Answer:

18 cm for larger base

Step-by-step explanation:

For similar figures, there is a formula regarding volume, area, and length

Large: small =  y: x   for length

large: small = (y^3) / (x^3)  for volume

729 cm cube/ 64 cm cube  = large : small

9: 4  = large: small  by length

large/ 8cm = 9/ 4

large = 8*(9/4) = 2*9 = 18 cm

If all of the dimensions of the tank are doubled, since we live in three dimensions, the volume of the new tank will be [tex]2^3=8[/tex] times as large. [tex]8\cdot 2000=16000[/tex] feet, or answer choice A. Hope this helps!

Answer:

A 16,000 ft³

Step-by-step explanation:

Let's say the dimensions were 2, 10, and 100 now if you double those, it becomes 4, 20, 200 which equals 16,000.

Now let's say the dimensions were 2, 4, 250 double the dimensions again and it becomes 4, 8, 500 which equals 16,000.

So no matter what the dimensions are, the volume will be 16,000.

Answer:

The probability of a selected car being a 4 door car, given that the car has a sunroof = 0.40

Step-by-step explanation:

The complete question is presented in the attached image.

The conditional probability, of event A happening, given that event B has happened, P(A|B), is given mathematically as

P(A|B) = P(A n B) ÷ P(B)

So, the required probability of a selected car being a 4 door car, given that the car has a sunroof is given as

P (4 doors | sunroof)

= P (4 doors n sunroof) ÷ P(sunroof)

Note that the probability of an event is given as the number of elements in that event divided by the Total number of events.

P (4 doors n sunroof)

= n (4 doors n sunroof) ÷ n (total)

From the Venn Diagram in the attached image,

n (4 doors n sunroof) = 20 + 0 = 20

n (total) = 100

P (4 doors n sunroof) = (20/100) = 0.20

P(sunroof) = n(sunroof) ÷ n(total)

n(sunroof) = 12 + 18 + 20 + 0 = 50

n(total) = 100

P(sunroof) = (50/100) = 0.50

P (4 doors | sunroof)

= P (4 doors n sunroof) ÷ P(sunroof)

= (0.20/0.50) = 0.40

Hope this Helps!!!

To find the probability of a car having 4 doors given that it has a sunroof, we use conditional probability. The probability can be found by dividing the number of cars with both a sunroof and 4 doors by the total number of cars with a sunroof. In this case, the probability is 6/11.

To find the probability of a car having 4 doors given that it has a sunroof, we need to use the conditional probability formula, which is:

P(4 doors | sunroof) = P(4 doors and sunroof) / P(sunroof)

In this case, we know that 11 cars have a sunroof, 6 cars have 4 doors, and a total of 100 cars are parked at the business. Therefore:

P(4 doors and sunroof) = 6/100

P(sunroof) = 11/100

Substituting these values into the conditional probability formula, we get:

P(4 doors | sunroof) = (6/100) / (11/100)

Simplifying the expression gives us:

P(4 doors | sunroof) = 6/11

Therefore, the probability that a randomly selected car with a sunroof has 4 doors is 6/11.

Answer:

d) 16%

Step-by-step explanation:

The empirical rule states that for a normal distribution population with a mean (μ) and standard deviation (σ), the following conditions occur:

Given μ = 16 ounce and σ = 0.05 ounce.

68% falls within one standard deviation = μ ± σ = 16 ± 0.05 = (15.95, 16.05)

the number that falls outside one standard deviation = 100% - 68% = 32%

Therefore percentage of boxes have weights that are more than 1 standard  deviation above the mean = 32% / 2 = 16%

Approximately 32% of boxes have weights that are more than 1 standard deviation above the mean.

To find the percentage of boxes that have weights more than 1 standard deviation above the mean, we can use the Empirical Rule. According to the Empirical Rule, approximately 68% of the data falls within 1 standard deviation of the mean, 95% falls within 2 standard deviations, and 99.7% falls within 3 standard deviations.

Since we want to find the percentage of boxes that have weights more than 1 standard deviation above the mean, we can subtract 68% from 100% to get 32%. So, the answer is 32%.

pi * 8.7^2 * 27.8

calculate that:

pi * 75.69 * 27.8

2104.182 * pi

or

6610.13148

Apologies in advance if I explain things badly or get the wrong answer. :/

Final answer:

The volume of the display stand, which is a cylinder with a radius of 8.7 cm and a height of 27.8 cm, is approximately 6612.105 cubic centimeters.

Explanation:

To calculate the volume of the cylinder that is being used as a display stand, we will use the formula for the volume of a cylinder, which is V = πr²h. Here, 'V' stands for volume, 'r' is the radius of the cylinder's base, 'h' is its height, and π (pi) is a constant, which we can approximate to 3.14159.

Given:

Now, let's substitute these values into our formula:

V = π(8.7 cm)²(27.8 cm)

V = 3.14159 × (75.69 cm²) × 27.8 cm

V = 3.14159 × 2105.782 cm²

V = 6612.105 cm³ (rounded to three decimal places)

Therefore, the volume of the display stand is approximately 6612.105 cubic centimeters (cm³).

