The brain volumes ? ( cm cubed cm3? ) of 20 brains have a mean of 1083.9 1083.9 cm cubed cm3 and a standard deviation of 122.2 122.2 cm cubed cm3. use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. for such? data, would a brain volume of 1348.3 1348.3 cm cubed cm3 be significantly? high?

What is this inequality notation? t is less then or equal to 2

Jace wrote a sentence as an equation. 56 is 14 more than a number. 14+ = 56 which statement best describes jace's work? jace is not correct. the phrase more than suggests using the symbol > and jace did not use that symbol. jace is not correct. he was correct to use addition, but the equation should be 56+ p = 14 jace is not correct. the first number in the sentence is 56, so the equation should start with 56. jace is correct. the phrase more than suggests addition, so jace showed that 14 plus a variable equals 56. o
