Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 86 people in the 18-21 age bracket and finds that 74 of them respond and 12 refuse to respond. When 257 people in the 22-29 age bracket are contacted, 236 respond and 21 refuse to respond. Suppose that one of the 343 people is randomly selected. Find the probability of getting someone in the 22 dash 29 age bracket or someone who refused to respond.

Determine whether the underlined value is a parameter or a statistic. Telephone interviews of 1 comma 502 adults 18 years of age or older found that only Modifying 69 % with underline could identify the current vice dash president. nothing Is the value a parameter or a statistic? A. The value is a statistic because the 1 comma 502 adults 18 years of age or older nothingare a sample. B. The value is a parameter because the 1 comma 502 adults 18 years of age or older nothingare a population. C. The value is a statistic because the 1 comma 502 adults 18 years of age or older nothingare a population. D. The value is a parameter because the 1 comma 502 adults 18 years of age or older nothingare a sample.

When vector vector A is added to vector Vector B, the resultant is vector vector R such that vector R is equal to vector A plus vector B. This resultant vector has components vector R sub x is equal to vector A sub x plus vector B sub x and vector R sub y is equal to vector A sub y plus vector B sub y. What is the y-component of the resultant vector vector R is equal to vector A plus vector B when you add vector A and Vector B?

Amber, Bernie, and Carlos are working on a problem together. Their goal is to correctly apply the difference of cubes formula to factor 2x5−250x2.Here is their plan:First, factor the greatest common factor out of the expression.Next, identify a and b.Finally, use the difference of cubes method to factor the expression.Each person followed the steps and arrived at a different answer. Read each student’s work and identify who followed the steps correctly.Amber's work:First, factor out 2x2:2x5−250x2=2x2(x3−125). Next, identify a and b:a=x, b=125. Finally, follow the pattern to get 2x2(x−125)(x2+125x+15,625).Bernie's work:First, factor out x2:2x5−250x2=x2(2x3−250). Next, identify a and b:a=2x; b=250. Finally, follow the pattern to get x2(2x−250)(4x2+500x−62,500).Carlos' work:First, factor out 2x2:2x5−250x2=2x2(x3−125). Next, identify a and b:a=x; b=5. Finally, follow the pattern to get 2x2(x−5)(x2+5x+25).Which statements accurately analyze why each student is correct or incorrect?There may be more than one correct answer. Select all correct answers.Amber is incorrect because 125 is equal to b3, not b.Bernie is incorrect because x2 is not the GCF of the polynomial.Bernie is correct because he correctly factored the GCF, identified a and b, and applied the difference of cubes method.Carlos is incorrect because 5 is equal to b√3, not b.Carlos is correct because he correctly factored the GCF, identified a and b, and applied the difference of cubes method.Amber is correct because she correctly factored the GCF, identified a and b, and applied the difference of cubes method.
