Step-by-step explanation:
We know that opposite sides of parallelogram are equal so
t + 10 = 3t
3t-t = 10
2t = 10
t = 10/ 2
t = 5
Therefore the value of the should be 5 so that it makes a parallelogram.

Answer:
the 90% confidence interval is ( 48.684 , 51.316 )
Step-by-step explanation:
Given that :
the sample size = 36
Sample Mean = 50
standard deviation = 4.80
The objective is to calculate a 90% confidence interval.
At 90% confidence interval ;
the level of significance = 1 - 0.9 = 0.1
The critical value for
= 1.645
The standard error S.E =
=
= 0.8
The Confidence interval level can be computed as:
For the lower limit :
=50 - 1.316
= 48.684
For the upper limit :
=50 + 1.316
= 51.316
Thus, the 90% confidence interval is ( 48.684 , 51.316 )
First, you multiply 0.7 and 60. 60 will be the minutes that equal one hour.
Finally, we can see that elephant can run up to 42 kilometers per hour. hope this helps!
