454.90, the 5 makes the 9 go up which in turn makes the 8 also go up.
Answer:
y = x -7
Step-by-step explanation:
y2 - y1 / x2 - x1
-5 - (-2) / 2 - 5
-3/-3
1
y = x + b
-2 = 5 + b
-7 = b
y = -7
y = x -7
Answer:
y = (√x)/13 for x > 0
Step-by-step explanation:
Actually, this is f(x) = 169x^2; the " ^ " indicates exponentiation. The graph consists of the right-hand half of the parabola 169x^2. Before we attempt to find the inverse function, we determine whether or not this function passes the vertical line test. If x is restricted to (0, infinity), a horizontal line intersects this graph only once. Therefore, this function has an inverse.
1. Replace 'f(x)' with 'y:' y = 169x^2
2. Interchange x and y: x = 169y^2
3. Solve for y: y^2 = x/169, or y = (√x)/13 for x > 0
Y is the amount of food that a manatee eats each day:
the weight is X
12% or its weight is X x 12 /100= 12x /100=3x/25
so the equation is y= 3x/25
the dependent variable is y (it depends to the value of x)
and the independent is x
range is 31.5, variance is 161.3 and standard deviation is 12.7 for a sample of top 10 annual TV personalities.
Step-by-step explanation:
- Average is mid-point is the mid-point of the data but can skew....
- On the Left or Right is there are higher or lower values.
- Range is difference between maximum and minimum value of data.
- Variance, measure of variability of data but squared or mean deviation.
- Standard deviation is the most important variability.
- It helps in finding out variability with 3 sigma deviations.
- Standard deviation is square root of variance and each sigma explains...
- The data lieing between or within the extreme values.
