According to a recent survey, 47 percent of the people living in a certain region carry a certain genetic
trait. People from the region will be selected at random one at a time until someone is found who carries
the genetic trait. Let the random variable X represent the number of people selected to find one person
who carries the genetic trait. How many people from the region can we expect to be selected to find one
person who carries the genetic trait?

Answer: w=210

Step-by-step explanation:

Answer:

W = 210

[tex]\frac{210}{6}=35[/tex]

Step-by-step explanation:

just multiply the two numbers:

6 x 35 = 210

so , 210/6 = 35

so basically W = 210

Answer:

A and D

Step-by-step explanation:

I could be wrong but the solutions are the points of intersection between the two functions. By looking at it. I can see that its about -3.3 and 5.2

Hope this helps!

The x-values are approximate solutions to the equation f (x) = g(x) that is -3.3 thus the correct option is A.

Function is a type of relation, or rule, that maps one input to specific single output.,Functions which repeats their values after a fixed interval, are called periodic function.

WE have been given the function x as

f (x) = g(x)

Therefore,

3(17x-6.5) = 108

Then Divide each side by 3;

3/3(17x-6.5) = -108/3

17x - 6.5 = -36

Add 6.5 to each side;

17x-6.5+6.5 = -36+6.5

17x = 42.5

Divide by 17;

17x/17 = -42.5/17

x = -3.3

The x-values are approximate solutions to the equation f (x) = g(x) that is -3.3 thus the correct option is A.

Answer: 730 calories

Step-by-step explanation:

Since the function is given as: 30w+70 and Polly's dog, Otis, weighs 22 kilograms.

The amount of calories that Otis need each day to stay healthy will be:

= 30w + 70

= 30(22) + 70

= 660 + 70

= 730 calories

The point (x, y) = (3, -4) represents the solution of the given system of equations.

Please check the attached graph.

Step-by-step explanation:

Given the system of equations

[tex]y\:=\:-\frac{3}{2}x\:-\:3[/tex]

[tex]y\:=\:-x\:-\:1[/tex]

Please check the attached graph of the given system of equations

From the graph:

Point of Intersection:

It is clear from the attached graph that the two lines intersect at the point (-4, 3).

i.e. at x = -4, y = 3

Therefore, the point (x, y) = (3, -4) represents the solution of the given system of equations.

Answer:

82

Step-by-step explanation:

Answer:

It would be 70

Step-by-step explanation:

First step: Divide 156 by 2

156 / 2 =  78

Second Step: The half of 156 is 78. Now we have 78 laptops and desktops, and as we know the question says that  "there are 8 more laptops than desktops", the next step to follow is to subtract 8 from 78 (Desktops) and add 8 to the 78 (Laptops).

78 - 8 = 70 Desktops  

78 + 8 = 86 Laptops

Hope this helps :)

Answer:

Ratio of lengths is 1:3

Ratio of areas is 1:9

Step-by-step explanation:

Firstly, we need the units to be same

Mathematically, 1 yard = 3 feet

A length of 1/4 yards = 1/4 * 3 = 3/4 feet

A width of 1/4 yards = 1/4 * 3 = 3/4 feet

The ratio of the length of the tile to the length of the board

that would be;

1/4 : 3/4 = 1: 3

Let’s now work with area

Mathematically, area in both cases is length * width

For the board, we have that;

3/4 * 3/4 = 9/16 square feet

For the tile, we have that;

1/4 * 1/4 = 1/16 square feet

so the ratio of the tile area to the board area will be;

1/16 : 9/16 = 1: 9

Step-by-step explanation:

150% of what number is 49

Can be written as;

1.5x = 49

( To find the percent of a number, one has to move the decimal back two spaces on the percent ( because a percent is out of 100), and then multiply by the number)

Use inverse operations to solve;

1.5x = 49

/1.5     /1.5
