Answer:
one blue candle. 1/12 probability.
Step-by-step explanation:
if they are as likely as not to select a green candle, then there are 6 green ones. so now we have accounted for 11 if I am right, so only one can be blue
It is equally likely as not that the customer will select a blue candle.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Let the number of green candles on the tray be G, and the number of blue candles be B.
We know that there are 12 candles in total on the tray, so:
G + B = 12 (total number of green and blue candles is 12)
G/(G+B) = 1/2 (as the probability of selecting a green candle is equal to the probability of selecting a non-green candle)
We can use these two equations to solve for G and B:
G + B = 12
G = (12 - B)
Substituting into the second equation:
(12 - B) / (12 - B + B) = 1/2
(12 - B) / 12 = 1/2
12 - B = 6
B = 6
So there are 6 blue candles on the tray.
Since there are 12 candles in total, and 6 of them are blue, the probability of selecting a blue candle at random is:
P(selecting blue) = B / (G + B) = 6 / 12 = 1/2
Therefore,
It is equally likely as not that the customer will select a blue candle.
This means that the probability of selecting a blue candle is 50-50, which is neither impossible nor certain, but rather equally likely as selecting a green candle.

A company wants to learn about the number of its employees who visit the dentist for regular checkups. Which type of study will best help the company discover this information?
census
survey sample
observational study
experiment
Answer:
A. Census
Step-by-step explanation:
You would simply ask ALL of the employees at your workplace as to whether or not they visit the dentist for regular check-ups. Thus, it is a census.
The type of study which will be the best help the company discover this information is survey sample, the correct option is B
What is the sample space for a random experiment?Sample space is the set of all possible outcome the considered random experiment can result to.
Thus, suppose we toss a coin, then tossing a coin is a random experiment, and the sample space is {'head', 'tail'}. We ignore other outcomes like slant coin, or standing coin by assuming that coin is very thin to stand and always falls down.
We are given that;
The number of its employees who go to the dentist.
Now,
A census involves collecting data from every individual in a population, which can be time-consuming, expensive, and may not be feasible for a large company with a large number of employees.
An observational study involves observing individuals and collecting data without intervening or manipulating any variables. This type of study may not provide information about the number of employees who visit the dentist for regular checkups since it does not involve asking individuals directly about their behavior.
An experiment involves manipulating one or more variables to observe the effect on another variable. This type of study may not be appropriate for studying employee behavior related to dentist visits since it may not be ethical or practical to manipulate employees' behavior in this way.
A survey sample, on the other hand, involves selecting a subset of employees and asking them directly about their behavior related to dentist visits. This can be an effective and efficient way to gather information about the number of employees who visit the dentist for regular checkups.
Therefore, by sample space the answer will be survey sample.

Select all expressions that are equivalent to 8(5t + 7v).
A. 2(20t + 28V)
B.4(95 + 11v)
C.40t + 7v
D.40t + 56v
The expression 8(5t+7v) is equivalent to the expression 2(20t+28V) and 40t + 56v option (A) and option (D) is correct.
What is distributive property?The distributive property is the property that expresses the distributive law of algebraic multiplication. similarly, in polynomial expression we can use the distributive property for example we can write a(c+b) in the form of (ac+bc).
We have an expression:
= 8(5t+7v)
After using the distributive property, we get:
= 8×5t+8×7v
= 40t + 56v
Applying distributive property in the expression 2(20t+28v), we get:
= 2×20t+2×28v
= 40t+56v
The above expression is equivalent to the given expression.
Again applying distributive property in the expression 4(95+11v), we get:
= 4×95+4×11v
= 380+44v
The above expression is not equivalent to the given expression.
The expression 40t+7v is not equivalent to the given expression.
The expression 40t+56v is equivalent to the given expression.
Thus, the expression 8(5t+7v) is equivalent to the expression 2(20t+28V) and 40t + 56v option (A) and option (D) is correct.

a rectangular picture with a perimeter of 27 cm is glued in the center of a rectangular piece of cardboard. there is a 1 cm margin (of empty cardboard) all around the picture. what is the perimeter of the peice of cardboard
Answer:
31 cm
Step-by-step explanation:
A rectangle has 4 sides.
27 cm + 4 cm = 31 cm.
The perimeter is 31 cm.
If you are confused, to find perimeter you add all the sides up. That is why I added 1 + 1 + 1 + 1 / 4.
For inches or a different measure I recommend just converting it. You never mentioned the measure so I decided with cm.

Answer:
13.3 (rounded in the tenth place)
Step-by-step explanation:
equation: a^2 + b^2 = c^2
What we know :
a = 20^2 = 400
b = what we are looking for
c = 24^2 = 576
Our equation will be looking like :
20^2 + b^2 = 24^2
400 + b^2 = 576
Now we subtract 400 into 576
which equals 176 now we square root it
and get 13.2664 but we gotta square root it and that will lead you to have 13.3 as your answer
Answer:
31.24
Step-by-step explanation:
a^2+b^2=c^2
20^2=400
24^2=576
576+400=976
√976=31.24

A box contains fiction and nonfiction books. There are 22 fiction books in the box, which is 55% of the total number of books in the box. What is the total number of books in the box?
thank you for helping
Answer:
There are 40 books total
Step-by-step explanation:
you need to set a proportion
The first fraction is 55/100 it's over 100 because it's percent
the other fraction is 22/x the 22 is out of a total number so that's why it's on top and x because you don't know the total number of books
then you multiply diagonally
55×x= 22×100
55x=2,200
Then you solve it like a regular equation by dividing both sides by 55
x=40
Answer:
There are a total of 40 books in the box.

A. No, because two points with the same y-value have different x-values.
B. Yes, because the number of x-values is the same as the number of y-values.
C. Yes, because every x- and y-values is positive.
D. No, because two points with the same x- value have different y-values.
x = (y/2) - 1
Please help me find the answer.
Answer:
Step-by-step explanation:
Well you didn't give directions on what to solve for,
I'm gonna assume you want to solve for y
x = (y/2) - 1 (add 1 to both sides)
x + 1 = y/2 (multiply both sides by 2)
2(x + 1) = y (distribute the 2)
y = 2x + 2

April, x, slept 9 hours; Evelyn slept 2/3
less than that.
Evelyn slept _______________ hours. Write the equation as both a decimal and fraction.
live to be 80 years old and sleep 8 hours a day, How many years have I slept
Solution
A day has 24 hours
24 = 8 + 8 + 8
So you spent 1/3 of your time sleeping.
You can get the same answer if you do 8/24
8/24 = (8 ÷ 8) / ( 24 ÷ 8) = 1/3
All you need to do now is to find 1/3 of 80
1/3 of 80 = 1/3 × 80 = 80/3
80 / 3 = (78 + 2) / 3 = 78 / 3 + 2 / 3 = 26 + 2/3
So that is 26 years + ( 2/3 of a year)
What is 2 / 3 of a year?
Since 2 /3 of a year is a fraction of a year, the answer for 2 / 3 of a year will be in months.
1 year = 12 months.
Just find out what 2/3 of 12 is
2/3 of 12 is 2/3 times 12
2/3 times 12 = (2 times 12) / 3 = 24 / 3 = 8 months
Putting everything together, you slept for 26 years and 8 months during your lifetime.
Hope it helped!
