Hypothesis = It rains
Conclusion = The game is canceled
=====================================================
Explanation:
The general format for a conditional is "If P, then Q".
P is the hypothesis and Q is the conclusion. They are placeholders.
In this case
- P = It rains
- Q = The game is canceled
Some textbooks will write
to indicate "if P, then Q"
The distribution of X is X ~ N (20 , 6) and the probability that this American will receive no more than 24 Christmas cards this year is 0.7486.
<h3>Probability</h3>
a. Distribution
X ~ N (20 , 6)
b. P(x ≤24)
= P[(x - μ ) / σ (24 - 20) / 6]
= P(z ≤0.67)
= 0.74857
=0.7486
Hence:
Probability = 0.7486
c. P(21 < x < 26)
= P[(21 - 26)/ 6) < (x - μ ) / σ < (24 - 20) / 6) ]
= P(-0.83 < z < 0.67)
= P(z < 0.67) - P(z < -0.)
= 0.74857- 0.2033
= 0.54527
Hence:
Probability =0.54527
d. Using standard normal table ,
P(Z < z) = 66%
P(Z < 0.50) = 0.66
z = 0.50
Using z-score formula,
x = z× σ + μ
x = 0.50 × 6 + 20 = 23
23 Christmas cards
Therefore the distribution of X is X ~ N (20 , 6) and the probability that this American will receive no more than 24 Christmas cards this year is 0.7486.

Answer:
x=3
y=13
Step-by-step explanation:
okay so what that means is that the two equations are y=-x+16 and y=3x+4
so y+x=16
y-3x=4
so 4x=12 so x=3
y=13 is the solution
