Answer:

-1/9, 1/9

Step-by-step explanation:

If we represent this with an equation, we get 3 + |-9x| = 4. Subtract 3 from both sides and we get |-9x| = 1. There are two solutions to this, 1/9 and -1/9, since they both multiply to a number whose absolute value is 1. (-9 * 1/9 = -1, 9 * 1/9 = 1. -1 has an absolute value of 1.)

How do you divide 400 by 10 to the power of 3

Ivanshal [37]

10 to the power of 3 is 1000, and 400 divided by 1000 is 0.4 because you move the decimal place over 3 in the number 400 to get 0.4.

An electric sale gives a reading equal to the true weight plus a random error that isnormally distributed with mean 0 and standa

Pepsi [2]

Answer:

a) 95% confidence interval estimate of the true weight is (3.026, 3.274)

b) 99% confidence interval estimate of the true weight is (2.944, 3.356)

Step-by-step explanation:

Confidence Interval can be calculated using M±ME where

M is the mean of five successive weightings (3.150)

ME is the margin of error from the mean

And margin of error (ME) can be calculated using the formula

ME= $\frac{t*s}{\sqrt{N} }$ where

t is the corresponding statistic in the given confidence level and degrees of freedom(t-score)

s is the standard deviation of the random error (0.1)

N is the sample size (5)

Using the numbers 95% confidence interval estimate of the true weight is:

3.150± $\frac{2.776*0.1}{\sqrt{5} }$ ≈3.150±0.124

And 99% confidence interval estimate of the true weight is:

3.150± $\frac{4.604*0.1}{\sqrt{5} }$ ≈3.150±0.206

sladkih [1.3K]

This ODE is separable; we have

$\dfrac{\mathrm dy}{\mathrm dt}=ky\implies\dfrac{\mathrm dy}y=k\,\mathrm dt$

Integrating both sides gives a general solution of

$\ln|y|=kt+C\implies y=e^{kt+C}=Ce^{kt}$

B is the only choice that is applicable.
