Answer:

It could be many things.

Step-by-step explanation:

If you are rounding to the nearest ten it would be 30. If you're rounding the the nearest whole number you don't change the 25 at all. If you are rounding the the nearest 20 it would be 20. If you're rounding to an even number you could round up or down to get 26 or 24. Normally you would round up in that situation so you would use 26. I think in this specific situation they want it rounded to the nearest ten. In that case it would be 30.

What is the answer cos75 degrees=10/x

vova2212 [387]

To find the answer we simply work out the equation.
cos (75) = 10/x

cos (75) * x = 10. Here, I simply multiplied both sides by x to move x to the left hand side of the equation.

x = 10 / cos (75) Here, I divided cos (75) on both sides to move cos (75) to the right hand side of the equation.

The cosine of 75 is 0.92175127, so, 10 / 0.92175127 = 10.8489137

Suppose a normal distribution has a mean of 50 and a standard deviation of 3. What is P(x≤53)?

Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

Use the formula to find the z-score, then go to the table that will give you the probability that the value is less than this z-score.

$z=\frac{53-50}{3}=1$

The probability that the value lies to the left of 1 on a standard bell curve is 84.1345%, or 84%, the third choice down.

An online poll has a question that appears on the screen, and you simply click buttons to vote "Yes, " "No, " "Not sure, " or "D

Nataly_w [17]

Complete Question

An online poll has a question that appears on the screen, and you simply click buttons to vote "Yes, " "No, " "Not sure, " or "Don't care." On a particular day, the results of a question were tallied. In all, 636 said "Yes, " another 595 said "No, " and the remaining 93 indicated that they were not sure.

What is the sample size for this poll?

Compute the percent of responses in each of the possible response categories. (Round your answers to two decimal places.)

Discuss the poll in terms of the population and sample framework that we have studied in this chapter.

This random sample of responses collects the opinions of a random group of users across all users of the Internet.

ii)

This voluntary response sample collects only the opinions of those that visit this site every day.

iii)

This random sample of responses collects the opinions of a random group of users of the particular site.

iv)

This voluntary response sample collects only the opinions of those who visit this site and feel strongly enough to respond.

Answer:

$n = 1324$

YES $y = 48.03 \%$

NO $m =44.94 \%$

NOT SURE $m =7.02\%$

The correct option is (iv)

Step-by-step explanation:

From the question we are told that

The voting options are "Yes, " "No, " "Not sure, " or "Don't care."

The number of people that said is $Y = 636$

The number of people that said No is $N = 595$

The number that indicated Not sure is $S = 93$

Generally the sample size is mathematically represented as

$n = Y + N + S$

=> $n = 636 + 595 + 93$

=> $n = 1324$

Generally the percentage of responses that was Yes is mathematically represented as

$y = \frac{636}{ 1324} * 100$

=> $y = 48.03 \%$

Generally the percentage of responses that was No is mathematically represented as

$m = \frac{595}{ 1324} * 100$

$m =44.94 \%$

Generally the percentage of responses that was Not sure is mathematically represented as

$s = \frac{93}{ 1324} * 100$

$m =7.02\%$

This voluntary response sample collects only the opinions of those who visit this site and feel strongly enough to respond.
