Answer:

261,7 in^3

Step-by-step explanation:

This time is a bit more difficult because we have to find the base area

Base area = radius^2 x π

in this case we have

5^2π = 25π = 78,5 in^2

now we can use the formula

(78,5 x 10) / 3 = 785/3 = 261,7 in^3

Answer:

\(h=16inches\)

Step-by-step explanation:

From the question we are told that:

Base of  flag \(l_b=8inch\)

Area of flag \(A=64 inch^2\)

Generally the equation for a triangle is mathematically given by

 \(Area=\frac{1}{2}l_b*h\)

Therefore

 \(h=\frac{2A}{l_b}\\h=\frac{2*64}{8}\)

 \(h=16inches\)

Therefore the hieght of the ship is  mathematically given as

 \(h=16inches\)

The approximate population of the town in 2030, using the future value factor, is 304,400.

The future value or the 2030 population of the town in 2030, given its growth rate of 1.06 can be determined by multiplying the future value compounded growth rate (5.743) by the 2000 population of 53,000.

Present population in 2000 = 53,000

Rate of population growth = 1.06 or 6% annually

Period of growth of the population = 30 years (2030 - 2000)

Future value factor of 6% in 30 years = 5.743

Future population of the town = 304,379 (53,000 x 5.743)

304,379 ≈ 304,400 people

Thus, the approximate population of the town in 2030 is 304,400.

(C) Regression analysis is the statistical method commonly used to estimate the level and trend in a time series by modeling the relationship between the data and independent variables.

Regression analysis is the statistical method used to estimate the level and trend in a time series. Time series data represents observations taken at different points in time and is commonly used to analyze trends and patterns over time.

Regression analysis allows us to model the relationship between a dependent variable (in this case, the time series data) and one or more independent variables (such as time or other relevant factors). By using regression analysis, we can identify the underlying trend in the time series and estimate its level.

The regression model captures the relationship between the dependent variable (the time series) and the independent variable(s) by fitting a line or curve that best represents the data. This line or curve helps to identify the overall trend and level of the time series.

While moving average, simulation method, covariance analysis, and correlation analysis are useful techniques in analyzing time series data, they are not specifically designed to estimate the level and trend in a time series. Therefore, (C) regression analysis is the most appropriate method for estimating the level and trend in a time series.

Answer:

P=21

Step-by-step explanation:

The solution to the equation P - 18 = 3 for P is P = 21

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

P - 18 = 3

Add 18 to both sides of the equation

so, we have the following representation

18 + P - 18 = 3 + 18

Evaluate the like terms on the right hand side

This gives

18 + P - 18 = 21

Evaluate the like terms on the left hand side

You will need 6 cups of sugar.

Step - by - Step Explanation

What to find? The number of cups of sugar needed to make a cake with 12 cups of flour.

Given:

Cups of flours = 4

Cups of sugar = 2

Cups of flour =12

Let x be the number of cups of sugar needed to make a cake with 12 cups of flour.

Using proportion;

4 cups of flour = 2 cups of sugar

12 cups of flour = x

Cross - multiply

4x = 24

Divide both-side of the equation by 4

x =6

Hence, you will need 6 cups of sugar.

Answer:

39

Step-by-step explanation:

The "m" in 3(6m-17) is equal to 5, as told by m = 5. When we replace the m with 5, we get the equation

\(3(6*5-17)\)

We get 6 × 5 because when two numbers are next to each other, it means to multiply.

In an equation, always do multiplication first (unless addition/subtraction is in parenthesis). After multiplying, we end up with

\(3(30-17)\)

Always do whatever's in parenthesis first.

\(3(13)\)

Now, we will multiply 3 with 13 because the two numbers are next to each other and there are no more steps to do in parenthesis.

\(3 * 13 = 39\)

The value of the expression 3(6m-17), is 39.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The "m" in 3(6m-17) is equal to 5, as told by m = 5. When we replace the m with 5, we get the equation

E = 3(6m-17)

E = 3 ( 6 x 5 - 17 )

We get 6 × 5 because when two numbers are next to each other, it means to multiply.

