Answer:

The probability of winning a straight bet is 1/100, and the payout is $50, so the expected value of a winning bet is (1/100) * $50 = $0.50.

The probability of losing a straight bet is 99/100, and the cost of the bet is $1, so the expected value of a losing bet is (99/100) * -$1 = -$0.99.

Therefore, the expected value of a straight bet is $0.50 - $0.99 = -$0.49.

The new income is new income.

Generally, To find the new income of the man, we can use the formula: New Income = Original Income + Increase in Income

Since the ratio of increase in income is 7:8, we can assume the original income to be 7x and the new income to be 8x.

The increase in income is given as Rs. 4500 per month, so we can set up the equation as:

8x = 7x + 4500

By solving for x, we get that

x = 4500.

Therefore, the new income of the man is

8x = 8 * 4500

= Rs. 36000 per month.

b)

The ages of the two sisters are in the ratio 7:5. If the elder sister is 15 years 9 months old, we can assume her age in months to be

15*12 + 9 = 189 months.

Let's assume x be the age of younger sister in months.

So, according to the ratio 7:5, we can set up the equation as:

x = (5/12)*189

By solving this equation we get

x= 78.75 months, which is roughly 6 years and 6 months.

 (x-3)² = 12 (y – 6)  is the equation for a parabola with the vertex (3, 6) and focus (3, 9) in it.

A parabola is a U-shaped plane curve in which every point is situated at an equal distance from both the focus, a fixed point, and the directrix, a fixed line. The topic of conic sections includes parabola as a key component, and all related parabola topics are discussed. a plane curve produced by a point shifting such that its separation from a fixed point equals its separation from a fixed line: junction of a plane parallel to an element of a right circular cone with the cone. : a bowl-shaped object (such as an antenna or microphone reflector)

given

Answer:

65

Step-by-step explanation:

Method 1(Algebra):

m - 14 = 51

Add 14 to both sides of the equation.

m - 14 + 14 = 51 + 14

Combine like terms.

m = 65

Method 2:

m - 14 = 51

Move negative fourteen(- 14) to the other side of the equation. Because we moved it, it is now positive fourteen( + 14)

m = 51 + 14

Combine like terms.

m = 65

Answer:

y = 45/2

Step-by-step explanation:

Given:

y = 4x - 1 1/2

find the value of y when x=6

y = 4x - 1 1/2

Substitute x = 6 into the equation

y = 4(6) - 1 1/2

y = 24 - 1 1/2

** 1 1/2 = 3/2

y = 24 - 3/2

y = (48-3) / 2

y = 45/2

y = 45/2 when x = 6

Answer:

I think it's m=8, c=0.

Step-by-step explanation:

If c is not 0 then c=-1

Answer:

Step-by-step explanation:

Subtract the values:

In the equation y = mx + c if we substitute the value of x as zero we will get a point on the y axis given by y =(m × 0) + c ⇒ y = c. Therefore the point of the line on the y axis is (0, c) and so c is also called the y -intercept  of the line.

Now, According to the question:

i) from the general equation of line we know that any line can be represented in the form y = mx + c , where m is a constant and is called the slope of the line and c is also a constant and is the y-intercept.

ii) In the equation y = mx + c if we substitute the value of x as zero we will get a point on the y axis given by y =(m × 0) + c ⇒ y = c. Therefore the point of the line on the y axis is (0, c) and so c is also called the y intercept  of the line.

iii) If for example we have the line 3y = 6x + 12 then we first get this equation of the line to match the general form of the equation of the line, that is y = mx + c. Therefore dividing both the left and the right sides of the given equation of the line by 3 we get y = 2x + 4 which matches with the general form of the equation for line and we see that the slope of the given line is m = 2 and the y intercept is given by c = 4.

Bromine is a diatomic molecule since it is typically found in groups of two.

What is the symbol to represent a chemical compound?

An element's one- or two-letter identification is known as a chemical symbol. O for oxygen, Zn for zinc, and Fe for iron are a few instances of chemical symbols. Symbols always start with a capital letter. Lowercase letters are used for the second letter in symbols with two letters.

A subscript appears after the atom to indicate how many of each kind there are. There is no number written if there is just one atom. The number is given as a subscript after the atom if there are multiples of a particular kind of atom.

Br represents the bromine. Bromine is a diatomic molecule and always needs to be bounded to something. Thus it is bounding to itself.

3 and -3 are additive inverses because 3 + (-3) = 0.

Therefore, -3 is the additive inverse of 3.

Additive Inverse:

The additive reciprocal/ Inverse of a number is its inverse. When a number is added to the additive reciprocal, both numbers sum to zero. A simple rule is to change positive numbers to negative numbers and vice versa. We know that 3+ (-3) =0. So -3 is the additive reciprocal of 3, and 3 is the additive reciprocal of -3.

If the sum of two real numbers is 0, each real number is said to be the additive reciprocal of the other real number. Therefore, R + (-R) = 0. where R is a real number. R and -R are the additive reciprocals of each other. Example: 3/4 + (-3/4) = 0. where 3/4 is the additive reciprocal of -3/4 and vice versa. This is an example of the additive reciprocal of a fraction.

We have room temperature water in a bucket. Adding 1 liter of hot water raises the temperature of the entire bucket by a certain amount. Then add another liter of cold water. Opposite temperature water in the bucket will cancel out, resulting in a bucket of room temperature water. The same rules apply when taking the additive reciprocal of a number. The additive inverse property applies to both real and complex numbers.

x = 40°

Step-by-step explanation:

∠ FEC and ∠ ECD are same- side interior angles and sum to 180° , that is

150° + y = 180° ( subtract 150° from both sides )

y = 30°

∠ BCD and ∠ ABCare alternate angles and are congruent , so

x + y = 70° , that is

x + 30° = 70° ( subtract 30° from both sides )

x = 40°
