10-\frac{3x-1}{2} =\frac{6x+3}{11}

10 = \frac{6x+3}{11} + \frac{3x-1}{2}

10 = (\frac{6x+3}{11} \times  \frac{2}{2} ) + (\frac{3x-1}{2} \times  \frac{11}{11} )

10 = ( \frac{2(6x + 3)}{22} ) + ( \frac{11(3x - 1)}{22} )

10 =  \frac{12x + 6}{22}  +  \frac{33x - 11}{22}

10 =  \frac{12x + 6 + 33x  - 11}{22}

10 =  \frac{(12 x + 33x) + (6 - 11)}{22}

10 =  \frac{45x - 5}{22}

10 \times 22 = 45x - 5

220 = 45x - 5

220 + 5 = 45x

225 = 45x

\frac{225}{45}  = x

\frac{45}{9}  = x

5 = x

5 4/8 + 1 3/8 =<br> 1. 33/8<br> 2. 55/8<br> 3. 6 7/16
Dovator [93]

Answer: 2. 55/8

Step-by-step explanation: Add the whole numbers first (5+1 = 6), then add the fractions (4/8 + 3/8 = 7/8). Now we have 6 7/8 and since they want the answer in fraction form we will multiply the 6 and the 8 (6x8=48) and then add the 7 to the 48 (7+48 =55) and we leave our answer over the denominator which is 8. This leaves us with the final answer of 55/8

Statistics question; please help.
Alex_Xolod [135]

Answer:

Does this sample provide convincing evidence that the machine is working properly?

Yes.

Step-by-step explanation:

<u>Normal distribution test:</u>

$z=\frac{x- \mu }{ \frac{\sigma}{\sqrt{n}} }=\frac{ (x-\mu)\sqrt{n}}{\sigma}  $

Where,

x: \text{ sample mean}

\sigma: \text{ standard deviation}

n: \text{ sample size determination}

\mu: \text{ hypothesized size of the screw}

$z=\frac{(1.476-1.5)\sqrt{200} }{0.203 } $

$z=\frac{(-0.024)10\sqrt{2} }{0.203 } $

z \approx -1.672

Once the significance level was not given, It is usually taken an assumption of a 5% significance level.

Taking the significance level of 5%, which means a confidence level of 95%, we have a z-value of \pm 1.96

Therefore, we <u>fail to reject the null</u>. It means that the hypothesis test is not statistically significant: the average length is not different from 1.5!

What is the prefix in regroup? what dose it mean?
kupik [55]
The prefix in the word "regroup" is "re" and it means "again". Separate the words like this (re)read to find the "prefix" 

Just think when your teacher ask you to reread the book or the problem.It should come to mind as "Read again" 

Good Luck!
