The formula for calculating a histogram is (Number of Data Points in Bin) / (Total Number of Data Points).

A histogram is a graphical representation of data which displays how often certain values occur within a set of data. It is a type of bar graph that displays the number of values within each bin or interval. The bins are usually of equal size, and the height of each bar indicates the frequency of the values within the bin. Histograms are used to display the distribution of data, allowing a quick visual representation of the data.= (Number of Data Points in Bin) / (Total Number of Data Points)

suppose we have a set of data with the following values: 4, 5, 6, 7, 8, 9, 10, 11, 12. To construct a histogram, we would first divide the data into bins of equal size. In this case, we could use bins of size 2, so the bins would be 4-5, 6-7, 8-9, and 10-11. We would then count the number of data points in each bin, resulting in the following: 4-5: 2 data points; 6-7: 2 data points; 8-9: 2 data points; 10-11: 2 data points. To calculate the histogram we would take the number of data points in each bin, and divide it by the total number of data points (8). This would give us the following histogram: 4-5: 2/8; 6-7: 2/8; 8-9: 2/8; 10-11: 2/8.

In summary, a histogram is a graphical representation of data which displays how often certain values occur within a set of data. It is constructed by dividing the data into bins of equal size, and the height of each bar indicates the frequency of the values within the bin. The formula for calculating a histogram is (Number of Data Points in Bin) / (Total Number of Data Points).

It will take the town 21 years 4 months to reach 4600 in population

a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

initial population = 3000

population increase every year = 2.5% of 3000

which is 2.5/100 x 3000 = 75

let the time taken to reach 4600 be d

increment for d number of years = 75d

Total population after d years is 75d + 3000

so 75d + 3000 = 4600

75d = 4600  - 3000

75d = 1600

d = 1600/75

d = 21.33 years which is 21 years 4 months

LCL for the p-control chart: 0.033

UCL for the p-control chart: 0.287

To calculate the Lower Control Limit (LCL) and Upper Control Limit (UCL) for the p control chart, we need to use the formulas:

LCL = p - 3√(p(1-p)/n)

UCL = p + 3√(p(1-p)/n)

Where p is the overall proportion of defective items, and n is the number of observations in each sample.

First, let's calculate p:

Total defective items = 2 + 5 + 3 + 4 + 1 + 2 + 3 + 6 + 2 + 4 = 32

Total observations = 10 * 20 = 200

p = Total defective items / Total observations = 32 / 200 = 0.16

Next, let's calculate the LCL and UCL:

LCL = 0.16 - 3√(0.16(1-0.16)/20)

UCL = 0.16 + 3√(0.16(1-0.16)/20)

Now we can calculate the values:

LCL = 0.16 - 3√(0.160.84/20) = 0.16 - 0.127 = 0.033

UCL = 0.16 + 3√(0.160.84/20) = 0.16 + 0.127 = 0.287

The LCL for the p-control chart is 0.033 and the UCL is 0.287.

To draw the p chart, you can use the number of defective items (red chocolates) in each sample (s1 to s10) divided by the total observations in each sample (20). Plot these proportions on the y-axis and the sample number (s1 to s10) on the x-axis.

To determine if there are any points out of control, you need to check if any data points fall outside the calculated control limits (LCL and UCL). If any point falls outside these limits, it indicates a potential out-of-control situation.

Step-by-step explanation:

The derivative of F(x) is \(F'(x) = x^{(1/3)\).

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

To find the derivative of the given function F(x), we will apply the fundamental theorem of calculus and differentiate the integral with respect to x.

Let's compute F'(x):

F(x) = ∫[0 to x] \(t^{(1/3)} dt\)

To differentiate the integral with respect to x, we'll use the Leibniz integral rule:

F'(x) = d/dx ∫[0 to x] \(t^{(1/3)} dt\)

According to the Leibniz integral rule, we have to apply the chain rule to the upper limit of the integral.

\(F'(x) = x^{(1/3)} d(x)/dx - 0^{(1/3)} d(0)/dx\)   [applying the chain rule to the upper limit]

Since the upper limit of the integral is x, the derivative of x with respect to x is 1, and the derivative of 0 with respect to x is 0.

\(F'(x) = x^{(1/3)} (1) - 0^{(1/3)} (0)\)

\(F'(x) = x^{(1/3)\)

Therefore, the derivative of F(x) is \(F'(x) = x^{(1/3)\).

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (2, - 2) ← 2 points on the line

m = \(\frac{-2-4}{2-(-2)}\) = \(\frac{-6}{2+2}\) = \(\frac{-6}{4}\) = - \(\frac{3}{2}\)

The -value of the test is 1.90. This indicates that the mean processing time is significantly greater than 5.5 hours, supporting the manufacturer's desire to set a standard time required by employees to complete a certain process

The t-value will be equal to 1.39 for the given statistics.

To test if the mean processing time exceeds 5.5 hours, we can use a one-sample t-test.

The null hypothesis is that the mean processing time is less than or equal to 5.5 hours:

H0: µ ≤ 5.5

The alternative hypothesis is that the mean processing time is greater than 5.5 hours:

Ha: µ > 5.5

We will use a significance level of 0.05.

