I agree with what that person told you. The expression -2(x+10) is equivalent to -2x-20

Multiply the outer -2 with the inner x to get -2 times x = -2x

Multiply the outer -2 with the inner term 10 to get -2 times 10 = -20

So overall, -2(x+10) = -2x-20

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

So that's how we're able to go from this -2(x+10) \ge 75 to this -2x-20 \ge 75

The only thing that changes is the left side. The inequality sign will not flip. It only flips if we multiply both sides by a negative number.

Answer:True

Step-by-step explanation:

Yes, you don't have to reverse the inequality symbol since the variables are not from the other side (right).

Convert the decimal number 183 into an equivalent 32 bit binary number. show all your work.
german
The bits are determined by repeated division by 2 to yield either 0 or 1.
 
183/2 = 91 rem 1  =>  1  (lowest bit)             2⁰
  91/2 = 45 rem 1  =>  1 (next higher bit)     2¹
  45/2 = 22 rem 1 => 1  (next higher bit)     2²
  22/2 = 11 rem 0  => 0 (next highrt bit)      2³
    11/2 = 5 rem 1    => 1 (next higher bit)     2⁴
     5/2 = 2 rem 1   => 1 (next higher bit)     2⁵
     2/2 = 1 rem 0   => 0 (next higher bit)    2⁶
     1/2 = 0 rem 1   => 1 (next higher bit)      2⁷
The next higher 24 bits have 0 in each bit.

For 32-bit system,
183 = 00000000 00000000 00000000 10110111 (with a space between bytes for readability)

Answer: 00000000000000000000000010110111

The following statements are all incorrect. Explain the statements and the errors fully using the probability rules discussed in
bija089 [108]

The reasons for each incorrect statement are as follows;

  1. The error in the statement is that, there might be other luckier numbers compared to number 7 and hence, the statement does not hold true for all numbers.
  2. The statement is incorrect because, there are 36 different possibilities and there are 5 possibilities of getting an 8.
  3. The statement is incorrect because, 93% does not necessarily represent a 93% chance of complete recovery as this is subject to other variables.
  4. The probability that they win is not 1/3 as it is subject to what the results have been over the years and not just the possible results.
  5. Since, the coin is unbiased, it follows that upon flipping the coin for the fifth time, it is not likely to have tails the next time it is flipped.
  6. The statement is incorrect because some students study during the week and weekends, hence, the conclusion is not correct.

<h3>What is Probability?</h3>

The term probability put simply is the ratio of the desired outcome to the possible outcomes. It therefore follows that probability as the name implies is used to predict the chance of an occurrence.

Mrs Smith has 12 times as many markers as color pencils the total number of markers and colored pencils is 78 how many markers d
yawa3891 [41]
<em>x = markers</em>
<em>y = colored pencils</em>

12x = y

x= 72
y = 6

Okay, so what I did was divide 78 by 12 (to find the number of colored pencils) which gave me 6.5. You can't have half a colored pencil, so I rounded the number down to get 6. To find the number of markers, I multiplied 12 and 6 <em>(12x = 6) </em>which gave me 72. To check my answer I added the two amounts, 72 + 6, which gave me 78.
