Answer:

so it's

3/7m<21

and we devide both sides of the inequality.

/2r-1\>7

And we can rewrite it as a compound Inequality

2r-1<7 (or) 2r-1>7 Ima give u the enter

[r<-3 or r>4 I guess it's like this❕

polet [3.4K]

Answer:

The sample size is  n = 1043

Step-by-step explanation:

From the question we are told that

  The lower bound of the range is a = 51

  The upper bound of the range is b =  710

    The margin of error is E = 10

Generally the standard deviation is mathematically represented as

       \sigma =  \frac{b- a}{4}

=>    \sigma =  \frac{710 - 51 }{4}

=>    \sigma = 164.75

From the question we are told the confidence level is  95% , hence the level of significance is    

      \alpha = (100 - 95 ) \%

=>   \alpha = 0.05

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.96

Generally the sample size is mathematically represented as  

    n = [\frac{Z_{\frac{\alpha }{2} } *  \sigma }{E} ] ^2

=> n = [ 1.96  *  164.75 }{10} ] ^2

=> n = 1043

Determine whether the following problem involves a permutation or a combination and explain your answer. How many different ​-le
Alex_Xolod [135]

Answer:

B. The problem involves a combination because the order in which the letters are selected does not matter.

Step-by-step explanation:

Computation technique is a method of statistics to find possible ways of combination. In computation technique it is assumed that order does not matter and letters will be selected at random. Permutation is a statistics technique to find possible ways of combination when the order does matter. Permutation technique cannot be used when order does not matter.

To pass an Examination consisting of four papers, candidates MUST score a mean mark of 40% or above and NOT less than 33% in eac
valina [46]

Answer:

Josephine

Step-by-step explanation:

2 criteria was given to pass an exam:

1. At least, a mean mark of 40% must be achieved in the exam consisting of 4 papers

2. Score at least, 33% in each paper.

From the table given, and considering these two criteria, James definitely didn't pass the examination. He scored below 33% in one of the 4 papers. James scored 30% in Maths

Calculated the mean score for John and Josephine to determine if they meet the first criteria of having at least a mean score of 40%.

Mean score of John = (35 + 36 + 42 + 44) ÷ 4 = 39.25%

Mean score for Josephine = (60 + 55 + 38 + 75) ÷ 4 = 57%

Josephine passed the examination because she had a mean score of 57%, and also scored 33% and above in each test.
