So the chance of getting 1 blue marble is 30% or 3/10, the chance of getting another in a row is also 3/10 since its asking for both youd do 3/10*3/10 = 9/100
Answer:
0.25
Step-by-step explanation:
Order of operations: the rules of which calculation comes first in an expression.
They are: PEMDAS
<span><span>Do everything inside parentheses first: ()
</span><span>then do exponents: x2
</span><span>then do multiplies and divides from left to right
</span><span>lastly do the adds and subtracts from left to right</span></span>
Since the first term in the equation is
, you know that each group you make will have to have an x in it. Now, you need to figure out what times what equals 7 and adds up to 8. You can list all of the numbers that multiply to seven until you find the right numbers.
-1 x -7
1 x 7
1 and 7 add to eight and multiply to seven, so those will be the numbers in your groups. This makes your factored groups
(x + 1)(x + 7).
