Answer:
20
Step-by-step explanation:
which side is x ? the Hypotenuse - the side opposite of the 90 degree angle ? or is it one side touching the 90 degree angle ?
that is important. we need to know which side is the Hypotenuse to make the right calculations.
if I assume x is the Hypotenuse, then the calculation follows Pythagoras like this
x² = 12² + 16² = 144 + 256 = 400
x = sqrt(400) = 20
but just in case, if x is a side touching the 90 degrees angle, then the would look like this (depending on which of the other sides is the Hypotenuse)
either
12² = 16² + x²
144 = 256 + x²
-112 = x²
that did not work. a square root of a negative number did not work for actual distances.
or
16² = 12² + x²
256 = 144 + x²
112 = x²
x = sqrt(112) = 10.58

1. Triangle QRS has a perimeter of 55. If RT bisects angle R, what is the length of QT?
a. 10
b. 12
c. 15
d. 18
Answer:
[tex]QT = 10[/tex]
Step-by-step explanation:
Given
[tex]Perimeter = 55[/tex]
See attachment for triangle
The perimeter is calculated as:
[tex]Perimeter = QR + RS + QS[/tex]
This gives:
[tex]55 = 3x + 18 + 2x +12[/tex]
Collect like terms
[tex]3x + 2x = 55 - 18 - 12[/tex]
[tex]5x = 25[/tex]
[tex]x = 5[/tex]
From the attachment:
[tex]QT = 2x[/tex]
[tex]QT = 2 * 5[/tex]
[tex]QT = 10[/tex]
Triangle QRS has a perimeter of 55. If RT bisects angle R, then the length of QT is 10 and this can be determined by using the formula of the perimeter of a triangle.
Given :
Triangle QRS has a perimeter of 55.RT bisects angle R.QS = 2x +12QR = 3xRS = 18The perimeter of the triangle QRS is given by:
Perimeter = QR + RS + QS
55 = QR + RS + QS
Now, put the values of sides QR, RS, and QS in the above equation.
55 = 3x + 18 + 2x + 12
55 = 5x + 30
25 = 5x
x = 5
Now, the length of the QT is given by:
QT = 2x
QT = 10

There are many regulations for catching lobsters off the coast of New England including required permits, allowable gear, and size prohibitions. The Massachusetts Division of Marine Fisheries requires a minimum carapace length measured from a rear eye socket to the center line of the body shell. For a particular local municipality, any lobster measuring less than 3.37 inches must be returned to the ocean. The mean carapace length of the lobsters is 4.01 inches with a standard deviation of 2.13 inches. A random sample of 60 lobsters is obtained.
Required:
What is the probability that the sample mean carapace length is more than 4.25 inches?
Answer:
Probability that the sample mean carapace length is more than 4.25 inches = 0.9993
Step-by-step explanation:
Given - There are many regulations for catching lobsters off the coast
of New England including required permits, allowable gear, and
size prohibitions. The Massachusetts Division of Marine Fisheries
requires a minimum carapace length measured from a rear eye
socket to the center line of the body shell. For a particular local
municipality, any lobster measuring less than 3.37 inches must
be returned to the ocean. The mean carapace length of the
lobsters is 4.01 inches with a standard deviation of 2.13 inches.
A random sample of 60 lobsters is obtained.
To find - What is the probability that the sample mean carapace length
is more than 4.25 inches?
Proof -
Given that, μ = 4.01, σ = 2.13 , n = 60
Now,
μₓ⁻ = σ / √n
= [tex]\frac{2.13}{\sqrt{60} }[/tex]
= [tex]\frac{2.13}{7.746}[/tex] = 0.275
⇒μₓ⁻ = 0.275
Now,
P(X⁻ > 3.37) = 1 - P( X⁻ < 3.37)
= 1 - P(z < [tex]\frac{3.37 - 4.25}{0.275}[/tex] )
= 1 - P( z < -3.2 )
= 1 - 0.0007
= 0.9993
⇒P(X⁻ > 3.37) = 0.9993
∴ we get
Probability that the sample mean carapace length is more than 4.25 inches = 0.9993
Consider the expression

Mr. Wilson is giving his students a vocabulary test tomorrow over all the terms they have learned from this semester. Today, he wants to determine how prepared the students are for the test. So, he writes each term on a note card and puts all the note cards in a paper bag. Then, he asks each student to come to his desk, select five note cards out of the bag, define those five terms, and then put the note cards back in the bag. He records the number of terms each student is correctly able to define.
1. What is the population in this situation? What is the sample? Use complete sentences in your answer.
2. Do you think the data from the sample Mr. Wilson is collecting is representative of the population? Explain your reasoning using complete sentences.

if cot theta = -2, find the value of cot theta + cot (theta -pi) + cot (theta-2pi)
Given:
[tex]\cot \theta = -2[/tex]
To find:
The value of [tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)[/tex].
Solution:
We know that,
[tex]\cot (\theta -n\pi)=\cot \theta[/tex] ...(i)
Where n is an integer.
We have,
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)[/tex]
Using (i), it can be written as
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=\cot \theta +\cot \theta +\cot \theta [/tex]
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3\cot \theta[/tex]
It is given that [tex]\cot \theta = -2[/tex].
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3(-2)[/tex]
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=-6[/tex]
Therefore, the value of the given function expression is [tex]-6[/tex].

Hello There!
Once again we need to isolate the variable using inverse operations
to get rid of the -8.2 we add 8.2 to each side
-8.2+8.2 cancels out
-9.7+8.2=-1.5
now we have
-1.2z>-1.5
now we wan to get rid of the -1.2
to do so we want to divide each side by -1.2
[tex]\frac{-1.2z}{-1.2} =z\\\\\frac{-1.5}{-1.2} =1.25[/tex]
Remember we have to flip the inequality sign because we're dividing by a negative number
we're left with

Point B is reflected over the y-axis to create the point B'. Then, points B, B' and C are connected to form a triangle. What is the area of the triangle formed? 48 square units 14 square units 28 square units 24 square units
Answer:
24 square units
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation translation and dilation.
If a point O(x, y) is reflected along the y axis, the new location would be O(-x, y).
The coordinate of the triangle is B(3, 5), C(3, -3). Therefore since B is reflected along y axis to form B'. Hence, B' = (-3, 5)
[tex]|BC|=\sqrt{(3-3)^2+(5-(-3))^2}=8\ units \\\\|CB'|=\sqrt{(-3-3)^2+(5-5)^2}=6\ units \\\\Area\ of\ triangle\ BCB'=\frac{1}{2}* |BC|*|BB'|=0.5*8*6\\\\Area\ of\ triangle\ BCB'=24\ units[/tex]
