 4000 mi.The hypotenuse is of 4000 mi + d mi = 17500 mi.Hence the sine of the angle is given as follows:
sin(θ) = 4000/175000
θ = arcsin(4000/175000)
θ = 1.31º.
Twice the angle of depression x and θ are supplementary, hence:
2x + 1.31 = 180
2x = 178.69.
x = 178.69/2
x = 89.35º.
The angle of depression from the satellite to the horizon is of 89.35º.

1-131. Lindsay has a paper bag full of Fruiti Tutti Chews in three different fruit flavors. She says, “If you reach into the bag, you have a chance of pulling out a Killer Kiwi. There is a chance that you will get Crazy Coconut.”
The probability of choosing a Kiwi or a coconut is 14/15.
There has to be another flavor in the bag. The probability of picking the third flavor is 1/15.
There can be 15 candies in the bag. There can be more than one possibility.
What is the probability?Probability calculates the odds that a random event would occur. The odds that the random event happens lie between 0 and 1. The more likely the event is to occur, the closer the probability value is to 1. If the probability value is 0.5, it is equally likely and unlikely that the event would happen or not happen. The sum of all probabilities should add up to 1.
The probability of choosing a Kiwi or a coconut = chances of picking a kiwi + chances of picking a coconut
1/3 + 3/5
(5 + 9) / 15 = 14/15
There has to be another flavor in the bag because the sum of the probabilities of picking a coconut or a kiwi does not add up to 1.
The probability of getting another flavor = 1 - sum of the probabilities of picking a kiwi or a coconut
1 - 14/15
15/15 - 14/15 = 1/15
The total number of candies in the bag would be a multiple of 15. The multiple of a number is the product of the number and another number. The possible number of candies are 15, 30, 45, 60, 75, 90
