Answer:
1st question: 32 bikes
2nd question: im not sure maybe 15
Step-by-step explanation:
Answer: 0.068
Step-by-step explanation:
You have to move the decimal place 3 to the left since you're dividing.
Answer:
2, 12, 36, 80
Step-by-step explanation:
Substitute n = 1, 2, 3, 4 into the n th term formula, that is
a₁ = 1³ + 1² = 1 + 1 = 2
a₂ = 2³ + 2² = 8 + 4 = 12
a₃ = 3³ + 3² = 27 + 9 = 36
a₄ = 4³ + 4² = 64 + 16 = 80
So the tenth place is the x in this number 2.x
so rounding to the tenth 5.07
7>5 so round up to 10
5.10
so 13.00
5.10=3 pounds
try and divide by 3
1.7=1 pound
divide 13 by 1.7
13/1.7=7.6 pounds
Answer:
a) Binomial.
b) n=20, p=0.01, k≥2
The probability hat a package sold will be refunded is P=0.0169.
Step-by-step explanation:
a) We know that
- the defective probability is constant and independent.
- the sample size is bigger than one subject.
The most appropiate distribution to represent this random variable is the binomial.
b) The parameters are:
- Sample size (amount of clips in the package): n=20
- Probability of defective clips: p=0.01.
- number of defective clips that trigger the money-back guarantee: k≥2
The probability of the package being refunded can be calculated as:
