It’s still 6 because adding a constant does not change the standard deviation.
irina1246 [14]2 years ago

Answer:  I believe the standard deviation will remain the same, 6, choice A.

Step-by-step explanation:  Standard deviation is calkculated based on the difference of each point from the mean.  If 10 were added to each score, the mean would also increase by 10.  That would mean that the difference between the mean and each score would be exactly the same, leading to an identical standard deviation.  Sounds crazy, but that's what numbers do for a living.

At the movie theatre, child admission is $5.10 and adult admission is $9.00 .
sveticcg [70]

Answer:

5.10 X +9.00 Y = 831.60

We also know that for Wedneday we have two times tickets for adults compared to child so we have

Y =2x

And using this condition we have:

5.10 X + 18 X = 831.60

And solving for X we got:

X= \frac{831.60}{23.1}=36

So then the number of tickets sold for child are 36

Step-by-step explanation:

For this problem we can set upt the following notation

X = number of tickets for child

Y= number of tickets for adults

And we know that the total revenue  for Wednesday was 831.60. So then we can set up the following equation for the total revenue

5.10 X +9.00 Y = 831.60

We also know that for Wedneday we have two times tickets for adults compared to child so we have

Y =2x

And using this condition we have:

5.10 X + 18 X = 831.60

And solving for X we got:

X= \frac{831.60}{23.1}=36

So then the number of tickets sold for child are 36

The ratio of tom’s age to Mary’s is 3:4.If Tom is 15 how old is Mary
AnnZ [28]
Hey there!

Tom's age to Mary's is 3:4; an equivalent ratio is 15:x (x symbolizes Mary's age).

To solve for this, we need to divide our proportions. By that, I mean divide Tom's older age by his younger age. If we do so, we should get a scale factor that we can multiply Mary's younger age by.

15 / 3 = 5

This means that the scale factor of the ages is 5.

x / 4 = 5 (Solving for Mary's unknown age.)

To solve for x, multiply both sides by 4.

x/4 * 4 = x
5 * 4 = 20

x = 20

Mary's age is 20.

I hope this helps!
