Answer:
x = 12
Step-by-step explanation:
The triangles are similar so we can use ratios
4x+12 32
------- = ------------
15 8
Using cross products
(4x+12) *8 = 15 * 32
(4x+12) *8 = 480
Divide each side by 8
(4x+12) *8/8 = 480/8
4x+12 = 60
Subtract 12 from each side
4x+12 -12 = 60-12
4x = 48
Divide by 4
4x/4 = 48/4
x = 12
Answer:
y = -5x + 6
Step-by-step explanation:
General equation of a line : y = mx + c......where c is intercept
To find m pick any two points..
(-2, 16) and (-1, 11)
Using (y - y¹) / (x - x¹)
(11 - 16) / (-1 - [-2]) = -5 / 1
= -5
To find c sub with any point for (x, y) and m
using (2, -4)
y = mx + c
-4 = -5(2) + c
-4 = -10 + c
6 = c
Input the values of m and c in the general equation without x and y
; y = -5x + 6
Answer:
D: A prediction based on data is reliable, because the means of the samples are close together.

<em>The question has inconsistent or incomplete data, so I'm filling the holes with key data.</em>
Answer:
<em>Every people at dinner received one-tenth of the original turkey= 0.1</em>
Step-by-step explanation:
<u>Proportions</u>
If some fraction a/b of a whole total M is to be computed and later removed, we proceed as follows
* Compute the portion to be removed as a/b*M
* Subtract it from the total quantity: M-a/b*M=M(1-a/b)
I'm assuming 1/5 of the turkey was lost due to overcooking. It means that (1-1/5) of the turkey remained for dinner, that is, 4/5 of the turkey.
Each people at dinner received the same amount of the remaining, so we must divide 4/5 by 8, to get 4/40, or 1/10. It means that every people at dinner received one-tenth of the original turkey
