The value of P(4<X≤12) is 0.45
<h3>How to determine the probability?</h3>
The complete question is added as an attachment
To calculate P(4<X≤12), we use the following equation
P(4<X≤12) = P(4<X≤8) + P(8<X≤12)
From the histogram, we have:
P(4<X≤8) = 0.1
P(8<X≤12) = 0.35
So, we have:
P(4<X≤12) = 0.1 + 0.35
Evaluate
P(4<X≤12) = 0.45
Hence, the value of P(4<X≤12) is 0.45

Answer:
x = 5km/h
Step-by-step explanation:
If he walks 5km/h, he would reach 30km in 6hrs. However, if he walks 1km/hr faster which is 6km/h, he wouls reach 30km in 5hrs. This meaning he can complete the same distance 1 hour faster. Hope this helps you. Follow me for faster replies. And smash that Thank you button.❤
