Answer:

Step-by-step explanation:

You can write square root of four as √4

To find the square root multiply a number two times whose resultant product is 4.

2 is a number which is multiplied two times will give us 4

Therefore,

√4 = √2*2

2 makes a pair so that we will write it outside the root

√4 = √2*2

= 2

Thus the square root of 4 is 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

Is 10x-7 equivalent to (7x-5)-(3x-2)

ValentinkaMS [17]

no, because (7x-5) - (3x-2) = 4x-3

This would, however, be true if the equation was (7x-5) + (3x-2), but since the equation is subtracting instead of adding the equation isn't equivalent to 10x-7.
