Answer:
The probability of tossing a fair coin and it landing on heads 8 times in a row is (1/2)^8 = 1/256. This means that there is a 1 in 256 chance that a fair coin will land on heads 8 times in a row. The probability of an event can be calculated by taking the number of favorable outcomes and dividing it by the number of possible outcomes. In this case, there is only one favorable outcome (tossing a heads 8 times in a row) and two possible outcomes for each toss (heads or tails), so the probability is 1/2^8 = 1/256.

a) ( ∘ )(4)
b) (∘)(4)
c) (h∘∘)(−5)
d) ( ∘ )()
e) (∘)
f) (h∘)
a) (f ∘ g)(4) = 2
b) (g ∘ f)(4) = √2 + 5
c) (h ∘ g ∘ g)(-5) = 2 - 1/ (√(2√5) + 5)
d) (g ∘ f)(x) = √(x + 5) + 5.
e) (f ∘ g)(x) = √(√x + 5) + 5
f) (h ∘ f)(x) = 2 - 1/ (√x + 5)
What is Function?
A function is an expression or relationship that involves one or more variables. It has several inputs and outputs.
a) (f ∘ g)(4) means plugging in the value of 4 into g(x) and then plugging the result into f(x). So we have:
g(4) = √4 + 5 = √9 = 3
f(g(4)) = f(3) = √3 + 5 = 2
Therefore, (f ∘ g)(4) = 2.
b) b) (g ∘ f)(4) means plugging in the value of 4 into f(x) and then plugging the result into g(x). So we have:
f(4) = √4 = 2
g(f(4)) = g(2) = √2 + 5
Therefore, (g ∘ f)(4) = √2 + 5.
c) (h ∘ g ∘ g)(-5) means plugging in the value of -5 into g(x) twice, and then plugging the result into h(x). So we have:
g(-5) = √(-5) + 5 = √(20) = 2√5
g(g(-5)) = g(2√5) = √(2√5) + 5
h(g(g(-5))) = h(√(2√5) + 5) = 2 - 1/ (√(2√5) + 5)
Therefore, (h ∘ g ∘ g)(-5) = 2 - 1/ (√(2√5) + 5).
d) (g ∘ f)(x) means plugging in the function f(x) into g(x), which gives:
g(f(x)) = √(x + 5) + 5
Therefore, (g ∘ f)(x) = √(x + 5) + 5.
e) (f ∘ g)(x) means plugging in the function g(x) into f(x), which gives:
f(g(x)) = √(√x + 5) + 5
Therefore, (f ∘ g)(x) = √(√x + 5) + 5.
f) (h ∘ f)(x) means plugging in the function f(x) into h(x), which gives:
h(f(x)) = 2 - 1/ (√x + 5)
Therefore, (h ∘ f)(x) = 2 - 1/ (√x + 5).

. three coins are tossed up in the air, one at a time. what is the probability that two of them will land heads up and one will land tails up?
The probability of receiving two heads and one tail is 3/8, or 0.375.
One of the areas of probability theory is the estimation of the chance of experiments occurring. Using a probability, we can calculate everything from the likelihood of getting heads or tails when flipping a coin to the likelihood of making a research error, for example. It is essential to appreciate the most basic definitions of this branch, such as the formula for computing probabilities in equiprobable sample spaces, the likelihood of two events joining together, the probability of the complementary event, etc., in order to properly understand it .Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. Mathematics has incorporated probability to forecast the likelihood of various events.

Solve the value for k:
[tex]\displaystyle{\lim_{x\to \infty} \left(1+\dfrac{65}{x}\right)^{3x} = e^k}[/tex]
The value of k in the exponential function is -3.
What is the value of k in the exponential function?
Taking the natural logarithm of both sides of the equation, we have:
ln [ (1 + 65/x)^(3x) ] = ln(e^k)
Using the properties of logarithms, we can simplify the left side of the equation:
3x ln(1 + 65/x) = k
Taking the limit as x approaches infinity, we have:
lim (x → ∞) 3x ln(1 + 65/x)
= lim (x → ∞) [ln(1 + 65/x) / (1/x)] × 3
Using L'Hopital's rule, we can evaluate the limit:
lim (x → ∞) [ln(1 + 65/x) / (1/x)]
= lim (x → ∞) [-65 / (x(1+65/x))]
= -65/65
= -1
Therefore, we have:
lim (x → ∞) 3x ln(1 + 65/x)
= lim (x → ∞) [ln(1 + 65/x) / (1/x)] × 3
= -3

If one bottle holds 750 mL of lemonade how much lemonade will 24 bottles hold tell me two answers
The total volume of lemonade held by 24 bottles would be 18,000 mL (750 mL x 24) or 24x 0.75 liters = 18 liters.
And it would be to express the total volume in terms of the volume of one bottle. You can say that 24 bottles of lemonade is equal to 18 times the volume of one bottle, or 18 x 750 mL = 18,000 mL. This can also be written as 24 x 0.75 liters = 18 liters. This can also be expressed as 18 liters, since 1 liter is equal to 1000 mL.
Regardless of how you choose to express the answer, both methods give us the same result: 24 bottles of lemonade hold a total of 18,000 mL or 18 liters of the beverage. This information can be useful in various contexts, such as for planning a party or for ordering supplies for a lemonade stand. It's important to note that while both answers give the same result, they present the information in different ways. The first answer provides the total volume of lemonade held by all 24 bottles, while the second answer provides the number of times the volume of one bottle is contained within the total volume.

