shortcut for finding the midpoint of a segment when one of its endpoints has coordinates (a, b) and the other endpoint is the origin.
Answer:
Hmm it has to be to divide the coordinates by 2
Step-by-step explanation:
Lets say you have (10, 8), and the other coordinate is (0, 0). If you divide 10 by 2 you get 5, and 8 by 2 you get 4, so what you get is (5, 4), which is the midpoint.

A hotel rewards club wants to randomly select 100 of its 5,000 members to participate in a survey. The club wants to determine if people’s opinions differ based on age. There are 2,200 members between the ages of 25 and 50, and there are 2,800 who are age 51 or older. The club decides to randomly select 44 members between the ages of 25 and 50, and 56 members ages 51 and older. Is the sample of 100 members a simple random sample? Yes, because the hotel rewards members were randomly selected for the sample. Yes, because each hotel rewards member has the same chance of being selected. No, because the sample of 100 is too small a sample to represent the population. No, because each sample of 100 does not have the same chance of being selected.
Answer:
No, because each sample of 100 does not have the same chance of being selected.
Step-by-step explanation:
Simple random samples require that every possible sample of the population has an equal chance of being selected. Because of the fact that certain ages are being picked at certain amounts, not every possible sample has the same chance of being selected, so this is not an SRS.
Answer:
D.
Step-by-step explanation:
No, because each sample of 100 does not have the same chance of being selected.

write an equation for the line that passes through (2,-5) and is parallel to the line 2y=3x+10
Answer:
[tex]y = \frac{3}{2} x-8[/tex]
Step-by-step explanation:
Firstly, let's get y by itself in the equation.
[tex]y = \frac{3}{2}x + 5[/tex]
Parallel lines have the same slope, but not the same y intercept. So we have an equation like this:
[tex]y = \frac{3}{2}x + b[/tex]
To find b (aka the y-intercept), we need to plug in the ordered pair into the equation like this:
[tex]-5 = \frac{3}{2}(2) + b[/tex]
Now solve:
[tex]-5 = \frac{6}{2} + b\\-5 = 3 + b\\-8 = b[/tex]
We have found the y-intercept, now we can write the full equation:
[tex]y = \frac{3}{2} x-8[/tex]

Answer:
£1.44
Step-by-step explanation:
We need to find the number of days it was due first.
26 Nov to 12 Dec: 16 days
1 day --- 9p
16 days --- 16 × 9p = 144p
= £1.44
Suppose you have seven different sweatshirts, and wish to wear a different one each day of the week. in how many ways can this be done? a. 49 different ways b. 1 different way c. 210 different ways d. 5040 different ways
The total number of ways or permutations in which that can be done are: d. 5040 different ways
To solve this problem the formula and the permutation procedure we must use is:
nPr = n! / (n-r)!
Where:
nPr = permutationn = total number of objectsr = number of selected objects! = factorial of the numberInformation about the problem:
n = 7 (sweatshirts)r = 7 (days)7P7 =?Applying the permutation formula we have:
nPr = n! / (n-r)!
7P7 = 7! / (7-7)!
7P7 = 7! / 0!
7P7 = 7! / 1
7P7 = 7 * 6 * 5 * 4 * 3 * 2 * 1 / 1
7P7 = 5040
What is permutation?It is the ordered arrangement of members belonging to a set with no repeats.

Answer:
They are similar by SSS similarity. TUV ~ QRS
Step-by-step explanation:
yes
Answer:
ΔTUV ~ ΔQRS
Step-by-step explanation:
The sides on the smaller triangle are 15, 25, and 30.
The sides of the larger triangle are 42, 70, and 84.
15*X = 42
X = 2.8
25 * 2.8 = 70
30 * 2.8 = 84
Since all sides of the larger triangle are 2.8 times the sides of the smaller triangle, the two triangles are similar.

Answer:
2/1
Step-by-step explanation:
Formula for slope is (y2 - y1)/ (x2 - x1)
In this case, it is (8 - 4)/ (5 - 3)
Which is evaluated to be 4/2
And simplified to 2/1.
Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answer:
See attached graph for rise and run lines
Slope = -1
Step-by-step explanation:
The slope-intercept equation form of a line is given by
y = mx + b where m = slope and b the y-intercept
rise/run is the slope of the line and is given by Δy/Δx where Δy represents the change in y values and Δx the corresponding change in x values
To calculate slope, take any two points on the line, find the difference between their y values and divide them by the change in x values
Two points I have chosen are (-3, 0) and (0, -3)
[tex]\textsf{{Slope}}=\dfrac{\ensuremath{-3}-0}{0-(-3)}=\dfrac{-3}{3}=-1[/tex]
We can see from the graph that the y-intercept ie where the line crosses the y axis i s-3
So the equation of the line is y = -1x - 3

3(9x - 6) = 4x + 10
What is the value of X In the equation
Answer:
Step-by-step explanation:
23(9x-6) = 4x +10
207x - 138 = 4x +10
203x = 148
x = 148/203
or
3(9x-6) = 4x +10
27x -18 = 4x + 10
27x - 4x = 10 + 18
23x = 28
x= 28/23
what is 0.3 repeating as a decimal?
a. 1/3
b. 1/9
c. 3/100
d. 3/10
Answer:
a
Step-by-step explanation:
if <1 and <2 are a linear pair then find the value of x’ if m<1 = 1/3(27x-6) and m<2 = 1/2(6x-20).
Answer:
16
Step-by-step explanation:
Remark
Linear Pair means two angles add to 180. They have a base and a transversal in common.
Equation
1/3(27x - 6) + 1/2(6x - 20) = 180 Remove the brackets
Solution
9x - 2 + 3x - 10 = 180 Collect like terms
12x - 12 = 180 Add 12
12x - 12 + 12 = 180 + 12 Combine
12x = 192 Divide by 12
12x/12/ = 192/12
x = 16

the coordinates of a and b are –7 and 9. the coordinates of c and d are –4 and 12. are a b and c d congruent? if yes, what is the length of each segment?
Line segment AB and CD both are congruent with the length of 16 units.
We have been given two line segment AB and CD of whose coordinates are :
A = -7 , B = 9 and C = -4 , D = 12
The distance formula is given as |x2 – x1|
Therefore the length of AB = |9 – (-7)|
= 9 + 7
= 16
The length of CD = |12-(-4)|
= 12 + 4
= 16
Note that when two line segments are congruent then their distance is equal.
Thus both the line segment AB and CD are congruent with a length 16 unit.
