Answer:
Step-by-step explanation:
4ox-16=4[10x-4]this is because 4 is the common factor in both 40and 16
16x-24x-4±12=4[4x-6x-1±3]
-8x-8=8[-1-1]
Answer:
h(f(x)) = 2x - 11
Step-by-step explanation:
substitute for x in h (x), the values of f(x)
h(f(x))= 2(x-7)+3
=2x-14+3
=2x-11
Answer:
- 0.40666
Step-by-step explanation:
Given that:
Mean, m = 21.1
Standard deviation, s = 5.0
Score, x = 15
Zscore formula :
Zscore = (x - m) / s
Zscore = (15 - 21.1) / 15
Zscore = - 6.1 / 15
Zscore = - 0.40666
