Precision is more like consistency. Take a rifle range for example. Sure, all the shots may be off centered, but if they're tightly grouped together, it shows that the shooter had precision in their shooting. Accuracy is how close to spot on the attempts or shots generally are. They would end up more towards the center, but a little more spread out.

Is 1 prime or composite

<span>trick question
One is neither a prime nor a composite number. A prime number is divisible by its self and one. One has only one positive divisor.

These are the numbers whose reciprocals are also whole numbers.</span>

Which equation results from taking the square root of both sides of (x + 9)2 = 25?

Alex_Xolod [135]

Answer:

√2.37+ 3 √9 = √5. 3 is the last one

x+9 =+25

Step-by-step explanation:

(x+9)2= 25 This means x= 3.5 and the square root of x = √3.5 = 1.87 square root of 9 x 2 = √18 =4.24

We can also see 18+7 =25

√5.65 √5
