in a survey of more than 3000 people 93% of the respondents claimed to prefer Isaac's immaculate ice cream over any other brand of ice cream. which of the folloling groups were surveyed.

The answer is 2,790.

Step-by-step explanation:

Here's a handy tool.

93% of 1 = 0.9393% of 131 = 121.8393% of 261 = 242.7393% of 391 = 363.63

93% of 2 = 1.8693% of 132 = 122.7693% of 262 = 243.6693% of 392 = 364.56

93% of 3 = 2.7993% of 133 = 123.6993% of 263 = 244.5993% of 393 = 365.49

93% of 4 = 3.7293% of 134 = 124.6293% of 264 = 245.5293% of 394 = 366.42

93% of 5 = 4.6593% of 135 = 125.5593% of 265 = 246.4593% of 395 = 367.35

93% of 6 = 5.5893% of 136 = 126.4893% of 266 = 247.3893% of 396 = 368.28

93% of 7 = 6.5193% of 137 = 127.4193% of 267 = 248.3193% of 397 = 369.21

93% of 8 = 7.4493% of 138 = 128.3493% of 268 = 249.2493% of 398 = 370.14

93% of 9 = 8.3793% of 139 = 129.2793% of 269 = 250.1793% of 399 = 371.07

93% of 10 = 9.3093% of 140 = 130.2093% of 270 = 251.1093% of 400 = 372.00

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
