Answer:
Tyler is correct. The temperature dropped at a rate of about 4° per hour between 4 and 6, while the temperature dropped at about 2.25° per hour between 6 and 10.
Edit: Explanation
The question is asking about which window of time had a faster decline in temperature, not a larger total change in temperature.
In a 2 hour timeframe, the temperature dropped 8°. (4-6 PM)
In a separate 4 hour timeframe, the temperature dropped 9°. (6-10 PM)
To find which window had a faster change in temp, I took the total temperature drop for each timeframe, then divided it by the number of hours each drop took.
8° / 2 = 4° per hour for 4-6 PM
9° / 4 = 2.25° per hour from 6-10 PM
Since the speed at which the temperature dropped per hour was greater from 4-6 PM than 6-10 PM, Tyler was correct.
Answer:
i agree with Mai because she/he (im not really sure) said that the temperature changed quicker in the time between 6 and 10 pm. the temperature change was 9 in those 4 hours.
Step-by-step explanation:
well there's a 4 hour difference between all 3 of the times
4 pm - 6pm
25 - 17 = 8
8 degree difference
6 pm - 10 pm
17 - 8 = 9
9 degree difference
the temperature changed quicker during 6 pm to 10 pm
Zach wants to make a profit of more than 300 for painting 4 identical too rooms. The profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is 32.50 for each room. Which inequality and solution represent the dollar amount n, that zack must be paid for each room, if he is to make a profit more than 300
Given :
Zach wants to make a profit of more than 300 for painting 4 identical too rooms.
The cost of supplies is 32.50 for each room.
To Find :
Which inequality and solution represent the dollar amount n, that zack must be paid for each room, if he is to make a profit more than $300.
Solution :
Profit is given by :
Profit = S.P - C.P
Now, it is given that profit > 300 .
Profit = S.P - C.P > 300
[tex]4n - 4\times 32.5 > 300\\\\n - 32.5 > 75\\\\n > \$107.5[/tex]
Hence, this is the required solution.

3) The height of an object that is thrown straight up from a height of 6 feet
above ground is given by h(t) = -15t2 + 25t + 6, where t is the time in
seconds after the object is thrown. Find the average rate of the object from
1 to 4 seconds.
Answer:
- 44 feets
Step-by-step explanation:
Given the model:
h(t) = -15t2 + 25t + 6
Average height of object from 1 - 4 seconds
At :
t = 1
h(1) = -15(1)^2 + 25(1) + 6 = 16 feets
t = 2
h(2) = -15(2)^2 + 25(2) + 6 = - 4 feets
t = 3
h(3) = -15(3)^2 + 25(3) + 6 = - 54 feets
t = 4
h(4) = -15(4)^2 + 25(4) + 6 = -134 feets
Average height:
(16 + (-4) + (-54) + (-134)) / 4 feets = (- 176 / 4) feets
= - 44 feets

Research in March 2019 suggests that 40% of U.S. Adults approve of way President Trump is running the country. We randomly sample 50 U.S. Adults and find that 35% approve of way President Trump is running the country. What is the probability that a random sample of 50 U.S. Adults has less than 35% with this opinion? (Round standard error to 2 decimal places before calculating Z. Round Z to 2 decimal places before using the Normal Distribution Calculator.) Group of answer choices about 0.24 about 0.76 about 0.48
Answer:
The probability is [tex]P( \^ p < 0.35)= 0.2388 [/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.40
The sample size is n = 50
Generally the standard error is mathematically represented as
[tex]\sigma_{\= p} = \sqrt{\frac{p * (1- p)}{n} }[/tex]
=> [tex]\sigma_{\= p} = \sqrt{\frac{0.40 * (1- 0.40)}{50} }[/tex]
=> [tex]\sigma_{\= p} = 0.07[/tex]
Generally the probability that a random sample of 50 U.S. Adults has less than 35% with this opinion is mathematically represented as
[tex]P( \^ p < 0.35) = P(\frac{\^ p - p}{\sigma_{\= p}} < \frac{0.35 - 0.40}{0.07} )[/tex]
Generally [tex]\frac{\^ p - p}{\sigma_{\= p}} = Z (The \ standardized \ value\ of \ \^ p )[/tex]
=> [tex]P( \^ p < 0.35)=P(Z < -0.71)[/tex]
From the z table
[tex]P(Z < -0.71) = 0.2388[/tex]
So
[tex]P( \^ p < 0.35)= 0.2388 [/tex]

It normally takes Julius 2 hours to mow the yard, but because he is in a hurry he asks his son, Marcos, to help him. If just his son was doing the yard work it would take him 3 hours. How long will it take if both are working together? Use the formula 1/T_1 +1/T_2 =1/T_both where T_1 is the time required for Julius to complete the job alone, T_2 is the time required for Marcos to complete the job alone, and T_both is the time required to complete the job when they both work together. Answer as a decimal, rounded to one decimal place.
Answer: 1.2 hours
Step-by-step explanation:
Given: : Time taken by Julius to complete the job alone: [tex]T_1=2\text{ hours}[/tex]
Time taken by Marcos to complete the job alone : [tex]T_2=3\text{ hours}[/tex]
Let the time taken by both to complete the job together = T
[tex]\dfrac{1}{T}=\dfrac{1}{T_1}+\dfrac{1}{T_2}[/tex]
[tex]\Rightarrow\ \dfrac{1}{T}=\dfrac{1}{2}+\dfrac13\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{3+2}{2\times3}\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{5}{6}\\\\\Rightarrow\ T=\dfrac{6}{5}=1.2[/tex]
Hence, it will take 1.2 hours to complete the job by working together.

a rectangle is 25 feet long its area 375 square feet.
What is the perimeter of the rectangle
Area = length x width.
Divide the area by the length of find the width.
Width = 375/25 = 15 feet.
The perimeter is the sum
Of the 4 sides.
Perimeter = 25 + 25 + 15 + 15 = 80 feet.
The perimeter of a rectangle is 80 feet.
Given that, the length of a rectangle=25 feet and area of the rectangle=375 square feet.
We need to find the perimeter of a rectangle.
What is the formula to find the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
We know that, the area of a rectangle=length×width
Now, the area of a rectangle=25×width
⇒375=25×width
⇒Width=15 feet
So, perimeter = 2(25+15).
=80 feet
Therefore, the perimeter of a rectangle is 80 feet.
