Max is the owner of California Surfer shop his store sells shortboards that are $400 he decided to have a sale for 10% off but then raised the price up by 15%, what is the price for the Shortboards?
Answer:
$414
Step-by-step explanation:
Steps to take to derive the answer to this question :
1. Determine the price after the 10% discount
2. Use the price gotten above to determine the price after the 15% raise
price after discount = original price - discount
Discount = 0.1 x $400 = $40
Price after discount = $400 - $40 = $360
Price after raise = discounted price + raise
15% raise = 0.15 x $360 = $54
Price after raise = $360 + $54 = $414
The ages of the children, in years, at a birthday party are 8, 12, 10, 9, 12, 9, 11, and 9. What is
the mean age of children at the party?
Answer:

Let X denote the time of arrival of the first vehicle from the north-south direction; let Y denote the first arrival time from the east-west direction. Time is measured in fractions of an hour after 5:30 am. Assume that the density for (X, Y ) is given by
fXY (x,y)= 1/x 0

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 134 millimeters, and a standard deviation of 8 millimeters. If a random sample of 44 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by greater than 3.6 millimeters? Round your answer to four decimal places.

=0.0028
The probability that the sample mean would differ from the population mean by greater than 3.6 millimeters is approximately 0.0014.
To determine the probability that the sample mean would differ from the population mean by greater than 3.6 millimeters, we can use the Central Limit Theorem and assume that the sample mean follows a normal distribution.
Given:
Mean diameter of the population (μ) = 134 millimeters
Standard deviation of the population (σ) = 8 millimeters
Sample size (n) = 44
Difference from the population mean (d) = 3.6 millimeters
To find the probability, we need to calculate the z-score and then find the corresponding area under the normal curve.
First, calculate the standard error of the mean (SE):
SE = σ / sqrt(n)
SE = 8 / sqrt(44) ≈ 1.206
Next, calculate the z-score using the formula:
z = (x - μ) / SE
For a difference of 3.6 millimeters, we have:
z = (3.6 - 0) / 1.206 ≈ 2.988
Using a standard normal distribution table or a calculator, we can find the area to the right of the z-score (greater than 2.988). The area represents the probability.
P(z > 2.988) ≈ 0.0014
Rounding to four decimal places, the probability that the sample mean would differ from the population mean by greater than 3.6 millimeters is approximately 0.0014.

The graphs of triangles LMN and NOP are shown.
which of the following best describes the slope of line LP?
A) 5/2
B) 2
C) 2/5
D) 1/3
===========================================================
Explanation:
Point L is located at (-8, 1) while P is at the point (7,7)
Let's apply the slope formula for these two points
m = (y2-y1)/(x2-x1)
m = (7-1)/(7-(-8))
m = (7-1)/(7+8)
m = 6/15
m = (3*2)/(3*5)
m = 2/5 is the slope of line LP
A slope of 2/5 means that each time you go up vertically 2 units (rise), you move to the right 5 units (run). In short, it's "up 2, over to the right 5". A positive slope means we move upward as we move from left to right.

Use Lagrange multipliers to prove that the rectangle with maximum area that has a given perimeter p is a square. Let the sides of the rectangle be x and y and let f and g represent the area (A) and perimeter (p), respectively. Find the following. A = f(x, y) = p = g(x, y) = ∇f(x, y) = ????∇g = Then ???? = 1 2 y = implies that x = . Therefore, the rectangle with maximum area is a square with side length .
Answer:
a) Rectangle of maximum area ( given perimeter p ) is
A= x² That means the rectangle of maximum area, is a square
Step-by-step explanation:
The equation: A (x,y) = x*y is the area of a rectangle ( to maximize)
Subject to: p = 2*x + 2*y or g(x,y) = 2*x + 2*y -p
Now
A(x,y) = x*y δA/δx = y δA/δy = x
And
g(x,y) = 2*x + 2*y -p
δg(x,y)/δx = 2 and δg(x,y)/δy = 2
Matching respective partial derivatives we get a system of equation
δA/δx = y = λ * = δg(x,y)/δx = 2
y = 2*λ
δA/δy = x = 2*λ
The system of equations is:
y = 2*λ
x = 2*λ
And 2*x + 2*y -p = 0
p = 2*x +2*y
So x = y p is equal either 4*x or 4*y
Solving for λ

Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally distributed, with a mean of 5.3 millimeters (mm) and a standard deviation of 1.1 mm. For a randomly found shard, find the following probabilities. (Round your answers to four decimal places.)
a. the thickness is less than 3.0 mm.
b. the thickness is more than 7.0 mm
c. the thickness is between 3.0 mm and 7.0 mm
Answer:
Follows are the responses to the given question:
Step-by-step explanation:
In point a:
z score for 3:
[tex]= \frac{(3 - 5.3)}{1.1} \\\\ =-2.09[/tex]
So,
P(Less than 3.0 mm):
[tex]=P(z < -2.09)\\\\ = 0.0183[/tex]
In point b:
z score for 7:
[tex]= \frac{(7 - 5.3)}{1.1} \\\\= 1.55[/tex]
So,
P(Less than 3.0 mm):
[tex]= P(z > 1.55) \\\\= 0.0611[/tex]
In point C:
P(Between 3 and 7):
[tex]= P(-2.09 < z < 1.55)\\\\\ = 0.9206[/tex]
Plsss help!! Write the equation of the line for the graph shown below.
Answer:
C. y = ½x + 4
Step-by-step explanation:
Equation for a line in slope-intercept form is given as y = mx + b
So, we need to find the slope (m) and the y-intercept (b) of the line given.
m = ∆y/∆x
Using two points on the line, (0, 4) and (-2, 3),
Slope (m) = (3 - 4)/(-2 - 0)
m = -1/-2
m = ½
y-intercept (b) = 4, this is where the line intercepts the y-axis.
To write the equation, substitute m = ½ and b = 4 into y = mx + b
Thus:
y = ½x + 4
