If you would like to solve the equation 3 3/4 * a + 3 + 6 = 87, you can do it using the following steps:
3 3/4 * a + 3 + 6 = 87
15/4 * a = 87 - 3 - 6
15/4 * a = 78 /*4/15
a = 78 * 4/15
a = 104/5
a = 20.8
The correct result is 20.8.
The equation would be Y=15x+150 because 10% of 150 is 15. Next you coun up how many months you have up untill August and replace the x with it. So the equation would be Y=15(7)+150. ___Y=105+150___Y=$255. So $255 would be your answer.
Answer:
They are parallel
Step-by-step explanation:
They both start with y=2/3x so you know the slope is the same. The +4 and -1 are just the intercepts
Answer:
The probability of selecting a students that drinks sugar free red bull is <em><u>0.1</u></em>
Step-by-step explanation:
In this question, we are concerned with calculating probability that out of the 120 students interviewed, a student chosen at random drinks sugar free red bull.
Mathematically, the probability is = number of students that drinks sugar free red bull/Total number of students interviewed
We know the total number of students interviewed, but we do not know the number of students that drink sugar free red bull.
Now looking at the question, we can see that all the students interviewed has the choice of having only to drinks, monster or red bull.
Since 72 students drink monster, the number of students that take red bull = 120 - 72 = 48
Now from this 48, we have a ratio. The ratio of regular type to sugar free is 3:1. The number taking sugar free is thus 1/4 × 48 = 12 students
The probability of choosing a student that drinks sugar free red bull is thus 12/120 = 1/10 = 0.1
-4.2, -4 1/2, -4.7, -5 1/4, -5.5
