The Quality Control Department employs five technicians during the day shift Listed below is the number of times each technician

frutty [35]

Solution :

Number of different samples of two technicians possible is = 10, as 2 technicians are to be chosen from a total of 5 technicians.

a). Therefore, 10 different samples are possible of size two.

b).

Sample Shut down Mean

1. Taylor, Hurley 4, 3 3.5

2. Taylor, Gupta 4, 5 4.5

3. Taylor, Rousche 4,6 5

4. Taylor, Huang 4, 3 3.5

5. Hurley, Gupta 3,5 4

6. Hurley, Rousche 3,6 4.5

7. Hurley, Huang 3,3 3

8. Gupta, Rousche 5,6 5.5

9. Gupta, Huang 5,3 4

10. Rousche, Huang 6,3 4.5

Now mean of sample means $=\frac{42}{10}$ = 4.2

Mean of population is = $\frac{4+3+5+6+3}{5}$ = 4.2

Thus both the means are equal.

50=5x−3−8x−7 what is X?

Black_prince [1.1K]

Answer:

x = -20

Step-by-step explanation:

Solve for x:

50 = 5 x - 8 x - 7 - 3

Grouping like terms, 5 x - 8 x - 7 - 3 = (5 x - 8 x) + (-3 - 7):

50 = (5 x - 8 x) + (-3 - 7)

5 x - 8 x = -3 x:

50 = -3 x + (-3 - 7)

-3 - 7 = -10:

50 = -10 - 3 x

50 = -3 x - 10 is equivalent to -3 x - 10 = 50:

-3 x - 10 = 50

Add 10 to both sides:

(10 - 10) - 3 x = 10 + 50

10 - 10 = 0:

-3 x = 50 + 10

50 + 10 = 60:

-3 x = 60

Divide both sides of -3 x = 60 by -3:

(-3 x)/(-3) = 60/(-3)

(-3)/(-3) = 1:

x = 60/(-3)

The gcd of 60 and -3 is 3, so 60/(-3) = (3×20)/(3 (-1)) = 3/3×20/(-1) = 20/(-1):

x = 20/(-1)

Multiply numerator and denominator of 20/(-1) by -1:

Answer: x = -20
