<span>We expect 150 defects out of the 10,000 cars if the 3 defects out of the 200 cars sampled is representative of all 10,000 cars. First, let's set up the proportions. We have 3/200 cars with defects and we want to know X for X/10000. So 3/200 = X/10000 Now solve for X. 3/200 = X/10000 10000*3/200 = 10000 * X/10000 30000/200 = X 150 = X So the answer is: We expect 150 defects out of the 10,000 cars if the 3 defects out of the 200 cars sampled is representative of all 10,000 cars.</span>

A house on the land measures 45 feet by 38 feet,a wooded area covers 118 feet by 60 feet,and the front yard is 78 feet by 40 fee
Mekhanik [1.2K]
The figure is composed of 2 shapes. A rectangle and a right triangle.

Area of the Rectangle = 600 ft * 200 ft = 120,000 ft²
Area of the right triangle = (600 ft * 450 ft)/2 = 270,000 / 2 = 135,000 ft²

Total area = 120,000 ft² + 135,000 ft² = 260,000 ft²

Area of the house = 45 ft * 38 ft = 1,710 ft²
Area of the woods = 118 ft * 60 ft = 7,080 ft²
Area of the front yard = 78 ft * 40 ft = 3,120 ft²

Area of farmed land = 260,000 - 1,710 - 7,080 - 3,120 = 248,090 ft²

248,090 ft² * 1acre/43,560 ft² = 5.695 acres

Could somebody please help me with this?
BARSIC [14]

For this problem, we are going to use the Remainder Theorem. This says that for x - n to be a factor of a polynomial p(x), then p(n) = 0. Essentially, it says that x - n is a factor if when you substitute n into the polynomial you get a result of 0.


Thus, in our case, when we substitute x = 2 into the polynomial, we should get an answer of 0 if x - 2 is a factor of the polynomial. Given this information, we can solve for c:

p(2) = 2^3 - 4(2^2) + 2c + 2 = 0

8 - 16 + 2c + 2 = 0

2c - 6 = 0

2c = 6

c = 3


The solution is c = 3.
