3*6.022*10^23 no of molecules in 3.0 moles of sucrose
Answer:
Step-by-step explanation:
<u>The balls - multiples of 3 are:</u>
<u>The probability of a multiple of 3 is:</u>
- 3 out of 10 or
- P = 3/10 = 30%
30% probability is in the range 0%-50% so this event is unlikely

(b)
the price of 50 cloud markers is $37.2
Step-by-step explanation:
(a)
Let's assume
price is P
number of markers is N
We are given
The price of a box of 15 cloud markers is $12.70
so,
The price of a box of 42 cloud markers is $31.60
so,
Firstly, we will find slope
now, we can plug values
now, we can use point slope form of line
we can plug value
now, we can solve for P
add both sides by 12.70
(b)
now, we can plug N=50
So,
the price of 50 cloud markers is $37.2
Answer:
m = -2
Step-by-step explanation:
To get the slope of the line, we are going to use the 2-points slope equation form
That will be;
m = (y2-y1)/(x2-x1)
(x1,y1) = (-5,11)
(x2,y2) = (8,-15)
m = (-15-11)/(8-(-5)) = -26/13 = -2
The possible mistake she might have made is placing the x-values difference over the y and her formula will look like;
m = (x2-x1)/(y2-y1)
It is an error of switching the numerator for the denominator
