Answer:
<span>112</span> or 1 to 12
Explanation:
The ratio is
<span><span><span>23</span>8</span>=<span>2<span>3⋅8</span></span>=<span>224</span>= 1/12</span>
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:
2x+10
Step-by-step explanation:
x is gorans age
Gabriela has a stack of 9 nickels.
0.72 x 9 = 0.08
12 - x = 5
Subtract 12 from both sides
12 - 12 - x = 5 - 12
- x = - 7
Divide both sides by -1
-x/-1 = -12/-1
x = 7
