Answer:
p=7/2
Step-by-step explanation:
Rember that a p series can be represented by
Here, notice that
This is true for all parts of the series because
So p=7/2
Answer:
x= -2, y = -2
Step-by-step explanation:
Solve the following system:
{2 y - 4 x = 4 | (equation 1)
{4 x - y = -6 | (equation 2)
Add equation 1 to equation 2:
{-(4 x) + 2 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by 2:
{-(2 x) + y = 2 | (equation 1)
{0 x+y = -2 | (equation 2)
Subtract equation 2 from equation 1:
{-(2 x)+0 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by -2:
{x+0 y = -2 | (equation 1)
{0 x+y = -2 | (equation 2)
Collect results:
Answer: {x = -2
, y = -2
We know that
total <span>pieces of balsa wood in a box---------------- > 30
</span><span>pieces 15 in lon----------------------------------------> 4
</span>pieces 12 in lon----------------------------------------> 10
pieces 8 in lon----------------------------------------> (30-(10+4))=16
Let
P---><span>the probability the builder will pull an 8 inch piece from the box without looking
P=(</span>pieces 8 in lon)/(total pieces)=16/30=0.5333=53.33%
the answer is 53.33%
I would say the answe would be 4 units between P and T.
