If you mean 46 * 3 = 138
If you mean 46 + 3 = 49
If you mean 46 - 3 = 43
If you mean<span> 46 ÷ 3 = 15.3
Hope it helped

Since the ground already has an elevation of 15 degrees, the ladder needs to
be set at 60 degrees to reach a height of 10 ft.
In order for a ladder to reach a height of 10 feet, the ladder needs to be
placed at 75 degrees angle to the ground. This is when the ground has no
angle of elevation or when it flat.
Now, if the ground has an angle of elevation of 15 degrees , the degrees in
angle the ladder needs to be set can be solved as follows:
<h3>Angles in degree: </h3>
Therefore, the ladder needs to set at an angle of 60 degrees if the
elevation of the ground is already 15 degree. The elevation of the ground
will complement the angle in degrees required for the ladder to reach 10
feet.

Answer:
The answer is exactly -2,299. But since this is a mental math question it's okay if it's not the exact answer. The answer would be "A"
Answer:
D. Find the cumulative probability for 8 in a binomial distribution with n = 20 and p = 0.5.
Step-by-step explanation:
For each question, there are only two possible outcomes. Either the student guesses the correct answer, or he does not. The probability of the student is guessing the answer of a question correctly is independent of other questions. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
20 questions
This means that
How would you find the probability that the student will get 8 or fewer answers correct?
That is, it is the same as the cumulative probability for 8.
So the correct answer is:
D. Find the cumulative probability for 8 in a binomial distribution with n = 20 and p = 0.5.
