Answer: 15
Step-by-step explanation:
Average is sum of scores/ number of scores, from the question, average is given as 15.
Let the missing score be x
Equation for the questionis represented as: 12 + 18 + x /3 = 15
30 + x /3 = 15
Cross multiply
30 + x = 15×3
30 + x = 45
Subtract 30 from both sides
30 + x -30 = 45 -30
x = 15.
Check:
12 + 18 + 15/3 = 15
45/3 = 15
I hope this is clear, please mark as brainliest answer
Answer: C
Step-by-step explanation:
We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.
So, basically, if a graph is a function, it is a relation as well.
Let’s check if this is a function.
We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function
In our case, it passes the vertical line test.
Therefore, it is both a function and a relation, which corresponds to letter C.
Hope this helps! :)
Answer:
4(c)- 3
Step-by-step explanation:
i chose this answer because if there are 4 tickets and each one is c(?) which is an unknown amount in this equation. First youd have to multiply 4 by c to find the total amount and since they are giving a discount of $3 you subtract $3 from the total.
Answer:
Total cost= $760
Step-by-step explanation:
Giving the following information:
Number of students= 347
Each bus holds 44 students.
Bus cost= $95
<u>First, we need to determine the number of buses needed:</u>
Number of buses= total students / student per bus
Number of buses= 347 / 44
Number of buses= 7.88 = 8 buses
<u>Now, the total cost:</u>
Total cost= 8*95
Total cost= $760
Answer:
B
Step-by-step explanation:
all the equations start with y = 2x so all the graphs will paralel but because every single equation has different constant number, it will result different y-interceps.
