Neil's Ice Creamery sold 50 sundaes last week. There were nuts on 22 of the sundaes. What is the ratio of the number of sundaes with nuts to the number of sundaes without nuts?
The ratio of the number of sundaes with nuts to the number of sundaes without nuts is 11/14
What is ratio?
Ratio is a quantitative relationship between two values indicating the number of times one value contains within the other value
In other words, we are expressing the number of sundaes with nuts as a fraction of the ones without nuts
There are 22 sundaes with nuts
number of sundaes without nuts=50-22
number of sundaes without nuts=28
sundaes with nuts/sundaes without nuts=22/28

Answer:
Problem 1: y = 4x + 6
Problem 2: 48 soda bottles per minute
Step-by-step explanation:
Problem 1:
Equation of a line in slope-intercept form is given as y = mx + b.
Wee have to figure out the value of the slope (m) and the value of y-intercept (b). Them to write an equation that represents the line of the graph, we need to input the values of m and b into the equation, y = mx + b.
Thus,
m = hourly fee = $4
b = initial deposit = $6
Substitute m = 4 and b = 6 into y = mx + b
Equation would be:
y = 4x + 6
Problem 2:
What we are simply asked to do is to find the slope of the line, which is the number of soda bottles the machine will produce per minute
Using the two points (3, 144) and (8, 384),
Slope = ∆y/∆x = (384 - 144)/(8 - 3)
Slope = 240/5 = 48
Thus, the machine will make 48 bottles per minute

Problem of Tartaglia (1500-1577): among all positive numbers a, b whose sum is 8, find those for which the product of the two numbers and their difference is largest. (Enter your answers as a comma-separated list.)
a, b = _____
Let x = a - b and express abx in terms of x alone.
As per the information provided, a = 4√3/3 + 4, b = 4 - 4√3/3 the answer can be calculated with optimization method. it will be as follows:
Sum of a and b is 8, we get
a+b=8
b=8−a
Now, let x=a−b
Then we get,
\(x=a−(8−a) \\ x=2a−8 \\ x+8=2 \\ 1 \div 2x+4=a
\)
we use this to answer to solve for b
\(b=8−a \\ =8−(1 \div 2x+4) \\ =4−1 \div 2x
\)
Now we use the product of two numbers and its difference. This can be expressed as:
\(a⋅b⋅x=(1 \div 2x+4)(4−1 \div 2x) \\ x=2 {x}^{2} − \frac{1}{4} {x}^{3} +16x−2x^{2} \\ =−14x^{3} +16x
\)
Thus, this expression that we need to maximize. Take the derivative, set it equal to zero, and solve for x
\(−3 \div 4x ^{2} +16=0 \\ 16 =3 \div 4 x ^{2} \\ 643=x \\ 28√3 \div 3=x\)
Now for us to check that this is a maximum, we have to note that the second derivative is
\(−3 \div 2x
\\ At \\
x=8√3 \div 3
\)
the second derivative is −4√3. Since this number is negative, the point is a maximum.
Now we must find the values of a and b for this x. We have to use the relationship
\(a=1 \div 2x+4\)
\(a=1 \div 2 \times 8√3 \div 3+4 \\ =4√3 \div 3+4\)
now we use the relationship b=8−a
\(b=8−(4√3 \div 3+4) \\ =4−4√3 \div 3\)
The first step in determining a function's maximum or minimum value is differentiating it. Then, set this derivative to zero and conduct the computation.
x. This will reveal the location of a function's maximum or minimum, but it won't reveal which.

Suppose a household of 4 people produces 128 lb of garbage in one week. At this rate, how many pounds will 48 people produce in 1 week?
Answer:
1,536 lb or 696.718 kg
verification:
4 p = 128 lb
48 p = ?
48 ÷ 4 = 12
128 × 4 = 1,536 lb
48 p = 1,536 lb
explanation:
If 4 people make 128 lb of garbage in one week then 48 people would make 1,536 lb of garbage in one week because the difference between 4 and 48 is 12 (48 ÷ 4 = 12) so if you multiply 128 lb by 12 you get 1,536 lb of garbage ( 128 × 12 = 1,536 lb).
If your observed Z or t statistic falls in the "critical region," what can you conclude?
If your observed Z or t statistic falls in the "critical region," it means that the probability of obtaining a value as extreme or more extreme than the observed statistic is very low, assuming the null hypothesis is true.
The critical region is a range of values of a test statistic, such as Z or t, that indicate the rejection of the null hypothesis. In hypothesis testing, the null hypothesis is a statement that there is no significant difference between two groups or that there is no effect of an intervention. The alternative hypothesis is the opposite of the null hypothesis, and it suggests that there is a significant difference or an effect of the intervention.
The critical region is determined by the level of significance, which is a pre-specified threshold that is usually set at 0.05 or 0.01. If the observed test statistic falls within the critical region, it means that the probability of obtaining a value as extreme or more extreme than the observed statistic is very low, assuming the null hypothesis is true. This probability is called the p-value. Therefore, you would reject the null hypothesis and conclude that there is a significant difference or relationship between the variables being studied.

