Step-by-step explanation:
Given parameters
Percentage of all teachers the works in summer = 85%
Number of teachers sampled = 6 teachers
Unknown:
The probability that they all work in summer = ?
Solution:
Now, to solve this problem, let us find the number of teachers that works in summer from the given size;
Number of teachers = 85% x 6 = 5.1;
Since it is not possible to have 5.1 people, the number of teachers will be 5
The probability =
Answer:
x = - 3 ± 3
Step-by-step explanation:
given the equation x² + 6x - 9 = 0
We can solve for x using the quadratic formula
x = ( - b ± ) / 2a
with a = 1, b = 6 and c = - 9
x = ( - 6 ± ) / 2
= ( - 6 ± ) / 2
= ( - 6 ± ) / 2
= ( - 6 ± 6 ) / 2
x = - 3 ± 3
Answer:
13 + 5x
Step-by-step explanation:
Step 1:
9 + 4 + x + 4x
Step 2:
13 + x + 4x
Answer:
13 + 5x
