We refer to these occurrences as random phenomena or random experiments. These kinds of random events or experiments typically include probability theory. What, though, is a sample space? A sample space for the experiment is a collection of all such potential outcomes. In other terms, the sample space, which is typically represented by the letter S, is the collection or set of potential outcomes in a random experiment. When doing a random experiment, the sample space is represented.

4 is less than 5, so 4.241 is less than 4.25.

Given the numbers are 4.241 and 4.25.

Because 4.241 and 4.25 have the same units and tenth digit (4.2 = 4.2)

so we need to compare the hundredths place that is, 0.041 with 0.05.

A decimal's distance from one whole increases as it increases in size. A decimal is further away from one whole the smaller it is. The amount of digits in each decimal should be your primary point of focus. Each of them contains two digits, allowing for immediate comparison.

The number following the decimal point is called the hundredths place. Round up the number of hundredths if the third number after the decimal is 5 or above. Keep the hundredths number constant if the number in the third position after the decimal point is 4 or less.

0.041 < 0.05

hence we get 4.241 < 4.25

The factors of the equation x2y3 - 11x2y + 6y2 - 66 can be found by taking out the common terms.

x2y3 - 11x2y + 6y2 - 66

Let us take out the common from the first two terms.

Take out common from the last two terms.

[tex]\boxed{\begin{minipage}{4.3 cm}\underline{Circumference of a circle}\\\\ $C=\pi d$\\\\where $d$ is the diameter\end{minipage}}[/tex]

From inspection of the given diagram:

The perimeter of a two-dimensional shape is the distance all the way around the outside.

Therefore, the perimeter of the given shaded region is the sum of half the circumference of the larger circle, half the circumference of the smaller circle, and the two 5 cm ends.

[tex]\begin{aligned}\sf \implies Perimeter & = \sf \dfrac{1}{2} \pi (24) + \dfrac{1}{2} \pi (14) + 5 + 5\\& = \sf \dfrac{1}{2}(3.14)(24) + \dfrac{1}{2}(3.14)(14) +10\\& =\sf 37.68+ 21.98+10\\& =\sf 69.66\:\:cm\end{aligned}[/tex]

Therefore, the perimeter is 69.66 cm.

The perimeter of the shaded region is 12.56 times the radius of one of the semicircles.

To find the perimeter of the shaded region, we need to find the total length of all the boundaries.

The shaded region consists of two semicircles, so we can start by finding the circumference of each semicircle.

The formula for the circumference of a circle is C = 2πr.

Since we have two semicircles, we need to find the radius for each and then add the two circumferences together to get the total perimeter.

Let's say the radius of each semicircle is r.

Using the given value of π as 3.14,

the circumference of one semicircle is 2 * 3.14 * r = 6.28r.

Therefore, the total perimeter is 6.28r + 6.28r = 12.56r.

So, the perimeter of the shaded region is 12.56 times the radius of one of the semicircles.

Answer:

KL = 10

Step-by-step explanation:

Given:

 [tex]JL=26[/tex]

 [tex]KL=3x+7[/tex]

 [tex]JK=8x+8[/tex]

From inspection of the given diagram:

[tex]JK+KL=JL[/tex]

Substitute the given values into the found equation and solve for x:

[tex]\implies 8x+8+3x+7=26[/tex]

[tex]\implies 11x+15=26[/tex]

[tex]\implies 11x+15-15=26-15[/tex]

[tex]\implies 11x=11[/tex]

[tex]\implies \dfrac{11x}{11}=\dfrac{11}{11}[/tex]

[tex]\implies x=1[/tex]

Substitute the found value of x into the expression for KL:

[tex]\implies KL=3(1)+7[/tex]

[tex]\implies KL=3+7[/tex]

[tex]\implies KL=10[/tex]

Formula we use,

→ JK + KL = JL

Now the value of x will be,

→ (8x + 8) + (3x + 7) = 26

→ 11x + 15 = 26

→ 11x = 26 - 15

→ x = 11/11

→ [ x = 1 ]

Then the value of KL will be,

→ 3x + 7

→ (3 × 1) + 7

→ 3 + 7 = 10

Hence, the value of KL is 10.

