What is the maximum value of the cube root parent function on −27 ≤ x ≤ 0?

Answers

Answer:

0

Step-by-step explanation:

Given an interval -27≤x≤0, to get the cube root of the maximum value, first we need to know the maximum value in the range. The maximum value between -27 and 0 will be 0 which is the greatest value in that interval.

Since the cube root of 0 is 0, the cube root of the maximum value within that range is 0.
The answer should be B.0.

What is 4 hours and 39 mins before 7:53 p.m

Answers

4 hours and 39 minutes before 7:53 p.m. is 6:34 p.m.

To find the time 4 hours and 39 minutes before 7:53 p.m., we can subtract the given time from the duration.

Step 1: Convert 4 hours and 39 minutes into minutes.

4 hours = 4 * 60 = 240 minutes

Total duration = 240 minutes + 39 minutes = 279 minutes

Step 2: Subtract the duration from the original time.

7:53 p.m. - 279 minutes

Subtract the minutes first:

53 minutes - 279 minutes = -226 minutes

Now, since the result is negative, we need to "borrow" an hour from the original time:

7 p.m. - 1 hour = 6 p.m.

So, 4 hours and 39 minutes before 7:53 p.m. is 6:34 p.m.

Jack wants to know how many families in his small neighborhood of 60 homes would help organize a neighborhood fund-raising party. He put all the addresses in a bag and drew a random sample of 30 addresses. He then asked those families if they would help organize the fund-raising party. He found that 12% of the families would help organize the party. He claims that 12% of the neighborhood families would be expected to help organize the party. Is this a valid inference? No, this is not a valid inference because he asked only 30 families No, this is not a valid inference because he did not take a random sample of the neighborhood Yes, this is a valid inference because he took a random sample of the neighborhood Yes, this is a valid inference because the 30 families speak for the whole neighborhood
