Answer:
the four scores are 68, 76, 78, and 78.
Step-by-step explanation:
The mean of the four scores is 75.
So, the sum of all the four scores is equal to the product of mean and number of scores. Therefore,
Sum of scores , 'S' = Mean Number of scores.
Now, let one of the middle scores be 'x'.
Since the number of scores is even, the median is half of the sum of the two middle terms.
Median is given as 77 and mode is 78.
So, median is given as:
As 76 is smaller than 78.
So, the 2nd score is 76 and third score is 78.
Since mode is 78, it has to be repeated more than once. So, the fourth score will also be 78.
Now, let the first score be 'y'. Therefore, the sum is given as:
Therefore, the four scores are 68, 76, 78, and 78.

solve y
y=8x-x^2
y=2x
STEP BY STEP SOLUTION PLEASE HELP
Answer:
y=12
Step-by-step explanation:
y=2x ,so 2x=8x-x^2
x^2=8x-2x
x^2=6x
x^2/x=6x/x
x=6
y=2x ,2(6)
y=12

Last
year at a certain high school, there were 60 boys on the honor roll and 130 girls
on the honor roll. This year, the number of boys on the honor roll increased by 5%
and the number of girls on the honor roll increased by 20%. By what percentage did
the total number of students on the honor roll increase? Round your answer to the
nearest tenth (if necessary).
Answer:
15.3%
Step-by-step explanation:
60x.05 = 3 boys
130x.20 = 26 girls
3+26 = 29 students
60+130 = 190 total students
(29/190)*100 = 15.3%

Ms. Sublett's math class is putting three numbers (0.3, 1/4, and 20%) in order from least to greatest. What order should the numbers be from least to greatest?
Answer:
least to greatest
20% , 1/4, 0.3
20% = 1/5 = 0.2
0.3 = 3/10 = 30%
1/4 = 25% = 0.25
-0.1b = 3.8, what is b?
-0.1b = 3.8 ; Get b alone

b = -38

Step-by-step explanation:
We should first simplify the right side, and doing so will get x/3+6=x/3+10. WE then subtract x/3 on both sides to get 6=10. Since this cannot be true, there are no solutions.
Answer:
no solution
Step-by-step explanation:
[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2
[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )
[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )
0 = 4 ← False statement
This indicates the equation has no solution
when 7 is added to 3 times a number, the sum is multiplied by 2 and 15 is subtracted what is the final answer
Answer:
2(3x+7) -15
Step-by-step explanation:
Let x = unknown number
7 is added to 3 times a number
3x+7
Multiply the sum by 2
2(3x+7)
Subtract 15
2(3x+7) -15
Answer:
Let the required number be " x "
Now, 7 is added to 3 times a number : (3x + 7)
Next, the sum is multiplied by 2 : 2(3x + 7)
And then, 15 is substracted from it : 2(3x + 7) - 15
2(3x + 7) - 15 is the final answer.[tex]\huge\bold\red{{HELP}}[/tex]

The length of a side of a square is 4x – 1.
Express the area of the square in terms of x.
Answer:
16x^2 - 8x + 1
Step-by-step explanation:
1. The area of a square can be represented as s^2 or (s)(s), where s = side.
2. (Solving)
Step 1: Set up expression
[tex](4x-1)^2[/tex] [tex](4x-1)(4x-1)[/tex]Step 2: Apply the FOIL method (first, outside, inside, last)
[tex](4x)(4x)+(4x)(-1)+(-1)(4x)+(-1)(-1)[/tex] [tex]16x^2 -4x -4x +1[/tex]Step 3: Simplify.
[tex](16x^2)+(-4x-4x)+(1)[/tex] [tex]16x^2 -8x + 1[/tex]Therefore, the area of the square in terms of x is 16x^2 - 8x + 1.
