The slower stone will take 3.33 seconds if the faster stone takes 10s to return to the ground.
What is linear acceleration?It is defined as the rate of change in linear velocity with respect to time. It is also known as linear acceleration.
From the motion equation:
s = ut + at²/2
From the data given:
s = 0
0 = 3u(10) - 9.8(10)²/2
After solving:
u = 16.33 m/s
To calculate for time:
s = ut + at²/2
s = 0
u = 16.33
0 = 16.33t + 9.8t²/2
t = 3.33 seconds
Thus, the slower stone will take 3.33 seconds if the faster stone takes 10s to return to the ground.
The complete question is:
Two stones are thrown vertically upward from the ground, one with three times the initial speed of the other.

What is meant by centroid theorem?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

Suppose points P,Q, and R are collinear, with point Q between points P and R . Describe a plan for a proof that the reflection of points P,Q, and R in a line preserves collinearity and betweenness of points.
The points P,Q, and R are collinear points is proved by the property that Congruent Figures' Corresponding Parts are Congruent.
What is meant by collinearity?Collinear points are those that are within the same straight line or on the same plane. In Euclidean geometry, two or more points on a line that are close to or the far from one another are referred to as collinear.
If three items are arranged in a straight line, the things are collinear.More astonishingly, the word collinear has been applied to straightened things, which means something is "in a row" or "in a line."As, per the given question, the description for the reflection of points P,Q, and R to form collinear points are described below.
Draw the points P,Q, and R so they are collinear, with Q between P and R. Connect P to P', Q to Q', as well as R to R' by reflecting P, Q, and R. Display the quadrilateral congruent that results. Congruent Figures' Corresponding Parts are Congruent.If two or more points lie on the same line, they are said to be collinear in geometry. As a result, collinear points are indeed the points that lie on the an one straight line.

a. Write the point-slope form of the line that passes through A(-3,12) and B(9,-4) . Use point A in the equation.
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)
y - 12 = -4/3(x + 3)

According to the question, the probability of the event in which rolling a pair of dice and not getting a 3 is as follows:
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

there are three age groups in a competition.
john wants to do a survey of the competitors.
he uses a stratified sample of exactly 50 competitors according to each age group.
work out the number of competitors in each age group that should be in his stratified sample of 50
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.

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°

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
