Answer:
Um I think it is 120%, but i am not totalyy sure
X - 4/2 ; where x = -1.6
Substitute x by its value.
-1.6 - 4/2 *as you notice, one number is in decimal and the other is in fraction form. We need to convert one form to the other to make the numbers like numbers so that solving the equation will be easier and less confusing.
4/2 can easily be converted into decimal by dividing 4 by 2 which equals to 2.
So, -1.6 - 2 = ? The operation is a subtraction, but the other number is in negative form, if both numbers have the same sign, we add them up and the sign is carried over to the sum.
-1.6 -2 = -3.6 * we add 1.6 + 2 = 3.6, then we carry over its negative sign = -3.6
The average of the first three is 83 (85 + 90 + 74)/3
The average of the next 3 is 86.
The difference is 3
Answer:

Step-by-step explanation:
Notice how each congruent square is divided into four equal parts. Since each square has four parts and there are four squares, there are
of these parts in total. Because each of these parts make up
of each square, all parts are equal. Therefore, you can count the total number of shaded parts to get your percentage.
The top left and bottom right both have one part shaded each for a total of
parts.
The top right and bottom left have
and
parts shaded, respectively, for a total of
parts.
Therefore, in total, there are
parts shaded out of
total parts.
Thus, the percentage of the total area that is shaded is:
.
Using it's concept, it is found that there is a 0.3043 = 30.43% probability of at least one O-ring failing.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, of the 23 flights, 7 had at least one failure, hence the probability is given by:
p = 7/23 = 0.3043.
