Kitty [74]

Answer:

20 cups

Step-by-step explanation:

Let the small pitchers be given by s

and the larger pitchers by l

According to the given information:

2s + l = 8....(1) \\ and \\ l - s = 2 \\ l = s + 2...(2) \\ substituting \: l = s + 2 \: in \: equation \: (1) \\ 2s + s + 2 = 8 \\ 3s = 8 - 2 \\ 3s = 6 \\ s =  \frac{6}{3}  \\ \huge \red{ s = 2} \\ substituting \:   s  = 2 \: in \: equation \: (2)  \\ l = 2 + 2 \\ \huge \purple{ l = 4}\\\\Now\\ 3l +4s \\= 3\times 4+4\times 2\\= 12 +8\\= 20\: cups

So, 3 large pitchers and 4 small pitchers hold 20 cups of water.

Alika [10]

Answer:

Mean = 78 ;

Standard deviation = 14

Step-by-step explanation:

Given that:

Mean score = 68

Standard deviation = 14

When a constant value is added to the individual value of a dataset, the new mean value will become the sum of the initial mean value and the constant term added to the values.

Constant Added score = 10

The mean of scaled test score will be:

Mean score + constant added score

68 + 10 = 78

The standard deviation remains unchanged ; Hence, standard deviation = 14
