Answer:
B
Step-by-step explanation:
If you graph y^2/361 + x^2/169=1 you will get the same graph depicted in the equation.
Answer:
Minimum value = 2
Maximum value = 26
Lower quartile = 4
Median = 14
Upper quartile = 20.5
Step-by-step explanation:
Five number summary:
- Minimum value
- Maximum value
- Lower quartile
- Median
- Upper quartile
Assuming the stem is the tens column and the leaves are units, the data values are:
2, 2, 3, 5, 7, <u>13, 15</u>, 16, 20, 21, 24, 26
Minimum value = 2
Maximum value = 26
<u>Median</u> - middle value
As there is an even number of data values, the median is the mean of the 6th and 7th data values.
Median = (13 + 15) ÷ 2 = 14
<u>Lower quartile</u>
As there is an even number of data values, the lower quartile is the mean of the 3rd and 4th data values.
Lower quartile = (3 + 5) ÷ 2 = 4
<u>Upper quartile</u>
As there is an even number of data values, the upper quartile is the mean of the 20th and 21st data values.
Lower quartile = (20 + 21) ÷ 2 = 20.5
Eighty, decreased by three times an number, is the same as five times the number, increased by eight. Then the number is 9
<h3><u>
Solution:</u></h3>
Given that eighty, decreased by three times an number, is the same as five times the number, increased by eight
<em><u>To find: the number</u></em>
Let the required number be "a"
Let us break the given sentence
<em>Eighty decreased by three times an number = five times the number increased by eight</em>
Here "times" represents multiplication and "decreased" represents subtraction and "increased represents "addition"
80 - three times "a" = 5 times "a" + 8
80 - 3a = 5a + 8
80 - 8 = 5a + 3a
8a = 72
<h3>a = 9</h3>
Thus the required number is 9
Pretty sure the answer is 2
