Step-by-step explanation:
Reflect over the Y axis, then translate (x+[-2], y+[-3])
The composition of transformations that map ABCD to EHGF will be [(x + 6), (y + 1)].
What is geometric transformation?Change is referred to as transformation. As a result, a geometric transformation entails making modifications to any geometric shape.
Vertices of the quadrilateral ABCD having coordinate A,B,C,D are (-5, 2),(-3, 4), (-2, 4),(-1, 2) respectively.
The image quadrilateral A'B'C'D' is formed by reflecting the supplied quadrilateral ABCD across the x-axis.
The rule for a point's reflection across the x-axis is:
(x, y) → (x , -y)
The picture point A' coordinates will be,
A(-5, 2) → A'(-5, -2)
Point E is produced by translating point A', as shown in the diagram. The rule for translating a point by h units right and k units up is as follows:
A'(x+h, y+k) → E(x', y')
By comparing coordinates of A' and E,
-5 + h = 1
h = 6
-2 + k = -1
k = 1
That is to say, the translation rule will be:
[(x + 6), (y + 1)]
Hence, the composition of transformations that map ABCD to EHGF will be [(x + 6), (y + 1)].

We are given a table that displays the current value of information technology giant, Cisco Inc. Using the table below, determine the closing price of Cisco Systems stock the previous day. A 9-column table with 1 row. Column 1 is labeled 52-week high with entry 15.34. Column 2 is labeled 52-week low with entry 14.88. Column 3 is labeled stock with entry C S C O. Column 4 is labeled Dividend with entry 0.15. Column 5 is labeled yield percentage with entry 0.997. Column 6 is labeled P E with entry 11.97. Column 7 is labeled Volume 100 s with entry 563,063. Column 8 is labeled close with entry 15.04. Column 9 is labeled net change with entry negative 0.02. a. $14.86 c. $15.06 b. $14.90 d. $15.04
Answer:
$15.06 answer C
Step-by-step explanation:
The previous day's closing price of Cisco Systems stock was $15.06. The correct option is c.
The closing price of Cisco Systems stock the previous day was $15.06.
We can see from the table that the "close" price listed in column 8 is $15.04 and the "net change" listed in column 9 is negative 0.02. This means that the stock price decreased by $0.02 from the previous day's closing price.
To find the previous day's closing price, we need to add the net change of -$0.02 to the current day's closing price of $15.04:
$15.04 + (-$0.02) = $15.02
Thus, the correct option is c.

A factory uses a special kind of lubricant to maintain its two milling machines. Weekly lubricant usage for each machine is an independent random variable (zero correlation). The first machine has a mean usage of 50.6 gallons and standard deviation of 12 gallons. The second machine has a mean usage of 64.4 gallons and standard deviation of 16 gallons.
Suppose that at the beginning of the week, the factory has a total of 135 gallons of lubricant in stock. The factory will not receive any replenishment of lubricant from its supplier until the end of the week. Assume that the total lubricant usage (of the two machines combined) follows a normal distribution. What is the probability that the factory will run out of lubricant before the next replenishment arrives?
Answer:
0.1587 = 15.87% probability that the factory will run out of lubricant before the next replenishment arrives
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Addition of normal variables.
When we add two normal variables, the mean is the sum of the separate means, and the standard deviation is the square root of the sum of the variances. So
The first machine has a mean usage of 50.6 gallons and standard deviation of 12 gallons. The second machine has a mean usage of 64.4 gallons and standard deviation of 16 gallons.
Total consumption is of both machines, combined. So
[tex]\mu = 50.6 + 64.4 = 115[/tex]
[tex]\sigma = \sqrt{12^2 + 16^2} = 20[/tex]
What is the probability that the factory will run out of lubricant before the next replenishment arrives?
Probability of consuming more than 135 gallons, which is 1 subtracted by the pvalue of Z when X = 135. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{135 - 115}{20}[/tex]
[tex]Z = 1[/tex]
[tex]Z = 1[/tex] has a pvalue of 0.8413
1 - 0.8413 = 0.1587
0.1587 = 15.87% probability that the factory will run out of lubricant before the next replenishment arrives

