Answer:
6.38548 years
Step-by-step explanation:
1 = 2 
1/2 =
ln(1/2) = 42k ln(e)
ln(1/2)/42 = k
k = -0.01650
~~~~~~~~~~~~~~
45 = 50 
45/50 =
ln(45/50) = -0.01650 t ln(e)
ln(45/50)/ -0.01650 = t
t = 6.38548 years
A) okay so let x represent how old the friend is now. And 4 represent the years added on. If you have to be LESS then 18 years old to be in boy scouts, and the friend is still able to be in boy scouts after four years, then It can be modeled by x + 4 < 18
B) wrote down number values with 18 being in the middle. Plot a dot on the number 18 (with an open circle. Not filled in circle. A filled in circle means equal to and it is not equal to.) and since you have to be LESS then 18, you should draw a line going left to the smaller numbers of 18.
I hope this helps??
Answer:
The experimental probability of getting a 3 on a die is 30% which is approximately 13% more than its theoretical probability (17%).
Step-by-step explanation:
Theoretical probability of number 3 on a die:
Total no. of possibilities = 6
Probability of getting a 3 on a die each time it is rolled = 1/6
= 0.16667
= 17%
Experimental probability of number 3 on a die:
Total no. of rounds = 4
Rolls each round = 20
no. of 3s in round 1 = 6
no. of 3s in round 2 = 6
no. of 3s in round 3 = 5
no. of 3s in round 4 = 7
Total rolls = 20*4 = 80
no. of times 3 comes up = 6+6+5+7 = 24
Experimental probability of getting a 3 on a die
each time it is rolled = no. of 3s/total rolls
= 24/80
= 0.3
= 30%
Difference = 30% - 17% = 13%
Experimental probability of getting a 3 on a die is 30% which is approximately 13% more than its theoretical probability (17%).
2x - 3y = 13 /*2
x + 2y = - 4 /*(3)
4x - 6y = 26
3x + 6y = - 12
---------------------- +
4x + 3x = 26 - 12
7x = 14
x = 2
y = ( - 4 - x)/2 = ( - 4 - 2)/2 = - 6/2 = - 3
Answer
( 2; - 3)
