Which describes the shape of the distribution of total points in Mr. Price's science class? Please help ​

To numerically summarize the center of the distribution of a quantitative variable, we can use the measures of central tendency, which include the mean, median, and mode.

The mean is the sum of all the values divided by the number of values, and it is influenced by extreme values or outliers. The median is the middle value in a set of data when they are arranged in order, and it is not affected by outliers. The mode is the most frequent value in a set of data, and it is not always unique or well-defined. Each measure of central tendency has its advantages and disadvantages and should be chosen based on the characteristics of the data and the research question.

Answer: 8

Step-by-step explanation:

Answer:

y = 4/3x + 4

Step-by-step explanation:

The equation is y = mx + b

m = the slope

b = y-intercept

Slope = rise/run or (y2 - y1) / (x2 - x1)

Points (0,4) and (3,8)

We see the y increase by 4 and the x increase by 3, so the slope is

m = 4/3

Y-intercept is located at (0,4)

So, the equation is y = 4/3x + 4

The slope of the line can be found using the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0, 4) and (x2, y2) = (3, 8)

slope = (8 - 4) / (3 - 0) = 4/3

Now we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is one of the given points. Choosing (0, 4) as the point, we get:

y - 4 = (4/3)(x - 0)

Simplifying:

y - 4 = (4/3)x

y = 4/3 x + 4

Therefore, the equation of the line is y = 4/3 x + 4.

The dimensions of the rectangle, obtained using Pythagorean Theorem are;

The length of the rectangle = 4·√5 units

The width of the rectangle = 2·√5 units

Pythagorean Theorem states that the sum of the squares of the legs of a right triangle is equivalent to the square of the length of the hypotenuse side.

Let x represent the width of the rectangle, we get;

The length = 2·x

Therefore, according to Pythagorean Theorem, we get;

Answer:

The second option is the correct answer.

The equation that represents q being inversely proportional to r is:

q = 4/r

This is because when we say that q is inversely proportional to r, it means that as one variable increases, the other variable decreases in such a way that their product remains constant.

In this case, we can see that if we multiply q and r, we get a constant value of 4.

This is not true for the other equations, so they do not represent q being inversely proportional to r.

Therefore, the equation q = 4/r is the only one in the given options that represents q being inversely proportional to r.

Step-by-step explanation:

The absolute value function f(x) = |x – 2| takes a non-negative value for all real numbers x, and it returns 0 only when x = 2.

The graph of f(x) is symmetric about the vertical line x = 2 and has a vertical asymptote at x = 2.

We have,

The absolute value function f(x) = |x – 2| is a piecewise function that returns the positive distance between the input value x and the number 2.

Geometrically,

It represents the distance of a point on the number line from point 2.

On the coordinate plane,

The graph of the absolute value function is V-shaped, with its vertex at the point (2, 0).

The two arms of the V extend indefinitely in opposite directions, passing through the points (-∞, 2) and (2, +∞) on the positive and negative sides of the x-axis, respectively.

Thus,

The absolute value function f(x) = |x – 2| takes a non-negative value for all real numbers x, and it returns 0 only when x = 2.

If the first and last terms of an arithmetic series are 5 and 27, respectively, and the sum of the series is 192, then the number of terms in the series can be calculated as 12.

To find the number of terms in the arithmetic series, we can use the formula for the sum of an arithmetic series:

Sum = (n/2)(first term + last term)

We are given the first term (5), the last term (27), and the sum (192). Plugging these values into the formula, we have:

192 = (n/2)(5 + 27)

Simplifying the equation:

192 = (n/2)(32)

192 = 16n

Dividing both sides of the equation by 16:

n = 192/16

n = 12

Therefore, the number of terms in the arithmetic series is 12.

The process of differentiation is used to determine the rate at which one quantity changes with respect to another.

If the functional form of a curve is known, differentiation can be used to determine various characteristics of the curve. However, there are some features that cannot be determined through differentiation alone.
Firstly, differentiation can be used to find the slope of the curve at any point. This slope represents the rate at which the dependent variable changes with respect to the independent variable. It can also be used to determine whether the curve is increasing or decreasing at a given point. Additionally, differentiation can be used to find the local maxima and minima of the curve, which correspond to the points where the slope is zero.
However, differentiation cannot be used to determine the concavity of the curve. Concavity refers to the shape of the curve and describes whether the curve is bending upwards or downwards. This characteristic can be determined using the second derivative of the function. If the second derivative is positive, then the curve is concave up, while if it is negative, then the curve is concave down.
Similarly, differentiation cannot be used to determine the location or number of inflection points on the curve. Inflection points are the points on the curve where the concavity changes from concave up to concave down or vice versa. To find the location and number of inflection points, the second derivative must be set equal to zero and solved for the independent variable.
Lastly, differentiation cannot be used to determine the area under the curve between certain bounds. This requires integration, which is the inverse operation of differentiation. Integration can be used to find the area between the curve and the x-axis, and can be approximated using numerical methods.
In summary, differentiation can be used to determine various characteristics of a curve, including its slope and local maxima and minima. However, it cannot be used to determine the concavity, location or number of inflection points, or the area under the curve between certain bounds. These features require additional calculations using the second derivative or integration.

