Answer with Step-by-step explanation:

We are given a data :

2, 2, 2, 2, 3, 3, 3, 4, 4, 5  

and its mean is 3

Mean absolute deviation means arithmetic mean of the absolute deviation about mean.

Deviation about mean is:

2-3,2-3,2-3,2-3,3-3,3-3,3-3,4-3,4-3,5-3

-1,-1,-1,-1,0,0,0,1,1,2

absolute deviation about mean is:

1,1,1,1,0,0,0,1,1,2

Arithmetic mean of the absolute deviation is:

1+1+1+1+0+0+0+1+1+2/10

= 8/10

= 0.8 cm

Answer:

2/9 is the correct option.

Step-by-step explanation:

As the spinner is numbered 2, 4 and 5

The general formula for probability :

P(A) = n(A) / n(S)

n(S) is the number of whole states occur in two spins which is 3 × 3 = 9

n(A) is the event that Rico will get a product of 20.

n(A) = 2   ∵ 4 × 5 and 5 × 4 will bring the product 20.

Therefor, the probability that Rico will get a product of 20 when Rico spins the spinner twice will be:

P(A) = n(A) / n(S)

       = 2/9

Therefore, 2/9 is the correct option.

T÷5/12= -3/10<br> Thank you if you help :)
skelet666 [1.2K]

Answer:

t = -1/8.

Step-by-step explanation:

t / 5/12 = -3/10          Invert the 5/12 and multiply:

12t / 5 = -3/10

Cross multiply:

12t * 10 = 5 * -3

120t = -15

t = -15/120 = -1/8.
