Answer:
h(-4) =101
Step-by-step explanation:
H(x) = 6x ^2 +5
We have to find when h=4, putting it into function
h(-4) = 6(-4) ^2 +5
h(-4) = 6(16) +5
h(-4) = 96 +5
h(-4) =101
Answer:
the answer is 65

Answer:
Step-by-step explanation:
Given that in order to efficiently bid on a contract, a contractor wants to be 95% confident that his error is less than two hours in estimating the average time it takes to install tile flooring.
Std deviation =4.5 errors
95% confidence interval = Mean±1.96*std dev
Hence we have

Sample size should be 20.
