Answer:

1.125

Step-by-step explanation:

1) First you have to turn it into an improper fraction

8*1 = 8. Add the numerator--> 8+1 = 9.

2) The improper fraction is 9/8

3) Divide 9 by 8

 **Write this using long division

8 goes into 9 one time, so we will write one as our first digit

Carry down the 1 and the 0, 8 goes into 10 1 times so write 1.

And this point we have 1.1 above

Carry down the 2 and the 0, 8 goes into 20 2 times so write 2

At this point we have 1.12

Carry down the 4 and the 0, 8 goes into 40 5 times with no remainders so write 5 and end the division process.

Now we have 1.125 as our decimal for 9/8 which is equivalent to 1 1/8.

krok68 [10]

Answer:

The 99% confidence interval for the difference between the true average load for the fiberglass beams and that for the carbon beams is (-11.937, -6.863).

Step-by-step explanation:

We have to calculate a 99% confidence interval for the difference between the true average load for the fiberglass beams and that for the carbon beams.

The sample 1 (Fiberglass), of size n1=26 has a mean of 33.4 and a standard deviation of 2.2.

The sample 2 (Carbon), of size n2=26 has a mean of 42.8 and a standard deviation of 4.3.

The difference between sample means is Md=-9.4.

M_d=M_1-M_2=33.4-42.8=-9.4

The estimated standard error of the difference between means is computed using the formula:

s_{M_d}=\sqrt{\dfrac{\sigma_1^2}{n_1}+\dfrac{\sigma_2^2}{n_2}}=\sqrt{\dfrac{2.2^2}{26}+\dfrac{4.3^2}{26}}\\\\\\s_{M_d}=\sqrt{0.186+0.711}=\sqrt{0.897}=0.9473

The critical t-value for a 99% confidence interval is t=2.678.

The margin of error (MOE) can be calculated as:

MOE=t\cdot s_{M_d}=2.678 \cdot 0.9473=2.537

Then, the lower and upper bounds of the confidence interval are:

LL=M_d-t \cdot s_{M_d} = -9.4-2.537=-11.937\\\\UL=M_d+t \cdot s_{M_d} = -9.4+2.537=-6.863

The 99% confidence interval for the difference between the true average load for the fiberglass beams and that for the carbon beams is (-11.937, -6.863).
