Answer:
B, 248
Step-by-step explanation:
Out of 45 students in calc and 21 in stats, 14 are repeatedly counted. We can subtract 14 from one group so that this number does not overlap. For example, let us take the calc group:
45-14= 31
31+21 =52 students taking either calc or stats, NOT OVERLAPPED
Everyone else is not taking calc or stats, so 300-52= 248, or B

which expression is equal to 3/4 [8x + 16]
a. 3x + y
b. 3x + 6
c. 4x + 13
d 6x + 12
e. 9x - 2
Answer:
Considering the expression as
[tex]\dfrac{3}{4} \cdot [8x+16][/tex]
We have
[tex]\dfrac{3}{4} \cdot [8x+16] = \dfrac{3}{4} \cdot 8x + \dfrac{3}{4} \cdot 16 = \boxed{6x + 12}[/tex]

Step 1: Define
-2/7w = 8
Step 2: Solve for w
[Division Property of Equality] Divide both sides by -2/7: w = -28Step 3: Check
Plug in w into the original equation to verify it's a solution.
Substitute in w: -2/7(-28) = 8Multiply: 8 = 8Here we see that 8 does indeed equal 8.
∴ w = -28 is the solution to the equation.

Write down in terms of n, an expression for the nth term
of the following sequences:
a) 12 10 8 6 4
b) 25 20 15 20 5
Answer:
a) aₙ = 12 + (n - 1)*(-2)
b) aₙ = 25 + (n - 1)*(-5)
Step-by-step explanation:
These are arithmetic sequeces.
Usually, the n-th term of an arithmetic sequence can be written as
aₙ = aₙ₋₁ + d
or
aₙ = a₁ + (n - 1)*d
where d is the difference between any two consecutive terms.
a) we have the sequence:
12 10 8 6 4
First, we can take the difference between any two consecutive terms to find the value of d (we should check with different pairs, and see if the value of d is always the same):
d = 10 - 12 = -2
d = 8 - 10 = -2
etc.
And the term a₁ is the first term of the sequence, in this case is 12.
Then the n-th term of this sequence can be written as:
aₙ = 12 + (n - 1)*(-2)
b) 25 20 15 20 5
Same as before, first we find the value of d:
d = 20 - 25 = -5
d = 15 - 20 = -5
etc...
We can see that d is equal to -5
and in this case, the first term is 25, then a₁ = 25
Then the n-th term is:
aₙ = 25 + (n - 1)*(-5)

Investigating Hollywood Movies
In the following exercise, we use data from HollywoodMovies. The dataset includes information on all movies to come out of Hollywood between 2007 and 2013. Do Audience Ratings Differ Based on the Genre of the Movie
The dataset Hollywood Movies includes a quantitative variable on the AudienceScore of the movie as well as a categorical variable classifying each movie by its Genre. The computer output below gives summary statistics for audience ratings based on genre for movies made in 2011, using four of the possible genres.
Variable Genre N Mean StDev Minimum Q1 Median Q3 Maximum
AudienceScore Action 32 58.63 18.39 32.00 44.50 51.00 78.00 93.00
Comedy 27 59.11 15.68 31.00 48.00 58.00 71.00 93.00
Drama 21 72.10 14.55 46.00 59.00 72.00 84.50 91.00
Horror 17 48.65 15.88 25.00 34.00 52.00 60.50 78.00
A) Which genre has the highest mean audience score?
B) Calculate the difference in mean score between comedies and horror movies, and give notation with your answer, using Ic for the mean comedy score and Iy for the mean horror score.
C) In which genre is the lowest score, and what is that score? In which genre is the highest score, and what is that score?
Answer:
a. Genre with highest mean is drama. Mean is 72.10
B. 10.46 is difference between means of comedy and horror
C. Horror has the lowest minimum value at 25.00
Action and comedy both have the highest maximum value at 93.00
Step-by-step explanation:
First create a table with the data provided like I did in the attachment. It would give a clearer picture of what your answers should be.
1. Which genre has the highest mean score?
From the table, we have the means as:
Action = 58.63
Comedy = 59.11
Drama = 72.10
Horror = 48.65
The genre with the highest score is drama at 72.10
2. Difference in mean score between comedy and horror
Mean of comedy = lc = 59.11
Mean of horror = ly = 48.65
Difference = lc-ly
= 59.11 - 48.65
= 10.46
3. The genre with lowest score is the genre with the lowest minimum value. This genre is horror and the lowest minimum is 25.00
The genre with highest minimum value is that whose maximum value is the highest out of all the genres. Both action and comedy have the highest maximum value at 93.00

