Based on the data provided in the table, an inverse relationship exists between variables x and y. (Option A)

An inverse relationship refers to a relationship between two variables that changes in opposite directions. In other words, an increase in one variable results in a decrease in the other variable and vice versa. An inverse relationship is represented in the form of y = k/x, where x and y are two variables and k is the constant value. Based on the data provided in the table, as the value of x increases, the value of y decreases by a constant value. Hence, the relationship that exists between variable x and y is inverse.

Note: The question is incomplete as it is missing options which are A) inverse B) direct C) independent d) there is no relationship between variable x and y.

Answer:

∠N° = 19°

∠M° = 35°

∠L° = 126°

Step-by-step explanation:

Total angle in a triangle: 180°

∠N° = x°

∠M° = ( 2x - 3 )°

∠L° = ( 7x - 7 )°

180 = N + M + L

180 = x + 2x - 3 + 7x - 7

180 = 10x - 10

10x = 180 + 10

10x = 190

Divide both side by 10

x = 19

∠N° = x° = 19°

∠M° = ( 2x - 3 )° = ( 2(19) - 3 )° = 35°

∠L° = ( 7x - 7 )° = ( 7(19) - 7 )° = 126°

The expressions for the total costs are 2L + 0.7L  and 2.7L

From the question, we have the following parameters that can be used in our computation:

Number of litres = 3

Regular price = L

Discount = 30%

This means that there is a discount on the third item

So, we have the following expression

Total amount = 2 * L + L * (1 - discount)

Substitute the known values in the above equation, so, we have the following representation

Total amount = 2 * L + L * (1 - 30%)

Total amount = 2 * L + L * 0.7

This gives

Total amount = 2L + 0.7L

Evaluate the sum

Total amount = 2.7L

Hence, the expression is 2.7L

The arithmetic mean of a and b in the expression  1/a + 1/b = 1/c is 2c.

Arithmetic mean or average can be obtained by adding all the given values and then dividing the total sum by the number of values.

Given, An expression of the form 1/a + 1/b = 1/c.

We know average of two numbers is sum of those numbers divided by 2.

So,  {(1/a) + (a/b)}/2 = 1/c.

Now to keep the equality we also have to divide the RHS by 2.

Therefore,   {(1/a) + (a/b)}/2 = (1/c)/2.

{(1/a) + (a/b)}/2 = (1/c)×((1/2).

{(1/a) + (a/b)}/2 = 1/2c.

Full Question = The sampling distribution of the sample mean is close to the normal distribution

A. only if the parent population is unimodal, not badly skewed, and does not have outliers.

B. no matter what the distribution of the parent population of what the value of n.

C. if n is large, no matter what the distribution of the parent population.

D. if the standard deviation of the parent population is known.

E. only if both n is large and parent population has a normal distribution.

Answer:

The Empirical Rule, also known as the 68-95-99.7 rule, states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, 95% lies within two standard deviations, and 99.7% lies within three standard deviations.

In this case, the mean is 100 and the standard deviation is 15, so approximately 95% of the data lies within two standard deviations of the mean. Since two standard deviations of 100 is 30 (15 * 2), this means that approximately 95% of the data lies within the range of 70 to 130. Therefore, approximately 5% of the data lies outside of this range, with 2.5% lying below 70 and 2.5% lying above 130.

Therefore, the percent of IQ scores that are above 130 is approximately 2.5%.

Please find attached the presentation of the details of the question as a drawing of the triangles created with MS Word

The parameters of the question are;

The number of arcs on angles b and q = Single arcs

Therefore, based on the arc markings indicating congruency of the angles, we get;

Angle b is congruent to angle q ∠b ≅ ∠q

Therefore, ∠b = ∠q, by the definition of congruency

The number of arcs on angle a and angle s = Double arcs

∠a ≅ ∠s
∠a = ∠s by the definition of congruency

The label on angle ∠a = 45°

The label on angle ∠b = 80°

∠a = ∠s, therefore, ∠s = 45°, by substitution property

∠b = ∠q, therefore, ∠q = 80° by substitution

∠s + ∠q + ∠1 = 180° Angle sum property of a triangle

To find the total time required to produce each product, we can add up the machining, polishing, and assembling hours for each product. For example, for Product I, the total time required would be:

Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours

We can do this for each product to find the total time required for all four products:

Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours

Total time for Product II = 2 hours + 1 hour + 1 hour = 4 hours

Total time for Product III = 2 hours + 2 hours + 2 hours = 6 hours

Total time for Product IV = 4 hours + 3 hours + 1 hour = 8 hours

So, the total time required to produce all four products is 6 hours + 4 hours + 6 hours + 8 hours = 24 hours.

Christopher can work average 9 hours babysitting and 7 hours washing cars in a given week to meet the minimum wage requirement and not exceed the maximum hours he can work.

Christopher is working two summer jobs and has a maximum of 16 hours to work in a given week. He is making $7 per hour babysitting and $10 per hour washing cars. To meet the minimum wage requirement of $130, he needs to make a total of $130 in a week. We can represent this using a system of inequalities. The first inequality is 7xx + 10yy ≥ 130, which means that the total wages (7 times the hours babysitting plus 10 times the hours washing cars) must be greater than or equal to $130. The second inequality is xx + yy ≤ 16, which means that the total hours (babysitting plus washing cars) must be less than or equal to 16. Graphically, we can solve this system of inequalities to find the possible solutions. One possible solution is x = 9 and y = 7, meaning Christopher can work 9 hours babysitting and 7 hours washing cars in a given week to meet the minimum wage requirement and not exceed the maximum hours he can work.

Graphically:

7xx + 10yy ≥ 130

Answer:

In an arithmetic sequence, each term is obtained by adding the common difference to the previous term. In this case, the common difference is 3, so the formula for the nth term of the sequence can be written as:

a^n = a^1 + (n-1) * d

where a^1 is the first term of the sequence, and d is the common difference.

Since the first term of the sequence is -25 and the common difference is 3, we can plug these values into the formula to find the 30th term of the sequence:

a^30 = (-25) + (30-1) * 3

= (-25) + 29 * 3

= (-25) + 87

Ensure that there's an equal number within each quadrant of the town, basically split up the town.  Split towns into regions of populations or population densities and make sure we get the same proportion from each region.  However, we end up splitting the town into different regions. We show the proportion or show who is the most popular candidate in each 1 of the regions, so it could be something like this. That was supposed to be an alternative to a bar graph. The number of results for each different candidate depends on whether or not there's a sort of well-defined districts or areas in the town, but most sorts of relatively large cities have things like that.
