Write the values of the 9s in 990.250. How are the values related?

Answers

Answer 1

Answer:

Leftmost 9: 900

9 between 9 and 0: 90

9 on left is worth 10 times 9 on right.

Step-by-step explanation:

990.250

The 9 at the left is in the hundreds place, so it represents 9 hundreds, so its value is 900.

The 9 between the 9 and the 0 is in the tens place, so it represents 9 tens, and its value is 90.

Since the places are right next to each other, the 9 on the left is worth 10 times the 9 on the right. Sure enough, 900 is 10 times 90.

I scored 32 more points in my second unit test and I did it on my first my total points for both test were 164 what did I score on my two test

Answers

Answer:

a = 66 points (first test)

b = 98 (second test)

Step-by-step explanation:

Hi there !

a = first test

b = second test

a + b = 164

b = a + 32

replace b

a + (a + 32) = 164

2a = 164 - 32

2a = 132

a = 132 ; 2

a = 66 points (first test)

b = 66 + 32

b = 98 (second test)

Good luck !

1. Holly, Tyler, and their parents go shopping for some items to update their 3 bedrooms. They have exactly $400 that they can spend. They have the following items in their cart: 3 packages of curtains, 3 gallons of paint, and 3 lamp shades. Complete the following to find out if they have enough money to purchase these items and, if they do, how much they will have left over.
(a) If a package of curtains cost $21.50, what is the cost of the 3 packages of curtains in the cart?
(b) If a gallon of paint costs $7.96, what is the cost of the 3 gallons of paint in the cart?
(c) If a lamp shade costs $14.99, what is the cost of the 3 lamp shades in the cart?
(d) Find the total cost of all the items in the cart. Then, find the amount of money the family has left, if any, from the $400.

Answers

Answer:

3 x 21.50= 64.50

3 x 7.96= 23.88

3 x 14.99= 44.97

Altogether equals  133.35

400-133.35= 266.65

Answer:

3 x 21.50= 64.50

3 x 7.96= 23.88

3 x 14.99= 44.97

Altogether equals  133.35

3. A new process has been developed for applying pho­ toresist to 125-mm silicon wafers used in manufac­ turing integrated circuits. Ten wafers were tested, and the following photoresist thickness measurements (in angstroms x 1,000) were observed: 13.3987, 13.3957, 13.3902, 13.4015, 13.4001, 13.3918, 13.3965, 13.3925, 13.3946, and 13.4002. a. Test the hypothesis that mean thickness is 13.4 x 1,000 A. Use a = 0.05 and assume a two-sided alternative. b. Find a 99% two-sided confidence interval on mean photoresist thickness. Assume that thickness is normally distributed.

Answers

Answer:

a

The null hypothesis is  [tex]H_o : \mu  =  13.4000[/tex]

The alternative hypothesis is  [tex]H_a :  \mu \ne  13.4000[/tex]

The null hypothesis is rejected

b

The  99% confidence level is   [tex]13.3930  < \mu  < 13.3994 [/tex]

Step-by-step explanation:

From the question we are told that

  The sample size is  n =  10

   The  population mean is  [tex]\mu =  13.4 000 \  angstroms[/tex]

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

   The  sample data is  

13.3987, 13.3957, 13.3902, 13.4015, 13.4001, 13.3918, 13.3965, 13.3925, 13.3946, and 13.4002

Generally the sample mean is mathematically represented as

        [tex]\= x =  \frac{13.3987+ 13.3957\cdots +13.4002 }{10}[/tex]

=>     [tex]\= x = 13.3962 [/tex]

Generally the sample standard deviation  is mathematically represented as

    [tex]\sigma = \sqrt{\frac{\sum (x_i - \= x)^2}{n} }[/tex]

=> [tex]\sigma = \sqrt{\frac{ (13.3987 - 13.3962)^2 +  (13.3987 - 13.3962)^2 + \cdots + (13.3987 -13.4002)^2  }{10} }[/tex]

=>  [tex]\sigma =0.0039 [/tex]

The null hypothesis is  [tex]H_o : \mu  =  13.4000[/tex]

The alternative hypothesis is  [tex]H_a :  \mu \ne  13.4000[/tex]

