Answers
Answer: a = 0.98
Explanation: For this case we have the following table:
x | P(x)
0| 0.1296
1| 0.3456
2| 0.3456
3 | 0.1536
4| 0.0256
We can find the expected value as:
E(X)= 0*0.1296 + 1*0.3456+ 2*0.3456+ 3*0.1536+ 4*0.0256= 1.6
Now we can find the second moment like this:
E(X^2)= 0^2*0.1296 + 1^2*0.3456+ 2^2*0.3456+ 3^2*0.1536+ 4^2*0.0256= 3.52
And the variance is given by:
Var(X)= E(X^2)- [E(X)]^2 = 3.52 -(1.6^2)=0.96
Then the standard deviation is:
Sd(X)= sqrt(0.96)=0.98

The perimeter of a rectangle is at least 32 cm. The length of the rectangle is 9 cm. What are the possible widths of the rectangle? Show your work.
Answers
Answer:7 on both sides all together 14
Step-by-step explanation:32 is length and width combined so 18 all together for width which leaves 14 cm for width so both sides are 7
Answer:
width ≥ 7 cm
Step-by-step explanation:
The perimeter formula is ...
P = 2(L +W)
We have P ≥ 32 and L = 9. We want to find W. (Dimensions are cm.)
2(9 +W) ≥ 32 . . . . substitute for P and L
2W ≥ 14 . . . . . . . subtract 18 and simplify
W ≥ 7 . . . . . . . . . divide by 2
Possible widths are at least 7 cm.

Use the table to determine the total amount paid on a 20 year fixed loan, at 5.5%, of $160,000. A 5-column table with 4 rows titled Monthly Payments per 1000 dollars of mortgage. Column 1 is labeled Interest Rate (percent) with entries 5, 5.5, 6, 6.5. Column 2 is labeled 10 Years with entries 10.61, 10.86, 11.11, 11.36. Column 3 is labeled 20 years with entries 6.60, 6.88, 7.17, 7.46. Column 4 is labeled 30 years with entries 5.37, 5.68, 6.00, 6.33. Column 5 is labeled 40 years with entries 4.83, 5.16, 5.51, 5.86. a. $160,000 c. $264,192 b. $203,254 d. $176,000 Please select the best answer from the choices provided A B C D Mark this and return
Answers
Answer:
c. $264,192
Step-by-step explanation:
Column 3, labeled 20 Years, would be the column you want for a 20-year loan.
Row 2, labeled 5.5%, would be the row you want for a 5.5% loan.
The value in the table at row 2 of column 3 appears to be 6.88. The is the amount of the payment per $1000 of loan value. A $160,000 loan will have a monthly payment that is 160 times $6.88 = $1100.80.
The 20-year loan will be paid back with 20×12 = 240 monthly payments. The total amount of those payments will be ...
240×$1100.80 = $264,192

Answer:
(a) $254.08
(b) $767.34
(c) $12,449.36
Step-by-step explanation:
These questions are best answered by a financial calculator or app. Such are available for your phone or tablet. A spreadsheet also has built-in functions for making these calculations.
(a) FV = $40,000, i = 8% per year, n = 9 years (108 months), compounding 12 times per year. The monthly deposit needs to be $254.08.
__
(b) Payment = $254.08, n = 3 months, i = 8%/year, compounding 12 times per year. FV = $767.34.
__
(c) The sum of 108 payments of $254.08 is ...
108 × $254.08 = $27,440.64
The interest earned is enough to bring the account value to $40,000, so is ...
$40,000 -27,440.64 = $12,559.36
_____
Additional comment
The amount $254.08 is rounded down to the nearest cent, so the balance after 9 years will be $39,999.70, which is $0.30 short of $40,000. We used $40,000 as the final account balance, so overestimated the interest by $0.30.
There may be additional small changes in the values if you round interest to the nearest cent each month the way a financial institution would. It is hard to tell in these problems how accurate you're intended to be in your calculations.

[tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\frac{2}{1}}[/tex]
Step-by-step explanation:
The mathematical operation of division is the opposite of multiplication. When you divide two fractions, you will have to take the reciprocal of the divisor, and multiply it with the dividend.
In the given equation, [tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\:?}[/tex], we can rewrite this as: [tex]\mathsf{\frac{4}{3} \:\div\:?\:=\:\frac{4}{3} \:\times\frac{1}{2}}[/tex].
As previously mentioned, division is opposite of multiplication. Since the multiplicand in the multiplication of two fractions is ½, then we can assume that the divisor (or the missing fraction) must be the reciprocal of ½, which is [tex]\mathsf{\frac{2}{1}\:or\:2}[/tex].
Therefore, the missing fraction that completes the given mathematical statement is [tex]\mathsf{\frac{2}{1}\:or\:2}[/tex].
[tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\frac{2}{1}}[/tex]

Answers
Answer:
Step-by-step explanation:
A translation 5 units down followed by a 180-degree counterclockwise rotation about the origin
Step-by-step explanation:
The figure is obviously rotated 180°. If the rotation is first, the image would be in the 4th quadrant, where it would stay after translation downward.
If the translation is downward first, it would be in the 3rd quadrant, moving to the first quadrant after rotation by 180°. This is the apparent sequence of transformations:

Step-by-step explanation:
8x² -16 -28x , rearrange it so the exponents will be going form highest to lowest
8x²-28x -16, factor 4
4(2x² -7x -4),
to get 2x² we need to multiply an x and a 2x
to get -4 we need to multyply 1 and -4 or -1 and 4 or 2 and -2 (can use trial and error method here)
4(x -4)(2x +1)

4(x-4)(2x+1) = (4x -16)(2x+1) = 8x² +4x -32x -16 = 8x²-28x -16

10 • 16 + 5 and (10 • 16) + 5 are equivalent.
Answers
Answer:
These two equations are equivalent because the order of operations states you work from the right to the left and do the multiplication first. Because we do the multiplication first, we get the same answer as the other equation because the parentheses are also done first, meaning these equations both get the same answer.
Step-by-step explanation:
What should be the first step to solve the equation?
2x + 9(x - 1) = 8(2x + 2) - 5
O Combine like terms on each side of the equation.
O Use the distributive property on each side of the equation.
Use the subtraction property of equality to subtract 5 from each side of the equation.
Use the addition property of equality to add 2x to each side of the equation.
Answers
Answer:
Your answer would be to Use the distributive property on each side of the equation.
Step-by-step explanation:
You would first expand the equation by using the distributive property on each side of the equation
[tex]2x + 9(x - 1) = 8(2x + 2) - 5\\2x + 9(x) 9(-1) = 8(2x) 8(2) - 5\\2x + 9x-9 = 16x+16 - 5[/tex]
Then you would combine like terms on both sides
[tex]2x+9x-9=11x-9\\16x+16-5=16x+11[/tex]
Now you solve for x
[tex]11x-9=16x+11[/tex]
You subtract 11x from both sides
[tex]11x-9=16x+11\\-11x=-11x[/tex]
Then you subtract 11 from both sides
[tex]-9=5x+11\\-11=-11[/tex]
Then you divide 5 on both sides
[tex]-20=5x[/tex]
[tex]\frac{-20}{5} =\frac{5x}{5}[/tex]
[tex]x=-4[/tex]

Step-by-step explanation:
For x=10, the marked angles are ...
(7x-5)° = (70 -5)° = 65°
(10x +15)° = (100 +15)° = 115°
(12x -5)° = (120 -5)° = 115°
(8x -25)° = (80 -25)° = 55°
We notice that the alternate interior angles between lines c and d are congruent, so those lines are parallel. The acute angle at line b is supplementary to the obtuse angle at lines c and d, so line b is parallel to those two lines, as well.
The angle at line e is not related to any of the other angles, so that line is not parallel to any of the others shown.

Answers
Answer:
Depends on the value of x. If x = 3, the triangle has sides 18, 6, 16 which satisfies the triangle inequality, so 2x+12 is longest in this case. If x is very large, the triangle inequality is still satisfied, and 6x-2 is the longest side.
