<span>Write
an algebraic expression for three fourths the square of b
=> Algebraic expression is the expression that shows both integers,
variables, symbols and operations like addition, subtraction, division, and
multiplication.
=> three fourth is a fraction which is equals to 3/4
=> square of b is an exponent which is equals to b<span>2
</span>=> thus, the algebraic expression of three fourths the square of b is
equals to:
=> ¾ x b2 or 3b2 / 4</span>
Answer:Since the integers are closed under addition, . m C n C 1/ is an integer, and hence the last equation shows that x C y is even. Therefore, we Page 3 Appendix C. Answers for Exercises 539 have proven that if x and y are odd integers, then x C y is an even integer. P1 There exists an integer k m D 2k.
Step-by-step explanation:
Answer:
No.
Step-by-step explanation:
The definition of a function is that every output (x) has only one input (y).
Here -3 gives two different outputs which contradicts the definition of a function.
<span>The probability that at least 10% of the boards are defective is:
7.35%
The probability of exactly 10 units being defective is:
9.634%
With 250 samples the distribution of percent of boards failed can be approximated as a normal distibution. The standard deviation of binomial random variable is
sqrt(n*p*(1-p))
where p is the probability of failure.
This gives a standard deviation of 3.44601 and 10% deviates from the 5% mean by 1.45 standard deviations. Looking this up on a standard deviation chart shows that
7.35% of 250 unit samples will exceed or meet a 10% failure rate
The formula for the probabilty of a certain number of sucesses occuring is
(n choose k)*(p^n)*((1-p)^(n-k))
where p is the probability of success
n is the number of trials
n choose k is the best way i have of writing the binomial coefficient
and
k is the number of successes
the answer is found by letting
p=.95
n=250
k=240</span>
kilometers is larger. This is because when you convert 6 Kilometers into meters you get 6000 which is surely larger then 5,998 I hope this answers you question.
