A bag contains 6 red jelly beans, 4 green jelly beans, and 4blue jelly beans. If we choose a jelly bean, then another jelly bean without putting the first one back in the bag, what is the probability that the first jelly bean will be green and the second will be red?

Answers

Answer 1

Answer:

The probability of picking a green jelly bean with the first pick is 4/14 = 2/7, because there are 14 jelly bean in total (6 red + 4 green + 4 blue) and 4 of them are green.

If you pick a green jelly bean at the beginning, you have 13 jelly beans remaining, of which 6 are red. So, the probability of picking a red jelly bean is now 6/13.

You want these two events to happen one after the other, to be more precise you want to pick a green jelly bean with the first pick AND a red jelly bean with the second pick. We know the probabilities of the two events, so we have to multiply them to get the probability of them happening both:

$(2)/(7)\cdot(6)/(13)=(12)/(91)$

Jenny wrote the following expression in her notebook: 2· x + 16·y. Name all of the terms and factors in the expression. Explain the difference between a term and a factor.

Answers

Answer:

In the expression 2·x + 16·y, there are two terms and three factors.

A term in an algebraic expression is a combination of variables and/or constants that are separated by addition or subtraction. In this case, the two terms are 2·x and 16·y. The term 2·x consists of the factor 2 and the variable x, while the term 16·y consists of the factor 16 and the variable y.

On the other hand, a factor is a number or variable that is multiplied by another number or variable. In this expression, the factors are 2, x, 16, and y. The factors 2 and 16 are constants, while x and y are variables.

To summarize:

Terms:

1. 2·x

2. 16·y

Factors:

1. 2

2. x

3. 16

4. y

The difference between a term and a factor lies in their roles within an expression. A term is a combination of factors that are separated by addition or subtraction, whereas a factor is an individual number or variable that is multiplied by another number or variable.

right triangle
from base of triangle to wall=a
from floor to top of ladder on wall=b
legnth of ladder=c

legnth=12=c
base is 3 feet away=a
use pythagorean theorem
a^2+b^2=c^2
3^2+b^2=12^2
9+b^2=144
subtract 9
b^2=135
square root both sides
b=√135=3√15

the height is 3√15 feet

If x is a real number such that $x^3 = 729$ , then $x^2+√(x)$ equals?

Answers

$x^3 = 729 \n \n x^2+√(x) =? \n \n x^3 - 729=0 \n \n x^3-9^3 = 0\n \n(x-9)(x^2+9x+81)=0$

$x^2+9x+81 =0 \ \ or \ \ x-9 = 0\n \n\Delta =b^2-4ac =9^2-4\cdot 1\cdot 81=81- 324 =-243 \n \n and \ we \ know \ when \ \Delta \ is \ negative, \ theres \ no \ solution \n or \n x-9=0 \n \nx=9$

$a^3-b^3=(a-b)(a^2+ab+b^2) \n\n \n x^2+√(x) = 9^2+√(9)=81+3 = 84$
