Answer: The area of the triangle is 25 units^2.
Step-by-step explanation: The formula to find the area of the triangle is (base * height)/2. In this case, the base is 10 units long (on the x axis, it's the overall horizontal length of the triangle) and the height is 5 units long (the height can be calculated by finding the y axis length from the highest point of the triangle to the lowest). So (10*5)/2 = 50/2 which equals 25. And keep in mind, because this is the area, the unit will be units squared.

You agree to purchase a home for $200,000 and decide to make a 20% down payment on the home. You finance the rest of the home payment with a 15 year fixed rate mortgage with an annual interest rate of 5.25%. Assuming that you make regular monthly payments, determine your regular monthly payment amount. Provide just a numerical answer rounded to the nearest cent.
Answer:
a or 1. $40,000 is the down payment
b or 2. 180 months = 15 years
c or 3. $168,400 is the left over payment (including mortgage)
d or 4. $935.56 (the monthly payment)
Step-by-step explanation:
1. To calculate the down payment, we need to calculate 20% of $200,000.
200,000 x 0.20 = $40,000
Therefore, the down payment on the home costs $40,000.
2. Now, let's figure out how many months are in 15 years.
15 x 12 = 180
So, the mortgage will be paid in 180 months.
3. Next, we need to find out how much money needs to be paid in the 15 years.
200,000 - 40,000 = $160,000
This price will also include an annual interest rate of 5.25%. So, we need to find 5.25% of $160,000.
160,000 x 0.0525 = $8,400 <--- interest rate when rounded to the nearest cent.
160,000 + 8,400 = $168,400 <--- total amount over 15 years
4. To find the monthly payment, we must divide the total amount of money ( or $168,400), by the number of months, (or 180.)
$168,400 ÷ 180 = $935.56 when rounded to the nearest cent.

Question 1 of 10
Multiple Choice
Identify if first number is divisible by the second number, and if so, the reason why.
Is 26 divisible by 2?
A.
No
B.
Yes, because 2 + 6 = 8 and 8 is divisible by 2.
C.
Yes, because the last digit is 6, which is divisible by 2.
Simplify using the distributive property.
10 - 2(x - 7) = 4(x - 5)
24 - 2 x = 4 x - 20
-4 - 2 x = 4 x - 5
3 - 2 x = 4 x + 5
Answer:x=22 over 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10−2(x−7)=4(x−5)
10+(−2)(x)+(−2)(−7)=(4)(x)+(4)(−5)(Distribute)
10+−2x+14=4x+−20
(−2x)+(10+14)=4x−20(Combine Like Terms)
−2x+24=4x−20
−2x+24=4x−20
Step 2: Subtract 4x from both sides.
−2x+24−4x=4x−20−4x
−6x+24=−20
Step 3: Subtract 24 from both sides.
−6x+24−24=−20−24
−6x=−44
Step 4: Divide both sides by -6.
−6x−6=−44−6
x=22 over 3

Assume that Jim, Bruce, and Valerie are three of the 19 members of the class, and that three of the class members will be chosen randomly to deliver their reports during the next class meeting. What is the probability that Jim, Bruce, and Valerie are selected in any order?
Answer:
[tex]Probability = \frac{1}{969}[/tex]
Step-by-step explanation:
Given
[tex]Members = 19[/tex]
[tex]Selection = 3[/tex]
Required
Determine the probability of selecting Jim, Bruce and Valerie
First, we need to calculate the possible number of selections.
This is calculated using combination formula:
[tex]Selection = ^nC_r[/tex]
[tex]Selection = ^{19}C_3[/tex]
[tex]Selection = \frac{19!}{(19-3)!3!}[/tex]
[tex]Selection = \frac{19!}{16!3!}[/tex]
[tex]Selection = \frac{19 * 18 * 17 * 16!}{16! * 3 * 2 * 1}[/tex]
[tex]Selection = \frac{19 * 18 * 17}{3 * 2 * 1}[/tex]
[tex]Selection = \frac{19 * 18 * 17}{6}[/tex]
[tex]Selection = 969[/tex]
Selection of Jim, Bruce and Valerie is only 1 selection of the 960 possible selection.
So:
[tex]Probability = \frac{1}{969}[/tex]
The probability that Jim, Bruce, and Valerie are selected in any order is [tex]\rm P=\dfrac{1}{969}[/tex] and this can be determined by using the given data.
Given :
Assume that Jim, Bruce, and Valerie are three of the 19 members of the class and that three of the class members will be chosen randomly to deliver their reports during the next class meeting.
In order to determine the probability that Jim, Bruce, and Valerie are selected in any order, first determine the total number of possible selections.
The total number of possible selections is given by:
[tex]\rm S = \; ^nC_r[/tex]
[tex]\rm S = \; ^{19}C_3[/tex]
[tex]\rm S = \dfrac{19!}{16! \times 3!}[/tex]
S = 969
So, the probability that Jim, Bruce, and Valerie are selected in any order is:
[tex]\rm P=\dfrac{1}{969}[/tex]