On which number line do the points represent negative seven and one over two and +1?
i says did u guys know pls helpme!!!!!!!!!!!
Answer:
A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers.

Find the value of the function for θ.
sin(45°) = ?
A) 1/2
B) √2/2
C) √3/2
Answer:
B) radical2/2
Step-by-step explanation:
To find the answer, you can A., either type this in a calculator, or B., use the unit circle.
When we observe the unit circle, we can see that the 45* angle is in Quadrant 1, and that the matching radian is pi/4, and the corresponding coordinates are (radical2/2, radical2/2).
So, sin(45*) is B) radical2/2.
Note that sin(θ) means the y-value of the angle's coordinates, cos(θ) normally means the x-value of the angle's coordinates..

d. a firm hand-shake between all those involved in the contract
C.
Please select the best answer from the choices provided
Answer:
B
Step-by-step explanation:
Because the the contract will be in verbal form. no matter if it is videotaped or recorded or both a "videoed verbal contract" not just written. so like paper thst is notarized or not this is still the same bc the the same rules apply the contract is still valid. the rest of the options are more like what they call gentlemens agreements which would be the handshake type of thing. and no matter what any agreement someone has to witness the transaction or contract. so definitely the answer is B

Find the angles in both isosceles triangles.
Let's start with RXWGC first, they mentioned R was 96°, an isosceles triangle also is an triangle which two of the angles in the triangle are the same and one is different.
180 - 96 = 84° (The degree of two other angles)
84 ÷ 2 = 42° (The degree of each angle of the two same angles which is W and C)
After that, find the angles of the other isosceles triangle which is ELWG.
As mentioned that E is 40°, do the same as what was done in RXWGC.
180 - 40 = 140° (The degree of two other angles)
140 ÷ 2 = 70° - (The degree of each angle of the two same angles which is W and C)
Since you have found the degree for X and G...
180 - 42 - 70 = 68° (Degree of X in the small isosceles triangle)

The rectangle below has an area of 30k3 + 6k2.
The width of the rectangle is equal to the greatest common monomial factor of 30k3 and 6k2.
What is the length and width of the rectangle?
Answer:
Width = 6k²
Length = 5k+1
Step-by-step explanation:
Given the area of a rectangle expressed as
A = 30k³ + 6k²
Get the greatest common factor
30k³ = (2 * 3 * k²) * k * 5
6k² = (2 * 3 * k²)
The common factor is the value in bracket i.e 2 * 3 * k² = 6k²
Width of the rectangle = 6k²
Get the length
A = LW
L = A/W
L = 30k³ + 6k²/6k²
L = 6k²(5k+1)/6k²
L = 5k + 1
Hence the length L = 5k+1
A bike accelerates at 10 m/s2 when a force of 50N is applied. What is the mass of the bike? Group of answer choices
Answer: 5kg
Step-by-step explanation:
The mass of the bike if it accelerates at 10 m/s2 when a force of 50N is applied is 5kg
According to Newton's second law of motion,
Force = mass * acceleration
F = ma
Given the folliowing parameters:
Force = 50N
acceleration = 10m/s²
Get the mass:
mass = F/a
mass = 50/10
mass = 5kg
Hence the mass of the bike if it accelerates at 10 m/s2 when a force of 50N is applied is 5kg.
