Answer:
7. 7.1+5.4+2.9=15.7
10.3+5.4=15.7
8. 373.4 - 152.9 = 220.5
373.4 - 153 = 220.4
220.4 - 0.1 = 220.5
9. 18.25 + 7.99 + 4.75 = 30.99
10. 1.05 + 3 + 4.28 + .95 = 9.28
11. 302.504
12 50.5
Answer:
So, the probability is P=0.041.
Step-by-step explanation:
We know that 45% of people in Fast-Food restaurants order a diet drink with their lunch.
We conclude that the probaility p=0.45 that a person order a diet drink.
We calculate the probability that the fourth person orders a diet drink.
We get:
So, the probability is P=0.041.
Answer:
12.1
Step-by-step explanation:
Let the number be " x ".
The sum of a number and 2.6,
x + 2.6
1/3 times the sum of a number and 2.6
1/3 * ( x + 2.6 ) = ( x + 2.6 )/3
1/3 times the sum of a number and 2.6 is 4.9
( x + 2.6 )/3 = 4.9
x + 2.6 = 4.9 * 3
x + 2.6 = 14.7
x = 14.7 - 2.6
x = 12.1
Therefore,
the number is 12.1
The 20th expression would be 80. Counted on my fingers xD hit 80 when i did 20 fingers. which means that if you put 20 as n, it should come out to 80, but it comes out to 84 by the answer you chose, so I'm wondering if the answer you chose was right, or if it was A