Generally the test statistics is mathematically represented as

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

=>    [tex]z  =  \frac{13.3962 -  13.4000}{\frac{0.0039}{\sqrt{10} } }[/tex]

=>   [tex]z =  3.08[/tex]

Generally the p-value is mathematically represented as

       [tex]p-value  = 2P( z   >  3.08)[/tex]

From the z-table  [tex]P(z >  3.08)= 0.001035[/tex]

So

       [tex]p-value  = 2* 0.001035[/tex]

      [tex]p-value  = 0.00207[/tex]

So from the obtained value we see that

     [tex]p-value  < \alpha[/tex]

Hence the null hypothesis is rejected

Consider the b question

Given that the confidence level is  99%  then the level of significance is

    [tex]\alpha =  (100 -99)\%[/tex]

=> [tex]\alpha =  0.01[/tex]

Generally from the normal distribution table critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

    [tex]Z_{\frac{\alpha }{2} } =  2.58[/tex]

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } *  \frac{\sigma}{\sqrt{n} }[/tex]

=>   [tex]E = 2.58  *  \frac{0.0039}{\sqrt{10} }[/tex]

=>    [tex]E = 0.00318[/tex]

Generally the 99% confidence interval is mathematically represented as

     [tex]13.3962   - 0.00318  < \mu  < 13.3962   +  0.00318 [/tex]

=>   [tex]13.3930  < \mu  < 13.3994 [/tex]

Suppose a local manufacturing company claims their production line has a variance of less than 9.0. A quality control engineer decides to test this claim by sampling 35 parts. She finds that the standard deviation of the sample is 2.12. Is this enough evidence at the 1% level of significance, to accept the manufacturing companies claim? Calculate the appropriate test statistic (round to 2 decimal places as needed)

Answers

Answer:

The decision rule is  

   Fail to reject the null hypothesis

The conclusion is  

   There is no sufficient evidence to accept  the manufacturing company claims

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  35

   The sample standard deviation is  [tex]s =  2.12[/tex]

   The level of significance is [tex]\alpha = 0.01[/tex]

The null hypothesis is  [tex]H_o  :  \sigma ^2  = 9.0[/tex]

The alternative hypothesis is  [tex]H_a  :  \sigma ^2  <  9.0[/tex]

Gnerally the test statistics is mathematically represented as

    [tex]X^2 _{stat} =  \frac{(n -1) * s^2 }{\sigma^2 }[/tex]

    [tex]X^2 _{stat} =  \frac{(35  -1) * 2.12^2 }{9 }[/tex]

=> [tex]X^2 _{stat} =  16.98[/tex]

Generally the degree of freedom is mathematically represented as

   [tex]df =  n - 1[/tex]

=>    [tex]df =  35 - 1[/tex]

=>    [tex]df =  34[/tex]

From the chi - distribution table the  critical value of [tex]\alpha[/tex] at a degree of freedom of  [tex]df =  34[/tex] is  

     [tex]X^2_{\alpha, 34 } =56.060[/tex]

From the value obtained we see that the test statistics does not lie within the region of rejection (1.e 56.060 , [tex]\infty [/tex]   )

Then

The decision rule is  

   Fail to reject the null hypothesis

The conclusion is  

   There is no sufficient evidence to accept  the manufacturing company claims

A square garden and a hexagon garden have the same perimeter. The perimeter of the square garden is 4(x+7). The perimeter of the hexagon garden is 6(3x). What is the perimeter of each figure?

Answers

Answer:

36

Step-by-step explanation:

4(x+7) = 6(3x)

2(x+7) = 3(3x)

2x+14 = 9x

14 = 7x

x = 2

Plugging it back into the equation:

Hexagon = 6(3*2) = 6*6 = 36

Square = 4(2+7) = 4*9 = 36

Therefore, the perimeter of each figure is 36.

Step-by-step explanation:

you first find all the numbers that can go into the constant which is 10, so negative and positive 1 can go into 10, negative and positive 2 can go into 10 etc.

The possible rational roots of the polynomial equation

To find out possible rational roots, we use rational root theorem

Rational root of the form

[tex]\frac{p}{q}[/tex] where p is the constant and q is the leading coefficient

p=10  and q=2

Lets write all the factors of 10  and 2

Factors of 10 are 1,2,5,10

factor of 2 are 1,2

Rational root of the form
