On the basis of extensive tests, the yield point of a particular type of mild steel-reinforcing bar is known to be normally dist
KiRa [710]
1) The formula used for determining the confidence interval is
Sample mean +/- Critical value (or z-score corresponding to 90% confidence) * Standard
error of mean
8439 +/- 1.645 * 100/sqrt 25
8439 +/- 1.645 * 20
8439 +/- 32.9
2) The only difference in this case is finding the critical value i.e., z-score corresponding to 92% confidence which is 1.75 approximately
Then the confidence interval is
8439 +/- 1.75 * 100/sqrt 25
8439 +/- 1.75 * 20
8439 +/- 35
Lower limit is 8439 - 35 = 8404
The upper limit is 8439 + 35 = 8474

28    -5       25
34     1         1
42     9        81
52     19      361
           SUM 828

(d) Take the sum of 828 and divide it by 6 to get 138.  Now take the square root of 138 to get the standard deviation:

sqrt(138) ≈ 11.75

What is the value of y in the system of equations 6x-y=2 and 4x-y=-8
uysha [10]

Answer:

y=28

Step-by-step explanation:

6x-y=2

-y=2-6x

y=6x-2

4x-(6x-2)=-8

4x-6x+2=-8

-2x=-10

x=5

y=6*5-2=30-2=28

y=28
