Answer:
Probability = 0.119
Step-by-step explanation:
P (Coronavirus) = P(Person online & corona) or P(Person offline & corona)
(0.70 x 0.02) + (0.30 x 0.35)
0.014 + 0.105
0.119
<u>Answer</u><u>:</u>
(i) = ⅙
(ii) = 1/12
<u>Step-by-step-explaination</u><u>:</u>
Each dice have 6 number
Then for 2 dice the total number is 12
Now,
(i) the same number on both dice.
Probability (P) = no. of outcome ÷ no. of total outcomes
P = 2 ÷ 12 = ⅙
(ii) different numbers on both dice.
Probability (P) = no. of outcome ÷ no. of total outcomes
P = 1 ÷ 12 = 1/12

1) we calculte the driver´s unit rate of speed.
s=speed
d=distance
t=time.
s=d/t
45 miles------------------3/4 hour
x----------------------------- 1 hour
x=(45 miles * 1 hour) / (3/4 hour)=60 miles.
speed or rate=60 miles / 1 hour.
2)we calculate the distance traveled at 1.25 hour.
distance=rate * time
distance=(60 miles /1 hour) * 1.25 hour=75 miles.
Answer: the driver would´t go late, because, the distance is 65 miles, and he can travel 75 miles if he drive with that speed .
One fraction is 2/5.
another one is 12/30.

For this case we have the following equation of motion:
h (t) = -16t ^ 2 + 90t
Equaling the equation to zero we have:
-16t ^ 2 + 90t = 0
We look for the roots of the polynomial:
(t) (- 16t + 90) = 0
t1 = 0 (initial position)
t2 = 90/16 = 5.625 s (time it reaches the ground again)
Answer:
it will return to the ground in:
t = 5.625 s
