Step-by-step explanation:
Total number of people, x=300
Number of people donated blood with type A, y

Number of people donated blood with type B, z

⇒Number of people with Type A blood donated more than those with Type B blood= y-z=84-60= 24
To get the answer of 7,280 all i can figure out is to multiply (X) 364 x 20 = 7,280 and that gives you the answer you show of 7,280.
Answer:
No
Step-by-step explanation:
In different scenarios, the data will be different. However, sometimes, it's impossible to draw a histogram with equal widths, so in order to maintain clarity and fairness, the area of the bars should actually be proportional to the frequency, which is usually the y-axis of the graph or height of the bars.
Hope this helps!
Solve the equation:
5 3
x – —— = – ——
7 7
5
Add —— to both sides, so you get x isolated at the left-hand side:
7
5 5 3 5
x – —— + —— = – —— + ——
7 7 7 7
3 5
x = – —— + ——
7 7
Now, add those fractions at the right-hand side of the equation:
– 3 + 5
x = —————
7
2
x = —— <——— this is the answer (first option: 2/7).
7
I hope this helps. =)