In an equation, always do the multiplication first (unless addition/subtraction is in parenthesis). After multiplying, we end up with

E = 3 ( 30 - 17)

Always do whatever's in parenthesis first.

E = 3 ( 13 )

Now, we will multiply 3 by 13 because the two numbers are next to each other and there are no more steps to do in parenthesis.

E = 39

Therefore, the value of the expression 3(6m-17), is 39.

Answer:

The solution of the system of equations is:

x = 3

y = 2

Here we want to solve the system of equations below:

2x + y = 8

x - 3y = -3

First, let's isolate one variable in one of the equations, I will isolate y on the first one.

y = 8 - 2x

Now we can replace that in the other one to get:

x - 3*(8 - 2x) = - 3

x - 24 + 6x = -3

7x = -3 + 24

7x = 21

x = 21/7 = 3

And the value of y is:

y = 8 - 2x = 8 - 2*3 = 2

We can use the following identity:

(Xm, Ym) = X1+X2/2, Y1+Y2/2, where Xm and Ym are the midpoints of X and Y.

So, let's use it.

For question 11, X1 is -3, Y1 is 9, X2 is 3, and Y2 is -7.

Plugging in the points, we get:

-3 + 3 = 0 / 2 = 0 for x, and 9 + (-7) = 2 / 2 = 1 for y. Thus the midpoint is (0,1).

For question 12, X1 is -9, Y1 is -4, X2 is 1, and Y2 is 6. Plugging in the values we get:

-9 + 1 = -8 / 2 = -4 for x, and -4 + 6 = 2 / 2 = 1 for y. So the midpoint is (-4,1)

Answer:

Step-by-step explanation:

#11 (first photo): M = (0, 1)

basically, if you just count the units out (like i went from (-3,9) to (0,9) so i went 3 units to the right) and then do the same for the other point (making sure the number of units is equal so you would want to move 3 left) and then draw a line, you can then connect the other 2 points to create 2 triangles and where they intersect is the midpoint.

so in the picture, the bold green line is the original line, the purple line is the line created when you move units for both points, and the blue lines are the lines created when you fill in the blanks to make the triangles

#12 (picture 2): M = (-4, 1)

and the process is the exact same just change it for the points used

Answer:

P(x < 149.6) = 0.11821

Step-by-step explanation:

We start by calculating the z-score of the parameter given

Mathematically,

z-score = (x-mean)/SD/√n

z-score = (149.6-152.8)/26.2/√94

z-score = -3.2/2.70

z-score = -1.18

So the probability we want to calculate is;

P( x < -1.18)

we can use the standard normal distribution table to get this

From the standard normal distribution table, this value is 0.11821

Step-by-step explanation:

The probability of both rice and carrots being served with dinner is 23.4%.

The probability of Alvin's mother serving rice with dinner can be expressed using the formula P(Rice) = 0.78. This means that the probability of Alvin's mother serving rice with dinner is 78%. The probability of Alvin's mother serving carrots with dinner can be expressed using the formula P(Carrots) = 0.30. This means that the probability of Alvin's mother serving carrots with dinner is 30%. To calculate the combined probability of both rice and carrots being served with dinner, we can use the formula P(Rice and Carrots) = P(Rice) * P(Carrots) = 0.78 * 0.30 = 0.2340. This means that the probability of both rice and carrots being served with dinner is 23.4%.

Answer:

y = m x + b     is the standard form of a straight line

m = (y2 - y1) / (x2 - x1) = (10 - (-8)) / (-3 - 0) = 18 / -3 = -6

When x = 0 y = b from the equation for a line

y = - 8

So our equation is  

y = -6 x - 8

As a check let x = -2 then

y = (-6 * -2) - 8 = 12 - 8 = 4

Check on the graph to verify that this equation holds
