Step-by-step explanation:
Determine the measure of ∠Q, rounded to the nearest tenth of a degree.
Question 9 options:
A)
22.8°
B)
73.5°
C)
36.1°
D)
66.0°
In the given triangle the measure of ∠Q is (B) 73.5°.
What is a triangle?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.So, let's use the Sine rule in the calculation as follows:
q/sin q = r/sin r15/sin q = 12/sin 50.1 (Cross multiply)12 × sin q = 15 × sin 50.1 (divide both sides by 12)sin q = 15 sin 50.1/12q = sin⁻¹(15 sin 50.1/12) ≈ 73.5° (Rounded off)Therefore, in the given triangle the measure of ∠Q is (B) 73.5°.

Step-by-step explanation:
The base of a triangle is....
Answer:
[tex]a=49[/tex]
Step-by-step explanation:
You would solve this the same way you would with any other triangle problem. You will plug in for the base and the height in this formula [tex]a=\frac{1}{2}bh[/tex].
[tex]a=\frac{1}{2}bh\\a=\frac{1}{2}(\sqrt{343})(\sqrt{28})[/tex]
Now we will multiply the two radicands.
[tex]a=\frac{1}{2}\sqrt{9604}[/tex]
For this we will split the 9604 into 49 and 196.
[tex]a=\frac{1}{2}\sqrt{49}\sqrt{196}[/tex]
Now we just take the square roots of those two and since they're perfect squares they'll be whole numbers.
[tex]a=\frac{1}{2}(7)(14)[/tex]
Next we just multiply everything together.
[tex]a=49[/tex]
Simplify. 1+i/1-I + 1/ 1 + i. if i^2 = -1
I guess you mean
(1 + i ) / (1 - i ) + 1 / (1 + i )
in which case, notice that the denominator of both fractions are conjugates of one another. Combine the fractions by multiplying either fraction by the appropriate conjugate:
[(1 + i ) / (1 - i ) • (1 + i ) / (1 + i )]+ [1 / (1 + i ) • (1 - i ) / (1 - i )]
In either denominator, we have a difference of squares:
(1 + i ) (1 - i ) = 1² + i - i - i ² = 1² - i ² = 1 + 1 = 2
→ (1 + i )² / 2 + (1 - i ) / 2
→ ((1 + i )² + (1 - i )) / 2
Expand the numerator:
(1 + i )² + (1 - i ) = (1² + 2i + i ²) + 1 - i = 1 + 2 - 1 + 1 - i = 3 - i
and so
(1 + i ) / (1 - i ) + 1 / (1 + i ) = (3 - i ) / 2

A certain statistic will be used as an unbiased estimator of a parameter. Let R represent the sampling distribution of the estimator for samples of size 35, and let S represent the sampling distribution of the estimator for samples of size 15. Which of the following must be true about R and S?
a. The expected values of R and S will be equal, and the variability of R will be less than the variability of S.
b. The expected values of R and S will be equal, and the variability of R will be equal to the variability of S.
c. The expected values of R and S will be equal, and the variability of R will be greater than the variability of S.
d. The expected value of R will be greater than the expected value of S, and the variability of R will be greater than the variability of S.
e. The expected value of R will be greater than the expected value of S, and the variability of R will be less than the variability of S.
Answer:
c. The expected values of R and S will be equal, and the variability of R will be greater than the variability of S.
Step-by-step explanation:
This is Central Limit Theorem concept in which independent variables are added and form a normal distribution. The random sample of n sample size is selected which calculates normally distributed mean and variance. The expected value of samples distributor will be higher than the sample distribution.
Using the Central Limit Theorem, it is found that the correct option is:
a. The expected values of R and S will be equal, and the variability of R will be less than the variability of S.Central Limit Theorem The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation, measuring variability, of [tex]s = \frac{\sigma}{\sqrt{n}}[/tex]. Hence, a higher sample size leads to less variability.In this problem:
The samples are taken from the same population, hence they have the same expected value.Due to the higher sample size, R has less variability.Hence, option A is correct.To learn more about the Central Limit Theorem, you can take a look at https://brainly.com/question/25581475

a triangle has two angles with measures of 40 degrees and 60 degrees. What is the measure of the third angle?
Answer:
80 degrees
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees.
Let the third angle be x.
Add all the quantities and subtract the answer from 180.
So: 180= 40+60+x
180-100=x
80=x

N is a multiple of 5
A = N + 1
B = N – 1
Prove, using algebra, that A2 – B2 is always a multiple of 20
Answer:
Proved
[tex]A^2 - B^2 = 20, 40,60,80...[/tex]
Step-by-step explanation:
Given
[tex]A = N + 1[/tex]
[tex]B = N - 1[/tex]
Required
Prove that [tex]A\² - B\²[/tex] is a multiple of 20
First, we need to evaluate [tex]A\² - B\²[/tex]
Start by applying difference of two squares
[tex]A\² - B\² = (A + B)(A - B)[/tex]
Substitute values for A and B
[tex]A\² - B\²= (N + 1 + N - 1)(N + 1 -(N-1))[/tex]
[tex]A\² - B\² = (N + 1 + N - 1)(N + 1 - N + 1)[/tex]
Collect Like Terms
[tex]A\² - B\² = (N + N+ 1 - 1)(N - N + 1+ 1)[/tex]
[tex]A\² - B\² = (2N)(2)[/tex]
[tex]A\² - B\² = 2N*2[/tex]
[tex]A\² - B\² = 4N[/tex]
Since, N is a multiple of 5, then the possible values of N are:
[tex]N = 5, 10, 15, 20...[/tex]
For each of these values, the possible values of [tex]A^2 - B^2[/tex] are
[tex]A^2 - B^2 = 4N: 4 * 5, 4*10,4*15,4*20...[/tex]
[tex]A^2 - B^2 = 20, 40,60,80...[/tex]
The above shows that [tex]A^2 - B^2[/tex] is a multiple of 20

A linear function passes through (-2, 12) and (4,0). What is the slope of the function?
Answer:
-2
Step-by-step explanation:
I actually just did functions in math at the end of last semester I offer you my condolences dude
The slope of the function that passes through two points (-2, 12) and (4,0) is -2
Slope of the function
Slope of the function is calculated by find the rate of change of y over rate of change of x.
The formula to fidn out the slope is
[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]
The function passes through two points (-2,12) and (4,0)
substitute the points and find out the slope of the fuction
(x1,y1) is (-2,12)
(x2,y2) is (4,0)
Substitute the values
[tex]slope =\frac{0-12}{4+2}=\frac{-12}{6} =-2[/tex]
The slope of the function that passes through two points (-2, 12) and (4,0) is -2

8
CLEAR ALL
Answer:
t = 8w + w/2
Step-by-step explanation:
Given that :
Weight of bird = w
Amount of water consumed = 8*w = 8w
Amount of food ate = 0.5*w = 1/2w
Hence, the combined weight of water and food (t) consumed by the humming bird :
t = amount of water consumed + amount of food ate
t = 8w + w/2
