A scientist wants to know if the color of the water affects how much animals drink. The average amount of water each animal drinks was recorded in milliliters for a week and then graphed. Is there evidence to suggest an association between water color and animal?
Answer:
Yes, there is very clear evidence to suggest or show a correlation between
watercolour and each animal's response to the water as well as their total responses.
Explanation
When the water was blue, the total water consumed by both animals came to 1410 ml. The dog consumed more water than the cat. The dog drank 1200 ml while the cat drank just 410 ml.
When the color of the water was changed to green, the animals drank a total of 1300 ml. The cat drank 200 ml while the dog drank 1100 ml.
We can thus, establish that there is an association between the color of the water and the volume of water taken by each animal because on the whole, both animals seem to prefer blue water. They drank more water when its color was blue and less when it was red.

Attached is the complete question with the semi circular design.
Answer:
9.8 m²
Step-by-step explanation:
From the image, we can see that;
Diameter = 5 m
That means radius; r = 5/2 = 2.5 m
Now, formula for area of semi circle is;
A = ½πr²
A = ½ × π × 2.5²
A = ½ × 22/7 × 6.25
A ≈ 9.8 m²
Area of semi circular lawn = 9.8 m²

Write an equation, in standard form, using the following given info: M = 10
and it passes through the point (6,2) *
-10x + y = -58
-10x + y = 58. -10x - y = -58
10x + y = -58
Given:
m = 10
The line passes through the point (6,2).
To find:
The equation of line in the standard form.
Solution:
If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
The line passes through the point (6,2) and m = 10. So, the equation of line is
[tex]y-2=10(x-6)[/tex]
[tex]y-2=10x-60[/tex]
[tex]y-10x=-60+2[/tex]
[tex]-10x+y=-58[/tex]
Therefore, the correct option is A.

Step-by-step explanation:
A sweater is on sale for 12% off. The sale price is $44.00. What is the original amount of the sweater?
==================================================
Work Shown:
x = original price
y = sale price
d = discount = amount saved
d = 12% of x = 0.12x
y = x - d = x - 0.12x = 0.88x
Note how 0.88 = 88%, and this represents the percentage you have to pay if you get 12% off.
We're told the sale price is y = 44, so this leads to...
y = 0.88x
44 = 0.88x
0.88x = 44
x = 44/0.88
x = 50
The original price was $50
---------------------
Check:
If the original price was $50, then the amount you save is 0.12*50 = 6 dollars, which is the discount.
The sale price is 50-6 = 44 dollars which matches up with what your teacher gave you. The answer is confirmed.

What is the value of n?
Answer:
B. 85 degrees
Step-by-step explanation:
To find the top angle inside the tringle, do 180-133 = 47. To find the angle on the left, do 180 - 142 = 38. Do 180 - 47 + 38 = 95 to find the final angle. Then do 180-95 = 85 to find the angle wanted. This is all about using lines, because the angles on both sides of the line must add to 180 if one of the lines they lie on is the same. Hope this makes sense.

Answer:
jndcxiaojdncijadmcijwmqdijxcmc
Step-by-step explanation:
A possible error is (c) C.12×4 does not equal 13.
How to determine why he might be wrongFrom the question, we have the following parameters that can be used in our computation:
Rate = 1/3 miles in 4 minutes
When converted to unit rate, we have
Rate = 1/3 miles/4 minutes
Evaluate the quotient
So, we have
Rate = 1/12 miles per minute
This means that a possible error is (c) C.12×4 does not equal 13.