The formula for the t-test statistic is:

t = (X - µ) / (s / √n)

Where:

X = sample mean

µ = hypothesized population mean

s = sample standard deviation

n = sample size

Substituting the given values, we get:

t = (6 - 5.5) / (2 / √21) = 1.386

The degree of freedom for the t-test is n-1 = 20.

Using a t-table or calculator, the p-value associated with a t-value of 1.386 and 20 degrees of freedom is 0.093.

Since the p-value (0.093) is greater than the significance level (0.05), we fail to reject the null hypothesis. Therefore, there is not enough evidence to suggest that the mean processing time exceeds 5.5 hours.

  The slope of the curve \(y = x^2 - 2x - 5\) at the point P(2, -5) can be found by evaluating the limit of the secant slope as the second point on the secant line approaches the point P.the slope of the curve at point P(2, -5) is 2.

To find the slope, we consider a point Q(x, y) on the curve that is close to P(2, -5). The secant line passing through P and Q can be represented by the equation:
m = (y - (-5))/(x - 2)
We can rewrite this equation as:
m = (y + 5)/(x - 2)
To find the slope at point P, we need to find the limit of m as Q approaches P. This can be done by evaluating the limit of m as x approaches 2:
\(lim(x- > 2) (y + 5)/(x - 2)\)
By substituting the coordinates of point P into the equation, we have:
lim(x->2) \((x^2 - 2x - 5 + 5)/(x - 2)\)
Simplifying the expression, we get:
lim(x->2) \((x^2 - 2x)/(x - 2)\)
Factoring out an x from the numerator, we have:
lim(x->2) x(x - 2)/(x - 2)
Canceling out the common factor of (x - 2), we are left with:
lim(x->2) x
Evaluating the limit, we find:
lim(x->2) x = 2
Therefore, the slope of the curve at point P(2, -5) is 2.

hf(x+h) - f(x) = 2hx^2 + 4hx^2 + 2h^3 - 7hx - 7h^2 + 9h - 2x^2 + 7x - 9.

f(x+h) = 2(x+h)^2 - 7(x+h) + 9

Simplifying this expression, we get:

f(x+h) = 2(x^2 + 2xh + h^2) - 7x - 7h + 9

= 2x^2 + 4xh + 2h^2 - 7x - 7h + 9

So, f(x+h) = 2x^2 + 4xh + 2h^2 - 7x - 7h + 9.

f(x+h) - f(x), we subtract the value of f(x) from f(x+h):

f(x+h) - f(x) = (2x^2 + 4xh + 2h^2 - 7x - 7h + 9) - (2x^2 - 7x + 9)

f(x+h) - f(x) = 2x^2 + 4xh + 2h^2 - 7x - 7h + 9 - 2x^2 + 7x - 9

= 4xh + 2h^2 - 7h

So, f(x+h) - f(x) = 4xh + 2h^2 - 7h.

hf(x+h) - f(x), we multiply f(x+h) by h and subtract f(x) from the result:

hf(x+h) - f(x) = h(2x^2 + 4xh + 2h^2 - 7x - 7h + 9) - (2x^2 - 7x + 9)

Expanding and simplifying this expression, we get:

hf(x+h) - f(x) = 2hx^2 + 4hx^2 + 2h^3 - 7hx - 7h^2 + 9h - 2x^2 + 7x - 9

So, hf(x+h) - f(x) = 2hx^2 + 4hx^2 + 2h^3 - 7hx - 7h^2 + 9h - 2x^2 + 7x - 9.

In exploratory data analysis, the first step is to identify the research question and the two variables of interest. The predictor variable (also known as the explanatory variable or independent variable) is the one that is used to explain or predict the outcome of the response variable (also known as the dependent variable).

After identifying the two variables, one can use software such as Minitab to create a scatterplot of the data. The scatterplot helps to visualize the relationship between the two variables.

To characterize the association between the two variables, we would first determine if the relationship appears to be linear or nonlinear. If the relationship is roughly linear, we would then determine if it is negative (meaning that as one variable increases, the other tends to decrease), positive (meaning that as one variable increases, the other tends to increase), or none (meaning that there is no clear trend).

The correct option is Option D: the value of g(1) is 4.

An inverse function is a function which reverses the function direction for which the range of the function becomes the domain and the domain of the function becomes the range of the inverse function.

If y =  f(x) is the given function then x = f⁻¹(y) is the inverse function.

Here, given in the question the value of x and the value of f(x).

for which f(-1)= -3

f(1)= -1

f(4)= 1

f(6)= 4

f(7)= 6

So let the value of f(x) is y

we can write y=f(x)

applying inverse on both side

⇒f⁻¹(y)= f⁻¹(f(x))

⇒f⁻¹(y)= x

⇒ x= f⁻¹(y)

given that the inverse of f(x) is g(x)

so now the equation will be

⇒ x= f⁻¹(y)=g)y)

⇒ x= g(y)

according to the above function at the value of y, the inverse of the function will be g(y)=  f⁻¹(y)

so from the table it is clear that at the value of x=4, f(x)=y=1.

So at y=1, 1=f(4)

so applying inverse on both side

⇒ f⁻¹(1)= f⁻¹(f(4))

⇒ f⁻¹(1)= 4

⇒g(1)= 4

Therefore the value of the g(1)= 4.
