Answer:
A is 146 and how much is 1 unit for B
Step-by-step explanation:
Answer:
The solution is (2, 2)
Step-by-step explanation:
The solution to a system of equations is the point where the 2 lines intersect. In this graph, the lines intersect at the boxed point, which is (2, 2) because it is 2 on the x-axis and 2 on the y-axis.
Hope this helps!
Answer:
a number with a non repeating and non terminating decimal expansion.
Step-by-step explanation:
Irrational numbers are numbers which cannot be expressed as fractions, they are real numbers which cannot be expressed as rational numbers such as the square root of natural numbers other than perfect squares.
Irrational numbers are non repeating, non terminating decimal numbers with no group of the digits repeated. Therefore the decimal expansion does not terminate but continues without repetition example is π.
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:
The opposite of 4x is -4x and the opposite of -5+4x is 5+-4x
