Answer:

37 Dimes, 29 Nickels

Step-by-step explanation:

x= dimes

66-x = nickels

.1 (x) = dimes

.05 (66-x) = nickels

Solve

3.3 + 0.5x = 5.15

Solve again then you come out with

x= 37

66 - 37 = 29

-5 1/2 -4 1/4 - 6 3/4

BlackZzzverrR [31]

For this case we have an expression of mixed numbers:

$5 \frac {1} {2} = \frac {2 * 5 + 1} {2} = \frac {11} {2}\\4 \frac {1} {4} = \frac {4 * 4 + 1} {4} = \frac {17} {4}\\6 \frac {3} {4} = \frac {4 * 6 + 3} {4} = \frac {27} {4}$

Rewriting the expression we have:

$- \frac {11} {2} - \frac {17} {4} -\frac {27} {4} =$

Remember that equal signs are added and the same sign is placed.

$- \frac {11} {2} - \frac {44} {4} =\\- \frac {11} {2} - \frac {22} {2} =\\- \frac {33} {2}$

Answer:

$- \frac {33} {2}\\-(15 \frac {3} {2})$

An archer hits the center of the target (the bullseye) 70 percent of the time. However, she is a streak shooter, and if she hits

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
