The reputation of many businesses can be severely damaged due to a large number of defective items during shipment. suppose 300

batteries are randomly selected from a large shipment; each is tested and 9 defective batteries are found. at a 0.1 level of significance, does this provide evidence that the proportion of defective batteries is less than 5%? what is the p-value for the test.

We are given with
random samples = 300 batteries
defective samples = 9 batteries
level of significance = 0.1
Using the P-table values and using the given values, we see that the number of defective batteries are really less than 5%

How can you use a rate to compare the costs of two boxes of cereal that are different sizes?
Leya [2.2K]
If you are given a unit rate (ex: $0.59 per ounce) then you can multiple this by the weight of the cereal to find the cost of the entire box. Do this for both boxes, and then compare the costs.

Hope this helps. I'm not sure that I'm on the right path, but I can help you further if you provide more details.

Good luck!

A city’s population is increasing at a rate of 5% each year. Which type of model describes this situation?
Basile [38]

Answer:

Exponential

Step-by-step explanation:

Ir's exponential because linear would mean it is increasing by a specific number every year, in which this case does not. Quadratic would mean a vertex form would need to be used, and with the information given , that could not happen.

Write y= 3/5 x +4 in standard form using integers ?
BigorU [14]
Standard form for equations is ax + by = c. So all we have to do is transfer this equation into standard form. But, in standard form, there can also be no denominators, so our first step is to multiply each side of the equation by 5 to get rid of all denominators. The equation becomes 5y = 3x + 20. Now we need to get 20 on one side, which we can do by subtracting 3x from each side. The equation becomes -3x + 5y = 20, giving us our final answer of -3x + 5y = 20.
