What’s the value of x in this problem? - 1

Answers

Answer 1
Answer: 120-58=62
So the x is 62
Answer 2
Answer:

Answer:

x = 62 degrees

Step-by-step explanation:

180 - 120 = 60  (For a straight line)

60 + 58 = 118 degrees

180 - 118 = 62  (Angle of triangle - all of the other angles)

Answer:

angle B is 62 Degress angle A is 87 degress D is 87 degress C is 28 degress.

Step-by-step explanation:

I am in geometry btw so i know this stuff and 65 plus 28 is 93 and 180 -93 is 87 so a is 87 and d is 87 too becuase of vertical angles and b is 62 becuase 90 -28 is 62 and c is 28 becuase of vertical angles your wellcome kid good luck!!!!

You are to take a multiple-choice exam consisting of 100 questions with 5 possible responses to each question. Suppose that you have not studied and so must guess (select one of the five answers in a completely random fashion) on each question. Let x represent the number of correct responses on the test. (a) What is your expected score on the exam? (Hint: Your expected score is the mean value of the x distribution.) (b) Compute the variance and standard deviation of x. Variance = Standard deviation =

Answers

Answer:

a) 20

b) Variance 16, standard deviation 4

Step-by-step explanation:

For each question, there are only two possible outcomes. Either you guesses the answer correctly, or you do not. The probability of guessing the answer of a question correctly is independent of other questions. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

The variance of the binomial distribution is:

V(X) = np(1-p)

The standard deviation of the binomial distribution is:

√(V(X)) = √(np(1-p))

100 questions

So n = 100.

You guess

5 options, one correct. So p = (1)/(5) = 0.2

(a) What is your expected score on the exam?

E(X) = np = 100*0.2 = 20

(b) Compute the variance and standard deviation of x.

Variance:

V(X) = np(1-p) = 100*0.2*0.8 = 16

Standard deviation:

√(V(X)) = √(16) = 4

In the following steps student made the error in the third step.

What is an Equation ?

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

The error occurred in Step 3.

Step 3 should be:

-2(m) = -2(6 + n)

-2m = -12 - 2n

The mistake was that the student distributed the negative sign only to the 6 and not to the n.

The correct next step is to simplify equation 2:

2m = 8 + 8n

So the student made an error in Step 3.

Nevaeh took out a 20-year loan for $155,000 at 3.6% interest, compounded monthly. If her monthly payment on the loan is $906.93, how much of her first payment went toward note reduction?A. $441.93

B. $465.00

C. $906.93

D. $326.49

Answers

Answer:

A. $441.93

Step-by-step explanation:

Given that Nevaeh took out a 20-year loan for $155,000 at 3.6% interest, compounded monthly and  her monthly payment on the loan is $906.93

Let us calculate EMI schedule for 155000 for 20 years

Out of EMI 906.93, 441.93 will be for note reduction.

There are four options given as

A. $441.93

B. $465.00

C. $906.93

D. $326.49

Correct answer is option A) 441.93$
