Answer:
1.) The forth choice seems about right
2.) x = 38 (if and only if the forth answer choice for question 1 is right)
Week 1=50
week 2= 50×2=100
week 3=100×2=200
week 4=200×2=400
week 5=400×2=800
week 6=800×2=1600
week 7=1600×2=3200
week 8=3200×2=6400
so the answer is 6400
=> 38% of students at a college failed mathematics
=> 27% failed physics, and=> 9% failed both. A student is selected at random.
a)If a student failed physics, what is the probability that he or she failed math?
=> 1/38
b)If a student failed math, what is the probability he or she failed physics?
=> 1/27
c) What is the probability that he or she failed math or physics?
=> 1/9
Answer:
8 balls, 7 balls, 6 balls, 5 balls, 4 balls
Step-by-step explanation:
Since there are three blue balls & there maybe five additional balls with different colors, then the three balls can be taken as a single unit during arrangement/combination.
If the number of other balls with different colors aside blue is 5, the value of M will be 8.
If the number of other balls with different colors aside blue is 4, the value of M will be 7.
If the number of other balls with different colors aside blue is 3, the value of M will be 6.
If the number of other balls with different colors aside blue is 2, the value of M will be 5.
If the number of other balls with different colors aside blue is 1, the value of M will be 4.
Answer:
m=-4k + 3f -7
Step-by-step explanation:
-5m = 20k - 15f + 35
Divide both sides by -5
