Answer:
6*2=?
Explantion:
This is how it would look like, i didnt do a multiplcation sign because it would be 6 times 2. You are asking 6 times its self two times. Hope it helps!
So 6 x 6 or 6*2
NOT 6 X 2
You would multiply each side by 16 to get c=128.
Answer:
a) (490,510)
b) (480,520)
c) (470,530)
Step-by-step explanation:
Mean, μ = 500
Standard Deviation, σ = 10
Empirical Rule:
- According to Empirical rule almost all data lies within three standard deviation of mean for a normal distribution.
- About 68% of data lies within one standard deviation of the mean.
- About 95% of data lies within two standard deviation of mean.
- About 99.7% of data lies within three standard deviation of mean.
a) 68% of the observations
About 68% of data lies within 490 and 510.
b) 95% of the observations
About 95% of data lies within 480 and 520.
c) All the observations
All of the observations lie between 470 and 530.
Answer:
I am pretty sure the answer is C.
Step-by-step explanation:
Since the total amount of quarters and dimes Javier has is 24, we can use the variables d (representing the dimes) and q (representing the quarters) and come up with <u><em>d + q = 24 </em></u>for the first part.
for the second part, we know that every dime is worth 10 cents, or, .10 and every quarter is worth 25 cents , or .25 so for the second part, we can come up with the equation<u><em> .10d + .25q = $3.75 .</em></u>
