Answer:
-1/12
please mark brainliest it would help me a lot ❤️
Step-by-step explanation:
9 5/6 = 9 10/12
1 1/4=1 3/12
9 10/12+1 3/12=14 1/12
Answer:
(a.) On line 4, Travis subtracted $188 from $180 and got a positive answer. The difference should be -$8.00.
(b.) <em>(work provided in picture)</em> To get his account back to 0, Travis needs to deposit $21.80 or more to avoid another overdraft fee.
the equation of the line is
y = -3x + 6
slope is m = -3
as we know that for parallel lines, the slope is always equal.
so the slope of the new line is also m = -3
it is also passing through (-4,9)
so the equation of the line i s
m= -3
so the answer is y = -3x - 3
Answer: The probability of selecting at least one boy (the probability that the 2 students selected are not both girls) is 62/95 or 0.6526
Step-by-step explanation:
From the question, the students to be chosen must be selected from a group of eight boys and twelve girls. This means that the total number of students that these two students must be chosen from is:
8 + 12 = 20 students.
The next step would be to find the probability of selecting a boy:
= Total number of boys/Total number of students
= 8/20
We will also find the probability of selecting one girl from the group
= Total number of girls/Total number of students
= 12/20
To find the probability that the two selected students are not girls is the same as finding the probability of selecting at least one boy. To do this, we will first find the probability of choosing all girls and then subtract it from 1.
The probability of selecting or choosing 2 girls (without replacement)
(12/20) × (11/19)
= 132/380
= 33/95
Then, the probability of selecting at least one boy (the probability that the students chosen are not both girls)
= 1 - (33/95)
= (95/95) - (33/95)
= 62/95 or 0.6526
Answer:
1.5 gallon per day
Step-by-step explanation:
As given,
Daily miles = 42
Average gasoline used = 28 mil/gallon
Daily use of gasoline = 
= 
= 1.5 gallon /day
∴ we get
she conserve gasoline a day = 1.5 gallon per day
