Answer:
The options given in the question are incorrect , the correct options are:
a. - 1.645 b. -2.066 c. -2.000 d. -1.960
The test statistic to see whether the proportion is below the requirement is c. -2.000.
Step-by-step explanation:
p= 24/64 = .375
π0= .50
zcalc= (0.375 - 0.50)/[(0.50)(1 - 0.50)/64]
= -2.000
Answer:
<h3>Both are correct</h3>
Step-by-step explanation:
All the sides of an equilateral triangle are equal. Hence;
Perimeter of an equilateral triangle = 3S
S is one of the side length
Given;
S = 4n-2
Perimeter of the triangle = 3(4n-2)
This can also be expressed as P = S + S + S
P = (4n-2) + (4n-2) + (4n-2)
This shows that both methods are correct
Answer:
<b = 133
<c = 47
Step-by-step explanation:
<b and 133 are vertical angles and vertical angles are equal
<c and 133 form a straight line so they add to 180
<c+133 = 180
<c = 180-133
<c =47
L=2w+6
260=lw
Substitute for l
260=w(2w+6)
260= 2w^2+6w
2w^2+6w-260=0
2(w^2+3w-130)
2(w+13)(w-10)
w=-13, w=10
Since width cannot be negative it must be 10
260=l(10)
26=l
Final answer: length-26 ft, width-10ft
