Answer: a. 0.04
Step-by-step explanation:
Given : Number of multiple choice questions = 2
Choices given in each question = 5
Since only one choice is correct out of 5.
So, the probability of selecting the correct answer =
Also, both questions are independent of each other.
It means , The probability of answering the two multiple choice questions correctly if random guesses are made
=( Probability of selecting the correct answer in question 1 ) x ( Probability of selecting the correct answer in question 2 )
=
Hence, the required probability =0.04
Answer:
62
Step-by-step explanation:
SA=2(5x2)+2(5x3)+2(3x2)
SA=20+30+12
SA=62
There are 12 inches in a foot
108/12 = 9
108 inches = 9 feet
Answer:
44.44°
Step-by-step explanation:
A tower that is 101 feet tall casts a shadow 103 feet long. Find the angle of elevation of the sun to the nearest degree.
We solve this question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = ?
Opposite = Height of the tower = 101 feet
Adjacent = Length of the shadow = 103 feet
Hence
tan θ = 101/103
θ = arc tan (101/103
θ = arctan(0.9805825242718447)
θ = 44.438294667°
Approximately to the nearest degree = Angle of elevation = 44.44°
Answer:
Step-by-step explanation:
The measurements given on the all American adults could produce a bias as it is supposed that this study aims at focusing on Education and religion in all American adults. This adults comprises of all the above mentioned religions among others.
Thus taking measurements on all american adults again among the other religions will produce a bias as among these percent, there would be individuals that belong to any of those religions producing a bias in the survey.
