There is no table to look at.
Anyways, to solve for the amount they will spend you will have to do some conversions to switch yards and feet to inches. Additonally, there is also a rate missing which is the cost per inch.
So here is what you’ll have to do…
1. Solve for the slope of the equation
2. See if this linear equation has a y-intercept. It can be done by looking at the table to see where x=0 or by solving using y=mx+b where you substitite the slope for “m” and any coordinate that lies on the graph for “y” and “x” to then solve for “b” which is the y-int.
3. Then write out your equation.
4. Make the conversions
5. Solve for the cost by subtituting the units of measurement into the “x”.
Answer:
A= 74.47
Step-by-step explanation:
you add the 24.8 to the right side to get a by itself
To find this answer, we must first find the percentage of batteries that are defective. We can do this by dividing 3 by 500.
3 / 500 = 0.006
So our percentage of defective batteries is 0.6%.
Now, to find out how many defective batteries would be in a batch of 12000, we just need to multiply the constant (percentage of defective batteries) by the amount in the new batch.
12000 * 0.006 = 72
In a shipment of 12,000 batteries, 72 will be defective, so the correct answer choice would be B.
Hope that helped =)
Probability hit=40%=4/10
probability no hit=1-p (hit)=1-4/10=6/10
probability= p(hit)+p(hit)+p(hit)+p(hit)+p(hit)+p (no hit)+p (no hit)+p (no hit)
probability=4/10×4/10×4/10×4/10×4/10×6/10×6/10×6/10
=0.0022
( I think but I'm not 100% sure)
