Answer all 3 questions.
last week, several gas stations in a neighborhood all charged the same price for a gallon of gas.The table below shows how much gas prices have changed from last week to this week.
a. Order the numbers in the table from least to greatest.
b. Which gas station has the cheapest gas this week?
c. Critical Thinking. Which gas station changed their price the least this week?
Gas and Samson. Star
Go. Gas. Gas
-6.6. 5.8. -6 3/4
Corner store. tip top
27/5. shop
-5 5/8
Without the correctly formatted data, we cannot give direct answers. However, the answers would come from ordering the data from least to greatest, identifying the least positive or most negative change as the cheapest gas, and the smallest change as the least change in price.
Explanation:Unfortunately, the question you provided is a bit unclear because the table is not formatted correctly. However, it's clear that you're asked to analyze a set of data, which refers to changes in gas prices at several gas stations. Usually, to order the numbers from least to greatest, you would list them in ascending numerical order, taking into account whether they are positive or negative, with negative numbers being less than positive numbers. The gas station with the cheapest gas this week would be the one with the least positive change or the greatest negative change. The gas station that changed their price the least would be the gas station with the smallest change in price, whether positive or negative. However, without the correct formatting of data, I am unable to provide specific answers. It's always important to check your data for clarity in order to perform accurate mathematical analyses. These principles of data analysis and number order are crucial skills in your mathematical education.

Find an equation of the normal line to the parabola y = x2 â 9x + 7 that is parallel to the line x â 7y = 2.
The normal line to the parabola y = x^2 - 9x + 7 that is parallel to the line x - 7y = 2 is y = -7x + 65, which was determined by finding the normal slope and point of tangency using the derivative.
Explanation:In mathematics, the normal line to a curve at a particular point is the line that is perpendicular to the tangent of the curve at that point. First, it's important to establish that any line parallel to x - 7y = 2 would have the same slope, which in this case is 1/7. To find the normal line, we need a line that is perpendicular to this -- hence, it would have a slope of -7.
Now, to find the point of tangency, you must take the derivative of y = x^2 - 9x + 7, making it 2x - 9. Set this equal to -7 (the slope of the normal line) and solve for x, which comes out to be 8. Substituting x = 8 back into our parabola equation gives us y = -9. Therefore, our point of tangency is (8, -9).
Finally, using the point-slope form of a line formula, we can find our equation of the normal line, which is y - (-9) = -7*(x - 8), simplifying to y = -7x + 65.

the volume of 10000 drops of liquid is 100 fluid ounces. what is the volume of 10 drops?
Answer:
0.1 fluid ounces
Step-by-step explanation:
If 10000 drops lof liquid is 100 fluid ounces we can determine the drops of liquid per fluid ounces by dividing the two values:
[tex]100/10000=0.01[/tex]
Therefore 0.01 fluid ounces is equivalent to 1 drop. We have our conversion factor now we can determine the volume by multiplying the conversion factor by the number of drops:
[tex]0.01*10=0.1[/tex]
10 drops is 0.1 fluid ounces
f(x) = x2 + 5x – 1 is shifted 3 units left. The result is g(x). What is g(x)?
A. g(x) = (x – 3)2 + 5(x – 3) – 1
B. g(x) = x2 + 5x + 2
C. g(x) = (x + 3)2 + 5x – 1
D. g(x) = (x + 3)2 + 5(x + 3) – 1
Answer:
g(x) = (x+3)² + 5(x+3) – 1.
Step-by-step explanation:
Given : f(x) = x² + 5x – 1 is shifted 3 units left.
To find : The result is g(x). What is g(x).
Solution : We have given that
f(x) = x² + 5x – 1 is shifted 3 units left.
By the transformation rule : If f(x) →→ f(x +h) shifted by h unit left .
f(x) = x² + 5x – 1 is shifted 3 units left.
Here , h = 3
Then g(x) = (x+3)² + 5(x+3) – 1.
Therefore, g(x) = (x+3)² + 5(x+3) – 1.

At the corner store, Nico bought 5 pencils for $0.10 each and 3 pens for $0.50 each. He used t to represent the sales tax, in dollars, that he also paid. He paid a total of $2.12, including tax.
Nico wrote this equation to represent what he paid. What errors, if any, did he make?
5(0.10) + 3(0.50) - t = 2.12
He should have multiplied 0.10 by 3 instead of 5.

Assume that you select two 3-digit numbers at random from the set of consecutive integers from 000 through 999. The selections are made with replacement and are independent of one another. If the two numbers are the same, you make $700. If they are different, you lose $2. A random variable XX is defined as your gain or loss.
How many different values are possible for the random variable XX
Answer:
the answer is: 2
Step-by-step explanation:
from 000 to 999 makes a total of 1000 numbers from which we are selecting two numbers with replacement. This means that the possible combinations will be double of 1000.
1000 * 1000 = 1000000
to have the same number twice means that the possible combinations will be only 1000. (As there are only 1000 numbers).
But whether they are same or not there will be only two possible values of XX , 2 dollars or 700 dollars which will be the loss or gain for one trial, as the numbers picked will either be same or different.

Find the probability of the following event, expressing it as a fraction in lowest terms. HINT [See Example 1.] She does not have all the green ones.
Explanation of calculating the probability of choosing 3 green marbles out of 10 from a bag with 50 marbles.
Explanation:
The probability of choosing exactly 3 green marbles if a total of 10 marbles are selected from a bag filled with 50 marbles, 15 of which are green, can be calculated as follows:
Calculate the total number of ways to choose 3 green marbles out of 15: C(15, 3).Calculate the total number of ways to choose 7 non-green marbles out of 35: C(35, 7).Find the total number of ways to choose 10 marbles out of 50: C(50, 10).Calculate the probability by dividing the product of the above two calculations by the total ways to choose 10 marbles.A music school has budgeted to purchase 3 musical instruments. they plan to purchase a piano costing $4,000, a guitar costing $600, and a drum set costing $750. the mean cost for a piano is $5,000 with a standard deviation of $2,000. the mean cost for a guitar is $550 with a standard deviation of $250. the mean cost for drums is $950 with a standard deviation of $100. (enter your answers to two decimal places.) how many standard deviations above or below the average piano cost is the piano
To solve this, we can use the z statistic. The formula for z score is given as:
z = (x – u) / s
where x is the actual cost = 4000, u is the mean cost = 5000, and s is the standard deviation = 2000
Solving for z:
z = (4000 – 5000) / 2000
z = - 0.5
Therefore the piano cost is only 0.5 standard deviations below the average cost.
Which of the following represents the zeros of the function
g(x) = x3 - 9x2 + 2x + 48 ?

D. x = -6, x = 4 , and x = -9

Owl can clean piglets house in 25 minutes. eeyore can clean piglets house in 40 minutes. how long will it take owl and eeyore to do the job if they work together?
Let us say that the task of cleaning the house is equal to 1 job. Therefore the rates are:
rate of Owl = 1 job / 25 minutes
rate of eeyore = 1 job / 40 minutes
So working together, the time is:
(1 / 25) + (1 / 40) = 1 / t
0.065 = 1 / t
t = 15.38 minutes
So it takes about 15.38 minutes working together.
