Answer:
1.16 to 2.75
Step-by-step explanation:
The mean salary (millions of dollars) for shortstops was 1.95.

The population mean for all baseball players was 1.85

The population standard deviation was 1.61.

Formula of confidence interval :
to 
z at 95% confidence level = 1.96
Substitute the values in the formula
Confidence interval :
to 
Confidence interval : 1.16 to 2.75
Hence the 95 percent confidence interval for these data is 1.16 to 2.75
Answer:
3sqrt2
Step-by-step explanation:
If a side length is a, then a^2 + a^2 = 36
2a^2 = 36
a^2 = 18
a = 3sqrt2
Or, you can remember that in a square, if you cut it in half diagonally, you get a 45-45-90 triangle, so the sidenglth is diagonal/sqrt2
4th term would be
250 - (n-1)•13
250 - (4-1)•13
250 - 39

Cosθ = 15/17
Step-by-step explanation:
Sinθ = 8/17
We know that,
Sin^2 θ + cos^2 θ =1
64/289 + cos^2 θ =1
1 - 64/289 = cos^2 θ
225/289 = cos^2 θ
Cos θ = √225/289
Cos θ = 15/17
