Step-by-step explanation:
68 divided by 77 is 0.88 approximately
100-88 is 12
Tip:
do this for increase and decrease in percentage question
divide small number by big number, and subtract the quotient from 100
Answer:
13%
Step-by-step explanation:
Percent increase is solved as such:
Percent Increase = %∧ = [tex](\frac{New~Amount~-~Original~Amount}{Original~Amount}) ~*~10[/tex]
%∧ = [tex](\frac{77~-~68}{68}) ~*~100 = (\frac{9}{68}) ~*~100 = 0.13 * 100 = 13\%[/tex]
Remember you want to know what percentage the difference is compared to how much your original amount is.
Hope this helps :)
(6x – 2) + (–x + 5) please help it is homework
Answer:
Step-by-step explanation:
You open the brackets;(6x-2)+ (-x+5)
6x-2-x+5
After Opening the brackets you group like terms;6x-x-2+5
•After grouping you proceed to simplify;
6x-x is going to be;
5x
•And then -2+5 is going to be positive 3 it's just like subtracting 2 from 5
Which is going to be;
5x+3
After you are done with this that's the final answer

A.6
B.-6
C.1/6
D.-1/6
Answer:
A. 6
Step-by-step explanation:
The reciprocal is the fraction flipped
1/6 would become 6/1
6/1 is basically 6
(You said the opposite reciprocal so I don't know if you meant the oppisite of the reciprocal but. . . . oh well. If you did mean that, then the answer would be C. 1/6)
Hope this helps :)

Answer:
[tex]m<49/12[/tex]
Step-by-step explanation:
we are given
[tex]y = 3x^2+7x+m[/tex]
To find x-intercept means we have to find zeros
and for finding zeros , we will use quadratic formula
and we have it has two x-intercepts
so, it's discriminant must be greater than 0
so, we will find discriminant
[tex]D = \sqrt{b^2-4ac}[/tex]
now, we can compare with
[tex]y=ax^2+bx+c\\y=3x^2+7x+m[/tex]
and then we can find a , b and c
a = 3, b = 7, c = m
now, we can find D
[tex]D = \sqrt{7^2-4*3*m} \\D=\sqrt{49-12m}[/tex]
It has two x-intercepts
so,
[tex]D = \sqrt{49-12m}>0[/tex]
now, we can solve for m
[tex]49-12m>0\\12m<49\\m<49/12[/tex]

The sum of 2 times a number and 8 is 7
Answer:
The number is -1/2
Step-by-step explanation:
Let x be the number
2x+8 = 7
Subtract 8 from each side
2x+8-8 = 7-8
2x = -1
Divide each side by 2
2x/2 =-1/2
x = -1/2
The number is -1/2
Answer:
2x + 8 = 7
x = -1/2
Step-by-step explanation:
"a number" can be signified by a variable.
So 2 times a number would give you 2x
And 8 would mean to add 8.
Is 7 means the end result is 7.
So 2x + 8 = 7
x = -1/2

The data below shows the points scored and minutes played by six basketball players during the 2004-2005 season. The least squares regression line for the data is y=.79x+1544
We assume data and prediction as question is incomplete
Answer and Step-by-step explanation:
Least squares regression line equations are used to model the relationship that exists between two variables, dependent and independent variables. The equation has the form y=a+bx where y is the dependent variable and x is independent variable, a is a constant and is the y intercept and b is the slope of the line. This relationship is then used to predict future outcomes.
Given that data for 2004-2005 for the basketball players are :
James- 20 points
John- 30 points
Chris- 50 points
Dave-15 points
Donaldson- 32 points
Richard -40 points
We predict the scores/points for James (for example) for the following year using the equation of the regression line y=0.79x+1544
We substitute his points x=20 I'm the equation:
Y=0.79*20+1544
=1599.8
The predicted value is 1599.8

A field goal kicker makes 84% of the field goals he attempts he has attempted 50 field goals this season how many goals hs he made
Answer:
He has made 42 field goals this season
Step-by-step explanation:
To find x% of number y, multiply y by [tex]\frac{x}{100}[/tex] ⇒ [tex]\frac{x}{100}[/tex] × y
∵ A field goal kicker makes 84% of the field goals he attempts
→ That means he makes 84% of his total attempts
∵ He has attempted 50 field goals this season
→ That means his total attempts is 50 field goals
∴ He makes 84% of 50 field goals
∵ 84% = 84 ÷ 100 = 0.84
∴ He makes 0.84 of 50
∵ He makes = 0.84 × 50
∴ He makes = 42 field goals
∴ He has made 42 field goals this season
