A normal distribution has a mean of 75 and a standard deviation of 10 use the standard normal table to find the probability that a randomly selected X value from the distribution is less than or equal to 50 A. -2.5
B. 0.0062
C. 0.9938
D. 2.5

0.006

Step-by-step explanation:

We are actually looking for the area under the standard normal curve to the left of 50.  The proper distribution function on my old TI calculator is normalcdf(:

normalcdf(-1000,50,75, 10),

which returns 0.006   (Answer B)

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
