I’m sorry I don’t know but Microsoft math app is a rlly good app for these problems
I think that the answer is -262144
Answer:
Option c
Step-by-step explanation:
In Statistics, both t and z tests are used for testing of hypothesis.
Whenever we have sample sizes >30 and when we know population std deviation sigma, we use Z test.
i.e. if sigma is known, we check whether sample size >30 then we use z test
Otherwise if population std deviation is not known, we use t test.
Even if population std deviation is known, if n <30 we use t test. Both use the same formula for std error.
Hence the correct option is option c.
Hey there! I'm happy to help!
We want to find to find the length of the wire that will go around the friends field. The distance around something is called the perimeter. To find this, we will take our two sides with the length of 219 and two sides with the width of 7525 and then add them.
2(219)+2(7525)=15488
Therefore, we will need a wire with a length of 15488.
I hope that this helps! Have a wonderful day!
