Answer:

About 31 days

Step-by-step explanation:

We are given that

Distance traveled by Shannon=2,912 miles

She travels distance per day=About 95 miles

We have to find  number of days taken by Shannon to complete the race.

To find the number of days taken by Shannon to complete the race we will find the time taken by Shannon to complete 1 mile distance

Shannon takes time to cover  about 95 miles distance=1 day

Shannon takes time to cover  1 mile distance=\frac{1}{95} day

Shannon takes time to cover  2,912 miles distance =\frac{1}{95}\times 2,912

Shannon takes time to cover  2,912 miles distance=30.65 days\approx 31 days.

Hence, Shannon takes time to complete the race=about 31 days

melisa1 [442]

Answer:

Step-by-step explanation:

Given that a survey was conducted that asked 1004 people how many books they had read in the past year.

Results are:

x bar =12.5

s = 16.6

n = 1004

Std error of sample = \frac{s}{\sqrt{n-1} } =\frac{16.6}{\sqrt{1003} }\\=0.524152\\=0.524

Since population std dev is not known t critical value can be used for confidence interval.

df = 1004-1 =1003

t critical = 1.96

Margin of error = 1.96(std error) =1.027

Confidence interval lower bound = 12.5-1.027 = 11.473

Upper bound = 12.5+1.027 = 13.527

Nezavi [6.7K]

Answer:

CBD = 63 degrees

Step-by-step explanation:

To find CBD, we must first find the value of x. To do so, we use this equation since CBD and ABC equal 96 degrees:

(6x+27) + (7x-9) = 96
13x+18 = 96
13x+18-18 = 96-18
13x = 78
13x/13 = 78/13
x = 6

Now that we know the value of x, we factor it in to CBD to find its true value:

6x+27
6(6)+27
36+27
= 63 degrees

To check if this answer is correct, we can also find the value of ABC and see if the two values equal 96:

7x-9
7(6)-9
42-9
= 33 degrees

63 + 33 = 96

The answer is correct. CBD = 63 degrees and ABC = 33 degrees.
