9514 1404 393
Answer:
real, natural, integers, rational: 2, 3irrational: √2, √3use the distributive propertyStep-by-step explanation:
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.

B) The terms inside parentheses are unlike, so cannot be combined. The only way this expression can be simplified is by removing the parentheses using the distributive property.

You pick a card at random from an ordinary deck of 52 cards. if the card is a diamond, you get some points; if not, you lose 2 points. what value for the diamonds would make the game fair? 12 6 24 3
The value for the diamonds which would make the game of pick a diamond from a deck of 52 cards fair is 6.
What is probability?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.

DOWN BELOW
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°

Which equation represents a line parallel to 2x+y=-2?
A. y=-2x+3
B. x+y=5
C. y-x=-1
D. y-2x=3
Answer:
Option A
Step-by-step explanation:
To find the answer we need to graph the following equations to see which equation is parallel to the given equation 2x + y = -2x. Your answer is option A or "y = -2x + 3." One of the biggest rules when trying to find out if the two lines are parallel to each other is seeing if the two lines intercept. In this case if you graph all the following options, the only line that does not intercept the first line 2x + y = -2 is the option A, which means it's your answer.

In calculating the monthly payment for a loan with an 8.5% interest rate compounded monthly, what value should be used for i, the interest rate per period, as it appears in the following formula? p = p v times startfraction i over 1 minus (1 i) superscript negative n endfraction a. 8.5 b. 0.71 c. 0.085 d. 0.0071
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
How to find the monthly payment?If we're given that:
[tex]P_v[/tex] = present value[tex]P[/tex] = monthly payment to be paidi = interest rate per monthn = number of periods.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

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.

Find the slope of the line through each pair of points.
1) (19,8),(-2, 11)
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
[tex]m=\frac{y2-y1}{x2-x1}[/tex]∵ 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]