Answer:  The slant height of the cone is 65.6 m

Step-by-step explanation:

Given: The diameter of a cone = 10 m

Surface area of cone = 190.6 m²

To find: Slant height

Diameter of cone = 10 m

Therefore Radius of cone = [tex]\dfrac{\text {Diameter }}{2} = \dfrac{10}{2} =5m[/tex]

As we know that surface area of a cone is given by

[tex]S.A. = \pi r(l+r)[/tex]

Where S.A. is surface area , r is the radius of cone and l is the slant height of the cone.

Let Slant height = l

So we have

[tex]190.6 = \dfrac{22}{7} \times 5 ( 5+l)\\\\\Rightarrow 5+l= \dfrac{190.6 \times 7}{22}\\\\\Rightarrow l= \dfrac{1334.2}{22}+5\approx 60.64+5 = 65.64\approx65.6[/tex]

Hence the slant height of the cone is 65.6 m

Hey there!

First of all, let's count the sides that we can count.

Our shortest side is 8 units if you count the squares it covers.

Now we can do our other side, which is 15 units when you count.

Now, we need to find our third side, which is the longest. The longest side is the hypotenuse. Because this triangle is a right triangle (it has a ninety degree angle), we can use the Pythagorean Theorem to solve for this side.

The Pythagorean Theorem states that when a triangle is a right triangle, [tex]a^{2} +b^{2} =c^{2}[/tex], where a and b represent the legs, and c represents the hypotenuse.

So, what we will do now is take the sides we have and solve for our c.

[tex]8^{2} +15^{2} =c^{2} \\64+225=289=c^{2} \\c=\sqrt{289} \\c=17[/tex]

As you can see, we used the square root to undo the squared c.

Now, we add our three lengths to get our perimeter.

8+15+17=40

Therefore, our perimeter is 40 units.

I hope that this helps you! Have a wonderful day!

Answer:

Height of the oblique prism is 18 units.

Step-by-step explanation:

Volume of an oblique prism = [tex]\frac{1}{3}(\text{Area of the base})(\text{Perpendicular height})[/tex]

Area of the base of this prism = 24 square units

And volume of the prism = 144 cubic units

By substituting these values in the formula,

144 = [tex]\frac{1}{3}(24)(h)[/tex]

h = [tex]\frac{144\times 3}{24}[/tex]

h = [tex]\frac{432}{24}[/tex]

h = 18 units

Therefore, height of the oblique prism is 18 units.

To predict the resting heart rate of a person who exercises 8 hours per week, you can find the corresponding point on the scatter plot that represents 8 hours of exercise and read off the corresponding resting heart rate value.

A scatter plot is used to show the relationship between two sets of data. In this case, Ben collected data on the resting heart rate and average hours of exercise per week for 12 people. Based on the scatter plot, we can make a prediction of the resting heart rate for a person who exercises an average of 8 hours per week. To do this, we can find the point on the scatter plot that corresponds to an average of 8 hours of exercise per week and then determine the corresponding resting heart rate.

Let's find the point on the scatter plot that represents an average of 8 hours of exercise per week.

Once you have the corresponding point, you can read off the resting heart rate value in beats per minute.

P(2, then 2)  = [tex]\frac{1}{36}[/tex]

P(3, then 5) = [tex]\frac{1}{36}[/tex]

P(4, then odd) = [tex]\frac{1}{12}[/tex]

Step-by-step explanation:

Given: A fair number cube is rolled

To find: P(2, then 2) , P(3, then 5) , P(4, then odd)

Solution:

Probability refers to chances of occurrence of some event.

Probability = Number of favourable outcomes/Total number of outcomes

Sample space = [tex]\left \{ 1,2,3,4,5,6 \right \}[/tex]

Total number of outcomes = 6

P(2, then 2)  = P(2)P(2) = [tex]\frac{1}{6}(\frac{1}{6})=\frac{1}{36}[/tex]

P(3, then 5) = P(3)P(5) = [tex]\frac{1}{6}(\frac{1}{6})=\frac{1}{36}[/tex]

Odd numbers out of the sample space = [tex]\left \{ 1,3,5 \right \}[/tex]

P(4, then odd) = P(4)P(odd) = [tex](\frac{1}{6})(\frac{3}{6} )=\frac{1}{12}[/tex]

To calculate the probability of rolling specific numbers on a fair, six-sided die, multiply the probabilities for each individual roll. P(2, then 2) and P(3, then 5) are both 1/36. P(4, then odd) is calculated as P(4) multiplied by the combined probability of rolling an odd number, resulting in 1/12.

Understanding Probability with a Fair Number Cube:

When rolling a fair, six-sided die, each outcome has an equal probability of occurring. Specifically, the probability (P) of any one number, such as a 2 or a 3, is 1/6 since it is a fair die. When considering sequential rolls, we have to calculate the probability of each event happening one after another, which involves multiplying the probabilities of the individual events.

Thus, to find the probability of rolling specific numbers or combinations on a number cube, you can calculate each probability separately and then combine them as needed using multiplication.
