laiz [17]

Answer:

0.595

Step-by-step explanation:

We are given that An archer hits centre of the target

We have to calculate the probability that she will hit the centre of the target on two consecutive shots.

P(A)=P(B)=0.70

P(B/A)=0.85

We know tha formula

$P(B/A)=\frac{P(A\cap B)}{P(A)}$

Substitute the value then we get

$P(A\cap B)=P(B/A)\cdot P(A)=0.85\times 0.70=0.595$

Hence, the probability that she will hit the centre of the target on two consecutive shots=0.595

Agata [3.3K]

Answer: The amount invested at 10% was $3200.

Step-by-step explanation:

Since we have given that

Principal amount = $7200

Rate of interest are 10% and 9%.

Total interest = $680

Let the amount invested on 10% be 'x'.

Let the amount invested on 9% be '7200-x'.

According to question, we get that

$\dfrac{x\times 10}{100}+\dfrac{(7200-x)\times 9}{100}=680\\\\10x+64800-9x=680\times 100\\\\x+64800=68000\\\\x=68000-64800\\\\x=\$3200$

Hence, the amount invested at 10% was $3200.