If the points lie on straight line then, the points should be collinear.

We enter the values and check to see whether we receive a true statement, such as "10 Equals 10," to determine whether a point (x, y) is on the graph of a line. The point is not on the line if we obtain a result other than 6 = 4, as it does not meet the equation. Two lines will coincide if they have a same point and have the same slope. To put it another way, if A, B, and C are three points in the XY plane, they will all lie on a line, or three points will be collinear, but only if AB's slope and BC's slope are both equal.

The ratio HD:HA is 5/11 when the sides of a triangle are of lengths 13, 14, and 15.

When the lengths of all three sides are known, the geometry formula Heron's formula, which bears Hero of Alexandria's name, determines the area of a triangle. There is no need to first determine the angles or other distances in the triangle, unlike other triangle area formulas. Heron of Alexandria is credited with developing the Heron's formula, which determines the area of a triangle in terms of the lengths of its sides. If the side lengths are represented by the symbols a, b, and c: Area is equal to the square root of (a + b + c)/2, where s is half the perimeter.

By Heron's Formula, the area of this triangle is 84 Thus the height perpendicular to  AB  has a length of 11.2, and by the Pythagorean Theorem,  AE  and  EB  have lengths  6.6  and  8.4,  respectively. These lengths tell us that  C  is at.

The slope of  BC  is (0-11.2)/(15-6.6)=-4/3,  and the slope of  AD  is 3/4 by taking the negative reciprocal of -4/3.  Therefore, the equation of line  AD  can best be represented by  y=(3/4) x.

We next find the intersection of  CE  and  AD . We automatically know the  x -value; it is just  6.6  because  CE  is a straight line hitting  (6.6,0).  Therefore, the  y -value is at  (3/4)* 6.6=4.95.  Therefore, the intersection between  CE  and  AD  is at  (6.6,4.95) .

We also need to find the intersection between  BC  and  AD . To do that, we know that the line of  AD  is represented as  y=3/4x,  and the slope of line  BC  is  -4/3.  We just need to find line  BC 's y-intercept. So far, we have  y=-4/3x+b,  where  b  is a real y-intercept. We know that  B  is located at  (15,0),  so we plug that into the equation and yield  b=20.  Therefore, the intersection between the two lines is

(3/4)x=-(4/3)x+20

⇒9x=-16x+240

⇒25x=240

⇒x=9.6

Now y=(3/4)*x=(3/4)*9.6=7.2

⇒y=7.2

After that, we use the distance formula:  HA  has a length of

√(6.6-0)²+(4.95-0)²=√(1089/25)+(9801/400)

=√(1089*16+9801)/400

=√27225/400=√1089/16=33/4=8.25

and  HD  has a length of

√(9.6-6.6)²+(7.2-4.95)²=√(3)²+(36/5-99/20)²

=√(9)+(81/16)

=√225/16=15/4=3.75

So the ratio os HD:HA is

⇒3.75/8.25=15/33=5/11

Probability that the mother in this sample had a premature baby given that the mother admitted to smoking is 50 percent.

Likelihood is the part of science concerning mathematical depictions of how likely an occasion is to happen, or how likely it is that a suggestion is valid. The likelihood of an occasion is a number somewhere in the range of 0 and 1, where, generally talking, 0 demonstrates difficulty of the occasion and 1 shows conviction.

P (A) is the probability of an event “A”

n (A) is the number of favorable outcomes

n (S) is the total number of events in the sample space

The higher the likelihood of an occasion, the more probable it is that the occasion will happen. A straightforward model is the throwing of a fair coin. Since the coin is fair, the two results are both similarly likely; the likelihood of "heads" approaches the likelihood of "tails"; and since no different results are conceivable, the likelihood of by the same token "heads" or "tails" is 1/2.
