Answer:

26.4

Step-by-step explanation:

You can add Y together because they have the same variable making it 10y

The equation is now 10y - 84 = 180

Add 84 to 180 since on the left side it was -84 (Imagine it crossed a magic bridge and become the opposite of what it is)

The equation is now 10y = 264

Divide the equation by 10 because 10 crossed a "magic bridge" to the other side and became division instead of multiplication

The equation is now solved = 26.4

We can cross check this by adding it to the first equation

3(26.4) + 7(26.4) - 84

which gives us 180

Hope this helps

Answer: y=26.4

Step-by-step explanation:

First we need to simplify 3y+7y .... that would be 10y.

Now we have 10y-84=180. We can add 84 to both sides of the equation

So now we have 10y= 180+84 = 10y= 264

Divide both sides by 10= y= 26.4

Now we can check this answer by inputting 26.4 to all the y values in the equation.

(3*26.4) +(7*26.4) - 84=180

79.2 + 184.8 -84=180

180=180    so we know 26.4 is the correct answer

The the speed of a car that travels the given distance in 5 seconds from the information is 65.6 mph.

Speed and time are two fundamental concepts in physics and mathematics that are often used together to describe the motion of objects.

Speed refers to how fast an object is moving, and is typically measured in units of distance per unit of time, such as meters per second (m/s) or miles per hour (mph). Speed can be either constant, meaning the object is moving at the same speed throughout its motion, or variable, meaning the object's speed changes over time.

Given that the speed R varies inversely with the time T

R = 41 mph T =  8 seconds

The distance can be calculated as( speed * time)

Distance = ( speed * time)

= 41 * 8 = 328miles

The total distance travel  can now bw seen as 328miles, the speed  of a car that travels the given distance in 5 seconds can now be calculated as

Speed =Distance / time.

= 328miles/ 5 seconds

= 65.6 mph.

If f ( x ) = f ( g ( x ) ) , where f ( 5 ) = 7 , f ' ( 5 ) = 5 , f ' ( 0 ) = 3 , g ( 0 ) = 5 , and g ' ( 0 ) = 3 ,f'(0) = 15

We start by using the chain rule to find the derivative of f(x) with respect to x:

f'(x) = f'(g(x)) * g'(x)

Next, we evaluate this equation at x = 0, and use the given values to solve for f'(0):

f'(0) = f'(g(0)) * g'(0)

f'(0) = f'(5) * 3 (since g(0) = 5 and g'(0) = 3)

Now, we need to find f'(5) using the given information. We can start by using the definition of the derivative:

f'(5) = lim h->0 [f(5+h) - f(5)] / h

We know that f(5) = 7, so we can simplify this expression:

f'(5) = lim h->0 [f(5+h) - 7] / h

Using the fact that f(x) = f(g(x)), we can substitute g(x) for x:

f'(5) = lim h->0 [f(g(5+h)) - 7] / h

Now, we can use the mean value theorem to approximate f(g(5+h)):

f'(5) = lim h->0 [f'(g(c)) * g'(5+h)] / 1

where 5 < c < 5 + h. Since f'(5) = 5 and g'(5) = 3, we can simplify this expression:

f'(5) = lim h->0 [5 * 3] / 1 = 15

Therefore, we have found that f'(0) = f'(5) * 3 = 5 * 3 = 15.

Therefore, there were 5 friends with Dylan at the cafe.

Let's start by subtracting the change Dylan received from the amount he paid to find out the total cost of everything he bought:

Total cost =

We know that Dylan bought himself a cup of tea, which costs less than a cup of coffee. So, the £5.39 must have been spent on buying coffee for his friends.

Let's assume that each cup of coffee costs £1. We can use this assumption to find out how many cups of coffee Dylan bought for his friends:

Number of cups of coffee = total cost ÷ cost per cup of coffee = £5.39 ÷ £1 = 5.39

Since we can't buy a fraction of a cup of coffee, we can round this number down to the nearest whole number. Therefore, Dylan bought 5 cups of coffee for his friends.

