A = 1/2(a+x)h solve for x
ankoles [38]

For this case we have the following equation:

A = \frac {1} {2} (a + x) * h

We must clear the variable "x":

We multiply by 2 on both sides of the equation:

2A = (a + x) * h

We divide by h on both sides of the equation:

\frac {2A} {h} = a + x

We subtract "a" on both sides of the equation:\frac {2A} {h} -a = x

Answer:x = \frac {2A} {h} -a

4-13 Students in a management science class have just re- ceived their grades on the first test. The instructor has provided inf
inessss [21]

Answer:

a) y = 0.74x + 18.99; b) 80; c) r = 0.92, r² = 0.85; r² tells us that 85% of the variance in the dependent variable, the final average, is predictable from the independent variable, the first test score.

Step-by-step explanation:

For part a,

We first plot the data using a graphing calculator.  We then run a linear regression on the data.

In the form y = ax + b, we get an a value that rounds to 0.74 and a b value that rounds to 18.99.  This gives us the equation

y = 0.74x + 18.99.

For part b,

To find the final average of a student who made an 83 on the first test, we substitute 83 in place of x in our regression equation:

y = 0.74(83) + 18.99

y = 61.42 + 18.99 = 80.41

Rounded to the nearest percent, this is 80.

For part c,

The value of r is 0.92.  This tells us that the line is a 92% fit for the data.

The value of r² is 0.85.  This is the coefficient of determination; it tells us how much of the dependent variable can be predicted from the independent variable.
