The list price of a camera was w dollars. Dylan bought the camera for $35 less than the
list price. If the sales-tox was 8%, how much did Dylan pay for the comers including the
sales tax
Answer:
$(1.08)(w-35)
Step-by-step explanation:
The list price of the camera is w dollars.
Dylan bought the camera for $35 less than the list price, so the price he paid before tax is (w - 35) dollars.
The sales tax is 8%, which can be expressed as a decimal by dividing by 100: 8/100 = 0.08.
To find the amount of sales tax, multiply the price before tax by the tax rate: (w - 35) * 0.08.
Add the sales tax to the price before tax to find the total amount Dylan paid: (w - 35) + (w - 35) * 0.08.
Factor out (w - 35) to simplify the expression: (1 + 0.08)(w - 35).
Calculate 1 + 0.08 = 1.08.
The final expression for the amount Dylan paid, including sales tax, is (1.08)(w - 35) dollars.

IQ tests are standardized and follow a normal distribution. On a common IQ test, the mean score is 100 with a standard deviation of 15. a) What is the probability that a randomly selected individual gets a score of 105 or higher
Given, On a common IQ test, the mean score is 100 with a standard deviation of 15To find, The probability that a randomly selected individual gets a score of 105 or higher Solution: Standard score can be calculated as z = (X - μ) / σwhere X is the raw score, μ is the mean, σ is the standard deviation z = (105 - 100) / 15z = 0.3333
Probability (p) of z can be calculated as: p = P(Z > 0.3333)We know that the standard normal distribution is symmetrical. Hence the area to the right of the mean is equal to the area to the left of the mean plus mean itself is 0.5.P(Z > 0.3333) = 0.5 - P(Z < 0.3333)Using standard normal distribution table, the value of P(Z < 0.3333) = 0.6293P(Z > 0.3333) = 0.5 - P(Z < 0.3333)= 0.5 - 0.6293= -0.1293
Since probability cannot be negative, the answer is 0. Hence the probability that a randomly selected individual gets a score of 105 or higher is 0. The probability that a randomly selected individual gets a score of 105 or higher is 0.More than 100 words: An IQ test is intended to determine a person's intelligence. Standardizing IQ tests allows comparison of scores from different IQ tests. A normal distribution is a bell-shaped curve where most values lie near the mean value. This means that, if a test follows a normal distribution, most people score close to the mean, with fewer scoring at the lower and higher ends. On a common IQ test, the mean score is 100, and the standard deviation is 15. A standard score (z-score) is calculated by subtracting the mean from a raw score and dividing by the standard deviation. The formula for calculating z-score is: z = (X - μ) / σFor instance, to calculate the z-score of a person who scores 105, the z-score formula is: z = (105 - 100) / 15 = 0.3333The standard normal distribution table can be used to look up the probability of a z-score being higher or lower than a particular value. In this case, we want to find the probability of a score of 105 or higher. Therefore, we need to find the area to the right of the z-score of 0.3333.

Consider the functions f(x) = 3x², g(x)=3, and h(x) = 3x.
Which statements accurately compare the domain and range of the functions? Select two options.
All of the functions have a unique range.
The range of all three functions is all real numbers.
The domain of all three functions is all real numbers.
The range of f(x) and h(x) is all real numbers, but the range of g(x) is all real numbers except 0.
The domain of f(x) and h(x) is all real numbers, but the domain of g(x) is all real numbers except 0.
The statements that accurately compare the domain and range of the functions are: The domain of all three functions is all real numbers, The range of f(x) and h(x) is all real numbers, but the range of g(x) is all real numbers except 0.
The domain of a function refers to all the possible input values that make the function defined. For the quadratic function f(x) = 3x², there are no values of x that make the function undefined, so the domain of f(x) is all real numbers. To find the range of f(x), we can calculate the vertex of the parabola, which is (0,0). The range of f(x) is all real numbers greater than or equal to zero.
For the quadratic function f(x) = 3x², we can determine the vertex using the formula:
h = -b/2a
In this case, a = 3 and b = 0, so:
h = -0/2(3) = 0/6 = 0
The x-coordinate of the vertex is 0.
To find the y-coordinate, we evaluate the function at the vertex:
f(0) = 3(0)² = 0
So the vertex of the parabola is (0,0).
Since the coefficient of x² is positive, the parabola opens upwards, and the minimum value of the function occurs at the vertex. Therefore, the range of f(x) is all real numbers greater than or equal to zero.
For the rational function g(x) = 1/3x, the function is undefined when the denominator is equal to zero. Thus, we solve for the value(s) of x that make the denominator zero:
3x = 0
Dividing both sides by 3, we get:
x = 0
Therefore, the domain of g(x) is all real numbers except zero. The range of g(x) is all real numbers except zero, since the function cannot equal zero.
For the linear function h(x) = 3x, there are no values of x that make the function undefined. Thus, the domain of h(x) is all real numbers. The range of h(x) is also all real numbers, since the function is a straight line that passes through the origin and extend infinitely in both directions.

Michelle is out shopping and finds a bike originally valued at
$166.00. It is now on sale for 90% of the original price.
Answer:
$149.40
Step-by-step explanation:
The original value of the bike is worth 100%, and this is $166.00.
Let's work out 10%
To this, we divide the original amount by 10 (100% ÷ 10= 10%),
\(166.00 / 10 = 16.60\)
So now, we know that 10% = 16.60.
So, to get this to 90%, we multiply this value by 9 (10% × 9 = 90%),
\(16.60 * 9 =149.4\)
This means that the sale price at 90% is equal to $149.40.
