Answer:
D
Step-by-step explanation:
You would do D because the other options aren't that random. Randomly choosing employees <em>is</em> a random sample and will give you a valid answer.
Answer: 0.75
Step-by-step explanation:
A survey of 364 children aged 19-36 months found that 91 liked to eat potato chips.
Total children surveyed= 364
Those that like to eat potato chips= 91
Those that don't like to eat potato chips= 364 - 91 = 273
Probability that the child chosen doesn't like to eat potato chips will be children that don't like to eat potato chips divided by total number of children surveyed.
= 273/364
= 0.75
Answer:
a=11, b=53
Step-by-step explanation:
y=ax+b
x=1, y=64 -> 64=a+b
x=2, y=75 -> 75=2a+b
75-64=a, a=11, b=53
All the other points obey this rule.
Answer:
C. f(x) = x - 7 all over 4
Step-by-step explanation:
NB: Let f(x) = y
Exchange X and Y
Make y the subject
f(x) = 4x + 7
y = 4x + 7
x = 4y + 7
x - 7 = 4y
x - 7 all over 4 = 4 ÷ 4
y = x - 7 all over 4
The answer is 19.5
You add all the numbers to get 273 and divide by the amount of dots which is 14 to get 19.5
