Answer:
The ratio of the number of bulbs tested to defective bulbs is always 14 to 1.
<u><em>What is the unitary method?</em></u>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We generally expect industrial processes to produce defects at about the same rate, the proportion of the defective product is generally considered to be a remain constant.
Here, the proportion of defective bulbs is:
1/14 = 2/28 = 6/84
So, it will be 24/336.
The ratio of the number of bulbs tested to defective bulbs is expected to remain constant at about 14.

Answer:
16 and 9
Step-by-step explanation:
2+14=16 7+2=9
First, we have to get the fractions to common denominators.
4/5 = 16/20
1/4 = 5/20
5 5/20 - 3 16/20 = 1 9/20
She put 1 9/20 extra cups in.
50mph
Step-by-step explanation:
The image of the motion of Paul's derive is attached already.
From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.
What is average speed?
Average speed is the rate of change of total distance covered with time taken .
Average speed = 
To find the total distance covered;
Distance at time 1 = 75miles
Distance at time 4 = 225miles
Distance covered between 1 - 4 = 225 - 75 = 150miles
Time taken for the journey = 4 - 1 = 3hrs
Input the values in the equation;
Average speed = 
= 50mph
