C. would be the correct device to use in trials.
But the actual probability is:
(1-1/4)^5
243/1024
(about 23.73% chance none of the five chose vanilla)
Answer:
C ≈ 22.1°
Step-by-step explanation:
The law of cosines formula is given. Solving it for C, we find ...
C = arccos((a^2 +b^2 -c^2)/(2ab))
where a and b are the sides adjacent to the angle.
Then we have ...
C = arccos((14^2 +19^2 -8^2)/(2·14·19)) = arccos(493/532)
C ≈ 22.1°

If you have a fair number of these to do, a spreadsheet is a useful tool. There are also triangle solver apps on the web or your local smart platform that will do this, too.
Answer:
8 number of cakes were sold.
Step-by-step explanation:
Out of 12 baked goods sold , let the number of cakes sold be x in number and pies sold were 12 − x in number. Total sell was $ 144 , 1 cake costs $ 14 and 1 pie costs $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96 or 6 x = 48 ∴ x = 8 Therefore, 8 cakes were sold [Ans]
For this case we can make the following rule of three:
2250 -----------> 100%
600 -------------> x
From here, we clear the value of x.
We have then:
Therefore, the decrease in percentage weight is:
Round to the nearest whole number:
x = 73%
Answer:
the percent decrease in the puppy's weight rounded to the nearest whole number is:
x = 73%
Answer: No, Mai needs to solve the problem.
Step-by-step explanation:
2x+2=x+1 - subtract 2 from both sides
2x=x-1 - subtract x from both sides
x= -1 - solution
