Hello!
To calculate percent, it is number of positive cases / number of total cases. So first, we want to find the <u>number of positive cases.</u> You're looking for platinum and silver bands, so just add together the number of platinum and silver bands sold.
Platinum bands: 900
Silver bands: 900
Number of positive cases: 900 + 900 = 1,800
Now, look for the <u>number of total cases.</u> Here, just add together all the band types to get the number of rings bought in total.
Platinum: 900
Silver: 900
Gold: 700
Total number of cases: 900 + 900 + 700 = 2,500
Now, use the equation, and divide the two.
1,800 / 2,500 = .72 = 72%
Therefore, your answer is 72% of the rings sold had a platinum or silver band.
Hope this helps!
Answer:
Step-by-step explanation:
Move constant to right hand side and change it's sign
⇒
Add the numbers
⇒
<u>Let's </u><u>check</u><u>:</u>
When d = 15 , R.H.S = 15 - 7 = 8
And L.H.S = 8
Thus , R.H.S = L.H.S when d = 15.
Therefore d = 15 is the solution of the equation.
Hope I helped!

Answer:
It is the one you have selected. "The exact number of children on the playground each day."
Step-by-step explanation:
The stem and leaf plot shows each amount of children specifically. The histogram has the ages in groups. The stem and leaf plot is more specific and shows the inside information while the histogram only shows the number of children and frequency put in groups. I also took the quiz and got this right.
Hope this helps! Make sure to give me brainiest if somebody else answers.
