(a) Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their wate

Anon25 [30]

Answer:

The margin of error (E) $=0.49$

Step-by-step explanation:

Given,

mean $\bar{x}=6.88$

standard deviation $\sigma=1.90$

sample size $n=41$

$90\% \quad \text{confidence interval}$

Critical value $=\frac{z_\alpha}{2}\quad \quad\quad[\because\;\alpha=1-\text{confidence interval}]$

$=1-0.90$

$\Rightarrow \alpha=0.1$

Critical value $=\frac{z_{0.1}}{2}$

$=z_{0.05}$

$=1.645$

The margin of error (E) $=\frac{z_\alpha}{2} \times\frac{\sigma}{\sqrt{n} }$

$=1.645\times\frac{1.90}{\sqrt{41} }$

$=0.49$

Hence, The margin of error (E) $=0.49$

I need help with slope (8th grade)

Triss [41]

Answer:

(y1-y2)/(x1-x2)

Step-by-step explanation:

if you have two points from the graph then you can use them to find the slope, for example:

(2,3) and (0,5)

you would take the first point and put it in a fraction (and the second point) but the x goes on the bottom and the y goes on the top:

3/2 and 5/0

Next you put them together minusing one of the equations, but make sure that the two coordinates line up (it doesn't matter which one, in the order):

3-5/2-0

Then you solve:

-2/2

-1

which means that -1 is the slope for this

(the "/" is a fraction bar, in case you didn't already know that)

If Sarah's mom drive 20 miles to work, drives 2,000 miles to New York and she lives in Rhode Island. How many total feet did she

mafiozo [28]

To solve this problem, you first have to add the total miles driven.

2000 + 20 = 2020

Then, you have to convert miles into feet. There are 5280 feet in a mile, so you multiply that by 2020.

5280 * 2020 = 10665600

Therefore, the total feet driven is 10665600. I hope this helped, good luck!

Which equations can be used to find the lengths of the legs of the triangle? Select three options. 0.5(x)(x + 2) = 24 x(x + 2) =

KatRina [158]

The equations that can be used to find the lengths of the legs of the triangle are as follows:

100 = (x + 2)² + x²
24 = 0.5 × (x + 2)(x)
x² + 2x - 48 = 0

<h3>How to find the equation of a right triangle?</h3>

The equation that can be used to find the length of the leg of the right triangle uses Pythagoras theorem,

Therefore,

c² = a² + b²

where

c = hypotenuse side
a and b are the other legs

Therefore,

10² = (x + 2)² + x²

100 = (x + 2)² + x²

Therefore, using the area of a triangle,

area of a triangle = 1 / 2 bh

where

b = base
h = height

Therefore,

area of the triangle = 1 / 2 × (x + 2)(x)

24 = 0.5 × (x + 2)(x)

24 = x² + 2x / 2

cross multiply

48 = x² + 2x

x² + 2x - 48 = 0
