Answer:
X= 24º
Explanation:
A straight line is 180º so, 180º - 151º = 29º - 5º = 24º
There are 
ways of getting exactly 5 heads in 10 tosses. There are 
possible outcomes. So the probability of getting exactly 5 heads is
You want y? One way to get y alone would be to mult. all 3 terms by (7/5):
(7/5)(5/7)y = (7/5)*3 - (7/5)(-1/5). This simplifies to:
y = 21/5 * 7/25, or y = 147 / 125.
You could check this using decimal fractions:
y = 4.20 * 0.28 = 1.176 = 147 / 125.
Answer:
x=9, y=0. (9, 0).
Step-by-step explanation:
y=-3x+27
6y-x+9=0
-----------------
6(-3x+27)-x+9=0
-18x+162-x+9=0
-19x+171=0
-19x=0-171
-19x=-171
19x=171
x=171/19
x=9
y=-3(9)+27=-27+27=0
Answer:
10
Step-by-step explanation:
2/3x15
as 3 and 15 are multiples they can be cancelled.
so 2x5=10
