Answer:
a
Step-by-step explanation:
The
temperature which has best degree of precision would actually be the
temperature reading which has similar decimal place with the error. So the best
answer would have 1 decimal and from the choices given above, this would be:
16.0°C

Let us denote the smaller even integer by

.
Then, the next even integer must be

.
To verify, set

as any even number, say

.
Then, the next even integer must be 2 more than this number, i.e.

.
The sum of these two consecutive even integers can be expressed as:

We are told that this sum divided by four is 189.5, i.e.

Multiplying both sides by 4 will reverse the division:

Subtracting 2 from each side will reverse the addition:

Dividing both sides by 2 will reverse the multiplication:

Therefore, the two consecutive integers must be
378 and
380.
Check this:
Answer:
m - 10
Step-by-step explanation:
7 plus = 7 +
The sum of m and -17 = m + (-17)
7 + (m + -17)
We can get rid of the parentheses
7 + m + -17
Combine like terms
7 + -17 = -10
m + -10
Get rid of the addition sign
m - 10
Answer: 
Step-by-step explanation:
Since we have given that
A very large study showed that aspirin reduced the rate of heart attacks by 44%.
we claim that they have a drug that will be more effective than aspirin.
so, our hypothesis would be

So, it will be one tail test.
Hence,
