Answer:
Step-by-step explanation:
a=3, b=-15, c=20
Discriminant can be calculated as
The roots are imaginary
The solution is
The roots are not real i.e these are imaginary
a=3, b=5, c=-8
Discriminant can be calculated as
The roots are real
By quadratic formula method
The solution is
which are required roots.
I choose this method because I can get the solutions directly by substituting the values in formula, and I don't have to guess the possible solutions.
Answer:
The correct option is A
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is
Generally the the probability that a randomly selected zucchini will weigh between 0 55 pound and 13 pounds is mathematically represented as
=>
So looking the option of normal curves given in the question we see that it is option A that matches our interval
Answer:
Step-by-step explanation:
1/4x-18=-22
+18 +18
1/4x=-4
*4 *4
x=-16
Well to do this you would have to find the LCM (least common multiple) of 4 and 3. so, if you line up all of the multiples of 4
4,8,12,16,20,24,28,32,36,40....
and the multiples of 3
3,6,9,12,15,18,21,24,27,30,33....
the least multiple that they both have is 12
Step-by-step explanation:
Step-by-step explanation:
Given the table:
Month f(x) = Number of imports g(x) = Number of exports
January (1) 3 1
February (2) 4 3
March (3) 5 5
April (4) 6 7
From the table, it is clear that:
Number of imports = number of month + 2
so
also
Number of exports = 2(number of month) + 1
so
Therefore, the number of imports equals the number of months plus one. i.e., which is a linear function.
If we compare it with the slope-intercept form of the line
Then,
slope = m = 1
y-intercept = 2
Also number of exports equals is also a linear function.
i.e.
Here,
slope = m = 2
y-intercept = -1
