The equation we'll use for this is:Total Gifts = Veronica's Gifts (v) + Natalie's Gifts (n).
12 = v + n
The problem says Veronica got 3 times as many gifts as Natalie.
You can directly translate this into an equation!
v = 3 * n = 3n. This means we can replace any v with 3n.
So, 12 = v + n = 3n + n = 4n
12 = 4n
3 = n. Natalie got 3 gifts.
We can now plug back in for Veronica's gifts:
v = 3n
v = 3(3)
v = 9. Veronica got 9 gifts.
Answer:
9
Step-by-step explanation:
x = first number
3x = second number
2x = third number
27 = x + 3x+ 2x
27 = 6x
x=4.5 (first number)
3(4.5) = 13.5 (second number)
2(4.5) = 9 (third number)
(4.5 + 13.5 + 9) /3 = 9
Wow after doing all that I realized that all you had to do was 27/3 since there's 3 numbers.
We can start out simple, so here's some:
If you ever drew a sea saw as a child, or seen it, you probably had seen a part that looks like a triangular prism. It's somewhere in the structure.
Many building infrastructures have them. The roofs of many houses are pointed in some what of a triangle like shape so that rain water can roll off of them easier.
Hope these two help or at least spark some ideas!

Answer:
At a level of 95%, it is expected that the interval [0.45; 11.59] contains the value of the ductility in steel when its carbon content is 0.5%.
Step-by-step explanation:
Hello!
Considering the dependent variable:
Y: Ductility in steel.
And the independent variable:
X: Carbon content of the steel.
The linear regression was estimated and a prediction interval was calculated.
The prediction interval is calculated to predict a value that the variable Y (response variable) can take for a given value of the variable X (predictor variable) in the definition range of the linear regression line. Symbolically [Y/X=
]
In this case 95% prediction interval for Y/X=0.5
At a level of 95%, it is expected that the interval [0.45; 11.59] contains the value of the ductility in steel when its carbon content is 0.5%.
I hope it helps!
