Step-by-step explanation:

Linear regression line y=2.1x+130 predicts sales based on the money spent on advertising.

Linear regression represents the relationship between two variables. the value of y depends on the value of x.

x represents the dollars spent in advertising and y represents the company sales in dollars.

We need to find out sales y when $150 spends on advertising.

Plug in 150 for x and find out y

y = 2.1 x + 130

y = 2.1 (150) + 130

y= 445

The company expects $445 in sales

The company expects $445 in sales.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Linear regression line y = 2.1x + 130 predicts sales based on the money spent on advertising.

Now, Linear regression represents the relationship between two variables. the value of y depends on the value of x.

Here, x represents the dollars spent in advertising and y represents the company sales in dollars.

We need to find out sales y when $150 spends on advertising.

Plug in 150 for x and find out y as;

y = 2.1 x + 130

y = 2.1 (150) + 130

y = 445

Thus, The company expects $445 in sales.

The greatest common factor of 30+42 according to the distributive property is 6×12.

The distributive law, which states that equality is always true in elementary algebra, is generalized by the distributive principle of binary operations in mathematics.

For instance, addition is said to be more evenly distributed than multiplication in elementary mathematics.

So, here we wish to calculate the largest common factor between the numbers 30 and 42, which equals the total of 30 and 42.

Going one for one, the biggest divisor of 30 is 15, and since 42 cannot be divided by 15, this means that there isn't a frequent divisor of 30 and 42.

Since 10 is not a divisor of 42 and is the second largest divisor of 30 (10*3 = 30), it is not a common divisor of both 30 and 42.

6, which is also a divisor of 42 (6*7 = 42), is the third-largest divisor of 30 (6*5 = 30).

Then both 30 and 42 have 6 in common the most.

We may factor the total now by:

30 + 42 = 6*5 + 6*7 = 6*(5 + 7) = 6*12

Therefore, the greatest common factor of 30+42 according to the distributive property is 6×12.

The missing word is "modulus". The statement should read: Twelve is congruent to 60 (modulus 8) because both 12 and 60 have 4 as a remainder when divided by 8.

The modulus function, also known as the modulo operation or mod function, is a mathematical operation that returns the remainder when one integer is divided by another. The modulo operation is a quick and efficient way to find the remainder of a division. For example, if we want to know the remainder when 23 is divided by 5, we can simply compute 23 % 5, which equals 3. The symbol "%" is often used to represent the modulo operation in computer programming, while "mod" is used in mathematical notation to indicate congruence. In either case, the statement means that 12 and 60 leave the same remainder when divided by 8.

Step-by-step explanation:

To provide the most accurate physical description of an irregularly shaped parcel of land, the option that would typically contain enough different measurements is a. metes and bounds.

Metes and bounds is a method of describing land by specifying the distances and directions of its boundary lines. It involves using a combination of compass bearings, distances, and landmarks to define the boundaries of a parcel of land. This approach is particularly useful for irregularly shaped or non-rectangular plots of land, as it allows for more precise and flexible descriptions.

Rectangular survey (also known as the Public Land Survey System or government survey) is primarily used for large-scale surveys and divides land into a grid-like pattern. Subdivision lot and block is a method used in urban areas to describe individual lots within a larger subdivision. While these methods offer their own advantages, they may not provide the same level of accuracy when describing irregularly shaped parcels of land compared to the metes and bounds system.

To find the average cost of producing 400 units of plywood, we need information about the cost function. If we have the cost function per unit, we can calculate the total cost of producing 400 units and then divide it by 400 to find the average cost per unit.

Let's assume the cost function for producing x units of plywood is given by C(x), where C(x) represents the cost in dollars. We can then calculate the total cost of producing 400 units as follows:

Total Cost = C(x) * Number of Units

Total Cost = C(400) * 400

Once we have the total cost, we can find the average cost per unit by dividing the total cost by the number of units:

Average Cost per Unit = Total Cost / Number of Units

Average Cost per Unit = (C(400) * 400) / 400

Average Cost per Unit = C(400)

Therefore, to find the average cost of producing 400 units, we need to know the cost function C(x) specifically for producing 400 units of plywood. Without that information, we cannot provide an exact value for the average cost.

The correct answer is A. Standard deviation measures the dispersion or variability around the expected value or mean of a data set. It is a commonly used statistical measure to quantify the spread of data points.

Standard deviation is calculated by taking the square root of the variance. The variance is the average of the squared differences between each data point and the mean. By squaring the differences, negative values are eliminated, ensuring that the measure of dispersion is always positive.

A higher standard deviation indicates greater variability or dispersion of data points from the mean, while a lower standard deviation suggests that the data points are closer to the mean.

On the other hand, the mean (option B) is a measure of central tendency that represents the average value of a data set. It does not directly measure the dispersion or variability around the mean.

