Answer:
-9
Step-by-step explanation:
few words about function notation. If f is a function, then f(x) is the
value of the function at x, usually denoted by some sort of rule for finding
the value of the function given that you know the value of x. f(a) would be
the value of the function at a, and f(4) would be the value of the function at,
=4
In this case the value of the function f at x, or f(x) is given by the rule:
f(x) = -x - 5 You want to know f(4), which is the value of the function at
4, so f(4) = -(4) - 5 = -9

what is -0.75 - 0.4 simplified
Answer:
= -0.75-0.4
= -1.15
Step By Step
The simplified result of -0.75 - 0.4 is -1.15.
To simplify the expression -0.75 - 0.4
Step 1: Start by subtracting the decimals without considering the signs: 0.75 - 0.4 = 0.35.
Step 2: Now, remember that the original expression had a negative sign in front of it, so the final answer needs to be negative. Since we already calculated a positive value (0.35), we'll make it negative by adding the negative sign: -0.35.
Step 3: Finally, we need to subtract the whole number parts. -0 (whole number part of -0.75) - 0 (whole number part of -0.35) = 0.
Putting it all together, we have -0 - 0.35 = -0.35.
But remember, the original expression had a negative sign, so the final result is -(-0.35), which simplifies to -0.35.
In mathematical terms, -0.75 - 0.4 = -0 - (0.75 - 0.4) = -0 - 0.35 = -0.35.
So, the simplified answer is -0.35, which can also be written as -1.15 (since -0.35 = -1.00 + 0.15).
In summary, when you subtract -0.4 from -0.75, you get -0.35 or -1.15, depending on how you choose to express it.

Suppose we know that a confidence interval is (27,35), with a margin of error of 4. Find the sample mean (x¯).
May u explain it alittle more im just confused
The formula for the sample mean, the margin of error, and the confidence interval.
Sample mean + margin of error = High-end confidence interval
Sample mean - margin of error = Low-end confidence interval
The sample mean is 31.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
Confidence interval = (27,35).
The margin of error = 4.
The formula for the sample mean, the margin of error, and the confidence interval.
Sample mean + margin of error = High-end confidence interval
Sample mean - margin of error = Low-end confidence interval
Now,
The sample mean = x
x + 4 = 35 ____(1)
x - 4 = 27 _____(2)
From (1) we get,
x = 35 - 4 = 31
From (2) we get,
x = 27 + 4
x = 31
Thus,
The sample mean is 31.
