Mathematics
1 answer:
Verizon [17]3 years ago
4 0

Answer:

The answer is 0.

Step-by-step explanation:

Now, here we have to find the value of the expression:

b + (-b)

So here when we open up the brackets, we will get:

b + (-b)= b -b

So we can see that the term b is subtracted from itself and hence we get:

b -b=0

So the final value of the given expression:

b + (-b)= 0

and this is true for any real number b.

Suppose that you work for the child social services agency in your county. Your job is to investigate instances of possible chil
True [87]

Answer:

Null hypothesis: ∪ =  No possible child abuse or neglect

Alternative hypothesis: Uₐ = Possible child abuse or neglect

Step-by-step explanation:

Null hypothesis: ∪ =  No possible child abuse or neglect

Alternative hypothesis: Uₐ = Possible child abuse or neglect

A type I error occurs when you reject the null hypothesis when it is true. In this situation, a type I error occurs when you conclude on possible child neglect or abuse and place the child in protective custody

A type II error occurs when you accept the null hypothesis when it is false. In this instance, a type II error occurs when you conclude on no possible child abuse or neglect when there is and fail to remove the child from the home.

In this case, the type II error is the more serious error. Failure to remove the child when there is possible child abuse or neglect will lead to more detrimental effect. Although, the type I error is also serious, it is not so detrimental as the type II error.

suter [353]

Answer: 12$

Step-by-step explanation:

We need to round 79.45 to the nearest 10 dollars, which is 80.

We can then get 15% of it easily since its a whole number by adding 10% (8) and 5% (4) to get an estimate of around 12 dollars.
