Abigail can read 180 words in one minute if she were to read 30 minutes each day how many days would it take to read 32,400 word

Montano1993 [528]

Answer:

It would take Abigail six days to read 32,400 words of a book if she were to read 30 minutes per day.

Step-by-step explanation:

If Abigail reads 180 words per minute, and she reads 30 minutes per day, we need to multiply 180 by 30 to figure out how many words she reads per day.

180 × 30 = 5,400

Abigail reads 5,400 words per day.

Then, we divide 32,400 by 5,400 to figure out how many days it would take Abigail to read 32,400 words.

32,400 ÷ 5,400 = 6

It would take Abigail six days to read 32,400 days.

Hope that helped!

A poll of 1,000 randomly selected registered voters was taken and 680 responded that they favor candidate X for mayor (p 1 = 0.6

Zielflug [23.3K]

Answer:

The interval (-0.0199, 0.0510) represents the region of values where the true difference (in population terms now) between the initial proportion of registered voters that favour candidate X and the proportion of registered voters that favour candidate X just before election can take on with a confidence level of 90%.

Step-by-step explanation:

Confidence Interval for the population proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence. It is usually obtained from the sample.

p₁ represents the proportion of registered voters that favour candidate X in the initial poll, way before the election.

p₂ represents the proportion of registered voters that favour candidate X in the poll just before the election.

So, for this question the confidence interval for the true difference between the population proportion of registered voters that favour candidate X way before the elections and the population proportion that favour candidate X just before the election lies within (-0.0199, 0.0510) with a confidence interval of 90%.

Confidence interval is calculated mathematically as thus:

Confidence Interval = (Difference in Sample proportion) ± (Margin of error)

Margin of Error is the width of the confidence interval about the difference in the two sample proportions.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error)

Critical value = 1.645 (obtained from the z-tables because the sample size is large enough to ignore that information about the population standard deviation isn't given and t-critical value approximates z-critical value)

Hope this Helps!!!

Sarah averages 30 miles per hour driving from Tallahassee to Gainesville. What must her average speed be on the return trip if t

stiv31 [10]

Answer:

Explained

Step-by-step explanation:

average speed from Tallahassee to Gainesville is 30miles/hour

and the total average speed of the whole trip is 40 miles/hour

let the average speed in return journey be x miles per hour.

we know that if the distance is constant the average speed of the whole trip is given as

$S_{avg}= \frac{2S_1S_2}{S_1+S_2}$

$40=\frac{2\times30\times x}{30+x}$

on calculating we get x= 60 miles/hour

now, since the distance between two places is always constant, the result does not matter on the distance between two places. The average speed will remain the same.
