Aset of data has a normal distribution with a mean of 50 and a standard deviation of 6. what percent of the data should be less than 50?

The percent of the data should be less than 50 is 50%

Step-by-step explanation:

we are given

mean=50

standard deviation is 6

and

x=50

so, we can use formula

now, we can plug values

Since, the data should be less than 50

so,

now, we can use normal distribution table

we get

So,

The percent of the data should be less than 50 is 50%

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
