hram777 [196]

Answer:

The diversity index is 0.335 or 33.5%

Step-by-step explanation:

Probability index= probability that two people chosen at random are different ethnicity or races.

Let the probability of picking black = p(B) =0.15

probability of picking white= p(W)= 0.8

probability of picking Asian= p(A)=0.05

The probability of picking two people who are of different races or ethnicity can be gotten as:

Probability of picking: (White & Black) OR (White & Asian) OR (Black &Asian) OR (black &white) OR (Asian&white) OR (Asian& Black).

Using the notations given earlier, we can write the diversity index as:

Diversity index=p(W) x p(B)+ p(W) x p(A)+ p(B) x p(A) +p(B) x p(W)+ p(A) x p(W)+ p(A) x p(B)

Fixing the values for each term in the last expression gives:

Diversity index= 0.8x0.15 +0.8x0.05+ 0.15x0.05 +0.15x0.8+ 0.05x0.8+0.05x0.15

Diversity index= 0.12+0.04+0.0075+ 0.12+0.04+0.0075

Diversity index= 0.335 or 33.5%

Hence the diversity index is 0.335 or 33.5%

Which statement is correct? (Photo)

zavuch27 [327]

Answer:

First statement is correct.

Step-by-step explanation:

In the first statement,

in the left hand side, 10 has -3 as its power but in the right hand side +3 is the 10's power.

$2.06 \times 1.88 = 3.8728 \\\frac{7.69}{2.3} = 3.3435$

According to 10's power, left hand side < right hand side.

Hence, there is no need to check the other statements.

Oxana [17]

Answer:

Step-by-step explanation:

If cost price (CP) is greater than selling price (SP) , then the item is sold for loss.

Loss = CP - SP

Loss% = $\frac{loss}{CP}*100$

If SP is greater than Cp, then the item is sold for a profit.

Profit =SP -CP

Gain % = $\frac{gain}{CP}*100$

a) CP = $50 ; SP = $30 ; CP > SP, loss

Loss = 50 - 30 = $ 20

Loss % = $\frac{20}{50}*100=20*2$

= 40% loss

b) CP = £ 5000 ; SP = £6250 ; SP > CP , Profit

Profit = 6250 - 5000 = £ 1250

Profit % = $\frac{1250}{5000}*100=25$

25% Profit
