Step-by-step explanation:

The main difference is that a Bimodal Histogram has two peaks representing the most frequent data values, whereas a Symmetric Histogram has one peak and its data is evenly distributed around a central value. In a symmetric histogram, mean, median, and mode coincide, unlike in a bimodal distribution, where the modes are different from the mean and median.

The difference between a Bimodal Histogram and a Symmetric Histogram relates to the distribution of data within the histogram.

A Bimodal Histogram has two distinct peaks or modes, indicating two prevalent data values within the dataset.

In contrast, a Symmetric Histogram is characterized by a single peak, with the data points arranged evenly around a central value such that it creates a mirror image on either side of the peak.

Symmetric histograms often indicate that the mean, median, and mode of the dataset coincide at the center of the distribution.

However, in a symmetric distribution with bimodality, the modes will differ from the mean and median.

When data is skewed to the left or right, it is not symmetric, and the mean, median, and mode do not align, with the mean being pulled towards the tail of the distribution in skewed datasets.

To visualize these concepts, one may create a histogram by plotting the frequency of data points against specified ranges.

Bimodal histograms will show two high-frequency areas, while symmetric histograms will show a single, central peak, indicating where the bulk of the data lies.

Answer:

90%

Step-by-step explanation:

If you are going to find out the percent of the car that do not have 4 wheel drive, you take the total amount of car that passed though the stoplight which is 100% . You take this 100% and then subtract the 10% to get the final answer 90%. 90% of the cars do not have 4 wheel drive.

To find the percentage of cars without four-wheel drive, subtract the percentage of cars with four-wheel drive from the total. Since 10% of cars have four-wheel drive, 90% do not.

If 10% of the cars have four-wheel drive, then the percentage of cars without four-wheel drive is the remainder when the total percentage (100%) is reduced by the percentage of those that do have four-wheel drive.

To calculate this, we subtract the percentage of cars with four-wheel drive from the total percentage:

100% - 10% = 90%

Therefore, 90% of the cars do not have four-wheel drive.

Let m be the no of trucks and n be the no of passenger vehicles...

Then m + n = 600

and 100m + 45n = 29200

Multiplying 1st equation by 45, we have 45m+45n=27000

then subtracting from 2nd eqn we have, 55m = 2200 that is m=40.Then n=560

So we have 40 trucks and 560 passenger vehicle

Answer:

14.1 in³

Step-by-step explanation:

Your expression for the volume was correct, except that it lacked units of measurement.

The volume is V = (1/3)π(1.5 in)²(6 in) = 14.1 in³

The volume of the cup will be 14.1 cubic inches. Thus, the correct option is B.

Let h be the height of the cone and A be the base area of the cone. Then the volume of the cone will be given as,

V = 1/3 × πr²h

A paper cup in the shape of an inverted cone is 6 inches tall and 3 inches in diameter.

The volume of the cup is calculated as,

V = 1/3 × π(1.5)²(6)

V = 14.1 cubic inches

Thus, the correct option is B.

Step-by-step explanation:

Mixed candy question... Skittles jar... to be filled with Jelly beans.

Let's first calculate the volume of the jar.  We'll assume it's a regular cylindrical prism jar, unlike the one on the photo which is narrower on top.

V = π * r² * h = π * (3.5)² * 11.5 = 140.875 π = 442.6 cubic cm

Now, we don't have the precise measurement of a jelly bean, but we know it's roughly 2-3 cubic cm.  The precision isn't needed to answer this question, just to have a rough idea... it's no 300 cu cm per jelly bean.

So, let's assume a 3 cu cm per jelly bean (2 cu cm wouldn't the final answer)....

442.6 / 3 = 147.5 jelly beans, approximately.

So, can they fit 100,000?  No

Can we fit 10,000 in there?  No

Can we fit 100?  Yes.

Can we fit 1?  Certainly

The explicit formula that will be used to find the cost of cleaning up d day oil spill is:

                  [tex]CoS(d)=532.5d+2[/tex]

The amount of oil, S, in tons, that has been spilled in d days is given by the function:

             S(d)=355d.

The cost to clean a t ton oil spill can be modeled by the function:

                       C(t)=1.5t+2

This means that the cost to clean in d days is given  by the composition function:    

 [tex]CoS(d)=C(S(d))\\\\\\i.e.\\\\\\CoS(d)=C(355d)\\\\\\i.e.\\\\\\CoS(d)=1.5(355d)+2\\\\\\i.e.\\\\\\CoS(d)=532.5d+2[/tex]        

A 5-day spill would cost approximately 2664.5 million dollars to clean up.

Cost of Cleaning Up an Oil Spill

To find an explicit expression that models the costs of cleaning up a d day oil spill, we need to connect the functions C(t) and S(d).

The cost function is given by:

C(t) = 1.5t + 2

The amount of oil spilled over d days is given by:

S(d) = 355d

First, substitute S(d) into the cost function where t represents the amount of oil spilled:

C(S(d)) = 1.5(355d) + 2

Simplify the expression:

C(d) = 532.5d + 2

Therefore, the explicit expression that models the costs of cleaning up a d day oil spill is C(d) = 532.5d + 2 (in millions of dollars).

