Answer:
16/25
Step-by-step explanation:
Given
Number of green marbles = 9
Number of White marbles = 17
Total number of marbles = 26
Probability of picking a white marble = 17/26
When a white marble is picked without replacement,
Probability of picking another white marble after first picking a white marble
= 16/25
= 0.64
This is because the total number of marbles would have reduced from 26 to 25 and the number of white marbles from 17 to 16.
<h3>
The deposited sum of money by Edwin is $350.</h3>
Step-by-step explanation:
Let us assume that the amount deposited = P
The rate of interest = 1.4%
The Simple Interest earned = $24.50
Time = T = 5 years
Now, as we know:
SIMPLE INTEREST = 
Hence, the deposited sum of money by Edwin is $350.
Can’t help DDDD: bcoz link is a scam
Since we don't know where to start, we can always give that a variable which in this case, it's X. Since we are finding the sum of three consecutive odd numbers, we will be skipping numbers so we can add 2 each time. Now, let's set up an equation.
<h2>
X + X + 2 + X + 4 = 159</h2><h2 /><h2>
3x + 6 = 159</h2><h2>
-6 -6 ← subtract 6 on both sides</h2><h2 /><h2>
3x = 153</h2><h2>
÷3 ÷3 ← divide both sides by 3</h2><h2 /><h2>
X = 51</h2><h2>
X + 2 = 53</h2><h2>
X + 4 = 55</h2><h2 />
Therefore, the smallest of our three consecutive integers is 51.
