Answer:
2.6549
Step-by-step explanation:
Since the sample size n=65, the degrees of freedom is n-1=65-1=64
The critical value=
Using the t-table and selecting df=64 and 
since it’s a 2 tail the corresponding t-score is 2.6549
Therefore, the critical value is 2.6549
Answer:
0.85 kilograms
Step-by-step explanation:
The nearest hundredth can be defined as a place value used when rounding up numbers after the decimal.
The nearest hundredth can also mean rounding up to 2 decimal places.
We are asked to round up 0.845 to the nearest hundredth
The nearest hundredth is the second number after the decimal = 4
The third number after the decimal = 5, hence we add 1 to 4 , making it 5.
Hence:
0.845 kilograms to the nearest hundredth = 0.85 kilograms
Answer:
<h2>0.035</h2>
Step-by-step explanation:
This problem is on probabilty since there are a number of entries to be selected from which are 85 entries, the chances of winning one of the prices if selected is
the number of entries you have/ total number of entries
given that the total entry is 85
and that you have one entry
Since there are three gift baskets you have three chances to win one.
hence there will be a total of three draws, and after each draw, there won't be a replacement of the previous winner (as the winners are three distinct persons).
Hence the probability of winning a draw for the gift basket is
=1st draw+2nd draw+3rd draw
= 1/85+1/84+1/83
= 0.0117+0.0119+0.012
= 0.035
Answer:
The slope-intercept form, or y=mx+b, would be y=4x-16.
Step-by-step explanation:
if you use the data given, it would be 4=4(-5)+b.
4=-20+b
Then you would subtract '-20' from both sides.
-16=b.
Now, if you plug in the numbers without the (x,y). It would be,
y=4x-16.
