The answer is 18, work shown in image attached
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The number of members is n = 15
Generally the number of ways of selecting two member from the fifteen members is mathematically represented as

Here C stands for combination hence we will be making use of the combination functionality in our calculator

=> 
=> 
Gnerally the number of outcome that matches the outcome required by the committee(Which is reselecting the member who where the chairman and vice chairman of the board ) is m = 1
Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as

=> 
=>
=>
Answer:
11
Step-by-step explanation:
2+75= 7y
77 = 7y
77/7 = 7y/7
y = 11
In miles 365 million miles or 365,000,000
in km, 588 million km or 588,000,000
so
scientific notation=(number less than 10 and greater than or equal to 1) times 10^n
so
we need to move the decimal point 8 spaces to the left
to compensiate for that, we multiply by 10⁸ which will move it 8 to the right
so
365,000,000 mi=3.65 times 10⁸ mi
588,000,000 km=5.88 times 10⁸ km
those are the distances in scientific notation
Answer:
<u>20.4minutes</u>
Step-by-step explanation:
<em>Duration= Number of words/Typing speed</em>
<em>Duration</em><em>=</em><em> </em><em>100</em><em>0</em><em>/</em><em> </em><em>49</em><em> </em><em>per</em><em> </em><em>min</em>
<em>=</em><em> </em><em>20.4minutes</em><em> </em>
