there are five marbles in a bag. three are green and two are yellow. you draw a marble, replace it, and then draw another. what is the probability of choosing a green marble and then a yellow marble.
Answer: 1/10
Step-by-step explanation:
1: Let’s take out the “DO NOT REPLACE IT.” It can make the whole thing seem harder. Rather, here is this. “There are five marbles in a bag, 3/5 are green and 2/5 are yellow. You DRAW TWO MARBLES. What is the chance of you drawing two yellow marbles?”
2 : Now let’s look at some important information.
100% of marbles= 5 marbles.
60% of marbles= the three green marbles.
40% of marbles= the two yellow ones.
Picking 2 of the 5 marbles will mean taking 40% of the marbles out of the bag.
Simplify: Now, to make it easier, the question is this. what is the chances of the 40% being the same color, Specifically yellow.
3: Let me explain. There are two yellow marbles, you pick out two. That is a one out of five chance of you getting ONE yellow marble the first time. That is 1/5. picking two at the same time results in a 2/5 chance.
4: if you pick twice it would be 1/10 chance.

Answer:
hi there is my android tablet still available for sale and only 50 buks
plzzz help! what expersion is equivalent to it?
Answer:
[tex]64x^{12}[/tex]
Step-by-step explanation:
We have to use the law of indices for finding the equivalent expression.
[tex](8x^{5})^{2} = 64x^{10}[/tex] We square 8, which is 64 and multiply the two powers.
[tex](x^{4})^{\frac{1}{2}} = x^{2}[/tex] We multiply the 2 powers giving us, [tex]\frac{4}{2}[/tex], which simplifies to 2.
[tex]64x^{10}[/tex] × [tex]x^{2}[/tex] = [tex]64x^{12}[/tex] This is the answer as we multiply the two indices together.
I hope this helps!! ^-^
Answer:
64x¹²
Step-by-step explanation:
(8x^5)^2 × (x^4)^1/2
64x^10 × (x^4)^1\2
64x^10 × x^2
Calculate:
64x^12

These are questions about triangles. The teacher has already done one but I don’t know how to do the rest. Please help me! :(
Step-by-step explanation:
To help you, Remeber the SOHCAHTOA rule
When It asked to find sin, cos, tangent of a angleIf you finding the sin of a angle you must find the side that is Opposite then put it over the hypotenuse I'll do 3,6,7,8 for you.
For 3,The side that is opposite of c is 28 and the hypotenuse (which is the longest side of the triangle) is 35. So the answer is 28/35. or 4/5.
For 6, 32 is opposite of A and 40 is the hypotenuse so
32/40 or 4/5 is our answer.
For 7, 24 is opposite of Z and 40 is the hypotenuse so
24/40 or 3/5 is the answer.
For 8, 14 is opposite of Angle C and 50 is our hypotenuse so
14/50=7/25 is our answer
COS
To find cos it is adjacent/hypotenuse
For 2 the adjacent side to C is 16 and the hypotenuse is 34. so our answer is 16/34 or 8/17.
For 5, the adjacent side is 30 and the hypotenuse is 34 so our answer is 30/34 or 15/17
For 9, the adjacent side is 24 and hypotenuse is 30 so our answer is 24/30 or 5/6.
TAN
TO FIND TAN, it is Opposite/Adjacent
4, the opposite side is 32 and the adjacent is 24 so our answer is 32/24 or 4/3.
10, the opposite side is 27 and the adjacent is 36 so our answer is 27/36 or 3/4
What numbers correctly complete each equation?
All squares have the same value
the first one is 5.25 . you have to divide 10.5 by 2 and you'll get 5.25 and when you add 5.25 twice you'll get 10.5 which is the same as 10.50

receding means to move farther away from previous position
so the equation would be
3-.75t
or
-.75t + 3

PLZ HELP!!!! solve for x
Answer:
64 degrees
Step-by-step explanation:
Combining the 90 degrees, x degrees, and 26 degrees creates a flat angle or 180 degrees
so first, combine 90 and 26 degrees
90+26= 116
then subtract 116 from 180
180-116= 64 degrees
