Each square below represents one whole.
What percent is represented by the shaded area?
Answer:
160%
Step-by-step explanation:
Because the first square (the one to the left) is shaded to the brim, it represents 100%.
The second square (the one to the right) is shaded only until the 6th row, we can say that it is shaded 6/10 rows, or 60%.
Lastly, add the percentages of the two squares => 100% + 60% = 160%
If you flip two coins 64 times, what is the best prediction possible for the number of times
both coins will land on heads?
I need help quick this is a math unit test and it’s not 32 !
Answer:
The best prediction possible for the number of times both coins will land on heads is 16.
Step-by-step explanation:
For each time the two coins are flipped, there are only two possible outcomes. Either they both land on heads, or they not. Coin flips are independent, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
On a trial, probability of two heads.
Each trial has two coins, each with 0.5 probability of landing on heads. So the probability of two heads on a trial is:
[tex]p = (0.5)^2 = 0.25[/tex]
64 times
This means that [tex]n = 64[/tex]
What is the best prediction possible for the number of times both coins will land on heads?
The expected value. So
[tex]E(X) = np = 64*0.25 = 16[/tex]
The best prediction possible for the number of times both coins will land on heads is 16.

Answer:
x = 31 13/27
Step-by-step explanation:
108% of what number is 34
that is equal to
108% of x = 34
108% * x = 34
108/100 * x = 34
you can change the fraction into a reciprocal so that the variable can stand alone.
x = 34 * 100 / 108
x = 3400/108
x = 31 13/27

An artist mixes paint to make new colors.
She uses 13 cup of red paint and 13 cup of yellow paint to make a batch of orange paint.
If the artist has 2 cups of red paint available and 3 cups of yellow paint available,
how many batches of orange paint can she make?
Enter your answer in the box.
Answer:
The artist can make six batches of orange paint and it remains one cup of yellow paint
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of red paint for one batch of orange paint = 1/3 of a cup
Amount of yellow paint for one batch of orange paint= 1/3 of a cup
Amount of red paint available = 2 cups
Amount of yellow paint available = 3 cups
2. How many batches of orange paint can she make?
2 cups of red paint = 6/3 = 6 batches of orange paint
3 cups of yellow paint = 9/3 = 6 batches and it remains one cup of yellow paint
The artist can make six batches of orange paint and it remains one cup of yellow paint

how do i find the measure of R or whatever big confushion help
Answer:
m∠R= 87°
Step-by-step explanation:
The angles in a polygon add up to (n-2)180
(5-2)180= 540°
You can set up an equation to add all the angles together equaling 540°.
Once you solve for x, plug that back into the formula for the angle of R(7x-11)