Example

If the oil leakage lasts for 5 days, then the cost can be calculated as:

C(5) = 532.5(5) + 2 = 2662.5 + 2 = 2664.5 million dollars.

This shows the significant financial impact of prolonged oil spillage.

A study by economist Mark Cohen highlights the economic benefits of preventing oil spills, making more stringent environmental protection justified.

Answer:

your opponent made 59

Using the formula for calculating total points, we find out that the opponents won the basketball match by 1 point.

To find out who won the basketball match, we need to calculate the total points each team made. The formula to calculate total points is: (Number of 3-pointers * 3) + (Number of 2-point field goals * 2) + (Number of 1-point foul shots).

For your team: (10 * 3) + (8 * 2) + 12 = 30 + 16 + 12 = 58 points

For the opponents: (8 * 3) + (12 * 2) + 11 = 24 + 24 + 11 = 59 points

So, the opponents won the game. To find out by how many points they won, subtract the total points your team made from the opponents' total points: 59 - 58 = 1. Thus, the opponents won by 1 point.

The length of the tunnel is 2.8 kilometers.

Let's first convert the time taken to pass through the tunnel from minutes and seconds to seconds only.

2 minutes is equal to 2 * 60 = 120 seconds.

Adding the 30 seconds, the total time is 120 + 30 = 150 seconds.

We can calculate the speed of the train in meters per second using the formula:

Speed = Distance / Time

Given that the average speed of the train is 20 m/s, we can set up the equation as:

20 = (200 + L) / 150

Where L is the length of the tunnel in meters.

To find the length of the tunnel, we can solve this equation for L.

Multiplying both sides of the equation by 150, we get:

150 * 20 = 200 + L

3000 = 200 + L

Subtracting 200 from both sides, we have:

L = 3000 - 200

L = 2800 meters

Finally, to convert the length of the tunnel from meters to kilometers, we divide by 1000:

Length of the tunnel = 2800 / 1000 = 2.8 kilometers.

Therefore, the length of the tunnel is 2.8 kilometers.

We can only sum matrices with equal order, so we can't sum matrices A and B in the first exercise.

As for the second exercise, we have:

All of these answers depend on the fact that the sum/difference of two matrices is simply the sum/difference of the correspondent elements. So, if the element in the i-th row and the j-th column of A is [tex]a_{ij}[/tex] and the element in the i-th row and the j-th column of B is [tex]b_{ij}[/tex], we have

[tex]C=A+B\implies c_{ij} = a_{ij}+b_{ij}[/tex]

So, the sum between matrices inherits the properties of the sum between numbers: the order matters when you subtract (which is why a and f are false), the sum is commutative (which is why b, c, d are true) and associative (which is why e is true).

Subtracting vectors is akin to adding their opposites, and the operations are commutative and associative. Graphically, vector subtraction involves reversing a vector's direction before adding. Straight-line vector addition or subtraction simply depends on magnitudes and directions.

When dealing with adding and subtracting matrices or vector addition and subtraction, it's important to understand that these operations have straightforward rules. In particular, subtracting vectors can be interpreted as adding vectors in the opposite direction - this is analogous to scalar subtraction, such as how 5 - 2 can be thought of as 5 + (-2). Graphically, this means that when subtracting vectors, you essentially reverse the direction of the vector being subtracted and then perform vector addition as you would normally.

Mathematically, the vector addition is associative and commutative, and these properties extend to matrix addition as well. Likewise, multiplying vectors or matrices by scalars follows the distributive property. In a practical sense, when vectors are aligned on a straight line, adding or subtracting them is simplified since you only need to consider their magnitudes and directions along that line.

Answer:

The answer is the attached figure

Step-by-step explanation:

* Lets revise the equation of the circle

- The center-radius form of the circle equation is

  (x – h)² + (y – k)2 = r², where the center is the point (h, k)

  and the radius is r.

- This form of the equation is helpful, since you can easily find the

  center and the radius.

* Now lets solve the problem

- The equation of the circle is (x + 2)² + (y - 0.5)² = 16

* Lets compare it with form above

∵ (x - h)² = (x + 2)²

∴ -h = 2 ⇒ × -1

∴ h = -2

∵ (y - k)² = (y - 0.5)²

∴ -k = -0.5 ⇒ × -1

∴ k = 0.5

∴ The center of the circle is (-2 , 0.5)

∵ r² = 16 ⇒ take √ for both sides

∴ r = √16 = 4

∴ The radius of the circle is 4 units

* Now lets look to the answer to find the circle whose center is

 (-2 , 0.5) and radius 4 units

∴ The answer is the attached figure

* From the graph:

- The center of the circle is (-2 , 0.5)

- The horizontal diameter is between -6 and 2, then the length

 of the diameter = 2 - -6 = 8

∵ The radius = 1/2 the diameter

∴ The raduis = 1/2 × 8 = 4 units
