Jude researched the prices of several different models of cell phones and made a scatter plot of his data. The equation of the line of best fit for Jude’s data is p = -2.76t + 99.05 , where p is the price of the phone and t is the number of months that the phone has been available. What is the real-world meaning of the slope of this line?
a:A phone’s price increases by about $2.76 each month that it is available.
b:The original price of each phone was $2.76.
c:A phone’s price decreases by about $2.76 each month that it is available.
d:The original price of each phone was $99.05.
Answer:$4.76 each month
Step-by-step explanation:

P(A and D) = [?]
===============================================
Explanation:
Highlight the path that starts with A and then leads to D
Multiply the values highlighted to get 0.5*0.6 = 0.3
Effectively we've computed the following
P(A and D) = P(A)*P(D given A)
P(A and D) = 0.5*0.6
P(A and D) = 0.3
The notation "D given A" indicates we know event A has happened. We cannot simply say P(D) because there is another event D that happens on the lower branch B; so instead we say P(D given A). You can replace the word "given" with a vertical bar to write P(D | A), though in my opinion the vertical bar could be easily mistaken for the uppercase letter i, a lowercase letter L, or the numeric digit "one". I find its easier to describe what is going on rather than use the vertical bar notation.

The population density of the world is calculated by finding the ratio of the total number of people in the world to the area of land. Since the earth is about 1.5 x 108 square kilometers, approximately how many people would inhabit each square kilometer of the earth? Show the work and / or explain your reason
Answer:
51
Step-by-step explanation:
A = Surface area of the Earth = [tex]1.5\times 10^8\ \text{km}^2[/tex]
Total number of people on Earth = 7.594 billion as of 2018 = [tex]7.594\times 10^9[/tex]
We need to find the number of people living in each square km of land area.
So, we need to divide the number of people by the land area of the Earth.
[tex]1.5\times 10^8\ \text{km}^2=7.594\times 10^9\ \text{people}[/tex]
[tex]\Rightarrow 1\ \text{km}^2=\dfrac{7.594\times 10^9}{1.5\times 10^8}[/tex]
[tex]\Rightarrow 1\ \text{km}^2=50.63\approx 51\ \text{people}[/tex]
So, 51 people will inhabit each square km of land area.

Calculate the quotient below and give your answer in scientific notation.
2.64*10^-3\8.0*10^0
Answer:
The quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex] is: [tex]\mathbf{3.3\times 10^{-4}}[/tex]
Step-by-step explanation:
We need to find quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex]
We know that [tex]10^0=1[/tex]
Now solving:
[tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033[/tex]
Writing it in scientific notation
[tex]0.00033\\=3.3\times10^{-4}[/tex]
So, the quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex] is: [tex]\mathbf{3.3\times 10^{-4}}[/tex]

Expand and combine like terms. (3-8w^2)^2
Answer:
64w^4 - 48w^2 + 9
Step-by-step explanation:
(I rearranged the terms so I could solve it easier)
Expanding the square:
(-8w^2 + 3)^2
(-8w^2 + 3)(-8w^2 + 3)
Combining like terms:
64w^4 - 24w^2 - 24w^2 + 9
64w^4 - 48w^2 + 9
Final answer: 64w^4 - 48w^2 + 9
Brianna bought a sandwich, apple, and cookie for lunch. The total was $5. if a sandwich costs six times more than the cookie, and an apple costs three times more than the cookie, how much does each item cost?
Answer:
Cookie=0.5, Apple=1.5, sandwich= 3
Step-by-step explanation:
Lets say cookie = x, then sandwich = 6x since sandwich is 6 times more expensive, apple = 3x. function: 6x+3x+x =5
10x=5
x=0.5
Answer:
The cookie costs $0.50, the apple costs $1.50, and the sandwich costs $3.
Step-by-step explanation:
I multiplied 0.50 by 3 (for the apple) and got 1.50, then I multiplied 0.50 by 6 (for the sandwich) and got 3. I then added them all together and got 5.
Q2. At a pizzeria, a plain slice of pizza costs $1.75, and each additional
topping costs $0.75. Jared buys a slice of pizza for a total cost of $4.00.
Which equation could be used to determine how many additional toppings
Jared had on his pizza? Let x = the number of toppings.
1.75x + 0.75 = 4
1.75 -0.75x = 4
1.75x -0.75 = 4
1.75 +0.75x = 4
Answer:
1.75+0.75x=4
Step-by-step explanation:
$1.75 is the set price, and you add $0.75 for every topping.

A clothing store is advertising t-shirts on sale for (x-3) dollars and skirts for (x + 6) dollars. Write an expression that represents the cost of 5 t-shirts and 3 skirts.
Answer:
8x + 3
Step-by-step explanation:
The cost of 5 t-shirts and 3 skirts
= 5(x - 3) + 3(x + 6)
= 5x - 15 + 3x + 18
= (5x + 3x) + (-15 + 18)
= 8x + 3
Answer:
5(x-3)+ 3(x+6)
Step-by-step explanation:
5 (x-3)+ 3(x+6)
A warehouse store sells 4.5-ounce cans of tuna in packages of 3. A package of 3 cans costs $4.32. The store also sells 3.5-ounce cans of the same tuna in packages of 4. A package of 4 cans costs $3.92. The store sells 6.5-ounce cans in packages of 5 cans for $9.75. Which package is the best buy?
Answer:
The 6.5-ounce cans offer the largest size at a fair cost and is the best to buy.
Step-by-step explanation:
Size of the 4.5-ounce cans of tuna in package = 4.5 × 3 = 13.5 ounce
Cost of the package= $4.32
Size of the 3.5-ounce cans = 3.5 × 4 = 14 ounce
Cost of the package= $3.92
Size of the 6.5-ounce cans = 6.5 × 5 = 32.5 ounce
Cost of the package= $9.75
The 6.5-ounce cans offer the largest size and is the best to buy.

Answer:
(0, -2) and (1, 1) both work in this system of equations.
Step-by-step explanation:
Happy to help! The best way to find if it is a solution is to look for those points on the graph. When we graph the point, it needs to fall in an area where both lines or shaded or on a solid line.
Look carefully and see if you can find points like these!
(0, -2) falls on a solid line.
(1, 1) falls in the double shaded area.
Therefore, (0, -2) and (1, 1) both work in this system of equations.
