14 since Leah had 7 inches of ribbon and is cut but 1/2 so you multiply the 7 by 2
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>
Look at the cube root of each term...
-1000^(1/3)=-10
p^12^(1/3)=p^4
q^3^(1/3)=q
So
-10p^4q

I calculated it logically
Answer:
Trevor has 16 number of shirts
Step-by-step explanation:
We have been given that Trevor and Marisa together have 28 t shirts to sell if Marissa has 4 fewer t shirts than Trevor
let the number of shirts Trevor have be x
And since, Marissa has 4 fewer than Trevor so number of shirts Marissa will have be x-4
Hence, according to question equation becomes:
x+x-4=28
We will solve for x to find the number of t shirts Trevor has
2x -4 =28
2x = 32
x =16
Hence, Trevor has 16 number of shirts
