P(5 ≤ x ≤ 9) =
The probability P(5 ≤ x ≤ 9) is 0.6847
Assume that x has a normal distribution
We have been the mean and standard deviation μ = 6; σ = 2.
To calculate this probability we use the standardized normal distribution and the z-value for 5 and 9.
z = (5 - 6)/2
= -0.5
and z = (9 - 6)/2
= 1.5
Then the probability is calculated as:
P(x ≤ 5) = 0.3085
P(x ≤ 9) = 0.9932
P(5 ≤ x ≤ 9) = 0.9932 - 0.3085
P(5 ≤ x ≤ 9) = 0.6847
Therefore, the probability P(5 ≤ x ≤ 9) is 0.6847

3. Given the perimeter of the figure is 76 ft, Find
the dimensions of the shape.
R
(4x-5) ft
(25-x) ft
(13 + x) ft
S
T
(3x+1) ft
All the dimensions of the shape is found as 19 ft.
What is termed as the perimeter?The perimeter of any closed shape is the total length of its boundary. The total length around a shape is described as its perimeter. It is the length of any two-dimensional spatial shape's outline or boundary. Depending on the dimensions, the perimeters of irregular shapes can indeed be equal in size.For the given question, the dimensions of the shape is given as;
(4x-5) ft(25-x) ft(13 + x) ft(3x+1) ftThe perimeter of the shape = 76 ft.
The formula of the perimeter = sum of length of all sides.
Let 'P' be the perimeter.
P = (4x-5) + (25-x) + (13 + x) + (3x+1) ing
Simplifying
P = 4x - x + x + 3x - 5 + 25 + 13 + 1
76 = 7x + 34
7x = 76 - 34
7x = 42
x = 6
Thus, the dimensions of the shape is; Put x = 6
(4×6-5) ft = 19 ft(25-6) ft = 19 ft(13 + 6) ft = 19 ft(3×6+1) ft = 19 ftThus, all the dimensions of the shape is found as 19 ft.

flagpole of height 5 meters is tied to the ground by a 7 meter cable. How far from the base of the flagpole is the cable tied
We know that
• The height is 5 meters.
,• The cable is 7 meters long.
Using the given information, we can represent the situation with a diagram.
In the diagram above you can observe that the x is a leg of the right triangle. So, we have to use Pythagorean's Theorem to find x.
[tex]7^2=5^2+x^2[/tex]Then, we solve for x.
[tex]\begin{gathered} 49=25+x^2 \\ x^2=49-25 \\ x^2=24 \\ x=\sqrt[]{24} \\ x\approx4.9 \end{gathered}[/tex]Hence, the base of the flagpole is 4.9 meters from the cable, approximately.Let f(x)=2x²+x-11 and g(x)=x-1. Perform the function operation and then find the domain.

Work Shown:

The domain of each f(x) and g(x) is "set of all real numbers" since we can replace x with any real number to get some output.
By extension, this means the domain of (f+g)(x) is also "set of all real numbers".
It turns out any polynomial will have this domain. We don't have to worry about things like applying square roots to negatives, or dividing by zero. This is why there isn't a restriction on x.
To write "set of all real numbers" in interval notation, we would say [tex](-\infty, \infty)[/tex] to indicate x is anything between negative infinity and positive infinity.

if the total value of the coins is $5.50 and kayleigh has 17 quarters, how many nickels does she have?
Kayleigh have 25 nickels with her.
Given,
The total value of coins Kayleigh have = $5.50
Number of quarters with Kayleigh = 17 quarters
We have to find the number of nickels Kayleigh with her.
Lets see:
1 dollar = 4 quarters
1 dollar = 20 nickels
Here, we have a total of 5.50 dollar
In this, 17 quarters are there.
So,
17 / 4 = 4.25
That is, the value of coins as quarters is $4.25
Now,
5.50 - 4.25 = 1.25
That is,
$1.25 is in the form of nickels.
Number of nickels = 1.25 × 20
Number of nickels = 25
Therefore,
Kayleigh have 25 nickels with her.

