Answer:

Like I said from before, just make sire all the X’s are different for a function

DOn’t worry about the y, if there are repeating Ys, it doesn’t matter

If the each X is different from other Xs then its a function, if there are more then 1 x it’s not a function.

In This case the answer is

D or the last option

Answer:

(1,-1),(-3,-8),(8,-1),(0,5)

Step-by-step explanation:

(-3,1),(8,-2),(0,0),(8,6) is not a function

(-1,-8),(-8,-3),(-8,7),(4,1) is not a function

(-3,-8),(-3,-7),(2,-7),(6,-4) is not a function

(1,-1),(-3,-8),(8,-1),(0,5) has to be the function

Answer:

b. The margin of error would decrease.

Step-by-step explanation:

Margin of error of a confidence interval:

The margin of error of a confidence interval has the following format:

$M = z\frac{\sigma}{\sqrt{n}}$

In which z is related to the confidence level, $\sigma$ is the standard deviation of the population and n is the size of the sample.

This means that the margin of error is inversely proportional to the size of the sample, which means that if the sample size increases, the margin of error decreases.

In this question, the sample size is increased, leading to a smaller margin of error. So the correct answer is given by option b.

Step-by-step explanation:

when we perform each of these transformations, the only one that does NOT make shape F congruent (the same position, orientation and size) with shape G, for it reflects over and axis making it mirror to G, but is then ROTATED 90 degrees into shape G's sector, rotating the shape 90 degrees as well

Suppose a basketball player has made 184 out of 329 free throws. If the player make the next two free throws, I will pay you $24

Marta_Voda [28]

Given that the player made 184 out of 329 throws, the probability of making the next throw will be:
P(x)=[Number of shots made]/[Total number of throws]
=184/329
=0.559
Thus the expected value of proposition will be:
0.599*24+0.559*12
=20.134

A person spends 1/5 of his salary on rent, 3/7 on food, 1/3 on other expenses and saves the rest. If she earns $21,000 per month

sukhopar [10]

Answer:

$9600 saving / year

Step-by-step explanation:

1/5 of $21000 = 21000 / 5 = $4200 / month on rent

3/7 of $21000 = (21000 / 7) x 3 = $9000 / month on food (shocking right :) food is expensive)

1/3 of $21000 = 21000 / 3 = $7000 on other expenses / month

total savings/month = salary/month - rent/month - food/month - other expenses/month

total savings/month = 21000 - 4200 - 9000 - 7000

total savings/month = $800

BUT the question asks for savings per year. therefore, we must multiply the savings per month by total months per year (12)

800 x 12 = $9600

the person's total savings per year, with a salary of $21000 per month, is equal to $9600 per year
