The correct answer for the question that is being presented above is this one: "C) 1.6." Hank is painting his grandfather's fence. He painted 40 linear feet in 85 minutes. He still has 360 linear feet to paint. His cousins, Sam and Alex, come <span>to help. Sam paints twice as fast and Alex paints half as fast as Hank. The constant of proportionality that relates the current fence painting rate is 1.6.</span>
2(n + 5) = -2
First, our goal to this problem is to get the variable (n) and an unknown number on each side. To start off, we can divide both sides by 2.

Second, we can go ahead and cancel 2 out, which will replace it with a -1.

Third, our next step will to be to subtract 5 from each side.

Fourth, our last step is to simplify -1 - 5. This is quite simple. -1 - 5 = -6, so -6 is what the variable (n) equals.

Answer:
0.5244 is the answer.
Step-by-step explanation:
Given that the mean weight of males adult is 165 pounds.
Std deviation is 30 pounds
Sample size n = 35
Hence sample std deviation = 30/sq rt 35 = 5.071
Then X bar the mean of the sample follows a normal distribution
X bar : N(165, 5.071) by central limit theorem
Required probability =P(X<155)
When x =155, Z = 
Hence P(X<155) = P(Z<-1.972) = 0.5-0.4756
= 0.5244
Answer:
This is the associative property.
Step-by-step explanation:
The only operation in this expression is multiplication.
We know that the order in which we multiply numbers does not change their product; therefore we can group different numbers together and get the same product.
In this case, on the right hand side, 3 and 4 are grouped together first, then multiplied by 6. This gives us 12*6 = 72.
On the left hand side, 4 and 6 are grouped together first, then multiplied by 3. This gives us 24*3 = 72.
