HELP PLEASE!!!!!! Answer all questions, please... Linear? Is there a pattern in the data points? If so, describe the pattern.

Do the points show a positive linear association, a positive nonlinear association, a negative linear association, a negative nonlinear association, or no association?

What does this association tell you about the relationship between the variables?

Are there any clusters or outliers?

Answers

This is linear as long as the points can be seen following the trend line. The graph shows a positive association. This tells you that the average height increases with rainfall. A cluster can be found in between 0.25 and 0.5 on the y-axis, there are no outliers. The pattern shows the trend line increasing at a steady, somewhat predictable rate.

One leg of a 45 - 45 - 90 triangle measures 12 centimeters what is the length of the hypotenuse

Answers

The angles of the triangle are given as to have measures of 45°-45°-90°. This entails that the triangle is an isosceles triangle where the 2 legs of the triangle are of equal length. We calculate as follows:

c² = a² + b²

c² = 2a²

4² = 2a²

a = 2√2

Hope this answers the question.

The median of a set of three numbers is x. there at least three numbers in the set. Write an algebraic expression, in terms of x, to represent the median of the new set of numbers obtained by
a] adding 1/8 to every number in the set
Let the numbers be w,x,y
adding 1/8 to the number we get:
(w+1/8),(x+1/8),(y+1/8)
the new median will be:
(x+1/8)

b. subtracting 9 1/4 from every number in the set
Given our data set is w,x,y
adding 9 1/4 to each number we get:
(w+9 1/4),(x+9 1/4), (y+9 1/4)
thus the new median is:
(x+9 1/4)

c]multiplying -5.8 to every number in the set and then adding 3 to the resulting numbers
Multiplying each number by -5.8 we get:
(-5.8w),(-5.8x),(-5.8y)
adding 3 to these numbers we get:
(-5.8w+3),(-5.8x+3),(-5.8y+3)
thus the new median is:
(-5.8x+3)

d]dividing every number in the set by 0.5 and then subtracting 1 from the resulting numbers
dividing each number in our set by 0.5 we get:
(w/0.5),(x/0.5),(y/0.5)
this will give us:
(2w),(2x),(2y)
then subtracting 1 from the above we get:
(2w-1),(2x-1),(2y-1)
thus the median will be:
(2x-1)

e. adding 7.2 to the greatest number in the set
from our set:
w.x.y
the greatest number is y, then adding 7.2 to the greatest numbers gives us:
y+7.2
thus new series is:
w,x,y+7.2
thus the median is:
x
Conclusion
The median doesn't change

f. subtracting 4.2 from the least number in the set
from our set w,x,y; subtracting 4.2 from the least number gives us:
w-4.2
the new set is:
w-4.2, x, y
thus the new median is x
Conclusion
The median doesn't change

The Fibonacci series starts (usually with two ones) and a two. for the first 3 numbers. It looks like this
1 1 2 3 5 8 etc.

Yours is a variation in the way it starts but it follows the same rule. 
To get the next term in the series, you add the previous 2 terms.

So for example, to get 8, you would add 3 and 5 together. To get 13 your add 5 and 8 together.

To get the next branch add 8 and 13 together. That makes 21. To get the one after that, add 21 and 13 together. 21 + 13 = 34

When you study recursion, this series is going to come up a great deal.

Lydia brought 4 liters of lemonade to a picnic. She poured 160 millimeters of lemonade for each of her 2 friends and 215 millimeters for another friend. How much lemonade does Lydia have left

Answers

1 litre=1000mL so we know that 4x1000= 4000mL

Since she poured 160 mL for TWO friends

160x2=320

She then says that another friend has 215 mL of lemonade.

So that means

4000-320-215= 3465 mL

Therefore Lydia has 3465mL or 3.465L of lemonade left

Suppose the volume of a right circular cylinder is 225 cubic meters and the area of its base is 25 square meters. What is the height of the cylinder?

Answers

Volume of a cylinder: [tex] \pi [/tex]r²h

First we need to find the radius of the cylinder. It's area is 25. We can plug that into the area formula, [tex] \pi [/tex]r² and solve for r (radius).

[tex] \pi [/tex]r² = 25
Divide both sides by [tex] \pi [/tex].

r² = 7.96
Square root both sides.

r = 2.82 meters

Now plug the radius + volume into the volume formula and solve for h.
[tex] \pi [/tex]2.82²h = 225
Divide by [tex] \pi [/tex].

2.82²h = 71.62
Divide by 2.82².

h = 9

The height of the cylinder is 9 square meters.

The height of the cylinder will be 9 meters.

What is the volume of a right circular cylinder?

Let r be the radius, h be the height, and A be the area of the cylinder. Then the volume of the cylinder will be given as,

V = π r²h cubic units

V = Ah cubic units

Suppose the volume of a right circular cylinder is 225 cubic meters and the area of its base is 25 square meters. Then the height of the cylinder is calculated as,

225 = 25h

h = 225 / 25

h = 9 meters

Find the equation for the line that passes through A's hypotenuse
plz show work

Answers

The answer is:  " 1 " 
_________________________________________
              " y = -2x + 1 " .
_________________________________________
Explanation:
_________________________________________

Look at the hypotenuse for "ΔA" and note the coordinates of where the hypotenuse crosses the "y-axis".

The coordinates are:  " (0, 1) " ;  that is:  " x = 0 ;  y = 1 " .

