There are 10 people in the 16-18 group , 22 people in the 19-24 group and 18 people who are 25+ in the stratified sample.

A method of sampling from a population that can be divided into subpopulations is known as stratified sampling in statistics. When subpopulations within a larger population differ in statistical surveys, it may be desirable to sample each subpopulation separately.

From the given table we can calculate the total of population:

population = 120 + 250 + 200 = 570 people

Now since it is a stratified sample, the ratio of each age group is equal in the sample as in the population.

∴Number of people in the 16-18 group :

[tex]=\frac{120}{570} \times 50\\\\=10.52[/tex]

∴Number of people in the 19-24 group :

[tex]=\frac{250}{570} \times 50\\\\=21.929[/tex]

∴Number of people in the 19-24 group :

[tex]=\frac{200}{570} \times 50\\\\=17.543[/tex]

Now as 10.52 is closer to 10 than 17.54 is closer to 17 , we will round off 10.52 to 10.

Hence there are 10 people in the 16-18 group , 22 people in the 19-24 group and 18 people who are 25+  in the stratified sample.

If Tamika receives 20 rewards points just for signing up and she earns 10.5 points for each visit to the movie theater and she needs 167 points for a free movie ticket, then an equation to determine x, the number of visits Tamika must make to earn a free movie ticket is 10.5x + 20 = 167 and the value of x is calculated to be 14.

The number of visits Tamika must make can be determined by using a linear equation with one variable.

As,

reward points for signing up = 20

points for each visit = 10.5

points needed for free movie ticket = 167

If we consider x to be the number of visits required, then the linear equation can be given as,

10.5x + 20 = 167

Solving for x,

10.5x = 167 - 20

10.5x = 147

x = 147/10.5 = 14

Hence, the number of visits Tamika must make to earn a free movie ticket is equal to 14.

Based on the angles addition postulate, m∠UVW = 140°.

The angles addition postulate says that two smaller angles that is composite of a larger angle can be added together to give the measure of the larger angle.

Based on the angle addition postulate, the following equation that can be used to solve the problem given is derived below:

measure of angle XVW + measure of angle UVX = measure of angle UVW

Given the following:

measure of angle UVX = 76°

measure of angle XVW = 64°

Thus, using the above equation, we have:

64 + 76 = measure of angle UVW

140 = measure of angle UVW

measure of angle UVW = 140°

What is Probability?

The term probability means the study of the occurrence or the outcomes of the event. It is the measurement of the events that occurred during events. And many uncertain events cannot be measured.

Probability of not getting 3=  1 - P(getting three)/Total number of events

Probability of not getting 3=1-2/36 = 1-1.18 =17/18

Answer: 52x^200 + 4x+4x^4

Step-by-step explanation:

In Δ SZU, UJ = 9, VI = 3 , and ZT = 18 then the value of SJ = 6.

The triangle's centroid is the point where the three medians intersect. According to the centroid theorem, the centroid is 23 times the distance from each vertex to the midpoint of the opposite side.

The centroid has the unique property that the distance from a vertex to the centroid is twice that of the distance from the centroid to the midpoint of the side opposite that vertex for each median. In addition, the three medians of a triangle divide the triangle into six equal-area regions.

Given: In Δ SZU, UJ = 9, VI = 3 , and ZT = 18 .

Since ZV ≅ VU, Y is the midpoint of UZ and SV is a median of Δ ZSU. Similarly, points Y and T are also midpoints of SZ and SU, respectively, so YU and ZT are also medians. Therefore, point J is the centroid of

Δ ZSU and, according to the Centroid Theorem, SJ is 2/3 of SV.

SJ = 2/3 (SV)

= 2/3 (SJ + VJ)

simplifying the above equation, we get

(3SJ/2) - SJ = VJ

SJ/2 = 3

SJ = 6

Therefore, the value of SJ = 6.

The length of the third side will be equal to 5.2 units.

According to the Pythagorean Theorem, the hypotenuse square in a right-angled triangle equals the square of the sum of the other two sides.

This statement states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

This is a right-angled triangle which means that the missing length can be solved using the Pythagorean theorem:

c² = a² + b²

Where c is the hypotenuse, a and b are the other sides.

c =  6

The equation of the line in point-slope form, which passes through the pair of points located at A(-3 , 12) and B(9 , -4), is y - 12 = -4/3(x + 3).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Getting the slope of the two points: A(-3 , 12) and B(9 , -4).

m = (y2 - y1)/(x2 - x1)

m = (-4 - 12)/(9 - -3)

m = -16/12

m = -4/3

Using the point slope form, plug in the values of the slope and Point A to set up the equation.

(y - y1) = m(x - x1)

where m = -4/3 and (x1 , y1) = A(-3 , 12)

(y - 12) = -4/3(x - -3)
