What is the standard deviation of this data 10,12,8,2

Mathematics
1 answer:
Mazyrski [523]4 years ago
6 0

Answer:

Step-by-step explanation:

First you need to find the mean of the set so 10+12+8+2=32/4=8

Mean=8

Then subtract the mean of each number and square the result

10-8=2^2=4

12-8=4^2=16

8-8=0^2=0

2-8=-6^2=36

new data set: 0,4,16,36

Next find the mean of this set of data

0+4+16+36=56/4=14 now take the square root of that mean

sqrt14=3.74

Hope this helps

HELLLPPPPPPP .... The probabilities of a test are represented by I for infected; U, uninfected; D, infection detected; and N, no
Dominik [7]

Answer:

P(I⋂D)

Step-by-step explanation:

The symbolic way to represent the probability of a true positive is P(I⋂D).

We know that I stands for Infected, U stands for Uninfected, D for Infection detected, N for infection no detected.

Then, a true positive will be given by the intersection of Infected and Infection Detected.

The figure below is made of 2 rectangular prisms.<br><br>What is the volume of this figure?
mixer [17]

Answer:

6536 cubic in

Step-by-step explanation:

1. Split both the prisms apart- In doing so, you can simplify the problem.

2. Put in the #'s for the formula which in this case is V=L*W*H, we will start with the formula for the front one, V=7*8*1 or V=7*8

3. answer for the front is 56 cubic in, now we solve for the other half.

4. V=9*1*90 or V=9*90 which is 6480 cubic in.

5. add 6480 and 56 and your answer is 6536 cubic in as your answer.

Hope this helped ;D
