The probability that it will rain tomorrow and the football game will be postponed is 16% option (B) 16% is correct.
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that;
There is an 80% chance of rain tomorrow and a 20% chance the football game will be postponed.
P(rain) = 80%
In decimal
P(rain) = 0.80
P(football game will be postponed) = 20%
In decimal:
P(football game will be postponed) = 0.20
The probability that it will rain tomorrow and the football game will be postponed:
P= P(rain)xP(football game will be postponed)
P = 0.80x0.20
P = 0.16
In percent; multiply it by 100
P = 0.16x100
P = 16%
Thus, the probability that it will rain tomorrow and the football game will be postponed is 16% option (B) 16% is correct.

Answer:
16%
Step-by-step explanation:
80%=0.8
20%=0.2
0.8*0.2=0.16=16%
y = 4x - 1
b) 2x + y = 8
4x + 3y = 16
c) -3x + 2y = 19
4x + 5y = 13
d) -3x + 7y = 9
4x - 3y = 7
e) -4x + 5y = -7
x = 23 - 3y
f) y = -x
y = -2/5x - 1/5
Good evening ,
Look at the photo below for the answer.

Answer:
a) x = 1 , y = 3
Step-by-step explanation:
a) 7x + 3y = 16
y = 4x - 1
or
3y + 7x = 16 ... (i)
y - 4x = -1 ... (ii)
Solving the simultaneous equation by substitution;
Equation (ii) tells us that y = 4x - 1
Substituting that in (i) gives;
3(4x - 1) + 7x = 16
12x - 3 + 7x = 16
19x = 16 + 3 = 19
x = = 1
y = 4(1) - 1 = 3
