Given:
The equation is
![\dfrac{3}{2}+b=\dfrac{7}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B2%7D%2Bb%3D%5Cdfrac%7B7%7D%7B4%7D)
To find:
The value of b.
Solution:
We have,
![\dfrac{3}{2}+b=\dfrac{7}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B2%7D%2Bb%3D%5Cdfrac%7B7%7D%7B4%7D)
Subtracting both sides by
, we get
![b=\dfrac{7}{4}-\dfrac{3}{2}](https://tex.z-dn.net/?f=b%3D%5Cdfrac%7B7%7D%7B4%7D-%5Cdfrac%7B3%7D%7B2%7D)
![b=\dfrac{7-2(3)}{4}](https://tex.z-dn.net/?f=b%3D%5Cdfrac%7B7-2%283%29%7D%7B4%7D)
![b=\dfrac{7-6}{4}](https://tex.z-dn.net/?f=b%3D%5Cdfrac%7B7-6%7D%7B4%7D)
![b=\dfrac{1}{4}](https://tex.z-dn.net/?f=b%3D%5Cdfrac%7B1%7D%7B4%7D)
Therefore, the value of b is
.
Answer: The slope is -8/3
Step-by-step explanation: Use the slope formula y2-y1/x2-x1
so -9-7/2-(-4) = -16/6 which can be divided by 2 to get -8/3
I’m assuming you meant in each shelf there is 14 movies, and there is 4 shelves, so you would multiply 14 x 4 which would be 56 movies
Answer:
![H_A: P_{\text{Internet}}-P_{\text{Store}} > 0.10](https://tex.z-dn.net/?f=H_A%3A%20P_%7B%5Ctext%7BInternet%7D%7D-P_%7B%5Ctext%7BStore%7D%7D%20%3E%200.10)
Step-by-step explanation:
We are given the following in the question:
Let
be the proportion of the internet sales and
be the proportion of the store sale.
Hypothesis:
We have to conduct a hypothesis to check that the Internet sales are more than 10 percent higher than store sales.
Thus, we can design the null and alternative hypothesis as:
![H_{0}: P_{\text{Internet}}-P_{\text{Store}}\leq 0.10\\H_A: P_{\text{Internet}}-P_{\text{Store}} > 0.10](https://tex.z-dn.net/?f=H_%7B0%7D%3A%20P_%7B%5Ctext%7BInternet%7D%7D-P_%7B%5Ctext%7BStore%7D%7D%5Cleq%200.10%5C%5CH_A%3A%20P_%7B%5Ctext%7BInternet%7D%7D-P_%7B%5Ctext%7BStore%7D%7D%20%3E%200.10)
Alternate Hypothesis:
The alternate hypothesis states that the proportion of the internet sales is greater than the proportion of store sales by 10 percent.
