<h3><u>Answer</u> :- </h3>

c) 0.01

<h3><u>Solution</u> :-</h3>

To Write percentage in decimal or fraction we divide it by 100

therefore,

\begin{gathered}\\\implies\quad \sf 2\% = \frac{2}{100} \\\end{gathered}

\begin{gathered}\\\implies\quad \sf 2\% = 0.02 \\\end{gathered}

Half of 0.02 = \sf\frac{1}{\cancel2} \times\cancel{0.02}

\implies\boxed {0.01}

lakkis [162]

Answer:

a) 320 students

b) 25 students

Step-by-step explanation:

Number of 18-years old in the survey:

(We add all  frequency points for each line)

0 + 30 + 20 + 60 + 70 + 40 + 60 + 40 + 0 = 320 students

Number of 18 year old spending between 25 and 35 minutes: 40 + 65 = 105

Number of 12 year old spending between 25 and 35 minutes: 30 + 50 = 80

105 - 80 = 25 students

#20 four times the sum of number. and 15 is a least20. Let X represent the number. :find ball possible values for X
gayaneshka [121]
For this case what we have to take into account is the following variable:
 x = represent the unknown number
 We now write the following inequality:
 "four times the sum of number and 15 is at least 20"
 4 (x + 15)> = 20
 We clear the value of x:
 (x + 15)> = 20/4
 (x + 15)> = 5
 x> = 5 - 15
 x> = - 10
 The solution set is:
 [-10, inf)
 Answer:
 
all possible values for X are:
 
[-10, inf)

frosja888 [35]

Answer:

In explanation

Step-by-step explanation:

272 for part A because say you took a test out of 850 and you got a total of 272 of them right then you would of gotten a 32%

200 for 2 because if 75% of them liked pop music and 150 teenagers what the number of teenagers surveyed then that means 200 of them were surveyed because 150 out of 200 is 75%

I don't know the last one because if you had anything there only could get a 100%(im sorry for this one it's a little confusing.

Hope this helps have a great afternoon:)

Find the exact area of a circle with a dimeter of 5 yards. Use 3.14 for pi
kenny6666 [7]

Answer:

A = 6.25(pi)

A ~ 19.63495

Step-by-step explanation:

The formula for finding the area of a circle is;

A = (pi)r^2

Where (A) represents the area of the circle, (pi) represents the value (3.1415...) and (r) represents the radius of the circle. As per its definition, the diameter is the largest cord or line segment that can be drawn through a circle, the diameter always passes through the center of a circle. The radius ( a line segment that can be drawn from the center of the circle to any side of the circle) is always half of the diameter.

This means that the radius for the given circle is (2.5), since (5÷2=2.5)

Substitute these values into the equation and solve for the area of the circle.

A = (pi)r^2\\\\A = (pi)(2.5)^2\\\\A = (pi)6.25\\

A ~ 19.63495
