Answer:
x = -3 and x = 1/2
Step-by-step explanation:
To find the solutions to
2x² + 5x - 3 = 0
we can use the quadratic formula, as follows:
Answer:
6.27
Step-by-step explanation:
We are to obtain the standard deviation of the given values :
{24, 18, 31,25, 34}
The standard deviation = √(Σ(x - mean)²/ n)
The mean = (ΣX) /n
Using calculator to save computation time :
The standard deviation, s = 6.27 (2 decimal places)
The values coming in the interval (-3,1] are -2, -1, 0, and 1.
<h3>What is defined as the term interval notations?</h3>
- An interval is represented on a number line using interval notation. In all other sayings, it is a method of writing real number line subsets.
- An interval is made up of numbers that fall between two specific data set.
- Intervals can be categorized according to the numbers in the set.
- Interval Open: The endpoints of a inequality are not included in this type of interval.
- Interval Closure; The endpoints of a inequality are included in this type of interval.
- Interval with Half-Open Doors: This interval contains only one of inequality's endpoints.
The given interval notation is;
(-3,1], it is the case of half open half close.
-3 comes with the open interval, it means its value will not be included in the interval.
1 is with the closed interval, it means its value will be included in the interval.
Thus, the values lying between the interval (-3, 1] are -2, -1, 0, and 1.
