Answer:

-x^2+10x+7

Step-by-step explanation:

3x^2+8x+7-(4x^2-2x). find the difference of the polynomials

First remove the parenthesis by multiplying minus inside the parenthesis.

3x^2+8x+7-4x^2+2x

Now we combine like terms. the terms with same variables and same exponents are like terms.

3x^2-4x^2= -1x^2

8x +2x= 10x

3x^2+8x+7-(4x^2-2x)=-x^2+10x+7

Assume that random guesses are made for seven multiple choice questions on an SAT​ test, so that there are equals 7 ​trials, eac
NeTakaya

Answer: 0.5

Step-by-step explanation:

Formula for binomial probability :-

P(x)=^nC_xp^x(1-p)^{n-x}, where P(x) is the probability of getting success in x trials , n is the total number of trials and p is the probability of getting success in each trial.

Given : The number of trails : n=7

The probability of success​ for each trial : p=0.5

Now, the probability that the number x of correct answers is fewer than 4 will be :-

P(x

Hence, the probability that the number x of correct answers is fewer than 4 = 0.5
