Add 3.5 to 14.9------------
Answer:
8^2-9^2/17(-7+6) = 1
Step-by-step explanation:
8^2-9^2/17(-7+6) = 64 - 81 / 17 * (-1)
= -17/ -17 = 1
Answer:
Probability that a student who passed the test did not complete the homework = 0.07
Step-by-step explanation:
Given:
Total number of students = 28
Number of students who passed the test = 18
Number of students who completed the assignment = 23
Number of students who passed the test and also completed the assignment = 16
To find: probability that a student who passed the test did not complete the homework
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favorable outcomes/total number of outcomes
Let A denotes the event that students passed the test and B denotes the event that students completed the assignment
P(A only) =
Here,
So,
Therefore,
probability that a student who passed the test did not complete the homework = 0.07
Because the square has similar lengths, the equation would be
(7x-2)(7x-2)
We can use FOIL to solve this:
The area is 49x^2 - 28x + 4 in^2.
The exponent is (1/15)(5), which leads to 1/3.
We now have x^(1/3), which is equivalent to the cube root of x.
