The circumference of this problem would be 25.13. I hope this helps you.
Disagree because 24 divided by 1/2=48
Working out
24 divided by 1/2
To divide by a fraction, multiply by the reciprocal of that fraction
24 x 2
Multiply
48
Solution
48
Given:
95% confidence level
sample size (n) = 91
Find: the lower and upper critical values in a chi-square distribution
Solution:
1. Calculate the degrees of freedom. Since the number of rows and columns is not specified in the question, we will subtract 1 from the sample size.
![91-1=90](https://tex.z-dn.net/?f=91-1%3D90)
Our degrees of freedom (df) = 90.
2. Since this is two-tailed, subtract 0.95 from 1, then divide the result by 2.
![\frac{1-0.95}{2}=\frac{0.05}{2}=0.025](https://tex.z-dn.net/?f=%5Cfrac%7B1-0.95%7D%7B2%7D%3D%5Cfrac%7B0.05%7D%7B2%7D%3D0.025)
3. Let's now look at the chi-square distribution table and look for df = 90 with a probability of 0.025 on both the left and right tails.
Based on the table, the lower critical value is 65.647 while the upper critical value is 118.136.
Hence, the answer is Option B.
Answer:
6.
Step-by-step explanation:
x/7 - 3/8 = 27/56
Multiply through by 56 , as 7 * 8 = 56 we have:
8x - 3*7 = 27
8x = 27 + 21 = 48
x = 6.
