The height of the blue spruce was 45.
We find the mean by adding all of the data points and dividing by the number of data points. We will add the unknown value x and change the number we're dividing by to 7:
(160+320+100+110+200+220+x)/7 = 165
(1110+x)/7 = 165
Multiply both sides by 7:
1110 + x = 1155
Subtract 1110 from both sides:
x = 45
Since the scale factor is smaller than one (the original), the resulting image is smaller than the original.
Hope this helped, and feel free to ask more questions if needed(:
Answer:
Bc = √63 ft
Step-by-step explanation:
Here, we want to get the length of BC
As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side
So we want to get the third leg which is BC
we can use the Pythagoras’ theorem here
And that states that the square of the hypotenuse equals the sum of the squares of the two other sides
let the missing length be x
12^2 = x^2 + 9^2
144 = x^2 + 81
x^2 = 144-81
x^2 = 63
x = √63 ft
Hi there!
For these two equations, we would be using PEMDAS...

Answer:
the 2nd option f(-4) = g(-4) and f(0) = g(0)
Step-by-step explanation:
the right answer was the same x and sampe y. it means in their intersection for both f(x) anad g(x)
so the correct answer is f(0) = g(0) and f(-4) = g(-4)
