Answer:
The number is 0
Step-by-step explanation:
We form an equation using the statement:
8 = 7x + 8
Then we solve it:
8 = 7x + 8
8 - 8 = 7x
0 = 7x
0 ÷ 7 = x
x = 0

Answer:
0.227
Step-by-step explanation:
Given that X is binomial with n=7 and p =0.5
To find the probability for P(X<3)
i.e. we have to find prob as =P(x=0,1,2)
=P(X=0)+P(X=1)+P(x=2)
P(X=r)=7Cr(0.5)^7
Using binomial table we find prob
P(X<3)=0.2265
Round off this to 3 decimals as
0.227
Hence answer is 0.227
'Parallel' means parallel TO something else. A single line all by itself
is not "a parallel line", until we know the other line that it's parallel TO.
There are an infinite number of lines that pass through (0, -2).
Give us another line, and we'll find the one that's parallel to it.
