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

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

Which are the like terms in 2y3 – 4y2 + y + y3?

stealth61 [152]

C is the correct answer. A, B, and C have terms with different powers of y, and as a result, these terms are not like. C, however, has only multiples of y cubed, so it is a set of like terms.

Determine the number of solutions that exist to the equation. 8(j-4)=2(4j-16)

lukranit [14]

<span>8(j-4)=2(4j-16)
8j - 32 = 8j - 32

Since both sides are equal, there are is an infinite number of solutions.
