3/7 x+5=8
3/7 x=3
3x=21
x=7
The answer is (2)
Answer:
21
Step-by-step explanation:
because i know
Ok this might be wrong but you don’t have much time so I will give my best
I’m pretty sure the of the x and y thing you do this you see the box with the number in it do this the top two says 2 and 4 the left side is x and the right side is y so you see at the bottom of the number Line thing on the right is a little x that where you start so the box of numbers the fist one says 2 so go to the bottom number line and there is the number two now the top right box with numbers says 4 so go up 4 squares from the number 2 and make a dot where they come together
Answer:
A. -1, multiplicity 1; 0, multiplicity 1; 3, multiplicity 1.
Step-by-step explanation:
Let 
, to determine its roots and multiplicities we proceed to factorize the polynomial:
1) 
Given
2) 
Distributive property
3) 
Quadratic formula/Result
The roots and multiplicities of are:
<em>0 (multiplicity 1)</em>
<em>3 (multiplicity 1)</em>
<em>-1 (multiplicity 1)</em>
Therefore, the correct answer is A.
Answer:
P = 0.0008 (non rounded answer is 0.000771605)
Step-by-step explanation:
You first need to determine how many different ways you can roll a 7 using 2 dice. You options are...
First Die Second Die
1 6
2 5
3 4
4 3
5 2
6 1
There are six different ways to roll a 7. If you do the same for all possible numbers, you will see that there are 36 total options when rolling two dice. The first die has six options, and the second die also has 6 options. 6x6 = 36. (This is the fundamental counting principal you have have leared in statistics)
So the chances of rolling a 7 one time with two dice is 1/6. Since repeated rolling of dice is an independent event (any roll has no effect on the next roll), you multiply the probabilities of each event.
So the probability of rolling a 7 four times in a row is
(1/6)(1/6)(1/6)(1/6), which simplifies to 1/6^4, or 1/1296,
Probability is written in decimal form, and usually rounded to 4 decimal places.
1/1296 = 0.000771605, or 0.0008 rounded to 4 decimals
