Answer:

C. The data appear to follow a cubic model.

Step-by-step explanation:

Plot the points on the graphing calculator, and then generate the best regression model.

For the linear equation, r = -.0529

For the quadratic equation, R^2 = .8992

For the cubic equation, R^2 = .9678

For the exponential equation, r = -.0814

A cubic regression equation would best fit this data. So the correct answer is C.

Applying the Pythagorean theorem, the length of the unknown side in the right triangle is: a ≈ 13.2.

The Pythagorean theorem is expressed as:

c² = a² + b², given that a and b are small legs of the right triangle and c is the longest leg or hypotenuse facing the right angle in the triangle.

Given the following:

c = 16

b = 9

a = ?

Plug in the values:

16² = a² + 9²

a² = 16² - 9²

a = √(16² - 9²)

a ≈ 13.2

Answer: To solve for x in the equation x/9 = 7/15, we can cross-multiply to get:

15x = 9 * 7

Simplifying the right side, we get:

15x = 63

To solve for x, we can divide both sides by 15:

x = 63/15

Simplifying the fraction on the right side, we get:

x = 4 3/5 or x = 4.2 (rounded to one decimal place)

Therefore, the solution to the equation x/9 = 7/15 is x = 4.2 or x = 4 3/5.

Step-by-step explanation:

to solve such equations u should use (PEMDAS)

parenthesis, exponents, multiplication, division, addition, subtraction

note that multiplication doesn't become always before division if the division is before in the equation we divide then multiply

same with addition and subtraction we add or subtract depnding on what first

other than that we follow the steps i mentioned before

parenthesis, exponents, multiplication, division, addition, subtraction

so solve the parantheses first

then the exponents (you may have not learned this yet)

then multiplication and division together start with the one that comes first

the addition and subtraction start with the one that comes first

so for example :5×5÷5×5

=25÷5×5

=5×5

=25

i started with the first multiplication cuz it came first then division cuz it was before the other multiplication

and then the other multiplication

now here is the answer for your equation 93+48÷(12-42)x17

using PEMDAS(don't write this it's just for explaining)

parantheses first

93+48÷-30×17

we don't have exponents so just skip it

now division and multiplication

93+(-1.6)×17

finally addition amd subtraction

because we don't have subtraction we won't use it too

93 +(-27.2)

=65.8

If John solved the equation x² - 10x + 8 = 0 by completing the square, one of the steps in his process would be: A. (x - 5)² = 17.

In Mathematics, the standard form of a quadratic equation is represented by the following equation;

ax² + bx + c = 0

Next, we would solve the given quadratic equation by using the completing the square method;

x² - 10x + 8 = 0

x² - 10x = -8

In order to complete the square, we would have to add (half the coefficient of the x-term)² to both sides of the quadratic equation as follows:

x² - 10x + (-10/2)² = 8 + (-10/2)²

x² - 10x + 25 = -8 + 25

x² - 10x + 25 = 17

By simplifying, we have;

(x - 5)² = 17

The mean height of sunflowers on Constantin's farm is 210.33 centimetres, rounded to two decimal places.

To find the mean height of sunflowers on Constantin's farm, we need to sum up all the heights and divide by the total number of sunflowers.

Adding up all the heights, we get:

301 + 285 + 20 + 351 + 35 + 205 + 311 + 25 + 45 + 310 + 301 + 305 = 2524

There are 12 sunflowers in total, so we divide the sum by 12:

2524 / 12 = 210.33

Answer:

•  Mean = 30.4

•  Median = 30

•  Mode = None

•  Range = 5

Step-by-step explanation:

To find the mean, we add all the numbers together and divide by the total number of numbers. In this case, we have 5 numbers: 28, 32, 29, 30, and 33. Adding them together gives us 152. Dividing by 5 gives us a mean of 30.4.

To find the median, we need to order the numbers from smallest to largest: 28, 29, 30, 32, and 33. The median is the middle number which is 30.

To find the mode, we look for the number that appears most frequently in the list. In this case, there is no number that appears more than once so there is no mode.

To find the range, we subtract the smallest number from the largest number. In this case, the smallest number is 28 and the largest number is 33 so the range is 5.

Therefore:

•  Mean = 30.4

•  Median = 30

•  Mode = None

•  Range = 5

The surface area of the triangular prism that is shown above is calculated as: 63.25 square yards. .

The surface area of a triangular pyramid is calculated using the formula below:

SA = A + 3a

where we have:

A = the area of the triangular base of the pyramid

a = the area of one of the pyramid's faces.

Area of one of the pyramid's face (a) = 1/2 * base * height = 1/2 * 5 * 7

a = 17.5 square yards

Area of triangular base (A) = 1/2 * base * height = 1/2 * 5 * 4.3

A = 10.75 square yards

Surface area (SA) = 10.75 + 3(17.5) = 63.25 square yards.

The total surface area of the square pyramid is 99 cm²

An equation is an expression that can be used to show the relationship between two or more numbers and variables using mathematical operators.

The area of a figure is the amount of space it occupies in its two dimensional state.

To get the surface area:

Area of base = 10 cm * 2 cm = 20 cm²

Area of first triangle lateral face = (1/2) * 2 cm * 8 cm = 8 cm²

Area of second triangle lateral face = (1/2) * 10 cm * 6.3 cm = 31.5 cm²

Total surface area = 20 cm² + 2(8 cm²) + 2(31.5 cm²) = 99 cm²

Suppose we have a triangle in which:

The lengths and the sine of the angles are related as follows:

[tex]\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}[/tex]

The sum of the measures of the internal angles of a triangle is of 180º, hence the measure of angle B is obtained as follows:

m < B + 81 + 33 = 180

m < B = 180 - 114

m < B = 66º.

Then the relation is:

26/sin(81º) = a/sin(33º) = b/sin(66º).

Then the value of a is obtained as follows:

26/sin(81º) = a/sin(33º)

a = 26 x sine of 33 degrees/sine of 81 degrees

a = 14.3.

The value of b is obtained as follows:

In pigs, the length of pregnancies varies according to a Normal distribution with mean 114 days and standard deviation 5 days, approximately 2.28% of pig pregnancies are longer than 124 days.

We can start by standardizing the value 124 using the formula:

z = (x - μ) / σ

where x is the value we want to standardize, μ is the mean, and σ is the standard deviation.

So in this case:

z = (124 - 114) / 5 = 2

Using a standard normal distribution table or calculator, we can find that the proportion of values greater than 2 is approximately 0.0228.

Therefore, approximately 2.28% of pig pregnancies are longer than 124 days.

As we have proved that PM = PN and Line l is a perpendicular bisector of line segment M N.

A perpendicular bisector is a line that is perpendicular to another line segment and passes through the midpoint of that line segment. In this context, we will prove that if point P is on the perpendicular bisector of line segment MN, then PM = PN.

To prove this, we need to use the properties of perpendicular bisectors. Let l be the perpendicular bisector of line segment MN, passing through its midpoint O. By definition, the line l intersects MN at right angles, and so angle POM and angle PON are both right angles.

Now, since point P lies on the perpendicular bisector l, it is equidistant from the endpoints of the line segment MN, which means that PM = PO and PN = PO. Therefore, PM = PO = PN, and we have proven that if P lies on the perpendicular bisector of MN, then PM = PN.

In summary, we have used the properties of a perpendicular bisector to show that if a point P lies on the perpendicular bisector of line segment MN, then it is equidistant from the endpoints of that segment.
