Z-scores are expressed in terms of standard deviations from their means. <span>The standard score is simply the score, minus the mean score, divided by the standard deviation. It is calculated as follows:
z = X- mean / standard deviation
z = 2.7 - 2.4 / 1.5
z = 0.2</span>
C = - 1/2t + 6
The equation usually looks like this
C = k*t + n
If t = 0 than
C = n (from the table we see that C is 6 if t = 0) than
N = 6 too
For t = 2 and c = 5 we have the equation
5 = 2k + 6
2k = -1
K = -1/2
Answer:
y=5/3 x+b
Step-by-step explanation:
to be perpendicular, the product of two slopes should be -1
So, any linear function with the slope of 5/3 would be the answer.
Before the new kids the ratio of girls to boys is 15:12 because there are 15 girls and 12 boys now you can simplify by dividing 15 by 3 and 12 by 3 to get 5:4 as your simplified ratio. As far as after the new kids. Since there is 1 new girl you do 15+1 to get 16 and there are 3 new boys so you do 12+3 to get 15 now 16:15 is already in simplest form so your answer is:
Before: 15:12 simplified as 5:4
After 16:15
Hope this helps.
