The ratio of men to class is 0.41.

We have a class of 10 men and 14 women.

We have to find out what is the ratio of men to the class.

Yes, a : b is same as [tex]\frac{a}{b}[/tex]. Here, ' a ' is called Antecedent and ' b ' is called Consequent.

In the question given -

Total number of men in the class , n(m) = 10

Total number of students in class, n(c) = 24

Ratio of men to class = [tex]\frac{n(m)}{n(c)}[/tex] = [tex]\frac{10}{24}[/tex] = 0.41

Hence, the ratio of men to class is 0.41.

Final answer:

The ratio of men to the entire class of 10 men and 14 women is 5:12, simplified by dividing the numbers of men and total students by the greatest common divisor.

Explanation:

The question asks to find the ratio of men to the entire class. The class has a total of 10 men and 14 women, which means the class size is 10 (men) + 14 (women) = 24 students.

To calculate the ratio of men to the entire class, divide the number of men by the total number of students: Ratio = 10 (men) / 24 (students). This can be simplified by dividing both numbers by the greatest common divisor, which is 2, giving us a simplified ratio of 5 (men) to 12 (students).

The ratio of men to the class is therefore 5:12.

Final answer:

The expected number of heads and tails when tossing a coin 10 times is 5 each.

Explanation:

If you toss a coin ten times:

Expected number of heads: 5

Expected number of tails: 5

This is because for each toss, the probability of getting a head is 0.5 (50%) and the same for a tail. Over multiple tosses, the outcomes tend to approach these expected values.

Answer:  The required slope-intercept form is [tex]y\leq 3x+21.[/tex].

Step-by-step explanation:  We are given to write the following inequality in slope-intercept form :

[tex]-6x+2y\leq 42~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We know that

the slope-intercept form of an inequality of the given form is as follows :

[tex]y\leq mx+c,[/tex] where m is the slope and c is the y-intercept.

From inequality (i), we have

[tex]-6x+2y\leq 42\\\\\Rightarrow 2y\leq6x+42\\\\\Rightarrow y\leq\dfrac{6}{2}x+\dfrac{42}{2}\\\\\Rightarrow y\leq 3x+21.[/tex]

Thus, the required slope-intercept form is [tex]y\leq 3x+21.[/tex].

The ratio of 1 foot 4 inches to 1 yard is 16:36 or 4:9.

To find the ratio of 1 foot 4 inches to 1 yard, we first need to convert both measurements to the same unit. Since there are 3 feet in a yard and 12 inches in a foot, we can express both measurements in inches.

1 foot is equivalent to 12 inches.

Therefore, 1 foot 4 inches is:

1 [tex]\times[/tex] 12 + 4 = 12 + 4 = 16 inches

Now, since there are 3 feet in a yard, and each foot has 12 inches, 1 yard is equivalent to:

3 [tex]\times[/tex] 12 = 36 inches

Now we have both measurements in inches, and we can set up the ratio:

16 inches: 36 inches

Therefore, the simplified ratio is:

16:36.

We can further simplify this ratio by dividing both numbers by 4:

(16/4):(36/4) = 4:9.

Answer:

[tex]2.99x+12.99y=43.92[/tex]

Step-by-step explanation:

Hanna shops for socks that cost $2.99 for each pair.

And blouses that cost $12.99 each.

Let x represent the number of pairs of socks purchased.

Let y represent the number of blouses purchased.

So, the cost for x socks will be [tex]2.99x[/tex]

And cost of y blouses will be [tex]12.99y[/tex]

Total amount spent by Hanna = $43.92

So, the equation that will model this situation will be:

[tex]2.99x+12.99y=43.92[/tex]

To solve for x in 5x² - 34x = -24, set the equation to equal 0, factor the equation, and find the possible values for x. In this case, the solutions are x = 6/5 and x = 4.

This is a problem in algebra, more specifically quadratic equations. To solve for x in the equation 5x² - 34x = -24, you first need to set the equation to equal zero: 5x² – 34x + 24 = 0.

Next you can factor the equation to find the possible values for x. In this case, the factored form is 5x² - 20x - 14x + 24 = 0 which further simplifies to 5x(x - 4) - 6(x - 4) = 0, and then (5x - 6)(x - 4) = 0.

When you set each factor equal to zero, you find the possible solutions for x. From 5x - 6 = 0, x = 6/5; and from x - 4 = 0, x = 4. Therefore the solutions are x = 6/5 and x = 4.

Option C) is correct

Step-by-step explanation:

Given :  y is the daily production cost at a canning company such that [tex]y=650-15x+0.45x^2[/tex] wherex is the number of canned items .

