Part 1 pls help with this​

The test hypothesis using 0.05 significance level has the following results:

Part 1:

State the null and alternative hypotheses for treatments:

Null hypothesis=treatment means do not differ

Alternative hypothesis=The means are different

State the decision rule for treatments:

Table value of F(1,2)=18.51

If the calculated F>18.51, reject the null hypothesis

Decision: Treatments

Calculated F=43.75 >18.51, here, we reject the null hypothesis

Hence, we conclude that the treatment means differ.

Part 2:

State the null and alternate hypotheses for blocks.

Null hypothesis=block means do not differ

Alternative hypothesis: At least on pair of means are different

Also, state the decision rule for blocks:

Table value of F(2,2)=19.0

If the calculated F >19.0, reject the null hypothesis

Decision: Blocks

Calculated F=8.14 < 19.0, we do not reject the null hypothesis

Hence, we conclude that the block means do not differ.

The quotient when 0.03 is divided by 0.148 after rounding it off is 0.2.

According to the question,

We have the following information:

0.03 is divided by 0.148

And it can be simply expressed as 0.03/0.148

Now, we have the quotient as:

0.2027

Now, when rounding off the numbers we know that the digits from where we are rounding off we look at the right next to that digit and when that digit is greater than 5 then the digit should be increased by 1 and when that digit is less than 5 then the digit should be the same.

So, we will round it off by taking the underlined digit to be next to first 2:

So, the digit is 0.

Butt if we are taking the underlined digit as 2 to be the next 2 then the digit next to it is 7 which is greater than 5.

Then, we have:

0.2

Hence, the quotient when 0.03 is divided by 0.148 after rounding it off is 0.2.

a) As per the given percentage, the number of registered voters in the town who cast the votes are 155,952.

b) Reese claim is incorrect. The number he mentioned as registered voters is greater than the actual number of registered voters..

Percentage:

A percentage is a number or ratio which can be expressed as a fraction of 100.

For example, 57% can be written as 57/100.

Given,

The register voters and other in the town cast their vote on the election day.

a. In that particular town, 273,600 votes were cast in an election. And there are 57% of those who were registered voted.

Here we need to find how many registered voters are there in the town.

b. Reese claims that there are 60% of the registered voters cast 273,600 votes, there would be fewer registered voters than above.

Now we have also need to find whether his statement is correct or not with the reason.

Let x be the total number of registered voter who cast the vote.

From the given details, we know that, there are 273,600 voters are cast.

And 57% of them are registered voters.

So, it can be calculated as follows,

=> x  = 273600 of 57%

=> x = 273600 x 57%

=> x = 273600 x 57/100

=> x = 2736 x 57

=> x = 155, 952

Therefore, there are 155,952 registered voter in the town who cast the vote.

Based on these calculation we know that, Reese claims is incorrect because there the number of registered voters is 155, 952 which is not equal to the number he mentioned.

with the ticket price at $11 the average attendance has been 28000. when the price dropped to $10, the average attendance rose to 34000. Then the equation is y= -6000x+94000

We need to write expression of the attendance in terms of the price of the tickets.  We can determine the percentage increase of the attendance by decreasing the tickets price. We can have two points:

(11,28000) and (10,34000)

We have calculate the slope:

m= ( 34000 - 28000)/ (10-11)

m= - 6000

Substitute point into:

y= mx  +c

28000= -6000*11+c

28000+66000=c

94000=c

The equation is:

y= -6000x+94000

The gcf of 15 and 36 is 3 and   15 + 36 by distributive property is 51.

What is gcf?

The gcf(greatest common factor) is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

What is distributive property?

According to the distributive property, multiplying the sum of two or more addends by a number produces the same result as when each addend is multiplied individually by the number and the products are added together.                         A (B + C) = AB + AC.

Given that, 15 and 36

Factor of 15 = 3 × 5

Factor of 36 = 2 × 2 × 3 × 3

gcf of 15 and 35 is 3 because 3 only one 3 is common in both the number.

