Option BAnswer:
b) Since the y-values increase as the x-values increase, the scatter plot shows a positive association.
Step-by-step explanation:
In a scatter plot:
The explanatory (independent) variable is along the x-axisThe response (dependent) variable is along the y-axisCorrelation measures how closely two variables are linked.
Positive correlation: response variable increases as the explanatory variable increasesNegative correlation: response variable decreases as the explanatory variable increasesThe given scatter plot shows the y-variable increasing as the x-variable increases. Therefore, this shows a positive correlation.
Therefore, the solution is:
b) Since the y-values increase as the x-values increase, the scatter plot shows a positive association.
Sand Hill Crane Elementary is
collecting food to donate. Their goal
is 2 tons of food so far they have
collected 2,798 pounds of food.
How many more pounds of food do
they need to collect?
The pounds of food that Sand Hill Crane Elementary needs to collect more in order to reach their goal is 1202 pounds.
How many more pounds needs to be collected?The first step is to convert tons to pounds.
1 ton = 2000 pounds
2 tons x 2000 = 4000 pounds.
The second step is to subtract the pounds of food collected so far from the goal.
4000 - 2798 = 1202 pounds.

Muna claims that the expression (8)(16) + (8)(12) + (16)(12) represents the
surface area, in square inches, of the right rectangular prism shown. Is Muna
correct? Explain.
The surface area of a right rectangular prism is the amount of space on it.
Muna's claim is incorrect
How to determine the surface area?
The surface area of a right rectangular prism is calculated as:
A = 2 * (lw + lh + wh)
So, we have:
A = 2 * (8 * 16 + 8 * 12 + 16 * 12)

A container manufacturer plans to make rectangular boxes whose bottom and top measure 4x by 3x. The container must contain 48in.3 The top and the bottom will cost $1.80 per square inch, while the four sides will cost $3.70 per square inch.
What should the height of the container be so as to minimize cost? Round your answer to the nearest hundredth.
The height of the container that will be able to minimize the cost will be 3.08cm.
How to calculate the height?The volume of the box will be:
= (3x)(4x)h
= 12x²h
From the information given, we are told that the container must contain 48in³. Therefore,
48 = 12x²h
h = 4/x²
The function cost will be:
= 3.50(2)(12x²) + 4.40(14x)h
= 84x² + 61.6x(4/x²)
= 84x² + 246.4/x
We'll use the first derivative. This will be:
dC/dx = 168x - 246.4/x²
x = 1.14.
Therefore, the height will be:
h = 4/x² = 4/1.14² = 3.08cm
In conclusion, the height is 3.08cm.

Prove that y=sin(x) then dy/dx=cos(x)
Step-by-step explanation:
You will have to use the limit defition of the derivative. Brainly does not have calculus symbols, which is very unfortunate, so I can only use my words. Take the limit as the change in 'x' approaches zero. You will have:
[tex] \frac{sin(x + {x}^{.} ) - sin(x)}{ {x}^{.} } [/tex]
If you let "x dot" equal zero as the limit requires, you will get 0/0 which is indeterminate. Break up the first term using the formula for the sine of a sum. You get:
[tex] \frac{sin(x)cos( {x}^{.} ) + sin( {x}^{.})cos(x) - sin(x) }{ {x}^{.} } [/tex]
Factor a sin(x) from the first and third term to get:
[tex] \frac{sin(x)(cos( {x}^{.}) - 1 ) + sin( {x}^{.})cos(x) }{ {x}^{.} } [/tex]
Use the linearity to break the limit into two parts:
[tex] \frac{sin(x)(cos( {x}^{.}) - 1 )}{ {x}^{.} } + \frac{sin( {x}^{.} )cos(x)}{ {x}^{.} } [/tex]
First term converges to zero, second term converges to cosine. Therefore proving the derivative of sine is cosine

meter, the distance from the ship to the ocean floor
Determine, to the nearest meter, the distance o
rom the anchor to where the boat is perpendicular to ground.
The distance between the boat and the ocean's floor is 19m
How to get the distance from the ship to the ocean's floor?
We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.
We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).
Then we use the relation:
Sin(a) = (opposite cathetus)/(hypotenuse).
Replacing the values that we know, we get:
Sin(39°) = d/30m
sin(39°)*30m = d = 18.9m ≈ 19m
The distance between the boat and the ocean's floor is 19m.
