Answer:
Below.
Step-by-step explanation:
If we let the two numbers be x and y we could have the following equations:
xy = 112
y = 3x + 4.
Then if we want to find the value of x, from the first equation we get
y = 112/x, which we substitute in the second equation;
112/x = 3x + 4.
If you asking for a random one then heres a rand om one: Y^3–2 or y^4+7
Answer:
Variance σ² having standard deviation 2.5 is 6.25.
Step-by-step explanation:
The standard deviation is basically the square root of the variance.
So, if want to find the variance of the data we simply take square of standard deviation to get the variance of data.
standard deviation = σ = 2.5
taking square on both sides
(σ)² = (2.5)²
σ² = 6.25
So, variance σ² having standard deviation 2.5 is 6.25.