However, we need to remember that Dylan himself also bought a drink, which wasn't a cup of coffee. So, the total number of people at the cafe was:

A function that converts an input of letters and numbers into an encrypted output of a fixed length is called hash. The links in the blockchain that is created using an algorithm.

A hash is a mathematical function that changes an input of any length into an encrypted output of a specific length. Therefore regardless of the quantity of raw data involved or the size of the file, its unique hash is always the same size. Also, a hash cannot be used to "reverse engineer" an input from a hash output, because hash functions are "one-way" (like a meat grinder; you don't can't put ground beef back into a steak). However, if you use such a function on the same data, its hash will be the same, so you can confirm that the data is the same (i.e., unchanged) if you already know its hash.

Hashes are used in various parts of the blockchain system. Each block header contains the hash of the previous block, ensuring nothing has been tampered with as new blocks are added. Cryptocurrency blockchains use hashes to secure information and make the ledger immutable.

It refers to the technique of making an input element of arbitrary length reflect an output element of definite length. For blockchain applications in cryptocurrencies, variable duration transactions are processed by specific hashing algorithms and all produce fixed length outputs. This is true regardless of the duration of the input transaction.

We don't have enough information to determine the exact side length of either square A or square C, so we cannot directly calculate their areas. However, we can use the relationship between the areas of the squares to make some conclusions.

Since the area of square B is 64 square units, we know that its side length is √64 = 8 units.

Similarly, since the area of square C is 100 square units, we know that its side length is √100 = 10 units.

Square A is composed of square B and four identical triangles. We know the area of square B is 64 square units, so we need to determine the area of the four triangles to find the area of square A.

Each triangle has a base of 8 units (which is also the length of one side of square B) and a height of half the length of one side of square A. Let's call this length x.

The area of one triangle is (1/2) * 8 * x = 4x square units.

The total area of the four triangles is 4 times the area of one triangle, which is 16x square units.

Therefore, the area of square A is 64 + 16x square units.

We still don't know the exact value of x, but we can make some observations. Since square A is larger than square B, we know that x > 4. And since the triangles make up exactly half of square A (the other half being square B), we know that the area of square A is twice the area of the four triangles. Therefore:

64 + 16x = 2(16x)

64 + 16x = 32x

64 = 16x

x = 4

So the length of each side of square A is 8 + 2x = 16 units, and its area is 64 + 16x = 128 square units.

The length of CA is just the length of one side of square C, which is 10 units.

This is the simplified ratio of lengths DE:EF as (2/√(29))√(34) : 1.

A ratio is a relationship between two or more quantities that indicates how many times one quantity is contained in another. It is a way of comparing quantities of the same kind, such as lengths, areas, volumes, or numbers. A ratio is usually expressed as a fraction or a colon (:). Ratios can be simplified by dividing both terms of the ratio by their greatest common factor (GCF). Ratios are used in many fields such as mathematics, finance, science, engineering, and statistics, among others. They are used to compare different quantities, to express proportions or rates, and to solve various mathematical problems.

Here,

We can use the distance formula to find the lengths DE and EF, and then calculate their ratio:

Length DE = √[(xE - xD)² + (yE - yD)²]

= √[(10 - 4)² + (15 - 4)²]

= √(6² + 11²)

= √(136)

= 2√(34)

Length EF = √[(xF - xE)² + (yF - yE)²]

= √[(12 - 10)² + (20 - 15)²]

= √(2² + 5²)

= √(29)

Therefore, the ratio of lengths DE:EF is:

DE:EF = (2√(34)) : (√(29))

We can simplify this ratio by dividing both sides by √(29):

DE:EF = (2√(34))/√(29) : (√(29))/√(29)

= (2/√(29))√(34) : 1

The confidence interval (461.7, 598.1) estimates the true population parameter of the expected lead content when traffic flow is 15. In this case, the parameter being estimated is the population mean of lead content at a specific level of traffic flow, which is denoted by the symbol μ.

Option (c) "μ lead content, the average lead content" is the correct option, as the confidence interval provides an estimate of the true population mean of lead content when the traffic flow is at a specific level (in this case, 15).

Option (a) "β, the average change in lead content with a change in traffic flow" is not applicable here since the confidence interval is estimating the mean lead content at a specific level of traffic flow, not the change in lead content with a change in traffic flow.

