Answer:

The given value is a statistic.      

Step-by-step explanation:

We are given the following information in the question:

"A health and fitness club surveys 40 randomly selected members and found that the average weight of those questioned is 157 lb"

Statistic:

  • A statistic is a numeric value that describes a sample.

Parameter:

  • A parameter is a value that describes the population.

Since, 157 lb is average weight of 40 randomly selected members which is a sample, thus, the given value here is a statistic describing a sample.

Which of the following are solutions to the equation below?<br><br> x^2-2x-24-0
Dominik [7]

Answer:

x=-4

x=6

Step-by-step explanation:

Lets put to work the well known quadratic equation:

x=\frac{-b+/- \sqrt{b^{2}-4ac } }{2a}

Let us also, remember the given equation: x^2-2x-24=0

Where 'a' would be equals to 1, 'b' equals to -2 and c equals to -24.

The quadratic equations with those values is:

\frac{2 +/- \sqrt{4+96} }{2}

Where we obtain two values.

x1= -4

and x2= 6

What is the value of m in the equation <img src="https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D" id="TexFormula1" title="\frac{1}
Novosadov [1.4K]

Answer:

The value of m is 44

Step-by-step explanation:

We have given:

1/2 m - 3/4 n = 16

Put the value of n in the given equation

1/2m - 3/4(8)=16

Now 4 and 8 will be canceled out by the table of 4

1/2 m - 3(2)=16

1/2m - 6 = 16

Now take the L.C.M of the denominator and solve for numerator:

m-2(6)/2 = 16

m-12/2 = 16

m-12 = 16*2

m-12 = 32

Add 12 at both sides:

m-12+12 = 32+12

m= 32+12

m=44

The value of m is 44....
