10-3 2/5
First I'll do it with decimals and then fractions :)
10-3 2/5 is the same as 10-3.4 which is 6.6.
With fractions you can do:
10-3 2/5 is the same as 10-3 4/10 and also 100/10-34/10
100-34=66 so it would be 66/10 or 6 6/10 simplified to 6 3/5

Hope this helps :)

-Multiply the denominator and the middle number, then add nominator into that product. In this case, denominator = 5, middle number = 3 , nominator = 2. So, 5 times 3 is 15. Then add 15 to the nominator 2. Thus 15+2 = 17. The new nominator will be 17. After that, follow the simple arithmetic. 
10- 17/5 =
10 - 3.4 = 6.6

VladimirAG [237]

Answer:

Margin of error  for a 95% of confidence intervals is 0.261

Step-by-step explanation:

<u>Step1:-</u>

 Sample n = 81 business students over a one-week period.

 Given the population standard deviation is 1.2 hours

 Confidence level of significance = 0.95

 Zₐ = 1.96

Margin of error (M.E) = \frac{Z_{\alpha  }S.D }{\sqrt{n} }

Given n=81 , σ =1.2 and  Zₐ = 1.96

<u>Step2:-</u>

<u />Margin of error (M.E) = \frac{Z_{\alpha  }S.D }{\sqrt{n} }<u />

<u />Margin of error (M.E) = \frac{1.96(1.2) }{\sqrt{81} }<u />

On calculating , we get

Margin of error = 0.261

<u>Conclusion:-</u>

Margin of error  for a 95% of confidence intervals is 0.261

2X+2Y=48<br> 3X+Y=40 <br><br> What is X and Y
marshall27 [118]

Answer:

x=8

y=16

Step-by-step explanation:

2x+2y=48

3x+y=40

Ther is many ways to solve this, one of them is clearance:

WE CLEAR AN UNLOCKED (X) AND REPLACE IT IN THE OTHER

x= (40-y)/3

2[(40-y)/3] +2y=48

(80-2y)/3 +2y=48

(80-2y+6y)/3=48

80+4y=48(3)

4y=144

y= 144/4

y=16

x=(40-y)/3

x=(40-16)/3

x=24/3

x=8
