ans C) each additional t-shirt being printed will increase the total cost by$11
Answer:
the value is 36
Step-by-step explanation: so you add
10.5, 11, 11.5, 12, 12.5...this is an arithmetic sequence with a common difference of 0.5
an = a1 + (n - 1) * d
n = term to find = 23
a1 = first term = 10.5
d = common difference = 0.5
sub and solve
a(23) = 10.5 + (23 - 1) * 0.5
a(23) = 10.5 + 22 * 0.5
a(23) = 10.5 + 11
a(23) = 21.5 <===
Total area = 12 x 24.6 = 295.2
Area of circle = 3.14 x 3.6² = 40.69
Area of square = 4.2 x 4.2 = 17.64
Square and circle = 40.69 + 17.64 = 58.33
Probability = 58.33/295.2 = 0.1976
Rounded answer = 0.20
