Answer:
Step-by-step explanation:Here the slope of the line = m = 2
The line passes through the point (
x
1
, y
1
) = ( , 9
).
The equation of the line with slope m and passing through the point (
x
1
, y
1
) is given by
(
y
- y
1
) = m (
x - x
1
)
(
y - 9
) = 2 ( x - 3
)y - 9 = 2
x - 6
Collecting terms in one side
0 = 2
x - y - 6 + 9
2
x - y + 3 = 0
Hope this helps x
Answer:
Expected number of guests is 100.4.
Step-by-step explanation:
It is given that there are 161 guest if there is a heavy snow fall.
Also, the probability for a heavy snow fall is 0.40.
Therefore, P(X = 161) =0.4.
It is also given that there are 60 guests if there is a light snow fall.
The probability for a light snow fall is 1 - 0.4 = 0.6.
Therefore, P(X = 60) = 0.6.
Expected number of guests = (161)P(X = 161) + (60)P(X = 60)
= 161(0.4) + 60(0.6)
= 64.4 + 36
= 100.4
Answer:
x = 3
Step-by-step explanation:
The equation is,
16 = 5x+1
Subtract 1 from both sides,
16-1 = 5x
15 = 5x
Divide by 5,
x = 3
