Answer:

what is the question. the equation is invalid.

Answer:

-9>2x+15

Step-by-step explanation:

Answer:

Population = 75,342 households

Sample = 400 randomly selected households

The percentage who live in a single household unit = Parameter

The average of 2.9 person per household of all households in the city = parameter

The $65,000 median family income of all the households in the city = Parameter

Step-by-step explanation:

The population refers to all the entire elements, observations or subject which fits into a particular study. In the scenario above, the entire household in the city of study. That is, the 75,342 households.

The sample is the subset of the population which is a smaller set of observation meant to be representative of the larger population. The sample here is the 400 randomly selected households.

Parameter differs from statistics in that numerical estimates or calculations obtained from the population is called the parameter while the numerical characteristics derived from the sample is called statistic.

In this exercise we have to use the knowledge of probability to calculate the chances of choosing a TV approved by the quality control, so:

400  randomly selected households

So, based on the information given in the statement, we have:

Some parameters for this equation are:

The inhabitants of a place refers to all the complete essential feature, attention or subject that fits into the study. In the sequence of events above, the complete household fashionable the city of study. That is, the 75,342 households.

The sample exist the subset of the inhabitants of a place that exist a tinier set of comment on something scrutinized intend expected representative of the best inhabitants of a place. The sample in this place happen the 400 carelessly picked households.

Answer:

PQ = ST

Step-by-step explanation:

..................

Answer:

pq = st

Step-by-step explanation:

Answer:

P = perimeter

A = area

l = lenght

w = width

P = 2 x l + 2 x w

A = l x w

18 ft = 2 x l + 2 x w

18 ft² = l x w

Input l = 6 ft w = 3 ft

18 ft = 12 ft + 6 ft = 18 ft

18 ft² = 6 ft x 3 ft = 18 ft²

Answer:

l = 6 ft

w = 3 ft

Step-by-step explanation:

let the length be l and breadth be b.

perimeter = 2(l +b)

18 = 2(l+ b)

9 = l+ b

b = 9-l .... eq - 1

area = l× b

18 =l ( 9-l)

18 = 9l - l²

l²- 9l + 18 = 0

l ² -3l - 6l +18 = 0

l (l -3) -6 ( l -3) = 0

(l - 6 ) ( l-3) = 0

length (l). = 6 or 3 ft

then breadth = 9-l = 9-3 or 9-6

= 6 or 3 ft

Answer:

-19

Step-by-step explanation:

Answer:

1) Between 12.5 miles and 21.7 miles.

2) b) 75%

3) c) 95%

4) Between 13.7 miles and 20.5 miles.

Step-by-step explanation:

Empirical Rule:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviations of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

Chebyshev Theorem:

The Chebyshev Theorem can also be applied to non-normal distribution. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]P = 100(1 - \frac{1}{k^{2}})[/tex].

1) According to Chebyshev's theorem, at least 36% of the commute distances lie between miles and miles.

Within k standard deviations of the mean, and k is found when [tex]P = 36[/tex]. So

[tex]P = 100(1 - \frac{1}{k^{2}})[/tex]

[tex]36 = 100 - \frac{100}{k^2}[/tex]

[tex]\frac{100}{k^2} = 64[/tex]

[tex]64k^2 = 100[/tex]

[tex]k^2 = \frac{100}{64}[/tex]

[tex]k = \sqrt{\frac{100}{64}}[/tex]

[tex]k = \frac{10}{8}[/tex]

[tex]k = 1.25[/tex]

Within 1.25 standard deviations of the mean.

1.25*3.7 = 4.6 miles

17.1 - 4.6 = 12.5 miles

17.1 + 4.6 = 21.7 miles

Between 12.5 miles and 21.7 miles.

2) According to Chebyshev's theorem, at least of the commute distances lie between 9.7 miles and 24.5 miles.

17.1 - 9.7 = 24.5 - 17.1 = 7.4 miles, so within 2 standard deviations of the mean, which is 75%, option B.

3) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately of the commute distances lie between 9.7 miles and 24.5 miles.

Within 2 standard deviations of the mean, by the Empirical Rule, which is 95%, option c.

4) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 68% of the commute distances lie between miles and miles.

Within 1 standard deviation of the mean.

17.1 - 3.4 = 13.7

17.1 + 3.4 = 20.5

Between 13.7 miles and 20.5 miles.

Answer:

X = 114

Step-by-step explanation:

if one corner is 33 degrees. and the opposite corner is the same then you know that makes 66 degrees.

you take that minus 180. so 66 - 180 which leaves 114.

so X is 114

Answer:

All Registered voters in the state

Step-by-step explanation:

The random sample utilized involves a random subset of citizens from each of the 3 largest cities in the state. The larger group which consists of all set of observation from which the smaller sample used in the survey was chosen is called the population.

Hence, the relevant population may be said to encompass all citizens of the state who have attained voting age and are registered, hence, all citizens in the state who are registered voters.

Answer:

Step-by-step explanation:

words algebraic symbols reason

two decreased by a number   2 - x   start with 2, make it smaller

a number decreased by two   x - 2   start with a number, make it smaller

two less than a number   x - 2   start with a number, make it smaller

four more than a number   x + 4 or 4 + x   start with a number, add 4

the sum of 4 and a number   x + 4 or 4 + x   add to get a sum

the opposite of the sum of a number and three  -(x+3) or -(3+x)   take sum, take opposite of sum

     It may be convenient for the reader to use the technique the author used in writing the reason column.

Think of the word expression as a task to be completed by a computation.

Determine the operations needed.

Think how one would start and, then

think of what would need to be done to complete the task described.

     Notice the uses of the preposition "of" in the last example. Prepositional phrases break up the expressions into pieces. Those beginning with "of" are discussed on the last page.

     Below, notice how the prepositional phrases, in blue, which begin with by, between, from, and than, make it easier to examine the phrase and determine where to start and what to do.

the opposite of the sum of a number and three  -(x+3) or -(3+x)   take sum, take opposite of sum

     Additional information is found in a prepositional phrases. The preposition "from" is almost always a tip-off that subtraction is required. Often, the desired mathematical expression starts with what is in the "from" prepositional phrase.

Multiplication & Division

     Here are words associated with multiplication or division. The context is the key to the symbols needed, not the word itself. Remember, the word AND is a signal that there are two or more ideas, not that addition is required. Remember, to use prepositional and other phrases to break up the expression in order to determine what is required. Examples follow the list.

the product of two and a number   2x or 2(x)   multiply

Answer: n=

−z2−5

z

Step-by-step explanation:

Let's solve for n.

(−n)(z)−z2−2=3

Step 1: Add z^2 to both sides.

−nz−z2−2+z2=3+z2

−nz−2=z2+3

Step 2: Add 2 to both sides.

−nz−2+2=z2+3+2

−nz=z2+5

Step 3: Divide both sides by -z.

−nz

−z

=

z2+5

−z

Answer:

-z^2-5z

Step-by-step explanation:

To evaluate a polynomial at a given value, we substitute the given value for the variable and then simplify using order of operations. We are given n=3, so we substitute 3 for n in the polynomial −nz−z2−2z and simplify as follows.

−nz−z2−2z

−(3)z−z2−2z

−3z−z2−2z

−z2−5z
