ch4aika [34]

Answer:

11 hrs 1 min (i think so based on math)

Step-by-step explanation:

If Johnna's reading rate is 150 words per min and there are 364 pages with about 275 words, you need to multiply 364 and 275 to get 100100 and divide that by 150 to get 667.3333333 round to the nearest tenth which will give you 667.3 and divide that by 60 because there are 60 minutes in an hour to get 11.12222222 and round that to the nearest tenth to get 11.1 which means it will take Johnna 11 hours and 1 minute to read the book.  I hope this is correct I'm really sorry if it isn't. :P

Why do the probability of an event and the probability of its complement add up to 1
Ad libitum [116K]
<span>the probability of an event and the probability of its complement add up to 1 because the total events are the even it self and its compliment, so its probability equal to 1 because these are all the possible events that will occur. for example a coin toss, an event head will happen 0.5, and its complement is tails which will also happens 0.5</span>

I need help on this question as soon as possible. If anybody can give me the correct answer I’ll give brainly. I just need help.
3241004551 [841]

Answer:

The solution of the system is (6, 9).

Step-by-step explanation:

Solve one of the variables and substitute the answer for the other variable.

Select one of the problems and solve for x.

3x+y=27

Subtract y from both sides.

3x+-y=27

Divide both sides by three.

x=1/3(-y + 27)

Multiply 1/3 by -y + 27.

x = -1/3y + 9

Replace -y/3 + 9 for x in the other problem 3x-2y=0.

3(-1/3y + 9) - 2y = 0

Multiply 3 by -y/3 + 9.

−y+27−2y=0

Add -y to -2y.

−3y+27=0

Subtract 27 from both sides of the problem.

−3y=−27

Divide both sides by −3.

y=9

Replace 9 for y in x=−1/3​y+9.

x=−1/3*9+9

Multiply −1/3​ times 9.

x=-3+9

Add 9 to -3.

x = 6.

x = 6, y = 9.

Ira Lisetskai [31]

Answer: $12 is % of $16.

Step-by-step explanation:

STEP 1: 100 ÷ 16 = 6.25

STEP 2: <u>12 x 6.25 </u>=  <u>75</u>

              16 x 6.25 = 100

Now we can see that our fraction is 75/100, which means that 12/16 as a percentage is 75%.

We can also work this out in a simpler way by first converting the fraction 12/16 to a decimal. To do that, we simply divide the numerator by the denominator:

12/16 = 0.75

Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:

0.75 x 100 = 75%

hope this helps!
