Answer:

Fraction of composite numbers = 6/10

Fraction of prime numbers = 4/10

Step-by-step explanation:

A composite number can be defined as a positive integer that will be formed when we multiply two smaller positive integers. It can also be said to be a positive integer that has at least one divisor of which 1 and itself are not included.

Thus, it means that the set of numbers given to us which is;

(11, 12, 13, 14, 15, 16, 17, 18, 19, 20), the composite numbers are;

12, 14, 15, 16, 18, 20

This is because each of them have at least one divisor that is neither itself or 1.

Thus, we have 6 out of the 10 numbers as composite.

Fraction of composite numbers = 6/10

Now, a prime number is a number that are only divisible by itself and 1.

Thus,from the given set, the prime numbers are; 11, 13, 17 & 19

We have 4 out of 10 numbers as prime numbers.

Thus, fraction of prime numbers = 4/10

Answer:

139

Step-by-step explanation:

First we need to find diameter 132/3.14=42 rounded

Then we halve it to find radius 42/2=21

Formula for area is radius x radius x 3.14

21 x 21 = 441 x 3.14 = 138.74 round up is 139

Answer:

18.8 feet, 59.1 feet to the nearest tenth

Step-by-step explanation:

The diameter is the line drawn that divides the circle into two while the circumference is the perimeter of the circle. Both are a measure of the radius of the circle.

The diameter D = 2r where r is the radius of the circle

The circumference = 2Πr = ΠD where Π = 22/7

Given that the circular fountain has a radius of 9.4 feet

Its diameter =  2 × 9.4 feet = 18.8 feet

The circumference = 22/7 × 18.8 feet

=59.09 feet

≈ 59.1 feet to the nearest tenth

Answer:

yea

Step-by-step explanation:

Yes.

16 could also be written as 16.0, or 16.00 or even 16.00000.

16.4 could also be written as 16.40, or 16.400.

And of course, you know 4 is greater than 0.

This is why 16.4 is greater.

When you add a decimal to a number, it always makes it larger. its like saying 16 and 4 tenths.

Answer:

y = 3/4x + 1 and 3x - 4y= -4

Step-by-step explanation:

I dont feel like explaining but just trust me bro

The Equation of parallel line is y= 3/7 x - 2/7.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

We have equation 3x – 4y = 7 and passes through (-4, -2).

Writing the given equation in slope intercept form as

3x = 7 +4y

4y = 3x- 7

y= 3/7 x - 4/7

so, the slope of parallel line is 3/7.

and, passes through (-4, -2).

y= 3/7 x +b

-2 = 3/7(-4) +b

-2 = -12 /7 + b

b = -2/7

So, the Equation of line is y= 3/7 x - 2/7.

I think the one that represents a even function is cos(x)

Answer:

The cosine is an even function which means that if (x,y) is on the graph of the function so too is the point (-x,y). Since y corresponds to cos(x) then this means that cos(-x) = cos(x).

Answer:

244

Step-by-step explanation:

Number of insects at time [tex]t[/tex] = 0 are 100.

Rate of growth of insects = [tex]\frac{2t}8[/tex] insects per day

Time, Number of days = 24 days

To find:

Number of insects or size of insect population after 24 days.

Solution:

Given that rate of growth of insects = [tex]\frac{2t}8[/tex] insects per day

We are given that, [tex]t[/tex] = 24 days

Rate of growth =

[tex]\dfrac{2\times 24}{8} = 2\times 3 = 6[/tex]

Growth in Insect population after 24 days = [tex]24\times 6 = 144[/tex]

Initial population = 100

Therefore, the answer is:

The size of insect population after 24 days = 100 + 144 = 244

Answer:

2 3/8

Step-by-step explanation:

-7 1/8 = -(7*8 + 1) / 8 = -57/8

-9 1/2 = - (9*2 + 1) / 2 = - 19/2

simplifying

= -57/8  - (-19/2)

= -57/8 + 19/2

= lcm of 2 ,8 is 8

=  (-57 + 4*19) / 8

= (-57 + 76) / 8

= 19 / 8     ------> (19 = 8*2 + 3)

= 2 3/8

Answer: you read the ? and u answer

Step-by-step explanation:

Answer:

Solution,

First term (a) = 25

Common difference (d) = Second term - first term = 20 - 25 = -5

Now,

nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n

The nth term of the series is 30 - 5n

Answer:

The nth term will be:

[tex]a_n=-5n+30[/tex]

Step-by-step explanation:

Given the sequence

25, 20, 15, 10, 5​

An Arithmetic sequence has a constant difference 'd' and is defined by

[tex]a_n=a_1+\left(n-1\right)d[/tex]

Computing the common difference of all the adjacent terms

[tex]25,\:20,\:15,\:10,\:5[/tex]

[tex]20-25=-5,\:\quad \:15-20=-5,\:\quad \:10-15=-5,\:\quad \:5-10=-5[/tex]

As the difference between all the adjacent terms is the same and equal to

[tex]d=-5[/tex]

Also, the first term is:

[tex]a_1=25[/tex]

Hence, the nth term will be:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=-5\left(n-1\right)+25[/tex]        ∵ [tex]a_1=25[/tex], [tex]d=-5[/tex]

[tex]a_n=-5n+30[/tex]

Therefore, the nth term will be:

[tex]a_n=-5n+30[/tex]
