If a certain machine makes electrical resistors having a mean resistance of 40 ohms and a standard deviation of 2 ohms, what is

Anna71 [15]

Answer:0.0668

Step-by-step explanation:

Given

mean of sample $\mu =40$

Standard deviation $\sigma =2$

For $n=36$ sample

Random variable $Z=\frac{X-\mu }{\frac{\sigma }{\sqrt{n}}}$

For combined resistance of 1458 ohm mean resistance of $\mu =\frac{1458}{36}=40.5$

$P(40.5$

$=P(\frac{40.5-40}{\frac{1}{3}}$

$=P(1.5$

$=1-P(Z\leq 1.5)$

$=1-0.9332$

$=0.0668$

2х - 4 = 3y<br> 5y - x =5

yawa3891 [41]

Answer:

x=5

Step-by-step explanation:

Lets first solve for y on both sides:

$2x-4=3y\\\frac{2x-4}{3}=y\\ y=\frac{2x-4}{3}$

$5y-x=5\\5y=5+x\\y=\frac{5+x}{5}$

Set the two equations equal to each other and solve for x:

$\frac{2x-4}{3}=\frac{5+x}{5}$

Multiple both sides by 3:

$2x-4=\frac{3(5+x)}{5}$

Multiply both sides by 5:

$5(2x-4)=3(5+x)$

Apply distributive property to both sides:

$10x-20=15+3x$

Add 20 to both sides:

$10x=35+3x$

Subtract 3x from both sides:

$7x=35$

Divide both sides by 7:
$x=5$

Hi guys how do u order decimals like this

Stels [109]

Answer:

Ascending Order: 0.432 < 0.5734 < 0.76373

Descending Order: 0.76373 < 0.5734 < 0.432

Step-by-step explanation:

Check the tenths place of the decimal number and order them accordingly. If the tenths place is the same for two decimal numbers, go on to the next corresponding place to compare their values.
