Jenny tweets 33 times a day. antonio posts 5 tweets per day. let d represent the number of given days. use an algebraic expressi
algol13
Jenny's algebraic expression:

y = 33d

where y is the total number of posts

total tweets in 5 days

y = (33)(5)

y = 165 tweets

Antonio's expression:

y = 5d

total tweets in 5 days

y = (5)(5)

y = 25 tweets

Altogether they have posted:

165 + 25 tweets = 190 tweets in five days

What is the sum of 2/5 and 3/4 what is the answer​
vfiekz [6]

Answer:

23/20 or 1 and 3/20

Step-by-step explanation:

Make sure they have the same common denominator. For 5 and 4, 20 would be the Least Common Denominator.

so 2/5=8/20 and 3/4=15/20

Add 8+15 and you get 23 so 23/20 you can leave it so or switch it to a mixed number 1 3/20

Katrina wants to estimate the proportion of adults who read at least 10 books last year. To do​ so, she obtains a simple random
kicyunya [14]

Answer:

D. Matthew's estimate will have the smaller margin of error because the larger sample size more than compensates for the higher level of confidence

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence interval 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error is the division by 2 of the upper level of the interval \pi + z\sqrt{\frac{\pi(1-\pi)}{n}} by the lower level \pi - z\sqrt{\frac{\pi(1-\pi)}{n}}, so this is

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

Both Katrina and Matthew are working with the same population, so \pi is equal for both.

Katrina

Katrina wants to estimate the proportion of adults who read at least 10 books last year. To do​ so, she obtains a simple random sample of 100 adults and constructs a​ 95% confidence interval. This means that she has z = 1.96 and n = 100. So her margin of error is

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

M = (1.96)\sqrt{\frac{\pi(1-\pi)}{100}}

M = 0.196\sqrt{\pi(1-\pi)}

Matthew

He obtains a simple random sample of 400 adults and constructs a​ 99% confidence interval.

This means that, for Matthew, z = 2.575, n = 400. So his margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

M = (2.575)\sqrt{\frac{\pi(1-\pi)}{20}}

M = 0.12875\sqrt{\pi(1-\pi)}

Higher confidence levels usually led to higher margins of error. However, Matthew's larger sample size compensates his higher confidence level.

So the correct answer is:

D. Matthew's estimate will have the smaller margin of error because the larger sample size more than compensates for the higher level of confidence
