There are 195 natural numbers from 1 to 600

The term integer is referred as the combination of zero, natural numbers and their additive inverse

Here we need to find how many of the natural numbers from 1 to 600, inclusive, contain the digit 5 at least once.

While we looking, into the given range of numbers 100 integers from 500 - 599 contain at least one 5

And here we know that in each of the 499 integers

=> _5, _15, _25, _35, _ 45, _55 , _65, _ 75, _ 85 , _ 95

And we also know that in each hundred  from 1 to 499 contain at least one 5

Therefore, there are 5 sets of these = 5 * 10  =  50

So, in each hundred from 1 to 499 we have the  integers

Therefore, _5_   where the last digit is not a 5

So, we have 9 of these in every hundred

Then here we have  5 * 9  = 45 of these

=> 100 + 50 + 45  = 195

The number of people died from aids in U.S. in 2005 are 2,30,68,96,671

Given, diseases tend to spread according to the exponential growth model.

In the early days of aids, the growth factor (i.e. common ratio; growth multiplier) was around 1.9.

In 1983, about 1700 people in the U.S. died of aids.

we have to find the number of people died from aids in 2005.

Let the exponential function, be

P(x) = AB^x

where, A is the initial population of people died of aids in U.S.

B is the growth factor of aids in U.S.

as, B = 1.9

In 1983, x = 0

P(0) = AB^0

1700 = A

Now, P(x) = 1700(1.9)^x

and the number of years from 1983 to 2005 are, 22 years

The number of people died from aids in 2005 be,

P(22) = 1700(1.9)^22

P(22) = 2,30,68,96,671

So, 2,30,68,96,671 people died from aids in 2005.

Hence, 2,30,68,96,671 people died from aids in 2005.

Answer:

Therefore, the equation of the line that is parallel to the given line and passes through the point ( − 6 , 9 ) (−6,9) is y = 4x + 33.

Step-by-step explanation:

To find the equation of a line that is parallel to a given line and passes through a given point, you can use the point-slope form of a linear equation. The point-slope form of a linear equation is given by:

y - y1 = m(x - x1)

Where (x1, y1) is the point through which the line passes, and m is the slope of the line.

The slope of a line is given by the difference in the y-coordinates of two points on the line, divided by the difference in the x-coordinates of those points. The slope of a line is also the coefficient of the x-term in the standard form of a linear equation (y = mx + b).

In this case, the given line is x − 6y = −60 − 9x. To find the slope of this line, you can rearrange the equation to standard form:

x − 6y = −60 − 9x

−9x + x − 6y = −60

−8x − 6y = −60

y = 4x + 15

The slope of this line is m = 4.

To find the equation of a line parallel to this line that passes through the point ( − 6 , 9 ) (−6,9), you can use the point-slope form of a linear equation with (x1, y1) = ( − 6 , 9 ) (−6,9) and m = 4:

y - 9 = 4(x - (-6))

y - 9 = 4(x + 6)

y - 9 = 4x + 24

y = 4x + 33

The answer is 240 sticky hands. This is because each sticky hand costs 2 tickets, so if she has 480 tickets, she can buy 240 sticky hands.

What is cost?

Cost is the amount of money that is required to purchase, use, or produce something. It is an economic measure of the value of goods, services, or resources. Cost is typically associated with the purchase of goods and services and can include both the monetary and non-monetary costs associated with the acquisition. For example, when buying a car, the cost is the money spent on the purchase plus any additional costs such as taxes, registration fees, and insurance. Non-monetary costs can include the time and effort invested in researching and shopping for the car, as well as the opportunity cost of not using the money for something else.

Polar form of complex numbers is z=a+bi is

z = r(cosθ + i sinθ) . So, first find the absolute value of r and then argument θ. Polar form of given expression are

a) 7(√3/2 + i/2 )

b) 7(√3/2 - i/2)

c) 14(√3/2 + i/2)

d) 14(√3/2 - i/2)

The polar form of complex numbers is a different way of representing complex numbers than the orthogonal form. Complex numbers are usually represented in the form z = x+iy. where "i" is an imaginary number. But in polar form, complex numbers are represented as a combination of modulus and argument.

Problems Algebra Convert to polar form

a) 7(cos(30°) + i sin(30°))

we simplify each term.

The exact value of cos(30°) = √3/2

=> 7((√3/2) + i sin(30°))

The exact value of sin(30°) = 1/2

=> 7(√3/2 + i/2 )

Combine all values we get, 7(√3/2 + i/2 )

7(cos(330°) + i sin(330°))

Using quadrant system

b) cos(330°) = cos(360°- 30°) = cos 30° = √3/2

sin(330°) = sin(360°- 30°) = - sin 30° = -1/2

so, 7 ((√3/2) + i(-1/2))

= 7√3/2 - 7i/2 = 7(√3/2 - i/2)

c) 14(cos(30°) + i sin(30°))

= 14 ((√3/2) + i (1/2)) = 14√3/2 + 14i/2=14(√3/2 - i/2)

d) 14(cos(330°) + i sin(330°))

= 14 (√3/2) + 14i(-1/2) = 14√3/2 - 14i/2

= 14(√3/2 - i/2)

The sum of all scores' squared deviations from the mean is lower than the sum of all scores' squared deviations from any other number. The least squares concept governs this.

What is Mean ?

The average of a group of values is referred to as the mean. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

The term "mean square" refers to the sample variance in the analysis of variance (ANOVA) table, which calculates the mean squared deviation.

The equation part of the given word problem is x+y=52 and y=x+16.

a) Let x = number of green eyed dolls

And let y = number of blue-eyed dolls

Now we are told the following:

x+y=52 → eq1

and

y=x+16 → eq2

b) substitute y = x+16 from eq2 into eq1:

x+x+16 = 52 subtract 16 from each side

x+x+16-16 = 52-16 collect like terms

2x = 36 divide each side by 2

x = 18 → number of green-eyed dolls

substitute x = 18 into equation2

y = 18+16 =34 → number of blue-eyed dolls

18+34=52

52=52

and

18+16=34

34=34

THIS PROBLEM CAN ALSO BE SOLVED USING ONE EQUATION AND ONE UNKNOWN:

Let x = Number of green-eyed dolls

Then 52-x = Number of blue-eyed dolls

Now we are told that:

We have a 1/6 chance of rolling doubles on the first roll. The odds of rolling a double on the second turn but not the first are (5/6) x (1/6) = 5/36.

So we have a total of 36 outcomes over here. So we have 36 possibilities, and if we simplify this, 6/36 is 1/6. So the chance of rolling doubles on two six-sided dice numbered 1 to 6 is 1/6.

The odds of rolling a double on the second turn but not the first are (5/6) x (1/6) = 5/36.

Cost of another 3 panes of class is 7.95

Given, Number of panes of glass bought = 8

Cost of 8 panes of glass = $21.20

Number of broken panes of glass = 3

We must determine the price of three glass panes.

By unitary method, If 8 panes of glass costs $21.20 , then the cost of one pane of glass will be as follows,

Cost of one pane of glass = 21.20/8

                                            = $2.65

Therefore,  cost of  3 panes of glass it would be $2.65×3 = 7.95

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.

The area for the triangle whose perimeter and side is given is solved by the formula

A= √(s(s ﹣ a) (s ﹣ b) ( s ﹣ c))

where:

a, b, and c are the sides of the triangle

s = perimeter / 2

perimeter = a + b + c

10.5 = 4.5 + 1 + c

c = 10.5 - 5.5

c = 5

s = (a + b + c) /2

s = 10.5/2
