what is the other number fore the first part?
Answer:
x = 4.5 or rounded 5
Step-by-step explanation:
Because they are equal you can make the equation:
x/2 = 18/8
this means that 8 divided by 2 equals (4)
what 18 divided by x is (4)
this means 4 times x = 18
4x = 18
/4 /4
x = 4.5 ft
Answer:
The correct value is t* = 1.690
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 36 - 1 = 35
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 35 degrees of freedom(y-axis) and a confidence level of
. So we have T = 1.69, which is the answer to this question.
