The compressive strength of concrete is being tested by a civil engineer who tests 12 specimens and finds that the sample mean i

ki77a [65]

Answer:

The 95% confidence interval for mean compressive strength is:

$3237.3\leq \mu\leq 3282.5$

Step-by-step explanation:

We have a sample of n=12 specimens, with sample mean=3259.9 and sample standard deviation = 35.57.

We know the population is normally distributed.

For a 95% confidence interval and df=n-1=11, the t-statistic is t=2.201.

Then, the CI can be expressed as:

$M-t*s/\sqrt{N}\leq \mu\leq M+t*s/\sqrt{N}\\\\3259.9-2.201*35.57/\sqrt{12}\leq \mu\leq 3259.9+2.201*35.57/\sqrt{12}\\\\ 3259.9-22.6\leq \mu\leq 3259.9+22.6\\\\3237.3\leq \mu\leq 3282.5$

A living room has a circular rug. According to a small tag, the rug has a circumference of 12.56 meters. What is the rug's diame

Anvisha [2.4K]

Answer:

4 m

Step-by-step explanation:

The circumference of a circle is the product of π and the diameter.

C = πd

12.56 m = 3.14d

d = 12.56 m/3.14 = 4 m

The rug's diameter is 4 meters.

Each month, you get your water bill in the mail. You know that each month you are charged a service

Svetach [21]

Answer:

$0.004 per gallon

Step-by-step explanation:

Given:

Service Fee= $22

Fixed rate per gallon= m

Water Consumed= 2256 gallons

Total bill charged= $31.02

Now by computing the equation we get

$\textrm{Total bill charged} = \textrm{Service fee} + (\textrm{fixed charge per gallon} \times \textrm{water consumed})$

Substituting data we get

$22+m2256=31.02$

$m2256= 31.02-22$

$m2256=9.02$

$\therefore m =\frac{9.02}{2256} =0.00399$

Rounding off above value we get

$m=0.004$ per gallon
