A passbook savings account has a rate of 10% Find the effective annual yield if the interest is compounded daily.
Answers
The effective annual yield if the interest is compounded daily is 10.5155 %.
The annual interest rate or rate of return that an investor is entitled to over a particular time period is known as effective annual yield.
In the case of daily, there are 360 days in a year.
Therefore, making n = 360.
Therefore, the effective annual yield if the interest of 10% is compounded daily when r = 10 % and n = 360 will be:
Y = ( 1 + r/n )ⁿ - 1
Y = ( 1 + 0.1 / 360 )³⁶⁰ - 1
Y = ( 1 + 0.000277 )³⁶⁰ - 1
y = 1.105155 - 1
Y = 0.105155
However, since it is in decimal form, we must first multiply it by 100 before adding the symbol "%" after the last digit of the value.
Therefore,
Y = 0.105155 × 100%
Y = 10.5155 %
Therefore, the effective Annual Yield is 10.5155 %

a gear reduction drive has three separate stages with ratio of 3:1,2.38:1 and 4.2:1. the total ratio of the drive is?
Answers
The total ratio of the drive is 9.58:1.
What are ratios?A relationship between two quantities that are typically stated as the product of their respective quotients is known as a ratio.The ratio formula is given as a:b = a/b for any two quantities, let's say a and b.Given ratios of the three separate stages of a gear reduction drive are 3:1,2.38:1 and 4.2:1.
To find the total ratio of the drive we have to add the respective ratios.
When the denominator of the ratios are same, as in this case we just have to add the numerators to obtain the result.
Total ratio of the drive = 3:1 + 2.38:1 + 4.2:1 = 9.58:1
So, the total ratio of the drive is 9.58:1.

What is (-5,2); m=2/5 in standard form?
Answers
The standard form of the straight line is given by 5y - 2x = 20 .
Ax + By = C is the standard form for two-variable linear equations.
Standard form is used, for instance, in the linear equation 6x+5y=11. This method makes finding an equation's two intercepts very simple (x and y) .Y = mx + c is the cartesian equation for a straight line, where m denotes the gradient of the line and c denotes the location of its y-axis intersection.An infinitely long object without any width, depth, or curvature is a line. Since they can exist in two, three, or higher dimensions, lines are one-dimensional objects.We know that when a straight line passes through (a,b) with slope m then the equation of the line is given by:
y - b = m ( x - a )
putting the values in the respective places we get:
y - 2 = 2/5 × ( x + 5 )
or, 5y - 10 = 2x + 10
or , 5y - 2x = 20
Hence the standard form of the straight line is given by

In a lottery game, a player picks six numbers from 1 to 21. if the player matches all six numbers they win 50,000 dollars otherwise they lose $1

Your best option is to simply choose six distinct numbers, in any sequence. You would win if those six numbers matched the six that the lottery officials chose (again, in any sequence).
The likelihood of selecting the correct six numbers is one in
[tex]\frac{23}{6}[/tex] = [tex]\frac{23}{6(23-6)}[/tex] = [tex]\frac{23.22.21.20.19.18}{1.2.3.4.5.6}[/tex] = 100974
Therefore, 100946/100947, or a probability of losing, is very near to 1.
The total of your payouts multiplied by the probability that each scenario will occur is the anticipated value of the game. which is
(50,000) [tex]\frac{1}{100947}[/tex] + (-1) [tex]\frac{100946}{100947}[/tex] = [tex]\frac{50000-100946}{100947}[/tex] = -0.5046

Answers
Probability of randomly selecting two members who currently hold positions of chairman and ranking member and reassigning them to their current positions from a committee of 14 members is (1 /182).
As given,
Total members in the committee=14
Number of members serve as chairman and ranking member=2
Total number of ways to assigned new position
=¹⁴P₂
=(14!) / (14-2)!
=(14 × 13 × 12!) / 12!

Each member is equally likely to serve in any of positions.
Each position there is only one way to reassign position.
Probability of randomly selecting two members = 1 /182

The first four terms of the binomial series are 1, x, - x²/2 and - 1/32x³ respectively.
The binomial provided to us is [tex](1+2x)^{1/2}[/tex]
To find out the first four terms of the binomial, we shall first extend the standard binomial (1+x)^n.
(1+x)^n = 1 + nx + [n(n - 1)/2!] x² + [n(n - 1)(n - 2)/3!] x³ +...
As we can see here,
The value of x = 2x,
The value of n = 1/2.
We get,
(1+2x)^1/2 = 1 + 1/2(2x) + [1/2(1/2-1)/2!]x² + [1/2(1/2-1)(1/2-2)/3!]x³ +
(1+2x)^1/2 = 1 + x - x²/2 - 9/4x³ + .....

First term = 1
Second term = x
Third term = -x²/2
Fourth term = -1/32x³.
