"If we assume that 57% of Americans says that GM foods are generally unsafe to eat, then there is an 8.8% chance that random sample results will show 60%or more who says that GM foods are generally unsafe to eat" is valid interpretations of this p-valid.
Given info;
Genetically modified foods: A 2016 Pew Research survey found that 56% of Americans believe that eating genetically modified (GM) food is generally harmful. This month, a survey of 500 randomly chosen American citizens found that 60% believe gm foods are typically dangerous to consume. We examine the possibility that more people than 56% believe that eating GM food is generally unsafe this year. 0.084 is the p-value.
If we assume that 57% of Americans say that GM foods are generally unsafe to eat, then there is an 8.8% chance that random sample results will show 60% or more who say that GM foods are generally unsafe to eat” is a good interpretation of the P-value.

Raul baked a loaf of pumpkin bread that is 9 inches long. Each day, he cuts off a half-inch slice of the bread to have as dessert. Raul claims that the remaining length of pumpkin bread varies inversely with the number of slices of pumpkin bread he cuts and eats.
Write an equation that gives the remaining length of pumpkin bread p (in inches) as a function of the number of slices s that he cuts and eats.
Enter the correct expression in the box.
p = ___
Note: I'm not sure about the answer, but it is not an inverse variation function.
Answer: p = 9 - 0.5s
Optionally you can replace 0.5 with the fraction 1/2
===================================================
Explanation:
s = number of slices
0.5s = total width of all of those slices mentioned
9-0.5s = amount left over.
For example, if he eats s = 4 slices then he has eaten 0.5s = 0.5*4 = 2 inches of bread, and there are 9-2 = 7 inches left.
Notice how 9-0.5s=9-0.5*4 = 9-2 = 7.
The equation p = 9 - 0.5s is not an inverse variation because it's not in the form p = k/s, where k is some constant.

dt
=-16, x= 4, y = -1.
For the given function 4xy-4x+4y³ = -36 , value of dy/dt for the condition dx/dt = -16 , x= 4, y= -1 is equal to dy/dt = -32/7.
As given in the question,
Given function is equal to :
4xy-4x+4y³ = -36
Let us consider x and y are function of t.
Now , evaluate the derivative of function with respect to t we get,
4x(dy/dt) + 4y(dx/dt) -4(dx/dt) + 12y²(dy/dt) = 0
⇒( 4x + 12y² ) (dy/dt) + ( 4y -4 ) (dx/dt) = 0
Substitute the value of dx/dt = -16, x = 4 , y = -1 we get,
[ 4(4) + 12(-1)² ](dy/dt) + [ 4(-1) - 4 ] (-16) =0
⇒(16 +12) (dy/dt) + (-8)(-16) = 0
⇒ dy/dt = - ( 8× 16)/ 28
⇒ dy/dt = -32/7
Therefore, for the given function 4xy-4x+4y³ = -36 , value of dy/dt for the condition dx/dt = -16 , x= 4, y= -1 is equal to dy/dt = -32/7.
The complete question is:
Assume x and y are functions of t. Evaluate dy/dt , for 4xy-4x+4y³ = -36, with the conditions dx/dt = -16 , x = 4 , y = -1.

A mathematical function called an exponential function is employed frequently in everyday life. It is primarily used to compute investments, model populations, find exponential decay or exponential growth, and so forth. You will discover the formulas, guidelines, characteristics, graphs, derivatives, exponential series, and examples of exponential functions in this article. The formula for an exponential function is f (x) = axe, where x is a variable and an is a constant that serves as the function's base and must be greater than 0. The transcendental number e, or roughly 2.71828, is the most frequently used exponential function base.
With the highest power in exponential function,
function will be more greater if the numbers multiplied by exponential function are in same order of decimal number.
In given Que,
numbers multiplied are all of 2 decimal number.

A triangle is cut from a rectangle. The height of the triangle is half of the unknown side length s. The area of the shaded region is 84 square inches. Write an equation you can use to find the side length s.
The equation that can be used to find the side length of the shape is 14s - 7s/2 = 84
How to calculate the length?From the information, the two sides of the rectangle are 14 and s.
Area of a rectangle = length × width
The triangle is cut from the rectangle, the height is s/2 and the base is 14.
The area will be: = 1/2 × base × height
= 1/2 × 14 × s/2
= 7s/2
The area of shaded part will be;
= Area of rectangle - Area of triangle
= 14s - 7s/2
Since area is 84, the equation is 14s - 7s/2 = 84.

solve the simultaneous equation F-2g+3=2f-39+2=1
The value of f is 19 and the value of g is 10.5 after solving the simultaneous equation, f-2g+3=2f-39+2=1 .
According to the question,
We have the following equation:
f-2g+3=2f-39+2=1
Now, we will equate both these equations to 1:
f-2g+3 = 1
Subtracting 3 from both sides:
f-2g = 1-3
f-2g = -2 ..(1)
2f-39+2 = 1
2f -37 = 1
Adding 37 to both sides:
2f = 1+37
2f = 38
Dividing by 2 on both sides:
f = 38/2
f = 19
Putting this value of f in equation 1:
f-2g = -2
19-2g = -2
-2g = -2-19
-2g = -21
g = 21/2
g = 10.5
Hence, the value of f is 19 and the value of g is 10.5 after solving the simultaneous equation, f-2g+3=2f-39+2=1.

What is the cross-multiplication method?The denominator of the first term is multiplied by the numerator of the second term when utilizing the cross-multiplication method.
In mathematics, more specifically in elementary arithmetic and elementary algebra, one could cross-multiply an equation between two fractions or rational expressions to make the equation easier or to determine the value of a variable.
So, the value of x will be:
Use the cross-multiplication method as follows:
2x-7/4 = x+3/3
3(2x-7) = 4(x+3)
6x - 21 = 4x + 12
2x = 12 + 21
