32 7/8 would be the answer. All you have to do is find a number multiplied by & that gets you close enough to 39
95% confidence interval would be (58.96, 69.04).
Step-by-step explanation:
Since we have given that
Number of dogs' weight = 20
Mean = 64 ounces
Standard deviation = 11.5 ounces
We need to find the 95% confidence interval.
So, z = 1.96
so, interval would be

Hence, 95% confidence interval would be (58.96, 69.04).

1.multiply the First terms. x⋅x=x2.
2.multiply the Outside terms. x⋅10=10x.
3.multiply the Inside terms. −10⋅x=−10x.
4.multiply the Last terms. −10⋅10=−100.
5.add all of the answers together. x2+10x−10x−100.
6.combine like terms. x2+10x−10x−100. =x2−100.

I hope this helps!!!
I'm too late but here ya go anyway :)
x = 180 - (31 + 40) is the answer.