The coefficient of variation (option C) is a relative measure of dispersion that is calculated by dividing the standard deviation by the mean. It is useful for comparing the relative variability between different data sets with different scales or units.

The chi-square test (option D) is a statistical test used to determine if there is a significant association between categorical variables. It is not a measure of dispersion around the expected value.

The length of b and angle B and C are 3cm, 45  degrees and 79 degrees respectively.

To determine the angles and length of sides, we use the sine rule

Given;

a = 2. 5cm

c = 3. 6cm

∠A = 43°

Let's find angle C

\(\frac{sin 43}{2. 5} =\frac{sin C}{3. 6}\)

cross multiply

0. 682 × 3. 6 = sin C × 2. 5

sin C = 2. 4552/ 2. 5

C = \(sin^-^1 ( 0. 982)\)

C = 79°

To find length of b

\(b = \sqrt{c^2 - a^2}\)

substitute the values

b = \(\sqrt{3. 6^2 - 2. 5^2}\)

b = 2. 59 cm

b = 3cm

To find angle B, we have

\(\frac{sin 43}{2. 5} = \frac{sinB}{3}\)

cross multiply

0. 682 × 3= sin B × 2. 5

sin B = 0. 7065

B = \(sin^-^1(0. 7065)\)

B = 45°

Step-by-step explanation:

We can start by assuming that the price of the meal is x dollars. Then, we know that:

15% of x is equal to $4.89

18% of x is equal to $5.87

20% of x is equal to $6.52

We can set up three equations using these statements:

0.15x = 4.89

0.18x = 5.87

0.20x = 6.52

Solving for x in each equation, we get:

x = 4.89 / 0.15 = 32.60

x = 5.87 / 0.18 = 32.61

x = 6.52 / 0.20 = 32.60

Since all three equations give us a value of x that is very close to 32.60, we can assume that the price of the meal was $32.60, rounded to the nearest cent.

y - 1 = (3/5)x

Step-by-step explanation:

First find the slope of this line.  As we move from (0, -2) to (5, 1), x (the 'run') increases by 5 and y (the 'rise') increases by 3.  Thus, the slope of this line is m = rise / run = 3/5.

Using the point-slope formula for the equation of a straight line:

y - 1 = (3/5)(x - 5), or

y - 1 = (3/5)x                This can also be written as 5y - 5 = 3x, or

y = (3/5)x + 1

If the homeowner also had to pay late fees in the amount of $35 four different times, the total cost of the dryer is $809.48. So, correct option is A.

To calculate the total cost of the dryer, we need to add the initial cost of the dryer, the monthly payments, the credit card fees, and the late fees.

The total cost of the dryer can be calculated as follows:

Cost of dryer = $698.27

Total credit card charges = 12 x $1.25 = $15

Total late fees = 4 x $35 = $140

Total cost of the dryer = Cost of dryer + Total credit card charges + Total late fees

= $698.27 + $15 + $140

= $809.27

Therefore, the total cost of the dryer is $809.48, which is the closest option to the calculated answer.

x°=40°, y°=66° and z°=106°.

We have to find unknown values from the given figure.

When any two parallel lines are intersected by another line called a transversal, many pairs of angles are formed.

One of the angles on the parallel line is the corresponding angle.

Corresponding angles: It should be noted that the pair of corresponding angles are equal in measure.

Now, y°=66° (∴ Vertically opposite angles are equal)

and y°= ∠1 (∴ Corresponding angles are equal in measure)

⇒ ∠1=66°

So, 74°+66°+x°=180° (∴ Angles at a point are equal to 180°)

⇒ 140°+x°=180°

⇒ x°=40°

Now, z°=x°+66° (∴ Exterior angle is equal to the sum of the opposite interior angles)

In the given diagram of circle O, we need to find various measurements. Let's consider the following measurements:

Diameter (d): The diameter of a circle is the distance across it, passing through the center. To find the diameter, we can measure the distance between any two points on the circle that pass through the center. Let's say we measure it as 12 units.

Radius (r): The radius of a circle is the distance from the center to any point on the circumference. It is half the length of the diameter. In this case, the radius would be 6 units (12 divided by 2).

Circumference (C): The circumference of a circle is the distance around it. It can be found using the formula C = 2πr, where π is approximately 3.14 and r is the radius. Using the radius of 6 units, we can calculate the circumference as C = 2 * 3.14 * 6 = 37.68 units. Rounding to the nearest whole number, the circumference is approximately 38 units.

Area (A): The area of a circle is the measure of the surface enclosed by it. It can be calculated using the formula A = πr^2. Substituting the radius of 6 units, we can find the area as A = 3.14 * 6^2 = 113.04 square units. Rounding to the nearest whole number, the area is approximately 113 square units.

In summary, for circle O, the diameter is 12 units, the radius is 6 units, the circumference is approximately 38 units, and the area is approximately 113 square units.
