<span>Let l equal the length of the rectangle
</span><span>width of a rectangle is 10 mm shorter than its length
</span>
<span>a. Write an expression for the width in terms of the length?
</span> w = l - 10
<span>b. Write an equation for the perimeter in terms of l.
P = l + l + (l-10) + (l-10)
P =4l - 20
</span><span>c. Solve the equation, clearly indicating the length of the rectangle.
</span> P =4l - 20
244 = 4l - 20
4l = 244 + 20
4l = 264
l = 284/4
l = 66
<span>d. Solve for the width of the rectangle. Clearly indicate the width of the rectangle.
</span>w = l - 10
w = 66 - 10
w = 56
I think the answer is 3,-7
Answer:
4% is a statistic and 1% is a parameter
Step-by-step explanation:
First, let's remember the differences between parameters and statistics:
Parameters are values that describe data of the entire population.
Statistics are values that describe data from a sample.
The value of 1% refers to "all of the parts", which is the population of over 1 million parts, thus 1% is a parameter.
The value of 4% refers to the "100 selected", which is the sample of 100 parts, thus 4% is a statistic.
Therefore, 4% is a statistic and 1% is a parameter.
Given:
Weight of one peach = 65 grams
Number of peaches in a box = 100
Cost of peach per kilogram is AED.10.
To find:
How much you have to pay?
Solution:
We know that,
Total weight of box = Weight of one peach × Number of peaches in a box
= 65 × 100
= 6500 grams
1000g = 1 kg
1 g = 0.001 kg
6500 g = 6500 × 0.001 kg
= 6.5 kg
Now,
Cost of 1 kg = AED.10
Cost of 6.5 kg = 6.5 × AED.10
= AED.65
Therefore, you have to pay AED. 65.