The profit needed is 100000

Profit + commission = Selling price - cost price

Selling Price - 90,000 = 1,00,000 + 10%Selling Price

SP - 90,000 = 1,00,000 + 0.1 * SP

0.9 * SP = 1,00,000 + 90,000

Answer:

a) 35 degrees

b) 170 degrees

Step-by-step explanation:

In A the angles are complementary meaning they add up to 90 degrees. so that means that angle 1 + angle 2 = 90. We know angle 1 is 55 so

55+ angle 2 = 90

subtract 55 on both sides

angle 2 = 35 degrees

B is the same as A but the angles are supplementary so they add up to 180 degrees

10 + angle 2 = 180 degrees

subtract 10 from both sides

angle 2 = 170 degrees

Answer:

If the two angles are complementary and one of them is 55°, then the second one is:

If the two angles are supplementary and one of them is 10°, then the second one is:

To find the probability that 10 customers will arrive in a particular 15-minute period, we can use the Poisson distribution formula:

P(X = k) = (e^(-λ) * λ^k) / k!

Where λ is the mean arrival rate, which is 7 in this case, and k is the number of customers we're interested in, which is 10.

P(X = 10) = (e^(-7) * 7^10) / 10!

Calculating this expression will give us the probability that exactly 10 customers will arrive in a particular 15-minute period.

b. To find the probability that 10 or fewer customers will arrive in a particular 15-minute period, we need to sum up the probabilities of different arrival counts from 0 to 10.

P(X ≤ 10) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 10)

We can use the Poisson distribution formula for each value of k and sum them up to find the cumulative probability.

c. To find the probability of more than 10 customers arriving during a particular 15-minute period, we can calculate the complement of the probability of 10 or fewer customers.

P(X > 10) = 1 - P(X ≤ 10)

This will give us the probability of there being a significant delay at the drive-up window due to more than 10 customers arriving.

The value of the probabilities are

a. P(X < 4) = 0

b. P(X > 3.5) ≈ 0.796875

c. P(4 < X < 5) ≈ 0.5625

d. P(X < 4.5) ≈ 0.703125

e. P(X < 3.5 or X > 4.5) = 0

a. P(X < 4):

To calculate P(X < 4), we need to find the area under the curve of the function f(x) = x/8 for values of x less than 4. However, the given function is only defined for the range 3 < x < 5. Therefore, we cannot directly calculate P(X < 4) using this function. The probability of X being less than 4 is zero since the function does not cover that range.

b. P(X > 3.5):

To calculate P(X > 3.5), we need to find the area under the curve of the function f(x) = x/8 for values of x greater than 3.5. Since the function is defined for 3 < x < 5, we can calculate this probability by integrating the function over the range 3.5 to 5.

Integrating f(x) from 3.5 to 5:

∫[3.5, 5] (x/8) dx = [x²/16] evaluated from 3.5 to 5

= [(5²/16) - (3.5²/16)]

= (25/16) - (12.25/16)

= 12.75/16

= 0.796875

Therefore, P(X > 3.5) ≈ 0.796875.

c. P(4 < X < 5):

To calculate P(4 < X < 5), we need to find the area under the curve of the function f(x) = x/8 for values of x between 4 and 5. We can calculate this probability by integrating the function over the range 4 to 5.

Integrating f(x) from 4 to 5:

∫[4, 5] (x/8) dx = [x²/16] evaluated from 4 to 5

= [(5²/16) - (4²/16)]

= (25/16) - (16/16)

= 9/16

= 0.5625

Therefore, P(4 < X < 5) ≈ 0.5625.

d. P(X < 4.5):

To calculate P(X < 4.5), we need to find the area under the curve of the function f(x) = x/8 for values of x less than 4.5. We can calculate this probability by integrating the function over the range 3 to 4.5.

Integrating f(x) from 3 to 4.5:

∫[3, 4.5] (x/8) dx = [x²/16] evaluated from 3 to 4.5

= [(4.5²/16) - (3²/16)]

= (20.25/16) - (9/16)

= 11.25/16

= 0.703125

Therefore, P(X < 4.5) ≈ 0.703125.

e. P(X < 3.5 or X > 4.5):

To calculate P(X < 3.5 or X > 4.5), we can calculate the sum of probabilities P(X < 3.5) and P(X > 4.5). However, as mentioned earlier, the function f(x) = x/8 is not defined for values less than 3 or greater than 5. Therefore, the probability of X being less than 3.5 or greater than 4.5 is zero.

The probability of rolling an even number on the first roll or rolling a 1 on the second roll is 2/3.

To calculate the probability of rolling an even number on the first roll or rolling a 1 on the second roll of a 6-sided die, we can use the principle of addition.

The probability of rolling an even number on the first roll is 3 out of 6 since there are three even numbers (2, 4, and 6) out of six possible outcomes. Therefore, the probability is 3/6 or 1/2.

The probability of rolling a 1 on the second roll is 1 out of 6 since there is only one outcome that results in rolling a 1.

To calculate the combined probability, we add the individual probabilities:

P(rolling an even number on the first roll) + P(rolling a 1 on the second roll) = 1/2 + 1/6 = 4/6 = 2/3
