G(x)=-(x^2-6x+5)
=-(x-6x+9-9+5)
=-(x-3)²+4
It is reflected across the a axis, shifted 3 units to the right, shifted 4 units up, and It has an axis of symmetry at x=3
Answer:
a) ![s= 9.74](https://tex.z-dn.net/?f=%20s%3D%209.74)
D. 9.74
b) ![Median= 74](https://tex.z-dn.net/?f=%20Median%3D%2074)
B. 74
Step-by-step explanation:
Part a
We have the following dataset given:
69 74 75 62 70 93 64 69 61 88 67 77 87 90 66 91 77 63 82 82 71 74 76 65 83
We can begin calculating the sample mean with the following formula:
![\bar X = \frac{\sum_{i=1}^n X_i}{n}](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%3D%20%5Cfrac%7B%5Csum_%7Bi%3D1%7D%5En%20X_i%7D%7Bn%7D)
And replacing we got:
![\bar X = 75.04](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%3D%2075.04)
Now we can calculate the sample deviation with the following formula:
![s =\sqrt{\frac{\sum_{i=1}^n (X_i-\bar X)^2}{n-1}}](https://tex.z-dn.net/?f=%20s%20%3D%5Csqrt%7B%5Cfrac%7B%5Csum_%7Bi%3D1%7D%5En%20%28X_i-%5Cbar%20X%29%5E2%7D%7Bn-1%7D%7D)
And after replace we got:
![s= 9.74](https://tex.z-dn.net/?f=%20s%3D%209.74)
Part b
For this case we need to sort the value on increasing way:
[1] 61 62 63 64 65 66 67 69 69 70 71 74 74 75 76 77 77 82 82 83 87 88 90 91 93
And the median would be the value in the position 13 and we got:
![Median= 74](https://tex.z-dn.net/?f=%20Median%3D%2074)
Answer:
I think the answer would be
Alloy A 30%
Alloy B 40%
The reason I say that is because Alloy B has a higher amount of pure silver so yeah
I hope this helps mark me brainliest and tell me if I'm wrong please so Then I could fix it.
P.S. Wegnerkolmp2741o is gonna answer so I would go with his
The relationship between 1’s in the value of 911, 147, 835
shows their numerical order in the number. In which to further elaborate we
shall break down the number into its expanded form and word form:
<span><span>1. </span>900, 000,
000 = nine hundred million</span>
10, 000, 000 = ten million
1, 000, 000 = one million
100, 000 = one hundred thousand
40, 000 = forty thousand
7, 000 = seven thousand
800 = eight hundred
30 = thirty
5 = five
<span><span>2. </span><span> Nine hundred eleven million one hundred
forty-seven thousand eight hundred and thirty five. </span></span>

22.5