Applying distributive property on 15 an 35 = 15 + 36

                                                                      = 3×5 + 3×12

                                                                      = 3(5 + 12)

                                                                      = 3(17) = 51

Therefore, the gcf of 15 and 36 is 3 and   15 + 36 by distributive property is 51.

Ignore the angles of triangle DEF. They complicate things when they don't need to be like that.

The distance from E to F is 3 units since there are 3 spaces between the points. Or you could subtract the x coordinates of each point, so 7-4 = 3.

So far we have one pair of congruent sides

EF = BC = 3

----------------------

Let's use the distance formula to find the distance from D to E

[tex]D = (x_1,y_1) = (3,-1) \text{ and } E = (x_2, y_2) = (7,-4)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-7)^2 + (-1-(-4))^2}\\\\d = \sqrt{(3-7)^2 + (-1+4)^2}\\\\d = \sqrt{(-4)^2 + (3)^2}\\\\d = \sqrt{16 + 9}\\\\d = \sqrt{25}\\\\d = 5\\\\[/tex]

Segment DE is exactly 5 units long.

We have another pair of congruent sides between the two triangles

AB = DE = 5

----------------------

We'll use the distance formula one last time to find the length of side FD.

[tex]D = (x_1,y_1) = (3,-1) \text{ and } F = (x_2, y_2) = (4,-4)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-4)^2 + (-1-(-4))^2}\\\\d = \sqrt{(3-4)^2 + (-1+4)^2}\\\\d = \sqrt{(-1)^2 + (3)^2}\\\\d = \sqrt{1 + 9}\\\\d = \sqrt{10}\\\\\sqrt{10} \approx 3.162278 \approx 3.2\\\\[/tex]

Side FD is approximately 3.2 units long, which matches with AC = 3.2

--------------------

Here are the three paired sides that are congruent to one another

Since we have three pairs of congruent sides, we can use the SSS (side side side) congruence theorem to prove the triangles are congruent.

Congruent triangles are identical copies or clones of one another. One triangle is just a reflected and translated version of the other.

This means they have the same corresponding angle measures, and the same corresponding side lengths.

If a car with an initial speed of 36 km/h accelerates at a uniform rate of 2.4 m/s^2 for 2.5 seconds. The final speed is 16m/s and displacement of the car during this time is 32.5m.

23.7 km/h = 10 m/s

Using this formula to find the speed  vf = vi + a(Dt) for the final speed

Where:

Initial speed = 10 m/s

Acceleration = 2.4 m/s2

Time = 2.5 s

Let plug in the formula

vf = (10 m/s) + (2.4 m/s2)(2.5 s)

vf = 16m/s  fast car

Now, let's find or determine  the displacement

Using this  formula  Dx = vi(Dt) + 1/2a(Dt)2

Let plug in the formula

Dx = (10 m/s)(2.5 s) + 1/2(2.4 m/s2)(2.5 s)²

Dx = 32.5 m

Therefore we can conclude that the speed is 16m/s and the displacement is  32.5 m.

When working with unknowable numbers, we can simplify equations by using the distributive property. If the equation be 10x² - (9x + 4x²) + 7 + (5x - 8) then we get 6x² - 4x - 1.

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

Let the equation be 10x² - (9x + 4x²) + 7 + (5x - 8)

Apply rule: a +(b + c) = a + b + c

7 + (5x - 8) = 7 + 5x - 8

= 10 x²- (9 x + 4 x²) + 7 + 5x - 8

simplifying the above equation, we get

= -(9x + 4x²) + 10x² + 5x + 7 - 8

Subtract the numbers: 7 - 8 = -1

= -(9x + 4x²) + 10x² + 5x - 1

Apply the distributive law: -(a + b) = -a - b = 0

-(9x + 4x²) = - 9x - 4x²

= -9x - 4x² + 10x² + 5x - 1

Add similar elements:

-4x² + 10x² = 6x² = -9x + 6x² + 5x - 1

simplifying the above equation, we get

= 6x² - 9x + 5x - 1

Add similar elements: -9x + 5x = -4x

= 6x² - 4x - 1

Therefore, by simplifying the equation, we get 6x² - 4x - 1.
