Answer:

23/50 or 0.46

Step-by-step explanation:

probability of girls owning a bicycle 60/100=3/5

probability of girls no owning one is 1-3/5=2/5

same method for boys 70/100=7/10

probability for not is 3/10

to find the probability that only one does you would do..

(3/5*3/10)+(2/5*7/10)

which equals 23/50 or 0.46

Answer:

x= 3 and -1

Step-by-step explanation:

[tex]f(x) = {x}^{2} - 2x - 3[/tex]

add three to both sides

[tex]3 = {x}^{2} - 2x[/tex]

figure out what half of -2 is

half of -2 is (-1) than square that (-1)^2=1

the 1 is what you add to both sides

[tex]3 + 1 = {x}^{2} - 2x + 1 \\ 4 = {(x - 1)}^{2} [/tex]

than take the square root of both sides

[tex] \sqrt{4} = \sqrt{ {(x - 1)}^{2} } [/tex]

this than equals

+2=x-1

than to find the x values

2=x-1

+1 +1

3=x

-2=x-1

+1 +1

-1=x

Step-by-step explanation:

The median of the given set {86, 24, 65, 65, 24, 24} is 44.5.

To find the median of the given set of numbers: 86, 24, 65, 65, 24, 24, we need to first arrange the numbers in ascending order:

24, 24, 24, 65, 65, 86

Now, there are six numbers in the set. Since there is an even number of data points, the median is the average of the two middlemost values.

The two middlemost values are 24 and 65.

Median = (24 + 65) / 2 = 89 / 2 = 44.5

So, the median of the given set is 44.5.

Answer:

A geometric sequence is a sequence of numbers such that the ratio of any two consecutive terms is always the same. This ratio is called the common ratio of the sequence.

In this case, the common ratio is 3/2 and the first term is 6. The nth term of a geometric sequence can be found using the formula:

a_n = a_1 * r^(n-1)

where a_n is the nth term, a_1 is the first term, and r is the common ratio.

Substituting the given values, we have:

a_8 = 6 * (3/2)^(8-1) = 6 * (3/2)^7

Calculating, we find that the 8th term is:

a_8 = 6 * (3/2)^7 = 6 * (9/2) = 27

Therefore, the 8th term is 27.

Step-by-step explanation:

On solving the provided question, we can say that - y proportional to  as the cube of s, y = ks3, then  8 = k * 23 => k = 1 then y  = 1 * 53 = 125

If two numbers are directly proportional, then as one quantity grows by a specific percentage, so does the other quantity by the same percentage. As an illustration, as gas costs rise, the price of food may also increase. If the ratio of two values x to y never changes, then x and y are said to be directly proportional to one another. example: Let's say you spend Rs. 50 on two pens. 4 pens cost 100 rupees each. If the ratio of two numbers, x and y, is greater than 1, then the two values The value of y1 is constant.

Since y proportional to  as the cube of s, y = ks3.

8 = k * 23 => k = 1

then y  = 1 * 53 = 125

Answer:

No, it is not a proportion

Step-by-step explanation:

10/12 and 40/64 is not a proportion since although the numerator is constant because when multiplied by 4, it gives us 40, however, when you multiply 4 by 12, you get 48, therefore, it is not a proportion since the changes in the value of a proportion must be constant in both the numerator and denominator.

Answer:

The other complementary angle measures 40 degrees.

Step-by-step explanation:

Given that one of the angles of a pairs of complementary angles is 50 degrees, to find the ratio of the pair of complementary angles, the following calculation must be performed, knowing that the sum of two complementary angles is equal to 90 degrees:

X + 50 = 90

X = 90 - 50

X = 40

Therefore, the other complementary angle measures 40 degrees.

The circumference of the garbage can will be 20 x π inches

The circumference of a circle or oval in geometry is its perimeter. That is, if somehow the circle were expanded out and squared out to a line segment, the perimeter would be the lengths of the arc. The curve distance around any closed image is more often referred to as the circumference.

Let 'r' be the radius of the circle that is 10 inched.

The circumference of the circle will be

C = 2πr units

The radius of the garbage can is 10 inches. Then the circumference of the garbage can is calculated as,

C = 2πr

C = 2 x πx 10

C =  20 x π inches

The circumference  will be 20 x π inches.

Answer:

Step-by-step explanation:

4^2 x 5^2 - 18^2

PEMDAS is our acronym for order of operations: Parentheses, exponents, multiplication, division, addition, subtraction.

Since we have no parentheses, we'll calculate the numbers and exponents (PEMDAS) first. "to the power of 2" is also called "squared" and means multiplying that number by itself.

(4x4) x (5x5) - (18x 18)

=16 x 25 - 324

Now we multiply: (PEMDAS)

= 400 - 324

then subtract: (PEMDAS)

=76

Answer:

76

Step-by-step explanation:

See 4^2 = 4x4 = 16

5^2 = 5x5 = 25

18^2 = 18x18 = 324

So it is

16 x 25 - 324

On solving the value of provided question we can say that - the value of the slope intercept y = -3.

The point on the y-axis where the slope of the line passes is known as the intersection point in mathematics. the location on a line or curve where the y-axis crosses that point. This is demonstrated by putting y = mx+c as the equation for the straight line, where m denotes the slope and c the y-intercept. In the intercept form of the equation, the slope (m) and y-intercept (b) of the line are highlighted. The slope is m, and the y-intercept is b for equations in the intercept form (y=mx+b). Additionally, certain equations may be recast to seem like slope intercepts. For instance, if y=x is rewritten as y=1x+0, the slope becomes 1 and the y-intercept becomes 0.

Answer:

60.092%

Step-by-step explanation:

For this problem, we will simply create a ratio to find the difference created between the prices, and subtract this from 1 (100%) to find the percent decrease.

$19.95 / $49.99 = 0.39908

1 - 0.39908 = 0.60092

Given that we take away the difference from the price from the percent of the whole, we find that the price decrease is 60.092%.

Thus, we have found the percent decrease.

When all liabilities have been paid for a business, what is left over are referred to as the stockholders' equity.

After all liabilities have been paid, a company's residual assets are referred to as its stockholders' equity. This amount is computed by deducting total liabilities from total assets, or alternatively, by adding share capital and retained earnings and deducting treasury stock.

Total Assets - Total Liabilities = Shareholders' Equity

The aforementioned equation is known as the fundamental accounting equation and is fairly simple to apply. The value of all obligations is subtracted from the total amount of assets on the balance sheet.

SE is therefore the owners' remaining claim to the assets after all debts have been paid. Total assets less total liabilities gives a company's shareholder equity. Shareholder equity includes retained earnings as well as any invested capital.

The constant of proportionality is 3

Answer: To compare the level of support for the new after-school club between teachers and students, we can calculate the percentage of individuals in each group that responded "yes" to the proposal.

For teachers: 13 out of 20 is equivalent to 13/20 = 0.65 or 65%

For students: 37 out of 50 is equivalent to 37/50 = 0.74 or 74%

Based on the percentage of individuals in each group that responded "yes," we can see that students are more in favor of the new after-school club than teachers. 74% of students responded "yes" to the proposal, while only 65% of teachers responded "yes."

It's worth mentioning that it's important to keep in mind that this comparison is based on the sample size of teachers and students that responded to the survey and not the whole population, also if the sample size isn't representative of the population and not randomly selected it can't be generalized.
