A lumber company is making boards that are 2599.0 millimeters tall. If the boards are too long they must be trimmed, and if the boards are too short they cannot be used. A sample of 23 is made, and it is found that they have a mean of 2600.3 millimeters with a standard deviation of 13.0. A level of significance of 0.05 will be used to determine if the boards are either too long or too short. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the boards are either too long or too short?

Answers

Answer:

There is no sufficient evidence to support  the claim that the boards are either too long or too short

Step-by-step explanation:

From the question we are told that

   The  population mean is [tex]\mu = 2599.0[/tex]

    The sample size is  [tex]n = 23[/tex]

     The  sample mean is  [tex]\= x = 2600.3 \ mm[/tex]

    The  standard deviation is  [tex]\sigma = 13.0[/tex]

     The  level of significance is  [tex]\alpha = 0.05[/tex]

     

The  null hypothesis  is  [tex]H_o : \mu = 2599.0[/tex]

  The  alternative  hypothesis is [tex]H_a : \mu \ne 2599.0[/tex]

Generally the test statistics is mathematically represented as

            [tex]t = \frac{ \= x - \mu }{ \frac{\sigma}{ \sqrt{n} } }[/tex]

=>          [tex]t = \frac{ 2600.3 - 2599.0 }{ \frac{13}{ \sqrt{ 23} } }[/tex]

=>            [tex]t = 0.3689[/tex]

Now from the normal distribution table  the critical value  of  [tex]\alpha[/tex] is  

    [tex]Z_{\alpha } = 1.645[/tex]

Hence from the evaluated and obtained value we see that

    [tex]t < Z_{\alpha }[/tex]

Hence we fail to reject the null hypothesis  

  Thus we can conclude that there is no sufficient evidence to support  the claim that the boards are either too long or too short

Find a 3-by-3 magic square using the numbers 6, 8, 10, 13, 15, 17, 20, 22, and 24.
Fill in the magic square.

Answers

Answer:

Explanation:

I added a picture:

The required magic square using the numbers 6, 8, 10, 13, 15, 17, 20, 22, and 24 is   | 6   |   8    | 10 |

                  | 13  | 15    | 17  |

                  | 20 | 22   | 24 |.

What is a magic square?

A magic square is a square grid of numbers, typically integers, where the numbers in each row, column, and diagonal add up to the same constant value.

Here,
To create a magic square using the numbers 6, 8, 10, 13, 15, 17, 20, 22, and 24, we can follow these steps,

Start by placing the number 15 in the center square of the grid.

Place the number 6 in one corner of the grid. We'll choose the top left corner for this example.

Place the number 24 in the opposite corner. We'll choose the bottom right corner for this example.

Place the remaining numbers in the empty squares of the grid, following these rules:

a. If a square is already occupied, move to the next square in the same direction.

b. If you reach the edge of the grid, wrap around to the other side.

c. If you reach a square that is diagonally adjacent to a previously filled square, move to the next empty square in a clockwise direction.

Using these rules, we can fill in the rest of the grid as follows:

| 6   |   8    | 10 |

| 13  | 15    | 17  |

| 20 | 22   | 24 |

Two angles are supplementary. All we know is that the smaller angle is 126 degrees fewer than the larger one. Find
the measure of the larger angle.

Answers

Answer:

Larger angle= 153°

Smaller angle= 27°

Step-by-step explanation:

Supplementary angles are two angles that add up to 180°

Let the smaller angle= x

Let the larger angle= y

X+y= 180... equation one

Y-126= x..... equation two

(Y-126) +y = 180

2y= 180+126

2y= 306

Y= 153°

Y-126= x.

153-126= x

Find the center of this circle by completing the square. x^2+y^2-6x+8y+10=0
Show work

Answers

Answer:

Center: (3, - 4)

Step-by-step explanation:

We can start to solve this problem by converting this equation into standard form. In other words, by completing the square --- (1)

Subtract " 10 " from either side of the equation x² + y² - 6x + 8y + 10 = 0

x² + y² - 6x + 8y = - 10

Step 1: Complete the square for the expression " x² - 6x "

Using the quadratic equation ax² + bx + c we know that a = 1, b = - 6, c = 0. Assume that d = b / 2a. We have...

d = - 6 / 2(1) = - 6 / 2 = - 3

Now let's assume that e = c - (b²) / 4a...

e = 0 - (-6)² / 4(1) = 0 - 36 / 4 = 0 - 9 = 9 (Substitute values d and e)

(x - 3)² - 9

Step 2: Respectively we can complete the square for the remaining expression " y² + 8y "

Here a = 1, b = 8, c = 0

d = 8 / 2(1) = 8 / 2 = 4

e = 0 - (8)² / 4(1) = 0 - 64 / 4 = 0 - 16 = - 16 (Substitute values)

(y + 4)² - 16

This leaves us with the expression " (x - 3)² - 9 + (y + 4)² - 16 = - 10. " If we simplify this a bit further it leaves us with the following circle equation. Using this we can identify the center of the circle as well --- (2)

[tex]\mathrm{Standard}\:\mathrm{Circle}\:\mathrm{Equation} : (x - 3)^2 + (y +4)^2 = 15,\\\mathrm{General}\:\mathrm{Form} : (x - h)^2 + (y +k)^2 = r^2,\\\mathrm{Properties} : \mathrm{Center} = (3, - 4), \mathrm{Radius} = \sqrt{15}[/tex]

As you can see our center here is (3, - 4)

Jessica takes 4 business trips a month for x months in a row. Write an expression to show how many business trips Jessica has taken.