Courtney makes 80 % 80%80, percent of the free throws she attempts. She often stays after practice to shoot sets of 10 1010 free throws. Assume that the results of free throws are independent from each other. What are the mean and standard deviation of the number of free throws she makes in each set of 10 1010?
Answer:
Mean: 8 free throws
Standard Deviation: 1.3 free throws
Step-by-step explanation:
This is a binomial random variable, so we can use the formula [tex]ux = np[/tex], where n is the number of trials, and p is the probability. Since we know both of these values, just plug it in for the mean. [tex]ux = .8*10 = 8[/tex]
For the standard deviation, we use the formula σ = [tex]\sqrt{np(1-p)}[/tex]. Since we know what np is, we can replace those 2, giving us [tex]\sqrt{8(1-p)}[/tex]. Again, p is our probability, so this gives us our final equation of [tex]\sqrt{8(1-.8)}[/tex], which simplifies to [tex]\sqrt{8(.2)}[/tex]. Using a calculator, we get 1.264, which is 1.3 rounded to the nearest tenth.

Answer:
S(-2, -3)
Step-by-step explanation:
Find the diagram attached below,=. Frim the diagram, the coordinate of R and T are (-5, 3) and (-1, -5) respectively. If the ratio of RS to ST is 3:1, the coordinate of S can be gotten using the midpoint segment formula as shown;
S(X, Y) = {(ax1+bx2/a+b), (ay1+by1/a+b)} where;
x1 = -5, y1 = 3, x2 = -1, y2 = -5, a = 3 and b =1

what positive whole number can you multiply by 3 and add1,or multiply by 2 and add 8?
Answer:
7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.
Step-by-step explanation:
Multiplying the positive whole number 7 by 3 and adding 1 will get:
(7 × 3) + 1 = 21 + 1 = 22
Multiplying the positive whole number 7 by 2 and adding 8 will get:
(7 × 2) + 8 = 14 + 8 = 22
Therefore, 7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.
The graph of g is a vertical shrink by a factor of 1/3 and a reflection in the y-axis, followed by a translation 3 units right of the graph of f(x)=x2. Write a rule for g.
Answer: g(x) = (1/3)*(-x)^2 + 3.
Step-by-step explanation:
Let's define all the transformations in a general way,
A vertical contraction/dilation of a scale factor a is written as:
g(x) = a*f(x)
where if a > 1, it is a dilation.
if 0 < a < 1, it is a contraction.
A reflection in the y-axis changes the value of the x-component and leaves the y-component invariable, then this transformation is written as:
g(x) = f(-x).
A translation of A units up (A positive) is written as:
g(x) = f(x) + A.
Then for this case we have:
A dilation with scale factor 1/3.
g(x) = (1/3)*f(x)
A reflection over the y-axis.
g(x) = (1/3)*f(-x)
A translation of 3 units up.
g(x) = (1/3)*f(-x) + 3
(in that order, remember that the order in which you applly the transformations matters)
Then g(x) = (1/3)*f(-x) + 3
and f(x) = x^2, so we can replace that in the equation for g(x)
g(x) = (1/3)*(-x)^2 + 3.
Transformation involves changing the position of a function.
The rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]
The parent function is given as:
[tex]\mathbf{f(x) = x^2}[/tex]
The rule of vertical shrink by a factor of 1/3 is:
[tex]\mathbf{(x,y) \to (x,\frac 13y)}[/tex]
So, we have:
[tex]\mathbf{f'(x) = \frac 13x^2}[/tex]
The rule of reflection across the y-axis is:
[tex]\mathbf{(x,y) \to (-x,y)}[/tex]
So, we have:
[tex]\mathbf{f''(x) = \frac 13(-x)^2}[/tex]
[tex]\mathbf{f''(x) = \frac 13x^2}[/tex]
The rule of translation 3 units right is:
[tex]\mathbf{(x,y) \to (x - 3,y)}[/tex]
So, we have:
[tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]
Hence, the rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

