that is right correct answer
r = radius
Arc length = 2(3.14)r
7.9 cm = r
Plug our values in
Arc length = 2(3.14)(7.9 cm)
Arc length = 49.6 cm
Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)
To get the probability of less than 109.1 cm, the solution is computed by:
z (109.1) = (X-mean)/standard dev
= 109.1 – 108/ 0.6
= 1.1/0.6
=1.83333, look this up in the z table.
P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%
Answer: 7 is in tens place
Step-by-step explanation: 8928 ÷ 24 = 372
Ones place - 2
Tens place - 7
Hundreds place - 3
The 7 is in the tens place
Just assuming - A = 20, B = 120, and C = 40
F = 30, G = 75, and H = 75
