Lihle would need 30 liters of milk to make 120 cupcakes.

To determine the amount of milk Lihle needs to make 120 cupcakes, we can calculate the total milk requirement by multiplying the milk quantity per cupcake by the number of cupcakes.

Given that the recipe requires 250 milliliters (ml) of milk per cupcake, we can proceed with the calculation:

Convert milliliters to liters:

Since there are 1,000 milliliters in a liter, we divide 250 ml by 1,000 to get the milk quantity per cupcake in liters, which is 0.25 liters.

Multiply the milk quantity per cupcake by the total number of cupcakes: Multiply 0.25 liters (milk per cupcake) by 120 cupcakes.

0.25 liters/cupcake \(\times\) 120 cupcakes = 30 liters.

Therefore, Lihle would need 30 liters of milk to make 120 cupcakes in a US curriculum class.

It's important to note that this calculation assumes the given milk requirement of 250 milliliters per cupcake and does not consider any other ingredients or variations in the recipe.

The ratio of the circumference of a circle with radius r to its area is 2:r or 2 to r.

A circle is a two-dimensional shape that is defined as the set of all points in a plane that are at a fixed distance, called the radius, from a given point, called the center. The distance around the circle is called the circumference, and the distance across the circle passing through the center is called the diameter.

The circumference of a circle with radius r is given by the formula:

C = 2πr

The area of a circle with radius r is given by the formula:

A = π×r²

Therefore, the ratio of the circumference of a circle with radius r to its area is:

C/A = (2πr) / (πr²)

Simplifying the expression by canceling out π and r from the numerator and denominator, we get:

C/A = 2/r

Therefore, the ratio of the circumference of a circle with radius r to its area is 2:r or 2 to r.

The complete question is:

Find the following ratio.

The ratio of circumference of circle with radius r to its area.

Answer:

m = 20

b = 25

Step-by-step explanation:

25 is the 'y interpret' which does not change as the hours go on

20 is the 'slope' which refers to a change in value with each increasing hour

Answer:

20=m

25=b

Step-by-step explanation:

This is because

y=mx+b

and 20 is the slop and 25 is the y intercept

Answer:

14/25

Step-by-step explanation:

If the denominators are the same, subtract the numerators.

21/25-7/25=14/25

14 and 25 do not have any similar factors greater than 1, so we keep it as 14/25.

A 90% confidence interval estimate of the population standard deviation is 1596.45-4466.73

We can use the chi-square distribution to construct a confidence interval for the population standard deviation, where the lower and upper limits are given by:

\(\sqrt{(n-1)*s^2/chi2(alpha/2,n-1)) }\)         and \(\sqrt{(n-1)*s^2/chi2(1-alpha/2,n-1)}\)

Standard Deviation is a measure that shows how much variation (such as spread, dispersion, spread,) from the mean exists.

Where n is the sample size, s is the sample standard deviation, alpha is the significance level, and chi2 is the chi-square distribution function.

Substituting the given values, we get:

Lower limit

= \(\sqrt{(31-1)*50^2/chi2(0.05/2,31-1)}\)

= 1596.45

Upper limit

= \(\sqrt{(31-1)*50^2/chi2(1-0.05/2,31-1)}\)

= 4466.73

Therefore, a 90% confidence interval estimate of the population standard deviation is 1596.45-4466.73.

Hence, the correct answer is B) 1596.45-4466.73

All the numbers other than prime numbers are composite numbers.

The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.

Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.

Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables

Therefore, 6 tables are required.

Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.

Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.

Thus, each prime number attender should serve 3 customers each.

Try the desmos graphing calculator:

Step-by-step explanation:

On solving the equation for the given situation, there are \(140\) cars in the train.

Let the total number of cars in the train be \(x\).

Half of the cars on a train are flat cars.

So, number of flat cars \(= \frac{x}{2}\).

The train has half as many coal cars as flat cars.

So, number of coal cars \(= \frac{x}{4}\).

The train has one-fifth as many passenger cars as coal cars.

So, number of passenger cars \(= \frac{x}{4}\times \frac{1}{5}=\frac{x}{20}\).

Other cars \(= 28\).

Now, according to question,

\(x=\frac{x}{2}+\frac{x}{4}+\frac{x}{20}+28\)

\(x=\frac{10x+5x+x}{20}+28\)

\(x=\frac{16x}{20}+28\)

\(x-\frac{16x}{20}=28\)

\(\frac{20x-16x}{20}=28\)

\(\frac{4x}{20}=28\)

\(\frac{x}{5}=28\)

\(x=28\times 5\)

\(x=140\)

So, there are \(140\) cars in the train.

These values represent the range within which the middle 30% of indoor cats' age of death lies.

a. The distribution of X is a normal distribution, denoted as X ~ N(μ, σ), where μ represents the mean age at death of indoor cats and σ represents the standard deviation.

b. To find the probability that an indoor cat dies when it is between 11 and 14.6 years old, we need to calculate the area under the normal distribution curve between these two values.