An airplane cuts through the morning sky. For every 1,000 feet that it climbs, the outside temperature drops 20 degrees Fahrenheit. What is the rate of temperature change in degrees Fahrenheit per foot? Complete the steps below to answer the question.
part A: Write the change in elevation and the change in temperature as rational numbers.
part B: Write a numerical expression to represent the rate of temperature change in degrees Fahrenheit per foot.
part C: What is the rate of temperature change in degrees Fahrenheit per foot?
part D: Now, consider the reverse situation: as the airplane descends, or drops, 1,000 feet in the air, the temperature rises 20 degrees Fahrenheit. Write a numerical expression representing the rate of temperature change in degrees Fahrenheit per foot.
part E: What is the rate of temperature change in degrees Fahrenheit per foot?
part F: How is the rate you found in part E related to the rate you found in part C? What does this mean?
Please answer each question separately! :(
Step-by-step explanation:
The air plane is rising so the change in elevation is +1000 feet. The temp dropped and is -20 degrees fahrenheit.
1 degree per 50 ft
For every 1,000 feet that it climbs, the outside temperature drops 20 ... What is the rate of temperature change in degrees Fahrenheit per foot.
Hope I helped
Answer:
Step-by-step explanation:
part A=The airplane is rising, so the change in elevation is +1,000 feet. The temperature is dropping, so the change in temperature is -20 degrees Fahrenheit.
Part B= -20 degrees fehrenheit/1,000 feet
Part C= -20 degrees fehrenheit/1,000 feet= -1 degrees fehrenheit/50 feet
The answer can also be written as -1 degrees fehrenheit/50 per foot.
Part D = The airplane is descending, so the change in elevation is -1,000 feet. The temperature is rising, so the change in temperature is +20 degrees Fahrenheit.
The rate of temperature change in degrees Fahrenheit per foot is 20/-1000
Part E= The answer can also be written as-1/-50
Part F= The rate in part E is equal to the rate in part C. It means that -1/50=1/-50=-1/-50

A study was conducted on students from a particular high school over the last 8 years. The following information was found regarding standardized tests used for college admitance. Scores on the SAT test are normally distributed with a mean of 1117 and a standard deviation of 194. Scores on the ACT test are normally distributed with a mean of 21.9 and a standard deviation of 3.8. It is assumed that the two tests measure the same aptitude, but use different scales.
If a student gets an SAT score that is the 77-percentile, find the actual SAT score.
SAT score =
Round answer to a whole number.
What would be the equivalent ACT score for this student?
ACT score =
Round answer to 1 decimal place.
If a student gets an SAT score of 1544, find the equivalent ACT score.
ACT score =
Round answer to 1 decimal place.
Answer:
The actual SAT score is 1260.6.
The equivalent ACT score for this student(77th percentile) is 24.7.
The equivalent ACT score to a SAT score of 1544 is 30.26.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
SAT:
[tex]\mu = 1117, \sigma = 194[/tex]
ACT:
[tex]\mu = 21.9, \sigma = 3.8[/tex]
If a student gets an SAT score that is the 77-percentile, find the actual SAT score.
This is X when Z has a pvalue of 0.77. So X when Z = 0.74.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.74 = \frac{X - 1117}{194}[/tex]
[tex]X - 1117 = 0.74*194[/tex]
[tex]X = 1260.6[/tex]
The actual SAT score is 1260.6.
What would be the equivalent ACT score for this student?
X when Z = 0.74, using [tex]\mu = 21.9, \sigma = 3.8[/tex]
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.74 = \frac{X - 21.9}{3.8}[/tex]
[tex]X - 21.9 = 0.74*3.8[/tex]
[tex]X = 24.7[/tex]
The equivalent ACT score for this student(77th percentile) is 24.7.
If a student gets an SAT score of 1544, find the equivalent ACT score.
First we find the z-score of the SAT, then we find the equivalent ACT score.
Z-score of SAT:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1544 - 1117}{194}[/tex]
[tex]Z = 2.2[/tex]
Equivalent ACT:
X when Z = 2.2. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.2 = \frac{X - 21.9}{3.8}[/tex]
[tex]X - 21.9 = 2.2*3.8[/tex]
[tex]X = 30.26[/tex]
The equivalent ACT score to a SAT score of 1544 is 30.26.
