<u>Answer</u>


Option C ,D and E



<u>Explanation</u>



Any time we divide an inequality by a negative number, we reverse the sign



The first error is that,


She did not change the sign > to <



Another mistake is that, she divided one side by -5 and multiplied the second by -5



Also whenever an inequality involve < or > we use an open circle on the number line.



So another mistake is that,



She used a closed circle instead of an open circle on the number line




The correct thing should have been



-5x-3.5\:>\:6.5




-5x\:>\:10





x\:




The number line is shown in the attachment.

Jerome is cooking dinner. He needs 8 ounces of broccoli for each person.
Serga [27]
Due to the fact he does not know how many people are attending, you would represent the people value with a variable. Because we know he's given 8 ox. per person, you would need to write the expression as 8x.8 to represent the ox. needed and the x representing the people.

Divide 32 by 8 to see how many people he can serve,
32/8=4

PLEASE HELP :( I HATE SCHOOL
liberstina [14]

Answer:

100= 10+ 16t

Step-by-step explanation:

If beginning at 10 percent you initially are only in need for 90% charge. Earning 16% every thirty minutes you can initially do x4 for two hours on the charger and know you aren't at 100 yet. (16x4)+10= 64+10= 74. 100-74= 26. You need one more hour (total of 6 half hours) on the charger.

Another way of doing it could be 16÷90 and getting 5.blahblahblah and rounding up.

Consider a fair coin, such that the probability of observing a head or a tail in a random toss is 0.5. Consider an experiment in
Mariulka [41]

Applying probability concepts, it is found that the correct statements are:

  • c) pa and pb are not equal
  • d) pa is 2/3 and pb is 1/3

-------------------------------------------

  • A probability is the number of desired outcomes divided by the number of total outcomes.

The sample space, that is, the possible outcomes for the coin tosses is given next, considering H for heads and T for tails.

H - H

H - T

T - H

T - T

-------------------------------------------

  • Considering that there is at least 1 tails, the new sample space is:

H - T

T - H

T - T

  • pa: probability of one head, two outcomes with 1 head out of three, thus, pa = 2/3.
  • pb: probability that the second is tails, so one outcome(T - T) out of three, thus pb = 1/3.

-------------------------------------------

The correct statements are:

  • c) pa and pb are not equal
  • d) pa is 2/3 and pb is 1/3
