Answer:

(A)Third degree trinomial

Step-by-step explanation:

The given expression is:

$2x+10x^2-x^3$

Now, Degree of the expression is defined as the highest power of the variable given in the expression, thus in the given expression that is $2x+10x^2-x^3$ the variable is x and the highest power of x is 3, therefore it is a third degree expression.

Also, Trinomial is an expression which consists of three terms, and also the given expression $2x+10x^2-x^3$ consists of three terms that are $2x, 10x^2 and -x^3$ therefore, the given expression is a third degree trinomial.

Thus, option A is correct.

Yes - they have to be similar. Since they are using the same line as the hypotenuse, the ratio of the other two sides are in the same ratio (ie, the slope of the line), the 3 inner angles will be the same. Thus, the triangles will be similar.

Answer:

0.2611 = 26.11% probability that exactly 2 calculators are defective.

Step-by-step explanation:

For each calculator, there are only two possible outcomes. Either it is defective, or it is not. The probability of a calculator being defective is independent of any other calculator, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
