Answer:
The answer is E. Impossible to determine
Step-by-step explanation:
Normally, you would find the Confidence interval of a normal sample by using
X(-+) Z* Sigma/n
Where x is the mean, sigma the standard deviation n the size of the sample and z the value determined by your confidence interval size of 95%
.However, this approximation of a confidence interval may only be used for a sample if the number of observations is at least 30 or above. When we have less observations than 30 we must use the standard deviation of the populations. But we only have a sample standard deviation so its not adequate or possible to determine CI the true mean of the population with such a small sample size.
Answer:
C
Step-by-step explanation:
The diagram goes up in increments of 2/8 5 times, which C represents.
Answer: 150c + 400t ≥ 4900
Step-by-step explanation:
Let the number of chairs sold = c
Let the number of tables sold = t
Price for each chair = $150
Price for each table = $400
The inequality that could represent the number of tables and chairs sold will be:
(150 × c) + (400 × t) ≥ 4900
150c + 400t ≥ 4900
10 cm because there are 10 mm in 1 cm so 38.5 mm = 3 cm and that is not larger than 10 cm
Answer:
<em>tanB</em><em>=</em>p/b
tanB=3/4
B=tan-¹(3/4)=17.89=18° is your answer.
