Answer:
miles
Step-by-step explanation:
We have been given that Karleigh walks 5/8 mile to school every day.
To find the distance walked by Karleigh in 5 days we will multiply distance traveled in one day by total number of days.
Therefore, Karleigh walked miles to school in 5 days.
Answer:
Complementary
Step-by-step explanation:
The two angles are complementary because the angles are both a part of a right angle (a 90-degree angle), so they will both add up to 90 degrees, making them complementary.
Hope this helps!
Answer:
The probability is 0.68
Step-by-step explanation:
We are going to use conditional probability to solve this problem.
We define the following events :
A : '' Alex replaced the starter''
B : ''Alex replaced the battery''
M : ''The engine works''
NM : ''The engine doesn't work''
Given two events A and B, we define the conditional probability:
Where P(A,B) = P(B,A) = P(A∩B) = P(B∩A)
In our problem :
Alex replaced the battery or either the starter ⇒
We need to find
We write :
P(M) = [P(M∩B) ∪ P(M∩A)]
P(M) = P(M∩B) + P(M∩A) - P[(M∩B)∩(M∩A)]
But P[(M∩B)∩(M∩A)] = 0 because he replaced the battery or either the starter
P(M) = P(M∩B) + P(M∩A)
P(M)=0.595+0.03
P(M)=0.625
P(NM)= 1-P(M)=1-0.625=0.375
P(NM)= 0.375
P(NM/B) = 1-P(M/B)=1-0.7=0.3
P(NM/B) = 0.3
Hey there! I'm happy to help!
We see that Steve runs 2.5 miles per day and Sam runs 6.5 miles per day. If you add these together, we see that they run 9 miles every day.
We now need to see how many of these 9 mile days fit into this 450 miles. Let's divide 450 by 9 and we will see how many days it will take for them to reach 450 miles combined.
450÷9=50
Therefore, it will take Steve and Sam 50 days to reach 450 miles combined!
Have a wonderful day! :D
