Answer:

3.5 and 3½

Step-by-step explanation:

Half of 7 is positive 3.5 aka 3½. It can't be -7/2 or -3.5 because they result in a negative number. It also can't be 7.2 because that's too big of a number.

A digital scale reports a 10kg weight as weighing 8.975kg. which of the following is true?
lukranit [14]
That question is accompanied by these answer choices:

<span>A. The scale is accurate but not precise.
B. The scale is precise but not accurate.
C. The scale is neither precise nor accurate.
D. The scale is both accurate and precise.

Then you need to distinguish between accuracy and precision.

Accuracy refers to the closeness of the measure to the real value, while precision, in this case, refers to the level of significant figures that the sacle report.

The fact that the scale reports the number with 4 significant figures means that it is very precise, but the fact that the result is not so close to the real value as the number of significan figures pretend to be, means that the scale is not accurate.

So, the answer is that the scale is precise but not accurate (the option B).

You roll a six-sided die twice. What is the probability of rolling an even number and then an odd number?
nlexa [21]

Answer:

C) 1/4

Step-by-step explanation:

Because you have six-sided dice there are 3 odd numbers and 3 even numbers. That means you have a 1/2 for getting either a odd or even number. So we would add 1/2 + 1/2 because you are rolling two times and both have a 1/2 of getting either a odd or even number. 1/2+1/2 = 1./4 which would be your answer.

Hope this helped! Have a good day/night and good luck! Stay safe!!
