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.

Nethan made 8 rose bouquets and 6 daffodil bouquets. Nethan only has enough flowers to make at most 20 rose or daffodil bouquets
Solnce55 [7]

Answer:

Nethan made 8 rose bouquets and 6 daffodil bouquets.

Nethan only has enough flowers to make at most 20 rose or daffodil bouquets total.

Let x represents the number of more rose bouquets.

Let y represents the number of more daffodil bouquets.

The maximum bouquets that can be made = 20

And the number of bouquets made are = 14

So, additional bouquets are = 20-14=6

In equation form we can show like :

x +y= 6

or y=6 -x

or x=6- y

Putting values of x as 0,2,4 and 6 we get:

When x = 0 then y = 6  

When x = 2 then y = 4

When x = 4 then y = 2

When x = 6 then y = 0

You can see the graph attached.

Researchers at the Centers for Disease Control and Prevention have been studying the decay pattern of a new virus with a decay r
Andrei [34K]

Answer:

They will find 69 viruses in 8 hours.

Step-by-step explanation:

The number of viruses after t hours is given by the following equation:

V(t) = V(0)(1-r)^{t}

In which V(0) is the initial number of viruses and r is the decay rate, as a decimal.

They start with 500 viruses

This means that V(0) = 500

Decay rate of 22% per hour.

This means that r = 0.22

So

V(t) = V(0)(1-r)^{t}

V(t) = 500(1-0.22)^{t}

V(t) = 500(0.78)^{t}

How many viruses will they find in 8 hours?

This is V(8).

V(t) = 500(0.78)^{t}

V(8) = 500(0.78)^{8}

V(8) = 68.51

Rounding to the nearest whole number

They will find 69 viruses in 8 hours.

River collects old coins. He has four
vlabodo [156]

9514 1404 393

Answer:

  c) 5n +25q = 365

     2q -4 = n

Step-by-step explanation:

The number of nickels (n) is 4 less than twice the number of quarters (q), so one of the equations is ...

  2q -4 = n

The face value is 365 cents, so another equation is ...

  5n +25q = 365

These equations seem to match choice C.