To find : Minimum daily production cost

Solution :

[tex]y=650-15x+0.45x^2[/tex]

On differentiating both sides with respect to x, we get

[tex]\frac{\mathrm{d} y}{\mathrm{d} x}=-15+0.9x[/tex]

On putting [tex]\frac{\mathrm{d} y}{\mathrm{d} x}=0[/tex] , we get [tex]-15+0.9x=0\Rightarrow 15=0.9x\Rightarrow x=\frac{15}{0.9}=\frac{150}{9}=\frac{50}{3}[/tex]

We get intervals as \left ( -\infty , \frac{50}{3}\right )\,,\,\left ( \frac{50}{3},\infty  \right )[tex]\left ( -\infty , \frac{50}{3}\right )\,,\,\left ( \frac{50}{3},\infty  \right )[/tex]

For [tex]x=0\epsilon \left ( -\infty ,\frac{50}{3} \right )[/tex] , [tex]f'(0)=-15< 0[/tex]

For [tex]x=16\epsilon \left ( \frac{50}{3},\infty  \right )[/tex] , [tex]f'(18)=-15+0.9(18)=-15+16.2=1.2> 0[/tex]

Therefore, [tex]y=\frac{50}{3}[/tex] is a point of minima.

So, minimum cost is equal to [tex]y\left ( \frac{50}{3} \right )[/tex]

[tex]y\left ( \frac{50}{3} \right )=650-15\left ( \frac{50}{3} \right )+0.45\left ( \frac{50}{3} \right )^2=650-250+125=\$ 525[/tex]

The probability that the kicker makes his first two kicks is 0.63, or 63%.

Let's denote the events:

A: The kicker makes his first kick

B: The kicker makes his second kick

Given:

P(A) = 0.7 (probability that the kicker makes his first kick)

P(B|A) = 0.9 (probability that the kicker makes his second kick given that he made his first kick)

To find the probability of both events A and B occurring (the kicker making his first two kicks), we can use the multiplication rule of probability:

P(A and B) = P(A) * P(B|A)

Substituting the given probabilities, we have:

P(A and B) = 0.7 * 0.9 = 0.63

Therefore, the probability that the kicker makes his first two kicks is 0.63, or 63%.

The probability that the kicker makes his first two kicks is 0.63, or 63%.

To find the probability that the kicker makes his first two kicks, we need to multiply the probabilities of each individual kick.

The kicker has a 70% chance of making his first kick, which means he has a 30% chance of missing it.

If the first kick is made, his success rate rises to 90%. So, the probability of making the second kick, given that he made the first kick, is 90%.

To find the probability of both kicks being made, we multiply the probability of making the first kick (0.7) with the probability of making the second kick given that the first kick was made (0.9).

0.7 * 0.9 = 0.63

Therefore, the probability that the kicker makes his first two kicks is 0.63, or 63%.

Ques 1)

We know that if a graph is stretched by a factor of a then the transformation if given by:

    f(x) → a f(x)

Also, we know that the translation of a function k units to the right or to the left is given by:

  f(x) →  f(x+k)

where if k>0 then the shift is k units to the left

and if k<0 then the shift is k units to the right.

Here the graph of f(x) ​is transformed into the graph of g(x) by a vertical stretch of 4 units and a translation of 4 units right.

This means that the function g(x) is given by:

[tex]g(x)=4f(x-4)\\\\i.e.\\\\g(x)=4(-3(x-4))\\\\i.e.\\\\g(x)=-12(x-4)\\\\i.e.\\\\g(x)=-12x+48[/tex]

Answer:

the answer is C. -5/7

the measure of angle ABC (m∠ABC) is 130 degrees. it's essential to recognize that the sum of the angles along a straight line is always 180 degrees.

In this case, we have two angles, 2x and 5x+5, forming a straight line with an unknown angle (m∠ABC). So, we set up the equation:

2x + 5x + 5 = 180

Next, combine the like terms on the left side:

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 175/7

x = 25

Therefore, the measure of angle ABC = 5x + 5

= 5(25) + 5

=130 degree

So, the measure of angle ABC (m∠ABC) is 130 degrees.

In mathematics, specifically geometry, the least angle measure by which a regular, symmetric figure can be rotated to map onto itself is usually 90°. This concept falls under the umbrella of rotational symmetry.

The question is about rotation of objects in geometry. To identify the least angle measure for a figure to map onto itself, we need to know the shape of the figure. However, assuming the figure is regular and symmetric (a square or a rectangle for example), the least angle measure by which it can be rotated to map onto itself is 90°.

It's important to remember the concept of rotational symmetry. A figure has rotational symmetry if it can be rotated less than 360° around a central point and still appear the same. For instance, a regular rectangle or square has a rotational symmetry of 90°, since we can rotate it 90 degrees and it appears the same.