So, the problem /question is:  " y = -2x + [?] " ; 

→ Plug in " 1 " for "y" ;  as follows:

→  " 1 = -2x + [?] " ; 

→  We know that "x = 0";  

→ when "x = 0" ;    →  " -2x " = " (-2 * 0) = 0 ;  

So,  1 = 0 + [?] ; 

The answer is " 1 " ; since:  " { 0 + 1 = 1 .} .

Or, with a more detailed explanation:
_______________________________________________________
  →  1  =  0  +  [?]  ;

Subtract "0" from EACH SIDE of the equation;
 
  →  1  − 0 =  0  +  [?]  − 0 ; 

to get:

 →  1 = [?] ;

A kennel has 100 dogs in total, some are puppies and some are adult dogs. the ratio of puppies to adults in a kennel is 1:4 how many puppies are there

Answers

Puppies : Adults = 1 : 4

Total parts = 1 + 4 = 5
 
5 parts = 100 dogs
1 part = 100 ÷ 5 = 20 dogs

Answer: 20 puppies
Final answer:

The number of puppies in the kennel is 20, given that the ratio of puppies to adult dogs is 1:4 out of a total of 100 dogs.

Explanation:

In the given scenario, the number of dogs in the kennel is 100, and the ratio of puppies to adult dogs is 1:4. This means that for every one puppy, there are four adult dogs. Therefore, the total number of sections we have is 1 (for puppies) + 4 (for adult dogs), which equals 5. To find out how many puppies there are, we divide the total number of dogs by the total sections, and multiply by the number of sections for puppies. Therefore, the calculation would be as follows:

Divide the total number of dogs (100) by the total sections (5):
This gives us 20 dogs per section. Multiply this by the number of sections for puppies (1):
This gives us 20 puppies in the kennel.

A fisherman borrowed 85,000 over 25 years at 13.5% p.a. interest compounded monthly. At the end of the seventh year, interest rate climbed to 15% p.a. compound and fisherman's repayments were increased to allow him to complete the repayments by the end of 25 years term.

a. how much did the fisherman owe at the end of the first 7 years?
b. what were his monthly repayments for remaining 18 years?
c. how much interests in total did the fisherman pay at the end of the 25 years long.

Answers

Amount borrowed, A1 = 85,000
Rate, i, for the first 7 years = 13.5% = 0.135
Rate, i, for the remaining 18 years = 15% = 0.15

Part (a): Amount owed after 7 years
Without interest rate, monthly payment, Po= 85,000/(12*25) = 283.33
After 7 years, principal amount remaining = 85,000 - (283.33*7*12) = 61,200.

Therefore, the amount owed after 7 years, A2 = 61,200

Part (b): Monthly repayment for the rest of 18 years
Rate, i = 15% = 0.15

Monthly payment, P(18) = A1*D2
D2 = {0.15/12}/{1-(1+0.15/12)^-12*25} = 0.01281

Then,
P(18) = 85,000*0.01281 = 1088.71

Part (c): Total interest paid
I =[ I(7) + I(18)] - A1

I(7) = P(7)*7*12 + P(18)*18*12

Now, P(7) = A1*D1
D1 = {0.135/12}/{1-(1+0.115/12)^-12*25} = 0.01165

Then,
P(7) = 85,000*0.01165 = 990.25

Therefore,
I = [990.25*7*12 + 1088.71*18*12] -85,000 = 318,341.50 -85,000 = 233,341.50

Eric is getting his mountain climbing cerificate. There are 63 days that Eric climbs for 2 hours, there are 97 days that he climbs for 3 hours. How many more hours does Eric need to climb until he earns a certificate for climbing 500 hours?

Answers

Multiply 63x2= 126 then multiply 97x3=291
126+291=417. he needs 500 hours now you will subtract 500-417=83 he needs 83 more hours to reach 500

Final answer:

Eric's total hours climbed so far are 417 hours. To meet his goal of a 500-hour certificate, he still needs to climb for 83 additional hours.

Explanation:

The question pertains to Eric's mountain climbing practice. To find how many more hours does Eric need to climb to earn his 500-hour certificate, we need to calculate the total hours he has already climbed by multiplying the number of days he climbed by the number of hours he climbed each day.

So, for the 63 days Eric climbed for 2 hours each day, that's 63 * 2 = 126 hours.

And for the 97 days he climbed for 3 hours each day, that's 97 * 3 = 291 hours.

Now, we add these two amounts together: 126 hours + 291 hours = 417 hours.

Since he is aiming for a 500-hour certificate, we subtract the hours he has already climbed from this total: 500 hours - 417 hours = 83 hours

Therefore, Eric needs to climb for 83 more hours to earn his 500-hour certificate.

If the least value of n is 4, which inequality best shows all the possible values of n?

Comment
If the least value of n is 4 that means that 4 is one of the numbers in whatever it is that you are describing. In other words n = 4 is part of your answer. If that is the case, the last two values are incorrect because 4 is not included in either one of them.

Discussion
So that means that you have to choose between one of the first 2. The key word is least. It means that the lowest possible value is 4. Nothing is lower. 

When you write something like n ≤ 4 what you are saying is the n must be = to or less than 4. The arrow head points to the smallest number which, in this case, is n. 

But the question says that the least number is 4. So the arrowhead must point towards the 4. This we have that n must be larger than 4. 

Conditions
There are 2 conditions to this problem
n must be greater than 4
n can equal 4. It is the smallest number.
