While flipping a weighted coin, Latrell gets 4 heads and 2 tails. Based on experimental probability, how many of the next 3 flips should Latrell expect to come up heads?
Answer: 2 heads
Step-by-step explanation:
First, write the experimental probability as a fraction in simplest form.
P(heads)
=
heads
total
=
heads
heads+tails
=
4
4+2
=
4
6
=
2
3
The experimental probability is
2
3
.
We can predict the outcome of the second set of trials by assuming that the ratio will be the same as in the first set of trials. Write a proportion by setting the two ratios equal to each other, then solve.
2
3
=
n
3
2
3
(33)
=
n
3
(33) Multiply both sides by (33)
23
= 3n Simplify
6
= 3n Simplify
2
= n Divide both sides by 3
Based on experimental probability, Latrell should expect 2 of the next 3 flips to come up heads.

d) -6
Answer:
the correct answer is -6
Answer:
d)-6
Step-by-step explanation:
negative and positive is a negative in multiplication. and 6x6=36
so if you put 6(-6) you get -36
A 9 m ladder rests against the side of a wall. The bottom of the ladder is 1.5 m from the base of the
wall. Determine the measure of the angle between the ladder and the ground, to the nearest degree.
1 degree
80 degrees
53 degrees
10 degrees
9514 1404 393
Answer:
(b) 80°
Step-by-step explanation:
The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
The 1.5 meter distance to the wall is the side adjacent to the angle with the ground. The 9 m length of the ladder is the hypotenuse of the triangle modeling this situation.
cos(angle) = 1.5/9 = 1/6
angle = arccos(1/6) ≈ 80.4°
The angle between the ladder and the ground is about 80°.
_____
Additional comment
The Ladder Association recommends an angle of 75° for safety. At 80°, the ladder may have a tendency to tip the user backward.

Could someone please explain how to find the surface area of a pyramid?
You don't have to explain this specific problem, just the formula.
Answer:
The general formula for the total surface area of a regular pyramid is T. S. A. =12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.
Step-by-step explanation:
f(x) = 2x^2 - 5x - 15
g(x) = -2x - 1
find f(g(x)) ... somebody help me :(
Answer:
f(g(x)) = 8x² + 18x - 8
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(- 2x - 1)
= 2(- 2x - 1)² - 5(- 2x - 1) - 15
= 2(4x² + 4x + 1) + 10x + 5 - 15
= 8x² + 8x + 2 + 10x - 10
= 8x² + 18x - 8

Are 6/10 and 6/30 multiples of 3/20
Answer:
yes well kinda im pretty sure
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
6/30 and 6/10 are not multiples of 3/20 because you cant take 3/20 and multiply both the numerator and the denominator by one number and get 6/30 or 6/10 but a multiple would be like 6/20, 18/40, 30/100 and so on.

=35 cm^2
area of four triangles
=35 x 4 cm^2
=140 cm^2
area of the square
=10 x 10 cm^2
=100 cm^2
area of the polygon
=(100 + 140) cm^2

5. Adana made key chains for her friends out of string. She started with 2 feet of red string, 3-teet of
yellow string, and 5-feet of green string If Adana used a total of 8 3 feet of string on the key chains,
how much string remains unused?
Answer:
2 1/4
Step-by-step explanation:
SOL Review question 4
Adana made key chains for her friends out of string. She started with 2 1/6 feet of red string, 3 1/4 of yellow string, and 5 1/2 feet of green string. If Adana used a total of 8 2/3 feed of string on the key chains, How much string remains unused.
It would be 2 1/4 because you convert all the factions denominators to 12. 2 1/6 becomes 2 2/12, 3 1/4 becomes 3 3/12, 5 1/2 becomes 5 6/12, and 6 2/3 becomes 8 8/12. add 2 2/12, 3 3/12, and 5 6/12 and you get 10 11/12 and then you subtract 10 11/12 and 8 8/12 (10 11/12 - 8 8/12) and get 2 3/12. when you get that answer, convert it by 3 and you get 2 1/4.

Which is a common characteristic of both science and pseudoscience? experimentation the collection of information beliefs data
Answer:
collection of information
Step-by-step explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
Pseudoscience can be defined as a collection of theories, methodology, practices and beliefs about the universe that are mistakenly, purportedly or erroneously regarded as scientific but in true sense isn't backed up by evidence (facts) and fails to comply with any scientific model.
However, a common characteristic of both science and pseudoscience is that both fields deals with the collection of information.
In conclusion, pseudoscience is considered to be subjective while science is objective.

Step-by-step explanation:
Given that P(A and B) = 0.20 and P(A|B) = 0.40, what must the P(B) = ?
a. 0.1
b. 0.2
c. 0.4
d. 0.5
Answer:
The value of P(B) = 0.5
Step-by-step explanation:
Given:
Value of P(A and B) = 0.20
Value of P(A|B) = 0.40
Find:
The value of P(B)
Computation:
P(A and B) = P(A|B) x P(B)
By putting value of P(A and B) and P(A|B)
⇒ 0.20 = 0.40 x P(B)
⇒ The value of P(B) = 0.20 / 0.40
⇒ The value of P(B) = 20 / 40
⇒ The value of P(B) = 1 / 2
The value of P(B) = 0.5
