Answer:
If we assume that the proportion of male and female internet users in the second study is the same as the first study (i.e., 60% female and 40% male), and that the percentage of male and female internet users who create their own blog is the same as the first study (i.e., 17% for male and 22% for female), then we can calculate the percentage of teen bloggers who are female and male.
First, we can calculate the number of male and female internet users in the second study:
Number of female internet users = 1000 x 0.5 x 0.6 = 300
Number of male internet users = 1000 x 0.5 x 0.4 = 200
Next, we can calculate the number of female and male teen bloggers in the second study, based on the percentages from the first study:
Number of female teen bloggers = 300 x 0.22 = 66
Number of male teen bloggers = 200 x 0.17 = 34
Finally, we can calculate the percentage of teen bloggers who are female and male:
Percentage of teen bloggers who are female = (66 / 1000) x 100% = 6.6%
Percentage of teen bloggers who are male = (34 / 1000) x 100% = 3.4%
Therefore, in the second study, 6.6% of teen bloggers would be female and 3.4% of teen bloggers would be male.
planets x, y and z take $360$, $450$ and $540$ days, respectively, to rotate around the same sun. if the three planets are lined up in a ray having the sun as its endpoint, what is the minimum positive number of days before they are all in the exact same locations again?
By using LCM, we find that the three planets x, y and z will be in the exact same locations again after $5400$ days.
To find the minimum positive number of days before the planets are all in the exact same locations again, we need to find the least common multiple (LCM) of the three given periods of rotation.
The prime factorization of each of the given periods of rotation is as follows
$360 =[tex]2^3 \cdot 3^2 \cdot 5$[/tex]
$450 =[tex]2 \cdot 3^2 \cdot 5^2$[/tex]
$540 =[tex]2^2 \cdot 3^3 \cdot 5$[/tex]
To find the LCM, we need to take the highest power of each prime factor that appears in any of the three factorizations. So the LCM is:
[tex]$LCM = 2^3 \cdot 3^3 \cdot 5^2 = 2^3 \cdot 27 \cdot 25 = 5400$[/tex]
Therefore, the three planets will be in the exact same locations again after $5400$ days.

What is fifteen divided by two hundred and eighty nine?
15 divided by 289 is approximately equal to 0.0519 or 519/10000. Fifteen divided by two hundred and eighty nine is a division problem that involves dividing 15 by 289. To solve this problem, we can use long division or a calculator.
Using long division, we start by dividing the first digit of the dividend (2) by the divisor (15). Since 2 is less than 15, we add a decimal point and a zero to the dividend and continue the process. We bring down the next digit (8) and divide 28 by 15, which gives us a quotient of 1 with a remainder of 13. We add a decimal point after the quotient and bring down the next digit (9) to get 139 as the new dividend. We divide 139 by 15, which gives us a quotient of 9 with a remainder of 4. We add a decimal point after the quotient and bring down the last digit (0) to get 40 as the new dividend. We divide 40 by 15, which gives us a quotient of 2 with a remainder of 10. Finally, we add a decimal point after the last quotient and write the remainder as a fraction over the divisor to get the final answer:
15 divided by 289 is approximately equal to 0.0519 or 519/10000.
In summary, fifteen divided by two hundred and eighty nine is a division problem that can be solved using long division or a calculator. The answer is a decimal or a fraction, depending on how the division is carried out.

The amount of time required for each of 100 mice to navigate through a maze was recorded. The histogram below
shows the distribution of times, in seconds, for the 100 mice.
Which of the following values is closest to the standard deviation of the 100 times?
(A) 2.5 seconds
(B) 10 seconds
(C) 20 seconds
(D) 50 seconds
(E) 90 seconds
The closest value to the standard deviation of the 100 times is (C) 20 seconds.
To determine the closest value to the standard deviation of the 100 times, we would need the actual histogram or the data points themselves.
In general, the standard deviation measures the spread or dispersion of a set of values. A higher standard deviation indicates a greater dispersion, while a lower standard deviation indicates a smaller dispersion.
Looking at the given options, (A) 2.5 seconds and (B) 10 seconds are relatively small values, which suggests a low dispersion among the times. On the other hand, options (D) 50 seconds and (E) 90 seconds are larger values, indicating a higher dispersion.
Option (C) 20 seconds falls in between the smaller and larger values. While it is difficult to determine the exact standard deviation without the data, option (C) of 20 seconds seems like a reasonable choice as it represents a moderate spread among the 100 times.
Therefore, the closest value to the standard deviation of the 100 times is (C) 20 seconds.

