Let the sum of the 10 numbers be x, then
x/ 10 = 1445
x = 1445 x 10 = 14450
New mean = (14450 + 1500)/11 = 15950/11 = 1450
23 / 50 = 0.46
0.46 converted to a percent is 46%
Hi there!
Evaluating f(x) at x = 9 means we must use the piecewise function where x = 9 is included.
f(x) = 12 includes 9 because a "≤" is inclusive of the interval. Thus:
f(9) = 12
Answer:
x° = 60
Step-by-step explanation:
Vertically opposite angles are congruent, thus
x° = 60
