Gabrielle is x years old.
Felicia is 6 years older.....so Felicia is x + 6
the mom is twice as old as felicia...so the mom is 2(x + 6)
the aunt is x years older then mom....so the aunt (tanya) is 2(x + 6) + x
so Tanya/s age is :
2(x + 6) + x =
2x + 12 + x =
13x + 12 <===
The shape that is generated is a Cone.
A triangle, when rotated about one of it's side will generate a solid in a form of a Cone. The cone could be a hollow one or a solid filled one, depending on the properties of the triangle being rotated.
Answer:
The standard deviation of X is 0.7
Step-by-step explanation:
We are given the following distribution:
x: 0 1 2 3
P(x): 0.3 0.5 0.2 0.4
We have to find the standard deviation of X.
Formula:
Thus, the standard deviation of X is 0.7
Slope = (-8 - 4)/(-4 -0) = -12/-4 = 3
y-intercept so b = 4
equation: y = 3x + 4
answer: <span>C. y = 3x + 4</span>
