What is the domain for √(3x-3)? *

all real numbers except x=1
all real numbers for x≥1
all real numbers for x≥0
all real numbers except x=0

Answers

Domain and range are both
R
Explanation:
Note that your equation describes a line, since it is a polynomial of first degree. As a general result, every non-constant line has domain
R
and range
R
as well.
The domain is
R
because a line is, in particular, a polynomial, and every polynomial can be computed for every
x
.
The range is
R
because a non-constant line is either always growing or decreasing at a constant rate.
This means that, for every line, you always have one of this two situations:
lim
x




f
(
x

lim

f
(
x
)
=

or
lim
x




f
(
x
)
=

,

lim
x



f

)
=


and since every polynomial is continuous, it spans all the possible values from its minimum to its maximum. In other words, every line spans all the possible values from


to

, which means all the real number, thus the range is
R

A politician claims that 20% of the millions of votes cast for his opponent are fraudulent. To test this claim, an investigator collects a random sample of 90 ballots and contacts the voters whose names appear on the ballots to determine if each ballot is in fact fraudulent. Use a normal approximation to find the probability that less than 10 of the selected ballots turn out to be fraudulent, assuming the politician's claim is correct.

Answers

Answer:

"0.0125" is the right solution.

Step-by-step explanation:

The given values are:

Random sample,

n = 90

Claims,

p = 20%

or,

  = 0.20

By using normal approximation, we get

⇒  [tex]\mu = np[/tex]

On substituting the values, we get

⇒      [tex]=90\times 0.20[/tex]

⇒      [tex]=18[/tex]

Now,

The standard deviation will be:

⇒  [tex]\sigma=\sqrt{np(1-p)}[/tex]

On putting the above given values, we get

⇒      [tex]=\sqrt{90\times 0.20\times (1-0.20)}[/tex]

⇒      [tex]=\sqrt{18\times 0.8}[/tex]

⇒      [tex]=\sqrt{14.4}[/tex]

⇒      [tex]=3.7947[/tex]

hence,

By using the continuity correction or the z-table, we get

⇒  [tex]P(x < 10) = P(x < 9.5)[/tex]

⇒  [tex]P(x < 10) = P(\frac{x-\mu}{\sigma} -\frac{9.5-18}{3.7947} )[/tex]

⇒  [tex]P(x < 10) = P(Z < -2.24)[/tex]

From table,

⇒  [tex]P(x < 10) = 0.0125[/tex]

After the last ice age began, the number of animal species in Australia changed rapidly.

The relationship between the elapsed time, t, in years, since the ice age began, and the total number of animal species, S(t), is modeled by the following function:
S(t)=4,200,000⋅(0.72)t

Complete the following sentence about the yearly percent change of the number of animal species.

Every year, _______ percent of species are SUBTRACTED/ADDED from the total number of animal species.

Answers

Answer:

Every year 28 percent of species are SUBTRACTED from the total number of animal species.

Step-by-step explanation:

Exponential growth or decay:

The equation for exponential growth or decay has the following format:

[tex]A(t) = A(0)(1+r)^t[/tex]

In which A(0) is the initial amount and r is the growth/decay rate, as a decimal.

If r > 0, each year r percent is added to the total number, and if r < 0, each year, r percent is decreased from the total number.

In this question:

[tex]S(t) = 4200000(0.72)^t[/tex]

So

[tex]1 - r = 0.72[/tex]

[tex]r = 0.72 - 1 = -0.28[/tex]

Thus

Every year 28 percent of species are SUBTRACTED from the total number of animal species.

Approximately how high above the ground are the windows on the third story of the house?

A.33.5ft
B.28.3ft
C.30.4ft
D.32.0ft

Answers

i could be wrong but 30.4ft

The 28.3 feet high above the ground are the windows on the third story of the house.

It is required to find the height.

What is the Pythagorean Triple?

The Pythagorean triple can be described as any three set of integers representing sides of a right triangle that are solutions to the Pythagorean Theorem, which is given as:

c² = a² + b².

