What is the equation of the line represented by the table below? X -2 -1 0 1 2 - y 16 11 6 1 -4 O A. y = -5x+9 OB. y = -5x+6 O C

Nina [5.8K]

Option (c) is the correct answer

The equation y = -5x + 6 is represented by the given table i.e.

x -2 -1 0 1 2

y 16 11 6 1 -4

Given, a table

x -2 -1 0 1 2

y 16 11 6 1 -4

Now, we have to find the equation of the line, satisfying the given values

As, the equation

y = -5x + 6 satisfying the given set of values,

So, the equation y = -5x + 6 is represented by the given table.

Hence, the equation y = -5x + 6 is represented by the given table.

Find the lateral surface area of this

Ksenya-84 [330]

Answer:

$A=157.07\ cm^2$

Step-by-step explanation:

Given that,

The radius of a cylinder, r = 5 cm

Height of the cylinder, h = 5 cm

We need to find the lateral surface area of the cylinder. The formula for the lateral surface area of the cylinder is given by :

$A=2\pi r h$

Put all the values,

$A=2\pi\times 5\times 5\\\\=157.07\ cm^2$

So, the lateral surface area of the cylinder is $157.07\ cm^2$ .

In a group of equal number of men and women 10% men and 45% women are suffering from Malaria.What is probability a peraon select

Kaylis [27]

Answer:

The probability a person selected random is not suffering from Malaria is 0.725.

Step-by-step explanation:

Denote the events as follows:

X = a person is suffering from Malaria

M = a man

W = a woman

The information provided is:

P (M) = P (W) = 0.50

P (X|M) = 0.10

P (X|W) = 0.45

Compute the probability a person selected random is suffering from Malaria as follows:

$P(X)=P(X|M)P(M)+P(X|W)P(W)$

$=(0.10\times 0.50)+(0.45\times 0.50)\\\\=0.05+0.225\\\\=0.275$

Then the probability a person selected random is not suffering from Malaria is:

P (X') = 1 - P (X)

= 1 - 0.275

= 0.725
