In order to calculate standard deviation, apply the standard deviation formula, which is given in the attached file. In this formula, we are finding the square root of the sum of the square of given values less their mean value (the sum of the given numbers divided to their amount) divided to N-1, where N is the amount of the given numbers. When we calculate the mean, it is 42.7 and the standard deviation is 10.02275
Answer:
Step-by-step explanation:
Factors of 9: 1, 3 and 9.
Negative Factors of 9: -1, -3 and -9.
Prime Factors of 9: 3.
Prime Factorization of 9: 3 × 3 = 32
Sum of Factors of 9: 13.
80 is correct each of the triangles are 2x2/2 therefore 1 triangle is 2 multiples by 4 so all triangles equal to 8 units. The rectangles are 6 by 2 so 6 multipled by 2 multiplied by 2 again because there are 2 rectangles is 24. 8+24=32. Middle section is 8x6 and that equals to 48. 48+32 is 80 therefore the area of this figure is 80 units

Answer:
-9, -5, -4.1, -4
Step-by-step explanation:
I think what you're missing here is that there is a negative sign in front of the q. This means that whatever number you put in for q will be multiplied by negative 1. Positive numbers will become negative, and negative numbers will become positive.
If you substitute 9 for q you will get 
, which is clearly not true, because -9 is way less than 4.
For writing the equation you divide both sides by -1. When you do this however, you must flip the inequality sign
the > sign turned into <, and the q and 4 switched signs.
