Find two consecutive numbers with a product of 121

Mathematics
1 answer:
Crank3 years ago
6 0
One number: x
Its consecutive:  x + 1

Product:

x(x+1)=121
x² + x - 121 = 0

Δ = 1² - 4.1.(-121)
Δ = 1+484
Δ = 485

As square root of 485 is not integer, do not exist two consecutive numbers with product of 121

What is equivalent to n – 4.6n – 3.3n + 2.8n
Ahat [919]

Answer:

4.1n

Step-by-step explanation:

Let's simplify step-by-step.

n−4.6n−3.3n+2.8n

=n+−4.6n+−3.3n+2.8n

Combine Like Terms:

=n+−4.6n+−3.3n+2.8n

=(n+−4.6n+−3.3n+2.8n)

=−4.1n

Find the median, Q1, Q3, interquartile range (IQR), and list any outliers. 2) 74, 63, 69, 62, 33, 79, 70, 60, 107, 119
e-lub [12.9K]

Answer:

Since the sample size is n=10 we can find the first quartile taking in count the first 5 observations from the data set ordered and we have this:

33  60  62  63  69

Q_1 =62

We can find the third quartile taking in count the last 5 observations from the data set ordered and we have this:

70  74  79 107 119

Q_3 =79

And finally the median can be calculated with the average of the two moddlie values and we got:

Median= \frac{69+70}{2} =69.5

And the IQr would be:

IQR = 79-62= 17

Step-by-step explanation:

Assuming that 2 is not part of the data we have:

74, 63, 69, 62, 33, 79, 70, 60, 107, 119

We can sort the values on increasing order and we got:

33  60  62  63  69  70  74  79 107 119

Since the sample size is n=10 we can find the first quartile taking in count the first 5 observations from the data set ordered and we have this:

33  60  62  63  69

Q_1 =62

We can find the third quartile taking in count the last 5 observations from the data set ordered and we have this:

70  74  79 107 119

Q_3 =79

And finally the median can be calculated with the average of the two moddlie values and we got:

Median= \frac{69+70}{2} =69.5

And the IQr would be:

IQR = 79-62= 17

What is the area of a regular octagon with a side length of 5 m and a distance from the center to the vertex of 6.5 m ?
horsena [70]
Answer is 120
Use the Pythagorean theorem to find the distance from the center to the side, 6.5²-(5/2)²=6², so the distance is 6. The perimeter is 5×8=40 then use ½(6)(40)=120

The lines shown below are parallel. If the green line have a slope of -3, what is the slope of the red line
abruzzese [7]

Answer:

The slope of the red line would also be -3

Step-by-step explanation:

This is because parallel lines have the same slope. So if the lines are parallel and the green one has a slope of -3, then the red one must also have a slope of -3.
