Three people, Adam, Becky and Charley, each lie 1/3 of the time at random, otherwise they tell the truth. A fair coin is flipped, and they all see it. They all say it is heads. What is the probability the coin was actually tails?
[tex] \frac{1}{3} [/tex]
to find:the probability of the coin.
solution:lie:[tex]( \frac{1}{3} ) \times ( \frac{1}{3}) \times ( \frac{1}{3} )[/tex]
[tex] = \frac{1}{27} [/tex]
there's 1/27 chance of them to lie.
truth:[tex]( \frac{2}{3} ) \times ( \frac{2}{3} ) \times ( \frac{2}{3} )[/tex]
[tex] = \frac{8}{27} [/tex]
there's 8/27 chance that all of them told the truth.
probability:[tex]( \frac{8}{27} ) \div (( \frac{8}{27} ) + ( \frac{1}{27} ))[/tex]
[tex] = \frac{8}{9} [/tex]
therefore, between those two chances, it's an 8/9 chance it's actually Heads.

Help its timed 35 points
someone help me solve this
Answer:
Looking at the given points we know that it is going to be rectangle because we have 4 points. Therefore the figure is a rectangle and the area formula would be [tex]A=l*w[/tex].
You can look at the attached graph and what we see is that our width of the rectangle is from [tex]y=-4[/tex] to [tex]y=3[/tex] which means that our height is 7 units wide. We can also see that our length starts at [tex]x=-1[/tex] and ends at [tex]x=4[/tex] making us have a length of 5 units.
We then plug in the values and solve
[tex]A = 7\ units * 5\ units[/tex]
[tex]A = 35\ units^2[/tex]
Therefore, the area of our rectangle is [tex]35\ units^2[/tex]

The hypotenuse of a right triangle measures 2 square root 15 centimeters and its shorter leg measures 2 square root 6
centimeters.
What is the measure of the larger acute angle of the triangle? Round your answer to the nearest
tenth of a degree.
Answer:
50.8°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between side lengths and trig functions for a right triangle. Here, you are given the short side and the hypotenuse, and asked for the largest acute angle.
__
The short side is adjacent to the largest acute angle, so the relevant relation is ...
Cos = Adjacent/Hypotenuse
cos(β) = (2√6)/(2√15) = √0.4
The angle measure is found using the inverse cosine function:
β = arccos(√0.4) ≈ 50.8°
The larger acute angle is about 50.8°.

The correct statement is the first one. g(x) exceeds f(x) by 72.
Which statement is true?
By looking at the table, we can see that f(x) is a linear function and g(x) is an exponential function, such that:
f(x) = 10 + 3x
g(x) = (1/2)^x
By evaluating these functions in x = -6 we get:
[tex]f(-6) = 10 - 3*6 = -8[/tex]
[tex]g(-6) = (1/2)^{-6} = 64[/tex]
The difference is:
g(-6) - f(-6) = 64 + 8 = 72
Then the correct option is the first one, g(x) exceeds f(x) by 72.

3. a Paul is thinking of a number that is greater than 10 and less than 20. What is the probability
that the number is not a prime number? Express your answer as a fraction only.
The probability that the number is not a prime number is 5/9.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Paul is thinking of a number that is greater than 10 and less than 20.
So, the prime number between 10 and 20 are 11, 13, 17, 19.
So, the probability that the number is not a prime number
= ( 9- 4)/ 9
= 5/9
Hence, the probability that the number is not a prime number is 5/9.

by 40 students. Pepperoni pizza was
preferred by 28 students. Based on the
results, how many of the 340 students can
be expected to prefer cheese pizza?
Answer:
200 students

Bryan brought his series set of Rowan and the Dragon Quest to a secondhand store to sell. He was paid cash for all 5 books in the set. Before he left, Bryan used $29.75 of his earnings to purchase a used e-reader. He had $2.75 remaining. What was the value of each book in the set?
The value of each book in the set will be $6.5 when he sold his books to the second hand store.
What is profit and loss?When we sell any product above its cost price then there will be profit if the selling price is less then the cost price then there will be loss on the product.
here the total cost of the books sold will be given as:-

Based only on the information given in the diagram, which congruence
theorems or postulates could be given as reasons why A DEF= AJKL?
Check all that apply.
D
O A. LL
B. HL
C. LA
D. ASA
E. SAS
OF. AAS
The option (C) LA and (D) ASA are correct because two angles and one side are the same.
What is the congruent triangle?Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
From the triangle DEF and triangle JKL
∠D = ∠J (given)
∠F = ∠L (given)
ED = KJ (given)
∴ Triangle DEF and triangle JKL are congruent by the ASA
ΔDEF≅ΔJKL
Also:
∠F = ∠L (given)
ED = KJ (given)
ΔDEF≅ΔJKL by LA
Thus, the option (C) LA and (D) ASA are correct because two angles and one side are the same.

150 books are divided into 3 stacks. The 1st one has 30 more than the 2nd stack, 2nd stack has twice as many books in the 3rd stack. How many books are there in 3rd stack? (N represents the number of books in the 3rd stack.)
======================================================
Explanation:
N = number of books in the 3rd stack2N = number of books in the 2nd stack, since there are twice as many books here.2N+30 = add on 30 to the previous amount to get the number of books in the first stackIn other words,
1st stack = 2N+302nd stack = 2N3rd stack = NN is some positive whole number.
Add up all those expressions and set the sum equal to the 150 books total. Solve for N.
(1st stack) + (2nd stack) + (3rd stack) = total
(2N+30) + (2N) + (N) = 150
(2N+2N+N) + 30 = 150
5N + 30 = 150
5N = 150-30
5N = 120
N = 120/5
N = 24 which is the number of books in the 3rd stack
2N = 2*24 = 48 is the number of books in the 2nd stack.
2N+30 = 2*24+30 = 48+30 = 78 books in the 1st stack
Check:
1st+2nd+3rd = 78+48+24 = 150
The answer is confirmed.
