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

Fred earns $ 45 mowing the lawn. He spends $ 5 on music, and puts half of what's left in a savings account. He then gets another $ 10 for washing his neighbor's car. First, write the expression that represents the number of dollars Fred keeps (and does not put in his savings account), and then simplify.
Answer:
$30
Step-by-step explanation:
Given that :
Amount earned for mowing = $45
Amount spent on music = $5
Amount earned for washing neighbor's car = $10
Amount saved = half or remaining amount
Amount of dollars Fred keeps =
Amount Fred keeps:
[(Amount earned - amount spent) / 2] + $10
[($45 - $5) / 2] +
($40 / 2) + $10
= $20 + $10
= $30

Ally collects stickers as a hobby. She gives her sisters of her stickers.
She then gives her cousin of the remainder.
Ally says that she has 3/5 of the stickers in the end because 1-1/5-1/5=3/5
• Explain why Ally's reasoning is incorrect.
What should the correct answer be?
Explain how you arrived at your answer.
Answer:
[tex]\frac{16}{25}[/tex]
Step-by-step explanation:
Ally gives her sister = 1/5 stickers
Ally gives her cousin = 1/5 of the remainder stickers
Assume Number of sticker Ali has = 1
Remainder after giving stickers to her sister = 1 - 1/5 = 4/5
Number of stickers she gave her sister = [tex]\frac{1}{5}\times\frac{4}{5}[/tex]
=[tex]\frac{4}{25}[/tex]
Sticker she has = [tex]1-\frac{1}{5}-\frac{4}{25}[/tex]
=[tex]\frac{25-5-4}{25}[/tex]
=[tex]\frac{16}{25}[/tex]
Sticker left with Ally is equal to [tex]\frac{16}{25}[/tex].

A major reason that decision making is often not such a rational process is that there are: Suppose we have H0:µ1= µ2 versus HA: µ1 ≠ µ2, with level of significance of α =.05 and critical values of zα/2 = ± 1.96, and the computed Test Statistics value of Z = -1.07. What is our decision?
Answer:
b. 710
Fail to reject H0
Step-by-step explanation:
Forecast for July 14 :
Assume there are 4 wwwks in each month :
January to June = ( 4 * 6 months) = 24 weeks in 6 months ;
July - July 14 = 2 weeks :
2 + 24 = 26 weeks
The model given :
Y = 450 + 10t
Y = 450 + 10(26)
Y = 450 + 260
Y = 710
2.)
Test is a 2 tail test :
Zstatistic = - 1.07
At 95% confidence = ±1.96
Zcritical = - 1.96
Hence,
Reject H0 if ;
Zstatistic < Zcritical
-1.07 > 1.96
Hence, fail to reject H0.
