You are conducting a study to test whether there is a difference in the mean number of alcoholic drinks consumed per evening bet
salantis [7]

The value of test statistic is 5.45

Data;

  • n1 = 25
  • n2 = 30
  • x1 = 6.2
  • x2 = 3.8
  • s1 = 2
  • s2 = 1

<h3>Test Statistic</h3>

The formula to calculate the test statistic is given as

t = \frac{x_1 - x_2}{\sqrt{\frac{s_1^2}{n_1}+ \frac{s_2^2}{n_2}  } } \\

Let's substitute the values and solve for t

t = \frac{x_1 - x_2}{\sqrt{\frac{s_1^2}{n_1}+ \frac{s_2^2}{n_2}  } } \\t = \frac{6.2 - 3.8}{\sqrt{\frac{2^2}{25} + \frac{1^2}{30}  } } \\t = \frac{2.4}{0.44} = 5.45

The value of test statistic is 5.45

A rectangular board is 1300 millimeters long and 800 millimeters wide. What is the area of the board in square meters?
hichkok12 [17]

Multiply 1300 mm by 800 mm to get 1040000 mm. Then convert this to meters. 1 meter=1000 mm. Therefore, 1040000 mm is the same as 1040 meters.

Triangle B is the same shape as Triangle A with a scale factor of ſ. That means each side length is the side length of Triangle
goblinko [34]

Answer:

that description is already wrong. you must have mistyped something here. please read your own problem description again and then try again. if each side length of triangle B is the side length of triangle A, then they do not only share the same shape (= angles), but they are identical, and the scale factor is simply 1.

I think what you mean is that every side length of B correlates to the side lengths of A by the factor f.

Step-by-step explanation:

what that means :

side a of A = f × side a of B

side b of A = f x side b of B

side c of A = f x side c of B

perimeter of A = f x perimeter of B

for any more details there has to be more information.
