Let us assume the width of the rectangle = x cm
Then
The length of the rectangle = (x + 4) cm
It is already given that
Perimeter of the rectangle = 80 cm
Now we also know the formula for perimeter of a rectangle
Perimeter = 2 ( length + width)
80 = 2 (x + 4 + x)
80 = 2 (2x + 4)
80/2 = 2x + 4
40 = 2x + 4
Dividing both sides by 2 we get
20 = x + 2
20 -2 = x
x = 18
Then
Width of the rectangle = 18 cm
Length of the rectangle = (18 + 4) cm
= 22 cm
So the rectangle has a length of 22 cm and a width of 18 cm.

Hi there!
slope: -2/5
as you can see...
x= +-2
y=+5
<u><em>This means...</em></u>
if -4 is 10 then if you subtract twice it would be -2 and if you subtract by 5 in y then it would be 5..adding all together would be .
<em><u>1.Find the meaning:</u></em>
<em><u /></em><em><u /></em>
<em><u /></em><em><u /></em>
<em><u>2.Subtract the x and y:</u></em>
<em><u /></em><em><u /></em>
<em><u /></em><em><u /></em>
Therefore, the slope would be -2/5.
Answer:
The probability that the mean weight of a 24-bag case of potato chips is below 10 ounces is approximately 0.
Step-by-step explanation:
Let <em>X</em> = weight of potato chips in medium size bag.
The random variable <em>X</em> follows a Normal distribution with mean, <em>μ</em> = 10.2 ounces and standard deviation, <em>σ</em> = 0.12 ounces.
A sample of <em>n</em> = 24 bags of chips is selected.
Compute the probability that the mean weight of these 24 bags is less than 10 ounces as follows:
Thus, the probability that the mean weight of a 24-bag case of potato chips is below 10 ounces is approximately 0.
