I believe the answer is D. 36 , sorry if I'm wrong !
We can already tell if a quotient is negative if the divisor or the dividend is a negative number. (Only 1 negative number and 1 positive number, because if there are two negative numbers then the outcome will be a positive.)
Question 4 has one negative number in it so it's already visible that the quotient is already negative. And if we did divide it the answer will be -1.
Question 3 has two negative numbers so we know that the outcome is a positive number. If solve the quotient is 0.023931813 which is clearly not a negative number.
Question 2 has one negative number so the answer will be negative. The quotient will be -23.80952381, which is clearly a negative number.
Question 1 doesn't have any negative numbers so the outcome will also be a positive number. The quotient for question 1 is 0.231578947.
So questions 2 and 4 both have negative quotients. While, questions 1 and 3 have positive quotients.
Answer:
234556678
Step-by-step explanation:
mu = 1100 = population mean
sigma = 275 = population standard deviation
x = 1400 = raw score
z = z score
z = (x-mu)/sigma
z = (1400-1100)/(275)
z = 300/275
z = 1.0909090909091 approximately
z = 1.09
Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).
The positive z score is due to Paula's raw score being above the mean.
