Answer:
1/2
Step-by-step explanation:
Since this die has 6 sides, for each roll it has 6 outcomes.
Hence the probability of it landing on any specific number is 1/6.
Since there are only 3 outcomes wanted (roll less than 4 so it can be 1, 2, or 3) then we have to add the probability of each number being rolled so that is:
1/6 chance of rolling1
1/6 chance of rolling2
1/6 chance of rolling3
1/6 + 1/6 + 1/6
=3/6
=1/2
Answer:
after 11.07secs
Step-by-step explanation:
Given the height of an object modeled by the equation
H = 16T² - 1960
The height of the object on the surface of water is zero, hence H = 0
Substitute
0 =16T² - 1960
Swap
16T² - 1960 = 0
16T² = 1960
T² = 1960/16
T² = 122.5
T = 11.07
Hence the rock will hit the surface of the water after 11.07secs
2 over 9 because if you see there are 3 red and 4 blue
<span>1/12+3/8y=5/12+5/8y
</span><span>3/8y- 5/8 y = 5/12- 1/12
-2/8y = 4/12
-1/4y = 1/3
y = 1/3 *(-4)
y = - 4/3</span>
