Answer: x-intercept 5 and y-intercept 8.

Step-by-step explanation: As you work through it, you will discover that algebra, geometry, and trigonometry ... AB. For each of the following, find coordinates for the midpoint of AB: ... Given that 2x − 3y = 17 and 4x + 3y = 7, using mental math (that is, without using ... Find a and b so that ax + by = 1 has x-intercept 5 and y-intercept 8.

8 pencils cost 3.44 What is the unit of one pencil?

amid [387]

Hey there!

All we have to do is divide the price ($3.44) by how many pencils there are (8)

$3.44 ÷ 8 = $0.43

So, each pencil costs $0.43

Hope this helps you!

Always remember you are a Work Of Art!

A field is 910 yards by 300 yards. What is the greatest number of rectangle lots of 120 yards by 65 yards that can be places on

solniwko [45]

Let R = greatest number of rectangular lots.

R = (910 • 300)/(120 • 65)

R = 273,000 ÷ 7800

R = 35

Answer:

$\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})$

And replacing:

$\mu_{\bar X}= 5$

And the deviation:

$\sigma_{\bar X}= \frac{0.283}{\sqrt{5}}= 0.126$

And the distribution is given:

$\bar X \sim N(\mu= 0.08, \sigma= 0.126)$

Step-by-step explanation:

For this case we have the following info given :

$\mu= 5. \sigma^2 =0.08$

And the deviation would be $\sigma = \sqrt{0.08}= 0.283$

For this case we select a sample size of n = 5 and the distirbution for the sample mean would be:

$\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})$

And replacing:

$\mu_{\bar X}= 5$

And the deviation:

$\sigma_{\bar X}= \frac{0.283}{\sqrt{5}}= 0.126$

And the distribution is given:

$\bar X \sim N(\mu= 0.08, \sigma= 0.126)$
