Answer:
The overall score is 75.6
Letter grade is C
Step-by-step explanation:
The question has missing details (See comment section for complete question).
From the complete question, we have:
Proportion:
[tex]Midterm = 15\%[/tex]
[tex]Project = 25\%[/tex]
[tex]Assignment = 40\%[/tex]
[tex]Exam = 20\%[/tex]
Scores
[tex]Midterm = 66[/tex]
[tex]Project = 90[/tex]
[tex]Assignment = 75[/tex]
[tex]Exam = 66[/tex]
Solving (a): The overall score
To do this, we simply calculate the mean of the given data.
The mean is calculated by multiplying each proportion by the scores..
So, we have:
[tex]Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66[/tex]
[tex]Overall = 9.9 + 22.5 + 30 + 13.2[/tex]
[tex]Overall = 75.6[/tex]
Solving (b): The letter grade
From the question, we have:
[tex]A: Mean \ge 90[/tex]
[tex]B: 80 \le Mean < 90[/tex]
[tex]C: 70 \le Mean < 80[/tex]
The overall score falls in the following category:
[tex]C: 70 \le Mean < 80[/tex]
Because:
[tex]70 \le 75.6 < 80[/tex]
Hence, the letter grade is C

__% of 4 is 7
Please help
Answer:
175%
Step-by-step explanation:
1. To find how much a percent of a number is, we'd just have to multiply the percent by the number. However, in this case, we're missing the percentage.
2. To find that percentage, we can write an equation of [tex]\frac{x}{100} * 4 = 7[/tex] because "of 4" means to multiply by 4, and "is 7" means that the product is 7.
3. Now, let's solve our equation.
[tex]\frac{x}{100} * 4 = 7[/tex]Step 1: Simplify both sides of the equation.
[tex]\frac{4}{100}x = 7[/tex] [tex]\frac{1}{25}x=7[/tex]Step 2: Multiply both sides by 25.
[tex]\frac{1}{25}x * 25 = 7 * 25[/tex] [tex]x = 175[/tex]Step 3: Check to see if solution is correct.
[tex]\frac{175}{100} * 4 = 7[/tex] [tex]\frac{700}{100} = 7[/tex] [tex]7 = 7[/tex]Therefore, the answer is 175%.

4x + 6 = 2(2x +3) is an example of what type of equation?
Answer:
Simplifying
4x + -6 = 2(2x + 3)
Reorder the terms:
-6 + 4x = 2(2x + 3)
Reorder the terms:
-6 + 4x = 2(3 + 2x)
-6 + 4x = (3 * 2 + 2x * 2)
-6 + 4x = (6 + 4x)
Add '-4x' to each side of the equation.
-6 + 4x + -4x = 6 + 4x + -4x
Combine like terms: 4x + -4x = 0
-6 + 0 = 6 + 4x + -4x
-6 = 6 + 4x + -4x
Combine like terms: 4x + -4x = 0
-6 = 6 + 0
-6 = 6
Solving
-6 = 6

CAN SOMEONE PLEASE HELP
In the diagram, line l is parallel to line m and is cut by transversal n. The measure of angle one is equal to 3x+6 and angle two measures 6(x−2).
What is the measure of angle one?
Answer:
24
Step-by-step explanation:
Since the lines L and M are parallel:
Angle 1 and and 2 are alternate and their measurement is equal.
3x + 6 = 6x - 12 (we multiplied 6 with inside the parenthesis)
6 + 12 = 6x - 3x
18 = 3x divide both sides by 3
6 = x to find the angle measure replace x with 6
3x + 6 is 3*6 + 6 = 24

Answer:
The solution is A. (-2,7) and C. (3,2)
Step-by-step explanation:
x+y = 5 ............(1)
x²+y = 11 ............(2)
_________________________
y = 5-x
x²+(5-x) = 11
x²+5-x-11 = 0
x²-x-6 = 0
x²+2x-3x-6 = 0
(factor statement)
x(x+2)-3(x+2) = 0
(x+2) (x-3) = 0
x+2=0 x-3 =0
x = -2 x = 3
(x1 = -2, x2 = 3)
_________________________
y = 5-x
y = 5-(-2) ............(1)
= 7
y = 5-3 ............(2)
= 2
(y1 = 7, y2 = 2)
_________________________
(x1,y1) & (x2,y2)
(-2,7) & (3,2)
So, A. (-2,7) and C. (3,2) correct

Answer:
1, 3, 5
Step-by-step explanation:
let the 3 consecutive odd numbers be n , n + 2 , n + 4 , then
5(n + 2) = 2(n + n + 4) + 3 ( 5 times 2nd = twice sum of 1st and 3rd + 3 )
5n + 10 = 2(2n + 4) + 3
5n + 10 = 4n + 8 + 3
5n + 10 = 4n + 11 ( subtract 4n from both sides )
n + 10 = 11 ( subtract 10 from both sides )
n = 1
n + 2 = 1 + 2 = 3
n + 4 = 1 + 4 = 5
The 3 consecutive odd numbers are 1, 3, 5
Step-by-step explanation:
let the three consecutive odd number be x + 1 , x + 3 , x + 5
a/q
5 times the middle number = 5(x + 3) is
3 more than twice the sum of 1st and 3rd number = 3 + 2(x+1 + x + 5 )
so,
= 5 ( x + 3 ) = 3 + 2 ( x + 1 + x + 5 )
= 5x + 15 = 3 + 4x + 12
= 5x + 15 = 4x + 15
= -4x + 5x = 15 - 15 = 0
= x = 0
so, the 3 consecutive odd numbers are,
x + 1 = 1
x + 3 = 3
x + 5 = 5
and also a/q
5 times the middle number = 5×3 = 15
is equal to 3 more than twice the sum of 1st and 3rd number = 3 + 2(1+5) = 12 + 3 = 15
LHS = RHS
hope this answer helps you dear...take care and may u have a great day ahead!

F(x) =2x-1 what is the value of f(x) when x = -1
Answer:
f(x) = -3 when x = -1
Step-by-step explanation:
Let's go through this!
So our equation is f(x) = 2x - 1
we are asked for the value of f(x) when x = -1
Let's consider this, the f(x) value is the y value
and the x value in f(x) is the x value
So when x = -1
what is the y value?
we can use the equation to subsitute -1 into x and solve for f(x)
f(x) = 2(-1)-1
f(x) = -3
Our answer is -3
