The weights of 5 girls are 70 pounds, 68 pounds, 85 pounds, 62 pounds, and 70 pounds. Nina finds measures of center and measures

lys-0071 [83]

The Measure of center or measure of variation of the weights are; Range = 23 pounds; Median = 70 pounds; Mean = 71 pounds; Mode = 70 pounds

<h3>How to find the measures of Central Tendency?</h3>

We are given the weights as;

Weights of 5 girls = 70 pounds, 68 pounds, 85 pounds, 62 pounds, and 70 pounds

1) The difference of the least and the greatest values is;

Range = 85 - 62 = 23 pounds

2) The middle value after arranging all the values from least to greatest is; 62, 68, 70, 70, 85

Median = 70

3) Adding all the values and dividing by 5 is;

Mean = (62 + 68 + 70 + 70 + 85)/5

Mean = 71 pounds

4) Value that appeared the most is;

Mode = 70

A manufacturer of household washing machines wants to determine the effectiveness of the type of detergent used (three brands –

ololo11 [35]

Answer:

Two-Factor ANOVA with replication

Step-by-step explanation:

Types of detergent used ( A,B,C ) = 3

Length of time for the washing cycle : A = 18 mins, B = 20 mins, C = 22 mins

number of laundry loads = 18

significance level = 5%

The alternative hypothesis for testing the interaction is a Two-Factor ANOVA with replication this is because the factors that have variations are the : The type of detergent and the length of time for a washing cycle while the load is constant for all.

Simplify the expression, show your work

Mila [183]

Answer:

$\dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}$

Step-by-step explanation:

$\dfrac{\frac{1}{x^2}+\frac{2}{y}}{\frac{5}{x}-\frac{6}{y^2}} =$

To eliminate the denominators of the main numerator and denominator, we multiply the numerator and denominator of the main fraction by the LCD of all small denominators.

The LCD of x^2, y, x, and y^2 is x^2y^2.

$= \dfrac{x^2y^2 \times (\frac{1}{x^2}+\frac{2}{y})}{x^2y^2 \times (\frac{5}{x}-\frac{6}{y^2})}$

$= \dfrac{y^2 + 2x^2y}{5xy^2 - 6x^2}$

$= \dfrac{y(y + 2x^2)}{x(5y^2 - 6x)}$

$= \dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}$
