<h3>
Total 73 times we can expect white or gray marbles.</h3>
Step-by-step explanation:
Total number of marbles = 33
Number of white marbles = 6
Number of gray marbles = 5
Now, as we need to pick white or gray marbles, so favorable outcomes
= 6+ 5 = 11 marbles
Now, P(Picking out 1 white or gray marble) = 
Here, the same experiment is repeated 220 times.
So, the Combined Prediction
= Probability at first attempt x Number of repetitions
⇒The combined prediction after 220 attempts = 73
Hence, total 73 times we can expect white or gray marbles.
Answer:
x = -2
x= -3
Step-by-step explanation:
x 2+5x+6=0
To solve the equation, factor x^2+5x+6 using formula x^2+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.
a+b=5
ab=6
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 6.
1,6
2,3
Calculate the sum for each pair.
1+6=7
2+3=5
The solution is the pair that gives sum 5.
a=2
b=3
Rewrite factored expression (x+a)(x+b) using the obtained values.
(x+2)(x+3)
To find equation solutions, solve x+2=0 and x+3=0.
x=−2
x=−3
Answer:
day 14 , 450 dollars
Step-by-step explanation:
We called x is the number of days
Zippy Rent-a-car: 25x + 100
Speedy Rent-a-car: 30x + 30
25x + 100 = 30x + 30
25x -30x = 30 - 100
-5x = -70
x = 14
Answer:
119 is the answer
Step-by-step explanation:
use sum of angles on a straight line
Y = mx + b
in this case m = 2 and b = 1 so
equation
y =2x + 1
hope this helps
