63% of all people in the United States have at least some college education. If ten people were chosen at random, find the probability that exactly half have some college education.

Answers

Answer 1

Answer: 0.2417

Step-by-step explanation:

- 10! / (10-5)!5! x 0.53^5 x 0).47^5

Answer 2

To solve the problem we must know Binomial distribution.

The probability that exactly half have some college education is 17.3425%.

Given to us

The probability of a person having at least some college education = 63% = 0.63

To solve the problem we will use the Binomial distribution, therefore,

The probability of a person having at least some college education, p = 63% = 0.63The probability of a person not having at least some college education, q = 37% = 0.37Number of people selected for college education (Sample Size) = 10

Using the formula for Binomial Distribution,

We want the probability that exactly half have some college education, therefore, x = 5

[tex]P(x) = ^nC_x\ p^x\ q^{(n-x)}[/tex]

Substitute the values we get,

[tex]P(5) = ^{10}C_5\ (0.63)^{5}\ (0.37)^{(10-5)}\\\\P(5) = ^{10}C_5\ (0.63)^{5}\ (0.37)^{5}\\\\P(5) = 0.173425 = 17.3425\%[/tex]

Hence, the probability that exactly half have some college education is 17.3425%.

They are asking us to find the determinant

Now using the above formula it becomes

[tex]\left|\begin{array}{c c} sin20\degree & -cos20\degree \\ sin70\degree & cos70\degree \end{array}\right| \: = sin20 \degree cos70 \degree - ( - cos20 \degree sin70 \degree) \: \\ \\ = sin20 \degree cos70 \degree + cos20 \degree sin70 \degree [/tex]

Now using the formula

Find the y-intercept and x-intercept of the line.
5x-3y=10

Answers

y intercept = -10/3
x intercept = 2
the solution is in the pic below
(Sorry if it’s wrong!)

Answer:

strategy:  put this equation into slope intercept form  y = mx + b

then it is easier to find x and y intercepts

Step-by-step explanation:

5x-3y=10

5x-10=3y

5/3x - 10/3 = y

y = 5/3x - 10/3

when x is zero then y is - 10/3, that's the  y intercept

when y is zero then x is 2,  that's the x intercept

Consider the following triangle side lengths and determine if the triangle could exist. Justify your answer. Part A: 21,18,17 Part B: 3,12,8

Answers

Answer:

A yes, B no

Step-by-step explanation:

The triangle inequality states that the sum of any 2 sides of the triangle must be greater than the third side.

A Given 21, 18, 17 , then

21 + 18 = 39 > 17

21 + 17 = 38 > 18

18 + 17 = 35 > 21

Thus the triangle could exist

B Given 3, 12, 8 , then

3 + 12 = 9 > 8

3 + 8 = 11 < 12 ← fails the test

Thus the triangle does not exist
