When choosing an interval to use for a frequency table, the low value and the high value of the dat is considered so that the interval refrects a true data size for all the intervals.

Given that a<span> data set has values ranging from a low of 10 to a high of 52. Using the class limits of 10-19, 20-29, 30-39, 40-49 for a frequency table will make the last interval not to refrect the true size of the other intervals. i.e. the last interval will be 50 - 52 which has a size of 3, different from the size of 10 the other intervals have.</span>

In a network of 40 computers, 5 hold a copy of a particular file. Suppose that 7 computers at random fail. Let F denote the numb
anzhelika [568]

Answer:

a. E(F)=0.875

b. 99.9976%

c. P(X=2)=0.1683

Step-by-step explanation:

a. We notice that this is a binomial distribution with the probability of success;

p=\frac{5}{40}=0.125

#We are given the sample size, n=7. The Expected value is calculated as:

E(X)=np\\\\E(F)=np , n=7, p=0.125\\\\E(F)=7\times 0.125\\\\=0.875

Hence the expectation, E(F)=0.875

b. To calculate the probability of the range of F, we need to calculate all possible outcomes of F in the given sample;

P(X\leq 5)=1-P(X=6)-P(X=7)\\\\=1-{7\choose 6}(0.125)^6(1-0.125)^1-{7\choose 7}(0.125)^7(1-0.125)^0\\\\=1-0.000023365-0.000000476\\\\=0.999976158\\\\=99.9976\%

Hence, the range of F is 99.9976%

c. The probability that F=2 is calculated  using the binomial distribution function as:

P(X=2)={7\choose 2}(0.125)^2(1-0.125)^5\\\\=0.1683

Hence, the probability of F=2 is 0.1683

To determine whether the inverse of a function is a function, you can perform the vertical line test. A. True B. False
Andreas93 [3]
I think it's A since u would normal use the vertical line test on a line on a graph to see if it's a function.
