Answer:
Step-by-step explanation:
Compute the standard error of the proportion.
sqrt[pq/n] = sqrt[0.2*0.8/100] = 0.04
p = 20%, q = 1- 20%
What is the probability that the sample contains between 12 and 14 business majors?
P(12≤X≤14) = P(X≤14) - P(X≤12)
= binomcdf(100,0.2,14)-binomcdf(100,0.2,11) = 0.0804 - 0.0126 = 0.0679
Answer:
Instead of subtracting 5 from both sides you would need to add because the equation is technically saying 5y - 5 = 10.
Percent change =100%*(new value-old value)/(old value)
If result is positive, it is an increase. If the value is negative it is a decrease.
100%*(50-45)45=100% *(5/45) =11.11 %

Answer:
-9
Step-by-step explanation:
-7x+10x^3-9x^5+3x^2+3
We need to write the terms from highest power to smallest power
-9x^5+10x^3+3x^2-7x+3
The leading coefficient is the number in front of the highest power
-9
The area of the portion of the rectangular field that has crops growing is 4.7 x 10² ft².
<h3>
Area of the rectangle</h3>
The area of the rectangle is calculated as follows;
Area of rectangle = L x b
where;
- L is length of the rectangle
- b is the breadth of the rectangle
Given parameters;
- Length of the rectangle = 3.5 x 10 ft = 35 ft
- Breadth of the rectangle = 2.7 x 10 ft = 27 ft
Area = 35 ft x 27 ft
Area = 945 ft²
<h3>Area of the portion of the field that has crops growing</h3>
Area = ¹/₂ x 945 ft²
Area = 472.5 ft²
Area = 4.7 x 10² ft² (2 significant digits)
The two significant digits was chosen based on the number of significant digits of the rectangle dimensions (that is, the length and breadth are given in 2 significant digits, so the area has to be in 2 significant digits to maintain consistency).
