Answer:
The overall group of sciences that study numbers, shapes and their relationships. An example of math is arithmetic, the study of addition, subtraction, multiplication and division.
The critical value is used to compute the margin of error. (Margin of error = Critical value x Standard deviation of the statistic or <span>Margin of error = Critical value x Standard error of the statistic).
If the statistic has normal sampling distribution, then the t</span><span>he critical value can be expressed as a </span>t score<span> or as a </span>z score<span>.
</span><span>α = 1 - (confidence level / 100)
</span><span>α = 1 - (93 / 100)=1-0.93=0.07
</span>The critical probability is: <span>pc= 1 - α/2 pc=1-0.035=0.965
The critical value is 1.81.</span>
X = 8, please mark me brainliest
The fact that the coefficients are pairwise identical (except for sign) tells you that x^2 -1 is a factor (and x-5 is the other factor). Of course, you recognize x^2-1 as a special form (the difference of squares) that is factored as (x +1)(x -1).
The zeros are x = -1, +1, +5.
