Answer:
-6
Step-by-step explanation:
We are given x=- 3 , y= 6 and z= -4.
We are also given the expression:
-15 + (-x) +y
Substitute -3 in for x and 6 in for y.
-15 + (- -3) + 6
2 negative signs creates a positive sign
-15 + (+3) +6
-15 + 3+ 6
Add -15 and 3.
(-15+3) +6
-12 +6
Add -12 and 6.
-6
-15+(-x)+y evaluated at x= -3 and y=6 is equal to -6.
Answer:
The probability is 0.003907
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)/SD
mean = 506, SD = 115 , x = 200
z-score = (200-506)/115 = -2.66
The probability we want to calculate is;
P( x < -2.66)
we can use the standard normal distribution for this;
P(x < -2.66) is ) = 0.003907
