A technician in an electronics lab is measuring the resistance of a critical electrical component. The component specification calls for minimum resistance of 97.5 . The technician makes twelve measurements of resistance with sample mean of 98.3  and sample deviation of 0.81 . The multi-meter used to perform the measurements has a stated accuracy of 200 m + 0.5% of the sample mean (one-sided confidence interval). Based on this information, determine:

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
