Given triangles are similar, so we setup a proportion
(140-x)/81 = x/9
solving gives x = 14
AC = 140-x = 140-14 = 126
(5+5)²-17-3
(25)²-17-3
625-17-3
605
Answer:
To find the x-intercept, substitute in 00 for yy and solve for x. To find the y-intercept, substitute in 00 for x and solve for y.
x-intercept(s): (−6,0)(-6,0)
y-intercept(s): (0,21)
According to the given expected value, it is found that Marcos' statement is correct.
-
The interpretation of the <em>expected value</em> is that <u>over a large number of trials, the average value will be close to the expected value</u>.
In this problem:
- The expected value is of $25.
- Hence, if many of the plans are sold, the average profit per plan will be of $25, and Marcos' statement is correct.
About Amaya's statement, among groups of 1,000 customers there can be variations, hence, she is incorrect.
