If you add the standard deviation to the average, it is 14.84. Because Marcus's score was lower than that, he will not receive a certificate.
I think this should be right for the reason and the calculation.

2. 80 mm

Step-by-step explanation:
Do them all by the butterfly method.
Answer:
![f(x)=-x^{2} +8x-16](https://tex.z-dn.net/?f=f%28x%29%3D-x%5E%7B2%7D%20%2B8x-16)
Step-by-step explanation:
we know that
A polynomial function that has a leading coefficient of -1 and root 4 with multiplicity 2 is equal to
![f(x)=-(x-4)^{2}](https://tex.z-dn.net/?f=f%28x%29%3D-%28x-4%29%5E%7B2%7D)
Expand the function
![f(x)=-(x^{2}-8x+16)\\ \\f(x)=-x^{2} +8x-16](https://tex.z-dn.net/?f=f%28x%29%3D-%28x%5E%7B2%7D-8x%2B16%29%5C%5C%20%5C%5Cf%28x%29%3D-x%5E%7B2%7D%20%2B8x-16)
a^2=b^2+c^2
×=11; a^2=(6×11+7)^2+(3×11)^2
a^2=6418
so the length is estimately 80.11
Answer:
= 570
Step-by-step explanation:
Priority in order:
- Bracket
- X and /
- + and -
(50 x 40 / 4 + 20) + (50 / 2 + 25)
= (2000 / 4 + 20) + ( 25 + 25)
= ( 500 + 20) + ( 50 )
= ( 520 ) + 50
= 520 + 50
= 570
