Answer: Frequencies .

Step-by-step explanation:

In statistics theory the chi-square test statistic is calculated by considering each cell and the expected frequency is subtracted from the observed frequency after that the difference is squared, and the total is divided by the expected frequency. This is highlight that the key focus of the chi-square test is the frequencies .

Quick i need help so bad :(
Vanyuwa [196]

There are 4 triangles with base of 5 and height of 8.4

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 5 x 8.4 = 21 m^2

Multiply by 4 = 21 x 4 = 84 m^2

Area of the base = length x width = 5 x 5 = 25 m^2

Total area = 84 + 25 = 109 m^2

7,,,,,,,,,,,,,,,,,,,,please help
Goryan [66]

Answer:

1

Step-by-step explanation:

The given expression is

\frac{2^{\frac{11}{2} }\times 2^{-7}\times 2^{-5}}{2^3\times 2^{\frac{1}{2} }\times 2^{-10}}

Recall and use

a^m\times a^n=a^{m+n}

\frac{2^{\frac{11}{2} -7-5}}{ 2^{3+\frac{1}{2} -10}}

\frac{2^{-\frac{13}{2}}}{ 2^{-\frac{13}{2}}}

Same bases are dividing, so we write one base and subtract the exponent.

2^{-\frac{13}{2}+\frac{13}{2}}

2^0=1