Lesson: Word problems involving quadratic and rational equations
Answer: the larger number is 54
Step-by-step explanation:
x + y = 56
xy = 108
x = 56 - y
substitute the x value in equation
(56 -y) y = 108
56y - y^2 = 108
y^2 - 56y + 108 = 0
=(y - 2)(y - 54)
The two numbers are 2 and 54.
What is multiplication?Multiplication is the process of adding a number up to a given number.
Given that, the sum of the two numbers is 56 and their product is 108.
Let the numbers are x and y then,
x + y = 56 (1)
xy = 108
x = 108/y
Substitute x = 108/y into equation (1):
108/y + y = 56
108 + y² = 56y
y² -56y + 108 = 0
y² -54y -2y + 108 =0
y(y - 54) -2(y - 54) = 0
(y - 2)(y - 54) = 0
y =2 or y = 54
Now, for y = 2 the value of x is 54 and for y = 54 the value of x is 2.
Hence, the two numbers are 2 and 54.

A population of geese doubles every 18 months. If there are 5 geese initially, how many years will it take for there to be 111 geese?
Answer: 7 years
Step-by-step explanation:
Let t be the number of periods in which geese doubles .
The exponential growth function:[tex]y=Ab^t[/tex] , where A = initial value , b= growth factor.
As per given , A = 5 , b=2
i.e. Number of geese after t periods = [tex]y=5(2)^t[/tex]
Put y=111, we get
[tex]111=5(2)^t\\\\\Rightarrow\ \dfrac{111}{5}=2^t\\\\\Rightarrow\ 22.2=2^t[/tex]
Taking log on both sides , we get
[tex]\log 22.2 = t\log 2\\\\\Rightarrow\ 1.346353=t(0.30103)\\\\\Rightarrow\ t=\dfrac{1.346353}{0.30102}\\\\\Rightarrow\ t=4.47263636\approx4.47[/tex]
Now , total months = 4.47 x 18 =80.46≈ 80 months
since 1 year =12 months
Number of years it will take [tex]=\dfrac{80}{12}=\dfrac{20}{3}=6.66666666667\approx7[/tex]
Hence, it will take 7 years (approx.)

It rains on Paradise Island on 40% of the days. The chance of rain is independent from day to day. A travel agent is signing people up to go on a 5-day tour of the island. She wants to know the chance of getting at least two consecutive days of rain at any time during the 5 days. To determine this, a simulation will be used.
Answer:
The probability that it will rain in atleast two consecutive days will be 0.167936.
Step-by-step explanation:
Since it rains on 40% of the days, then the probability of it raining on each day is
This follows a binomial distribution
Since it's a five-day tour and they want to know the probability that rain falls in atleast TWO CONSECUTIVE days then we have to consider 2 days as one, as we do in combination problems, so that they are always together before we use in our binomial probability density function.
Our Probability Density Function is given as
[tex]P(X) = \binom{n}{x} p^x \times q^{n-x}[/tex]
Where p is probability of raining and q = 1 - p is probability of not raining.
Our n is 4 since we are considering two days as one.
We are looking the P(X≥2) = 1 – P(X<2) = 1 – [P(X = 0) + P(X = 1).
[tex]P(X = 0) = \binom{4}{0} 0.4^0 \times 0.6^4 = 0.1296[/tex]
[tex]P(X = 1) = \binom{4}{1} 0.4^1 \times 0.6^3 = 4\times 0.4 \times 0.216 = 0.3456[/tex]
Therefore P(X≥2) = 1 – (0.1296 + 0.3456) = 0.5248.
Remember we combined two consecutive days that it will rain as one, their probabilities will be:
2! x 0.4 x 0.4 = 0.32
Therefore, the probability that it will rain in atleast two consecutive days will be
0.32 x 0.5248 = 0.167936
