Answer:
85.95
Step-by-step explanation:
If the local tax was 8% and we want to know what is was without the tax then we need to do 93.42 times .92
[tex]93.42*.92=85.9464[/tex]
Since money only goes to the hundredths place we need to round there
[tex]85.95[/tex]
Based on the amount that Adrian spent in total, the cost without taxes was $86.50.
The cost of the clothes was $93.42 including tax.
Assuming the original cost is x, the equation is:
Total cost = Original cost x ( 1 + tax)
Solving would give:
93.42 = x × (1 + 8%)
93.42 = 1.08x
x = 93.42 / 1.08
= $86.50
In conclusion, the cost without taxes was $86.50.

We have to given that;
The area of a square is 36 square centimeters.
Now, We know that;
⇒ Area of square = Side²
Let the side of square = x
Hence, We can formulate;
⇒ x² = 36
⇒ x = √ 36
⇒ x = 6 centimeters

As a restaurant manager, you are tracking the number of ketchup bottles used each week in the restaurant. For six
weeks, the number of bottles used each week were 10, 14, 11, 10, 18, and 17.
What is the mean number of ketchup bottles used in one week?
A. 8
B. 10 C. 35/3
D. 40/3
E. 14
Answer:
The mean is 40/3 ⇒ D
Step-by-step explanation:
The mean of a set of data = The sum of data ÷ the number of data
∵ A restaurant manager tracking the number of ketchup bottles in
six weeks
∴ The number of data = 6
∵ The numbers of ketchup bottles used each week are 10, 14, 11, 10, 18, 17
→ Find their sum
∴ Their sum = 10 + 14 + 11 + 10 + 18 + 17
∴ Their sum = 80
∵ The mean = The sum of data ÷ the number of data
∴ The mean = 80 ÷ 6
→ Simplify it by dividing both by 2
∴ The mean = 40/3

Answer:
x = -2 and x = 1/3
Step-by-step explanation:
The simple way to solve this is to enter the equation into a graphing calculator and have it show you what the zeros are.
The solutions are x = -2 and x = 1/3.
__
One way to solve this is to factor it. The product of the leading coefficient and the constant is (3)(-2) = -6. You want to find factors of this number that have a sum equal to the coefficient of the linear term: 5.
-6 = (-1)(6) = (-2)(3) = ...
The first pair of factors listed here has a sum of 5, so we can rewrite the equation as ...
3x^2 -x +6x -2 = 0
Factoring pairs of terms, we have ...
x(3x -1) +2(3x -1) = 0
(x +2)(3x -1) = 0
The solutions are the values of x that make these factors zero:
x + 2 = 0 ⇒ x = -2
3x -1 = 0 ⇒ x = 1/3
The solutions are x = -2 and x = 1/3.

The Empirical Rule states that for bell-shaped distributions, about 68% of the values fall within 1 standard deviation of the mean. The heights of women at a large university are approximately bell-shaped, with a mean of 66 inches and standard deviation of 3 inches. Use this information to answer the questions. (a) What is the probability that a randomly selected woman from this university is 69 inches or taller
Answer: 0.16
Step-by-step explanation:
Let X be a random variable that represents the heights of women at a large university are approximately bell-shaped, with a mean of 66 inches and standard deviation of 3 inches.
According to the Empirical Rule, for bell-shaped distributions, about 68% of the values fall within 1 standard deviation of the mean.
About 68% woman have height between ( 66-3) inches and (66+3) inches.
i.e. About 68% woman have height between 63 inches and 69 inches.
The percentage of woman have height either less than 69 inches or greater than 69 inches =100% - 68%= 32% [both share equal area on curve.]
The percentage of woman have height is 69 inches or taller = 32%÷2
= 16%
Hence, the probability that a randomly selected woman from this university is 69 inches or taller =16%=0.16

