Evaluate the sum

\(\bar x_1 = \frac{1590}{20}\)

Evaluate the quotient

\(\bar x_1 = 79.5\)

For period 7, we have:

\(\bar x_7 = \frac{65 * 1 + 75 * 3 + 80 * 5 + 85 * 6 + 90 * 3 + 95 * 2}{1 + 3 + 5 + 6 + 3 + 2}\)

Evaluate the sum

\(\bar x_7 = \frac{1660}{20}\)

Evaluate the quotient

\(\bar x_7 = 83\)

By comparison, 83 is greater than 79.5

The forecast for May using a five-month moving average is 39 (Option E).

Moving average is used for smoothing out time series data to find any trends or cycles within the data. A five-month moving average is the average of the past five months. To calculate the moving average, add up the sales for the previous five months and divide it by five.

According to the question, the sales for the previous five months are: Nov. 39 Dec. 27 Jan. 40 Feb. 42 Mar. 41 April 47

We have to add the sales of these five months, which gives:

27 + 40 + 42 + 41 + 47 = 197

To find the moving average for May, we divide this sum by 5:

197 / 5 = 39.4

Since we have to round the answer to the nearest whole number, we round 39.4 to 39, which is option E.

Step-by-step explanation:

Answer:

The GCF is going to be 9

Step-by-step explanation:

When finding the GCF, you want to do prime factorization of each number.

18's prime factorization is, 2 × 3 × 3, which equals 18

36's prime factorization is 2 × 2 × 3 × 3, which equals 36

45's prime factorization is 5 × 3 × 3, which equals 45

Now all you have to do is find the factors common in each one, which is 2 three's. You then multiply 3 × 3 = 9. That is your answer

The cardinality of the cartesian product of A and B is 18.

Cartesian Product of two sets A and B is defined as the set of all ordered pairs (a,b) where a∈A & b∈B.

Cardinality of a set is defined as the number of elements in that particular set.

For example,  for a set A={2,6,4} , the cardinality is 3.

Given set A= { x | x is a prime number less than 7}

A={2,3,5}

set B =  { y | y is perfect square of an integer and y is less than 29}

B={0,1,4,9,16,25}

The cartesian product of A and B denoted by AxB will be

AxB={(2,0),(2,1),(2,4),(2,9),(2,16),(2,25),(3,0),(3,1),(3,4),(3,9),(3,16),(3,25),(5,0),(5,1),(5,4),(5,9),(5,16),(5,25)}

The number of elements in AxB is 18.

Therefore , the cardinality of the cartesian product of A and B is 18.

The probability least 1 zodiac sign match astrological signs is just the product of (12/12)(11/12 … (8/12).

Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A number between 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty. How likely something is to occur is known as its probability. We can discuss the probabilities of various outcomes—how likely they are—when we aren't sure how a particular event will turn out. Statistics describes the examination of events subject to probability. Probability is a synonym for potential. It is a field of mathematics that examines how random events happen. From zero to one, the value is stated.

The probability that in a group of five friends, at least two share the same astrological sign

= 1 - the probability that all five friends have different astrological signs

= 1 - (12/12)(11/12)(10/12)(9/12)(8/12)

= 1 - 12P5/125

= 1 - 0.381944

Answer:

A, B and D

Step-by-step explanation:

The zeros of f(x) are the points located on the x- axis, that is where y = 0

We can check which ones are the solutions by finding the zeros of f(x)

To find the zeros let f(x) = 0 , that is

(x² + 2x - 8)(x - 6) = 0 ← factorise the quadratic

(x + 4)(x - 2)(x - 6) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 2 = 0 ⇒ x = 2

x - 6 = 0 ⇒ x = 6

There are 3 zeros at x = - 4, x = 2, x = 6

39/52 / 3/4  or  75%

Step-by-step explanation:

There are 4 suits (Clubs, Hearts, Diamonds, and Spades)

There are 13 cards in each suit

52-13=39  

Hope this helps!

To reduce this fraction, divide both the numerator and denominator by their greatest common divisor, which is 13. The reduced fraction is 3/4. So, the probability of not selecting a spade is 3/4.

In a standard deck of 52 cards, there are 13 spades. To find the probability of not selecting a spade, you'll need to determine the number of non-spade cards and divide that by the total number of cards in the deck. There are 52 cards in total, and 13 of them are spades, so there are 52 - 13 = 39 non-spade cards. The probability of selecting a non-spade card is the number of non-spade cards (39) divided by the total number of cards (52). Therefore, the probability is 39/52.

