Brandon:
About 1 book
Alyssa:
7/12 of a book
Brandon:
4/5 of a book
Step-by-step explanation:
Alyssa:
1/4=1/2
1/3=1/2
1/2+1/2-1
1/4= 3/12
1/3=4/12
3/12+4/12=7/12
Brandon:
2/5=1/2
4/10=1/2
1/2+1/2=1
2/5=4/10
4/10+4/10=8/10=4/5
Hope this helps! Please mark as brainliest!
Answer:
R=-12
Step-by-step explanation:
6(1 + 3R) = 2(10R - 9) -4R
Distribute 6 through the parentheses
6+18R=2(10R-9)-4R
Distribute 2 through the parentheses
6+18R=20R-18-4R
Collect like terms
6+18R=16R-18
Move the variable to the left-hand side and change its sign
6+18R-16R=-18
Move the constant to the right-hand side and change its sign
18R-16R=-18-6
Collect like terms
2R=-18-6
Calculate the difference
2R=-24
Divide both sides of the equation by 2
R=-12
if you'd make me brainliest that'd be great, if not its ok as well! I hope this helped!!!
Answer: All four runners ran .96 seconds
Step-by-step explanation: The total time of the four runners, divided by the amount of runners.
3.86/4= .965
The value of the probability P(E and F) is 0.2802
<h3>Independent probability</h3>
Events are known to be independent if the occurrence of one does not affect the other.
Given the following parameters
P (E) =0.471
P(F) = 0.595
If E and F are independent, then;
P(E and F) = P(E)P(F)
P(E and F) = 0.471 * 0.595
P(E and F) = 0.2802
Hence the value of the probability P(E and F) is 0.2802
