Answer:
Do the parentheses first. then the operations. Then solve
Step-by-step explanation:
ABC = 180-120=60
ACB = 180-(40+60)=80
Therefore ECD= 80 as ACB and ECD are vertically opposite angles
the solution is A as that is where the graphs intersect each other
Answer:
The answer is 22 1/2-18 3/7. first we need to get a common denominator for the fractions. I will do 14. Now we have 22 7/14-18 6/14=4 1/14 ez
Step-by-step explanation:
Using the binomial distribution, there is a 0.3474 = 34.74% probability of getting one wrong number.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
For this problem, the values of the parameters are given by:
p = 0.15, n = 10.
The probability of getting one wrong number is P(X = 1), hence:

P(X = 1) = C(10,1) x (0.15)¹ x (0.85)^9 = 0.3474
0.3474 = 34.74% probability of getting one wrong number.

Answer:
O x >9
The arrow points left
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<em>Given 2 < x-7</em>
<em>adding '7' on both sides, we get</em>
<em>⇒ 2 + 7 < x -7 +7</em>
<em>⇒ 9 < x</em>
<em>⇒ x>9</em>
<em>Given inequality 2 < x -7</em>
The arrow points left
<u><em>Final answer</em></u>:-
solution is x >9
The arrow points left
