<span>First step is find total height of all the figures expressed in feet:
Liem: 6 ft 2 inch = 6,167 ft
Eli: 5 ft 9 inch = 5,75 ft
Faith 6 ft
Simon: 5 ft 4 inch = 5,34 ft
To calculate the total height we need to know that 12 inches are 1 foot
6’2”+5’9”+6+5’4”= 22 ft 15 inch = 23 ft 3 inch
Another way is by adding decimal figurel:
6,167 + 5,75 + 6 + 5,34 = 23,25 feet
Then we know that 3 feet are 1 yard, so then total height is:
23,25 / 3 = 7,75 yards</span>
Answer:
a=1
Step-by-step explanation:
To make this easier, combine like terms first.
-5+2a=4a-4-3a
-5+2a=a-4
Then, add 5 on both sides.
-5+2a=a-4
<u>+5 +5</u>
2a=a+1
Now, subtract a on both sides.
2a=a+1
<u>-a -a</u>
a=1
Hope this helps you out!!!! Have an amazing day :3

Answer:
The probability of no correct answers is 0.125 = 12.5%.
Step-by-step explanation:
For each question, there are only two possible outcomes. Either it is answered correctly, or it is not. The probability of a question being answered correctly is independent of any other question, which means that 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.
3 trials, each with probability of success (correct) given by p=0.50.
This means that 
The probability of no correct answers is
This is P(X = 0).


The probability of no correct answers is 0.125 = 12.5%.