A jar contains 70 L of juice. It is poured into
glasses, each of 150 mL capacity. How many glasses
are completely filled with the juice and how much juice
is left in the jug?
First, we need to convert the volume of the juice in the jar from liters to milliliters, since the volume of the glasses is given in milliliters.
1 liter = 1000 milliliters
So, 70 liters = 70 * 1000 = 70,000 milliliters
Next, we'll divide the volume of the juice in the jar by the volume of each glass to find out how many glasses can be filled with the juice.
70,000 milliliters ÷ 150 milliliters/glass = 466.67 glasses (rounded to the nearest whole number)
Therefore, 466 glasses can be filled completely with the juice.
Finally, we can find out how much juice is left in the jar by subtracting the total volume of the juice used to fill the glasses from the volume of the juice in the jar.
70,000 milliliters - (466 glasses x 150 milliliters/glass) = 70,000 milliliters - 69900 milliliters = 800 milliliters
So, 800 milliliters of juice is left in the jar.

The appropriate measure of variation (spread) for these data is the standard deviation. Standard deviation is a measure of how much the data values vary from the mean (average) of the data set. It is calculated by taking the square root of the variance, which is the average of the squared differences between each data value and the mean.
To calculate the standard deviation for this data set, follow these steps:
1. Find the mean of the data set by adding up all of the data values and dividing by the total number of values. In this case, the mean is (4 + 7 + 2 + 3 + 4 + 2 + 1 + 3 + 9 + 8 + 5 + 1 + 3 + 2 + 3 + 2 + 4 + 3 + 6 + 5) / 20 = 3.65
2. Find the variance by subtracting the mean from each data value, squaring the result, and then finding the average of these squared differences. The variance for this data set is ((4 - 3.65)^2 + (7 - 3.65)^2 + (2 - 3.65)^2 + ... + (6 - 3.65)^2 + (5 - 3.65)^2) / 20 = 5.2275
3. Take the square root of the variance to find the standard deviation. The standard deviation for this data set is sqrt(5.2275) = 2.287
Therefore, the appropriate measure of variation (spread) for these data is the standard deviation, which is 2.287.

Terrel has enough money to either
buy one large jar has which has a diameter of 8 cm, and a height of 16 cm.
or
buy three small jars of jam which have a diameter of 6 cm, a height of 7 cm.
Which option will give him the most jam to give to his grandmother? Please explain your answer and your reasoning in complete sentences. Be sure to explain each step that requires a computation. Use key vocabulary like "volume of a cylinder."
Answer:
A large container is a better deal because for a large container the amount of jam per dollar is greater thank that in the three smaller containers.
Step-by-step explanation:
What is the volume of a cylinder?
The volume of a cylinder is given by -
V[c] = πr²h
Given is Terrel who has to buy either one large jar or three small jars of jam. A small jar has a diameter of 6 cm, a height of 7 cm, and costs $4. A large jar has a diameter of 8 cm, a height of 16 cm, and costs $12.
For one large container, its volume will be -
V[L] = πr²h = 22/7 x 4 x 4 x 16 = 804.56 cm³
Amount of jam per dollar = V[1] = 804.56 / 12 = 67.04 cm³
For three small containers, the total volume will be -
V[S] = πr²h = {22/7 x 3 x 3 x 7} x 3 = 594 cm³
Amount of jam per dollar = V[2] = 594 / 12 = 49.5 cm³
It can be seen that for a large container the amount of jam per dollar is greater than that in the three small container. Hence, a big container would be a better deal for Terrell.
Therefore, a large container is a better deal because for a large container the amount of jam per dollar is greater than that in the three small container.

Peter has a total of 22 nickels and dimes. There is a total of $1.80. Which of the following is a possible combination of coins that Peter has?
====================================================
Work Shown:
n = number of nickels
22-n = number of dimes
5n = value of the nickels in cents
10(22-n) = value of the dimes in cents
5n+10(22-n) = total value in cents
5n+10(22-n) = 180
5n+220-10n = 180
-5n+220 = 180
-5n = 180-220
-5n = -40
n = -40/(-5)
n = 8 is the number of nickels
22-n = 22-8 = 14 is the number of dimes
-----------------
Check:
8 nickels = 8*5 = 40 cents
14 dimes = 14*10 = 140 cents
8 nickels + 14 dimes = 40 cents + 140 cents = 180 cents = $1.80

Total cost is a term used in economics to describe the least expensive way to produce a specific amount of a good (TC). Fixed costs, which are unaffected by the quantity of a good produced and include inputs like buildings and machinery, possibly including sunk costs, and variable costs, which change with the quantity of a good produced and include inputs like labor and raw materials, make up the total economic cost of production. Economics considers the total potential cost of each manufacturing item as one of the total cost's fixed or variable costs.

For given geometrical shape, The angles which we need to find are ∠z=115° and y=21.
What are geometric shapes, exactly?
Geometric shapes are mathematical figures that reflect the shape of objects we see in our daily lives. Shapes are geometric shapes that have boundary lines, angles, and surfaces. There are several types of 2d and 3d shapes.
Shapes are also classified according to their regularity or homogeneity. A symmetrical regular form, such as a square or circle, is common. Asymmetry can take on irregular shapes. They're also referred to as organic forms or freeform shapes. A tree, for example, has an irregular or organic shape.
In plane geometry, two-dimensional forms are flat shapes and closed figures such as circles, squares, rectangles, rhombuses, and so on. In solid geometry, the three-dimensional shapes are the cube, cuboid, and sphere.
Now,
In given figure ∠z+65°=180° (Sum of two interior angles)
