Step-by-step explanation:
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.
Two triangular pyramids are similar the volume of the large pyramids is 729cm and the volume of the smaller pyramids is 64 cm . If the perimeter of the base of the similar pyramids is 8 cm what is the perimeter of the base of the larger pyramids
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

Given that a randomly selected car has a sunroof, find the probability the car has 4 doors.
P (4 doors | sunroof) =
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.
Explanation: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.

What is the perpendicular height of an oblique prism with a volume of 144 cubic units and an area of 24 square units
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.

If a cone with a diameter of 10 m has a surface area of 190.6m2, find its slant height. Round to the nearest tenth.
Slant Height = m
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

1. P(3, then 5)
3. P(4, then odd)
Answer:
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.
P(2, then 2) = P(2) * P(2) = (1/6) * (1/6) = 1/36.P(3, then 5) = P(3) * P(5) = (1/6) * (1/6) = 1/36.P(4, then odd) involves the probability of rolling a 4 first, and then an odd number, which could be a 1, 3, or 5. The probability for each odd number is 1/6, and since there are three odd numbers, the combined probability of rolling an odd number is 3/6 or 1/2. Therefore, P(4, then odd) = P(4) * P(odd) = (1/6) * (1/2) = 1/12.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.

Ben collected data from a group of 12 people. He measured each persons resting heart rate and recorded the average number of hours each person exercised per week. He created a scatter plot to show the data he collected. Based on the scatter plot, what is the best prediction of the resting heart rate, in beats per minute, of a person who exercises an average of 8 hours each week?
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.
Explanation: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.
Find the x-coordinate of the point on the scatter plot that corresponds to 8 hours of exercise per week (horizontal axis).From the x-coordinate, find the corresponding y-coordinate (vertical axis), which represents the resting heart rate.Once you have the corresponding point, you can read off the resting heart rate value in beats per minute.

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:
Radius (r) = 8.7 centimetersHeight (h) = 27.8 centimetersNow, 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).

The weights of boxes of a certain brand of pasta follow an
approximately normal distribution with a mean of 16 ounces and a standard
deviation of 0.05 ounces.
What percentage of boxes have weights that are more than 1 standard
deviation above the mean? (Use the Empirical Rule 68, 95, 99.7)
a) 15%
b) 14%
c) 20%
d) 16%
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:
68% falls within one standard deviation μ ± σ95% falls within two standard deviation μ ± 2σ99.7% falls within three standard deviation μ ± 3σGiven 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.
Explanation: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%.

What is the perimeter of the triangle?
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!
