Answer:
- <u><em>The height of the missing rectangle is 0.15</em></u>
Explanation:
The image attached has the mentioned <em>histogram</em>.
Such histogram presents the relative frequencies for the clases [0,1], [1,2],[2,3], [4,5], and [5,6] Silver in ppm.
Only the rectangle for the class [3,4] is missing.
The height of each rectangle is the relative frequency of the corresponding class.
The relative frequencies must add 1, because each relative frequency is calculated dividing the absolute class frequency by the total number in the sample; hence, the sum of all the relative frequencies is equal to the total absolute class frequencies divided by the same number, yielding 1.
In consequence, you can sum all the known relative frequencies and subtract from 1 to get the missing relative frequency, which is the height of the missing rectangle.
<u>1. Sum of the known relative frequencies</u>:
- 0.2 + 0.3 + 0.15 + 0.1 + 0.1 = 0.85
<u>2. Missing frequency</u>:
- 1 - 0.85 = 0.15
<u>3. Conclusion</u>:
- The height of the missing rectangle is 0.15
Answer is z=36
First find the ratio of the similar sides
55/44 = 1.25 ratio
Divide 45 by the ratio to find z
45/1.25 = 36
First find the ratio of the similar sides
55/44 = 1.25 ratio
Divide 45 by the ratio to find z
45/1.25 = 36
If the first term is 25 and the common difference is 4. Then the 97th term of the sequence will be 409.
<h3>What is a sequence?</h3>A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.
The sequence is given below.
25, 29, 33, ...., so on
Then the first term is 25. And the common difference is 4.
Then the 97th term will be given as
where
n = 97
a = 25
d = 4
Then we have
a₉₇ = 25 + (97 - 1)4
a₉₇ = 25 + 96 x 4
a₉₇ = 25 + 384
a₉₇ = 409
Then the 97th term of the sequence will be 409.
