The time spent waiting in the line is approximately normally distributed. The mean waiting time is 55 minutes and the standard deviation of the waiting time is 33 minutes. Find the probability that a person will wait for more than 88 minutes. Round your answer to four decimal places.

Answer: The correct answer is c

Step-by-step explanation:

Graph C depicts an odd function.

We have the four graphs as shown in the figure.

We have to determine which graph depicts an odd function.

Assume a function f(x), if :  [tex]f(-x) = -f(x)[/tex] i.e., absolute value remains the same if the sign of the independent variable is reversed.

Remember - A function is called even if its graph is symmetrical about the y - axis, odd if its graph is symmetrical about the origin.

It can be seen that - Graph A, Graph B, Graph D are not symmetrical about the origin. Only Graph C - Sine wave is symmetrical about Origin.

Hence, Option C is the graph that depicts the odd function.

Step-by-step explanation:

i think this is correct

Answer:

You must move the a and 8 to the other side of the equation. Just divide both sides by 8a.

B = c \ 8a.. c over 8a

The value for b is c/8a.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

8ab=c

Now, solving for b

8ab= c

ab= c/8

or, b = c/8a

Hence, the value for b is c/8a.

Step-by-step explanation:

Let p= probability of the students in a university are baseball players.

Given: p= 0.40 , sample size : n= 781

The probability that the sample proportion of baseball players will be greater than 43% will be:

[tex]P(p>0.43)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.43-0.41}{\sqrt{\dfrac{0.41(1-0.41)}{781}}}\\\\=P(Z>1.14)\ \ \ [Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(Z<1.14)\\\\=1- 0.8729=0.1271[/tex]

Hence, the probability that the sample proportion of baseball players will be greater than 43% = 0.1271

Angles RLN and KLM would be a linear pair.

Angles RLN and MLK would be vertical angles.

Vertical angles are formed when their sides share the same lines. RL shares the same line with LM and NL shares the same line with LK (see the attached diagram), so that means both angles form a vertical pair.

Answer:

The 95% confidence interval is

    [tex]0.5055<  p <0.5725[/tex]

Step-by-step explanation:

From the question we are told that

  The sample size is  n =  850

  The number of can of people that will vote in a two people race is k =  458

Generally the sample proportion is mathematically represented as

        [tex]\^ p = \frac{k}{n}[/tex]

=>     [tex]\^ p = \frac{458}{850}[/tex]

=>     [tex]\^ p = 0.539[/tex]

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

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of   is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \sqrt{\frac{\^ p(1- \^ p)}{n} } [/tex]

=>   [tex]E = 1.96 *  \sqrt{\frac{0.539(1- 0.539)}{850} } [/tex]

=>  [tex] E =  0.0335[/tex]

Generally 95% confidence interval is mathematically represented as  

             [tex]\r p -E <  p <  \r p +E[/tex]

=>          [tex] 0.539 - 0.0335<  p < 0.539 + 0.0335[/tex]

=>          [tex]0.5055<  p <0.5725[/tex]

Answer:

The range of scores that can earn Jeremiah a B in the course is 80 - 100

Step-by-step explanation:

Average = total scores/number of exams

For an average of 80, considering the final score has twice the weight of the previous exams;

Note: since the final score has twice the weight of previous exams, it is considered a double score and counted twice

Let the lowest final score for a B grade be y

80 = (69 + 78 + 81 + 92 + 2 * y)/6

80 * 6 = (320 + 2y)

2y = 480 - 320

y = 160/2

y = 80

Let the highest final score for a B grade be z

89 = (69 + 78 + 81 + 92 + 2 * z)/6

89 * 6 = (320 + 2z)

2z = 534 - 320

z = 214/2

z = 107

Since, the highest score in the exam cannot exceed 100,

Therefore, the range of scores that can earn Jeremiah a B in the course is 80 - 100

Answer:

Company C has the lowes cost per tiger at $2.74. (Divide the prices by the number of stuffed animals, in this case, $41.10/15)

$2.26 would be their profit.

Step-by-step explanation:

To find how much money they have to pay for each stuffed animal, you have to divide the prices by the number that would be sold. For example, for Company C, it would be $41.10 divided by 15. When you do that with all the companies, you'll find the Company C is the cheapest.

You find their profit by subtracting $2.74 from $5. They sell it for $5, but they did have to use $2.74 to buy the stuffed animals. $5 - $2.74 = $2.26

Hope this helps! ^-^

Company C has the lowest cost per tiger.

Students will make a profit of $2.26 for each tiger sold.

The division is the process of dividing a number by a given number.

Note that company A offers 12 tigers for $33.24, therefore, divide 33.24 by 12 to get the cost of one tiger,

Cost of one tiger in company A = $33.24/12 = $2.77

Similarly,

The cost of one tiger in Company B = $44.80/16 = $2.8

The cost of one tiger in Company C = $41.10/15 = $2.74

Clearly, company C has the lowest cost per tiger.

Now, students will buy tigers from Company C for $2.74 per tiger and sell them for $5, therefore, the profit from selling one tiger will be 5-2.74=2.26.
