Logarithm helps to find how much a number must be raised. The value of x in the function logₓ729=3 is 9.

A log function is a way to find how much a number must be raised in order to get the desired number.

\(a^c =b\)

can be written as

\(\rm{log_ab=c\)

where a is the base to which the power is to be raised,

b is the desired number that we want when power is to be raised,

c is the power that must be raised to a to get b.

We know the basics of logarithms, therefore, we can write,

\(\rm log_x 729 = 3\\\\x^3 = 729\\\\x = 9\)

Hence, the value of x in the function logₓ729=3 is 9.

The probability that John is late for work is 0.26, or 26%.

To calculate the probability that John is late for work, we need to use the law of total probability, which states that the probability of an event can be found by considering all possible ways that the event can occur.

Let B be the event that John takes the bus, and S be the event that he takes the subway. Let L be the event that he is late for work.

We know that P(B) = 0.3, P(S) = 0.7, P(L|B) = 0.4, and P(L|S) = 0.2. We want to find P(L), the probability that John is late for work.

Using the law of total probability, we have:

P(L) = P(L|B)P(B) + P(L|S)P(S)

= 0.4 x 0.3 + 0.2 x 0.7

= 0.12 + 0.14

= 0.26

Therefore, the probability that John is late for work is 0.26, or 26%.

An example of a statistical measure is the quartile, which splits a set of data into four equally sized sections. When describing the distribution of data and identifying the range of values that the majority of the data falls within, quartiles are utilised.

First, let's order the given numbers in ascending order from least to greatest: 18, 25, 25, 28, 44, 46, 47, 76, 83.

Now, to find the third quartile (Q3), we need to determine the median of the upper half of the data. Since there are 9 data points, the middle number is the 5th data point, which is 44. The upper half consists of the numbers 46, 47, 76, and 83.

The third quartile (Q3) is the median of the upper half. Since there are 4 data points in the upper half, the median is the average of the 2 middle numbers (46 and 47).

Therefore, Q3 = (46 + 47) / 2 = 46.5.

Next, we need to find the first quartile (Q1), which is the median of the lower half of the data. The lower half consists of the numbers 18, 25, 25, and 28. The median of these numbers is the average of the 2 middle numbers (25 and 25). Therefore, Q1 = (25 + 25) / 2 = 25.

Finally, to find the interquartile range (IQR), we subtract Q1 from Q3: IQR = Q3 - Q1 = 46.5 - 25 = 21.5.

The final answer is that the probability of rolling a six sided die six times and having all numbers from 1 through 6 appear once in any order is 1.54.

This is calculated by probability of independent events.

We know that any die can get any of the six sides and all the throws are independent, so their intersection is given by the product.

So, P(A and B occurring together )= P(A)P(B) if A and B are independent.

And the probability of the throws i.e. the no. of ways every throw gets a unique number is (6/6) x (5/6) x (4/6) x (3/6) x (2/6) x (1/6)

This is because, being the probability of independent events , they are multiplied.

so, the total probability is 6.5.4.3.2.1/6^6 = 1.54

a) An example of a polynomial of degree 5 for which x=1 is a critical number but not a local minimum nor a local maximum is:

P(x) = (x-1)^2(x-2)(x+1)(x+3)

To see why x=1 is a critical point but not a local minimum nor a local maximum, we can compute the first and second derivatives of P(x):

P'(x) = 2(x-1)(x-2)(x+1)(x+3) + (x-1)^2(x+1)(x+3) + (x-1)^2(x-2)(x+3) + (x-1)^2(x-2)(x+1)

P''(x) = 2(x-2)(x+1)(x+3) + 2(x-1)(x+1)(x+3) + 2(x-1)(x-2)(x+3) + 2(x-1)(x-2)(x+1) + 4(x-1)(x-2)(x+1)(x+3)

We can see that P'(1) = 0, so x=1 is a critical point. To determine whether it's a local minimum or maximum, we need to look at the sign of P''(1). However, computing P''(1) gives us:

P''(1) = 2(1-2)(1+1)(1+3) + 2(1-1)(1+1)(1+3) + 2(1-1)(1-2)(1+3) + 2(1-1)(1-2)(1+1) + 4(1-1)(1-2)(1+1)(1+3) = 16

Since P''(1) is positive, we know that x=1 is not a local maximum or a local minimum, but rather an inflection point.

b) To determine the intervals on which f(x) = (x-2)(x+3) is decreasing and increasing and find local minima and maxima, we can compute the first and second derivatives of f(x):

f'(x) = 2x+1

f''(x) = 2

We can see that f''(x) is always positive, so f(x) is always concave up. Therefore, any critical points of f(x) will be local minima. To find the critical points, we set f'(x) = 0:

2x+1 = 0

x = -1/2

So x=-1/2 is the only critical point of f(x). To determine whether it's a local minimum or not, we can look at the sign of f'(x) on either side of x=-1/2:

When x < -1/2: f'(x) < 0, so f(x) is decreasing.

When x > -1/2: f'(x) > 0, so f(x) is increasing.

Therefore, we know that x=-1/2 is a local minimum of f(x).

c) To determine the intervals on which f(x) = (x+1)(x-2)(x+3) is decreasing and increasing and find local minima and maxima, we can compute the first and second derivatives of f(x):

f'(x) = 3x^2-2x-7

f''(x) = 6x-2

To find the critical points of f(x), we set f'(x) = 0:

Answer:

Chord

Step-by-step explanation:

Notice that the highlighted part is the line segment that joins the points J and E on the circle, which is known as a chord.

Answer: To find the equation of a line passing through two points, we can use the point-slope form of the equation:

y - y1 = m(x - x1)

where (x1, y1) are the coordinates of one of the points, and m is the slope of the line.

To find the slope, we can use the formula:

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

where (x1, y1) and (x2, y2) are the coordinates of the two points.

So, let's plug in the values we have:

m = (-8 - 3)/(-8 - (-10)) = (-8 - 3)/2 = -11/2

Now we can use either point to find the equation. Let's use (-10, 3):

y - 3 = (-11/2)(x - (-10))

y - 3 = (-11/2)x - 55/2

y = (-11/2)x - 49/2

So the equation of the line through (-10, 3) and (-8, -8) is:

y = (-11/2)x - 49/2.

The ordered pair (2, 7) is a solution to the equation  9 x-y-11=0.

To determine whether the ordered pair (2, 7) is a solution of the equation 9x - y - 11 = 0.

we substitute the values of x and y from the ordered pair into the equation and check if it satisfies the equation.

Given ordered pair: (2, 7)

Substituting x = 2 and y = 7 into the equation:

9(2) - 7 - 11

= 18 - 7 - 11

= 18 - 18

= 0

Since the equation holds true when the values of x and y are substituted, the ordered pair (2, 7) is a solution of the equation 9x - y - 11 = 0.
