Answer with explanation:</h2>
Given : A random sample of five Galaxy 8 smartphones is selected from the production line after final assembly, and the result of the weight control measurement is (in grams) are :
X= 155.1, 154.8, 155.5, 155.3, and 154.6.
here, n=5
The average weight :
∴ Average weight (
)=155.06 grams
Uncertainty = Standard deviation: 
i.e. Its uncertainty : 
The fractional uncertainty = 
69 of the coins are not nickels.
So if the main question is 9q x 3 it would equal 27q
Answer: x=−9/4
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(x+14)+1=5
Step 1: Simplify both sides of the equation.
−2(x+14)+1=5(−2)(x)+(−2)(14)+1=5(Distribute)−2x+

Answer: OPTION B
Step-by-step explanation:
First it is importanty definition, a relation is a function if and only if each input value has one and only one output value.
The input values are the x-values and the output values are the y-values.
Therefore, "y" is the Dependend variable and "x" is the Independent variable.
Knowing the above, you can understand the definition of "Domain" and "Range".
The Domain is defined as the set of all the possible values of "x" or the Independent variable
The Range is defined as the set of all the possible values of "y" or the Dependent variable.
Therefore, you can conclude that the correct answer is the given in the Option B.
