You're making a sandwich at the cafeteria where they have 2 kinds of bread, 2 kinds of cheese, and 3
kinds of meat. How many different sandwiches could you make? Assume multiple kinds of
breads/cheese/meats are not mixed in a sandwich.
Answer:
12 different types of sandwich could be made.
Step-by-step explanation:
Since I am making a sandwich at the cafeteria where they have 2 kinds of bread, 2 kinds of cheese, and 3 kinds of meat, to determine how many different sandwiches could I make the following calculations must be performed:
Bread x cheese x meat = X
2 x 2 x 3 = X
4 x 3 = X
12 = X
Therefore, 12 different types of sandwich could be made.
What is the value of x?
Answer: Value of x is 16

Triangle ABC and ADE are Similar Triangles using Angle-Angle-Angle similarity,
therefore,
\(\frac{AB}{BC}=\frac{AD}{DE}\)
AB=x
BC=8
AD=x+6
DE=11
on substituting value,
\(\frac{x}{8}=\frac{x+6}{11}\)
on cross multiplying,
11x = 8x+48,
subtracting 8x on both sides,
3x = 48,
dividing both sides by 3,
x=16
Therefore, value of x is 16

Shang-Chi is part of Phase 4 of the MCU, which
includes 11 movies in total. The total number of
movies in the first three phases is 23. What is the ratio
of Phase 4 movies to total movies in the MCU so far?
The ratio of Phase 4 movies to total movies in the MCU so far based on the information will be 11:23.
Number of movies in part of Phase 4 of the MCU = 11 movies
The total number of movies in the first three phases = 23.
Therefore, the ratio will be gotten since we know the movies in phase 4 and the total movies so far. This will be:
= 11/23 = 11:23.
In conclusion, the ratio of Phase 4 movies to total movies in the MCU so far will then be 11:23.

A normally distributed data set has a mean of 0 and a standard deviation of 0.5. Which is closest to the percent of values between –1 and 1?
34%
50%
68%
95%
As a result, 68% of the data falls into the range of values between -1 and 1, which is one standard deviation from the mean. The closest estimate of the solution is 68%.
What is equation?A mathematical equation is a formula that connects two claims and uses the equals symbol (=) to denote equivalence. An equation in algebra is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign places a space between the variables 3x + 5 and 14. The relationship between the two sentences that are written on each side of a letter may be understood using a mathematical formula. The symbol and the single variable are frequently the same. as in, 2x - 4 equals 2, for instance.
For a normally distributed data set with a mean of 0 and a standard deviation of 0.5, the proportion of values between -1 and 1 is most closely related to 68%.
Approximately 68% of the data in a normal distribution lies within one standard deviation of the mean, which explains why. One standard deviation below the mean is -0.5, and one standard deviation above the mean is 0.5 since the mean is 0 and the standard deviation is 0.5. As a result, 68% of the data falls into the range of values between -1 and 1, which is one standard deviation from the mean. The closest estimate of the solution is 68%.

an object is dropped from a height of 25 meters at what velocity will it hot the ground
Given data
height (h) = 25 m ,
velocity (v) = ?
we know that,
v²-u² = 2as
initial velocity (u) = 0,
a = g = 9.8 m/s ,
Now the equation becomes,
v² = 2 × g × h
= 2 × 9.8 × 25
v² = 490.5
v = √490.5
v = 22.1 m/s
Therefore answer is C , i.e., 22 m/s

Option B is correct.
Define Pythagoras theorem?The right-angled triangle's three sides are related in line with the Pythagoras theorem, also referred to as the Pythagorean theorem. The hypotenuse of a triangle's other two sides add up to a square, according to the Pythagorean theorem, which states that.
Here in the question,
We have 2 right-angled triangles.
So, base of the large triangle, x
= √ (13² - 12²) + √ (13² - 12²)
= √ 5² + √ 5²
= 5 + 5

Determine the equation of the circle with radius 9 and center ( − 1 , − 8 ).
The equation of the circle with radius 9 and center ( -1,-8 ) is( x + 1 )² + ( y + 8 )² = 81.
What is the equation of the circle?The standard form equation of a circle with center (h, k) and radius r is:
( x - h )² + ( y - k )² = r²
Given that the circle has a center of (-1, -8) and the radius is 9.
Hence; from the standard form of the equation of the circle:
Center ( h , k ) = ( -1, -8 )
h = -1
k = -8
And radius r = 9
Plug these values into the above formula and simplify.
( x - h )² + ( y - k )² = r²
( x - ( -1 ) )² + ( y - ( -8 ) )² = 9²
Simplify
( x + 1 )² + ( y + 8 )² = 81
Therefore, the equation of the circle is ( x + 1 )² + ( y + 8 )² = 81.

Suppose that 45% of students in a college have a smart phone. If you select three students at random, what is the probability that all three have a smart phone? Give your answer as a decimal (to at least 3 places) or fraction
Answer:
\( P(X=3)\)
And we can use the probability mass function and we got:
\(P(X=3)=(3C3)(0.45)^3 (1-0.45)^{3-3}=0.091\)
Then the probability that all three have a smart phone is 0.091
Step-by-step explanation:
Let X the random variable of interest "number of students with smartphone", on this case we now that:
\(X \sim Binom(n=3, p=0452)\)
The probability mass function for the Binomial distribution is given as:
\(P(X)=(nCx)(p)^x (1-p)^{n-x}\)
Where (nCx) means combinatory and it's given by this formula:
\(nCx=\frac{n!}{(n-x)! x!}\)
And we want to find this probability:
\( P(X=3)\)
And we can use the probability mass function and we got:
\(P(X=3)=(3C3)(0.45)^3 (1-0.45)^{3-3}=0.091\)
Then the probability that all three have a smart phone is 0.091
