Total estimateGiven data or information :
Product = ( – 25. 31 ) (9. 61)
Now let estimate the product by first approximating the product to the nearest tenth.
Approximation :
So,
-25.31 = - 25 ( Approximately )

Find the first four terms of the binomial series for the function (1+2x)^1/2
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 + .....
From the expansion, we can see,
First term = 1
Second term = x
Third term = -x²/2
Fourth term = -1/32x³.

529 One digit is right, but in the wrong place
Answer:
987
Step-by-step explanation:
You want to determine a three-digit combination based on clues about which digits are right and/or correctly placed.
Clue 1This tells you one of digits 1, 2, or 7 is correct and correctly placed.
Clue 2 tells you that digit is not 1. Clue 4 tells you that digit is not 2.
7 is correctly placed as the 3rd digit
Clue 2We already know that 1 is not the correct digit. This means 3 must be the first digit, or 8 must be the first or second digit.
Clue 3We already know that 7 is a correct digit, properly placed as the 3rd digit. Since 1 is not a correct digit, 9 must be a correct digit, properly placed as the 1st digit.
9 is correctly placed as the 1st digit
Combining this fact with Clue 2 means ...
8 is correctly placed as the 2nd digit
The combination is 987.

What is (-5,2); m=2/5 in standard form?
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

optionsWe want to obtain an expression equivalent to 8 using these symbols and numbers.
The option that exactly matches this is,

7 divided by 7 is 1.
1 squared is still one, and;
1 added to 7 is 8.
So one answer is option D.

Which is;

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

You should play the game if it is more than zero because you will typically win, and you shouldn't play it if it is less than zero because you will typically lose.
