A cereal box has a height of 10 inches, a length of 8 inches, and a width of 2 inches. What is the surface area of the cereal box?
Answer:
232 in^2
Step-by-step explanation:
Using the formula for surface area A=2(wl+hl+hw)
A=2(16+80+20)
A=232
The surface area of the cereal box is 232 square inches
What is the surface area of cuboid?The surface area of a cuboid is the total area of all its surfaces. Since a cuboid is a three-dimensional solid shape, the value of its surface area depends on the dimensions of its length, width, and height. The change in any of the dimensions of a cuboid changes the value of the surface area of a cuboid. The surface area of a cuboid is expressed in square units.
Total Surface Area of Cuboid
= 2 (length*width + width*height + length*height)
According to the question
A cereal box has a height = 10 inches
A cereal box has a length = 8 inches
A cereal box has a width = 2 inches
Now ,
Applying the formula of Total Surface Area of Cuboid as cereal box is also a cuboid
Total Surface Area of Cuboid
= 2 (length*width + width*height + length*height)
substituting the values
Total Surface Area of Cuboid
= 2 (8*2 + 2*10 + 8*10)
= 2 (16 + 20 + 80)
= 2(116)
= 232 square inches
Hence, the surface area of the cereal box is 232 square inches

A fair coin is tossed 14 times. What is the probability of obtaining exactly 1 head? (Enter your answer as a reduced fraction or a decimal rounded to 4 places.)
Answer:
0.0009 probability of obtaining exactly 1 head
Step-by-step explanation:
For each toss, there are only two possible outcomes. Either it is a head, or it is not. The probability of a toss being a head is independent of any other toss. This means that we use the binomial probability distribution 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.
A fair coin is tossed 14 times.
Fair coin means that it is equally as likely to be heads or tails, so [tex]p = 0.5[/tex]
14 times means that [tex]n = 14[/tex]
What is the probability of obtaining exactly 1 head?
This is P(X = 1).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{14,1}.(0.5)^{1}.(0.5)^{13} = 0.0009[/tex]
0.0009 probability of obtaining exactly 1 head
A park is in the shape of a rectangle 8 miles long and 6 miles wide. What is the diagonal length across the park?
Answer:
The diagonal length is 10 miles.
Step-by-step explanation:
This is the work of the Pythagorean theorem : [tex]a^{2} + b^{2} = c^{2}[/tex]
-------------------------------
[tex]8^2 + 6^2 = c^2\\100 = c^2\\10=c[/tex]
Good Luck!!!
Answer:
10 miles
Step-by-step explanation:
pythagoras' Theorem
8^2 + 6^2 = c^2
64 + 36 = 100
c^2 = 100
c = √100
c = 10 miles
Las longitudes que se forman entre los vertices y el centro de un poligono regular son por favor respondan :'c
Answer:
Las longitudes que se forman entre los vértices y el centro de un polígono regular son;
Los radios del círculo circunscrito
Step-by-step explanation:
Cada círculo de radio, 'r', tiene un polígono que se puede inscribir polígono regular que tiene 'n' lados, donde n ≥ 3 y viceversa, todos los polígonos regulares se pueden inscribir (dibujar) en un círculo, que luego se conoce como la circunferencia del polígono
Dado que un polígono regular se puede inscribir en un círculo, de modo que sus vértices descansen sobre la circunferencia del círculo, entonces el centro del polígono es el centro del círculo que lo circunscribe.
Por lo tanto, las longitudes (iguales) que se forman entre los vértices y el centro del polígono regular son el radio del círculo que lo circunscribe..
(50 POINTS) Math Inverse Functions please help
Answer:
See below.
Step-by-step explanation:
An inverse function has the x and y coordinates switched. For example, if a function has point (1, 3), then the inverse function has point (3, 1).
Let's find the ordered pairs of the inverse function. We take all the ordered pairs of the original function:
(1, 3), (7, 4), (8, 6), (9, y)
Now we switch x and y in each ordered pair to come up with the inverse function.
The inverse function has these ordered pairs:
(3, 1), (4, 7), (6, 8), (y, 9)
For a relation to be a function, a value used as an x-coordinate can appear only once.
The last ordered pair is (y, 9). For the inverse relation to be a function, y cannot be 3, 4, or 6.
Answer:
inverse of ordered pair (1,3),(7,4),(8,6)and (9,y)
is (3,1),(4,7),(6,8)and(y,9)
restriction is
y≠3,4&8

Hi!
So to find out the slope, we can use the equation change in y value over change in x value -- or vertical change over horizontal change.
Find two points on the graph that line up exactly on the lines of the graph, like (20, 0) and (12, 0).
Then, take the change in y value (20-0 = 20) and divide it by the change in x value (0 - 12) to get -20/12, or -5/3.

A. The range is 31.
B. The mode is 78
C. The median is 51
D. The mean is 52.
Answer:
D. The mean is 52.
Step-by-step explanation:
In order to find the mean, you add up all of the numbers and then divide that answer by how many numbers there are.
43+50+60+36+47+52+78=416
416/8=52
Answer:
D. The mean is 52.
Step-by-step explanation:
Add all numbers in the set:
36+47+50+50+52+60+78= 416
Now, divide the sum by how many numbers are in the set; in this case, there are 8 numbers so:
416÷ 8= 52

HELP PLEASE!! Identify Structure What linear expression would you need to subtract from (5x+3) to have a difference of −x ?
Answer:
Expression that is to be deducted will be (6x + 3).
Step-by-step explanation:
Let the linear expression that is to be subtracted from the given expression (5x + 3) is (ax + b).
After subtracting (ax + b) from (5x + 3) the remainder is (-x)
(5x + 3) - (ax + b) = -x
(5x - ax) + (3 - b) = -x
(5 - a)x + (3 - b) = -x
By comparing coefficients,
(5 - a) = -1
a = 5 + 1
a = 6
(3 - b) = 0
b = 3
Therefore, expression that is to be deducted from (5x + 3) will be (6x + 3).