The cost of 5 skirts and 3 blouses is sh. , 750. Mueni bought three of the the skirts and one of the blouses for sh. 850. Find the cost of each item solve with formula
As per the unitary method, the cost of one skirt is sh 20 and the cost of one blouse is sh 550.
Let us assume that the cost of one skirt is x and the cost of one blouse is y. We can now form two equations based on the given information.
Equation 1: 5x + 3y = 1750
This equation represents the cost of 5 skirts and 3 blouses together, which is given as sh 1750.
Equation 2: 3x + y = 850
This equation represents the cost of 3 skirts and 1 blouse, which is given as sh 850.
To apply the unitary method here, we can first find the value of one skirt by dividing equation 1 by 5, and then find the value of one blouse by subtracting 3 times the value of one skirt from equation 2.
Dividing equation 1 by 5, we get:
x + (3/5)y = 350
Subtracting 3 times the value of one skirt from equation 2, we get:
y = 850 - 3x
y = 850 - 3(350/5)
y = 550
So, we have found the value of y, which is the cost of one blouse. Now, we can substitute this value of y in equation 1 to find the value of x, which is the cost of one skirt.
5x + 3(550) = 1750
5x + 1650 = 1750

There are 3 regular hecagons, one isocrles trapezoid, one triangle, one circle and one parallelogram. Use the provded measurements to find the area. You will need to use trigonometry to find some measurements
As per the concept of parallelogram, the area of the hexagons is 1237.9 cm², one isosceles trapezoid is 130 cm², one triangle is 60 cm², one circle is 78.5 cm².
Since we know the apothem is 10 cm, we can use the tangent function to find the length of the side:
tan(72) = side length / 10
Solving for the side length, we get:
side length = 10 * tan(72) ≈ 21.2 cm
Now that we know the side length, we can use the formula for the area of a regular polygon:
area of the hexagon = (5 x side length² x √(3)) / 2 ≈ 1237.9 cm²
Next, let's find the area of the isosceles trapezoid.
To find the area, we can use the formula:
area of the trapezoid = ((base1 + base2) / 2) x height
Substituting the given values, we get:
area of the trapezoid = ((12 + 14) / 2) x 10 = 130 cm²
Now, let's move on to the triangle. We are given the base (12 cm) and the height (10 cm). To find the area of a triangle, we can use the formula:
area of the triangle = (base x height) / 2
Substituting the given values, we get:
area of the triangle = (12 x 10) / 2 = 60 cm²
Next, let's find the area of the circle. We know that the diameter of the circle is equal to the height of the isosceles trapezoid (10 cm), so the radius is half of that:
radius = 10 / 2 = 5 cm
Using the formula for the area of a circle, we get:
area of the circle = π x radius² = π x 5² ≈ 78.5 cm²

a square has a side length of 3 1/2 inches. the scale factor of 2/3 was used to create a new square. what is the side length of the new square
Answer:
Step-by-step explanation:
The side length of the original square is 3 1/2 inches.
To find the side length of the new square, we need to apply the scale factor of 2/3 to the original side length.
To do this, we multiply the original side length by the scale factor:
(2/3) x 3 1/2
To multiply a fraction by a whole number, we can first convert the whole number to a fraction with a denominator of 1:
(2/3) x (7/2)
To multiply two fractions, we can multiply their numerators together and their denominators together:
(2/3) x (7/2) = (2 x 7) / (3 x 2) = 14/6
We can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2:
14/6 = (2 x 7) / (2 x 3) = 7/3
Therefore, the side length of the new square is 7/3 inches.
a rectangular container 12 cm long, 8 cm wide, and 36 cm high was one - third full. when some syrup from a bottle was poured into the container, it got half full. find the volume of the syrup poured from the bottle into the container in millimeters
when some syrup from a bottle was poured into the container, it got half full. The volume of the syrup poured from the bottle into the container in millimeters is 576,000 cubic millimeters.
Since for solving the problem we need to find the volume of the container in millimeters. We are given the length, breadth, and height which are 12 cm,8 cm, and 36 cm.Now the volume of the container is:
V = l x w x h = 12 cm x 8 cm x 36 cm = 3,456 cubic cm. Now we convert the above result into millimeters by multiplying by 1,000, so we get V= 3456 x 1000= 34560000 cubic mm
Now to find the volume of the syrup that was poured into the container, we know that the container was one-third full before the syrup was added and half full after the syrup was added.onsidering x to be the volume of the syrup poured from the bottle into a container and n to be the volume of the syrup in the container after it was added:
1/3(V) + x = 1/2(V), where v is the volume of the container in millimeters, so we substitute the calculated value of the volume we get :
=>1/3(V) + x = 1/2(V)
=>x = 1/2(V) - 1/3(V)
=> x = 1/6(V) = 1/6(3,456,000) = 576,000 cubic mm

Debra’s rectangular vegetable garden measures 9 1/3 yards by 12 yards. A bottle of garden fertilizer costs $14.79. If Debra needs to mix 1/8 cup of fertilizer with water for each square yard of her garden, how many cups of fertilizer does she need?
She needs 14 cups of fertiliser.
What is the area?
A two-dimensional figure's area is the amount of space it takes up. In other terms, it is the amount that counts the number of unit squares that span a closed figure's surface.
Area = length * width
Find the area of the garden:
Area = 9 1/3 * 12
= 28/3 * 12
= 112 yards²
Find the amount of the fertiliser needed:
1 yards² = 1/8 cup
112 yards² = 1/8 * 112 = 14 cups
She needs 14 cups of fertiliser.
