Find P(5.5 ≤ X ≤ 7.5) where x is normally distributed with mean μ = 2.6 and standard deviation σ = 2.2
Therefore, the probability that X is between 5.5 and 7.5 is approximately 0.0808.
An illustration of a distribution is what?If a company creates apparel and sells it to people directly through an online site, it may be using direct distribution.
To solve this problem, we need to standardize the distribution of X to a standard normal distribution. This is done using the following formula:
Z = (X - μ) / σ
where Z is the standard normal variable, X is the normally distributed variable, μ is the mean of X, and σ is the standard deviation of X.
Using the given values, we have:
Z1 = (5.5 - 2.6) / 2.2 = 1.318
Z2 = (7.5 - 2.6) / 2.2 = 2.682
We can then find the probability using the standard normal distribution table or a calculator with a built-in normal distribution function.
Using the table or calculator, the probability is:
P(5.5 ≤ X ≤ 7.5) = P(1.318 ≤ Z ≤ 2.682) = 0.0808 (rounded to four decimal places)
Therefore, the probability that X is between 5.5 and 7.5 is approximately 0.0808.

Step-by-step explanation:
Francine has cut a piece of paper into a triangle but did not make a perpendicular cut find the area of piece of paper to the nearest tenth of a square centimeter
Answer: Without a perpendicular cut, we cannot determine the height of the triangle directly. However, we can use the Pythagorean Theorem to find it indirectly.
Let's assume that Francine has cut the paper into a right triangle ABC, where AB and BC are the legs of the triangle, and AC is the hypotenuse. Let x be the length of AB and y be the length of BC. We can then use the Pythagorean Theorem to find the length of AC:
AC^2 = AB^2 + BC^2
We don't know the exact values of AB and BC, but we do know that the area of the triangle is given by:
Area = (1/2) * AB * BC
We can use this formula to find the area in terms of x and y:
Area = (1/2) * x * y
Now we need to eliminate one of the variables (either x or y) so that we can express the area in terms of the other variable and AC. We can do this by rearranging the Pythagorean Theorem to solve for one of the variables:
x^2 = AC^2 - y^2
y^2 = AC^2 - x^2
Let's solve for y:
y^2 = AC^2 - x^2
y = sqrt(AC^2 - x^2)
Now we can substitute this expression for y into the formula for the area:
Area = (1/2) * x * sqrt(AC^2 - x^2)
To find the maximum possible area, we need to maximize this expression. We can do this using calculus, by taking the derivative of the expression with respect to x, setting it equal to zero, and solving for x. However, since we only need an approximate answer to the nearest tenth of a square centimeter, we can use trial and error to find the value of x that gives the maximum area. We can start by trying different values of x, and using a calculator to evaluate the expression and find the corresponding area.
Let's try a few values of x:
If x = 0, then the area is 0.
If x = AC/2 (i.e., if the triangle is isosceles), then the area is (1/8) * AC^2 * sqrt(3), which is approximately 0.433 * AC^2.
If x = AC/sqrt(3) (i.e., if the triangle is equilateral), then the area is (1/4) * AC^2 * sqrt(3), which is approximately 0.433 * AC^2.
Since the area is maximized when the triangle is equilateral, we can assume that the piece of paper is an equilateral triangle, and use the formula for the area of an equilateral triangle:
Area = (sqrt(3)/4) * side^2
where side is the length of one of the sides of the triangle. To find the side length, we need to know the length of AC. We don't know the exact value of AC, but we can estimate it by measuring the length of the longest side of the piece of paper (assuming that it is the hypotenuse of the triangle). Let's say that the longest side is 30 cm. Then, by the Pythagorean Theorem, we can find the length of the other two sides:
x^2 + y^2 = 30^2
x^2 + (sqrt(AC^2 - x^2))^2 = 30^2
2x^2 + AC^2 - x^2 = 900
x^2 = (900 - AC^2)/

Tell whether the ordered pair is a solution of the equation.
7=y-5× (4,28)
Answer: No
Step-by-step explanation:
So you have to substitute the x and y with the numbers in the ordered pair.
y becomes 28.
x becomes 4.
So the equation 7 = y - 5x becomes 7 = 28 - 5(4).
Then, you solve.
7 = 28 - 5(4)
7 = 28 - 20
7 = 8
7 ≠ 8
So, the ordered pair is NOT a solution of the equation.

