Answer:
The costs will be the same at 21 pounds.
Step-by-step explanation:
Let p be the number of additional pounds. (Total weight would be p+1).
UPS cost = 7 + 0.20p
FedEx cost = 5 + 0.30p
We need these to be equal.
7 + 0.20p = 5 + 0.30p
0.10p = 2
p = 20
I think it’s -6 but I would check with someone else too lol
The <em><u>correct answer</u></em> is:
∠LOA ≅ ∠LMA
Explanation:
AAS, or angle-angle-side, states that if two angles and the non-included side of one triangle are congruent to the corresponding two angles and non-included side of a second triangle, then the triangles are congruent.
We have an angle and a side. Out of the remaining two angles, the ones that would make the side marked, LA, non-included are LOA and LMA. This must be the missing information.
Answer: It is usefull.
Step-by-step explanation:
The regression squared talks to us about how well the model fits in the experimental data, where 0.0 means that the model does not fit at all, and 100% means that the model fits perfectly.
This is always true? well, really not, there are cases where you can have a regression square of 0.98, which would imply that the model is correct, but when you see the residual vs fit the plot, you may see some pattern, which implies that there is a problem with the model (you always expect to see randomness when you look at this graph). While for a prediction, this actually may work (at least in the range of the data points, outside this range the model and the data may not coincide at all)
Now, it still is useful in a certain range, so we can actually conclude that if R^2 = 0.949 represents a model that is useful for predicting the exam marks.
Answer:
Option 3. (2π + 40) mm².
Step-by-step explanation:
Area of the composite figure = area of MKCD + area of ABCD + area of semi circle with AB as diameter.
Then Area A = (DC + MK)/2 × DN + AB² + (1/2)×π×2²
= (4 + 8)/2 × 4 + 4² + (1/2)×π×4
= 24 + 16 + 2π = (2π + 40) mm²
Therefore option 3. (2π + 40) mm².
