Given mean μ = 7.6 and standard deviation σ =3.1
The z score value for x= 5 is given by
Z = 
Z = 
Z = -0.8387
The Z- score value rounded to nearest tenth is -0.8
The correct answer choice is A. -0.8
x = -3/4
(x equals negative three over four)
Answer:
L = 5S - 3
length of long side = 134.5 ft
length of short side = 27.5 ft
Step-by-step explanation:
L = 5S - 3
2L + 2S = 324 (keyword: enclose)
2(5S - 3) + 2S = 324
10S - 6 + 2S = 324
12S = 324 + 6 = 330
Thus S = 330/12 = 27.5 ft
Thus L = 5(27.5) - 3 = 134.5 ft
Two or more points are said to be collinear if they lie on the same straight line.
Given a straight line XY, with a point P on the straight line between point X and Y, then
XP + PY = XY
From the question, it was given that AB = 7 and BC = 4, so if A, B, C are colinear, then
AB + BC = AC
i.e. 7 + 4 = 11
But, from the equation, AC = 9.
Therefore, points A, B and C are not collinear.