[4G-07] Three individuals are completing a given task. The completion time for each individual is exponential random variable with mean 7, and is independent of one another. Find the probability that the first person to complete the task will do so in less than 5 minutes. (Use 4 decimals)
Answer:
P(X≤5) = 0.5105 (Approx)
Step-by-step explanation:
Assume, x = completion time of given task
Mean u = 7
So,
λ = 1/u = 1/7
So,
x ↔ exp(λ)
f(x) = P(X≤x) = [tex]1-e^{-\frac{1}{u}x }[/tex]
P(X≤5) = [tex]1-e^{-\frac{1}{7}5 }[/tex]
P(X≤5) = 0.5105 (Approx)

Third choice 7(x + 2) - 3x = 2/3(6x + 3)
Step-by-step explanation:
Choice answer 1 has infinitely many solutions since -1/2(8x + 6) - 2x = -3(2x + 1) → -6x - 3 = -6x - 3 = 0 → 0 = 0 [is always equal to].
Choice answer 2 has one solution since
-1/2(8x + 6) - 2x = -3(2x + 1) → -2x - 8 = 2x - 8 → x = 0 [is equal to in 1 condition].
Choice answer 3 has no solution since
7(x + 2) - 3x = 2/3(6x + 3) → 4x + 14 = 4x + 2 → 0 = -12 [is never equal to].
Choice answer 4 has infinitely many solutions since -2x + 5 - 3x + 12 = -5(x - 3) + 2 → -5x + 17 = -5x + 17 → 0 = 0 [is always equal to].

f(x)=x4+5x2+6
Answer:
4Step-by-step explanation:
Given function
f(x)=x⁴+5x²+6Zeros of the function:
x⁴+5x²+6 = 0(x²)² + 2x² + 3x² + 6= 0(x² + 2)(x² + 3) = 01. x²+ 2 = 0
x²= -2x₁,₂ = ±√2i2. x² + 3 = 0
x² = -3x₃,₄ = ±√3iAs we see there are 4 complex zeros

A decision maker is interested in estimating the mean of a population based on a random sample. She wants the confidence level to be % and the margin of error to be . She does not know what the population standard deviation is, so she has selected the pilot sample below. Based on this pilot sample, how many more items must be sampled so that the decision maker can make the desired confidence interval estimate? The decision maker should sample nothing more items to make the desired confidence interval estimate.
Complete Question
The complete question is shown on the first uploaded image
Answer:
The value is [tex]n = 146093[/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is [tex]E = 0.04[/tex]
The data is
8.70 4.79 10.95 15.19 14.06
16.99 1.22 9.02 14.39 5.73
7.28 3.22 2.66 6.13 6.93
Generally the sample mean is mathematically represented as
[tex]\= x = \frac{\sum x_i}{n}[/tex]
=> [tex]\= x = \frac{ 8.70 + 4.79 +\cdots + 6.93}{15}[/tex]
=> [tex]\= x = 8.48[/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{ \frac{ \sum (x_i - \= x)}{n} }[/tex]
=> [tex]\sigma = \sqrt{ \frac{ (8.70 - 8.48 )^2 + ( 8.70 - 8.48)^2 + \cdots + (6.93 - 8.48)^2 }{15} }[/tex]
=> [tex]\sigma = 5.14[/tex]
From the question we are told the confidence level is 98% , hence the level of significance is
[tex]\alpha = (100 - 98 ) \%[/tex]
=> [tex]\alpha = 0.02[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n -1[/tex]
=> [tex]df = 15 -1[/tex]
=> [tex]df = 14[/tex]
Generally from the t distribution table the critical value of at a degree of freedom of is
[tex]t_{\frac{\alpha }{2} , 14 } = 2.9768 [/tex]
Generally the sample size is mathematically represented as
[tex]n =[ \frac{t_{\frac{\alpha }{2} , 14 } * \sigma }{E} ]^2[/tex]
=> [tex]n =[ \frac{ 2.9768 * 5.136 }{0.04} ]^2[/tex]
=> [tex]n = 146093[/tex]
