Answer:
1a8?
Step-by-step explanation:
thi is how
The incorrect statement for the given condition is;
⇒ |a| > b
What is Number line?
Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
A number line shows 'a' to the left of 0 and 'b' to the right of 0. Point a is closer to 0 than point b.
Now,
Since, Point a is closer to 0 than point b.
And, Number 'a' to the left of 0 and 'b' to the right of 0.
Hence,
Let the number 'a' = - 1
Then, The number 'b' = 2
So, We get;
|a| = |-1| = 1
And, |b| = 2
Clearly, |a| < b
Thus, The incorrect statement for the given condition is;
⇒ |a| > b

What is the probability that from a sample of 100 Indianapolis residents, fewer than 95% were rooting for the Giants in Super Bowl XLVI
Complete Question
Super Bowl XLVI was played between the New York Giants and the New England Patriots in Indianapolis. Due to a decade-long rivalry between the Patriots and the city’s own team, the Colts, most Indianapolis residents were rooting heartily for the Giants. Suppose that 90% of Indianapolis residents wanted the Giants to beat the Patriots. What is the probability that from a sample of 100 Indianapolis residents, fewer than 95% were rooting for the Giants in Super Bowl XLVI?
Answer:
The value is [tex]P(X < 0.95) = 0.95224[/tex]
Step-by-step explanation:
From the question we are told that
The proportion that wants Giants to win p = 0.90
The sample size is n = 100
Generally the mean of this sampling distribution is
[tex]\mu_{x} = 0.90[/tex]
Generally the standard deviation is
[tex]\sigma = \sqrt{\frac{p(1- p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{ 0.90 (1- 0.90)}{100} }[/tex]
=> [tex]\sigma = 0.03[/tex]
Generally the probability that from a sample of 100 Indianapolis residents, fewer than 95% were rooting for the Giants in Super Bowl XLVI is mathematically represented as
[tex]P(X < 0.95) = P(\frac{ X - \mu_{x}}{\sigma} < \frac{0.95 -0.90}{0.03} )[/tex]
[tex] \frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 0.95) = P(Z < 1.667 )[/tex]
=> [tex]P(X < 0.95) = 0.95224[/tex]
The value of one score in a distribution is changed from X = 20 to X = 30. Which measure(s) of central tendency is (are) certain to change?
Answer:
Mean
Step-by-step explanation:
The three basic measures of central tendencies are mean, median and mode.
Mean can be described as the average value of a set of numbers or scores in a distribution.
One of the ways the mean can be calculated is by dividing the sum of the scores in a distribution by the number of scores in the distribution. This can be represented mathematically as follows:
Mean = Sum of the scores in a distribution / Number of scores in the distribution ........ (1)
Median is the middle number when the scores in a distribution is arranged in ascending or descending order.
Mode is the most frequent number or score in a distribution.
Out of the three basic measures of central tendencies only the mean will certainly change when there is a change in one of the scores. This is because, we can still have the same score as the most frequent and the same number as the median but the mean will change.
For example, we can prove that the mean will certainly change if we assume that the sum of the scores in a distribution is 200 and number of scores in the distribution is 10, wee can substitute this into equation (1) and have:
Mean = 200 / 10 = 20
Now, as given in the question, if the value of one score in the distribution is changed from X = 20 to X = 30. We can obtain the difference as follows:
Difference in score = 30 - 20 = 10
The new mean can be calculated as follows:
New mean = (200 + Diffrence in score) / 20 = (200 + 10) / 20 = 210 / 20 = 21
Therefore, the mean changed by 1 from 20 to 21. This therefore proves that the mean will certainly change.
Of the measures of central tendency, the measure which will certainly change is the mean.
Measures of central tendency include mean, median and mode of a distribution.
The mean refers to the average, hence, the a change in one value in the distribution would certainly change the mean of the distribution.
The mode refers to the highest occurring value in the distribution.
Median denotes the number at the middle of a distribution once it is arranged in order of magnitude.
For instance :
2, 2, 10, 15, 20The mean = (2 + 2 + 10 + 15 + 20) / 5 = 49/5 = 9.8
Mode = 2 (highest occuring)
Median = 10 (middle value)
If X = 20 is changed to X = 30
2, 2, 10, 15, 30The mean = (2 + 2 + 10 + 15 + 30) = 59/5 = 11.8
Mode = 2 (highest occuring)
Median = 10 (middle value)
Therefore, the measure which would certainly change is the mean.

Decide if the situation involves permutations, combinations, or neither. Explain your reasoning. The number of ways 13 people can line up in a row for concert tickets. Does the situation involve permutations, combinations, or neither? Choose the correct answer below.
Step-by-step explanation:
The situation involves permutation. Permutation deals with arrangements of objects. It talks about ways peoples or objects can be arranged with or without restriction. According to the question,
The number of ways 13 people can line up in a row for concert tickets can be expressed as
13! = 13 * 12 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1
13! = 6,227,020,800 ways
Hence the number of ways 13 people can line up in a row is 6,227,020,800 different ways and the situation involves permutation.

Adrian's gerbil weighed 68.59 grams at the beginning of the summer. During the summer, the gerbil gained 24.6 grams.
Estimate the weight of the gerbil at the end of the summer by rounding each value to the nearest whole number.
Answer:
94 grams
Step-by-step explanation:
Adrian gerbil weighed 68.59 grand at the beginning of the summer
During the summer the gerbil gained 24.6 grams
Therefore the weight of the gerbil at the end of the summer can be calculated as follows
= 69 + 25
= 94 grams
Therefore the weight of the gerbil at the end of the summer is 94 grams
The time needed to complete a job is normally distributed with a mean of 1 hour and standard deviation of 10 minutes. Probability to complete the job in hone hour or more, but less than 70 minutes is:
Answer:
The value is [tex]P(60 < X < 70) = 0.34134[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 1 \ hour = 60 \ minutes[/tex]
The standard deviation is [tex]\sigma = 10 \ minutes[/tex]
Generally the 1 hour is equivalent to 60 minutes
Generally the probability to complete the job in one hour or more, but less than 70 minutes is mathematically represented as
[tex]P(60 < X < 70) = P(\frac{60 - 60 }{10 } < \frac{X - \mu}{\sigma } < \frac{70 - 60 }{10 } )[/tex]
=> [tex]P(60 < X < 70) = P(0 < \frac{X - \mu}{\sigma } < 1 )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P(60 < X < 70) = P(0 <Z < 1 )[/tex]
=> [tex]P(60 < X < 70) = P(Z < 1) - P(Z < 0 )[/tex]
From the z table (Z < 1) and (Z < 0 ) is
[tex]P(Z < 1) = 0.84134[/tex]
and
[tex]P(Z < 0 ) = 0.5[/tex]
=> [tex]P(60 < X < 70) = 0.84134 - 0.5[/tex]
=> [tex]P(60 < X < 70) = 0.34134[/tex]