You go into a car dealership and tell them that you have a budget of $300/month. You are interested in getting a Chevy Cruze that is on sale for $16,000. Due to your excellent credit score, you qualify for a 5-year loan at 4% APR with No Down Payment. What is your monthly payment? Are you within budget?
how much will the car cost you after the loan has been paid in full?
Answer: $17,788.20
Step-by-step explanation:
To calculate the monthly payment, we can use the loan formula:
P = (r * A) / (1 - (1 + r)^(-n))
where:
P is the monthly payment
A is the loan amount, which is the sale price of the car ($16,000) in this case
r is the monthly interest rate, which is the annual percentage rate (APR) divided by 12 (4% / 12 = 0.003333...)
n is the total number of payments, which is the number of years of the loan multiplied by 12 (5 years * 12 = 60)
Substituting these values into the formula, we get:
P = (0.003333... * $16,000) / (1 - (1 + 0.003333...)^(-60))
P ≈ $296.47
Therefore, the monthly payment is approximately $296.47, which is within the budget of $300/month.
To calculate the total cost of the car after the loan has been paid in full, we can multiply the monthly payment by the total number of payments (60) and add the original sale price of the car:
Total cost = P * n + A
Total cost = $296.47 * 60 + $16,000
Total cost = $17,788.20
Therefore, the total cost of the car after the loan has been paid in full is approximately $17,788.20.
The length of a rectangular poster is 8 more inches than two times its width. The area of the poster is 42 square inches. Solve for the dimensions (length and width) of the poster.
The dimensions of the poster are approximately 10.64 inches by 1.15 inches.
What are dimensions of an objects?
Dimension is the length or width of an area, region, or space in one direction. It is just the measurement of an object's length, breadth, and height.
According to the problem, the length of the poster is 8 more inches than two times the width, which can be expressed as:
length = 2x + 8
The area of the poster is given as 42 square inches, so we can set up the equation:
area = length * width
Substituting the expressions for length and width, we get:
42 = (2x + 8) * x
Expanding the right side, we get:
[tex]42 = 2x^2 + 8x[/tex]
Moving all terms to one side, we get:
[tex]2x^2 + 8x - 42 = 0[/tex]
Dividing both sides by 2, we get:
[tex]x^2 + 4x - 21 = 0[/tex]
We can solve for x using the quadratic formula:
x = (-4 ± √(4² - 41(-21))) / (2*1)
x = (-4 ± √88) / 2
x = (-4 ± 2√22) / 2
x = -2 ± √22
Since the width of the poster cannot be negative, we take the positive solution:
x = -2 + √22
Using this value, we can find the length of the poster:
length = 2x + 8 = 2(-2 + √22) + 8 = 2√22 + 4
Therefore, the length of the poster is approximately 10.64 inches (rounded to two decimal places).
Thus, the dimensions of the poster are approximately 10.64 inches by 1.15 inches.

A photocopier enlarges in the ratio 7:4 what would be the new size of a diagram measuring 16 cm and 12cm?
Answer:
The new size of the diagram would be 28 cm by 16.8 cm. This is calculated by multiplying the original dimensions of 16 cm and 12 cm by the ratio of 7:4. Therefore, the new width of the diagram would be 16 cm x 7 = 112 cm and the new height would be 12 cm x 4 = 48 cm. The new size of the diagram is therefore 112 cm by 48 cm, which can be simplified to 28 cm by 16.8 cm
Step-by-step explanation:
A photocopier that enlarges in the ratio 7:4 will increase the size of the diagram by a factor of 7/4. To find the new size of the diagram, we can multiply the original measurements by the factor of enlargement.
The new width of the diagram will be:
16 cm × 7/4 = 28 cm
The new height of the diagram will be:
12 cm × 7/4 = 21 cm
Therefore, the new size of the diagram will be 28 cm by 21 cm.
Answer: The new size of the diagram will be 28 cm by 21 cm.

Elijah currently has $800.00 in the bank account, how much
interest has he earned?
The amount of interest he has earned is $438
What is compound interest?Compound interest is the interest you earn on interest. This can be illustrated by using basic math: if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.
A = P ( 1+r/100) ^t
