That would depend...
-4 / -2 = 2........4 / 2 = 2 <== if the signs are the same
but
4 / -2 = -2.......-4 / 2 = -2 <== if the signs are different
So basically, if the signs are the same, the result is positive and if the signs are different, the result is negative
-np-90+90<30+90
-np<120
-np/-p<120/-p
= n>-120/p
And the answer is = n> -120/p
hey its -100 percent. the negative to show decrease.
Answer:
7 three-course meals
Step-by-step explanation:
7 x 15= 105
141-105= 36
36/12= 3
7+3= 10
So total, there are 10 meals; 7 three-course and 3 two-course
1/6*1/6*1/6*1/6 = 1/1296 = 0.078% probability of ANY 4-letter sequence (including qqqq)
1000/1296 is less than 1.
Expected number of times qqqq (or any given 4-letter sequence) will appear in 1000 letters is 0.
