Answer:
5a+y+10 is your answer
Step-by-step explanation:
The prediction of the editor is not correct
Step-by-step explanation:
Step 1 :
Given,
Percentage of email that comes back undelivered = 3%
Number of email the editor sends out = 12181
Number of email predicted by the editor which is undelivered = 433
Step 2 :
To compute the actual number of emails undelivered we need to compute 3% of the emails that is actually sent.
= 3% of 12181 = 0.03 * 12181 = 365.43 which is 366 rounded to the closest integer.
Step 3:
Hence we can conclude that the prediction of the editor is not correct as only 366 undelivered notices are received back as against his prediction of 433 notices.
BEST estimate of this amount is
. Correct option A. 2 x 10^7 .
<u>Step-by-step explanation:</u>
Here we have , Hoover Dam spans the Colorado River on the Nevada-Arizona state line. For its construction, the federal government purchased 21,670,000 pounds of gates and valves. We need to find BEST estimate of this amount . Let's find out:
21,670,000 pounds
⇒ 21,670,000 pounds
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Now, Rounding of 2.167 we get 2 ,So
⇒ 
Hence , BEST estimate of this amount is
. Correct option A. 2 x 10^7 .
He used 12 gallons of white paint.
Because 20 divided by 5 = 4. Meaning that 4 gallons is one part.
4 x 5 = 20
4 x 3 = 12
