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
![\bar{x}\pm z\dfrac{\sigma}{\sqrt{n}}\\\\=64\pm 1.96\times \dfrac{11.5}{\sqrt{20}}\\\\=64\pm 5.04\\\\=(64-5.04,64+5.04)\\\\=(58.96,69.04)](https://tex.z-dn.net/?f=%5Cbar%7Bx%7D%5Cpm%20z%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%3D64%5Cpm%201.96%5Ctimes%20%5Cdfrac%7B11.5%7D%7B%5Csqrt%7B20%7D%7D%5C%5C%5C%5C%3D64%5Cpm%205.04%5C%5C%5C%5C%3D%2864-5.04%2C64%2B5.04%29%5C%5C%5C%5C%3D%2858.96%2C69.04%29)
Hence, 95% confidence interval would be (58.96, 69.04).
Answer:
Y = 3/4x - 2
Step-by-step explanation:
Slope = (1 - - 5)/(4 - - 4 =6/8 = 3/4
b = -5 - (3/4)(-4)
b = -5 + 3 = -2
y = 3/4x - 2
You should change the y by the number given
P=6-2*-5
P=16
Any number raised to the power of 0 is 1.
Therefore, 15^0 = 1
Answer is UY Because they both connect her causing an intersection
