Danny flips four well-balanced coins. What are the odds that two of the coins will land ‘heads’ up?
Answer:
0.375 = 37.5% probability that two of the coins will land ‘heads’ up
Step-by-step explanation:
For each coin, there are only two possible outcomes. Either it lands heads, or it lands tails. The probability of a coin landing heads is independent of any other coin. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Four well-balanced coins.
This means that [tex]n = 4, p = 0.5[/tex]
What are the odds that two of the coins will land ‘heads’ up?
This is P(X = 2).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{4,2}.(0.5)^{2}.(0.5)^{2} = 0.375[/tex]
0.375 = 37.5% probability that two of the coins will land ‘heads’ up

HELP! WILL GIVE BRANLIEST!!
Answer:
X=8
z=80
Step-by-step explanation:
Okay to find X you gotta find the other angle.
The other angle is 100 which is also vertical To (6x+52)
Vertical angles are equal or congruent so you cna make an eqaution to equal it
6x+52=100
Solve it like a normal equation
x=8
To find Z you gotta realize that 4 angles equal 360 degrees.
We knwo the two vertical angles, 100 and 100. Z is vertical to no name angle so its equal so it can also be Z. Z+Z=2z
Now If you add em all up you should get 360
2z+100+100=360
2z+200=360
Solve from here
z=80

first blank is "Permutation", i dont know what the second blank is but its not 17550
Step-by-step explanation:
This is an example of a permutation. There are 421,200 possible arrangements of first through fourth place winners.
What is permutation?"A permutation is an arrangement of objects in a definite order. The members or elements of sets are arranged here in a sequence or linear order."
We need to arrange 27 swimmers for 4 positions
Hence, the numbers are 27P4
= [tex]\frac{27!}{(27-4)!}[/tex]
[tex]=\frac{27.26.25.24.23!}{23!}[/tex]
[tex]=421,200[/tex]
Hence, the given situation is an example of permutation with 421,200 possible arrangements.

Estimate the perimeter and the area of the shaded figure
Show how you got your answer
Answer:
Perimeter = 16 feet
Total Surface Area = 24 sq ft.
Step-by-step explanation:
Let's assume that each square is equal to 1 foot. Using this we can estimate the perimeter and area as the following. For perimeter, we simply add all the squares distances surrounding the shaded object.
Perimeter = 16 feet (4 feet for the top and bottom and 2 feet every diagonal)
For the area, we need to calculate the area of the square in the middle and then the area of the two triangles.
Square = L * W
Square = 4 * 4
Square = 16 sq ft
Triangle = 0.5 * Base * Height
Triangle = 0.5 * 4 * 2
Triangle = 4 sq ft
Both triangles = 4 sq ft * 2 = 8 sq ft.
Now we add both area totals:
Total Surface Area = 16 + 8
Total Surface Area = 24 sq ft.

Answer:
t=[tex]\sqrt{\frac{38}{g} }[/tex]
Step-by-step explanation:
19=(1/2)gt²
(multiply both sides by 2)
38=gt²
(divide both sides by g)
t²=(38/g)
(square root both sides)
t=[tex]\sqrt{\frac{38}{g} }[/tex]
A container is in a shape of a right circular cylinder standing on its base. If 100 cubic centimeters of water is poured into the container the height of the water is 8 centimeters. What is the height of the water if only 75 cubic centimeters is poured into the container?
A) 2.1 cm
B) 3.8 cm
C) 6.0 cm
D) 6.9 cm
E) 10.7 cm
And why???
Answer:
Step-by-step explanation:
The shape of the container isn’t changing here, so the height of the water will be proportional to the volume. 75 cm^3 is ¾ of 100 cm^3, so the water will rise ¾ as high.
¾ of 8 cm is 6 cm.

The area of a composite shape is the sum of the areas of its individual shapes
The area of the composite shape is 215.20 square feet.
From the figures, we have the following shapes
A semicircle with a diameter of 22 ftA semicircle with a diameter of 8 ft (i.e. 30ft - 22ft)The area (A) of a semicircle is:
[tex]\mathbf{A = \frac{\pi d^2}{8}}[/tex]
So, the area of the composite shape is:
[tex]\mathbf{A = \frac{\pi (d_1^2 + d_2^2)}{8}}[/tex]
This gives
[tex]\mathbf{A = \frac{\pi (22^2 + 8^2)}{8}}[/tex]
[tex]\mathbf{A = \frac{\pi (548)}{8}}[/tex]
[tex]\mathbf{A = 68.5\pi}[/tex]
