Hi there!!

Your answer is:

Each side is 3 inches.

Step-by-step explanation:

The volume of a cube is equal to l×w×h. All sides of a cube are the same size!

If x^3 = 27, then work backwards!

1: Take the cubed root of 27.

The cubed root of 27= 3!

2: Check your work!

If the length, width, and height is all 3 units, plug in 3 and solve. If both sides equal each other, you are correct

3×3×3 = 27 ?

9×3 = 27 ?

Answer:

16.5 cm²

Step-by-step explanation:

the measure of an exterior angle (32°) is found by dividing the difference between the measures of the intercepted arcs (54° and arc abject BF) by two.

32 = (BF - 54)/2

64 = BF - 54

arc angle BF = 64 + 54 = 118°

the area of that sector is

pi×r² × 118/360 = pi×4² × 118/360 = pi×16 × 118/360 =

= pi×2 × 118/45 =

Step-by-step explanation:

To find the mean, add all the numbers up and divide by the sum of the number values, in this case it would be 34 divided by 11 which gives us 31. I don’t have a great definition for standard deviation but you could probably look one up at find it easily.

In the next 10 years there will be 398 racoons in the state park

The annual increase in the population size is defined as a sum of differences: the difference between births less deaths and the difference between immigrants less emigrants, in a given country, territory or geographic area at a given year.

Using the formula

p(t) = p(o) e^ kt

k = 3.5/100 = 0.035

t = 10 years

p(t) = 280 e^ 0.035 ×10

p(t) = 280e^0.35

p(t) = 280 × 1.42

p(t) = 398( nearest whole number)

therefore be after 10 years there will be 398 racoons in the state park.

The smallest measurement used in the apothecary system for volume is the minim.

The apothecary system is an outdated system of measurements primarily used in pharmacy and medicine. It includes various units for measuring volume, weight, and other quantities.

In the apothecary system, the minim is the smallest unit of measurement for volume. It is equivalent to approximately 0.0616 milliliters.

The minim is a small unit of measurement and is typically used for precise dosing of liquids in the apothecary system. It is commonly used in pharmaceutical compounding and in the preparation of medications.

However, it's important to note that the apothecary system is no longer widely used in modern healthcare practices. The metric system, with units such as milliliters and liters, has become the standard for measuring volume in most countries.

Answer:

b = 99°

Step-by-step explanation:

XY is a line segment and so it is a straight line which means that it is a straight angle - 180°

a = 28°

c = 53°

b = ?

=> a + b + c = 180°

=> 28° + b + 53° = 180°

=> b = 180° - (53 + 28)°

=> b = 180° - 81°

=> b = 99°

Therefore b = 99°

The set of the whole numbers is the set of all the positive integers and the zero. So we can write it as:

{0, 1, 2, 3, 4, ...}

We will see that:

if k is a whole number, then there are k whole numbers that are smaller than k.

Let's see how we got that:

Now, we know that k is a whole number, then just let's assign different whole numbers to k and count how many whole numbers are smaller than k.

if k = 1

We have 1 whole number smaller than k, that is the zero.

if k = 2

We have 2 whole numbers smaller than k, the zero and the 1.

if k = 3

we have 3 whole numbers smaller than k, {0, 1, 2}

We already can see the pattern.

if k is a whole number, then there are k whole numbers that are smaller than k.

Answer:

58°

Step-by-step explanation: Nick was able to view the museum painting through the mirror due to reflection. The painting was reflected after hitting the plane mirror. According to the law of reflection, the angle of incidence is equal to the angle of reflection. The incident angle is the angle which the incident ray( the ray which strikes or hits the plane mirror) makes with the normal(line perpendicular to the tangent).

Thus, the angle which the painting makes with the mirror is equal to the angle at which the painting is being viewed = 58°.

Answer:

Percent error is approx. 22%

Step-by-step explanation:

So to do this you need to know the formula for percent error, which is

percent error = l measured - theoretical / theoretical l * 100%

With this just plug in 18 (real) and 14 (measured).

percent error = l 14 - 18 / 18 l * 100%

percent error = l -4 / 18 l *100%

percent error = l -2/9 l *100%

You then do absolute value because the percent error must be positive not negative! So -2/9 becomes 2/9. You then divide 2/9 to get approx. 0.22... and you muliply by 100% to get 22%.

