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:
Answer:
the first one : 3/4 ÷ 1/8 = 6
Step-by-step explanation:
remember, dividing something by a fraction is the same as multiplying by the upside-down fraction.
like here
3/4 ÷ 1/8 = 3/4 × 8/1 = 3×8 / 4×1 = 24/4 = 6
you can see that confirmed in the graph, where every 1/4 contains 2/8. so, 1/8 fits 6 times into 3/4.
the other answer options are simply not true
1/8 ÷ 3/4 = 6
1/8 × 4/3 = 4/24 = 1/6 <> 6
6 ÷ 3/4 = 1/8
6/1 × 4/3 = 24/3 = 8 <> 1/8
6 ÷ 1/8 = 3/4
6/1 × 8/1 = 48 <> 3/4
Answer:
y = 7/8x + 7
Step-by-step explanation:
7x- 8y = -56
-7x -7x
-8y = -7x - 56
y = 7/8x + 7
1 byte9 Cube root of b^27 = b^27/3 = b^9.
Answer:
$2.63
Step-by-step explanation:
3 x $0.79 = 2.37
5.00 - 2.37 = $2.63
