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 .
AnsweTo see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.r:
Step-by-step explanation:
Answer:
1 pounds is equal to 4535 kilograms.
The distance from the satellite to the Earth's horizon is 6398 km
<h3>
Pythagoras theorem</h3>
Pythagoras theorem is used to show the relationship between the sides of a right angled triangle. It is given by:
Hypotenuse side² = Adjacent side² + Opposite side²
Let x represent the distance from the satellite to the Earth's horizon
Hence:
- x² = 6370² + 600²
- x² = 40936900
- x = 6398 km
The distance from the satellite to the Earth's horizon is 6398 km
