triangle ABC has side lengths 8 inches, 17 inches, and 15 inches. Sofia uses the following steps to conclude that triangle ABC is not a right triangle.
[tex]a^{2} +b^{2} =c^{2} \\8^{2} +17^{2} =15^{2} \\64+289=225\\353\neq 225[/tex]
What mistake did Sofia make?
A Sofia made a calculation error.
B Sofia used the length of one of the legs as c when she should have used the length of the longest side as c.
C Sofia does not know if triangle ABC is a right triangle, so she cannot use the Pythagorean Theorem or its converse.
D Sofia’s conclusion is incorrect. When the sides of a triangle do not satisfy a2+b2=c2, you cannot conclude that the triangle is a right triangle.
Answer: Its b.
Step-by-step explanation: The hypothenuse is the biggest number and the leg is the two shortest numbers.

3. PLZZZZ HELP MEEE!.!.!
Answer:
60in²
Step-by-step explanation:
Since lateral surface area means all the shapes except the base, we will ignore the square in the middle.
A=1/2(b*h)
A=1/2(10*3)
A=15in²
Now we will multiply the area by 4 or the number of other shapes besides the base.

Pam's eye–level height is 256 feet above sea level and Adam's eye–level height is 400 feet above sea level. What expression shows how much farther Adam can see to the horizon? In simplest terms, Adam can see a√b feet farther than Pam.
Answer:
B
A=2
B=6
Step-by-step explanation:
The expression that shows how much farther Adam can see to the horizon should be considered as the d = 400 - 256 and d = 256 - 400.
Calculation of the expression:Since
Pam's eye–level height is 256 feet above sea level and Adam's eye–level height is 400 feet above sea level.
So here the expression be like The expression that shows how much farther Adam can see to the horizon should be considered as the d = 400 - 256 and d = 256 - 400.

You flip a coin 30 times, about how many times would you expect to tails to appear?
Answer:
15 heads out of 30
Step-by-step explanation:
The total number of possible sequences of coin flips can be determined by raising the number of outcomes, which is 2 for any coin (heads or tails), to the power of the number of times the coin is flipped, given by the question as 30. Therefore, 230 is the total number of different sequences for 30 coin flips.
We can use combinatorial math to find the number of sequences with exactly 15 heads, which is 30 choose 15 or (3015) . The probability we are looking for will be the number of sequences with 15 heads divided by the total possible sequences.
Now we can express the whole probability in math notation, and calculate an answer (rounded to 4 decimal places):
(3015)230=1551175201073741824≈0.1445≈14.45%
15 heads out of 30 is the most likely outcome when flipping 30 coins, if you run the same calculation with 14 or 16 heads you will get two equal, but smaller probabilities, same with 13 and 17 heads, and so on. If you graphed all of the outcomes, you will find it follows a normal distribution, or Bell curve, with the outcome of 15 heads, located at the peak.
If the coin is tossed 30 times then the expected value of the tails to appear is 15 which means tails will appear 15 times.
How to find that a given condition can be modeled by binomial distribution?Binomial distributions consist of n independent Bernoulli trials.
Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as
[tex]X \sim B(n,p)[/tex]
The probability that out of n trials, there'd be x successes is given by
[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]
The expected value and variance of X are:
[tex]E(X) = np\\[/tex]
You flip a coin 30 times then the expected value will be
The probability of getting tails is 0.5 then the expected value will be
[tex]E(X) = 0.5 \times 30\\\\E(X) = 15\\[/tex]

If X = 2 units, Y = 9 units, and Z = 6 units, then what is the volume of the rectangular prism shown above?
Answer:
108 cubic units
Step-by-step explanation:
If X = 2 units, Y = 9 units, and Z = 6 units, then what is the volume of the rectangular prism shown above?
Volume of a rectangular prism XYZ = Length × Width × Height
= 2 unit × 9 unit × 6 unit
= 108 cubic units

a. Identify the slope and y-intercept of the graph of each equation.
b. Based on your answer for part (a), are the graphs of the two lines intersecting lines, the
same line, or parallel lines? Explain your reasoning.
Answer:
see below
Step-by-step explanation:
a.
first equation: slope = 2, y intercept = (0,4)
second equation: slope = -1, y intercept = (0,5)
b.
They are intersecting lines. They don't have the same slope so they aren't parallel and they obviously aren't the same equation so they aren't the same line.

the length of a rectangle is 7 cm more than its width and the area is 30 cm find the length, width and the perimeter
Answer:
Step-by-step explanation:
let width=x
length=x+7
x(x+7)=30
x²+7x-30=0
x²+10x-3x-30=0
x(x+10)-3(x+10)=0
(x+10)(x-3)=0
either x=-10 (rejected being negative)
or x=3
width=3 cm
length=3+7=10 cm
Perimeter=2(10+3)=2×13=26 cm
