Answer:
1. Group A and B agree with each other.
2. Group A and C do not agree with each other.
Step-by-step explanation:
When we are analizing this problem, we will see what are the ranges of this measured times. Since we are taking into account the error we can see that :
- Group A varies from 7.34-0.05 to 7.34+0.05. So the limits are (7.29 ;7.39)
- Group B varies from 7.38-0.03 to 7.38+0.03. So the limits are (7.35; 7.41)
- Group C varies from 7.46-0.06 to 7.46+0.06. So the limits are (7.40; 7.52)
Question 1 is about the overlapping response in Group A and Group B. And yes, we have an overlap between 7.35 to 7.39. Among this times both group A and B are in agree with each other within the experimental uncertainty.
Question 2 is now referring to Group A and Group C. And no, there isn't any common time where both groups agree with each other.

Answer:
- B
- B
- a) f(3y-1) = 24y -17; b) f(-7/4) = -23
Step-by-step explanation:
1. Any mapping requiring segment lengths to be congruent will require a "rigid" transformation, some combination of rotation, reflection, and translation.
If the transformation is not one of those, then segment lengths may change. The transformation we usually study that is not a rigid transformation is <em>dilation</em>. It preserves angles and slopes, but not segment lengths.
Of the choices listed, only choice B does not involve congruent segments.
__
2. In line with the discussion above, the dilation will preserve the slope of KM so that it is the same as the slope of K'M'. This is described by choice B.
__
3.
a) Finish simplifying the equation already written.
f(3y -1) = 8(3y -1) -9 = 24y -8 -9
f(3y -1) = 24y -17
b) f(x) = -23
8x -9 = -23
8x = -14 . . . . . . add 9
x = -14/8 = -7/4 . . . . divide by 8, reduce the fraction
x = -7/4 = -1.75
Answer:
The cost for camping is 266 pounds
The cost for camping per night is 14 pounds
The cost for camping at the second campsite would be 114 pounds more than the first one.
Per night that is 6 pounds more if you needed that.
If a point is on the graph of the exponential equation then it should be true when you solve.
g(x) = (1/5)^x
y = (1/5)^x
1/125 = (1/5)^3
cbrt(1/125) = 1/5
.2 = 1/5
.2 = .2 YES
5 = (1/5)^-1
5 = 5 YES
1/25 = (1/5)^-2
-2root(1/25) = 1/5
5 = 1/5 NO
0 = (1/5)^1
0 = .2 NO
The correct answers are <em>A and B</em>.
