A.) Here, w = 550kg/m^3.
Therefore, S = (0.032(550) - 2.5)/10000 = 0.00151
After drying, the beam will be (1 - 0.00151) x 12.027 = 12.009
b.) 0.0012 = (0.032w - 2.5)/10000
0.032w - 2.5 = 12
0.032w = 12 + 2.5 = 14.5
w = 14.5/0.032 = 453 kg/m^3
Therefore, the required water content is 453 kg/m^3
Answer:
False
Step-by-step explanation:
It is a linear equasion because it's in ax+by=c form
Answer:
x=83
Step-by-step explanation:
The sum of interior angles in a triangle will always be equal to 180 degrees. Knowing this, we can set up the following equation:
35+62+x=180
97+x=180
Subtract both sides by 97
97+x-97=180-97
x=83
I hope this helps!
It is 24 because 5t=5xt and t is 2 then 2m= 2xm m=7 so 24
Answer:
The probability that in a one-game playoff, her score is more than 227 is 0.4404.
Step-by-step explanation:
We are given that Susan has been on a bowling team for 14 years. After examining all of her scores over that period of time, she finds that they follow a normal distribution. Her average score is 225, with a standard deviation of 13.
<em>Let, X = scores over that period of time</em>
X ~ N(
)
The z score probability distribution is given by;
Z =
~ N(0,1)
where,
= average score
= standard deviation
So, probability that in a one-game playoff, her score is more than 227 is given by = P(X > 227)
P(X > 227) = P(
<
) = P(Z > 0.15) = 1 - P(Z
0.15)
= 1 - 0.55962 = 0.4404
Therefore, probability that in a one-game playoff, her score is more than 227 is 0.4404.