Option (b) "μ lead content traffic flow = 15, the average lead content when traffic flow is 15" is partially correct, but it is important to note that this is a conditional mean, which is the mean of lead content given that the traffic flow is 15.

The 99% confidence interval for the population proportion is (0.257, 0.583).

(a) The point estimate of the population proportion of plants alive after the first month in the more humid environment is:

point estimate = x/n = 21/50 = 0.42

So, the point estimate is 0.42.

(b) To find the 95% confidence interval for the population proportion, we can use the formula:

confidence interval = point estimate ± z√(point estimate(1-point estimate)/n)

where z is the z-score corresponding to the desired confidence level, n is the sample size, and √ represents the square root.

For a 95% confidence level, z = 1.96 (from a standard normal distribution table).

Plugging in the values, we get:

confidence interval = 0.42 ± 1.96√(0.42(1-0.42)/50)

= 0.42 ± 0.127

= (0.293, 0.547)

So, the 95% confidence interval for the population proportion is (0.293, 0.547).

(c) To find the 99% confidence interval for the population proportion, we can use the same formula but with a different z-score.

For a 99% confidence level, z = 2.58 (from a standard normal distribution table).

Plugging in the values, we get:

confidence interval = 0.42 ± 2.58√(0.42(1-0.42)/50)

= 0.42 ± 0.163

= (0.257, 0.583)

The 99% confidence interval for the true average number of alcoholic drinks all UF female students have in a one week period is option (d)  (3.35, 4.75)

To construct a confidence interval for the true average number of alcoholic drinks all UF female students have in a one week period, we can use the following formula

Confidence interval = sample mean ± (critical value) x (standard error)

Where the standard error is calculated as

Standard error = standard deviation / square root of sample size

We are given

Sample size (n) = 170

Sample mean (X) = 4.05

Standard deviation (s) = 4.66

Confidence level = 99%

To find the critical value, we need to look up the t-value with 169 degrees of freedom (since we are using a t-distribution because the sample size is less than 30) and a 99% confidence level. Using a t-distribution table or a calculator, we find the t-value to be approximately 2.62.

Substituting the values into the formula, we get:

Standard error = 4.66 / √170 ≈ 0.357

Confidence interval = 4.05 ± (2.62) x (0.357) ≈ (3.35, 4.75)

What is cylinder ?

A cylinder is a multi object used in geometry that has a round base, a curving surface rising from it, and another circular shape at the top or lid. One way to visualize a cylinder is as a stack of infinitely thin circular discs stacked one on top of the other. The height and radius of a cylinder, which measure the distance from the base to the top and the edge of the circular base, respectively, determine the shape of the object.

The plastic wrap covers the entire surface area of the cylinder. The formula for the surface area of a cylinder is:

Surface area of cylinder = 2πr² + 2πrh

where r is the radius of the circular base of the cylinder, and h is the height of the cylinder.

We can use the given diameter of the circular base, which is 1.8 inches, to find the radius r:

r = d/2 = 1.8/2 = 0.9 inches

We are also given the height of the rectangle, which is 0.8 inches.

Now we can substitute the values of r and h into the formula for the surface area of the cylinder:

Surface area of cylinder = 2π(0.9)² + 2π(0.9)(0.8)

Surface area of cylinder = 2π(0.81) + 2π(0.72)

Surface area of cylinder = 1.62π + 1.44π

Surface area of cylinder = 3.06π square inches

Step-by-step explanation:

The standard deviation of demand over the lead time is 23.72.

The demand over lead time is normally distributed with a mean of 80. The reorder point for a 95% service level is 119. To calculate the standard deviation of demand over the lead time, we need to use the following formula:

z = (x - μ) / σ, where z is the number of standard deviations from the mean, x is the reorder point for a 95% service level, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

To solve for σ, we need to first find the z-score for a 95% service level, which can be obtained from the standard normal distribution table.

The z-score for a 95% service level is 1.645.

Substituting the given values in the formula, we get:

1.645 = (119 - 80) / σ

Solving for σ, we get:σ = (119 - 80) / 1.645

σ = 23.72