A bicycle collector has 100 bikes. How many ways can the bikes be stored in four warehouses if the bikes and the warehouses are considered distinct? What if the bikes are indistinguishable and the warehouses distinct?
There are 176,851 ways to store the bikes in four distinct warehouses if the bikes are indistinguishable and the warehouses are distinct.
How to find the way to store the bike?Let's consider the two scenarios separately:
Scenario 1: Bikes and warehouses are considered distinct.
In this case, each bike and each warehouse is considered distinct. We need to find the number of ways to distribute 100 distinct bikes among 4 distinct warehouses.
To solve this, we can use the concept of stars and bars. Imagine we have 100 stars representing the bikes, and we want to separate them into 4 distinct groups (warehouses) using 3 bars.
The number of ways to distribute the bikes can be calculated as (100 + 3) choose 3:
Number of ways = (100 + 3)C3 = 103C3 = (103 * 102 * 101) / (3 * 2 * 1) = 176,851.
Therefore, there are 176,851 ways to store the bikes in four distinct warehouses if the bikes and warehouses are considered distinct.
Scenario 2: Bikes are indistinguishable, warehouses are distinct.
In this case, the bikes are indistinguishable, but the warehouses are distinct. We need to find the number of ways to distribute 100 identical bikes among 4 distinct warehouses.
This problem can be solved using the concept of stars and bars again. Since the bikes are indistinguishable, the placement of bars doesn't matter.
We can think of it as distributing the 100 bikes into 4 distinct groups (warehouses) using 3 bars. The number of ways to do this can be calculated as (100 + 3) choose 3:
Number of ways = (100 + 3)C3 = 103C3 = (103 * 102 * 101) / (3 * 2 * 1) = 176,851.
Therefore, there are 176,851 ways to store the bikes in four distinct warehouses if the bikes are indistinguishable and the warehouses are distinct.

In 2020 Phoenix, AZ was the fastest growing cities in the United States. In 2020 the population was approximately 1,730,000. The city population grew by 25,000 people that year. Write a model for the population of Phoenix x years after 2020 assuming it continues to grow by 25,000 people per year.
Answer : P(x) = 25,000x + 1,730,000P(x) represents the population of Phoenix after x years since 2020.
Explanation:
Given information: The population of Phoenix in 2020 was approximately 1,730,000 and the city's population grew by 25,000 people in 2020.
Model for the population of Phoenix x years after 2020 if it continues to grow by 25,000 people per year:
To find the population of Phoenix after x years since 2020, we need to add the number of people that moved into Phoenix since 2020, i.e., 25,000 people per year.
If x represents the number of years since 2020, then the model is given as follows:
P(x) = 25,000x + 1,730,000P(x) represents the population of Phoenix after x years since 2020.
We need to add 1,730,000 to 25,000x because 1,730,000 is the initial population in 2020.
Therefore the required model P(x) = 25,000x + 1,730,000P(x) represents the population of Phoenix after x years since 2020.

Telephone calls to the national reservation center for motels were studied. A certain model defined a Type I call to be a call from a motel's computer terminal to the national reservation center. For a certain motel, the number, X, of Type 1 calls per hour has a Poisson distribution with parameter 1 = 1.5. Answer the following questions. a. Determine the probability that the number of Type 1 calls made from this motel during a period of 1 hour will be exactly two. The probability that exactly two Type 1 calls are made is (Do not round until the final answer. Then round to four decimal places as needed.) b. Determine the probability that the number of Type 1 calls made from this motel during a period of 1 hour will be at most two. The probability that at most two Type 1 calls are made is (Do not round until the final answer. Then round to four decimal places as needed.) c. Determine the probability that the number of Type 1 calls made from this motel during a period of 1 hour will be at least four. (Hint: Use the complementation rule.) The probability that at least four Type 1 calls are made is (Do not round until the final answer. Then round to four decimal places as needed.) d. Find the mean of the random variable X. HE e. Find the standard deviation of the random variable X.
a. The probability that exactly two Type 1 calls are made from the motel during a period of 1 hour is 0.3347. b. The probability that at most two Type 1 calls is 0.6767. c. The probability that at least four Type 1 calls is 0.1072. d. The mean of the random variable X is 1.5. e. The standard deviation of the random variable X is approximately 1.2247.
a. The probability of exactly two Type 1 calls can be calculated using the Poisson distribution formula with a parameter of λ = 1.5. Plugging in the value of k = 2, we get a probability of 0.3347.
b. The probability of at most two Type 1 calls can be calculated by summing the probabilities of 0, 1, and 2 Type 1 calls. Using the Poisson distribution formula, we can calculate the probabilities for each value and sum them up. This gives us a probability of 0.6767.
c. The probability of at least four Type 1 calls can be calculated using the complementation rule. The complement of "at least four calls" is "less than four calls." We calculate the probabilities of 0, 1, 2, and 3 Type 1 calls, and subtract this sum from 1. This gives us a probability of 0.1072.
d. The mean of a Poisson distribution is equal to its parameter λ, which in this case is 1.5.
e. The standard deviation of a Poisson distribution is equal to the square root of its parameter λ. Taking the square root of 1.5, we get approximately 1.2247.
