The system of linear equations that may be used in order to solve this problem is as follows:

x + y = 37
2x + 3y = 95

This is considering that x is the number of bracelets sold and y is the number of necklaces.

The values of x and y in the equation are 16 and 31, respectively.

Thus, the answer is 16 bracelets and 21 necklaces.

Answer:

The null hypothesis is  H_o :  \beta_1 = 0

 The alternative hypothesis is  H_1 :  \beta_1 \ne 1

Step-by-step explanation:

From the question we are told that

        The number observations is  n =  100

         The  annual salary (in dollars) is  y

          The  mean score on teaching evaluation is  x

          The the relationship between the y and  x is

                y =  \beta_0  +  \beta _1 x + \epsilon

Where  \beta _1 is the mean of the equation so

  The null hypothesis is  H_o :  \beta_1 = 0

   The alternative hypothesis is  H_1 :  \beta_1 \ne 1

Cross products question, 3/5 over x multiplied by 12 over 20<br> what is x
Nitella [24]

Answer:

9/25x

Step-by-step explanation:

3/5/x ×12/20

3/5×1/x ×12/20

36/100x

Divide both by 4

9/25x

The exact value of x cannot be determined because we don't know what the equation is equated to

So we will have to leave the answer as 9/25x
