No, it equals positive 9. Any negative number squared will always give a positive result; the square root of a negative number is always imaginary (a mathematical term, referring to 'i'). So, (-3)2 = 9 and -32 = -9.
1. 1x1=1
sum of scores: 24 mean of scores : 24/4 = 6 squared deviations from the mean: 9, 4,4,9 sum of these: 26 sample variance: 26/4 = 6.5
The chi-squared test is used to compare the observed results with the expected results. If expected and observed values are equal then chi-squared will be equal to zero. If chi-squared is equal to zero or very small, then the expected and observed values are close. Calculating the chi-squared value allows one to determine if there is a statistical significance between the observed and expected values. The formula for chi-squared is: X^2 = sum((observed - expected)^2 / expected) Using the degrees of freedom, use a table to determine the critical value. If X^2 > critical value, then there is a statistically significant difference between the observed and expected values. If X^2 < critical value, there there is no statistically significant difference between the observed and expected values.
To simplify the ratio 21 to 27, you need to find the greatest common divisor (GCD) of the two numbers, which is 3. Divide both numbers by 3 to simplify the ratio: 21 ÷ 3 = 7 and 27 ÷ 3 = 9. Therefore, the simplified ratio of 21 to 27 is 7 to 9.
-9
3 squared is equal to 9
3 squared is 3 x 3 or 9.
three squared = 3^(2) = 3 x 3 = 9 The answer!!!!!
No, three squared is nine. 3(squared sign) =3x3 =9
9
3 squared is 9, 5 squared is 25. So the product is 225.
(-3)^2 = 9
Yes, indeed. 3 feet squared is 9 square feet.
No. For it to work, then 3 squared and 4 squared would have to be equal to 6 squared. 4 squared=16 3 squared= 9 9+16= 25 6 squared= 36.
3 squared is equal to 3 x 3 = 9
(-3)2 = 9
2^2 + 3^2 = 4 + 9 = 13
