I think the answer is 6 but I might not be right. Please don’t be mad if it’s wrong. :(
Answer:
5=3+2
7=5+2
9=7+2
so this is 3,5,7,9
Step-by-step explanation:
The % margin of error means that the real value is in the range between the mean less the margin error and the mean plus the margin error. This is [ mean - % of error, mean + % of error]. Then, in this case the error of +/- 2% means that the expected population proportion that wants flexible working hours is between 60% - 2% and 60% + 2%, which is<span> between 58% and 62%. </span>

Answer:
Step-by-step explanation:
Look at the top triangle.
It is an isosceles triangle because two of the sides are marked equal.
The angles opposite the congruent sides are called base angles. (in the case x and z)
Base angles of an isosceles triangle are equal.
In addition, we use the Triangle angle sum theorem - the sum of the angles in a triangle is 180 degrees
60 + x + y = 180
x+z =120
but x = z so by substitution
x +x = 120
2x = 120
x = 60
z = 60
likewise for the bottom triangle:
50 +50 + Y = 180
Y = 80
