Answer:

x = 240 days

Step-by-step explanation:

If we know that Brad completes 1/6 of his project every 40 days, that means it will take him 40 x 6 days to complete this project. If where to write this down as an equation we get the following.

Let "x" be the total number of days Brad needs to finish his project, then....

\frac{1}{6} x = 40 days

(\frac{1}{6} x)(6) = (40)(6)days

x = 240 days

In N=25 games last season, the college basketball team averaged u=76 points with a standard deviation of o=6. In their final gam
astraxan [27]

Answer:

b) far above average

Step-by-step explanation:

Normal Distribution

mean      μ₀  = 76

Standard Deviation   σ = 6

Values in Normal Distribution spread according to:

μ₀  +   σ    =  67.3 %

μ₀  +  2*σ =   95.5 %

μ₀  +  3*σ =   99.7 %

Is relevant to explain that these values spread simmetrically, having as symmetry axis the mean (That is: when we see  μ₀  +  2*σ,  that means that from  μ₀, we will find half of values under the mean and the other half above)

To examine the value 89, scored in the last game we will look for our paticular case values obtained from previuos conditions

That implies:

μ₀  +   σ    = 76 ± 0,5σ     =  76  ± 3      upper limit 79

μ₀  + 2σ    = 76  ±    σ       = 76  ± 6      upper lmit   82

μ₀  + 3σ    = 76  ±   1.5 σ   = 76 ± 9      upper limit  85

We should expect most of the values between the above intervals, the value " 89 " is bigger than 85, the point limit of the 99.7 % of all values, so we should conclude that 89 is far above average ( μ₀ )

License plates are made using 2 letters followed by 4 single digits. If any letter can be only used once but the digits can be r
mash [69]

Answer:

6,500,000

Step-by-step explanation:

Here, we first need to find all the possible selections for the code.

Then, we need to find the number of options for each one of these selections.

We have, 2 letters followed by 4 single digits.

There are 26 letters

There are 10 single digits.

For the first letter, we have 26 options.

For the second letter, we have 25 options (because one is already taken, and we can repeat that)

And for each one of the numbers, we have 10 options (we can repeat the numbers)

The total number of options for the code, is equal to the product of all the numbers of options for each selection, then the total number of possible plate numbers is:

C = 26*25*10*10*10*10 = 6,500,000
