Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 × 
× 
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 × 
× 
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 × 
+ 15C5 ×
P = ( 15C8 + 15C5 )
P = ( ( 
) + ( 
) )
P = ( 6435 + 3003 )
P = ( 9438)
P = 
( 4719)
P = 
P = 0.29
Answer:
None of the above
Step-by-step explanation:
-9 tells the distance between her hand and the keys
The restrictions for the equation is that the denominator can not be zero. So the restrictions for x would be what values make the denominator zero.
7x^2 + 6x = 0
factor
x(7x + 6) = 0
multiply any number by 0 and you get 0. So either x = 0 or 7x+6 = 0
since there's a x in the numerator x/x = 1 so this will not be a restriction. Then the only restriction is:
7x+6 = 0
7x = -6
x = -6/7
Answer:
$356
Step-by-step explanation:
To solve this problem, use this: (200 * 3.78) - (200 * 2)
(200 * 3.78) - (200 * 2)
<em>200 * 3.78 is the same as 2 * 378, which is 756.</em>
756 - (200 * 2)
<em>200 * 2 is the same as 4 * 100, which is 400.</em>
756 - 400
<em>Subtract 400 from 756 to get 356.</em>
356
If they brought the pizza last week, the school could have saved $356.