ABC has vertices at A(4,1), B(-3,-2), and C(-1,3). what is the perimeter of ABC?
If ABC is a triangle, which when plotted on the cartesian coordinate system, has it's vertices at A(4, 1), B(-3, -2), and C(-1, 3), then the perimeter of triangle ABC will be [√58/(√2 - 1)]
As per the question statement, ABC is a triangle, which when plotted on the cartesian coordinate system, has it's vertices at A(4, 1), B(-3, -2), and C(-1, 3).
We are required to calculate the perimeter of triangle ABC.
To solve this question, first we need to calculate the distances between AB, BC ad AC, which are the three sides of our concerned triangle ABC, and then add them up to obtain our desired answer. And to calculate the lengths of AB, BC ad AC, we will need to use the distance formula which goes as,
"The distance between any two points (x₁, y₁) and (x₂, y₂) can be given by
√[(x₂ - x₁)² + (y₂ - y₁)²]
Considering points A(4, 1) and B(-3, -2), we can say that [(x₁, y₁) = (4, 1)] and [(x₂, y₂) = (-3, -2)]. Therefore, distance AB = √[{(-3) - 4}² + {(-2) - 1}²]
Or, AB = √[{-(3 + 4)}² + {-(2 + 1)}²]
Or, AB = √[(-7)² + (-3)²]
Or, AB = √[(49 + 9)]
Or, AB = √58
Similarly considering points A(4, 1) and C(-1, 3), we can say that
[(x₁, y₁) = (4, 1)] and [(x₂, y₂) = (-1, 3)].
Therefore, distance AB = √[{(-1) - 4}² + (3 - 1)²]
Or, AC = √[{-(1 + 4)}² + (3 - 1)}²]
Or, AC = √[(-5)² + (2)²]
Or, AC = √[(25 + 4)]
Or, AC = √29
Finally considering points B(-3, -2) and C(-1, 3), we can say that
[(x₁, y₁) = (-3, -2)] and [(x₂, y₂) = (-1, 3)].
Therefore, distance BC = √[{(-1) - (-3)}² + {3 - (-2)}²]
Or, BC = √[{-(1) + 3}² + (3 + 2)²]
Or, BC = √[(3 - 1)² + (5)²]
Or, BC = √[(4 + 25)]
Or, BC = √29
Therefore, the perimeter of Triangle ABC = (AB + BC + AC)
Or, perimeter of Triangle ABC = (√58 + √29 + √29)
Or, perimeter of Triangle ABC = [√(29 * 2) + √29 + √29]
Or, perimeter of Triangle ABC = [(√29*√2) + √29 + √29]
Or, perimeter of Triangle ABC = √29(√2 + 1 + 1)
Or, perimeter of Triangle ABC = √29(√2 + 2)
Or, perimeter of Triangle ABC = (√29*√2)(1 + √2)
Or, perimeter of Triangle ABC = (√58)(1 + √2)
Or, perimeter of Triangle ABC = [tex]\frac{\sqrt{58} (1+\sqrt{2})(1-\sqrt{2}) }{(1-\sqrt{2})} =\frac{\sqrt{58} [(1)^{2}-(\sqrt{2})^2 }{(1-\sqrt{2})}}[/tex]
Or, perimeter of Triangle ABC = [tex]\frac{\sqrt{58} [(1-2) }{(1-\sqrt{2})}}=\frac{-\sqrt{58}}{(1-\sqrt{2})}}=\frac{\sqrt{58}}{(\sqrt{2}-1)}}[/tex]

Kelsey starts with $150 in her account and she adds $25 a month. Kyle starts with $200 in his account and adds $20 a month to his account. Write an equation/inequality to show when Kelsey will have more money than Kyle.
Let x represents the number of months it will take Kelsey to have more money than Kyle.
Given that Kelsey starts with $150 in her account and she adds $25 a month, it means that the amount that he would have saved after x months is
150 + 25 *x
= 150 + 25x
Given that Kyle starts with $200 in his account and adds $20 a month to his account, it means that the amount that he would have saved after x months is
200 + 20 *x
= 200 + 20x
For Kelsey to have more money than Kyle, the inequality would be
150 + 25x > 200 + 20x
25x - 20x > 200 - 150

1) rewrite the formula for b
2)rewrite the formula for h
Answer:
1. b = 2A/h
2. h = 2A/b
Step-by-step explanation:
All you have to do is isolate the variable.
1.
Isolate b:
A = 1/2 x b x h
Multiply each side by 2
2A = b x h
Isolate b by dividing both sides by h
b = 2A/h
2.
Isolate h:
A = 1/2 x b x h
Multiply each side by 2
2A = b x h
Isolate h by dividing both sides by b
h = 2A/b

c) The percentage of difference between the hire purchase price and the cost price for the bicycle is 17%
Percentage:
Percentage means a fraction or a ratio in which the value of whole is always 100.
Given,
A bicycle has cash price $16,319.50. It can be bought on hire purchase with a deposit of $6,900 and ten monthly installments of $1,224.50 each.
Here we need to following:
a) Purchase price for the bicycle
b) Difference between the hire purchase price and the cost price for the bicycle
c) Percentage of the cash price.
The total purchase price is calculated by adding the deposit and the ten month installment.
So, the total purchase price is,
=> 6900 + (10 x 1224.50)
=> 6900 + 12245
=> 19145.
Therefore, the total purchase price is $19145.
Now, the difference between the hire purchase price and the cost price for the bicycle is calculated as,
=> 19145 - 16319.50
=> 2825.50
So, the difference between the hire purchase price and the cost price for the bicycle is $2,825.50
Now, we have to calculate the percentage by using the following expression,
x% of 16,319.50 = 2825.50
x% = 2825.50/16319.50
x% = 0.1731
x = 17.31.
Therefore, there is 17% difference in the hire purchase price and the cost price for the bicycle.

