it is not a constant line

Step-by-step explanation:

each x value increases by 1, but the y values are all over the place and are in no order.

Answer:

for the line to have a constant slope, the difference of every y- ordinate with the last ordinate has to be equal

to check this, we will use the following formula

y4 - y3 = y2 - y1

if both the LHS and the RHS are equal, the slope is constant and is irregular otherwise

5 - 8 = 7 - 3

-3 = 4

LHS ≠ RHS

Since LHS is not equal to RHS, the slope is NOT constant and hence keeps increasing or decreasing irregularly

Therefore, option 4 (Not a line) is correct

Answer:

b. It will decrease by a factor of 2

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 lower end of the interval is given by:

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

The upper end of the interval is given by:

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

The length of the interval is the subtraction of the upper end by the lower end, so it is:

$L = 2z\sqrt{\frac{\pi(1-\pi)}{n}}$

This means that the length is inverse proportional to the square root of the size of the sample.

So, if the sample size is multiplied by 4, the length of the interval is going to decrease by a factor of 2.

Algebra 2 word problem: Urgent!

vesna_86 [32]

Answer:

180 hours

Step-by-step explanation:

Surfer #1 takes a capsule every 6 hours, but this is also equal to 2 capsules every 12 hours. Surfer #2 takes 1 capsule every 12 hours. Thus, both surfers take a total of 3 capsules every 12 hours.

By dividing 45 total capsules they need to consume by 3, the number of capsules the surfers consume every 12 hour, you get the total number of hours times 12 it takes for them to consume 45 capsules. 45 / 3 = 15, so it takes 15 * 12 hours for them to consume 45 capsules. This is equal to 180 total hours.

Arrange the given steps in the correct order to find A and B if A and B are two sets where A – B = {1, 5, 7, 8}, B – A = {2, 10}

GarryVolchara [31]

Answer:

A = {1, 3, 5, 6, 7, 8, 9}

B = {2, 3, 6, 9, 10}

Step-by-step explanation:

Here as given in the question:

A – B = {1, 5, 7, 8} ⇒ {1, 5, 7, 8} is in A not in B.

B – A = {2, 10} ⇒ {2, 10} is in B not in A

A ∩ B = {3, 6, 9} ⇒ {3, 6, 9} is BOTH in A and B.

Step 1:

Set A can also be expressed as : A = (A - B) ∪ (A ∩ B)

Set A can also be expressed as : B = (B - A) ∪ (A ∩ B)

Step 2:

Substituting the values of (A - B) and (B - A)

A = {1, 5, 7, 8} ∪ {3, 6, 9}

B = {2, 10} ∪ {3, 6, 9}.

Step 3:

Finding the UNION of the above two sets, we get:

A = {1, 3, 5, 6, 7, 8, 9}

B = {2, 3, 6, 9, 10}
