The average commute to work (one way is 25 minutes according to the 2005 American Community Survey. If we assume that commuting times are normally distributed and that the standard deviation is 6.1 minutes, calculate the probability that a randomly selected commuter spends for the following cases. Round the final answers to four decimal places and intermediate z-value calculations to two decimal places. More than 31 minutes commuting one way P(X > 31) = Less than 8 minutes commuting one way P(X < 8)
The probabilities for this problem are given as follows:
P(X > 31) = 0.1635 = 16.35%.P(X < 8) = 0.0026 = 0.26%.How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation of the commute times are given as follows:
[tex]\mu = 25, \sigma = 6.1[/tex]
The probability that the time is more than 31 minutes is one subtracted by the p-value of Z when X = 31, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (31 - 25)/6.1
Z = 0.98
Z = 0.98 has a p-value of 0.8365.
1 - 0.8365 = 0.1635 = 16.35%.
The probability that the time is less than 8 minutes is the p-value of Z when X = 8, hence:
Z = (8 - 25)/6.1
Z = -2.79
Z = -2.79 has a p-value of 0.0026.

line is perpendicular to y=9 and goes thru (1,-1)
Answer:
x = 1
Step-by-step explanation:
y = 9 is a horizontal line. It intersects the y axis at (0,9) and for all value s of x, y = 9.
Therefore a line perpendicular to this line will be of the form x = k where k is some constant. It means that for all values of y, the x value is constant. The y value is irrelevant
Since the line passes through (1,-1), ie through x = 1, y = -1, the equation of the line is x = 1

Activity 1: When it says direction it refers to the tiles going horizontal and vertical for example the 4 and 9 going vetical to make vertical you must first add 4 + 9 which equals 13 then add a 2 under the 9 so it equals 15. And for 8 and 4 horizontal you must add 8 + 4 which equals 12 so add a three in between the 8 and 4 and for the 7 there is a two on the right of it so add 7 + 2 to equal 9 then add 6 to equal 15 then add a 1 in between the 8 and the 6 to equal 15 and add the 5 in the middle.
Activity 2: On the addition table on the left side of the table the number is the number you add to the number on top for example: the 2 at the top of the table plus the 6 on the same vertical line going down so it would be 2 + 6 which equals 8 as it tells you the answer and for 7 on the left side of the table and 3 at the top of the table with the vertical line would be 7 + 3 which equals 10.

Which of the following statements are always true? A) If f(t) is increasing, then the left-hand sum gives an overestimate of the integral from a to b of f(t)dt. B) If f(t) is concave up, then the left-hand sum gives an overestimate of the integral from a to b of f(t)dt.
The statement that is true about integrals is; A) If f(t) is increasing, then the left-hand sum gives an overestimate of the integral from a to b of f(t)dt.
How to interpret Riemann sums?Left-Hand Sums and Right-Hand Riemann sums usually give us different approximations of the specific area under a curve.
Now, If one sum gives us an overestimated value and then the other gives us an underestimated value, then we can try to find out what exactly the actual area under the curve might possibly be. It should be noted that left-hand sum will be an under-estimate of the specific area of R. Thus, as f is increasing, a left-hand sum will definitely use the smallest value of f on each sub-interval. This therefore tells us that any left-hand sum will not cover all of R and also any right-hand sum will be an over-estimated value of the area of R.
Thus, Since f is increasing, a right-hand sum will utilize the largest value of f on each specific sub-interval. Thus, right-hand sum will definitely cover R and others.
From the above, option A is true because if the graph is increasing then the left-hand sum gives an overestimated value of the actual value.
Meanwhile, option B is false because if the graph is concave upwards, then the trapezoid approximation is an overestimated value, and as such the midpoint will be underestimated.

If a random sample of fifteen 18-year-old men is selected, what is the probability that the mean height x is between 68 and 70 inches? (Round your answer to four decimal places.)
The probability that the mean height x is between 68 and 70 inches is found as 37.28%.
What is meant by the term z score?The z-score effectively represents the standardized distance in units of "number standard deviations" between the raw score (procured from a population assuming a normal distribution) as well as the population mean.The z-score is written as follows:
z = (x - μ)/σ
In which,
x = between 68 and 70 inches.
μ = mean 69 inches
σ = standard deviation 6 inches
Put the values in the formula,
Probability that the mean height x is between 68 and 70 inches
P(68 < x < 70) = (68 - 69 / 6) < z < (70 - 69 / 6)
P(68 < x < 70) = (-0.16) < z < (0.16)
P(68 < x < 70) = 0.4364 - 0.0636
P(68 < x < 70) = 0.3728
P(68 < x < 70) = 37.28%

Find the solution of this system of equations 6x+2y=4 -5x+8y=45
Answer:
We can solve this problem using the elimination method, and in the elimination method we need to change equations so that one of the variables (either x or y) is eliminated. to do this, we can multiply one or both of the equations by constants so that the coefficients of one of the variables becomes equal so we can eliminate it from the equation. This will allow us to add the equations together and eliminate that variable.
For example, we could multiply the first equation by -5 and the second equation by 6, to get:
-30x + 10y = -20
-30x + 48y = 270
Then, we can add these equations together to eliminate the x variable:
-30x + 10y = -20
-30x + 48y = 270
-60x + 58y = 250
We can then solve for y by dividing both sides of the equation by 58:
y = 250 / 58
y = approximately 4.31
Once we have the value of y, we can substitute it back into one of the original equations to solve for x. for example, if we substitute it into the first equation, we get:
6x + 2 * 4.31 = 4
6x = 4 - 8.62
6x = -4.62
x = -0.77
Therefore, the solution to the system of equations is x = -0.77 and y = 4.31.

Total balance in Annette's charge account is $1727.12 with 6% of tax on all order.
What is Percentage ?The Latin phrase "per centum," which meaning "by the hundred," was the source of the English word "percentage." Fractions having a denominator of 100 are called percentages. In other words, it is a relationship where the value of the entire is always assumed to be 100.
Finding the percentage of a whole in terms of 100 is what percentage calculation refers to. A percentage can be found in one of two ways:
use the unitary approach.by adjusting the fraction's denominator to 100.It should be noted that when the denominator is not a factor of 100, the second technique of percentage calculation is not applied. In these situations, we employ the unitary technique.
1 dozen of Rose costs = $30.96
1 dozen of chrysanthemums costs = $17.80
1 dozen of of tulips costs = $ 21.10
Total Spending = 16 dozens of roses + 40 dozen of chrysanthemums + 20 dozens of tulips
= 16 * 30.96 + 40 * 17.80 + 20 *21.10
= $1629.36
There is a 6% sales tax on all order = 6% of 1629.36 = $ 97.76
Total balance in Annette's charge account is $ 97.76 + 1629.36 = $1727.12.

What is the inverse of the function shown?
The inverse of the function shown is (x + 5).
What is the inverse of the function?
A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "[tex]f^{-1}[/tex]" or "[tex]F^{-1}[/tex]." Here, (-1) should not be confused with an exponent or a reciprocal.
Coordinates of the given line are (8,3) and (-2,-7)
The function of the given graph for two points form is
[tex]y-y_{1} = \frac{y_{2}-y_{1} }{x_{2} -x_{1}} (x-x_{1} )[/tex]
or, [tex]y-3 = \frac{-7-3 }{-2-8} (x-8 )[/tex]
or, y - 3 = x - 8
or, y = x -8 + 3 = x - 5
y = x - 5
To find the inverse, replace x with y and y with x then, we get
x = y - 5
y = x + 5
[tex]f^{-1}[/tex] = x + 5
Hence, the inverse of the function shown is (x + 5).