pick a game of chance using cards or dice and a certain outcome in that game, (such as a large straight in yahtzee, or a four of a kind in poker). explain how many ways the outcome could happen and the total number of different hands or rolls there are in that game, and show the probability of your chosen outcome.
Yahtzee is a game of chance like dice or poker. The numbers of ways the outcomes ( straight rolling ) is 240 .
Probability of hitting a large straight is 240 / 7776 = 1/32
Yahtzee is the one of dice game that uses five standard six-sided dice. After rolling each die, the player can decide which die to keep and which to reroll. Goals include many different types of combinations, many of which originate from poker.
The two types of combinations that players must roll are called roads: small roads and large roads. Similar to poker straights, these combinations consist of consecutive dice. A small straight uses 4 out of the 5 dice and a large straight uses all 5 dice. Since the dice rolls are random, we can use probability to analyze the likelihood of hitting large straight on a single roll. Assumes that the dice used are fair and independent of each other. Now, you need to know how many ways you can roll a big/ large straight. Here it is more difficult than calculating the sample size. Big straights are harder to roll than small straights, but it’s easier to count the number of times you’ve rolled a big straight than the number of times you’ve rolled a small straight.
Next, determine the number of ways to get a straight by rolling the given dice. To get a nice straight with dice {1, 2, 3, 4, 5}, you can arrange the dice in any order. It turns out that you just swap the five dice. There are 5! = 120 ways to do this. There are two dice combinations that form the large Straight, each with 120 ways to roll, so there are 2 x 120 = 240 ways to roll the large Straight.
Now the probability of hitting a big/ large straight can be calculated with simple division. Since there are 240 ways to get the big straight in one roll, and 7776 rolls 5 dice, the odds of getting the big straight are 240/7776, close to 1/32, and lie 3.1%.

[tex]\textsf{25.} \quad x=1, \quad x=-1[/tex]
Step-by-step explanation:
Question 24Given expression:
[tex]\dfrac{2}{(x-2)(x-3)}+\dfrac{2}{(x-1)(3-x)}+\dfrac{1}{(1-x)(2-x)}[/tex]
When adding rationals with different denominators, make the denominators the same by finding the least common denominator.
Create a common denominator by:
[tex]\textsf{Multiplying the first fraction by $\dfrac{x-1}{x-1}$}.[/tex]
[tex]\textsf{Multiplying the second fraction by $\dfrac{-(x-2)}{-(x-2)}$}.[/tex]
[tex]\textsf{Multiplying the third fraction by $\dfrac{x-3}{x-3}$}.[/tex]
[tex]\implies \dfrac{2}{(x-2)(x-3)} \cdot \dfrac{x-1}{x-1}+\dfrac{2}{(x-1)(3-x)}\cdot \dfrac{-(x-2)}{-(x-2)}+\dfrac{1}{(1-x)(2-x)}\cdot \dfrac{x-3}{x-3}[/tex]
[tex]\implies \dfrac{2(x-1)}{(x-1)(x-2)(x-3)}+\dfrac{-2(x-2)}{-(x-1)(x-2)(3-x)}+\dfrac{x-3}{(1-x)(2-x)(x-3)}[/tex]
[tex]\implies \dfrac{2(x-1)}{(x-1)(x-2)(x-3)}+\dfrac{-2(x-2)}{(x-1)(x-2)(-3-(-x))}+\dfrac{x-3}{(-(-1+x))(-(-2+x))(x-3)}[/tex]
[tex]\implies \dfrac{2(x-1)}{(x-1)(x-2)(x-3)}+\dfrac{-2(x-2)}{(x-1)(x-2)(x-3)}+\dfrac{x-3}{(x-1)(x-2)(x-3)}[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{d}+\dfrac{b}{d}+\dfrac{c}{d}=\dfrac{a+b+c}{d}:[/tex]
[tex]\implies \dfrac{2(x-1)-2(x-2)+(x-3)}{(x-1)(x-2)(x-3)}[/tex]
Expand the numerator:
[tex]\implies \dfrac{2x-2-2x+4+x-3}{(x-1)(x-2)(x-3)}[/tex]
[tex]\implies \dfrac{x-1}{(x-1)(x-2)(x-3)}[/tex]
Cancel the common factor (x - 1):
[tex]\implies \dfrac{1}{(x-2)(x-3)}[/tex]
Question 25Given equation:
[tex](4x-1)(x+2)=2+7x[/tex]
Expand the left side:
[tex]\implies 4x^2+7x-2=2+7x[/tex]
Subtract 7x from both sides:
[tex]\implies 4x^2+7x-2-7x=2+7x-7x[/tex]
[tex]\implies 4x^2-2=2[/tex]
Add 2 to both sides:
[tex]\implies 4x^2-2+2=2+2[/tex]
[tex]\implies 4x^2=4[/tex]
Divide both sides by 4:
[tex]\implies \dfrac{4x^2}{4}=\dfrac{4}{4}[/tex]
[tex]\implies x^2=1[/tex]
Square root both sides:
[tex]\implies \sqrt{x^2}=\sqrt{1}[/tex]
[tex]\implies x= \pm 1[/tex]
Therefore, the solutions are:
[tex]x=1, \quad x=-1[/tex]
