Answer 1

Answer: The standard form is (x - h)2 = 4p (y - k), where the focus is (h, k + p) and the directrix is y = k - p. If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an equation of (y - k)2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p.

The resting heart rates for 80 women aged 46–55 in a simple random sample are normally distributed, with a mean of 71 beats per minute and a standard deviation of 6 beats per minute. Assuming a 90% confidence level, what is the margin of error for the population mean? 0.66 1.10 1.31 1.73

Answers

Given:
Confidence level = 90%
mean = 71 beats per minute
standard deviation = 6 beats per minute

margin of error = z * δ / √n

where : δ - population of the standard deviation, n is the sample size ; z is the appropriate z value.

90% confidence level = 1.645 in z-value

margin of error = 1.645 * (6/√80) = 1.645 * (6/8.94) = 1.645 * 0.671 = 1.104

The margin of error is 1.10

i just want to see if i got the correct answer my answer was
b=-15

Answers

Yes, the answer to the given maths solution is indeed is b = -15

How to solve this mathematical problem

3(-15) = -45

-45 + 9 = -36

-36 - 16 = -52

so b = -15

Hence, your initial answer is correct.

Answer:

-27

Step-by-step explanation:

(-3)^3 = (-3) * (-3) * (-3) = 9 * (-3) = -27

Answer:

-27

Step-by-step explanation:

In order to find the answer to this question you have to multiply the exponent by itself three times.

$-3^3 = -3*-3*-3$

Remember that a negative times a negative is a positive

$-3 * -3 = 9$

Remember a positive times a negative is a negative

$9 * -3 = -27$

$=-27$

Arrange the equations in the correct sequence to find the inverse of f(x)=y=3x/8+x

Answers

To find the inverse of the the function, it must be arranged in such a way that the independent variable be on the left side and the dependent variable on the right. So,
f(x) = y = 3x/ (8 + x)
y (8 + x) = 3x
8y + xy = 3x
8y = 3x - xy
8y = x (3 - y)
8y / (3-y) = x
x = 8y / (3 -y)

Therefore,
f-(x) = f(y) = x = 8y/ (3 - y)
