Answer:
mean= 50
median = 40
mode 95
Step-by-step explanation:
Put the numbers in order from smallest to largest
7,12,13,40,88,95,95
The mean is adding up all the numbers and dividing by the number of numbers
(7+12+13+40+88+95+95)/7
350/7 = 50
The median is the middle number
7/2 = 3.5
Round up so the 4th number is the median
40 is the median
The mode is the most often which is 95 since is appears twice
Answer:
A
Step-by-step explanation:
Given 2 secants from a point outside the circle.
Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is
(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)
(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides
x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides
4x + 12 = 20 ( subtract 12 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2 → A
Answer:
Step-by-step explanation:
The y-intercept (when x = 0) on the quadratic graph is 3, the upper quadratic graph does not intersect the x-axis, and the endpoint of the function has an open circle that stops at x = 1. The starting point extends to the boundaries of the graph
Therefore, the piecewise function shown in the quadratic graph is given as follows;
f(x) = x² + 3; x < 1
The straight line graph has a negative slope and starts at x = 1, with a closed circle, extending to higher values of <em>x</em> to the boundaries of the graph
Two points on the straight line graph are (1, 3) and (5, -5), therefore, the slope is (-5 - 3)/(5 - 1) = -2
The equation of the function is y - 3 = -2·(x - 1)
∴ y = f(x) -2·x + 2 + 3 = -2·x + 5
f(x) = -2·x + 5; x ≥ 1
Answer:
C is the answer
g(x) = x² - 10 x + 29
Step-by-step explanation:
g(x) = (x -5)² + 4
= x² - 10 x +25 +4
= x² - 10 x + 29
∴ g(x) = x² - 10 x + 29
