n=-5/2
Step-by-step explanation:
Answer:
=3. The remainder of given polynomial is 3.
Let us take polynomial f(x) as dividend and linear expression as divisor.
The linear expression should be in the form of x-a.
Then, the remainder value of polynomial will become f(a).
So, substitute the c value in the polynomial expression and evaluate to get the remainder value.
The perimeter of a rectangle is the sum of twice the length and twice the width. When a diagonal is drawn across the rectangle, two congruent triangles are formed. The legs of the triangle are the sides of the rectangle. Right triangles indicates that we can use the Pythagorean theorem. Let length = xLet width = y Set the equation based on what we know. 2x + 2y = 22 x + y = 11 eq1 x2 + y2 = [√65]2 eq2 We have two equations to work with. x + y = 11 eq1 x2 + y2 = 65 eq2 Substitute eq1 into eq2. From eq1, x = 11 - y x2 = (11 - y)2 x2 = (11 - y)(11 - y) x2 = 121 - 22y + y2 (121 - 22y + y2) + y2 = 65 121 - 22y + 2y2 = 65 2y2 - 22y + 56 = 0 2(y2 - 11y + 28) = 0 2(y - 7)(y - 4) = 0 y = 7 and y = 4 Substitute these y values into eq1 to solve for x. x = 11 - 7 and x = 11 - 4 x = 4 and x = 7 Each pair of solutions has the same dimensions. Shorter side = 4Longer side = 7
The expected number of cars in a randomly selected American household will be 1.75.
Using the probability model, if we ignore some households that own more than 5 cars. Then,
Number of cars Probability
0 0.09
1 0.36
2 0.35
3 0.13
4 0.05
5 0.02
Multiplying each possibility by its probability
∑xP(x)
= 0x0.09+1x0.36+2x0.35+3x0.13+4x0.05+5x0.02
=1.75
Probability is simply the possibility that something will happen. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several. The study of events that fit into a probability distribution is known as statistics. A probability model is a representation of a random occurrence in mathematics. It is defined by its sample space, occurrences, and related probabilities for each event. When choosing a sample from a population using the randomization principle, also referred to as chance or random selection, the procedure is known as probability sampling. Generally speaking, probability sampling is more challenging, expensive, and time-consuming than non-probability sampling.
Note that the full question is:
What’s the expected number of cars in a randomly selected American household?
(a) Between 0 and 5
(b) 1.00
(c) 1.75
(d) 1.84
(e) 2.00
