Gary’s family has 20 slices of pizza for dinner. His sister took 1/10 of the slices, his brother ate 25% of the slices, and his parents ate 2/5 of the pieces. How many pieces were left for Gary to eat

Answers

Answer 1
Okay so
1/10 of 20 is 2.
25% of 20 is 5.
2/5 of 20 is 8.
Add these together: 15
20-15=5.
This means there are 5 slices left for Gary.

Hope this is helpful!!

Step 1: Write equation

3(a + 3) + 6 = 30

Step 2: Solve for a

Distribute 3:                                  3a + 9 + 6 = 30Combine like terms:                     3a + 15 = 30Subtract 15 on both sides:           3a = 15Divide 3 on both sides:                a = 5

What is wrong with this "proof"?"Theorem" For every positive integern, ifxandyare positive integers with max(x, y) =n,thenx=y.Basis Step: Suppose thatn= 1. If max(x, y) = 1 andxandyare positive integers, we havex= 1 andy= 1.Inductive Step: Letkbe a positive integer. Assume that whenever max(x, y) =kandxandyare positive integers, thenx=y. Now let max(x, y) =k+ 1, wherexandyare positiveintegers. Then max(x−1, y−1) =k, so by the inductive hypothesis,x−1 =y−1. Itfollows thatx=y, completing the inductive step.

Answers

Answer:

Every step is wrong in the proof theorem

Step-by-step explanation:

The inductive step :  whenever max(x, y) = k and x and y are positive integers, then x = y. is wrong because

If max (x,y ) = k + 1 then max ( x-1, y-1 ) = k

and by inductive hypothesis : x-1 = y-1 and x =y

example :

max ( 2, 3 ) = 3 where x = 2 , y =3

and x ≠ y hence the inductive step is wrong

Take 31 over to the other side so the equation looks like this

[tex]x = 66 - 31[/tex]

Then, solve for 66 - 31.

You will end up with x = 35.

devisibility rules for 3, 6, and 9

Answers

Answer:

Divisibility rule for 3 -

If the sum of all the digits divisible by 3 then the number is divisible by 3.

Here, we take an example for better understanding -

Example 1 - 3525

Add up the digits - 3 + 5 + 2 + 5

→ 15

As, 15 is divisible by 3. So, 3525 is a factor of 3.

Divisibility rule for 6 -

A number is to be divisible by 6 , if the number is also divisible by 2 and 3.

Example 2 - 132

Add up the digits = 1 + 3 + 2 = 6

As, 6 is divisible by 2 and it's also divisible by 3. Then, 132 is a factor of 6.

Divisibility rule for 9 -

If the sum of all the digits is divisible by 9 then the number is divisible by 9. Just like we'd in 3.

Example 3 - 1052

Add up the digits - 10 + 5 + 2 = 17

As, 17 is not divisible by 9. So, 1052 is also not divisible by 9.

(a) How many schedules are there?

(b) How many schedules include neither sister?

Answer:

a

   [tex]N  =  1,411,200[/tex]

b

  [tex]M  =  302, 400[/tex]

Step-by-step explanation:

From the question we are told that

   The  number of players in Taft High School is t =  8

    The  number of players in McKinley High School  is k = 7

   The number of rounds is  n  =  4

   The highest number of match each player can play is  w =  1

   

Generally the total number of schedules is  

      [tex]N  = ^tP_4 * ^k P_4[/tex]

      [tex]N  = ^8P_4 * ^7 P_4[/tex]

=>   [tex]N  =  \frac{8!}{(8-4)!} * \frac{7!}{(7-4)!}[/tex]

=>   [tex]N  =  \frac{8!}{4!} * \frac{7!}{3!}[/tex]

=>  [tex]N  =  \frac{8*7 *6*5*4*3*2*1}{4*3*2*1} * \frac{7*6*5*4*3*2*1}{3*2*1}[/tex]

=>  [tex]N  =  1,411,200[/tex]

Generally the  number of schedules that include neither of the sisters is  mathematically represented as

        [tex]M= \ ^{t-1}P_4 *\ ^ {k-1} P_4[/tex]

        [tex]M= \ ^{8-1}P_4 *\ ^ {7-1} P_4[/tex]

=>    [tex]M= \ ^{7}P_4 *\ ^ {6} P_4[/tex]

=>     [tex]M  =  \frac{7!}{(7-4)!} * \frac{6!}{(6-4)!}[/tex]

=>     [tex]M  =  \frac{7!}{3!} * \frac{6!}{2!}[/tex]

=>     [tex]M  =  \frac{7 *6*5*4*3*2*1}{3*2*1} * \frac{6*5*4*3*2*1}{2*1}[/tex]

=>      [tex]M  =  302, 400[/tex]

A researcher compares the effectiveness of two different instructional methods for teaching electronics. A sample of 138 students using Method 1 produces a testing average of 61. A sample of 156 students using Method 2 produces a testing average of 64.6. Assume the standard deviation is known to be 18.53 for Method 1 and 13.43 for Method 2. Determine the 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2. Step 1 of 2: Find the critical value that should be used in constructing the confidence interval.

Answers

Answer:

The 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 is (-8.04, 0.84).

Step-by-step explanation:

The (1 - α)% confidence interval for the difference between population means is:

[tex]CI=(\bar x_{1}-\bar x_{2})\pm z_{\alpha/2}\times \sqrt{\frac{\sigma^{2}_{1}}{n_{1}}+\frac{\sigma^{2}_{2}}{n_{2}}}[/tex]

The information provided is as follows:

[tex]n_{1}= 138\\n_{2}=156\\\bar x_{1}=61\\\bar x_{2}=64.6\\\sigma_{1}=18.53\\\sigma_{2}=13.43[/tex]

The critical value of z for 98% confidence level is,

[tex]z_{\alpha/2}=z_{0.02/2}=2.326[/tex]

Compute the 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 as follows:

[tex]CI=(\bar x_{1}-\bar x_{2})\pm z_{\alpha/2}\times \sqrt{\frac{\sigma^{2}_{1}}{n_{1}}+\frac{\sigma^{2}_{2}}{n_{2}}}[/tex]

     [tex]=(61-64.6)\pm 2.326\times\sqrt{\frac{(18.53)^{2}}{138}+\frac{(13.43)^{2}}{156}}\\\\=-3.6\pm 4.4404\\\\=(-8.0404, 0.8404)\\\\\approx (-8.04, 0.84)[/tex]

Thus, the 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 is (-8.04, 0.84).

Answer:

75 cm

Step-by-step explanation:

Given:

Perimeter of the triangular yield sign = 225 cm

Side lengths = x, x and x

Required:

Length of each side

SOLUTION:

Perimeter of the triangular yield sign = sum of all sides of the triangular yield sign

225 cm = x + x + x

Solve for x

225 = 3x

Divide both sides by 3

225/3 = 3x/3

75 = x

x = 75

The length big each side is 75 cm
