You basically have to count how many days received the amount of mail listed in the left column. Then out of the total amount of mail received, you would compute the fraction of the days during which a given amount of mail was received.
For instance, on every day, at least 5 pieces of mail were counted, so there are 0 days on which 0-4 pieces of mail were received.
On the other hand, on days 5-7 (15, 18, 19), the amount of mail received fell within the 15-19 range. This means out of 7 days, 15-19 pieces of mail were received on 3 of those days. So the frequency with which this occurred was
.
So what you should get in the right column is
Answer:
x=9.6
Step-by-step explanation:
We are given the proportion:
We are asked to solve for x. Therefore, we must isolate x on one side of the proportion.
x is being divided by 24. The inverse of division is multiplication. Multiply both sides of the proportion by 24.
x is equal to 9.6 The complete proportion is
Answer:
sin(71°)
Step-by-step explanation:
Sine lags behind cosine by 90°
In other word, cos(∅) = sin(90° - ∅)
cos(19°) = sin(90° - 19°)
= sin(71°)
The no. of three types of tickets = x, y, z
The team has sold 3281 tickets over all.
x + y + z = 3281
It has sold 180 more $20 tickets than $10 tickets.
y = x + 180
The total sales are $63,600.
10x + 20y + 30z = $63,600
x + (180+x) + z = 3281
2x + z = 3281 - 180
2x + z = 3101
and
10x + 20(x+180) + 30z = $63,600
10x + 20x + 3600 + 30z = $63,600
30x + 30z = 63,600 - 3600
30x + 30z = 60,000
Simplify, divide equation by 30
x + z = 2000
Using these two equations for elimination:
2x + z = 3101
x + z = 2000
x ($10 tickets) = 3101 - 2000 = 1101 tickets
NOTE: I would like to point out the fact that a ticket costs $10,520, but in the next few sentences it claims to be $10. I will use $10 as a more relevant price, so if it is really $10,520, just change the numbers and you’ll get the answer. I’m sorry if my answer is incorrect!
Answer:
x>2
That is the answer do you want the work?
