Answer: 10 / 11 × 99

Step-by-step explanation:

The first one is; 16/15 × 99 = 1584/15 = 105.6

Its greater than 99

The second one is; 12/7 × 99 = 1188/7 = 169.71

The value is greater than 99

The fourth one is; 20/20 × 99 = 1980/20 = 99

The value is equal 99

The third one is; 10/11 × 99 = 990/11 =90

The value is less than 99

Therefore the product of 10/11 ×99 is less than 99

The probability model below describes the number of repair calls that an appliance repair shop may receive during an hour. Compl
defon

Answer:

a) So, she can expect a 2.4 calls per hour.

b) So, the standard deviation is 0.8.

Step-by-step explanation:

We know that probability model below describes the number of repair calls that an appliance repair shop may receive during an hour.

Repair Calls 1 2 3 4  

Probability 0.1 0.5 0.3 0.1

a) We calculate how many calls should the shop expect per hour.

We get:

E(X)=1\cdot0.1+2\cdot0.5+3\cdot0.3+4\cdot0.1\\\\E(X)=0.1+1+0.9+0.4\\\\E(X)=2.4

So, she can expect a 2.4 calls per hour.

b) We calculate the standard deviation:

\sigma=\sqrt{(1-2.4)^2\cdot 0.1+(2-2.4)^2\cdot 0.5+(3-2.4)^2\cdot 0.3+(4-2.4)^2\cdot 0.1}\\\\\sigma=\sqrt{0.196+0.08+0.108+0.256}\\\\\sigma=\sqrt{0.64}\\\\\sigma=0.8

So, the standard deviation is 0.8.
