Because n > 30, the sampling distribution of the mean ages can be approximated by a normal distribution with mean µ and standard deviation σ ÷ √(45) .The central limit theory applies whenever n > 30. Because n > 30, the sampling distribution of the mean ages can be approximated by a normal distribution with mean µ and standard deviation σ ÷ √(n) .
We can say that lines A and D are <em>perpendicular</em>.
Answer:
Step-by-step explanation:
Use distributive property to simplify both sides.
Use the Golden Rule of Algebra: (<em>What</em><em> </em><em>we</em><em> </em><em>do</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em>,</em><em> </em><em>we</em><em> </em><em>must</em><em> </em><em>do</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>)</em><em>.</em>
Answer: -8 and 6
Step-by-step explanation:
factors of 48: 1,2,4,6,8,12,24,48
1 x 48
2 x 24
4 x 12
6 x 8
for a negative product, one of the factors must be negative and the other positive.
for two number to have a sum of -2, the greater number must be the negative number, and both numbers should have be two values apart (ex. 6 and 8, 3 and 5, 12 and 14, etc.). In this case, 8 would have to be negative whereas 6 will be left positive.
and then we check:
-8 x 6 = 48
-8 + 6 = -2
