Answer:
The probability is 1/9
Step-by-step explanation:
The probability of rolling a 5 the first time is 1/6
The probability of rolling a number greater than 2
Numbers greater than 2 are 3, 4, 5, 6
So the probability of rolling a number out of these four is 4/6
So the probability of rolling a five for the first time and the probability of rolling a number greater than 2 the second time will be
1/6 * 4/6 = 4/36 = 1/9
Answer: 9.7 seconds
Step-by-step explanation:
![16t^2=1503\\\\t^2 =\frac{1503}{16}\\\\t=\sqrt{1503/16} \text{ } (t > 0)\\\\t \approx 9.7](https://tex.z-dn.net/?f=16t%5E2%3D1503%5C%5C%5C%5Ct%5E2%20%3D%5Cfrac%7B1503%7D%7B16%7D%5C%5C%5C%5Ct%3D%5Csqrt%7B1503%2F16%7D%20%5Ctext%7B%20%7D%20%28t%20%3E%200%29%5C%5C%5C%5Ct%20%5Capprox%209.7)
Step-by-step explanation:
2 : 3 = 6 : x ,
Ratio can be written as
2*3 = 6, we multiply top and bottom of fraction by 3
So value of x=9
4 : 7 = x : 42 ,
7*6 = 42, we multiply top and bottom of fraction by 6
So value of x=24
2x : 48 = 3 : 12,
\frac{3}{12}[/tex] =
2x= 12, so x= 6
12 : 15 = x : 20
,
we multiply top and bottom by 4/3
![12 * \frac{4}{3} = 16](https://tex.z-dn.net/?f=12%20%2A%20%5Cfrac%7B4%7D%7B3%7D%20%3D%2016)
So value of x=16