Given that:

Distance between ladder and wall=25 feet

Height of window=20 feet

Closer distance between ladder and wall=15 feet

We know the Pythagoras theorem , we get

[tex]a^{2} +b^{2} =c^{2}[/tex]

we have

a=15 feet

b=?

c=25 feet

So,

[tex]a^{2} +b^{2} =c^{2}\\\\15^{2} +b^{2} =25^{2}\\\\225+b^{2} =625\\\\b^{2}=625-225\\\\b^{2}=400\\\\b=20 feet[/tex]≈28.3 feet

Therefore, the 28.3 feet high above the ground are the windows on the third story of the house.

Evaluate the following:
a) A tea manufacturing company produces normal and green tea bags only. If 52.8% of 36850 total
production is normal tea bags, how many green tea bags are there?

b) If 61.6% of students out of 9855 total students are based in England, how many students are
based in England?

Answers

Answer:

A. Ans: Given,

Solution,

A tea manufacturing company produces normal and green tea bags only.

52.8% of 36850 production is normal tea bags.

Now,

Number of green tea bags=52.8% of 36850

=52.8/100×36850

=19456.8

Therefore, Number of normal tea bags=19456.8

The number of green tea bags is 17384

The number of students is 3071

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

a )

Total production of tea bags = 36850

Percentage of normal tea bags = 52.8 %

Total production of normal tea bags =

Percentage of normal tea bags x Total production

Total production of normal tea bags = ( 52.8 / 100 ) x 36850

                                                            = 19465.8 tea bags

Therefore , total amount of green tea bags = Total tea bags - Total normal tea bags

= 36850 - 19465.8

= 17384.2
≈≈ 17384

Hence , Total amount of green tea bags = 17384.2

b )

Total number of students = 9855

Percentage of students based in England = 61.6 %

Number of students based in England = Percentage of students x Total number of students

Number of students based in England = ( 61.6 / 100 ) x 9855

                                                                = 6070.68

                                                                ≈ 6071

Hence , total number of students based in England = 6070.68

directly left of Alice. How far is Ellen from Alice? If necessary, round to the nearest tenth.

Answers

Answer:

Ellen is 8 Ft. and 5 In. away from Alice .

Step-by-step explanation:

By connecting the people like dots , you'd create a right triangle . The distance between Ellen and Alice would be the slant height .

To find the slant height , you could use the formula stated below .

Formula: A^2 + B^2 = C^2 .

A and B represent the distance between Porter between Ellen , as well as the distance between Porter and Alice . C represents the slant height , or how far Ellen is from Alice .

Substitute the variables with the given information and solve .

Substitution: 8^2 + 3^2 = 73 .

Simplify the final value by finding the square root of it .

√73 = 8.54400374532

As stated in the question , you should round the final value to the nearest tenth if necessary .

8.54400374532 ( Rounded ( Tenth ) = 8.5 Ft.

The rounded value would be 8.5 feet .

The correct option is 4. (0,4)

Given inequalities are [tex]y\geq \frac{1}{2} x^{2} +4[/tex] and [tex]y< \sqrt{x+2}+6[/tex] .

Taking first inequality,

[tex]y\geq \frac{1}{2} x^{2} +4[/tex]

Or, [tex]y=\frac{1}{2} x^{2} +4[/tex]

now checking which option satisfy the above equation.

Taking option 1.(–2, 6)

on putting x= - 2 and y=6, we get

[tex]6= \frac{1}{2} (-2)^2+4[/tex]

[tex]6=6[/tex]

Hence option 1 (–2, 6) satisfy the equation.

Similarly checking for option 2 and 3 we find that these options totally not follow inequality, so option 3 and option 2 must not be the solution of given inequality.

Now option 4 (0, 4).

Putting x=0 and y = 4, we get

[tex]4=0+4\\4=4[/tex]

Hence option 4 also satisfy the first inequality.

Now we have two option to choose our final answer option 1 and option 4.

since option 4 lies in the shaded region so option 4 will be correct option.
