I’m guessing 1/2 since he spent “half” her money
A function is linear if:
B. The function can be described by an equation of the form y = mx + b.
C. The function has a constant rate of change.
D. The function has a straight-line graph.
A function is said to be linear if it is a straight line graph and it can be represented by the equation:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
A linear function has a constant rate of change (either increasing or decreasing).

Answer:
Introducing Apples new, iBurrito
Step-by-step explanation:
Answer: Point of estimation = 32.60
Margin of error = 1.175.
95% confidence interval would be (81.95,84.45).
Step-by-step explanation:
Since we have given that
n = 49
Average = $32.60
Standard deviation = $5
We need to find:
1) Point of estimation for the mean of the population:
![\mu=\$32.60](https://tex.z-dn.net/?f=%5Cmu%3D%5C%2432.60)
2) At 90% level of confidence, z = 1.645
Margin of error would be
![z\dfrac{\sigma}{\sqrt{n}}\\\\=1.645\times \dfrac{5}{\sqrt{49}}\\\\=1.645\times \dfrac{5}{7}\\\\=1.175](https://tex.z-dn.net/?f=z%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%3D1.645%5Ctimes%20%5Cdfrac%7B5%7D%7B%5Csqrt%7B49%7D%7D%5C%5C%5C%5C%3D1.645%5Ctimes%20%5Cdfrac%7B5%7D%7B7%7D%5C%5C%5C%5C%3D1.175)
So, Margin of error = 1.175.
3) At 90% level of confidence, interval would be
![\bar{x}\pm 1.175\\\\=32.60\pm 1.175\\\\=(32.60-1.175,32.60+1.175)\\\\=(31.425,33.775)\\\\=(31.43,33.76)](https://tex.z-dn.net/?f=%5Cbar%7Bx%7D%5Cpm%201.175%5C%5C%5C%5C%3D32.60%5Cpm%201.175%5C%5C%5C%5C%3D%2832.60-1.175%2C32.60%2B1.175%29%5C%5C%5C%5C%3D%2831.425%2C33.775%29%5C%5C%5C%5C%3D%2831.43%2C33.76%29)
Hence, 90% confidence interval would be (31.43,33.76).
Answer:
I would the answer is x^6+1
Step-by-step explanation: First you add X^2 +x^4=X^6
than you add the 2/3 and the 1/3 which simpflies to 1