The standard form of the equation of a line perpendicular to the line (3x + 6y = 5) and passing through the point (1, 3) is (2x - y = -1)

To determine the equation of a line perpendicular to the line (3x + 6y = 5) and passing through the point (1, 3), we can follow these steps:

1. Obtain the slope of the provided line.

To do this, we rearrange the equation (3x + 6y = 5) into slope-intercept form (y = mx + b):

6y = -3x + 5

y =\(-\frac{1}{2}x + \frac{5}{6}\)

The slope of the line is the coefficient of x, which is \(\(-\frac{1}{2}\)\).

2. Determine the slope of the line perpendicular to the provided line.

The slope of a line perpendicular to another line is the negative reciprocal of the slope of the provided line.

So, the slope of the perpendicular line is \(\(\frac{2}{1}\)\) or simply 2.

3. Use the slope and the provided point to obtain the equation of the perpendicular line.

We can use the point-slope form of a line to determine the equation:

y - y1 = m(x - x1)

where x1, y1 is the provided point and m is the slope.

Substituting the provided point (1, 3) and the slope 2 into the equation, we have:

y - 3 = 2(x - 1)

4. Convert the equation to standard form.

To convert the equation to standard form, we expand the expression:

y - 3 = 2x - 2

2x - y = -1

Rearranging the equation in the form (Ax + By = C), where A, B, and C are constants, we obtain the standard form:

2x - y = -1

Step-by-step explanation:

the average score was 87%

The volume of a cone using the slicing method is determined by integrating the cross-sectional areas of infinitesimally thin slices along the height of the cone.

To understand the formula for the volume of a cone using the slicing method, we divide the cone into infinitely many thin slices. Each slice can be considered as a circular disc with a certain radius and thickness. By integrating the volumes of all these infinitesimally thin slices along the height of the cone, we obtain the total volume.

The cross-sectional area of each slice is given by the formula for the area of a circle: A = π * r^2, where r is the radius of the slice. The thickness of each slice can be represented as dh, where h is the height of the slice. Thus, the volume of each slice can be expressed as dV = A * dh = π * r^2 * dh.

By integrating the volume of each slice from the base (h = 0) to the top (h = H) of the cone, we get the total volume of the cone: V = ∫[0,H] π * r^2 * dh.

Therefore, the formula for the volume of a cone using the slicing method is V = ∫[0,H] π * r^2 * dh, where r is the radius of the cone and H is the height of the cone. This integration accounts for the variation in the cross-sectional area of the slices as we move along the height of the cone, resulting in an accurate determination of the cone's volume.

In hypothesis testing, a Type I error occurs when we reject a null hypothesis that is actually true. A Type II error occurs when we fail to reject a null hypothesis that is actually false.

In this case, the null hypothesis is that the proportion of people who write with their left hand is equal to 0.33. Let's assume that we have a significance level (α) of 0.05.

A Type I error would occur if we reject the null hypothesis (i.e., we conclude that the proportion of left-handed writers is different from 0.33) when it is actually true. In other words, we would be concluding that there is a difference when there is really no difference. This is sometimes referred to as a "false positive".

A Type II error would occur if we fail to reject the null hypothesis (i.e., we conclude that the proportion of left-handed writers is 0.33) when it is actually false (i.e., the true proportion is not 0.33). In this case, we would be concluding that there is no difference when there is actually a difference. This is sometimes referred to as a "false negative".

So, in summary:

Type I error: Rejecting the null hypothesis when it is actually true (false positive)

Type II error: Failing to reject the null hypothesis when it is actually false (false negative)

Step-by-step explanation:

The ΔH values associated with the dissolution of lithium chloride that are exothermic involve the release of heat energy. When a substance dissolves in a solvent, it can either release heat (exothermic) or absorb heat (endothermic).

Here are the steps to determine if the dissolution of lithium chloride is exothermic:

1. Look for the chemical equation that represents the dissolution of lithium chloride. In this case, it would be:

LiCl(s) → Li+(aq) + Cl-(aq)

2. Examine the enthalpy change (ΔH) associated with this chemical equation. If the ΔH value is negative, it indicates an exothermic process, meaning that heat is released during the dissolution. If the ΔH value is positive, it indicates an endothermic process, meaning that heat is absorbed during the dissolution.

So, to identify the exothermic ΔH values associated with the dissolution of lithium chloride, you need to find experiments or reliable sources that provide the enthalpy change values for this reaction.
