Answer:
5
Step-by-step explanation:
y=Kx is the equation for proportions, k being constant, so k=5
Answer:
0.17189
0.3504
Step-by-step explanation:
For a fair coin ; p = 0.5
1 - p = 0.5
P(x < 4) = p(x = 0) + p(x =1) + p(x = 2) + p(x = 3)
Recall:
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Using a calculator to save time:
P(x <4) = 0.00098 + 0.00977 + 0.04395 + 0.11719
P(x < 4) = 0.17189
For a unfair coin :
p = 0.3 ; 1 - p = 1 - 0. 3 = 0.7
P(x ≥ 4) = p(x=4)+p(x =5)+p(x=6)+p(x=7)+p(x=8)+p(x=9) +P(x=10)
Recall:
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Using a calculator to save time:
P(x ≥4) = 0.3504
The expression will be 20°F - (-12°F)
From the information given, the highest and lowest temperature are represented below:
Highest temperature = 20°F
Lowest temperature = -12°F
Therefore, the difference between the highest and the lowest temperature will be:
= Highest temperature - Lowest temperature
= 20°F - (-12°F)
= 20°F + 12°F
= 32°F

Slope is 2/6 also 1/3
Y=Mx+b
5=1/3*-9+b
5=-3+b
b=8
So the equation is y= 1/3x +8