First, we need to standardize the values by subtracting the mean and dividing by the standard deviation. Let's call the standardized values z1 and z2.

z1 = (11 - μ) / σ
z2 = (14.6 - μ) / σ

Using the z-table or a statistical calculator, we can find the corresponding probabilities for these standardized values. The difference between these two probabilities will give us the probability of the cat's age at death being between 11 and 14.6 years old.

Let's say the probability for z1 is P1 and the probability for z2 is P2. Then, the probability we're looking for is P2 - P1.

c. The middle 30% of indoor cats' age of death lies between the lower and upper percentiles. To find these percentiles, we need to locate the z-scores that correspond to the lower and upper percentages.

First, let's find the z-scores for the lower and upper percentiles. The lower percentile will be (1 - 0.30) / 2 = 0.35, and the upper percentile will be 1 - (1 - 0.30) / 2 = 0.65.

Using the z-table or a statistical calculator, we can find the z-scores corresponding to these percentiles. Let's call the lower z-score zL and the upper z-score zU.

zL corresponds to the 0.35 percentile, and zU corresponds to the 0.65 percentile.

Now, we can find the values for the lower and upper percentiles using the z-scores, mean, and standard deviation.

Lower percentile = μ + zL * σ
Upper percentile = μ + zU * σ

Sorry if it is wrong

Aisha and Jordan need 63 carpet tiles to cover the maximum amount of floor with the whole tiles.

To find the area of the greatest amount of floor that can be covered with carpet tiles, we need to figure out how many tiles can fit in that area. Since each tile has a side length of 1.5 feet, we can divide the grid into squares with side lengths of 1.5 feet to see how many tiles can fit.

Dividing the grid in this way, we can see that the area of each square is 2.25 square feet (1.5 ft x 1.5 ft). To find the maximum area that can be covered with whole tiles, we need to find the dimensions of the largest rectangle that can be formed using these squares.

In the grid, the longest side that can be formed using whole tiles is 9 squares long (13.5 feet), and the shortest side that can be formed using whole tiles is 7 squares long (10.5 feet). Therefore, the maximum area that can be covered with whole tiles is:

Area = Length x Width = 13.5 ft x 10.5 ft = 141.75 square feet

To find out how many tiles are needed to cover this area, we need to divide the area by the area of each tile:

Number of tiles = Area / Area of each tile = 141.75 sq ft / 2.25 sq ft per tile = 63 tiles

Therefore, Aisha and Jordan need 63 carpet tiles to cover the maximum amount of floor with the whole tiles.

The function with y-intercept as 1 is h(x) = 0.5(2)ˣ + 0.5.

The y-intercept is the point where the graph intersects the y-axis. In other words, the y-intercept of a function is the value of y when x = 0.

Therefore, let's find the function with y-intercept as 1.

Hence,

h(x) = 0.5(2)ˣ + 0.5

Let's make x = 0 to check if the value of y = 1

Therefore,

h(x) = 0.5(2)ˣ + 0.5

h(0) = 0.5(2)⁰ + 0.5

h(0) = 0.5(1) + 0.5

h(x) = 0.5 + 0.5

I suppose you mean

Let \(x=1\) and \(y=0\). Then

\(f(1) f(0) = f(1 + 0) + f(1 - 0) \implies f(1) f(0) = 2 f(1) \implies f(0) = 2\)

Now if we fix \(y=1\), the functional equation reduces to the recurrence relation

\(f(x) f(1) = f(x + 1) + f(x - 1) \implies f(x+1) - 3f(x) + f(x-1) = 0\)

and we can find \(f(7)\) with a few rounds of substitution.

\(x=1 \implies f(2) - 3f(1) + f(0) = 0 \implies f(2) = 3f(1) - f(0) = 7\)

\(x=2 \implies f(3) - 3f(2) + f(1) = 0 \implies f(3) = 3f(2) - f(1) = 18\)

\(x=3 \implies f(4) - 3f(3) + f(2) = 0 \implies f(4) = 3f(3) - f(2) = 47\)

\(x=4 \implies f(5) - 3f(4) + f(3) = 0 \implies f(5) = 3f(4) - f(3) = 123\)

\(x=5 \implies f(6) - 3f(5) + f(4) = 0 \implies f(6) = 3f(5) - f(4) = 322\)

The distance between the tops of the buildings is 28.5 meters.

To find the distance between the top of the buildings, we can use the concept of similar triangles.

Let's denote the height of the shorter building as "a" (12 m) and the height of the taller building as "b" (19 m). The distance between the buildings can be denoted as "c" (18 m), and the distance between the top of the buildings as "x" (which we need to find).

We can set up a proportion based on the similar triangles formed by the buildings:

a/c = b/x

Substituting the known values:

12/18 = 19/x

To find "x," we can cross-multiply and solve for "x":

12x = 18 * 19

12x = 342

x = 342/12

x = 28.5 m

Therefore, the distance between the tops of the buildings is 28.5 meters.
