Step-by-step explanation:
0.75 x 5= $3.75
$3.75/0.25= 15 quarters
Answer: mean- 38
median- 37
mode- no mode
range- 30
Step-by-step explanation:
The vehicle be able to cover the full distance of 340km with on petrol tank if the petrol usage is 14 km/1.
Since the vehicles petrol tank has a capacity of 40 litres and the bvehicles wants to cover a distance of 340 with a pertol usage of 14 km/l.
We need to determine if the petrol in the tank will be enough to cover that distance.
<h3>Distance</h3>
So, distance = petrol usage × volume of tank
Since
- petrol usage = 14 km/l and
- volume of tank = 40 l,
Substituting the values of the variables into the equation, we have
distance = petrol usage × volume of tank
distance = 14 km/l × 40 l
distance = 560 km
Since the distance covered = 560 km which is greater than 340 km, the vehicle will be able to cover the full distance.
So, the vehicle be able to cover the full distance of 340km with on petrol tank if the petrol usage is 14 km/1.

Let the number be (10 x + y)
Then, 10 x + y = 3 * (x + y) (given)
Or, 10 x + y = 3 x + 3 y
Or, 10 x - 3 x = 3 y - y
Or, 7x = 2 y
Or, x = 2 y / 7 ( Eq. 1)
Also, 10 x + y + 45 = 10 y + x ( given)
Or, 10 x - x = 10 y - y - 45
Or, 9 x = 9 y - 45 ( Eq. 2)
Substituting the value of x from (Eq. 1) in (Eq. 2), we have:
9 * 2 y / 7 = 9 y - 45
Or, (9 y ) - (18 y / 7) = 45
Or, 63 y - 18 y = 315
Or, 45 y = 315
Or, y = 7
From (Eq. 1),
x = 2 * 7 / 7 = 2
So, the number is 10 x + y = (10 * 2) + 7 = (20 + 7) = 27
Answer
Check:
Sum of the digits = 2 + 7 = 9
9 * 3 = 27 ✓
Adding 45 to the number 27, we get 72. So, the digits get reversed.
Answer:
A. 35.69%
B. 62.77%
Step-by-step explanation:
In this case, what we must do is calculate the probability supported with the data in the table.
Part A.
What is the probability that a randomly selected student is a 7th grader?
Here the total is all the students that would be the sum of all the grades, which are 325 students.
the number of 7th graders is 116, so the probability is:
116/325 = 0.3569
that is, 35.69%
Part B: What percentage of the students interviewed play Video games?
The total number of students is the same 325 and of those 204 play video games, therefore:
204/325 = 0.6277
that is, 62.77%
