Answer:
D. A=34, B=28
Step-by-step explanation:
In the bulletin points, it says that seconds 3-5 are decreasing. That means that those heights can't be higher than second 2 (34). The only option that works is option D.
----------------------
Option A is incorrect because it starts with 35ft which is higher than second 2(34) so that is automatically wrong.
Option B is incorrect because it is increasing instead of decreasing.
Option C is incorrect for the same reason as Option A: it starts with 35ft.
---------------------
Therefore, the only correct option is Option D.
Have a nice day!!

What is -1/2 (-5/6 plus 1/3) simplified
Answers
Answer:
0.25 or 5/12 - 1/6
Step-by-step explanation:
-1/2(-5/6+1/3), do PMDAS. (-5/6) = -0.833 (repeated) and (1/3) = 0.333 (repeated) and you add them both (-0.833 + 0.333) = -0.5 and -1/2 = -0.5 and when you multiply them both it would equal 0.25. or another explanation for the answer is 5/12 = 0.41666666666 and 1/6 = 0.16666666666 and when you subtract them both you get 0.25, I hope this was helpful.
Alan worked for 2 58 hours doing yard work. He spent 1 12 hours raking leaves. He spent the rest of the time cleaning out the flower bed. How long did he spend cleaning out the flower bed?
Answers
If it takes Luke 3 hours to rake a yard, and Don 5 hours to rake the same yard, how long will it take them to rake the yard together.
First we do it in our head. Take everything to 15 hours, the LCM of 3 hours and
and 5 hours. Since Luke can rake 1 yard in 3 hours, he can therefore rake 5
yards in 15 hours. Similarly since Don can rake 1 yard in 5 hours, he can
therefore rake 3 yards in 15 hours. So that's 5 yards plus 3 yards they can
rake in working simultaneously for 15 hours, therefore they rake 8 yards in 15
hours or 1 yard in 15%2F8ths of an hour. That's 1%267%2F8ths hours.
By algebra. Make this chart:
Yards raked Hours Rate in yards/hr
Luke 1 3 1/3
Don 1 5 1/5
Together 1 x 1/x
Luke's rate + Don's rate = their rate together
1/3 + 1/5 = 1/x
Solve that by clearing of fractions and you'll get the same answer as
when we do it in our head.

5. To determine the number of kids under the age of 5 in your neighborhood, you sit outside of
your apartment and count the number of kids under 5 that pass by between the hours of 7AM
and 8AM. Do you think this method will provide you with a representative random sample?
Explain your reasoning.
Answers
Answer:
It will not provide a representative random sample.
Step-by-step explanation:
This is because kids under five will only leave the house if they are going to the park or doing something with there parents. They don't go to school either so they most likely won't leave during the hours of 7 AM and 8 AM.

Mrs. Long keeps a garden in her backyard. The garden is in the shape of a rectangle. The garden is 27 feet wide. If the perimeter of the garden is 200 feet, what is the length of Mrs. Long’s garden
Answers
Answer:
so Area = length x width
Area = 450, width = 9
450 = 9 x length
divide 450 by 9, and you have the length.
Perimeter = length + length+ 9 + 9
and you got your perimeter!

How do you solve this proof?
Answers
Answer:
Angle = A
A7 = A4 (Alternate interior angles)
A14 = A11 (Vertically opposite angles)
A11 = A6(Corresponding angles)
A4 = A14 (Given)
From this, we can get A6 = A4
A6 and A4 are alternate angles and are equal. So c and d are parallel.
A7 + A10 = 180 (Linear pair of angles) - ( 1 )
A13 = A10(Alternate interior angles)
Putting A13 in place of A10 in ( 1 ),
A7 + A13 = 180
Hence proved

Which of the following is the 90% confidence interval for the true mean amount of time teenagers from this town watch sports?

C. (5.097, 7.404)
Step-by-step explanation:

The 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The formula for the confidence interval is:
CI = x ± tα/2 × (s/√n)
where x is the sample mean,
s is the sample standard deviation,
n is the sample size, and
tα/2 is the t-value with (n-1) degrees of freedom and a confidence level of 90%.
From data (x) is 6.25 hours and
s= 4.33 hours.
We also know the sample size (n) is 40.
To find the t-value with (n-1) degrees of freedom and a confidence level of 90%, we can use a t-table.
For 39 degrees of freedom and a confidence level of 90%
Let us find that the t-value is 1.684.
Substituting the values we have into the formula, we get:
CI = 6.25 ± 1.684 × (4.33/√40)
CI = (5.097, 7.404)
Therefore, the 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).

Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: A 10-percent salt solution freezes at 20 °F (-6 °C), and a 20-percent solution freezes at 2 °F (-16 °C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it.

What is parallelogram?The Greek word "parallelogram on," which means "bounded by parallel lines," is where the term "parallelogram" comes from. As a result, a parallelogram is a quadrilateral with parallel lines defining its boundaries. The opposite sides are parallel and equal in this shape. There are three main classes of parallelograms: square, rectangle, and rhombus each have their own distinct characteristics.
Given a parallelogram NPQR
and NS = 20 to find the value of SQ
since S is the intersecting point of diagonals of parallelogram,
so NS = SQ
The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal. The sum of the squares of a parallelogram's diagonals and all of its sides is the same.
SQ = 20
Hence for parallelogram SQ = 20.
