2 answers:
Total number of websites = 6The approximate probability that she checked a social website first, then a school-related website = 4/6 x 2/5 = 0.267
Answer:
Option b
Step-by-step explanation:
Given that there are 6 websites out of which four are social and two school related.
Total number of websites the student checked =2
Probability that she checked social website first= no of social websites/no of total websites
= 4/6= 0.667
Now available are 5 websites out of which 3 social and 2 school related
Prob for second school related =2/5 =0.40
Hence required probability = 0.667(0.40)
= 0.2668
=0.267

Answer:
output = 23
Step-by-step explanation:
x = -4
f(x) = 3ǀ2x - 1ǀ + x
f(x) = 3ǀ2(-4) - 1ǀ + (-4)
f(x) = 3ǀ2(-4) - 1ǀ - 4
f(x) = 3ǀ-8 - 1ǀ - 4
f(x) = 3ǀ-9ǀ - 4
f(x) = 3(9) - 4
f(x) = 3(9) - 4
f(x) = 27 - 4
f(x) = 23
