Answer: 214.8
Step-by-step explanation:
First move the decimal to the right, in this case 8.95 = 895., then multiply the 24 by 895. to get 21480., you then move the decimal to the left and you get 214.80 or 214.8.
The answer is B, because A and C are automatically eliminated because they are subtracting, and the equation that represents the situation is an addition inequality. B is correct because the two parenthesis numbers represents the students attending the fair paying $0.50, and there are 200 students. The 2.25a represents an amount of adults, each paying $2.25.
Answer: B
Answer:
a) 2.0702
b) 2.07
Step-by-step explanation:
Given:
Sample, n = 840
standard deviation, σ = 60
a) The standard deviation of the sampling distribution, will be:
= 2.0702
Standard deviation of the sampling distribution is 2.0702
b) According to the 68 part of the 68-95-99.7 rule, 68% of all values of x fall within 1 standard deviation on either side of the unknown mean μ.
Therefore, missing number will be:
![1 * [\frac{\sigma}{\sqrt{n}}]](https://tex.z-dn.net/?f=%201%20%2A%20%5B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5D%20)
= 1 * 2.0702
= 2.0702 ≈ 2.07
