12-(x+3)=10
Simplify the equation.
12-x-3=10
Combine like terms.
(12-3)-x=10
Simplify.
9-x=10
Subtract 9 from both sides to get x by itself.
-x=1
Divide both sides by -1 to get x by itself.
x=-1

The insurance Gil has is most likely individual life insurance.
Answer:
a) The probability of obtaining a sample mean that is less than or equal to 1770 hours is P(M≤1770)=0.0013.
b) It is unusual, as there are only 13 chances in 10,000 (0.13%) of having this outcome.
Step-by-step explanation:
We have a population lifetime with mean of 1800 hours and standard deviation of 100 hours.
Samples of size n=100 are taken and tested.
We can calculate the probability of obtaining a sample mean that is less than or equal to 1770 hours using a z-score for the sample Mean M=1770 and then calculating its probability according to the standard normal distribution:
Answer:
1. G IS A DEPENDENT VARIABLE
2.U IS THE INDEPENDENT VARIABLE
Step-by-step explanation:
G is a dependent variable because its values will rely on the values of U multiplied by 748. A dependent variable in most cases is isolated on one side of an equation ( mostly the left-hand side) and it value is affected by the values selected on the other side of the equation.
U is an independent variable because it stands on its own such that it does not rely on the behavior of another variable to determine its value/characteristic.Characteristic here i mean , U is freely selected without considering the behavior of other variable, thus it does not face any restrictions as compared to G.
