Answer:
8p
Step-by-step explanation:
5p-4=3p+6
-3p from 5p
2p-4=6
+4 at 4 to the 6
2p=10
divide 2p=10
8p
this should be right but not 100% thanks for the points
2x^2 + 5x - 3 = 0
(2x + 1 )(x + 3 ) =0
The zeroes are x = -3 and x = 0.5
The graph is a parabola opening upwards and it cuts the x-axis at (-3,0) and (0.5,0).
An exponential model should be used to represent the <em>n</em>th pattern. The squares do not have a constant growth pattern, but rather they are growing exponentially, because the pattern they are growing at is 2,4,8. A constant pattern would be 2,4,6. I would show the work on a linear graph - plotting the lines on the graph at 1,2, 2,4 and 3,8 your arrow would be curved and pointed up.
Mean = (93 + 73 + 76 + 86 + 98) / 5 = 426/5 = 85.2
Variance = ((93 - 85.2)^2 + (73 - 85.2)^2 + (76 - 85.2)^2 + (86 - 85.2)^2 + (98 - 85.2)^2) / 5 = (60.84 + 148.84 + 84.64 + 0.64 + 163.84) / 5 = 458.8 / 5 = 91.76
standard deviation = sqrt(91.76) = 9.58