Answers

Answer:

[tex] t = 4x [/tex]

Step-by-step explanation:

We are given that in 1 month, Jessica takes 4 business trips. Take 4 as our coefficient or constant.

Let t be the total number of business trips Jessica has taken.

For 1 month, 4 trips are taken.

For x months, total business trips taken will be expressed as,

[tex] t = 4x [/tex]

Let's say for example, we have 5 months in a row, i.e. x = 5. Total business trips taken by Jessica can be gotten by simply plugging in the value of x.

[tex] t = 4(5) = 20 trips [/tex]

In 5 months in a row, Jessica takes 20 business trips.

Annie is running a trail that is 4 1/2 miles long. She ran the first 2/3 of the distance. Then the trail became very steep, so she slowed down to a walk. Annie walked for 1/2 of the remaining distance and then ran again for the rest of the way. How far did Annie walk? Write the answer as a simplified fraction.

Answers

Answer:

Annie walked 1 11/12 miles

Step-by-step explanation:

Trail= 4 1/2 miles

Annie ran the first 2/3 miles

Remaining miles= Total miles - Miles covered first

= 4 1/2 - 2/3

= 9/2 - 2/3

= 27-4 / 6

= 23/6 miles

Remaining miles = 23/6 miles

Annie walked for 1/2 of the remaining distance

1/2 of the remaining miles= 1/2 × 23/6

=23 / 12

= 1 11/12

Annie walked 1 11/12 miles

Evaluate the expression when a = -6 and y=2 . a-6y​

Answers

Answer:

-18

Step-by-step explanation:

So we have the expression:

[tex]a-6y[/tex]

And we want to evaluate it when y=2 and a=-6.

Substitute in these values:

[tex]=(-6)-6(2)[/tex]

Multiply:

[tex]=(-6)-12[/tex]

Subtract:

[tex]=-18[/tex]

Answer:

-18

Step-by-step explanation:

We are given the expression:

[tex]a-6y[/tex]

and asked to evaluate when a= -6 and y=2.

Therefore, we must substitute -6 in for a and 2 in for y.

[tex]a-6y , a=-6, y=2[/tex]

[tex](-6)-6(2)[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition, and Subtraction.

Multiply 6 and 2.

[tex](-6)-(6*2)[/tex]

[tex](-6)-(12)[/tex]

[tex](-6)-12[/tex]

Subtract 12 from -6.

[tex](-6-12)[/tex]

[tex]-18[/tex]

The expression a-6y when evaluated for a=-6 and y=2 is equal to -18.

Let un be the nth Fibonacci number. Prove that the Euclidean algorithm takes precisely n steps to prove that gcd(un+1, un) = 1.

Answers

Hello, Please consider the following.

Fibonacci numbers are defined as

[tex]u_0=1\\\\u_1=1\\\\u_{n+2}=u_{n+1}+u_{n} \ for \ n\geq 0[/tex]

Step 1 - The proposition is true for n = 1

[tex]GCD(u_2,u_1) ?\\[/tex]

Let's apply Euclidean algorithm

[tex]u_1=1, u_2=2\\\\u_2=2\times u_1+0 = 2 \times 1 +0[/tex]

This is exactly 1 step and [tex]GCD(u_2,u_1) =1[/tex]

Step 2 - We assume that this is true for k, meaning that the Euclidean algorithm takes precisely k steps to prove that [tex]GCD(u_{k+1},u_{k})=1[/tex]

[tex]u_{k+2}=u_{k+1}+u_k \ and \ 0 < u_k < u_{k+1}[/tex]

So, the first step of the algorithm is

[tex]u_{k+2}=u_{k+1}\times 1 +u_{k}[/tex]

And from now, we need to find [tex]GCD(u_{k+1},u_k)[/tex] which is 1 and takes k steps, by induction Hypothesis. Therefore, it takes k + 1 steps to find [tex]GCD(u_{k+2},u_{k+1})=1[/tex]

Step 3 - Conclusion

We have just proved that the Euclidean algorithm takes precisely n steps to prove that [tex]GCD(u_{n+1},u_{n})=1[/tex]

Evaluate: [(- 16) + 4] ÷ [(-2) + 5]

Answers

Answer:

We need to evaluate this: [(-16)+4] / [(-2)+5]

First, we do the brackets:

[(-16)+4][(-2)+5]

[(-16)+4] = -16 + 4 = -12

[(-2) + 5] = -2 + 5 = 3

Now, we only need to divide, as we have calculated both brackets:

-12/3 = -4

(Remember that when dividing a negative number by a positive one, we always obtain a negative)

So the result is -4

Our focus here will be on the figures inside () to start on with; considering these figures are - & + accordingly:-

( (-16) + 4 ) ÷ ( (-2) + 5 )
= (-16 + 4) ÷ (-2 + 5)
= (-12) ÷ (+3)
= -4

So, the answer is (-4)
