Each family brought 11 chairs. You would just subtract 5 from 49 and divide it by 4 to get 11.
B is not a geometric sequence
Answer:
t-value = 2.441
Step-by-step explanation:
Let's assume that this is a one-tailed test to calculate the critical value, the process is this:
- Calculate alpha (α): α = 1 - (confidence level / 100)
, but we already have this α=0.01
- Find the critical probability (p*): p* = 1 - α/2 = 1-0.005=0.995
- Then, the critical value would be shown as a t statistic, but for this we need:
degrees of freedom (df)= n-1=35-1=34
- The critical t statistic (t*) or critical value is the t-value having degrees of freedom equal to 34 and a cumulative probability equal to 0.995.
From the attached table we can see:
t-value = 2.441
Answer: y = 3x + 4
Explanation: The slope is positive 3x and the y-intercept is +4 therefore the equation is y = 3x + 4 in y = mx + b form.
(mx is for slope, b is for y-intercept)
Hope this helps :)
