If Fernando paid $450 for a netbook that was 75% of the original price, what was the original price?
Answer:
$600
Step-by-step explanation:
450 = 3/4 (because 75%=3/4)
450/3=150. 150 = 1/4, or 25%. Now it's just as simple as multiplying 150 4 times to get 100%, or the original cost, 150 times 4 equals 600. Therefore the notebooks original price is $600

The length of a rectangular parking area is four times the width. The perimeter is 150 yd . Find the length and width of the parking area.
The width of the rectangle = 15 yd
The length of the rectangle = 60 yd.
What is the Perimeter of a Rectangle?Perimeter of a rectangle = 2(length + width).
Given the following:
Width of the rectangle = w
Length of the rectangle = 4w
Perimeter of the rectangle = 150 yd.
Therefore:
2(4w + w) = 150
2(5w) = 150
10w = 150
10w/10 = 150/10
w = 15
Width of the rectangle = w = 15 yd
Length of the rectangle = 4w = 4(15) = 60 yd.

For the following exercise, find the domain and range of the function below using interval notation.
Domain:
Range:
The domain and range of the function is -3 ≤ x < 7 and -7 ≤ x < 6 respectively.
What is domain and range?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
For domain :-
Since, the domain is the set of all allowed x inputs of a function.
The smallest x can get is x = -3 as shown by the left-most point.
The largest x can get is x = 7, though we can't actually reach this value due to the open hole at the right-most point.
The interval of all possible x values is -3 ≤ x < 7 which converts to the interval notation [-3, 7)
We use a square bracket to include the endpoint and a parenthesis to exclude the endpoint.
We can say "x is any number between -3 and 2, including -3 but excluding 2".
For range :-
Since, the range is the set of all allowed y inputs of a function.
The smallest x can get is x = -7 as shown by the left-most point.
The largest x can get is x = 6, though we can't actually reach this value due to the open hole at the right-most point.
The interval of all possible x values is -7 ≤ x < 6 which converts to the interval notation [-7, 6)

The value of integral ₀∫¹ ( eˣ - 2 )² dx is 8 + ( e² - 1) / 2 - 4e.
When infinitesimal data are combined, notions such as displacement, area, and volume can be created. An integral assigns numbers to functions in a way that describes these concepts. Integration is the action of locating integrals.
Consider the integral expression,
₀∫¹ ( eˣ - 2 )² dx
Using ( a + b )² = a² + b² + 2ab
[tex]\int_0^{1}( e^{x} - 2 )^{2} dx = \int_0^{1}(e^{2x}+4-2e^{x})dx[/tex]
[tex]\int_0^{1}( e^{x} - 2 )^{2} dx = \int^0_{1}e^{2x} dx +\int_0^{1}4 dx - \int_0^{1}4e^{x} dx[/tex]
Now, integration of eˣ is eˣ + c where c is constant.
Therefore,
[tex]\int_{0}^{1} ( e^{x} - 2 )^{2} dx = [ \frac{e^{2x}}{2} ]_0^{1} + [ 4x ]_0^{1} - [ 4e^{x}]_0^{1}[/tex]
₀∫¹ ( eˣ - 2 )² dx = ( e² / 2 - e⁰/2 ) + ( 4 - 0 ) - ( 4e¹ - 4e⁰ )
₀∫¹ ( eˣ - 2 )² dx = e² / 2 - 1/2 + 4 - 4e + 4
₀∫¹ ( eˣ - 2 )² dx = e² / 2 - 4e + 8 - 1/2

Hazel and Luna are in different sections of MTH 134. They both took Test 1 and their instructors indicated that in each section, the scores fell into a normal distribution. Hazel made a score of 93 points and Luna made a score of 68 points. In Hazel's section, the Test 1 scores had a mean of 80 and a standard deviation of 8. In Luna's section, the mean was 40 with a standard deviation of 15. Use the Empirical Rule to determine which student did "better" and why.
Using z-scores, it is found that due to the higher z-score, Luna did better on the exam.
What are z-scores?The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.From the two bullet points, it is found that the student who did "better" is the one whose grade has the higher z-score.
For Hazel, the parameters are given as follows:
[tex]X = 93, \mu = 80, \sigma = 8[/tex]
Hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (93 - 80)/8
Z = 1.625.
For Luna, the parameters are given as follows:
[tex]\mu = 68, X = 40, \sigma = 15[/tex]
Hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (68 - 40)/15
Z = 1.87.

What is compound interest?Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
We know that the compound interest is given as
[tex]\rm A = P \left ( 1 + \dfrac{r}{n} \right ) ^{nt}[/tex]

The length of a rectangle is three more than triple the width. If the perimeter is 166 inches, find the
dimensions.
The dimensions of the rectangle are; length 63 inches and width is 20 inches.
What is defined a the perimeter of rectangle?The perimeter (P) of such a rectangle would be the total distance of all its sides. A rectangle has two equal lengths as well as two equal widths because its opposite sides are equal.Let 'L' be the length of the rectangle.
Let 'W' be the breadth of the rectangle.
As, the length of a rectangle is three more than triple the width.
Thus,
L = 3 + 3W
The formula for the perimeter is;
Perimeter = 2 (L+W)
The value of perimeter is 166 inches.
Thus,
166 = 2(3 + 3W +W)
166 = 2(3 + 4W)
166 = 6 + 8W
166 - 6 = 8W
W = 20
W = width = 20 inches
L = 3 + 3W
L = 3 + 3(20)
L = 3 + 60
L = 63 inches.
Thus, the dimensions of the rectangle are; length 63 inches and width is 20 inches.

The sampling distribution of the estimator is not the same shape as the distribution of the population parameter. The sampling distribution of the estimator is not the same shape as the distribution of the population parameter. The expected value of the estimator is not equal to the population parameter. The expected value of the estimator is not equal to the population parameter. The variability of the sampling distribution of the estimator is not equal to the variability of the population parameter.
The condition that will create a biased estimator of a population parameter is D. The expected value of the estimator is not equal to the population parameter.
What is a population parameter?It should be noted that a parameter is a descriptive measure applied to a whole population. There are numerous population parameters exist. For instance, the population size (N) is one parameter.
For T(x) to be an unbiased estimator of population parameter, it is necessary that the expected value of the estimator is equal to population parameter.
