Answer:

To reduce bias when estimating mean commuting time

Step-by-step explanation:

Given that the selection of adults is based on the three strata found in the region; urban, suburban, and rural areas where the population and proportion of adults commuting to work is progressively decreasing, using a uniform number or sample size will not increase sample error as there are more commuters in the urban areas than in the suburban or rural areas, likewise, there are more commuters in the suburban area than in the rural areas, and as such the proportion of those sampled in the urban  areas should be more than those surveyed in the suburban while those surveyed in the suburban areas should be more than those surveyed in the rural areas to reduce bias when estimating the mean as there will be more general representation.

Answer:

The slope of the line is  [tex]-\frac{1}{7}[/tex]

Step-by-step explanation:

The rule of the slope of a line which passes through points

(x1, y1) and (x2, y2) is

∵ The line passes through points (19, 8) and (-2, 11)

∴ x1 = 19 and x2 = -2

∴ y1 = 8 and y2 = 11

→ Use the rule above to find the slope of the line

∵ [tex]m=\frac{11-8}{-2-19}=\frac{3}{-21}[/tex]

→ Simplify the fraction by divide up and down by 3

∴ [tex]m=-\frac{1}{7}[/tex]

∴ The slope of the line is  [tex]-\frac{1}{7}[/tex]

remember to find common denominators!

Answer:

2/3

Step-by-step explanation:

To subtract fractions we need a common denominator.

Let's make 1/4 have the same denominator as 11/12.

Multiply by 3 so we get 3/12.

Then we can subtract.

11/12-3/12=8/12

We can simplify this to 2/3

Answer:

Part a: A square and a rhombus both have sides of equal length.

Let's calculate the length of each side.

[tex]\overline{PL}: \sqrt{(0-5)^2+(3-3)^2}=\sqrt{25+0}=5\\\overline{LA}\sqrt{(5-2)^2+(3-(-1))^2}=\sqrt{3^2+4^2}=5\\\overline{AN}:\sqrt{(2-(-3))^2+(-1-(-1))^2}=\sqrt{25+0}=5\\\overline{NP}:\sqrt{(-3-0)^2+(-1-3)^2}=\sqrt{3^2+4^2}=5[/tex]

All sides measure 5. So it's at least a rhombus (think of a square as a rhombus with extra restrictions).

Part b: A square has extra restriction, more important all angles being 90° and diagonals having the same length. If you discussed about slopes it's easy to see that two sides are horizontal but the other two are NOT vertical. Which might be proof enough.

But the exercise looks about lengths on the plane, so let's measure diagonals.

[tex]\overline{PA}=\sqrt{(0-2)^2+(3-(-1))^2}= \sqrt{2^2+4^2}=\sqrt{20}\\\overline{LN}=\sqrt{(5-(-3))^2+(3-(-1))^2}= \sqrt{8^2+4^2}=\sqrt{80}[/tex]

The two diagonals have different lengths, so the figure cannot be a square.

Answer:

x = 25°

Step-by-step explanation:

The angles are equal and opposite. This means that if the top angle is 150°, then the angle at the bottom must be 150° too. However, it is currently 2x° + 100°, which turns it into an equation. So far we have 100° as a known angle, so we subtract that from 150° to get the value of 2x.

2x° = 50

Now we divide 50 by 2, and that gives us 25°.

x = 25°

Step-by-step explanation:

Let x represent the third side

This is a right triangle

In right triangle the sum of square value of both legs is equal to square value of hypotenuse(the third side in this case)

Let x represent the third side

5^2 + 5[tex]\sqrt{3}[/tex]^2 = x^2

25 + 75 = x^2

100 = x^2 find the root for both sides

10 = x

Z-score of given data comes to be -5.30.

It is given that

Population mean μ= 310

Standard deviation σ= 20

Mean of sample data X= 295

Sample size n= 50

A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

For a hypothesis test

Z-score = (X-μ)/(σ/√n)

Where, X = observed value

μ= mean

σ = standard deviation

n =sample size

Z-score of above data = (295-310)/(20/√50)

Z-score = -5.30

Therefore, Z-score of given data comes to be -5.30.

Step-by-step explanation:

The value for the diamonds which would make the game of pick a diamond from a deck of 52 cards fair is 6.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

From a card at random from an ordinary deck of 52 cards is picked.If the card is a diamond, you get some points. There are total 13 diamonds in a deck of cards.

Thus, the probability of picking a diamond from 52 cards is,

[tex]P=\dfrac{13}{52}\\P=\dfrac{1}{4}[/tex]

The probability of not picking a diamond from 52 cards is,

[tex]P'=1-\dfrac{1}{4}\\P'=\dfrac{3}{4}[/tex]

If the picked card is not a diamond, then the 2 points are lost. Let X is the score in the game. If the game is fair then the expected value for this should be 0. Thus,

[tex]0=x\times \dfrac{1}{4}+2\times\dfrac{(-3)}{4}\\x=6[/tex]

Hence, the value for the diamonds which would make the game of pick a diamond from a deck of 52 cards fair is 6.

The value of i, the interest rate per period(monthly here)  that should be used in the considered formula is given by: Option B: 0.71

If we're given that:

Then, we get:

[tex]P = P_v\left(\dfrac{i}{1-(1+i)^{-n}}\right)[/tex]

For this case, we're provided that:

i = interest rate per period

And we have:

Interest rate compounding monthly = 8.5%

The interest rates are usually given for annual basis. Since i represents the rate per period, which is monthly here, thus, we will convert the rate 8.5% from annually to monthly.

Since 1 year = 12 months,

so 8.5% per year compounding monthly = (8.5/12)% per month compounding monthly

Thus, i = interest per period = interest per month = 8.5/12≈ 0.71 (in percentage)

Thus, the value of i, the interest rate per period(monthly here)  that should be used in the considered formula is given by: Option B: 0.71

A) Any positive integer is all of real, natural, integer, and rational. A couple of examples of positive integers are 2, and 3.

Any non-complex number is real: -98.6, +29.7π.

Natural numbers are positive integers: 89, 10103.

Integers are any positive or negative number that has no fractional part. Zero is also an integer. A couple are -3, 0.

A rational number is one that can be expressed as the ratio of two integers. Any finite decimal number and any repeating decimal number are rational numbers. A couple of these are 22/7 and -0.0037285.

An irrational number is a number that cannot be expressed as the ratio of two integers. A cube root of a number that is not a perfect cube will be irrational, for example, The same is true of other roots. √2, ∛-5 are irrational. Pi (π) is a famous irrational number, along with 'e', the base of natural logarithms.
