Answer:
9.784
Step-by-step explanation:
remember this formula for right triangles (a^2+b^2=c^2)
so 7.4^2+6.4^2=c^2
54.76+40.96=c^2
95.72=c^2
this is where we do this
square root of 95.72 is around 9.784
Subtract 8.263 from 13.48

Answer:
So then the best option would be:
a. 1/25
Step-by-step explanation:
For this case we assume that the sample space for the numbers is :
And the sample space for the numbers is:
Both sampling spaces with a size of 5.
We define the following events:
A="We select a 2 from the numbers"
B= "We select a E from the letters"
We can find the individual probabilities for each event like this:
And assuming independence we can find the probability required like this:
The last probability is the probability of obtain obtain a 2 AND an E
So then the best option would be:
a. 1/25
