Before I give you the answers, there is a simple rule to observe when rounding a number to two decimal places. If the number in the third decimal place is less than five, then the number in the second decimal place stays the same. If the number in the third decimal place is five or greater than five, the number in the second decimal place is incremented by one. In our case the above numbers are rounded up as follows:
0.273 is rounded up to 0.27
1.595 is rounded up to 1.60
6.473 is rounded up to 6.47
2.571 is rounded up to 2.57
0.425 is rounded up to 0.43
44.5564 is rounded up to 44.56
82.3643 is rounded up to 82.36
325.1741 is rounded up to 325.17
Answer:
D. 
Step-by-step explanation:
We have been given that a bag contains x blue chips and y red chips. The probability of selecting a red chip at random is 3/7. We are asked to find the
.



Since we are told that probability of selecting a red chip at random is 3/7, so red balls are 3 and total balls are 7:

Since total balls are 7, so we will get:

Upon substituting
in expression
, we will get:

Therefore, the value of
is
and option D is the correct choice.
2x+15=4x-1
16=2x
8=x
hope this helps!
Answer:
- 0.7
Step-by-step explanation:
We are given the general quadratic formula, as "
. " This can be represented by two separate formula's, which will come in handy when determining the positive and negative roots of the equation ( and here we need the negative root ):
1 )
,
2 ) 
We know that a = 1, b = - 5, and c = - 4 from the equation "
" ( which can be rewritten in the form
). Therefore, simply plug in these values into the quadratic formula to receive two solutions:
- This is our positive solution
__________
- And this is our negative solution
You can see that - 0.7 is the negative real number solution to Joline's quadratic equation!
