One high speed Internet provider has a $39 setup fee and charges $40 per month. Another
provider has a $60 setup and charges $30 per month. In how many months will the cost be the
same?
Answer:
2.1 months
Step-by-step explanation:
Let x represent the number of months
Set up expressions to represent the cost of each Internet provider
40x + 39 will represent the first one
30x + 60 will represent the other
Set these equal to each other and solve for x:
40x + 39 = 30x + 60
10x + 39 = 60
10x = 21
x = 2.1
So, the cost will be the same in 2.1 months

uppose you select a random card from a standard deck of
52
cards and no jokers. If you draw a face card (king, queen, or jack), you win
$5
. If you draw an ace, you win
$20
. If you draw any other card, you lose
$2
. What is the expected profit from any one draw?
Answer:
The value is [tex] E(k) = \frac{68}{52}[/tex]
Step-by-step explanation:
From the question we are told that
The total number of cards is [tex]n = 52[/tex]
Let k represent the winnings and loss when any card is drawn
So k = $5 when a faced card is drawn
So k= $ 20 when an Ace card is drawn
So g = - $2 when any other card is drawn
Generally in a standard deck of card
The number of Ace is 4
The number of queen is 4
The number of jack is 4
Therefore the number off faced cards is
R = 4 + 4 + 4 = 12
Generally the number of other cards is
Y = n - R
=> Y = 52 - 12
=> Y = 36
Generally the probability of drawing a faced card is mathematically represented as
[tex]P(k = 5) = \frac{ 12}{52}[/tex]
Generally the probability of drawing a Ace card is mathematically represented as
[tex]P(k = 20) = \frac{ 20}{52}[/tex]
Generally the probability of drawing a other card is mathematically represented as
[tex]P(k = -2) = \frac{ 36}{52}[/tex]
Generally the expected profit from any one draw is mathematically represented as
[tex]E(k) = \sum k_i * P(K = k)[/tex]
=> [tex]E(k) = 5 * \frac{ 12}{52} + 20\frac{ 20}{52} + [- 2 * \frac{ 36}{52}][/tex]
=> [tex] E(k) = \frac{68}{52}[/tex]

If there are 6 grams of fat in a snack how many grams of protein are there?
6 grams of fat in a snack then 50 grams of protein in snacks
The required amount of protein cannot be specified for the snack which has 6 grams of fat.
To determine If there are 6 grams of fat in a snack how many grams of protein are there.
Statistics is the study of mathematics that deals with relations between comprehensive data.
Here,
The composition of fat is given since the data is not given.
Proper static data is required to conclude the amount of protein for the corresponding amount of 6 grams of fat, so the amount of protein cannot be specified for the snack which has 6 grams of fat.
Thus, the required amount of protein cannot be specified for the snack which has 6 grams of fat.

Answer:
a) A = {-3, -2, -1}
b) n(A) = 3
c) A is finite
Step-by-step explanation:
a) The elements of A are the integers between -4 and 0, not including those values. Those integers are -3, -2, -1, so those are the elements of set A.
A = {-3, -2, -1}

The perimeter and area of a rectangle with a length of 10 have the same numerical value. What is the width of the rectangle?
Answer:
b=2.5
Step-by-step explanation:
We know that,
Area of a rectangle= Length X Breadth
Perimeter of a rectangle= 2( Length + Breadth)
From the provided information we get that,
Area= Perimeter
lb=2(l+b)
Substituting l=10,
10b=2(10+b)
10b=20+2b
10b-2b=20
8b=20
b=20/8
b=2.5

Find the sum of the reciprocals of two consecutive even integers if the larger integer is x. please answer;-;
Step-by-step explanation:
Let the larger integer be x
Hence, the smaller integer = x-2
Hence,
Reciprocal of the x= 1/x
Reciprocal of x-2= 1/ x-2
Hence. their sum=
[tex] \frac{1}{x} + \frac{1}{x - 2} \\ = \frac{x - 2 + x}{x(x - 2)} \\ = \frac{2x - 2}{ {x}^{2} - 2x} [/tex]
The sum of the reciprocals of two consecutive even integers if the larger integer is [tex]x[/tex] is [tex]\frac{2}{x}[/tex].
For two consecutive even integers, if the larger integer is [tex]x[/tex], then the smaller one is [tex]x-2[/tex].
Their reciprocals will be [tex]\frac{1}{x}[/tex] and [tex]\frac{1}{x-2}[/tex].
Now, the sum of the reciprocals is [tex]\frac{1}{x} + \frac{1}{x-2}[/tex]
[tex]= \frac{1}{x} + \frac{1}{x-2}[/tex]
[tex]= \frac{x-2+x}{x(x-2)}[/tex]
[tex]= \frac{2x-2}{x(x-2)}[/tex]
[tex]= \frac{2(x-2)}{x(x-2)}[/tex]
[tex]= \frac{2}{x}[/tex]
So, the sum of the reciprocals of two consecutive even integers if the larger integer is [tex]x[/tex] is [tex]\frac{2}{x}[/tex].

Answer:
82/99
Step-by-step explanation:
1. Notice the length of the repeating pattern.
the pattern is 82 repeating, a 2-digit pattern
2. Notice where the repeating pattern starts, relative to the decimal point.
the repeating starts at the decimal point
3. If the repeating starts at the decimal point, use a pattern of repeating 9s of the same length as the denominator of the fraction
2 nines are the denominator: 82/99
4. Reduce the fraction if possible
this fraction cannot be reduced
As a simplified fraction, 0.828282... = 82/99
_____
Comment on more complicated cases
If the repeat does not start at the decimal point, or if the number contains an integer part, then the numerator of the fraction is found in a slightly different way. Let n be the number of repeating digits of the number x. The fraction is then ...
(10^n·x -x)/(10^n -1)
Example:
1.2345345345... a number with a 3-digit repeat not starting at the decimal point
(1234.5345... -1.2345...)/(1000 -1) = 1233.3/999 = 4111/3330
The multiplication by 10^n aligns the repeating parts so they cancel when you do the subtraction.

Answer:
544 units²
Step-by-step explanation:
The surface area is the sum of the areas of the three rectangular faces and the two triangular bases.
SA = 10×14 +10×14 +12×14 + 2(1/2)(12)(8)
= 14×(10+10+12) +12×8
= 448 +96
= 544 . . . . square units
_____
The area of a rectangle is the product of its dimensions:
A = LW
The area of a triangle is half the product of its base and height:
A = (1/2)bh
Here, both triangles have the same area, so we multiplied the area of one of them by 2 to get the area of both of them.
