As per the unitary method, the place of marks in the water level in the cooler is 2.0 and 2.2 respectively.

Here we have given  cooler contains 4 l of water. the cooler has marks on it at every 0.2 l.

And here we also know that water bottles are filled with water from the cooler, and each bottle holds approximately 4/9 l.

Then the marking on the cooler are written as 0.2, 0.4, 0.6, 0.8, ...

Here we know that the water bottle will hold 4/9l of water

Here we have to convert the fraction into decimal form, then we get,

=> 4/9

=> 0.44

Then the water that can be filled on 4 bottle is calculated as,

=> 4 x 0.44

=> 1.76

Then the remaining water is calculated as,

=> 4 - 1.76

=> 2.24

Then the level of water mark in the cooler is 2.0 and 2.2

Step-by-step explanation:

y = 9 is the same as (0, 9)

Answer:

y = x + 5

Step-by-step explanation:

You can see that x is increasing at exactly the same rate as y. That rate is 1. This gives the graph a slope of 1. Now we can determine by subtracting 1 from y when x = 1 that the y intercept is 5. Slope intercept is y = mx+b. The y intercept is b which is five and the slope is m which is one.

The reason why parallel line is so important in our everyday lives is that help us to understand the path of the objects and sides of the various shapes.

Because they allow us to construct congruent angle pair relationships, parallel lines and transversals are crucial to the study of geometry.

If the true mean of this group's wages is also $7.00 and the standard deviation is $0.50, then the average of a sample of n workers has the same mean and a standard deviation of (pop. stan. dev. / √n).

In this case, the sample average is a random variable with a mean of $7.00 and a standard deviation of $0.50/√64 = 0.0625.

If a random variable has a normal distribution with a mean $7.00 and st. dev. $0.0625, then the probability of observing it as $6.90 or less is:

P[sample mean < 6.90] = P[z < (6.90 - 7.00)/0.0625] = P[z < -1.6] = 0.0548.

From the values in "a", we can tell there is no good agreement between the given values, and just one (87.1) value is near to the true value. So a is neither precise nor accurate.

From the values in "b", we can tell these given values are reasonably close to the true value and exhibit good agreement. So b is precise and accurate.

Answer:

The sunflower is 28 inches tall after 9 weeks

The sunflower is 2w + 10 tall after w weeks

Step-by-step explanation:

We know

The sunflower was 10 inches tall, growing at a rate of 2 inches per week. Let's T represent the tall of the sunflower; we have the equation

t = 2w + 10

How tall would the sunflower be after 9 weeks?

t = 2(9) + 10

t = 28 inches

How tall would the sunflower be after w weeks?

t = 2(w) + 10

t = 2w + 10

So,

The sunflower is 28 inches tall after 9 weeks

The sunflower is 2w + 10 tall after w weeks

Suppose that the line considered be of the form  y=f(x)

The equation for y-axis is x = 0

Thus, intersection between both the curves is obtained by putting x = 0 in the considered function.

We get x=0 and y=f(0)

Thus, the coordinate point of intersection with y-axis is (0,f(0))

And the equation for x-axis is y=0

Thus, its intersection with given function is at y= 0 and y such that

We are trying to find the number of ways to distribute 15 distinguishable objects into five distinguishable boxes so that each box has 1, 2, 3, 4, and 5 objects in them, respectively.

We can use the formula for combination to solve this problem. The number of ways to distribute n distinct objects into r distinct boxes where the first box has k1 objects, the second box has k2 objects, ..., and the last box has kr objects is:

n! / (k1! * k2! * ... * kr!)

Where n! is the factorial of n, k1! is the factorial of k1 and so on.

In this case, we have 15 distinct objects and 5 distinct boxes where the first box has 1 object, the second box has 2 objects, the third box has 3 objects, the fourth box has 4 objects, and the fifth box has 5 objects.

So, the number of ways to distribute 15 distinguishable objects into five distinguishable boxes so that the boxes have one, two, three, four, and five objects in them, respectively is:

What is co-ordinate ?

In mathematics, a coordinate is a pair of numerical values that represent a specific location on a two-dimensional surface, such as a graph, a map, or an image. The two values are usually referred to as the x-coordinate and the y-coordinate.

A path from (0,0) to (85,65) on the integer grid that starts at (0,0) and increments one coordinate by 1 and leaves the other unchanged at each step is equivalent to a sequence of 85 "right" steps and 65 "up" steps. The number of ways to arrange these steps is given by the binomial coefficient C(85+65, 85), which is the number of ways to choose 85 items (the "right" steps) from a set of 150 items (85 "right" and 65 "up" steps) without replacement and where order matters.

The general formula for the binomial coefficient is C(n, k) = n! / (k!(n-k)!), where n! is the factorial of n, i.e., the product of all integers from 1 to n, and k! is the factorial of k. Using this formula, we have:

C(150, 85) = 150! / (85!(150-85)!) = (150149148*...6665) / (858483*...1) = (150149148...6665) / (85!)

The specific heat shows that Substance Y has more atoms per gram than substance W.

Specific heat:

Specific heat is a property of a substance that describes how much heat energy is required to raise the temperature of a certain amount of that substance by one degree. It is typically measured in units of joules per gram per degree Celsius (J/g°C).

Different substances have different specific heats. For example, water has a relatively high specific heat of 4.18 J/g°C, which means that it takes a lot of heat energy to raise the temperature of water by one degree. This is why water is often used as a coolant or in air conditioning systems, as it can absorb a large amount of heat energy without experiencing a significant temperature change.

Therefore, the specific heat shows that Substance Y has more atoms per gram than substance W.

The shortest distance between points A and B on the cylinder is 6 inches.

This problem uses the Pythagorean Theorem to calculate the shortest distance between points A and B. The Pythagorean Theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

In this problem, the hypotenuse is the shortest distance between points A and B and the other two sides are the radius and height of the cylinder.

Step 1: Calculate the radius of the cylinder by dividing the circumference of the base (18 inches) by 2π (3.14159):

r = 18 inches / 2π = 2.827 inches

Step 2: Calculate the height (h) of the cylinder by subtracting the radius from the total height (12 inches):

h = 12 inches - 2.827 inches = 9.173 inches

Step 3: Calculate the shortest distance between points A and B by multiplying the height (h) by 2:

d = 9.173 inches x 2 = 18.346 inches

Step 4: Round the result to the nearest whole number:

d = 18.346 inches ≈ 6 inches
