The formula for calculating the annual insurance is D. p= 2rb
Answer:
Any equation shown in the explanation
Step-by-step explanation:
Hello!
Combining like terms means combining terms with the same variables.
So combing all x's, all y's, all numbers, etc.
2/3x - 9 - 2x + 2 = 1
combine the x's
-1 1/3 x - 9 + 2 = 1
combine normal numbers
-1 1/3 x - 7 = 1
Add 7 to both sides
-1 1/3x = 8
Make mixed number into improper fraction
-4/3x = 8
Multiply both sides by 3
-4x = 24
Divide both sides by -4
x = -6
The answer would be any of the equation I showed above
Hope this helps!

Step-by-step explanation:
Answer:
0.2839 = 28.93%
Step-by-step explanation:
In order to find find the probability that one car chosen at random will have less than 68.5 tons of coal, we have to find z
Le x be tons of coal in a car
Z = (x – mean)/standard deviation
Z = (x – μ)/ σ
P (x<68.5) = P(z < (68.5-69)/0.9)
P (x<68.5) = P(z < -0.5555)
Then we use the z table to find the area under the curve.
P (x<68.5) = 0.2893
