<span>σ</span> is a symbol for summation that means that it is used to add all the vales of the equation in the range
for example taking 0<x<4 and x is an integer
so Ď(x - 2)^2= (1-2)^2+(2-2)^2+(3-2)^2
The options were
a. Square each value
b. Subtract 2 points from each score
C. Sum the squared values
d. Subtract 22 from each X2 value
As we can see above the answer is C. Sum the squared values
Step-by-step explanation:
b can be used to check her score
Answer:
441 miles
Step-by-step explanation:
Write and solve an inquality to answer this question:
($24.95/day)(2 days) + ($0.34/mile)x ≤ $200
The first term becomes $49.30; the second term $0.34x; their sum must be ≤ $200.
More concisely, 49.30 + 0.34x ≤ 200.
Isolate x by subtracting 49.30 from both sides:
0.34x ≤ 150.10.
Divide both sides by 0.34:
x ≤ 150.10/0.34, or 441.47 miles. You must round this off to the nearest whole mile, which would be 441 miles.