Step-by-step explanation:

To find the probability that a randomly selected American over the age of 18 drinks coffee in the morning or has cereal for breakfast, we can use the formula:

P(C or B) = P(C) + P(B) - P(C and B)

where:

P(C) = the probability of drinking coffee in the morning

P(B) = the probability of having cereal for breakfast

P(C and B) = the probability of doing both

From the problem, we know that:

P(C) = 0.65

P(B) = 0.25

P(C and B) = 0.10

Plugging these values into the formula, we get:

P(C or B) = 0.65 + 0.25 - 0.10

P(C or B) = 0.80

Therefore, the probability that a randomly selected American over the age of 18 drinks coffee in the morning or has cereal for breakfast is 0.80, or 80%.

There is no graph provided for reference, but if the graph shows a probability distribution, then the probabilities that are equal to 0.3 would depend on the specific shape and values displayed on the graph.

Without this information, it is impossible to determine which probabilities are equal to 0.3. Based on the given information, the graph represents a probability distribution. To determine which probabilities are equal to 0.3, you would need to analyze the graph (which is not provided). However, I can explain each term:
1. p(5≤x≤8): This represents the probability that x falls between 5 and 8, inclusive.
2. p(x≤3): This denotes the probability that x is less than or equal to 3.

Answer:

P = 16x+26y units

Step-by-step explanation:

Let the length is (x+8y) units

Width = (8x-x+5y) units

We need to find the perimeter. We know that the perimeter is equal to the sum of all sides.

P = 2[(x+8y) + (8x-x+5y)]

= 2[(8x+8y+5y)]

= 2[8x+13y]

= 16x+26y

Hence, the required perimeter is 16x+26y.

The z-score for a class with 16 students is  -1.70

The z-score for a class with 16 students in the business school of the particular university is approximately -1.22.

To calculate the z-score, we can use the formula:

z = (x - μ) / σ

Where:

x is the value we want to calculate the z-score for (in this case, the class size of 16),

μ is the mean (average) class size,

σ is the standard deviation.

Given that the average class size is 39.1 students (μ = 39.1) and the standard deviation is 13.6 students (σ = 13.6), we can substitute these values into the formula:

z = (16 - 39.1) / 13.6

Simplifying the equation, we have:

z = (-23.1) / 13.6

Dividing -23.1 by 13.6, we get approximately -1.70. Therefore, the z-score for a class with 16 students is approximately -1.70.

Answer:

Explanation:

When you use absolute value "|n|" whatever is inside the equation has it's absolute value which means even if it is a negative it comes out positive when using absolute value. But in this case there is a negative in front of the absolute value sign which basically means the same thing just a negative answer. So by following order of operations you do the absolute value first which would leave you with "5-2". The 5 is positive because the negative absolute value cancelled out the negative in front of the 5 and made the 5 positive. The 2 is negative because the negative absolute value cancelled out the positive and made it a negative. The last step is simple subtraction which would leave you with -3.

To find the probability that the amount of pollutant in a given sample will exceed 1/2 for the smokestack with the filter installed, you need to determine the distribution of the pollutant levels and then calculate the probability based on that distribution.

To find the probability that the amount of pollutant in a given sample will exceed 1/2 when a filter is installed in the smokestack, we need to use the information provided in the question. However, we do not have any specific information on the distribution of the pollutant levels, so we cannot calculate the exact probability.
Instead, we can make some assumptions based on the purpose of the filter. Filters are typically installed to reduce the amount of pollutants emitted into the air, so it is reasonable to assume that the filter will decrease the amount of pollutant in each sample. Therefore, we can expect the probability of the pollutant level exceeding 1/2 to decrease when a filter is installed.
Without more information, we cannot give an exact probability, but we can say that it is likely lower than the probability without a filter. We would need to know more about the specific characteristics of the filter and the pollutant to make a more accurate estimate.
