<span>p1=44/88=.50; p2=57/85=.67.
Under the null hypothesis of no difference, we pool the data to estimate the
common p of (44+57)/(88+85)=.584.
The test statistic is (.67-.50)/sqrt[(.584)(1-.584)(1/88 + 1/85)]=2.268 (which is stat sig. at a .095 level).</span>
Larger because I want the points and you are going to get an F
Well, it is a good and interesting question
Such areas could be calculated in a single shoot and also by dividing the whole shape into other shapes and the total area would be the sum of these areas
I prefer the way of a single shoot ...
The figure represents a trapezoid:
its lower base = 21 units
its upper base = 12 units
the normal height between them = 8 units
NOW
The area of a trapezoid = [(sum of bases' lengths) ÷ 2] * height
= [(12 + 21) ÷ 2] * 8 = 132 sq units
Hope that helps
Answer: b
Step-by-step explanation: There was the same question on brainly and they said that the submarine sandwich one was right.
Answer:
= 10 - 3n
Step-by-step explanation:
the terms 7, 4, 1, - 2 form an arithmetic sequence with n th term
= 
+ (n - 1)d
where d is the common difference and the first term
here d = - 2 - 1 = 1 - 4 = 4 - 7 = - 3 and = 7, hence
= 7 - 3(n - 1) = 7 - 3n + 3 = 10 - 3n
