From a group of 11 people, you randomly select 2 of them. What is the probability that they are the 2 oldest people in the group? Give your answer as a fraction.
Answer:
2/11
Step-by-step explanation:
Probability is the LIKELIHOOD of an event.
According to the word problem, there are 11 people in total and 2 of them are being selected.
The probability of them being the 2 oldest people is 2 in 11, or 2/11.
Segment AB, with endpoints A(-6,9) and B(12, -3), is dilated by a scale factor of 2/3 centered at the origin.
What are the coordinates of A'?
Enter your answer as an ordered pair, using parentheses and a comma, like this: (42,53)
The coordinates of A' after the dilation is (-4,6)
How to determine the coordinates of A'?The given parameters are:
A = (-6,9)
B = (12, -3)
Scale factor, k = 2/3
The coordinates of A' is then calculated as:
A' = A * k
This gives
A' = (-6,9) * 2/3
Evaluate the product
A' = (-4,6)
Hence, the coordinates of A' after the dilation is (-4,6)

A manufacturer claims that its new hand sanitizer reduces the number of days an average person is sick in a year. To test this claim, a researcher decided to conduct an experiment. The researcher randomly selected 300 people, divided into subject groups by age. Over the course of a year, all the subjects regularly used the hand sanitizer. At the end of the year, the researcher compared the number of days that the subjects in each group were sick.
Which statements about this experiment are true?
Answer:
The study uses blocking and random sampling.
Step-by-step explanation:
The statement with respect to the experiment should be true is that The study uses blocking and random sampling.
What is random sampling?It should be the part of the technique related to sampling where each and every sample should contain equivalent probability of being selected. The sample that should be selected on random basis should be mean to be non-biased with respect to the total population.

A kayaker traveled 4 5/6 miles during the first hour, and 1 1/3 miles more then the next hour. How far did he travel in 2 hours
Answer:
11 miles
Step-by-step explanation:
Given that :
Distance traveled in first hour = 4 5/6 miles
Distance traveled in the next hour = 4 5/6 + 1 1/3
Therefore, the total distance traveled in 2 hours equals :
4 5/6 miles + (4 5/6 miles + 1 1/3 miles)
29/6 + 29/6 + 4/3
L. C. M of denominator = 6
(29 + 29 + 8) / 6
= 66 / 6 miles
= 11 miles
Distance traveled in 2 hours =. 11 miles
The drama club sold bags of candy and cookies to raise money for the spring show. Bags of candy cost $8.00, and bags of cookies cost $2.50, and sales equaled $33.50 in total. There were 5 more bags of cookies than candy sold. Find the number of bags of candy and cookies sold by the drama club
Answer:
Number of bags of candy = 2
Number of bags of cookies = 7
Step-by-step explanation:
Let, number of bags of candy = X
So, Number of bags of cookies = X + 5
Cost of candy bag = $8
Cost of cookies bag = $2.5
Total sales = $33.50
So, Total cost of Candy Bags + Total cost of cookies bags = Total sales
= 8X + 2.5 ( X +5) = 33.50
= 8X + 2.5X + 12.5 = 33.50
= 10.5X = 33.50 - 12.5
= 10.5X = 21
X = 2
So, number of bags of candy = 2
Number of bags of cookies = 2 + 5 = 7

5, 2, and 3.
Answer:
Determine whether the set of lengths could form a triangle 5, 2 and 3. No it can not form a triangle.
Step-by-step explanation:
5 + 2 is greater than 3. 5 + 3 is greater than 2. 3 + 2 is not greater than 5
Answer:
No, the set of lengths - 5, 2 and 3 will not form a triangle.
Step-by-step explanation:
As we know,
The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

The sum of reciprocals is 2/3.
You don't need complex numbers to solve this, but if you try to find a and b you will need complex numbers.
Step-by-step explanation:
a+b = 2
a*b = 3
1/a + 1/b = x
(a*b)*(1/a + 1/b) = (a*b)x
b + a = (a*b)(x)
2 = 3x
x = 2/3
b = 2 - a
a*(2 - a) = 3
-a^2 + 2a = 3
-a^2 + 2a - 3 = 0
a^2 - 2a + 3 = 0
let's solve the quadratic equation
a^2 - 2a + 3 = a^2 - 2a + 1 + 2 = (a - 1)^2 + 2 = 0
(a - 1)^2 = -2
[tex]a_1 - 1 = \sqrt{2}i\\a_1 = 1+\sqrt{2}i\\\\a_2 - 1 = -\sqrt{2}i\\a_2 = 1 - \sqrt{2}i\\[/tex]
these options correspond to a and b from the original question.

Answer:
Answer:
JK = 18.8
Step-by-step explanation:
7/33 = 4/JK
132 = 7JK
JK = 18.86
Answer:
JK=18.8
Step-by-step explanation:
so we are given that ΔGHI ~ ΔJKL
GI~JL (because corresponding parts of similar triangles are similar)
so GI/JL=ratio of similitude=7/33
GH~JK (corresponding parts of similar triangles are similar)
and GH/JK=ratio of similitude
so:
GH/JK=GI/JL
subsitute known values
4/JK=7/33
cross multiply
7JK=132
divide
JK=132/7
simplify and round
JK≈18.8

3(2z + 3)
= -75
I need help ty
Answer:
= − 1 4
Step-by-step explanation:
Answer:
z = - 14
Step-by-step explanation:
Solving for z using basic algebra
3(2z + 3) = -75
Step 1 distribute the 3
3 * 2z = 6z
3 * 3 = 9
now we have 6z + 9 = -75
step 2 subtract 9 from each side
9 - 9 cancels out
-75 - 9 = -84
now we have 6z = - 84
step 3 divide each side by 6
6z / 6 cancels out
-84 / 6 = -14
we're left with z = -14
