Answer:
? = 26 in
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
?² = 24² + 10² = 576 + 100 = 676 ( take the square root of both sides )
? = = 26
Answer:
Approximate probability that is less than 2 = 0.1515
Step-by-step explanation:
Given -
Mean = 2.2
Standard deviation = 1.4
Sample size ( n ) = 52
Let be the mean of accidents per week at the intersection during one year (52 weeks) .
probability that is less than 2 =
=
Putting
= ( Using Z table )
= 0.1515
