QUESTION → ![\frac{3}{2}x + 3 = 0](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7Dx%20%2B%203%20%3D%200)
Start by subtracting 3 from both sides to get
.
Now multiply both sides by the reciprocal of 3/2, which is 2/3.
On the left, we have x, and on the right, -3(2/3) is -2.
So we have x = -2.
Answer:
14 : 18, 14 to 18, 14/18
You can also use the reduced ratio.
7 : 9, 7 to 9, 7/9
Answer:
a. y = 27.5 - 0.3X
b. 20
Step-by-step explanation:
y = a + bX
usin the table in the attachment i added, we so for the regression equaion
n = 8
∑xy = 4460
∑x = 280
∑y = 136
∑x²= 10800
![b=\frac{8(4460)-(280)(136)}{8(10800)-280^{2} } \\b=\frac{35680-38080}{86400-78400} \\b=\frac{-2400}{8000} \\b = -0.3](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B8%284460%29-%28280%29%28136%29%7D%7B8%2810800%29-280%5E%7B2%7D%20%7D%20%5C%5Cb%3D%5Cfrac%7B35680-38080%7D%7B86400-78400%7D%20%5C%5Cb%3D%5Cfrac%7B-2400%7D%7B8000%7D%20%5C%5Cb%20%3D%20-0.3)
from here we solve for a
![a= \frac{136-(-0.3)(280)}{8} \\a =\frac{136+84}{8} \\a=\frac{220}{8} \\a = 27.5](https://tex.z-dn.net/?f=a%3D%20%5Cfrac%7B136-%28-0.3%29%28280%29%7D%7B8%7D%20%5C%5Ca%20%3D%5Cfrac%7B136%2B84%7D%7B8%7D%20%5C%5Ca%3D%5Cfrac%7B220%7D%7B8%7D%20%5C%5Ca%20%3D%2027.5)
a. the estimated regression equation
y = 27.5 - 0.3X
b. at x = 25
y = 27.5 - 0.3(25)
y = 20 is the number of defective parts.
Answer:
The answer is 3/8
Step-by-step explanation:
If you only have 3 paint gallons but 8 cans then each can will have to have less than one paint can in it. Since all the answers except for 3/8 are larger than one, 3/8 is the correct answer.
Congratulations you got it correct the answer is c
