According to records from the last 50 years, there is a 2/3 chance of June temperatures being above 80 F. Azul needs to find the probability that it will be above 80' F for 20 or more days this June. There are 30 days in June.
If we use a number cube with the values 1-6 and assign 1-4 as a temperature above 80' F and 5-6 as a temperature of 80' F or below, what is the BEST way to perform the simulation
Answers
The probability that temperature goes above 80 F =P= Success = 2/3.
The probability that the temperature goes below 80 F or 80 F =Q= Not Success= 1-2/3
=1/3
What is the probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
Number of Days in June = 30 Days
Probability, that it will be above 80 F for 20 or more days this June
[tex]=C\left(30,20\right)P^{20}Q^{10}+C\left(30,21\right)P^{21}Q^9+C\left(30,22\right)P^{22}Q^8....+C\left(30,30\right)P^{30}Q^0.[/tex]
The best way to perform stimulation if we use a number cube with the numbers 1-6 and assign 1-4 as a temperature above 80 F and 5-6 as a temperature 80 F or below, Shows that we have marked four numbers i.e (1-4) as the temperature above 80 F, so the maximum number of days in June are of temperature above 80 F and less number of days are of the temperature, which is below 80 F or equal to 80 F.By converting it into a cube then playing the game in the classroom by collecting money from classmates by making five groups and rolling cube five times, if the number from (1-4) comes after rolling the cube you will win $5 money and if the number from (5-6) comes you win $10.The group that has the maximum correct answers wins the game.
The probability that temperature goes above 80 F =P= Success =2/3.

Jenna wants to wrap a shipping box shaped like a rectangular prism. The box is 20 inches tall and has a square base with sides that each measure 3 inches. How much paper will she use?
Answers
Answer:
23 inches
Step-by-step explanation:
Explanation:
For this question, we are trying to find the surface area of the rectangular prism, not the area inside the rectangular prism because we are wrapping the box up.
So, If we break up the rectangular prism, we will get 4 rectangles that are 20 inches by 3 inches, and 2 squares (the base and the top) that are 3 inches by 3 inches.
What we have to do know is find the area of all these pieces, then add them together.
So for the 4 rectangles:
A = l x w
= 20 inches x 3 inches
= 60 inches
Since there’s 4 rectangles we do:
60 x 4 = 240 inches
For the 2 Squares:
A = l x w
= 3 inches x 3 inches
= 9 inches
since there’s 2 squares we do:
9 x 2 = 18 inches
Then we can add these totals up for the total surface area:
240 + 18 = 258 inches squared

Antibody - a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
Apoptosis - the death of cells which occurs as a normal and controlled part of an organism's growth or development.
Autoimmune disease - Autoimmune disease happens when the body's natural defense system can't tell the difference between your own cells and foreign cells, causing the body to mistakenly attack normal cells. There are more than 80 types of autoimmune diseases that affect a wide range of body parts.
B-cell - B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system.
T-cells - T cell, also called T lymphocyte, type of leukocyte (white blood cell) that is an essential part of the immune system. T cells are one of two primary types of lymphocytes—B cells being the second type—that determine the specificity of immune response to antigens (foreign substances) in the body.
Helper - A type of immune cell that stimulates killer T cells, macrophages, and B cells to make immune responses. A helper T cell is a type of white blood cell and a type of lymphocyte. Also called CD4-positive T lymphocyte.
Killer - A type of immune cell that has granules (small particles) with enzymes that can kill tumor cells or cells infected with a virus. A natural killer cell is a type of white blood cell. Also called NK cell and NK-LGL.
Supresor - A tumor suppressor gene (TSG), or anti-oncogene, is a gene that regulates a cell during cell division and replication. If the cell grows uncontrollably, it will result in cancer. When a tumor suppressor gene is mutated, it results in a loss or reduction in its function.
Memory - Memory is the ability of the brain to encode, store and retrieve information when required.
Leukocyte - A white blood cell, also known as a leukocyte or white corpuscle, is a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and disease.
Erythrocyte - A blood cell with hemoglobin-rich cytoplasm and whose main function is to transport respiratory gases, chiefly oxygen
Lymphocyte - a form of small leucocyte (white blood cell) with a single round nucleus, occurring especially in the lymphatic system.
Lymph nodes - Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen (belly), and groin. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. There are hundreds of lymph nodes throughout the body.
Macrophage - a large phagocytic cell found in stationary form in the tissues or as a mobile white blood cell, especially at sites of infection.
Mast cells - Mast cells are blood cells that are part of your immune system. They help you fight infections, but they are also involved in allergic reactions. Mast cells live longer than normal cells, and they grow in your bone marrow, your gastrointestinal tract, your skin, and your airways.
Pathogen - A pathogen is defined as an organism causing disease to its host, with the severity of the disease symptoms referred to as virulence. Pathogens are taxonomically widely diverse and comprise viruses and bacteria as well as unicellular and multicellular eukaryotes.
Phagocyte - A pathogen is defined as an organism causing disease to its host, with the severity of the disease symptoms referred to as virulence. Pathogens are taxonomically widely diverse and comprise viruses and bacteria as well as unicellular and multicellular eukaryotes.

Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 0.4 In other words, a change of 1 unit in x corresponds to a change of 0.4 units in y. Graph the line and write the equation of the line.
PLS HELP WILL GIVE BRANLIEST + 20 POINTS
Answers
So here the 'unit rate of change' means the slope. It's also referred to as 'rise over run'. A line can be expressed in the form y=mx+b, where m is the slope and b is the y intercept. So here, m is equal to 0.4 and the line is y=0.4x
Think of it this way: if you plug in 1 for x, you get 0.4 for y. So that matches what the problem was saying about a change of 1 unit in x means 0.4 units in y. To graph it, start at 0,0 and move 0.4 up in y direction (rise) and 1 to the right in the x direction (run). If you keep doing that and connect the points, that will be the line
Explain the answer
When x= 5 y=0.4 x 5=2 (5,-2) Tip equation of line is y=lax straight line must pass point (0,0)

To FindDifference between the population of the two cities
Solution[tex] \text{{Assuming the population of two cities as}} \: \text{c}_1 \text{ and} \: \text{c}_2[/tex]
[tex] \text{ In Case of }\text{c}_1[/tex]
[tex]\text{c}_1 = -150\text{t} + 50,000 \\ \implies \text{c}_1 = - 150 \times 4 + 50,000 \\ \implies \text{c}_1 = - 600 + 50,000 \\ \implies \text{c}_1 = 49,400[/tex]
[tex] \text{ In Case of }\text{c}_2[/tex]
[tex]\text{c}_2 = 50\text{t} + 75,000 \\ \implies \text{c}_2 = 50\times 4 + 75,000 \\\implies \text{c}_2 = 200+ 75,000 \\ \implies \text{c}_2 = 75,200[/tex]
Now, We need to find the difference in their population
[tex]\text{c}_2 - \text{c}_1 \\ = 75,200 - 49,400 \\ = 25,800[/tex]

Answers
Answer:
146 m²
Step-by-step explanation:
The total base area = base x length = 4 x 11 = 44 (1)
The area of each triangular surface = /2 x base x height = 1/2 * 4 * 3.5 = 7 and the areas of both triangular surfaces = 2 x 7 = 14 (2)
The surface area of each of the lateral surfaces = side of triangle x length = 4 x 11 = 44
The area of both lateral surfaces = 2 x 44 = 88 (3)
Adding up (1), (2) and (3) gives us 146 m² as the total surface area
